Getting Started
This section explains how to set up a standalone version Sentinel Express on a Rhino SDK.
Preparing to Install Sentinel Express
 |
Artifactory
This page refers to a public Artifactory instance that is no longer available. Please contact us via support if you require more information. |
Before you install Sentinel Express, you need to download the SDK package, and get other required software.
You can then either:
-
let the built-in installer install both the Rhino SDK and Sentinel Express, or
-
install and configure Rhino and the JVM manually, then use the installer to install Sentinel Express into your Rhino.
In both cases you need to get a license.
Allowing the installer to install both the Rhino SDK and Sentinel Express software is recommended for functional testing or experimentation with Sentinel Express. For production installs and/or load testing it is recommended to manually install and configure Rhino and the JVM.
Finally, if you are planning to install Sentinel Express on an existing OpenCloud Rhino installation, it makes sense to refer to other OpenCloud product dependencies
Download the Sentinel Express SDK package
To get the latest Sentinel Express SDK package go to https://repo.rhino.metaswitch.com/artifactory/opencloud-sentinel-express-3.1.0/opencloud/sentinel-pack/3.1.0/sentinel-express-sdk/ and choose the version with the highest release number.
The SDK package contains an installer, that can install Sentinel Express as an out-of-the-box system. It is also an SDK allowing customisation of the product.
| |
You will need OpenCloud-supplied credentials to download the package. |
Get required software
You’ll need the following software to run Sentinel Express:
| Software | Download Link | Documentation Link |
|---|---|---|
Java JDK 8 |
https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html |
|
Apache Tomcat 7.0.39 or greater (7.0.x series or 8.5.x series, not 9.x.x series) |
||
Rhino 2.7.0.0 or later - optional - to be used when installing and configuring Rhino manually |
||
Rhino Element Manager 2.7.0.0 or later |
||
Sentinel Express SDK including out of the box installer |
||
(Optional) Cassandra Database, version 2.1.17 or later version from the 2.1.x series |
Install and configure Rhino and the JVM
Optionally you can install and configure Rhino and the JVM for use with Sentinel Express. This is recommended for production deployments, and clustered setups.
Alternatively for Proof of Concept and lab functional testing it is recommended to use the Installer documented in Installing Sentinel Express Services
Install Rhino
1 |
Start by choosing a location to extract the contents of the Rhino package. We’ll refer to this directory as |
|---|---|
2 |
Rhino must be started at least once to generate the necessary configuration files. To start Rhino, in the $ ./start-rhino.sh (or |
3 |
Wait until Rhino is ready. It prints the following message in its log when ready: SLEE successfully started on node(s) [101] |
4 |
Stop Rhino by executing in the $ ./stop-rhino.sh --nice |
 |
For more about installing and configuring the Rhino TAS, please see the Rhino 2.7.0 Documentation. |
Configure Rhino and the JVM
If you want to install Sentinel Express on top of an already running Rhino then this step must be performed. If you are letting the installer configure the Rhino SDK for you, this step can be skipped.
The following settings are needed:
| Setting | Configuration |
|---|---|
|
Management database size |
For a full Sentinel Express install, the default Rhino 2.7.0 management database size is insufficient and should be increased to at least 300MB. To do this, edit <memdb>
<jndi-name>ManagementDatabase</jndi-name>
<message-id>10003</message-id>
<group-name>rhino-db</group-name>
<committed-size>300M</committed-size>
<stripe-count>1</stripe-count>
...
</memdb>
|
|
JVM |
You’ll also need to configure the JVM:
All of these settings can be found in |
|
Socket permissions |
You will need to add the host address where the installer is running to the mlet configuration file.
<mlets>
<mlet enabled="true">
<classpath>
<jar-url>$${rhino.dir.base.url}/lib/jmxr-adaptor.jar</jar-url>
<security-permission-spec>
.... other entries
permission java.net.SocketPermission "<IP ADDRESS>", "accept,resolve";
.... other entries
</security-permission-spec>
</classpath>
</mlet>
</mlets>
|
 |
Start Rhino to load the new configuration
To start Rhino, in the This applies the Rhino and JVM configuration. |
Get a license
| |
To install Sentinel Express you need a license to run SIS, CGIN, and Sentinel Express from OpenCloud. In order to obtain a license file, please contact OpenCloud. |
If you allow the installer to install both Rhino SDK and Sentinel Express for you, it will prompt you for the location of the license file.
If you prefer to set up Rhino manually, then you need to install the license file prior to installing Sentinel Express.
To install your license file:
1 |
Make sure Rhino is started and running. |
|---|---|
2 |
Go to the |
3 |
In this directory, start the Rhino Console with the |
4 |
In the Rhino Console execute, this command: installlicense [PATH_TO_LICENSE_FILE] ( |
Ports
If using the standard configuration, the following ports need to be open on the Express TAS host’s firewall.
| Port | Purpose |
|---|---|
5060 |
SIP traffic |
5061 |
Secure SIP traffic |
8080 |
REM GUI |
1199-1203 |
RMI Access |
If using other configuration the firewall should be configured for those non-standard ports. Other ports may be opened as needed. For example if ssh is used to administer a node, then port 22 would be opened

Installing Sentinel Express Services
Sentinel Express is installed through the use of an installer program.
The installer can run in interactive and non-interactive modes - suitable for manual and automated installs respectively. When running in interactive mode it will prompt you for various necessary settings and save them.
| |
The installer will offer to install the Rhino SDK for you, or allow you to specify an existing Rhino installation. Once either a new Rhino SDK install, or an existing installation is selected the installer will install Sentinel Express into your Rhino or Rhino SDK. |
The installer prepares configures for a single node Sentinel Express system.
For more advanced configurations, such as clustering, or multiple signalling peers, it is recommended the you become familiar with the Rhino platform, SIS and Sentinel Express products.
To install Sentinel Express services in interactive mode:
For further information on installation read:
1. Unzip sentinel-express-sdk.zip
To unzip sentinel-express-sdk.zip:
1 |
Copy the downloaded SDK zip file to a machine where Rhino and Sentinel Express will run.
user@machine$ mkdir ~/sentinel-express |
||
|---|---|---|---|
2 |
Unzip. user@machine$ cp ~/sentinel-express-sdk.zip ~/sentinel-express user@machine$ cd ~/sentinel-express user@machine$ unzip sentinel-express-sdk.zip |
2. Run the installer
The install program is split into several "phases".
These are:
-
initialisation of the environment
-
question and answer (in interactive mode)
-
execution of installation
| |
the installer captures full logging from the various tools that it uses, and writes these logs into the sentinel-express-sdk/build/target/log directory. |
To run the installer:
1 |
The testuser@machine$ cd ~/sentinel-express/sentinel-express-sdk testuser@machine$ ./build/bin/installer The installer first initialises the environment. It typically shows output similar to the following Initialising the SDK ... Retrieving Installer dependencies ... done. |
|---|---|
2 |
Question and answer to determine necessary settings The installer will prompt the user for various values. A value inside square brackets, if present, is the default answer for that question. When the user presses the Explanations of all of the questions the installer will ask are laid out over the next few steps. Note that some of the questions will only appear under certain circumstances, so not all of them will be seen in a given installer run. |
3 |
Taking the SDK offline The user is prompted as to whether or not they want to take the SDK offline. You can optionally take the SDK offline by creating a local repository. This will take several minutes depending on connection speed, but will make subsequent retrievals much faster and remove the need for an internet connection. Do you want to take the SDK offline? y/[N] > If the user presses the The user is then presented with progress information related to the downloading of artifacts necessary to take the SDK offline. This process can take more than 30 minutes. |

5 |
Install Rhino Questions You can either have the installer set up a Rhino SDK for you or point it at an existing Rhino installation, SDK or production. Note: If you want to use an existing Rhino installation it has to be running and a proper license has to be installed when finishing the installation after the configuration. Also make sure that you have adjusted the memory settings and created a tcapsim-gt-table.txt file as detailed in the documentation. Set up a Rhino SDK installation automatically? y/[N] > If you allow the installer to set up a new Rhino SDK installation, it will prompt for a license file. Enter the path to your Rhino license file > /home/testuser/Downloads/opencloud.license It then installs the Rhino SDK and starts it. If you instruct the installer to use an existing Rhino, the installer will prompt for the path to the Rhino client directory. Enter the path to your Rhino client directory > /home/testuser/rhino/2.4/client If the associated installation is a Rhino production then additional information is required to complete configuration. You can either have the installer deploy against Rhino SDK or production. Does the specified client point to a production installation? y/[N] > If you choose Yes, then the installer prompts for details of the cluster nodes and hosts. Enter your Rhino node setup.
It has to be formatted like this: {nodeId,nodeId}host,{nodeId}host
Examples:
{101}localhost
{101,102}host1,{103}host2
Node setup [{101}localhost] > {101}hostname1,{102}hostname2

| |
A properties file is automatically created when the interactive installer is run. This file is located in the sentinel-express-sdk directory and named install.properties. In this way an interactive installations settings are saved, and can be distributed through the install.properties file. You can later use this file for a new installation using the Non-interactive mode. |
Non-interactive mode
To run the installer in non-interactive mode a properties file must be passed to the installer program.
testuser@machine$ cd ~/sentinel-express/sentinel-express-sdk testuser@machine$ ./build/bin/installer -p my-install.properties
SIS and CGIN
During installation SIS and CGIN versions are extracted into the SDK directory structure. This is so that SIS can be configured as necessary.
The CGIN connectivity pack is extracted into the sentinel-express-sdk/cgin/cgin-connectivity-full-CGIN_VERSION directory. The SIS is extracted into the sentinel-express-sdk/sis/SIS_VERSION directory. Here CGIN_VERSION and SIS_VERSION are the release versions for each product respectively (e.g. 2.0.0.0 and 2.7.0.0)
The SIS console command is located at sentinel-express-sdk/sis/SIS_VERSION/admin/sis-console.
Background information
The installer sits on top of the Sentinel Express SDK infrastructure
The installer works by creating "deployment modules" for the products within Sentinel Express. These modules are named "deploy-sentinel", "deploy-sentinel-sip", "deploy-sentinel-ss7" and "deploy-sentinel-diameter". They are located in the root of the Sentinel Express SDK directory.
A deployment module can be created through the use of the sdkadm create-deployment-module command.
The deployment modules are then published, and the deployer, binder and configurer are invoked in order to install/bind/configure the application in Rhino.
This means that the the installer is part of the Sentinel Express SDK, and that there is no technology difference between the SDK and an "off the shelf install". Therefore custom configurations can easily be made through modifying the deployment modules, publishing them, and running the configurer.
Installer log files
The installer captures full logging from the various tools that it uses, and writes these logs into the sentinel-express-sdk/build/target/log directory. This output is more verbose than the user sees when running the installer.
Each time an install is done, a file called installer.log is created in this directory. If there is a previous installer.log file, it is moved to installer_[date].log. The value of [date] is the time of the last write timestamp in the file.
Therefore running the installer three times results in three installer log files.

Security considerations
Below are recommendations for securely running the Sentinel Express Provisioning Module.
Use https
Be aware that the Sentinel Express machine API uses HTTP BASIC authentication. This passes the username and password with every request.
To prevent your credentials going over the network unencrypted, run REM over https.
Set up SSL
See the Tomcat 7 - SSL How-To docs for help setting up SSL in Apache Tomcat 7.

Description
Configuration name |
Tcc Timer |
|---|---|
Applicable contexts |
SS7/SIP/Diameter service |
The TccTimer configuration determines how the Sentinel-internal Tcc timer will be set when a CreditControlAnswer is received from the OCS.
Each time a CreditControlAnswer from the OCS is received by the mediation layer and subsequently passed on to the frontend layer (Diameter, SS7 or SIP service), Sentinel starts the Tcc timer which is supervising the responsiveness of the frontend/client. The duration of this timer is determined by the TccTimer configuration. It can be:
-
via a formula based on the Granted-Service-Units (GSU) AVP of the received CreditControlAnswer and configuration parameters for offsets and multipliers:
Duration = (GsuScaleFactorMultiplier * GSU)/GsuScaleFactorDivisor + GsuOffset
-
calculated via a formula based in a similar way on the Validity-Time (VT) AVP:
Duration = (VtScaleFactorMultiplier * VT)/VtScaleFactorDivisor + VtOffset
-
switched off completely
-
set to a constant value.

Activity Test Configuration — The Activity Test configuration determines when Sentinel will test for the continued liveness of a session that has had a period of inactivity.
Activity Test Configuration
Description
Configuration name |
Activity Test |
|---|---|
Applicable contexts |
SS7 service, SIP service |
The Activity Test configuration determines when Sentinel will test for the continued liveness of a session that has had a period of inactivity.
Whilst a session is being monitored, Sentinel runs a timer where the duration is based on the Activity Test configuration. The timer is stopped each time Sentinel receives incoming traffic on the session. If the session is still active once the message has been processed, then the timer is restarted again. If the timer expires, Sentinel tests the activity/liveness/validity of the session using an appropriate protocol specific method. If this test fails, the session is terminated.

Activity Test Configuration for SIP
Description
Configuration name |
Activity Test |
|---|---|
Applicable contexts |
SIP service |
The Activity Test configuration determines when Sentinel will test for the continued liveness of a SIP session that has had a period of inactivity.
During the active call period, Sentinel runs a timer where the duration is based on the Activity Test configuration. The timer is stopped each time Sentinel receives a message from the external SIP UAC/UAS; and if the call is still active then the timer is restarted again. If the timer expires, Sentinel sends re-Invite messages to test that the connection to the external SIP UAC/UAS is still active. If the Activity Test fails, the session is terminated.

Activity Test Configuration for SS7
Description
Configuration name |
Activity Test |
|---|---|
Applicable contexts |
SS7 service |
The Activity Test configuration determines when Sentinel will test for the continued liveness of a dialog that has had a period of inactivity.
During the active call period, Sentinel runs a timer where the duration is based on the Activity Test configuration. The timer is stopped each time Sentinel receives a message from the MSC such as an Apply Charging Report; and if the call is still active then the timer is restarted again. If the timer expires, Sentinel sends an Activity Test operation on the dialog to test that the connection to the MSC is still active. If the Activity Test fails, the session is terminated.
| |
The configuration is in common with the SIP service. See Activity Test Configuration. |
Call Information Report Configuration
Description
Configuration name |
Call Information Report |
|---|---|
Applicable contexts |
SS7 service |
The Call Information Report configuration determines if Sentinel will request Call Information Reports from the network for an SS7 first-party call and if call alerting time will be chargeable for Mobile Originating calls. Call Information Reports can be used for more accurate charging as they’re produced directly by the MSC/SSF controlling the call and are therefore not influenced by network or external resource latencies in the service.
Any Call Information Reports received by Sentinel are also included in the CDR produced for the call.
Configuration
The default behaviour of Sentinel is:
-
to request Call Information Reports from the network for both originating and terminating call parties
-
not to charge for call alerting time.
| |
A-party or B-party Call Information Reports can be suppressed in order to reduce network traffic. |
In the case where the terminating party report is not suppressed, Sentinel can use this report when finalising the amount of credit consumed by the subscriber. For a Mobile Originating (MO) call this report can also be used to charge the subscriber for the call alerting time.
The Call Information Report configuration includes:
| Parameters | Value | Description |
|---|---|---|
SuppressOriginatingPartyCallInformationReport |
Boolean |
Boolean, if true, stops Sentinel from sending a Call Information Report request for the originating call party. |
SuppressTerminatingPartyCallInformationReport |
Boolean |
Boolean, if true, stops Sentinel from sending a Call Information Report request for the terminating call party. |
CallAlertingTimeIsChargeable |
Boolean |
Boolean, if true, will cause Sentinel to also charge the subscriber for call alerting time (MO calls only). This option can only be set to true if |
CallAlertingTimePrereservationSeconds |
The number of seconds of credit to pre-reserve in the initial credit reservation if call alerting time is chargeable. This value should be set to the maximum expected alerting time. This option is only relevant if |
|
CirTimeout |
The number of milliseconds to wait for CIRp before timeout and continuing the session. May be set between range 500 - 10000, with a default of 3000. |

SLEE usage parameter sets
Resource Adaptors
In the SLEE component model, a resource adaptor (RA) provides the interface between the application and the network. It adapts the physical resource to events which the SLEE can send and receive. Sentinel makes use of a number of resource adaptors, for purposes ranging from database connections to network integration.
OpenCloud Resource Adaptors used by Sentinel
Sentinel may install various Resource Adaptors and configure RA entities. This actual RAs and RA entities installed and configured varies based on which components are used.
The Resource Adaptors Entities may include:
-
diameterro-0 — adapts outbound sessions with multiple OCSes; speaks Diameter Gy and Ro
-
diameterro-1 — adapts inbound sessions with multiple Diameter clients; speaks Diameter Gy and Ro
-
cgin — adapts inbound CAP sessions for CAMEL IN integration
-
http — adapts inbound http triggers for things such as 3rd-party call initiation
-
cdr — for writing of call detail records (or 3GPP Charging Data Records)
-
correlation-ra — maps an item of data to a unique ID for lookup; currently used for call reorigination
-
dbquery-0 — manages relational database connections through JDBC
-
hector — manages Cassandra connections
-
uid — generates unique IDs for miscellaneous use by Sentinel features and services
-
sip-sis-ra — adapts inbound SIP sessions for SIP network integration
| |
All these RAs can be viewed and configured using the Sentinel Element Manager. Future releases of Sentinel will have resource adaptors to support other protocols, such as Diameter CCA. Customers can also add their own resource adaptors, using the Sentinel SDK. |
CGIN RA
The Sentinel SS7 service uses the CGIN RA for SS7 integration. For details on configuring the CGIN RA, see the CGIN documentation.
CDR Resource Adaptor
CDR resource adaptor entities
The Sentinel installer creates a CDR resource adaptor entity called cdr. This resource adaptor entity is used by all Sentinel services.
CDR resource adaptor configuration
| |
Refer to the CDR RA Documentation for more information about the CDR RA. |
The cdr resource adaptor entity is configured to use the cdr-stream profile of the CdrStreamConfiguration profile table by default.
The output behaviour of the CDR resource adaptor can be customised by modifying this profile in accordance with the CDR RA Documentation.
Sentinel configuration requirements
The cdr RA entity must be configured with CdrFileType=Binary.
For more information about CDRs in the Sentinel platform, refer to:
-
Working with CDRs section of this administration guide to learn about the content of Sentinel CDRs.
-
Customising CDRs in the Extending Sentinel with the SDK guide to learn how to customise the format of the CDRs that Sentinel creates, as well as customising the data included in the CDRs.
CGIN Resource Adaptor
CGIN resource adaptor entities
| |
Refer to the CGIN documentation for more information about the CGIN resource adaptor. |
There are two CGIN resource adaptor entities in Sentinel:
-
cginra— for CAP dialogs -
cginmapra— for MAP dialogs.
CAP CGIN RA entity (cginra)
The cginra RA entity is used for initiating and third party CAP dialogs.
MAP CGIN RA entity (cginmapra)
The cginmapra is used by features to initiate MAP dialogs.
Configuring the local-sccp-address
Inter-operator MAP requests require an SSN of 147. The local-sccp-address of the cginmapra RA entity must be configured with sccp address including SSN=147.
Configuring the default-activity-timeout
By default the default-activity-timeout is set to 1800000 (30 minutes) by default. This is too long for the MAP features in Sentinel. It is recommended to set it to a shorter value in the cginmapra RA entity.
Set default-activity-timeout high enough so that the MAP invoke timeouts will be first, taking into account the granularity of signalware/telesys timers, but low enough that hung dialogs do not accumulate, which will cause the RA entity to run out of dialog identifiers while waiting for activity timeout to terminate the hung dialogs.
For instance, if Sentinel MAP features have a maximum invoke timeout of 5 seconds then 10 seconds (10000) would be sufficient for the default-activity-timeout.
Customising the CGIN RA entities used by Sentinel
It may be necessary to configure multiple RA entities to address specific operator network configuration requirements. Additional CGIN RA entities may be used in Sentinel for this purpose. Sentinel has the following link binding by default:
| Link name | Default Bound RA entity |
|---|---|
|
|
|
|
|
|
|
|
|
|
|
|
A custom CGIN RA entity may be used by creating, configuring and binding the new RA entity.
Correlation Resource Adaptor
Correlation RA Overview
What is the Correlation RA?
There are situations where Sentinel must correlate two independent sessions. The Correlation RA allocates a correlation ID with the first session, that can then be used to process a second session. The Sentinel service may associate a blob of data with an allocated correlation ID.
The Correlation RA is used for two cases in Sentinel:
-
Playing an announcement using ETC/ARI. In this case, the Correlation RA is used to allocate the correlation ID that is included in the ETC message, which is then present in the ARI message sent on a second dialog.
-
Roaming Re-origination Feature. In this case, the Correlation RA is used to allocate a special routing address that is used in the Connect message on the initial dialog. A second re-originated dialog will be received by Sentinel for this special address. Sentinel uses the Correlation RA on the re-originated dialog to retrieve data that was associated with the special address via the first dialog. The associated data includes relevant details from the InitialDP of the initial dialog.
Below are procedures for [configuration], [monitoring], and [using].
Configuring a Correlation RA entity
A Correlation RA entity configuration consists of:
The following diagram shows the Reorigination Correlation RA entity.
| |
The Correlation resource adaptor supports live re-configuration, so the administrator may update the configuration properties of a Correlation resource adaptor entity that has already been created. |
Correlation RA configuration properties
The Correlation RA configuration properties are:
Name |
Type |
Description |
|
String |
The SLEE profile table with an RA configuration profile for this RA entity. |
|
String |
The SLEE profile in the ConfigProfileTable with configuration for this RA entity. |
|
String |
The SLEE profile table with correlation ID pool definitions for this Correlation RA entity. |
For example, the Reorigination Correlation RA entity has the following configuration:
[Rhino@localhost (#9)] listraentityconfigproperties reorigination-correlation-ra Configuration properties for resource adaptor entity reorigination-correlation-ra: ConfigProfile (java.lang.String): ReoriginationCorrelationConfigProfile ConfigProfileTable (java.lang.String): CorrelationConfigTable CorrelationIdPoolTable (java.lang.String): ReoriginationCorrelationIdPools
Correlation RA entity configuration profile
The Correlation RA configuration profile has the following attributes:
Name |
Type |
Description |
|
Int |
The maximum time (measured in ms) the Correlation RA will spend trying to allocate a correlation ID. |
|
Int |
The maximum time (measured in ms) that an active correlation ID is considered to be still valid. |
|
Int |
How many threads the Correlation RA entity should use. |
For example, the Reorigination Correlation RA entity has the following configuration:
[Rhino@localhost (#8)] listprofileattributes CorrelationConfigTable ReoriginationCorrelationConfigProfile CorrelationIDExpiryTimerPeriod=55000 NumberOfThreadPool=5 RequestTimeout=5000
Correlation RA entity ID pools configuration
Each Correlation RA entity has one or more correlation ID pools.
-
a default ID pool (optional)
-
a set of named ID pools. Each named ID pool is identified by a set of prefixes for choosing/selecting the ID pool. From the Correlation RA standpoint, the prefixes can be any address string. The client to the RA provides an address that the RA uses via a longestPrefix match address list search to select the pool to use.
Each correlation ID pool is defined in a SLEE profile in an ID pools profile table. There is one correlation ID pools table per Correlation RA entity.
| |
The correlation resource adaptor entity will raise an alarm if there are no correlation ID pools configured, or if there are configuration errors with the correlation ID pools. |
|
An array of address prefixes that corresponds to this pool. The default pool has an empty addressPrefixes array. |
|
An array of node IDs for which this pool has correlation IDs. |
|
If true, configure this ID pool with a pre-configured set of correlation IDs, else derive the correlation IDs. |
|
The preconfigured set of correlation IDs per node (delimited with ‘:’). |
|
The minimum correlation ID value used in the cluster. 0 to maxCorrelationIDInCluster |
|
The maximum correlation ID value used in the cluster. 0 to (10^18-1) |
|
The number of digits the correlation ID should have. Minimum of number of digits in maxCorrelationIDInCluster to 18 maximum. |
|
The number of correlation IDs that can be used for each node in the cluster. |
There are two possible configuration options for correlation ID pools.
A prescribed set of IDs for each node
Defines the prescribed correlation IDs for each node in the following way:
-
NodeIds[0]—PreconfiguredCorrelationIdSet[0]which is a ‘:’ separated string containing all the correlation IDs forNodeIds[0] -
NodeIds[1]—PreconfiguredCorrelationIdSet[1]which is a ‘:’ separated string containing all the correlation IDs forNodeIds[1] -
etc.
| |
‘:’ is used as a separator and not to specify a range. For example, to specify IDs 123, 124, 125 and 126 use a value of 123:124:125:126. |
A range of correlation IDs (min, max) for each node
Defines the range of values used in each node in conjunction with the NodeIds attribute in the following way:
-
The node whose identifier is
NodeIds[i]has a range of values ofCorrelationIDRangePerNode[i] -
Each cluster has a range of CorrelationIDs defined by:
[MinCorrelationIDInCluster, MaxCorrelationIDInCluster]
These values are allocated to the different cluster nodes in the following way:
-
NodeIds[0]—[MinCorrelationIDInCluster … MinCorrelationIDInCluster + CorrelationIDRangePerNode[0]] -
NodeIds[1]—[MinCorrelationIDInCluster + CorrelationIDRangePerNode[0] + 1 … MinCorrelationIDInCluster + +CorrelationIDRangePerNode[0] + 1 + CorrelationIDRangePerNode[1]] -
etc.
The maximum number of correlation IDs defined in the range is 1,000,000.
Provisioning Interfaces
The Correlation RA configuration and ID pools are provisioned using the Sentinel REST API or web interface.
Monitoring Correlation RA entity statistics
Each Correlation RA entity collects the following statistics that may be monitored via the Rhino statistics client.
Counters
| Name | Description |
|---|---|
|
Count of correlation IDs which have been requested via |
|
Count of correlation queries which returned immediately (synchronous delivery) as the local RA had the data available. |
|
Count of correlation queries which did not return immediately (asynchronous delivery) as the local RA did not have the data available. |
|
Count of correlation queries which required delivering data to another correlation RA instance. |
|
Count of correlation queries which could not be remotely delivered as the destination RA for a correlation ID was unknown. |
 |
The count correlationGets should equal the sum of localGets + remoteGets. |
These statistics can use used to create threshold-based alarms.
Using the Correlation RA
A feature uses the Correlation RA by invoking methods on the provider interface.
-
To store data for correlation, a feature calls either the
getNewCorrelationID(byte[] correlationData)or thegetNewCorrelationID(String associatedAddress, byte[] correlationData)method on theCorrelationProvider. These methods will store the correlation data locally, and return an identifier String (the correlation ID) which can later be used to access the data from elsewhere. This operation will flag the returned ID as ‘in use’ until it is freed (on query) or expires (on timeout). -
To query the correlation data (for example, from another session) a feature calls the
getCorrelationData(String correlationId)method on theCorrelationProvider. This returns aCorrelationResultwhich will either contain the requested data (if it is available locally), or a flag indicating that the data is not available locally. -

}
Handling synchronous results
Synchronous queries occur when the RA which is queried is also storing the queried information. In these circumstances, the data is included in the returned CorrelationResult from a query. The following example demonstrates how to handle synchronous return results:
private void syncRequest(byte [] correlationData) {
//
// Store some data against a new correlation ID.
//
String correlationId;
try {
correlationId = corrProvider.getNewCorrelationID(correlationData);
} catch (NoAvailableEntriesException e) {
// ... handle exception ...
return;
}
// ... do work until correlation data is required again.
// In practice, the following will usually be done in another transaction which only knows the correlation ID.
// It is done inline here for the sake of simplicity.
//
// Query the saved correlation data.
//
try {
CorrelationResult result = corrProvider.getCorrelationData(correlationId);
byte [] corrData = result.getCorrelationData();
if (corrData != null) {
// Do something with data
} else {
if (result.isAvailableAsynchronously()) {
// ... Here we could optionally proceed with an asynchronous correlation data query. See following example.
}
}
} catch (UnknownCorrelationIdException e) {
// ... handle exception ...
return;
} catch (NoDataFoundException e) {
// ... handle exception ...
return;
} catch (CorrelationIDExpiredException e) {
// ... handle exception ...
return;
}
}
Handling asynchronous results
Asynchronous result handling is required when the correlated data for the requested ID is only available from a non-local Correlation RA (that is, on a different Rhino node). After the correlation data is requested, the result is returned in a CorrelationEvent which is delivered to the service. This CorrelationEvents must be explicitly handled with a SLEE event handler.
Requesting correlation data asynchronously is done as follows:
-
Create a new correlation activity using
CorrelationProvider.createActivity() -
Get an
ActivityContextInterfaceobject for the activity. -
Attach the SBB local object to the ACI.
-
Send the request using the
requestCorrelationData(String)method on the activity. -
Handle the result in an event handler for the
com.opencloud.slee.resources.correlation.CorrelationResultEventevent. -
Handle failures in an event handler for the
com.opencloud.slee.resources.correlation.CorrelationFailureEventevent.
The follow example demonstrates the handling an asynchronous correlation query:
private void asyncRequest(String correlationId) {
try {
CorrelationActivity corrActivity = corrProvider.createActivity();
ActivityContextInterface corrAci = corrACIFactory.getActivityContextInterface(corrActivity);
corrAci.attach(getSbbLocalObject());
corrActivity.requestCorrelationData(correlationId);
}
catch (StartActivityException e) {
// ... handle exception ...
}
}
public void onCorrelationResult(CorrelationResultEvent result, ActivityContextInterface aci) {
aci.detach(getSbbLocalObject());
byte [] corrData = result.getCorrelationData()
// ... do something with the data ...
}
public void onCorrelationFailure(CorrelationFailureEvent failure, ActivityContextInterface aci) {
aci.detach(getSbbLocalObject());
// ... handle failure ...
}

DBQuery Resource Adaptor
DBQuery resource adaptor entities
The Sentinel installer creates a DBQuery resource adaptor entity called dbquery-0. The dbquery-0 resource adaptor entity is configured to connect to a local relational database.
| |
See the DBQuery RA documentation for more about the DBQuery RA. |
DBQuery database type
Before installing Sentinel, you can configure the DBQuery RA database type by adding the db.type property to sdk.properties or sdk.local.properties. Valid options for this property are postgres, oracle, and timesten. The Sentinel installation process compiles the DBQuery RA with the appropriate JDBC driver for that db.type.
Many features provided with Sentinel, and new features developed with the Sentinel SDK, may use the DBQuery resource adaptor.
Features that may use the DBQuery resource adaptor
The following features provided with Sentinel may be configured to use the DBQuery resource adaptor:
-
Scripted Promotions Feature — may be configured to use a database to store the promotions buckets
-
Friends and Family Feature — may be configured to fetch friends and family data from a relation database
-
Home Zone Feature — may be configured to fetch home zone data from a relation database
-
Subscriber Data Lookup Feature — may be configured to fetch subscriber data from a relation database
| |
See Provisioning Configuration and Provisioning Data in TimesTen for how to manage data in an external database using the Sentinel Element Manager. |
Diameter Resource Adaptor
Diameter resource adaptors
There are currently three diameter resource adaptor entities in Sentinel:
-
diameterro-0— for OCS connections -
diameterro-1— for client connections -
diameter-sentinel-internal— used as a message factory by mappers in Sentinel’s Diameter mediation layer.
diameterro-1 is available only to the Sentinel Diameter service. diameterro-0 and diameter-sentinel-internal are used by all Sentinel services.
Session timeouts
The default Sentinel configuration has a 10 minute timeout for diameterro-1 (client) and 13 minute timeout for diameterro-0 (OCS). This configuration ensures that if there are events dropped due to overload, the ActivityEndEvents fired on the RA entities will cause the client side to end first. The 3 minute gap is set to allow time for all the ActivityEndEvents on the client side to be delivered before any are fired on the OCS side due.
Diameter version configuration
The Diameter version spoken on the network to either the OCS or the Diameter client can be configured by setting two properties in the relevant resource adaptor. To change the version used in the OCS dialog, diameterro-0 should be reconfigured. Likewise, to change the version used on the client dialog (Sentinel Diameter only), diameterro-1 should be reconfigured. The Diameter version used by diameter-sentinel-internal should not be reconfigured, as it is tied to the internal implementation of Sentinel.
When reconfiguring the Diameter version of either of the external resource adaptors, two fields must be set - Slee3GPPVersion and 3GPPVersion. Slee3GPPVersion should always be set to Vcb0. This is the version of Diameter used by Sentinel internally. 3GPPVersion can be set to the desired protocol version to be used over the network, ranging from V820 to Vcb0.
Alternatively, the Diameter version spoken to the OCS can be set during installation.
OCS load balancing
Load balancing of OCS connections can be achieved using the diameterro-0 resource adaptor entity, by configuring multiple hosts within a realm and addressing messages to the realm only (not the host).
Example configuration for OCS load balancing
This example shows the diameterro-0 resource adaptor entity configured to load balance across two OCS nodes.
-
The resource adaptor entity config properties show that it is configured using a profile in the
DiameterConfigtable. -
The config profile shows that the known OCS nodes are named
diameterserveranddiameterserver1. -
The routing priority metric for both nodes is set to 1 to indicate equal priority, meaning that load balancing will be applied.
-
The
DiameterMediationOcsConfigurationTableconfiguration profile at platform scope does not specify a host, so all outbound Diameter messages will not have the destination host set, but only the realm. This means the resource adaptor entity will round robin among all the hosts configured for the specified realm (in this caseopencloud). However this behaviour can be overridden on a per-session basis by setting theOCSIdfield in session state using, for example,SubscriberDataLookupor a custom feature added with the SDK.
The following rhino-console session shows the complete configuration:

SIP SIS Resource Adaptor
SIP SIS resource adaptor entity (sip-sis-ra)
| |
Refer to the Service Interaction SLEE (SIS) documentation for more information about the SIP SIS resource adaptor. |
The sip-sis-ra is used for initiating and third-party SIP dialogs for both the Sentinel SIP Service and the Sentinel Subscription Service.
| Link name | Default Bound RA entity |
|---|---|
|
|
Sentinel and SIS
The sip-sis-ra interacts directly with the SIS, which is configured with compositions for the Sentinel SIP Service. The Sentinel SIP Service is triggered by all events from the SIP SIS RA entity. This behaviour is configurable. See the Service Interaction SLEE (SIS) documentation for more information about compositions and triggers.
Configuring SIS
Use the sis-console or SIS REM Module to modify the default SIS and sip-sis-ra configuration properties; see the SIS Administration Guide and SIS REM Module User Guide for more details on managing the SIS instance.
Unique ID Resource Adaptor
What is the Unique ID RA?
The Unique ID RA generates and returns guaranteed cluster-wide unique identifiers. New identifiers can be requested up to a limit of 512 per millisecond at a steady rate.
| |
The identifiers are only guaranteed to be unique for a single Unique ID RA entity |
Usage within Sentinel
The Sentinel SS7 Service uses the Unique ID RA to generate unique call reference numbers for non-SS7 triggered calls. All Sentinel services make a Unique ID RA provider available for injection into features, including custom features developed by third-party integrators using the Sentinel SDK. Sentinel Charge users can also make use of the Unique ID RA in their services.
Configuring the Unique ID RA entity
The Unique ID RA requires no configuration of any kind as it retrieves all the resources necessary for operation from Rhino. A Unique ID RA entity is ready for operation as soon as it is activated. The name of the standard RA entity used by Sentinel is uid.

General Features
Sentinel includes many features that are useable in many networks:
-
Do Not Charge Session Feature — Notifies the Sentinel core to not charge the session.
-
Http Determine Network Operator Feature — Extracts the name of the Network Operator from an HTTP request.
-
OcsParameterConfiguration Feature — Sets the value of two session state fields related to determining the number of units to request from the OCS.
-
Platform Operator is Network Operator Feature — Updates the Sentinel selection key so that the network operator is the same as the configured platform operator.
-
Session Tracing Activation Feature — Used to determine if session tracing should be performed on this session or not, based on the subscriberId session state field.
-
Subscriber Data Lookup Feature — A pre-credit check feature used to query subscriber-specific information from a relational database and store it in session state, for use by Sentinel features and mappers.
-
Subscriber Validity Feature — Performs a check that a subscriber is within a validity period within two inclusive dates.
Do Not Charge Session Feature
Description
Feature name |
DoNotChargeSession |
|---|---|
Applicable contexts |
SS7 Service, SIP Service |
SAS Support |
No |
Prerequisite Features |
None |
Notifies the Sentinel core to not charge the session. If Sentinel decides to let the session proceed, it will be a free session. Sentinel may still monitor the session unless another feature instructs Sentinel to not monitor the session (see DoNotMonitorSession feature). This is an initial trigger feature which can run before or after the credit check. If run before the credit check, it will prevent the credit check taking place and Sentinel will not establish a session with the OCS. If run after the credit check, it will cause Sentinel to finalize the OCS session reporting 0 used units.
| |
Immediate Event Charging behaviour When Immediate Event Charging (IEC) is used (for example, for SMS) then running this feature post-credit-check can result in a refund being sent to the OCS if the session was previously charged. Running this feature pre-credit-check will result in no OCS interactions. Session termination methods such as ConnectAndClose and ContinueAndClose will not refund credit by default, so if a refund is required in those cases then this feature must be run post-credit-check. |
HTTP Determine Network Operator Feature
Description
Feature name |
HttpDetermineNetworkOperator |
|---|---|
Applicable contexts |
SS7 Service, SIP Service, Sentinel Charge Example |
SAS Support |
No |
Prerequisite Features |
None |
Extracts the name of the Network Operator from an HTTP request. This feature searches the request URL parameters for a name-value pair with name identified in the HttpParameterForHttpDetermineNetworkOperator field of the SentinelPlatformConfiguration. The feature then attempts to map the discovered value to a network operator name by looking it up in the SentinelHttpParameterToNetworkOperatorProfileTable. If the parameter is not found in the URL or there is no mapping available in the SentinelHttpParameterToNetworkOperatorProfileTable, a default network operator is used, as configured in the DefaultNetworkOperator field of the SentinelPlatformConfiguration.
For example, consider an HTTP trigger containing the following URL:
HttpDetermineNetworkOperator will query the name of the HttpParameterForHttpDetermineNetworkOperator in the SentinelConfigurationTable by selection key. In this case it returns “calledstationid”. The corresponding parameter value 00102 is then extracted from the URL, and the profile of the same name is retrieved from the HttpParameterToNetworkOperatorProfileTable. From this profile, the NetworkOperator is retrieved and stored in session state.

true/false. True selects list screening; false selects random tracing of sessions. |
For the percentage of calls, a configuration profile will be maintained with the percentage of calls to be matched.
Percentage setting:
-
0 — no calls are enabled
-
1 — 1 in 10000 (or 0.01%) of calls are enabled
-
10 — 10 in 10000 (or 0.1%) of calls enabled
-
100 — 100 in 10000 (or 1%) of calls enabled
-
1000 — 1000 in 10000 (or 10%) of calls enabled
-
No other configuration values valid
| |
Any value above 10% of calls is out of the scope of this capability. 100% is already provided by the standard tracers. |
Address list configuration
If list screening is activated, the Session Tracing Activation Feature uses a list of subscriberIds that, if matched to a session, will switch on tracing for the session. See Address lists for information on how to configure the address list data.
Tracing output
Tracing output will be sent to the parallel session branch of the trace key tree (that is, session.sentinel rather than sentinel). The level of the session tracing is determined by the trace levels of each key in that tree.
The session tracing prefix will be set to the value of subscriberId.

Configuration
Subscriber record field configuration:
The feature is configurable to allow additional fields to be added to the subscriber record and associate the additional or existing fields with with new or existing session state fields. These field definitions are configured in the ${SELECTIONKEY}SubscriberDataLookupFieldDefinitionProfileTable as follows:
| Field | Type | Description |
|---|---|---|
ColIdx |
String |
Indicates the column index of this field in a subscriber data record. Should match the profile name. |
InsertParamIdx |
int |
Indicates the column index of this field in a subscriber data record. Should match the profile name. |
ResFieldname |
String |
Name of the field when read into a result record |
SessionStateFieldname |
String |
Name of the session state field this field should be loaded into |
Type |
String |
The type of the field, both in session state and in the data source. Supported types: String, Boolean, Integer, String[], Date[], Date |
UpdateParamIdx |
int |
Indicates the column index of this field in a subscriber data record. Should match the profile name. |
The table of fields used for the mapping are scoped to the Sentinel selection key. The selection key may be configured at the following levels:
-
Platform operator
-
Network operator
-
Session type
-
The field definitions are configurable by Sentinel selection key.
The Subscriber Data Lookup feature may retrieve the subscriber record from:
-
MySQL via JDBC
-
TimesTen via JDBC
-
Oracle via JDBC
-
Cassandra database (experimental).
-
JSLEE profiles (testing purposes)
Data source configuration
The choice of data source type is configured in the SubscriberDataLookupConfigProfileTable:
| Field | Type | Description |
|---|---|---|
LookupType |
String |
One of dbQuery, profile, profileIms, or Cassandra |
| Lookup type | Description |
|---|---|
dbQuery |
Uses the dbquery-0 ra entity to perform the subscriber data query. This option is used for all the different RDBMS types such as MySQL, Oracle, and TimesTen. The type of database used and the associated settings are configured in the {{dbquery-0}}resource adaptor entity configuration. See DBQuery Resource Adaptor for further configuration information. |
profile |
Uses the ${PLATFORMOPERATOR}_SubscriberDataRecordProfileTable for the lookup. Only suitable for small sets of subscribers for testing and development purposes. |

Subscriber Validity Feature
Description
Feature script name |
SubscriberValidity |
|---|---|
Applicable contexts |
All services |
SAS Support |
No |
Prerequisite features |
The Subscriber Validity feature performs a check that a subscriber is within a validity period within two inclusive dates. If the start date is not present, all dates prior to the end date are considered valid. If the end date is not present, then all dates from the start date are considered valid.
The validity dates are set on a per-subscriber basis.
If the current date at session initiation is within the valid period for the subscriber, the feature will have no effect on the call.
If the current date at session initiation is outside the valid period for the subscriber, the feature will release the call.
OCS interface
This feature has no interaction with the OCS (except for preventing the initial credit check by releasing the session).

Description
Feature name |
FlashSms |
|---|---|
Applicable contexts |
|
SAS Support |
No * Diameter service * SIP service |
Prerequisite features |
A feature to set the NotificationMessage and NotificationAddress session state variables |
The notification information will be accessed from the NotificationMessage session state variable which was set by a prior feature. The supported data coding schemes are GSM_7BIT and UCS2 — the message will be sent using the GSM_7BIT coding scheme if it can be represented in the 7-bit alphabet; otherwise, the UCS2 coding scheme will be used.
The notification message will be sent to (in order of precedence):
-
Address in NotificationAddress session state variable (if set)
-
Address in Subscriber session state variable.
If neither of these variables are set then the message will not be sent.
The feature checks the IMSI and MSCAddress session state fields. When both are set the feature will not perform an SendRoutingInformationForSM but use the MSCAddress session state field instead.
| |
MTForwardSM will return success if the handset is available and message delivered. If it’s not, then a error response will be returned that the message was not deliverable (absent subscriber, and so on). As the call is either in progress or has just ended, the message will be deliverable in the vast majority of cases so no special behaviour is required in the error cases after sending MTForwardSM. Sentinel will not attempt to retry sending the message if there is an error delivering the message for any reason. |

Call flow
There are two MAP requests as party of the MTForwardSM process:
-
Obtaining the routing information from the HLR.
-
Sending the MT SMS.
The first step is performed by sending an SendRoutingInformationForSM request to the HLR to determine the routing information for the MT Forward SM. This step is not performed if the IMSI and MSCAddress session state fields are set.
The HLR SCCP Address will be based on the MSISDN of the subscriber. (See MAP SPEC Section 4 Requirements concerning the use of SCCP and TC/4.1.3.3 The Home Location Register (HLR) — refer to MAP SPEC footnote). The MSISDN will be retrieved from SessionState.NotificationAddress or SessionState.Subscriber.
hlrSccpAddress.address={SessionState.NotificationAddress or SessionState.Subscriber)
hlrSccpAddress.nature=International
hlrSccpAddress.numberingPlan=ISDN
hlrSccpAddress.routingIndicator=(GT for extra/inter-PLMN, GT or SPC for intra-PLMN) default 0 (GT)
hlrSccpAddress.GTI=0100 (Global title indicator = 0100 (Global title includes translation type, numbering plan, encoding scheme and nature of address indicator)
hlrSccpAddress.type=C7
hlrSccpAddress.ssnIndicator=1 (MAP SSN always included)

imsi = RoutingInfoForSM-Res.imsi
msc-number = RoutingInfoForSM-Res.locationInfoWithLMSI.networkNode-Number
IF RoutingInfoForSM-Res.locationInfoWithLMSI.gprsNodeIndicator not present OR
(RoutingInfoForSM-Res.locationInfoWithLMSI.gprsNodeIndicator present AND
RoutingInfoForSM-Res.LocationInfoWithLMSI.additional-Number is sgsn-Number) THEN

RoutingInfoForSM-Res.locationInfoWithLMSI.networkNode-Number renamed from msc-Number between R96 and R97. The networkNode-number can also contain an sgsn-number or IP-SM-GW number or SMS Router number. |
The second step is to send the MTForwardSM:

Classify Call Scenario Feature
Description
Feature name |

|---|---|
Applicable contexts |
SS7 service |
SAS Support |
No |
Prerequisite Features |
None |
The Classify Call feature is a pre credit check feature early in the feature list (but always after the emergency number feature). The feature classifies the call’s Session Type, Roaming Indicator, and Service Type, which are stored in session state variables for future features.
Session type
The call’s session type is classified as one of:
-
MobileOriginating
-
MobileTerminating
-
MobileForwarded.
A CallType enum is defined to represent the values, and the session type is stored in session state variable CallType.
The session type is determined based on the following pseudo code:
Function DetermineSessionType(initialDP)
/* make an assumption on insufficient information that originating */
IF initialDP.eventTypeBCSM not set
THEN
return MobileOriginating
ENDIF
/* Originating or terminating eventTypeBCSM? */
IF initialDP.eventTypeBCSM is one of {origAttemptAuthorized, collectedInfo, analyzedInformation, routeSelectFailure,
oCalledPartyBusy, oNoAnswer, oAnswer, oMidCall,oDisconnect, oAbandon}
THEN
isOriginatingEventTypeBCSM = true
ELSE
isOriginatingEventTypeBCSM = false
ENDIF
IF NOT isOriginatingEventTypeBCSM
THEN
return MobileTerminating
ENDIF
IF isOriginatingEventTypeBCSM AND initialDP.redirectingPartyID is set
THEN
return MobileForwarded
ENDIF
IF isOriginatingEventTypeBCSM AND initialDP.redirectingPartyID not set
THEN
return MobileOriginating
ENDIF
return Unknown
Roaming indicator
The call’s roaming indicator is classified as one of:
-
Roaming
-
NotRoaming.
The roaming indicator is stored in session state variable RoamingIndicator as a Boolean.
The roaming indicator is determined based on the following pseudo code:
Function DetermineRoaming(initialDP)
IF initialDP.LocationInformation.VLR-Number prefix in (operator VLR number prefix list) THEN
return isNotRoaming
ELSE
return isRoaming
ENDIF
| |
In the case of an MT call, the location information may be reported; but this is dependent on an HLR setting (MAP PSI during MT processing). For MO calls, the LocationInformation relates to the calling party. For the MT case, it relates to the called party. |
The feature maintains a profile address list of home VLR numbers. If the VLR number is in this list, the call is not roaming.
Service type
The call’s service type is classified as one of:
-
Voice
-
Video
-
Data
-
Fax
A ServiceType enum is defined to represent the values, and the service type is stored in session state variable ServiceType.
The service type is determined based on the following pseudo code:
Function DetermineServiceType(initialDP)
IF initialDP.ext-basicServiceCode == ext-Teleservice THEN
CASE initialDP.ext-basicServiceCode.ext-Teleservice
Telephony(11):
EmergencyCalls(12):
VoiceGroupCall(91):
VoiceBroadcast(92):
return VOICE
Alternate speech and fax group 3(61):
Automatic fax group 3(62):
return FAX
ENDCASE
ENDIF
IF initialDP.ext-basicServiceCode is ext-BearerService THEN
IF initialDP.ext-basicServiceCode.ext-BearerService == Asynchronous data bearer services (30) THEN
return VIDEO
ELSE IF initialDP.ext-basicServiceCode.ext-BearerService == synchronous data bearer services (20) THEN
return DATA
ENDIF
ENDIF
/* assume voice if no match */
return VOICE

Closed User Group Feature
Description
Feature script name |
ClosedUserGroup |
|---|---|
Applicable contexts |
SS7 service |
SAS Support |
No |
Prerequisite features |
|
The Closed User Group (CUG) feature indicates to the OCS any CUGs that apply to the current session, and optionally restricts a subscriber to sessions within a CUG. The subscriber can be a member of multiple groups, with the group sizes being a maximum of 1,000 entries. The feature has similar functionality to the CUG Closed User Group (CUG) Supplementary Services GSM TS 02.85.
CUG will also have the following features.
-
Supports MOC, MFC, MTC, Network-Initiated.
-
If feature is enabled for the subscriber, and there is no preferential CUG and no CUG specified, then reject the session.
-
The subscriber may provide a CUG index to select which CUG will override the preferential CUG for the session.
-
Set which AVPs and CDR fields contain the CUGs that the session matches. (AVPs presumed to be set by the mapper.)
Each CUG has the following attributes:
-
Rating group
-
Incoming Access (IA) — an arrangement which allows a member of a CUG to receive calls from outside the CUG
-
Outgoing Access (OA) — an arrangement which allows a member of a CUG to place calls outside the CUG.
| |
The ICB and OCB capabilities of the CUG Supplementary Service are not supported:
Outgoing access |
The CUG to use for a call will be determined as follows:
IF CUGToUse is not set AND subscriber's CUGPreferred is set THEN CUG for call is CUGPreferred RETURN ENDIF IF CUGToUse is set but invalid index for subscriber's CUGList THEN reject call RETURN ENDIF CUG for call is CUGList[CUGToUse]
The algorithm to check if the session is within a CUG:
IF numberToCheck exact or longest prefix matches in CUG table THEN add CUG name to sessionState.CUGMatchedList list add Rating group to sessionState CUGMatchedRatingGroupList list ENDIF
The number to check include prefix matches:
| Call type | Number to check against CUG list |
|---|---|
MOC |
CalledPartyBCDNumber |
MFC |
CalledPartyNumber |
MTC |
CallingPartyNumber |
NetworkInitiated(Callback) |
Leg #4 Address |
Emergency |
N/A |
MOSMS |
DestinationSubscriberNumber |
In all cases the normalised number will be used for the check.
The CUG feature will not include any logic to determine if the CUG entries are legal. This will be the requirement of the provisioning system.
Any errors encountered during the execution of this feature, such as configuration errors or missing subscriber data, will have no effect: no tariff will be set. The call will be allowed to continue with no effect to the call. (Dependent on error — the rule above specifies rejecting the call if invalid index.)

Friends and Family Feature
Description
Feature name |
FriendsAndFamily |
|---|---|
Applicable contexts |
|
SAS Support |
No * Diameter Mediation Service |
Prerequisite features |
Subscriber Data Lookup Feature
The Friends and Family (FnF) feature sets a special OCS tariff code if a subscriber is making a call to a number in their FnF list. If the other party’s number is in the FnF list, Sentinel will send the configured FnF tariff code (=rating group) while performing charging to OCS. The subscriber for the call type will have been determined using the SS7 Subscriber Determination Feature. When the MSC triggers Sentinel, the FnF list is retrieved for the subscriber. The number to check in the FnF list for the subscriber is shown in the table below:
| Call type | Number to check against FnF list |
|---|---|
MOC |
CalledPartyBCDNumber |
MTC |
CallingPartyNumber |
MFC |
CalledPartyNumber |
NetworkInitiated(Callback) |
Leg #4 Address |
Emergency |
N/A |
MOSMS |
DestinationSubscriberNumber |
In all cases the normalized number will be used for the check.
It is expected that a subscriber’s Friends and Family list will be limited to a small number (such as 5). No logic will be implemented in the Profile/Database or Feature to enforce this limit. Any limit required by the operator will be enforced by the system provisioning the feature.
Any errors encountered during the execution of this feature, such as configuration errors or missing subscriber data, will have no effect on the call. No tariff will be set. The call will be allowed to proceed with other features.

Play Announcement Feature
The Play Announcement feature plays an announcement to the calling party during call establishment or after the called party disconnects. The announcement is played by the MSC/GMSC gsmSRF.
Description
Feature name |
PlayAnnouncement |
|---|---|
Applicable contexts |
SS7 service |
SAS Support |
No |
Prerequisite features |
|
The id of the announcements to be played is set in the AnnouncementID session variable. If the AnnouncementID session variable is not set (null) or set to 0, no announcement is played and the feature returns without error or side effect to the dialog.
Another feature must be executed prior to the PlayAnnouncement feature to set the AnnouncementID.
All announcements which are played by the feature are appended to the PlayedAnnouncementIDs session variable. This list of announcements is used by the standard CDR mappers and may be used in custom CDR mappers.
The announcement can be played using one of the following modes:
-
Using
ConnectToResourceonly, to connect to an SRF integrated with the controlling MSC. -
Using
EstablishTemporaryConnectionand an assisting dialog to connect to a non-integrated SRF. -
Using
Connectto redirect the call to an IVR or announcement device. When using this mode the call ceases to be controlled via Sentinel.
If desired the announcement mode can be configured based on address lists matching the global title digits in the dialog’s CallingPartyAddress, the triggering MSC address, the subscriber address (as determined by Sentinel), or the subscriber’s IMSI. Alternatively the announcement can always be played using the same announcement mode.

ResetTssf |
Boolean |
Indicates whether or not a ResetTimer operation will be sent before the announcement is played to reset the Tssf timer. |
InvokeTimeout |
Long |
Invoke timeout in milliseconds. In conjunction with the Tssf Reset Margin it is used to set the invoke timeout of the PlayAnnouncement operation and to determine the value to reset the Tssf timer to via the ResetTimer operation before the announcement begins (if ResetTssf is true). 1000-3600000 milliseconds. |
CtrConfig |
String |
Reference to resource configuration to use with ConnectToResource |
IvrAddressCalledPartyNumber |
The IVR address is only required if the announcement mode is CONNECT. It is specified in called party number string format, which includes comma-separated name value pairs with names one of: address, nature, numberingPlan, routingToInternalNetworkNumber. See CalledPartyNumber for more information. |
Example announcement table configuration:

The Play Announcement feature may set variables based on fields from session state (latest CCA is supported). The Sentinel XPath Language Component is used to reference fields in the CCA. For example, /MultipleServicesCreditControl[ServiceId = 0]/GrantedServiceUnit/CCTime references the amount of time granted for service with id 0.
The CtrConfig is a reference to an entry in the Resource Config table with the ConnectToResource configuration.
Resource config
| Parameter | Type | Description |
|---|---|---|
Name |
String |
Name of this CtrConfig. It is used by the announcement configuration profile to reference this configuration. |
ResourceAddressCalledPartyNumber |
The resource address in called party number string format, which includes comma-separated name value pairs with names one of: address, nature, numberingPlan, routingToInternalNetworkNumber. See CalledPartyNumber for more information. Example resource configuration profile: |
|
Name |
ResourceAddress |
srf1 |
The ResourceAddress choice NONE is selected when the ResourceAddress is not set.
Announcement mode
The announcement mode determines how the announcement will be played:
Internally using ConnectToResource only, to connect to an SRF integrated with the controlling MSC.
Using EstablishTemporaryConnection and an assisting dialog to connect to a non-integrated SRF. There are two sub-modes of this mode:
Combined mode, where the assisting MSC address, SCF id, and correlation id are all combined into the assistingSSPIPRoutingAddress parameter of the EstablishTemporaryConnection operation argument.
Separate mode, where the assisting MSC address, SCF id, and correlation id all use separate fields in the EstablishTemporaryConnection operation argument.
Using Connect to redirect the call to an IVR or announcement device. When using this mode the call ceases to be controlled via Sentinel.
The announcement mode is determined first by address list interrogation (see table below), followed by the Sentinel Selection Key configuration if no matching address list configuration was found.
Address lists
The Play Announcement feature supports four different address lists for determining the announcement mode:
| Address List Name | Default | Search Mode | Description |
|---|---|---|---|
OriginatingSccpAddressList |
longest prefix match |
Uses the the global title digits of the the incoming dialog’s CallingPartyAddress. |
MscAddressList |
longest prefix match |
Uses the address string of the MSCAddress parameter of the incoming InitialDP or InitialDPSMS. |
SubscriberAddressList |
exact match |
Uses the subscriber address for the session. |
SubscriberImsiList |
exact match |
Uses the subscriber IMSI for the session. |
The address lists actually searched by the Play Announcement feature are determined by the Sentinel Selection Key configuration. The default search mode for each list can be changed via the configuration for the corresponding address list. An address list will only be searched if the feature can determine a suitable address for the lookup. For example, if the incoming dialog has no global title digits in the CallingPartyAddress then the OriginatingSccpAddressList will not be searched, even if specified in the configuration.
Sentinel selection key configuration
Various other parameters related to playing the announcement are set in a configuration that may be scoped to the Sentinel selection key:
| Parameter | Type | Description |
|---|---|---|
AnnouncementLists |
AnnouncementList[] |
A list of Address List names specifying which address lists to search for the announcement mode. The address lists will be searched in the order given in this list. |
Default Mode |
AnnouncementMode |
The announcement mode to use if address list lookup fails to find an announcement mode. One of [INTERNAL, ETC_COMBINED, ETC_SEPARATE, CONNECT] |
Assisting SSP IP Routing Address Generic Number |
Address of the Assisting MSC. Only required if using an ETC announcement mode. |
|
Combined Mode SCF ID |
String |
The SCF ID of Sentinel to use in ETC_COMBINED mode. Only required if using an ETC_COMBINED announcement mode. |
Separate Mode SCF ID |
Byte[] |
The SCF ID of Sentinel to use in ETC_SEPARATE mode. Only required if using an ETC_SEPARATE announcement mode. |
Use Correlation Delimiter |
Boolean |
Flag indicating if a delimiter digit (hex 'b') should be used between the assisting MSC address and the SCF ID when using the ETC_COMBINED mode. Only relevant if using this mode. |
Integer |
The number of seconds added to the announcement duration used to reset the Tssf timer using the ResetTimer operation during announcement playing. This is just a safety margin. |
|
Tari Millis |
Long |
The Tari timer value in milliseconds |
Announcement playing signalling flows
If AllowDisconnect=false or is not set or has invalid value, the PlayAnnouncement.disconnectFromIPForbidden is set to true and the announcement component will send the DFC; otherwise it will not.
The call flow to be used (AllowDisconnect=true):
MSC <---- RT ----- Sentinel MSC <---- CTR ---- Sentinel MSC <---- PA ----- Sentinel MSC <- DELIMITER - Sentinel MSC ----- SRR ---> Sentinel MSC - DELIMITER -> Sentinel
The call flow to be used (AllowDisconnect=false):
MSC <---- RT ----- Sentinel MSC <---- CTR ---- Sentinel MSC <---- PA ----- Sentinel MSC <- DELIMITER - Sentinel MSC ----- SRR ---> Sentinel MSC <---- DFC ---- Sentinel MSC <- DELIMITER - Sentinel
In the case of multiple announcements, all the play announcements in the list will be sent together to the gsmSRF. The FSM will handle all of the SRR expected from the gsmSRF before returning.
The call flow to be used (all AllowDisconnect=false):
MSC <---- CTR ---- Sentinel MSC <---- PA ----- Sentinel MSC <---- PA ----- Sentinel MSC ----- SRR ---> Sentinel MSC ----- SRR ---> Sentinel MSC <---- DFC ---- Sentinel
Error handling
The Play Announcement feature may encounter a number of different errors, for example:
-
required configuration state may be missing
-
required configuration parameters may be invalid
-
operation errors sent by the initiating or assisting MSC may be encountered
In all error cases the feature returns the featureFailedToExecute result and exits. A feature script can test for this condition and react accordingly, for example the script could allow the call to continue regardless, or could release the call instead.
Examples of some error call flows:
SRR expected but not received:
MSC <---- CTR ---- Sentinel MSC <---- PA(requestAnnouncementComplete=true) ---- Sentinel Invoke timeout MSC ----> PE(NO_LINKED_RESPONSE) ---> Sentinel
This is the standard case when requestAnnouncementComplete=false (that is, no SRR expected but we still get the provider error due to the protocol definition)
MSC <---- CTR ---- Sentinel MSC <---- PA(requestAnnouncementComplete=n) ---- Sentinel Invoke timeout MSC ----> PE(NO_LINKED_RESPONSE) ---> Sentinel
Reject:
MSC <---- CTR ---- Sentinel MSC <---- PA ---- Sentinel MSC ----> PE(REMOTE_REJECT) ---> Sentinel

Release Call and Close Dialog Feature
Description
Feature name |
ReleaseCallAndCloseDialog |
|---|---|
Applicable contexts |
SS7 service |
SAS Support |
No |
Prerequisite Features |
Optional: Any feature setting the UserReleaseCause session state field |
The Release Call And Close Dialog feature is a very simple feature that instructs Sentinel to release the call or SMS and close the dialog with the MSC. The following release cause codes are used by default:
-
for calls:
-
when used during Initial Trigger handling: CLASS_1_CALL_REJECTED (21)
-
when used during End Session handling: CLASS_1_NORMAL_CALL_CLEARING (16)
-
-
for SMSes:
-
if the latest OCS reply (if any) indicates an unknown user, then: UNKNOWN_SUBSCRIBER (30)
-
otherwise: RESERVED (11)
-
If a different release cause code is needed, another feature can be run before the Release Call And Close Dialog feature to set the CCUserReleaseCause or CCUserReleaseCause session state variable. If this session state variable is set, the Release Call And Close Dialog feature uses the cause value it specifies instead of the default. If the value set is not within the valid range of cause codes, the default cause code as specified above will be used instead.

Roaming Default Call Forwarding Feature
Description
Feature name |
RoamingDefaultCallForwarding |
|---|---|
Applicable contexts |
SS7 service |
SAS Support |
No |
Prerequisite features |
Roaming Default Call Forwarding (RDCF) applies only to roaming MTC calls. It defines roaming-specific forwarding addresses for ‘Busy’, ‘No reply’ cases to prevent tromboning of forwarded calls to numbers in the subscriber’s HPLMN.
The ‘Busy’, ‘No Reply’ cases are triggered when the event report BCSM returns busy or no answer.
RDCF issues a ‘Connect’ to forward the call. The following parameters are set in the ‘Connect’:
| Parameter | Value | Description |
|---|---|---|
|

Roaming Reorigination Feature
The Reorigination feature is used as a way of handling triggers from roaming subscribers on networks that use CAPv1, or networks that use CAPv2 or CAPv3 but are otherwise determined to be unsupported for direct call control from the VPLMN.
Description
Feature name |
Reorigination |
|---|---|
Applicable contexts |
SS7 service |
SAS Support |
No |
Prerequisite Features |
The reorigination capability is needed when:
-
Roaming partners are triggering calls with CAMELv1.
-
Roaming partners are triggering calls with CAPv2, and cannot send the ERB(disconnect) in the same TCAP message as the ACR)(see CAMEL2 issue).
-
The calling party number is lost in the ISUP signalling when traversing an international carrier. In this case Sentinel must store the calling party number and set it in the connect. As setting the calling party number is not supported in CAMEL, this capability requires INAP CS1, CS2, or a proprietary variant. See Noldus[2] section 3.6.3 Short Number Dialling with CLI Guarantee pp.82. Currently not supported in Sentinel.
In these cases, the call is reoriginated to the HPLMN using a pool of special routing numbers. The reoriginated call is re-triggered from the HPLMN MSC.
The Reorigination feature should run at one of the pre credit check feature execution points for both the original InitialDP and the reoriginated InitialDP. The Reorigination feature uses the reorigination-correlation-ra to choose the special routing number, and to store data from the original InitialDP that should be correlated with the reoriginated InitialDP.
| |
See Correlation Resource Adaptor to understand how the reorigination-correlation-ra works and how it can be configured |
| |
If the dialog should not be reoriginated, or represent a reoriginated dialog, then the Reorigination feature will silently end to allow subsequent features to process the InitialDP. |
The two phases of roaming reorigination
-
Reoriginating a session. The Reorigination feature analyses the
InitialDPstored in session state to decide if it should be reoriginated. If the dialog should be reoriginated, then it chooses a free special routing address and routes the call to this special routing address. The reoriginated call may then be re-triggered from the HPLMN MSC

Below are details of the two phases, followed by Call Flow, Configuration, Configuration Profile Naming, and Provisioning Interfaces.
Phase one: reoriginating a session
Reoriginating a session includes these steps:
Determining if a dialog should be reoriginated
The Reorigination feature analyses the InitialDP to determine if the dialog should be reoriginated. The Reorigination feature checks:
-
if the dialog is for originating treatment. The first
InitialDPwill be triggered on DP2 (Collected Info). Terminating and forwarded dialogs are not reoriginated. -
if the application context is supported. Supported application contexts are:
-
cap_v1_gsmSSF_to_gsmSCF-AC
-
cap-v2-gsmSSF-to-gsmSCF-AC
-
capssf_scfGenericAC (CAP3).
-
-
if the
InitialDP VLR addressis for a roaming party for which reorigination is supported. Roaming partners that do not support theERB(Disconnect)+ACHguarantee are listed in a reorigination configuration table which includes the VLR addresses of the operator. The Reorigination service determines if the VLR address is present in the table, and if so triggers reorigination.
Processing a reoriginated session
If a session is to be reoriginated, the feature uses the Correlation RA to:
-
get an ID that is used to route the call to
-
associate some data with the correlation ID that can be used when the dialog is reoriginated.
The important steps are:
-
Create the address we will use to select an id-pool.
-
Create the data that we will associate with the correlation ID.
-
Get a new correlation entry (passing the address and correlation data).
-
Construct the outgoing connect arg.
Step one is achieved with a Mapper. The Reorigination feature looks for a mapper:
// a mapper that takes an {{InitialDP}} and generates a String.
final Mapper mapper = mapperLibrary.findMapper(selectionKey, initialDpArg.getClass(), String.class);
Sentinel includes a Mapper for this purpose — CAPInitialDPToCorrelationIdPoolAddress — that returns the MCC from location information in the InitialDP.
| |
An alternative mapper that uses a different method for choosing an address to choose the id-pool can be written using the Sentinel SDK. |
Step two is achieved with a Mapper. The Reorigination feature looks for a mapper:
// a mapper that takes an {{InitialDP}} and generates a {{byte\[\]}}.
final Mapper mapper = mapperLibrary.findMapper(selectionKey, cap1IdpArg.getClass(), byte[].class);
Sentinel includes a Mapper for this purpose, (CAPInitialDPArgToCorrelationData), that:
-
creates a new
CAP1InitialDPArgobject -
copies the called party bcd number to the new cap 1
InitialDP -
copies the bearer capability (if present) to the new cap 1
InitialDP -
copies the redirecting party ID (if present) to the new cap 1
InitialDP -
copies the redirection information (if present) to the new cap 1
InitialDP -
copies the location information (if present) to the new cap 1
InitialDP -
copies the extensions (if present) to the new cap 1
InitialDP -
uses CGIN persist factory to turn this
CAP1InitialDP → byte[].
| |
An alternative mapper that uses a different method for building the correlated data to be associated with the correlation ID can be written using the Sentinel SDK. Step four uses a configuration profile selected from the ReoriginationConfigProfileTable to construct a new DRA, and a Mapper from the trigger class (for example, Cap2InitialDPArg) to a ConnectArg, to map it to an outgoing connect arg. |
Phase two: receiving a reoriginated trigger
Receiving a reoriginated trigger includes these steps:
Determining if a dialog has been reoriginated
The reorigination feature analyses the InitialDP to determine whether the dialog is a reoriginated dialog; if:
-
The reoriginated InitialDP will be triggered on DP3 (Analyzed Info).
-
The application context is supported. Supported application contexts are:
-
cap-v2-gsmSSF-to-gsmSCF-AC
-
capssf_scfGenericAC (CAP3).
-
-
The called party is a special routing number.
| |
See Correlation Resource Adaptor to understand how the Correlation resource adaptor works and how it can be queried to see if the called party is a special routing number. |
Processing a reoriginated trigger
If this session corresponds is a reoriginated trigger:
-
use the correlation ID (the called party number) to get the correlated data from the Correlation RA
-
restore fields from the original
InitialDP(that is stored in the correlation data) into the reoriginated InitialDP.
This is achieved with a mapper. The reorigination feature looks for a mapper:
// a mapper that takes a {{byte\[\]}} and returns a {{CAP1InitialDPArg}}
final Mapper mapper = mapperLibrary.findMapper(selectionKey, byte[].class, CAP1InitialDPArg.class);
Sentinel core bundles a mapper for this purpose (CorrelationDataToCAPInitialDP) that:
-
uses CGIN persist factory to turn this byte[] into a
CAP1InitialDPArgobject -
copies the cap 1
InitialDPcalled party bcd number to the reoriginatedInitialDP -
copies the cap 1
InitialDPbearer capability (if present) to the reoriginatedInitialDP -
copies the cap 1
InitialDPredirecting party ID (if present) to the reoriginatedInitialDP -
copies the cap 1
InitialDPredirection information (if present) to the reoriginatedInitialDP -
copies the cap 1
InitialDPlocation information (if present) to the reoriginatedInitialDP -
copies the cap 1
InitialDPextensions (if present) to the reoriginatedInitialDP -
sets the
InitialDPsession state field with the updated reoriginatedInitialDP.
| |
An alternative mapper that uses a different method for reconstructing the correlated data associated with the correlation ID can be written using the Sentinel SDK. |
| |
The mapper used to reconstruct the correlated data and update the reoriginated InitialDP should be thought of as the mirror to the mapper used in step two for processing the original InitialDP. If a custom method for choosing the data to associate with the correlation ID is built with the Sentinel SDK, then two new mappers are needed that:
|
Determining service type in reoriginated dialogs
The Classify Call Scenario Feature may not be able to correctly determine that a reoriginated dialog is roaming. To ensure that the roaming indicator is set correctly, the Reorigination service must set the service type to isRoaming.

The use of the destinationSccpAddress GT information is dependent on the subscriber’s HPLMN network configuration. It is possible that some networks may not pass the GT information set in the subscriber’s o-CSI or t-CSI.
Here is an example of SCCP address routing which includes the GT information:
application context: CAP-v2-gsmSSF-to-gsmSCF-AC
CAP OpenService Type: request/indication bitmask=0x1
CapOpenArg:
{
applicationContext: 0 4 0 0 1 0 50 1

NAI=4 (international num), DIG=420603059300
}
gprsOriginatingReference: not present
gprsDestinationReference: not present
user information length: not present
}
For subscribers who are configured for intra-PLMN only, it is possible that the CSI may contain a gsmSCP address containing only PC/SSN. In this case, the feature cannot operate, as no GT information will be available.

The Set User Release Cause From Latest Event Report feature inspects the latest EventReportBCSM received by Sentinel and if possible sets the UserReleaseCause integer session state variable to a cause code value appropriate for that event report. This feature can then be followed by the Release Call and Close Dialog Feature to have that cause code included in the ReleaseCall operation sent to the MSC.
The UserReleaseCause session state variable is set depending on the eventTypeBCSM field of the latest EventReportBCSM argument:
-
for Route Select Failure:
-
if the
EventReportBCSMcontains event-specific information, then the release cause is obtained from the event-specific information; -
otherwise a default of CLASS0_NO_ROUTE_TO_DESTINATION (3) is used.
-
-
for Called Party Busy:
-
if the
EventReportBCSMcontains event-specific information, then the release cause is obtained from the event-specific information; -
otherwise a default of CLASS1_USER_BUSY (17) is used.
-
-
for No Answer:
-
a default of CLASS1_NO_ANSWER (19) is used.
-
-
for Disconnect
-
if the
EventReportBCSMcontains event-specific information, then the release cause is obtained from the event-specific information; -
otherwise a default of CLASS1_NORMAL_CALL_CLEARING (16) is used.
-
For any other case, including the absence of an EventReportBCSM operation to inspect, the UserReleaseCause session state variable is left untouched.

SIP Features
Sentinel includes many features for SIP networks, including:
-
SIP System Features — features that make up most of the default Sentinel behaviour, and can be used in feature execution pre and post scripts
-
SIP User Features — features that can be used in feature execution user scripts
These features provide the behaviour of a third party Registrar:
-
Third Party Registrar System Features — critical features that process a 3rd party REGISTER request trigger, and can be used in feature execution pre and post scripts
-
Third Party Registar User Features — features that can be used in feature execution user scripts
Registrar System Features
Sentinel includes system features for the Registrar which handle processing a Third Party REGISTER request. These features are run using system pre and post execution scripts, before and after the user features on the same execution point with the same triggering event.
-
Extract Encapsulated Request and Response — Parses the received third party REGISTER request body and extracts the 1st party REGISTER request and response
-
Extract Public and Private Identities — Analyses the 1st party REGISTER request and response and extracts public and private indentities
Extract Encapsulated Request and Response
The ExtractEncapsulatedRegisterRequestAndResponse feature parses the body of the triggering third party REGISTER request and extracts the 1st party REGISTER and response. These messages are stored as Java objects in session state fields.
| |
This feature is a critical system feature. The Registrar cannot function without this feature executing successfully. See Sentinel SIP Feature Execution Points for more about running critical features. |

Behaviour
This feature is responsible for ensuring that the public identities for the served user are present in session state. It is also responsible for refusing a REGISTER request when public identities cannot be determined.
Under normal circumstances the public identities are pulled into session state by extracting them from the P-Associated-URI header on the encapsulated first-party registration message within the third-party REGISTER request. This is done by a mapper prior to this feature running.
Initially this feature will check if the mapper was successful in extracting the public identities. If it was successful the feature will increment a statistic and complete execution with no further changes. If the mapper was unsuccessful, the feature will do one of the following:
-
If the
REGISTERrequest is for de-registration and third-party registration data is currently stored in a Cassandra database, then the feature will attempt to retrieve public identities from the most recent active registration for the served user. If this is successful the feature will populate session state with the retrieved identities and complete execution. If it is unsuccessful the feature will reject theREGISTERrequest. -
If the
REGISTERrequest is for registration or re-registration, or third-party registration data is currently stored in the HSS; then the feature will immediately reject theREGISTERrequest.
Determine Registration Action Type
This feature classifies a REGISTER request according its type (register, re-register, or de-register).
Classifying a REGISTER request
The DetermineRegistrationActionType feature examines the Contact headers of the first-party REGISTER request received in the body of the third-party REGISTER request.
A register is present if for any contact header:
-
the contact header expires parameter is present and is not zero
-
the contact header expires parameter is not present, but the request expires header is present and is not zero
A de-register is present if for any contact header:
-
the contact header expires parameter is present and zero
-
the contact header address is a wildcard and the request expires header is present and zero
-
the request expires header is present and zero and the contact header expires parameter is not present
The action that should be taken is based on the following table:
| register is present | de-register is present | have previous registration data | action |
|---|---|---|---|
false |
true |
- |
de-register |
true |
true |
- |
re-register |

Registrar Determine Network Operator
:toclevels:4 :toc-title: On this page…
This feature determines which network operator a REGISTER request is related to.
Determining the network operator
This feature adopts three techniques to determine the network operator:
-
Use the platform level default.
Special header in the third-party REGISTER request
If the REGISTER request contains a sentinel-network-operator header, then the network operator is the value of this header. For example, a REGISTER request, such as the one shown below, returns a network operator ‘HomeOneNet’.
REGISTER sip:registrar.home1.net:5060 SIP/2.0 ... From: <sip:scscf1.home1.net>;tag=m1xC8Q To: <sip:user1_public1@home1.net> ... sentinel-network-operator: HomeOneNet
If the header is present, but empty, then treat this as if there was not header present and try the next technique.
Look up the network operator in feature configuration data
This RegistrarStg:feature has configuration data that is a lookup table key → network operator. The feature uses a RegistrarStg:mapper IncomingSipRequest.class → String.class @ RegistrarMappingPoint.DetermineNetworkOperator.
The mapper included with the registrar returns the host from the To address as the lookup key. For example, a REGISTER request, such as the one shown below, results in a lookup key of ‘home1.net’.
REGISTER sip:registrar.home1.net:5060 SIP/2.0 ... From: <sip:scscf1.home1.net>;tag=CefmLQ To: <sip:user1_public1@home1.net> ...
The feature uses this lookup key to find a network operator. If there is no network operator that corresponds to this key, then try the next technique.

Configuration
This feature reads configuration from the SipSessionReplicationConfigProfileTable profile table. Profiles in this table are named based on the Sentinel selection key that they should be applied to.
The profile specification for this table is sentinel-sip-session-replication-profile. Each profile in this table has four fields that are used to indicate the point in a call that session replication should begin. Each of the four fields corresponds to a different type of leg. The fields use Enums to define the points in the call that session replication can begin. There are two different Enum types, one for legs initiated by SIP REFER or SUBSCRIBE requests, and one for legs initiated by INVITE requests.
The four fields on the profiles are:
| Field Name | Enum Type | Purpose |
|---|---|---|
InviteUASLegReplicationTrigger |
InviteReplicationTrigger |
Determines the point in the signalling on a |
InviteUACLegReplicationTrigger |
InviteReplicationTrigger |
Determines the point in the signalling on a |
SubscriptionUASLegReplicationTrigger |
SubscriptionReplicationTrigger |
Determines the point in the signalling on a |
SubscriptionUASLegReplicationTrigger |
SubscriptionReplicationTrigger |
Determines the point in the signalling on a |
The possible values for each of the two different Enum types are outlined below.
InviteReplicationTrigger Enum
| Enum Value | Description |
|---|---|
DISABLED |
Replication is prevented for this leg. All upstream and downstream legs in the same session are also excluded from replication. |
NOOP |
No replication decision will be made by this leg, see partner trigger (UAC/UAS) for subsequent replication behaviour. |
INITIAL_REQUEST |
Replication will begin as soon an initial INVITE request is seen on a leg of this type. |
PROVISIONAL_RESPONSE |
Replication will begin as a 18x response for the initial INVITE request is seen on a leg of this type. |
RINGING_RESPONSE |
Replication will begin when a 180 response for the initial INVITE request is seen on a leg of this type. |
SUCCESS_RESPONSE |
Replication will begin when a 2xx response for the initial INVITE request is seen on a leg of this type. |
ACK |
Replication will begin when an ACK for a 2xx response for the initial INVITE request is seen on a leg of this type. |
SubscriptionReplicationTrigger Enum
| Enum Value | Description |
|---|---|
DISABLED |
Replication is prevented for this leg. All upstream and downstream legs in the same session are also excluded from replication. |
NOOP |
No replication decision will be made by this leg, see partner trigger (UAC/UAS) for subsequent replication behaviour. |
INITIAL_REQUEST |
Replication will begin as soon an initial SUBSCRIBE or REFER request is seen on a leg of this type. |
SUCCESS_RESPONSE |
Replication will begin when a 2xx response for the initial SUBSCRIBE or REFER request is seen on a leg of this type. |
Behaviour
This feature reads configuration data from the SipSessionReplicationConfigProfileTable profile table, and uses it to set up triggers in the SIP service that will initiate session replication. When reading from the profile table, the feature will select the profile that best matches the current Sentinel selection key.
The feature sets the triggers by setting special session state fields that are checked by the Sentinel SIP service when it hits key points in a call flow. If the service decides it has reached or passed the point in the call the the trigger corresponds to, it will instruct the Sentinel SIP Leg Manager to begin session tracking on all current and future legs (See External Session Tracking for details of how legs are tracked).
If all legs in a session are configured NOOP Rhino will initiate persistence automatically after the session reaches maxPersistDeferredTransactionAge.
If the feature is unable to find any suitable profile for the current session, it will not set any triggers. This effectively disables session replication for the session.
| |
If either UAC or UAS legs are set to DISABLED, a later execution point cannot then enable replication. IE. it is an error to set InviteUACLegReplicationTrigger to DISABLED and InviteUASLegReplicationTrigger to ACK |
Special Handling for Initial Request Triggers
There is special handling in the feature for user-agent-server legs that have an INITIAL_REQUEST trigger. If InviteUASLegReplicationTrigger config is set to INITIAL_REQUEST and the feature was triggered on an INVITE request, or SubscriptionUASLegReplicationTrigger config is set to INITIAL_REQUEST and the feature was triggered on an SUBSCRIBER or REFER request, then the feature itself will immediately instruct the Leg Manager to begin session tracking, bypassing the need to wait for the service to do it.
Session Ownership Facility Availability
Before it attempts to read any configuration the feature will check whether the Rhino Session Ownership Facility is available on the node. If the feature determines that the session ownership facility is not available, it will skip loading config, and disable session replication for the session.
External Session Tracking
This feature creates and maintains records in the Rhino Session Ownership Facility for all SIP legs that have been flagged for tracking.

Behaviour
This feature monitors all legs in a session, regularly checking if any of the legs require a session ownership record, and if so, what information should be stored in that record. The feature maintains its own list of which legs currently have records in the session ownership facility, and when those records were last updated.
The exact behaviour of the feature differs based on how it is invoked:
-
If the feature is invoked at the
SipEndSessionfeature execution point, it will execute End Session Clean-Up behaviour. -
If it is invoked at any other feature execution point, it will execute Leg Tracking behaviour, followed by Charging Instance Tracking behaviour.
-
If the feature is invoked with a
SessionOwnershipWriteResultEventvia the Session Ownership Event Handler, it will execute Result Processing behaviour.
Session Ownership Records for protocol dialogs
Session ownership records are used to track information about specific sessions across multiple Rhino nodes. Their main purpose it to indicate which node is currently responsible for processing a session, but they can also be used for other information that Sentinel features might need to keep track of across nodes. They are stored the in Rhino Session Ownership Facility.
Sentinel SIP has the capability to maintain zero or one session ownership records for a SIP leg, and zero or one session ownership records for an Ro Dialog. Session ownership records are not maintained for all legs at all times, instead individual legs can be flagged for tracking in the session ownership facility. When that flag is seen by this feature, it will create a session ownership record for the leg. The flag can be set by the Sentinel SIP service when session replication is triggered, or by user features that need a leg to be tracked for their own purposes.
If the Sentinel Session has an Ro dialog, and at least one SIP leg is tracked, then the Ro session is tracked.
All protocol dialog session ownership records created, or updated by this feature are linked to the Sentinel Session’s Convergence Name Session Ownership Record. This ensures that after a fail-over, any simultaneous signalling will resolve to a single node.
Fields on a SIP Dialog Session Ownership Record
Certain fields on the Sentinel SIP Leg API are used to populate associated fields on a session ownership record. The following table outlines the relationship between data stored using the Leg API, and data stored on a session ownership record.
| Session Ownership Record Field | Corresponding Leg API Getter | Corresponding Leg API Setter | Notes |
|---|---|---|---|
PrimaryKey |

N/A |
The primary key cannot be modified and is always based on the SIP Dialog ID associated with the leg. |

The dialog ID of a leg is used as the primary key for the session ownership record. This means that if the dialog ID changes (e.g. when the dialog is confirmed by the remote party) a new record is created and the old one is deleted.
There are a few other SIP Leg API calls that relate to Session Ownership Records: - setTrackingEnabled() and isTrackingEnabled() are used set and read the flag that determines whether a session ownership record will be created for a leg. - setWaitForTrackingResultEnabled() and `isWaitForTrackingResultEnabled() are used to set and read a flag that affects how this feature manages asynchronous queries to the session ownership facility (see below). - getLastTrackingDataChangeTime() provides the timestamp of the last time that a call to any of: setTrackingEnabled(), setOwner(), setAdditionalTrackingKeys(), or setAdditionalTrackedAttributes() on the Leg API actually resulted in a meaningful change in the leg’s tracked state.
Fields on a Ro Dialog Session Ownership Record
Certain fields on the Sentinel SIP ChargingInstance API are used to populate associated fields on a session ownership record. The following table outlines the relationship between data stored using the ChargingInstance API, and data stored on a session ownership record.
| Session Ownership Record Field | Corresponding ChargingInstance API Getter | Corresponding CharingInstance API Setter | Notes |
|---|---|---|---|

The primary key cannot be modified and always includes the Ro session identifer. |

While the owner can be modified by other features, it should generally be left to this feature to set it. |
Leg Tracking
When the feature is invoked to do standard tracking behaviour, it will get the set of current legs from the leg manager and iterate over it. For each leg in the set, the feature will go through the following steps:
-
Check if the leg is flagged for tracking.
-
If it is not it will skip the remaining steps and move on to the next leg.
-
If it is flagged for tracking, the feature will move on to the next step.
-
-
Check if there is already a session ownership record stored under the leg’s Dialog ID.
-
If not, the feature will create a new record and write it into the session ownership facility. The remaining steps will then be skipped and the feature will move on to the next leg.
-
If so, it will move on to the next step.
-
-
Check if the owner node in the record matches the node currently executing the feature.
-
If not, a fail-over has occurred and the feature will take ownership of the leg (using
Leg.setOwner()), and write an updated record into the session ownership facility (indicating that the owning node is the currently executing node). Then skip the remaining steps and move on to the next leg.
-
-
Check when the tracked data on the leg was last modified against the last time that the session ownership record was updated.
-
If the leg’s tracked data has been modified since the last time the session ownership record was updated, then the feature will create and write an updated record into the session ownership facility. It will then skip the remaining step and move on to the next leg.
-
-
Check whether the record’s TTL could expire before the feature is next invoked.
-
If so, then the existing record will be rewritten into the session ownership facility with a refreshed TTL.
-
Otherwise the feature will move on to the next leg.
-
After processing all of the legs, the feature will look for any records it has stored under Dialog IDs that no longer correspond to any leg that has tracking enabled. If it finds any such records, it will delete them from the facility.
All store and delete requests sent to the session ownership facility are executed asynchronously. The value of isWaitForTrackingResultEnabled() on the Leg API will affect the feature’s behaviour while it waits for the result for requests relating to that leg’s session ownership record. If any leg that has an outstanding store request to session ownership facility returns true for that API call, the feature will enter a featureWaiting state while it has nothing to do. This will prevent the session plan advancing to the next feature while the session ownership request is in progress. This is useful if further down the session plan, there is a feature that requires the session ownership record to be in place. If all legs with outstanding requests return false, then the feature will enter the featureHasFinished state while it waits, and session processing will continue in the mean time. The feature will not normally enter the featureWaiting state for delete requests.
This means that the feature can block further SIP signalling progress until a write has either succeeded, failed or timed out on a per-leg basis. There are several application specific use-cases where the database state (behind the session ownership facility) must be visible before further SIP signalling proceeds.
Charging Instance Tracking
When the feature is invoked to do standard tracking behaviour, it first checks if any SIP legs are tracked and if so it checks if a Charging instance exists and is not in the Final state. This essentially means that if Diameter Ro charging is in-use, and Session Replication is enabled, then the Ro session is tracked.
The feature goes through the following steps to determine if the Charging Instance (Ro Session) should be tracked:
-
Check if there is already a session ownership record stored under the Ro Dialog’s tracking key (this is a value that includes the Ro session identifier)
-
If not, the feature will create a new record and write it into the session ownership facility, and further steps are skipped
-
-
Check if the owning node in the record matches the node currently executing the feature.
-
If not, a fail-over has occurred, and the feature writes an updated record indicating that the owning node is the currently executing node. Further steps are skipped.
-
-
Check when the tracked data on the Charging Instance was last modified against the last time that the session ownership record was updated. If an update is needed the feature updates the record in the session ownership facility and skips the remaining steps.
-
Check whether the record’s TTL could expire before the feature is next invoked. If so the existing record is rewritten into the session ownership facility with a refreshed TTL.
All store and delete requests sent to the session ownership facility are executed asynchronously. The feature does not enter a waiting state for a Charging Instance’s session tracking write response (success, failure or timeout).
Result Processing
When a result is received from the session ownership facility, the feature simply records statistics and logs messages based on whether the result is successful, partially successful, or unsuccessful. After processing the result, the feature will decide to enter a featureWaiting or featureHasFinished state based on the same criteria used in Leg Tracking behaviour.
End Session Clean-Up
When the feature is triggered at session end, it create delete requests for all remaining session ownership records associated with the session. While under normal circumstances, the feature would not enter the featureWaiting state for delete requests, during end session behaviour the feature will keep going into the featureWaiting state until ALL outstanding requests are answered. This prevents to session from ending until all records have been handled.
AVP CDR Feature
SipAvpCdr is a system feature that is responsible for building a Call Detail Record that reflects the actions taken whilst processing a session.
SipAvpCdr runs once when a session is ending and creates a CDR based on information gathered from session state, and then writes it out using the cdr-ra.

Pre- and post-features
The B2BUA ECUR pre- and post-features cover event charging using a reserve/confirm model. The features are responsible for:
-
creating the reservation charging instance (
B2BUAChargingFeatureUtil.DEFAULT_ECUR_CHARGING_INSTANCE) and default session counter on an initial SUBSCRIBE, MESSAGE, OPTIONS, or PUBLISH request -
performing the initial credit check
-
detection of message delivery or nondelivery conditions and credit finalisation.
The general use case is that a message will be B2BUA’d through Sentinel. The ECUR pre-feature will request a credit check, then allow delivery of the message. When a response to the B2BUA’d message is received, the credit reservation will be confirmed (or refunded).

Charging API interactions
The charging API interactions fall under the following categories:
-
charging instructions issued on the
B2BUAChargingFeatureUtil.DEFAULT_ECUR_CHARGING_INSTANCEitself -
updates made to all counters on the charging instance, mainly limited to updates from CCAs and credit finalisation
-
complete implementation of event based charging on the default counter.
Interaction with the default charging instance
Interaction with the default charging instance includes bxref#:initialisation[initialisation], bxref#initial-and-update-credit-checks[checks for initialisation and updates], and bxref#:finalisation[finalisation].
Initialisation
When the pre-feature is first triggered on an incoming event request, it creates the default ECUR charging instance, under the name B2BUAChargingFeatureUtil.B2BUA_ECUR_CHARGING_INSTANCE. It then maps the initial request to a session counter address written to the session state field B2BUAChargingCounterAddress. This is the default session counter on which all ECUR based charging is performed.
Initial and update credit checks
On any trigger other than an incoming chargeable event request, both features check whether the B2BUAChargingFeatureUtil.DEFAULT_ECUR_CHARGING_INSTANCE has been initialised. The first step is to check the instance exists in the ChargingManager, then that the instance has a session counter with the address specified in session state B2BUAChargingCounterAddress. If either check fails, the feature ends immediately on the assumption that ECUR is not enabled.
The pre-feature will issue a credit reservation for an incoming chargeable event request. The called party leg is suspended until the OCS authorises the call.
Interaction with all session counters
When a CCA is received, all counters on the ChargingInstance will be processed according to the algorithm outlined in Counter Update Algorithm Pseudo Code.
If a credit finalisation is raised, the post-feature will clear the pending requested units on all session counters.
When charging using a non-default counter, another feature will need to set reported used and pending requested units on the counters as needed.
Interaction with the default session counter
The default ECUR session counter is fully managed by the ECUR pre- and post-features. Generally speaking, user features need not interact directly with this counter.
Mappers
This feature uses two mappers:
-
The first converts the initial SIP request to SessionCounterAddress.
The default implementation is SipRequestToSessionCounterAddress:// a mapper that takes a {{SipRequest}} and generates a {{SessionCounterAddress}}. final Mapper<SentinelSipSessionState> mapper = getMapperLibrary().findMapper( getSessionState().getSentinelSelectionKey(), SipRequest.class, SessionCounterAddress.class, mappingPoint); -
The second mapper converts a CCA into a list of session counters.
The default implementation is CCAtoSessionCounterList:// a mapper that takes a {{CreditControlAnswer}} and generates a {{List<SessionCounter>}}. final Mapper<SentinelSipSessionState> mapper = getMapperLibrary().findMapper( getSessionState().getSentinelSelectionKey(), CreditControlAnswer.class, List.class mappingPoint);

Behaviour
Basic Behaviour
The B2BUA feature divides the communication channel into two legs and mediates all SIP signaling between both ends of the session.
On receipt of an initial SIP request (i.e. a request without a To tag), the feature creates an outgoing leg, links it to the triggering leg, and forwards an equivalent request on the new leg. The forwarded request will have a new call ID unless the feature has been specifically configured to preserve the call ID across the B2BUA. If the initial request is received on a leg that is already linked to another leg, the feature will not create a new leg or attempt to forward the message on the existing leg. If another feature ends the session before the B2BUA feature processes the initial request, a new leg will not be created and the request will not be forwarded.
For all other incoming SIP messages the feature adds an equivalent outgoing SIP message to the linked leg’s message queue. If there in no leg linked to the triggering leg, the feature will not attempt to forward the message.
| |
This feature is a critical system feature, many features rely on the functionality and success of this feature, including the B2BUA SCUR, B2BUA ECUR, B2BUA IEC, and SDP Comparison features. See Sentinel SIP Feature Execution Points for more about running critical features. |
Early ACKs
If configured to do so, on an incoming success response to an initial INVITE, the feature will send an early ACK on the triggering leg, and will subsequently not forward the ACK received on the linked leg. An early ACK will not be sent if SDP negotiation has not been completed (offer & answer).
Error Responses
There are a number of cases where the feature will generate and send an error response for an inbound request instead of forwarding the request:
-
When the feature forwards a request on a linked leg, it will decrement the value of the
Max-Forwardsheader on the outbound request. If the value reaches 0, the feature will generate and send a 483 (Too Many Hops) response. -
If the feature receives a request and is unable to forward it on the linked leg due a to a SIP transaction already being in progress on that leg, it will send a 491 (Request Pending) response.
-
If an internal error occurs that prevents the request from being forwarded, the feature will send a 500 (Server Internal Error) response.

The B2BUA IEC pre and post features cover event charging using a charge/refund model. The features are responsible for:

instructing the charging manager to send a direct debit to the OCS
-
detection of message nondelivery conditions and refunding as necessary
The general use case is that a chargeable message — a SUBSCRIBE, MESSAGE, OPTIONS, or PUBLISH — will be B2BUA’d through Sentinel. The IEC post feature will trigger a direct debit, then allow delivery of the message. If a response to the B2BUA’d message is received which indicates non-delivery, the amount debited will be refunded.
For a high level overview of Sentinel charging see Sentinel SIP Charging Architecture
| |
During any credit check, Sentinel automatically ensures all incoming messages are queued in the SLEE until the CCA (or a timeout) is received; in other words, no further network events will be delivered to Sentinel or processed until the credit check is complete. Currently, Sentinel for SIP only supports one charging instance per Sentinel session, though this instance may have multiple session counters. |

All of Sentinel for SIP’s charging features make use of Sentinel’s comprehensive charging API — see Using the SIP Charging Manager |

Interaction with the default charging instance
Initialisation
When the pre-feature is first triggered on an incoming event request, it creates the default IEC charging instance, under the name B2BUAChargingFeatureUtil.B2BUA_IEC_CHARGING_INSTANCE. It then maps the initial event request to a session counter address written to the session state field B2BUAChargingCounterAddress. This is the default session counter on which all IEC based charging is performed.
Initial debit
On any trigger other than an incoming chargeable event request, both features check whether the B2BUAChargingFeatureUtil.DEFAULT_IEC_CHARGING_INSTANCE has been initialised. The first step is to check the instance exists in the ChargingManager, then that the instance has a session counter with the address specified in session state B2BUAChargingCounterAddress. If either check fails, the feature ends immediately on the assumption that IEC is not enabled.
The pre feature will instruct the charging instance to send a direct debit message to the OCS.
The post feature will set the pending requested units and suspend the called party leg until the OCS authorises the call.
Interaction with all session counters
When a CCA is received, all counters on the ChargingInstance will be processed according to the algorithm outlined in Counter Update Algorithm Pseudo Code. The pre feature will clear the pending requested units on all session counters.
When charging using a non-default counter, another feature will need to set reported used and pending requested units on the counters as needed.
Interaction with the default session counter
The default IEC session counter is fully managed by the IEC pre and post features. Generally speaking, user features need not interact directly with this counter.
Setting pending requested units on the default counter
When the post feature is triggered on a chargable event, the pending requested units will be set to the value of RequestUnitsServiceSpecific in session state, unless they have already been set to a non-zero value. If the pending requested units value is non-zero, it will not be overwritten.
Mappers
This feature uses two mappers:
-
The first converts the initial SIP request to a SessionCounterAddress.
The default implementation is SipRequestToSessionCounterAddress:// a mapper that takes a {{SipRequest}} and generates a {{SessionCounterAddress}}. final Mapper<SentinelSipSessionState> mapper = getMapperLibrary().findMapper( getSessionState().getSentinelSelectionKey(), SipRequest.class, SessionCounterAddress.class, mappingPoint); -
The second mapper converts a CCA into a list of session counters.
The default implementation is CCAtoSessionCounterList:// a mapper that takes a {{CreditControlAnswer}} and generates a {{List<SessionCounter>}}. final Mapper<SentinelSipSessionState> mapper = getMapperLibrary().findMapper( getSessionState().getSentinelSelectionKey(), CreditControlAnswer.class, List.class mappingPoint);
B2BUA SCUR Features
The SIP B2BUA SCUR Pre and Post features define default session charging behaviour for Sentinel SIP as a B2BUA.
Overview
At a high level, the supported behaviour covers time-based session charging:
-
creating the reservation charging instance (
B2BUAChargingFeatureUtil.DEFAULT_SCUR_CHARGING_INSTANCE) and default session counter on an initial request -
initial credit check
-
recurring credit re-authorisation and used unit reporting at regular intervals
-
responding to
ReAuthRequestsfrom an OCS or the Sentinel Diameter Mediation layer -
detection of session end conditions and credit finalisation.
The SCUR features can also be used in conjunction with other reservation charging features such as SDP Comparison and MMTel Adhoc Conference. The SCUR features automatically handle accounting by updating session counters and the charging timer. The charging timer is armed redundantly if the session is replicated.
User features wishing to enhance Sentinel’s SCUR behaviour might be concerned with:

During any credit check, Sentinel automatically ensures all incoming messages are queued in the SLEE until the CCA (or a timeout) is received; that is, no further network events will be delivered to Sentinel and processed until the credit check is complete. Currently, Sentinel SIP only supports one charging instance per Sentinel session, though this instance may have multiple session counters. |
All Sentinel SIP’s charging features make use of the Sentinel SIP Charging Architecture.

Charging API interactions
The charging API interactions fall under the following categories:
-
charging instructions issued on the
B2BUAChargingFeatureUtil.DEFAULT_SCUR_CHARGING_INSTANCEitself -
updates made to all counters (which may or may not be time-based) on the charging instance, mainly limited to updates from CCAs and credit finalisation
-
complete implementation of time-based charging on the default counter.
Interaction with the default charging instance
Initialisation
When the pre feature is first triggered on an initial incoming request, it creates the default SCUR charging instance, under the name B2BUAChargingFeatureUtil.B2BUA_SCUR_CHARGING_INSTANCE. It then maps the initial request to a session counter address written to the session state field B2BUAChargingCounterAddress. This is the default session counter on which all time-based charging is performed.
In a scenario with no initial incoming request, it is necessary for some user feature, such as the SIP Third Party Charging Feature, to initialize the charging instance and default session counter.
Initial and update credit checks
On any trigger other than an initial incoming request, both features check whether the B2BUAChargingFeatureUtil.DEFAULT_SCUR_CHARGING_INSTANCE has been initialised. The first step is to check the instance exists in the ChargingManager, and then that the instance has a session counter with the address specified in session state B2BUAChargingCounterAddress. If either check fails, the feature ends immediately on the assumption that SCUR is not enabled.
The pre feature will issue a credit reservation:
-
On an initial SIP request
-
On expiry of the charging timer (
QUOTA_EXHAUSTED) -
Or receipt of an RAR
If the Final-Units-Indicator AVP was present in the previous CCA then a credit reservation will not occur, legManager.endSession() is called and a CCR-T is sent.
If a reservation was requested on the charging instance and there are no previous SIP requests on the calling party linked leg (in other words, the called party), the post feature treats it as an initial credit check. Therefore, the called party leg is suspended until the OCS authorises the call.
Interaction with all session counters
When a CCA is received, all counters on the ChargingInstance will be processed according to the algorithm outlined in Counter Update Algorithm Pseudo Code.
If a credit finalisation is raised, the post feature will clear the pending requested units on all session counters.
When charging using a non-default counter, another feature will need to set reported used and pending requested units on the counters as needed.
Interaction with the default session counter
The default SCUR session counter is fully managed by the SCUR pre and post features. Generally speaking, user features need not interact directly with this counter.
Setting end time on the default counter
When the post feature detects credit finalisation is raised, it sets the default counter’s end time to the current system time.
Setting reported units on the default counter
If either charging instruction is raised, the reported used units will be set on the default counter and the SCUR charging timer will be cancelled.
Setting start time on the default counter
On an incoming initial invite ACK, the pre feature records the current time as the start time on the default counter. In a third-party scenario the initial invite ACK is outgoing, so the start time is recorded when the CallEstablished session state field is true and the charging timer ID is null.
Setting pending requested units on the default counter
If a reservation instruction was issued by the user or pre features, and pending requested is 0, it will be set to the value of RequestUnitsSeconds in session state.
Setting reported used units on the default counter
If a finalisation or reservation instruction is issued, the post feature sets reported used units on the default counter. It uses the utility method in B2BUAChargingFeatureUtil.setReportedUsedMillis, which simply deducts the cumulative committed units from the current chargeable time.

Mappers
This feature uses two mappers:
-
The first converts the initial SIP request to SessionCounterAddress. The default implementation is SipRequestToSessionCounterAddress
// a mapper that takes a {{SipRequest}} and generates a {{SessionCounterAddress}}. final Mapper<SentinelSipSessionState> mapper = getMapperLibrary().findMapper( getSessionState().getSentinelSelectionKey(), SipRequest.class, SessionCounterAddress.class, mappingPoint); -
The second mapper converts a CCA into a list of session counters. The default implementation is CCAtoSessionCounterList:
// a mapper that takes a {{CreditControlAnswer}} and generates a {{List<SessionCounter>}}. final Mapper<SentinelSipSessionState> mapper = getMapperLibrary().findMapper( getSessionState().getSentinelSelectionKey(), CreditControlAnswer.class, List.class mappingPoint);
Determine Cause Code Feature
The Determine Cause Code feature is responsible for determining an appropriate value for the Cause-Code AVP in the IMS-Information AVP used in Diameter charging. It does this by monitoring an ongoing dialog looking for any event that could bring the dialog to an end. It selects an appropriate code based on what kind of dialog ending event it finds.

Session state inputs and outputs
Behaviour
The DetermineCauseCode feature detects and classifies conditions that would bring about the end of a dialog. The feature runs at the end of every execution point to allow it detect any end of dialog cause. When it executes, the feature will start by determining the type of dialog based on what SIP Request method was used to initiate the dialog. From there, the feature will look for all possible conditions that could bring the dialog to an end. Finally, if the dialog is determined to be ending, a cause code value will be selected based on what condition triggered it and that value will be set in the DiameterCauseCode session state field.
This table summarises the possible cause code values, details of how they are determined follow on below.
| Code | Meaning |
|---|---|
|
Dialog was terminated with a SIP 3xx response. The actual value of the code will match the response status. |
|
Dialog was terminated with a SIP 2xx response. The actual value of the code will match the response status. |
|
Subscription dialog ended normally. |
|
Transaction dialog ended normally. |
|
Invite session ended normally. |
|
Invite session setup failed. |
|
There was an internal error in Sentinel and no other code can be determined. |
|
Dialog was terminated with a SIP 4xx response. The actual value of the code will match the response status. |
|
Dialog was terminated with a SIP 5xx response. The actual value of the code will match the response status. |
|
Dialog was terminated with a SIP 6xx response. The actual value of the code will match the response status. |
Dialog Classification
The feature classifies the dialog into one of three categories: subscriptions, transactions, and invite sessions. It does this classification by examining the initial execution point that the feature was triggered on, which corresponds to the method of the SIP request the initiated the SIP dialog, as follows:
| Execution Point | Type | Initial Request Method |
|---|---|---|
|
Invite Session |
|
|
Invite Session |
|
|
Subscription |
|
|
Transaction |
|
Note that the feature does not support REGISTER dialogs.
End of Dialog Detection
The procedures for detecting an ending dialog depends on the dialog type. The detailed procedures for each dialog type are laid out below. Note that a cause code value of 3 will occur any time an internal error prevents the feature from determining a more accurate code.
Transaction Dialogs
When evaluating a transaction dialog, the feature will proceed through the following checks until one results in a cause code value being found and stored in the DiameterCauseCode session state field. If none of the checks produce a cause code then the dialog is considered to be still in progress and session state will not be modified.
-
Check if the session ender was explicitly invoked to terminate the dialog. If this is the case, then the cause code will match the SIP response status code that was provided to the session ender.
-
Check if the calling leg has already been released by the leg manager. If this has happened, one of two things can happen:
-
If a cause code had previously been determined in an earlier run of the feature, that code will be preserved.
-
If no cause code has been determined, then
-1(Successful transaction) will be used.
-
-
Check for a pending final response queued to be sent on the calling leg, if one is found a code will be selected as follows:
-
If the response status is
200 OKthen a code of-1(Successful transaction) will be used. -
For any other final response, the response status will be used.
-
Subscription Dialogs
When evaluating a subscription dialog, the feature will proceed through the following checks until one results in a cause code value being found and stored in the DiameterCauseCode session state field. If none of the checks produce a cause code then the dialog is considered to be still in progress and session state will not be modified.
-
Check if the session ender was explicitly invoked to terminate the dialog. If this is the case, then the cause code will match the SIP response status code that was provided to the session ender.
-
Check if the calling leg has already been released by the leg manager. If this has happened, one of two things can happen:
-
If a cause code had previously been determined in an earlier run of the feature, that code will be preserved.
-
If no cause code has been determined, then
-2(End of subscribe dialog) will be used.
-
-
Check if the most recently received
SUBSCRIBErequest has aExpiresheader with the value0. If this is the case, then-2(End of subscribe dialog) will be used. -
Check for a final response the most recent
SUBSCRIBErequest (regardless of whether it has been sent or is queued) that has a status that is greater than or equal to300. If one is found then the response status will be used as the cause code.
Invite Sessions
For invite sessions, the feature does an additional classification to determine what state the session is in: setup, mid-session, or ending. This classification is made based on the current execution point, and on whether an ACK for the initial INVITE/200 transaction has been sent or received by Sentinel.
For sessions in the setup phase, the feature will proceed through the following checks until one results in a cause code value being found and stored in the DiameterCauseCode session state field. If none of the checks produce a cause code then the dialog is considered to be still in progress and session state will not be modified.
-
Check if the session ender was explicitly invoked to terminate the dialog. If this is the case, then the cause code will match the SIP response status code that was provided to the session ender.
-
Check if the calling leg has already been released by the leg manager. If this has happened, one of two things can happen:
-
If a cause code had previously been determined in an earlier run of the feature, that code will be preserved.
-
If no cause code has been determined, then
2(Unsuccessful session setup) will be used.
-
-
Check if a SIP
BYErequest has been sent or received, or is queued to be sent on the calling party leg. If this is the case, then2(Unsuccessful session setup) will be used. -
Check for a final response to the initial
INVITErequest (regardless of whether it has been sent or is queued) that has a status that is greater than or equal to300. If one is found then the response status will be used as the cause code.
For sessions in the mid-session phase, the DiameterCauseCode session state field will be immediately set to 0 (Normal end of session) as this is guaranteed from this point.
For session in the ending phase will check if a cause code has been determined in an earlier run of the feature. If one has been, nothing will change. If there is no cause code, then 0 (Normal end of session) will be set in the DiameterCauseCode session state field.

Behaviour
When triggered this feature will attempt to retrieve a profile from the DetermineChargingConfigProfileTable using the current Sentinel Selection Key. If it fails to find a profile, the feature ends without doing anything.
If a profile is found, the values for DisableCharging, InterimCdrsEnabled, SessionCdrsEnabled, and ContinueCallOnOCSFailure are mapped directly from their profile fields to their equivalent session output fields. The effect of each field is outlined below.
Charging Enabled/Disabled
The DisableCharging field controls whether online charging should be enabled for the session. When it is set to true the following behaviour is executed:
-
All reservation charging instances in the Charging Manager will be finalised.
-
The
MonitorCallOnlysession output field will be set totrue.
When the MonitorCallOnly session state field is true, feature execution scripts will skip over online charging features.
Interim CDRs
The InterimCdrsEnabled field controls whether interim CDRs will be written for a session. This is done by checking the value of the field in feature executions scripts, and only executing the Interim CDR Feature if it is true.
Session CDRs
The SessionCdrsEnabled field controls whether a session CDR will be written when a session ends. This is done by checking the value of the field in feature executions scripts, and only executing the appropriate AVP CDR feature if it is true.
In Sentinel Express deployments this affects execution of the AVP CDR Feature. In Sentinel VoLTE deployments this affects execution of the VoLTE SIP AVP CDR Feature.
Continue Call On OCS Failure
The ContinueCallOnOCSFailure field determines system behaviour when there is a problem communicating with the OCS. When it is set to true the call will be allowed to continue in the event of an OCS failure, however:
-
No further online charging will occur for the session, even if communication with the OCS is re-established.
-
Rf and CDRs will continue to track the session.
-
OCS failure for a conference call will still result in the session ending (except for mid-session failures).

Behaviour
The DiameterPerLegInfo feature populates the Diameter Ro IMS-Information AVPs with information about the call which is specific to each leg. Information about the call as a whole is populated by the Diameter Service Info feature. The information is gathered on a per-leg basis where it is specific to a given SIP leg. Such values are recorded into session state maps keyed by leg name. The feature needs to be run in two separate modes at different phases of each execution point. The inbound mode should be invoked in the SIP system pre scripts to process the incoming trigger leg, while the outbound mode should be invoked in the post scripts to monitor outgoing messages on all SIP legs. The feature stores the IMS-Information AVPs in session state, and updates it at various feature execution points when other features have run. The resulting AVPs are used by the AVP CDR Feature feature when writing a CDR. The AVPs are also sent in Credit-Control-Requests to the OCS.

The DiameterServiceInfo feature populates the Diameter Ro IMS-Information AVPs with information about the call as a whole. Information specific to individual legs is stored by the Diameter Per Leg Info feature. The feature stores the IMS-Information AVPs in session state, and updates it at various feature execution points when other features have run. The resulting AVPs are used by the AVP CDR Feature feature when writing a CDR. The AVPs are also sent in Credit-Control-Requests to the OCS.

Behaviour
MCC and MNC
The ExtractNetworkInfo feature parses P-Access-Network-Info (PANI) and P-Visited-Network-Identifier (PVNI) headers found in the SIP trigger or Registration Records to determine the Mobile Country Code (MCC) and Mobile Network Code (MNC) for the subscriber. The following OpenCloud extension AVPs are used to communicate MCC and MNC information in CDRs and CCRs:
-
OC-ACCESS-NETWORK-MCC-MNC -
OC-VISITED-NETWORK-MCC-MNC -
OC-IMSI-NETWORK-MCC-MNC
Priority is given to any headers present in the SIP trigger, if they are able to be parsed. In Mobile Terminating cases OC-Term-P-Access-Network and OC-Term-P-Visited-Network headers added by SCC during reorigination are used if present. For any given header type, if it is missing or invalid in the SIP trigger, the feature will then check registration records. When an MNC cannot be determined, but the MCC was able to be extracted, a value of "000" will be used in place of the missing MNC.
For information on Sentinel AVP definitions, please refer to Sentinel AVPs in the Sentinel Administration guide.
ISO Country Code
The ExtractNetworkInfo feature parses P-Access-Network-Info (PANI) and P-Visited-Network-Identifier (PVNI) headers found in the SIP trigger or Registration Records to determine the ISO Country Code for the subscriber and populates the IsoCountryCode session state field. The section below explains precedence:

Configuration
When parsing MNC’s from digit strings (such as an IMSI), the MobileCountryCodeInformation profile table is used to determine whether the MNC is two or three digits. The table maps an MCC to a list of that country’s MNC’s which are then compared against the digit string to determine length. At present, other fields are for administrative use only.
| Parameter | Type | Description |
|---|---|---|
MCC |
String |
The three digit Mobile Country Code each profile represents. |
MNCs |
String[] |
An ordered list of the two or three digit Mobile Network Codes for this MCC. |
Country |
String |
The name of the country the MCC belongs to (for documentation purposes only.) |
CountryDialCode |
String |
A digit string representing the actual dial code for this country. |
ISOCountryCode |

The feature is provisioned using the Sentinel Features REST API or web interface.
Interim CDR Feature
SipInterimCdr is a system feature that is responsible for writing interim Call Detail Records and/or Diameter Accounting Requests (ACRs) throughout the session.
SipInterimCdr runs at various key points throughout a session and if any of its write conditions are met it writes either or both of:
-
an interim AVP CDR using the
cdr-ra -
an ACR using the
rf-control-ra
Interim AVP CDRs and Diameter Accounting Records (ACRs) have substantially similar content and the same triggering logic hence both are supported by this feature.
The feature maintains a timer for the interim CDR period. This timer may be adjusted according to the Rf accounting interval provided by the CDF. The interim CDR timer is armed redundantly if session replication is enabled.

Functionality
This feature can be configured to:
-
write CDRs to the local filesystem (through the
cdr-ra), and/or -
write ACRs using the Diameter Rf protocol (through the
rf-control-ra)
This feature uses the information from the session state fields mentioned above and constructs a CDR and/or ACR for output. See AVP CDR Format for the format of the CDRs.
Although the feature runs in many execution points, it inspects various session state fields to decide whether or not to write an interim CDR and/or ACR.
An interim CDR and/or ACR will be written under any of the following conditions:
-
On the initial SIP request on the 'LegForCdrs'
-
On the
SipInterimCdrfeature timer, if no CDR has been recently written -
On session end
-
When a feature (e.g. SDP Monitor) sets
WriteCdrOnSDPChangeto true
When the feature is about to write an INTERIM or STOP ACR for a Sentinel Session, if checks if the current Rhino node has an Rf Control Activity for the Diameter Rf session. If it does not, a new Rf Control Activity is started using the same Rf session identifier. This fails over the Rf session.
Also see Charging Information for general information about the contents of CDRs, ACRs and CCRs.

This feature only supports writing binary CDRs. If the cdr-ra is configured to write text CDRs the feature will fail to execute. |

Max Call Duration Feature
| |
This feature is deprecated as of version 2.8.0.3 of Sentinel SIP. Its functionality is now handled by the Session Refresh Feature. |
The Max Call Duration Feature monitors the call duration and terminates the call if the maximum call time has been exceeded.
On an incoming initial ACK or when the callEstablished session state field is true, a timer is set. The timer length is controlled by the MaxTimerInterval and MaxCallDuration parameters in the feature’s configuration. MaxCallDuration can be overridden with a session state value to enable unlimited call duration or a session specific max call duration. A feature should override the MaxCallDuration in the initial call setup phase not during mid-call. On the expiry of the timer, the feature checks the call time against the maximum call duration. If the maximum call time has been exceeded, LegManager.endSession is instructed. If not, then the timer is reset to the minimum of MaxTimerInterval and the remaining MaxCallDuration.

Behaviour
The feature needs to be run in two separate modes at different phases of each execution point. The inbound mode should be invoked in the SIP system pre scripts to process the incoming trigger leg. In inbound mode, it verifies that it was triggered by an initial request, or the final response to such a request. If neither of these conditions is met, the feature will finish execution without modifying any state. In outbound mode, it checks outgoing messages on all SIP legs. If it detects an initial request, the feature will record the current system time into the PerLegInitialRequestTimeMillis session state field against the corresponding leg name, increment the associated statistic, and then finish execution. If it detects a final response, the feature will record the current system time into the FinalResponseTimeMillis session state field and increment the associated statistic.
Remove Headers From Outgoing Messages Feature
The RemoveHeadersFromOutgoingMessages feature performs removal of headers from outgoing messages based on configuration.
Behavior
The RemoveHeadersFromOutgoingMessages works as follows:
-
For any SIP message present on a leg’s SipMessageQueue any header matching an entry in the
HeadersToRemoveFromOutgoingMessagesconfiguration will be removed. -
For any SIP message present on a leg’s SipMessageQueue any
Supportedheader value matching an entry in theSupportedHeaderValuesToToRemoveFromOutgoingMessagesconfiguration will be removed.
| |
In order to capture all outgoing SIP messages this feature should be the last feature to run in If configured this feature will modify the content of any outgoing message with a matching header or See Sentinel SIP Feature Execution Points for more information. |

Behaviour
This feature tracks changes in SDPs used to negotiate media streams, and triggers credit re-authorization if material changes have occurred. Materialness is determined by classifying the codec specified in the SDP into 'equivalence classes' (see Configuration).
If the difference between the previous and newly negotiated SDP is material from a rating condition perspective, then the feature will perform a client-initiated credit re-authorization towards the Online Charging System (OCS). The OCS will be notified that the reason is due to rating conditions changing. While the re-authorization is in progress, the outgoing message is suspended. On successful response from the OCS, the outbound message processing is resumed.
If the difference between the previous and newly negotiated SDP is immaterial, then no credit re-authorization will be performed. On session refresh, where the new SDP matches the previously negotiated SDP, no credit re-authorization will be performed.
If a codec is not mapped to an equivalence class, it will trigger a re-authorization when compared to any codec which does belong to a class. Two codecs, neither of which are mapped to a class, are consided equivalent and will not trigger a re-authorization. Another way to think of this is to consider that all codecs not specifically mapped are essentially mapped to their own class.
The following diagram gives some examples:

Mappers
This feature uses two mappers:
-
The first is used to map an SDP match model to an SDP match model that has been adapted to contain code equivalence lookups. The default implementation is SdpMatchModelToSdpCcrMatchModelMapper
// a mapper that takes a {{SDPMatchModel}} and generates a {{SDPMatchModel}}. final Mapper<SentinelSipSessionState> mapper = getMapperLibrary().findMapper( getSessionState().getSentinelSelectionKey(), matchModel.getClass(), SdpMatchModel.class, mappingPoint); -
The second mapper takes a DiffModel representing the total differences of two SDP and filters it to only show those differences relative to charging. The default implementation is SdpDiffToSdpCcrDiffMapper
// a mapper that takes a {{SDPDiffModel}} and generates a {{SDPDiffModel}}. final Mapper<SentinelSipSessionState> mapper = getMapperLibrary().findMapper( getSessionState().getSentinelSelectionKey(), arg.getClass(), SdpDiffModel.class, mappingPoint);
Configuration
The default configuration recognizes three equivalence classes - Audio8KHzSingleChannel, Audio16KHzSingleChannel, and Video90KHzSingleChannel. The codecs mapping to each class are as follows:
Equivalence Class |
EncodingName/ClockRate/Channels |
|---|---|
Audio8KHzSingleChannel |
G726-40/8000/1 |
Audio16KHzSingleChannel |
DVI4/16000/1 |

MPV/90000/1 |
See SDP Comparison for Rating Condition Change Determination for details of configuring the SDP comparison.
SDP Monitor Feature
The SDP Monitor system feature keeps track of all Session Description Protocol (SDP) offers and answers on a leg.
It works like this:
-
When an SDP offer is received, the feature updates the leg’s
latestReceivedSDP,previousReceivedSDPandlatestReceivedSDPSequenceNumberand waits for the corresponding answer. -
When the corresponding SDP answer is sent, the feature updates the leg’s
latestSentSDP,previousSentSDPandlatestSentSDPSequenceNumber. -
If the offer/answer exchange is successful the current
committedSDPbecomes thepreviousCommittedSDPand the leg’scommittedSDPis set to the latest sent SDP on the leg. ThecommittedSDPSequenceNumberis set to the latest SDP sequence number. -
If the offer/answer exchange is unsuccessful, the previous
committedSDPandcommittedSDPSequenceNumbervalue(s) (if any) are restored. At which point the feature waits for a new SDP offer and the offer/answer exchange continues.
The feature also maintains an SDP field specifying the exchange initiator. The field is used by the Diameter Service Info Feature feature to set the Media-Initiator-Flag AVP in charging requests. Other features can access the SDP information using the Sentinel SIP Leg API.

Behaviour
When a feature requires SDP conflict management, it can call SdpRewriting.startSdpRewritingForLegs() to start an SDP rewriting association between a pair of legs. This association is persisted in session state, and includes rules for rewriting SDP sent in either direction, so that conflicts are avoided. The SDP Rewriter feature then examines SDP message bodies on all messages sent on these legs, and rewrites the SDP as appropriate. If either party updates their session description, this feature updates its rewriting rules for the legs, so that changes are propagated correctly to the other party.
For more details see SDP conflict management.

The SDP Rewriter feature must run as a post-system feature on all execution points, to ensure that messages containing SDP sent by other features can be rewritten before transmission. The feature must run before the SDP Monitor feature, so that SDP Monitor sees the updated SDP, if present. |

SIP Downstream Forking Feature
What is downstream forking?
Downstream forking occurs when something downstream (e.g. S-CSCF) of the application (Sentinel) decides to fork a call (e.g a result of subscriber registration data). A downstream call branch to each destination will be created. All 1XX(with the exception of 100) and 2XX responses must be forwarded upstream and the first final response forwarded will result in all remaining forks with active transactions being terminated using the CANCEL method.
It is possible for one or more additional 200 OKs to arrive whilst the CANCEL is still being processed, in this event these will also be forwarded upstream. In the event this happens, 3GPP TS 24.229 states the UE should ACK the additional 200 OKs and follow immediately with a BYE.
Call flows

|---|---|
Applicable contexts |
SIP service |

Prerequisite Features |
None |
The SipDownstreamForking feature handles a SIP call forked downstream by the S-CSCF, an application, or other UAS. This feature must be triggered on every early response and request until the call has been setup.
For each new downstream forked leg (dialog) response, the feature will import the leg into the Sentinel SIP Service and if the original INVITE was received upstream, the feature will forward the response on a new upstream leg (dialog) which is created by the feature and linked with the downstream leg. Subsequent early dialog messages on these legs will be be ignored by this feature but handled in the default way by the Sentinel SIP Service until a final response is received.
When the feature receives a final response, it will detach all other downstream legs and their linked upstream legs from the Service, delegating responsibility to the SIP SIS RA to clean up these remaining dialogs. In the crossover case where a CANCEL is received from the Calling Party and a Called Party forked leg answers, the forked leg that answered will be released (resulting in a BYE request sent).
| |
Regardless of which leg sends the final error response, the SIP SIS RA will always send it the initial calling party leg. |
-
The imported downstream fork legs will have the following leg name format:
downstreamfork[unique session id]. -
The created upstream fork legs will have the following leg name format:
upstreamfork[unique session id].
The feature should be installed in the SipAccess_PartyRequest and as the first feature in the SipAccess_PartyResponse. It cannot be run in any other execution points.
Feature interaction
First response on a new forked dialog
The first response on a new forked dialog is delivered by the SIP SIS RA on the activity which sent the INVITE request. Subsequent responses are delivered on the leg created by this feature activity.
If another feature is also using this first response it will be necessary to determine the correct leg as follows:
Leg actualResponseLeg = legManager.getLeg(response.getSipSession());
The leg will only differ from the leg associated with the INVITE dialog if the response.isForked() returns true.
Sequential Forked SDP Mediation
The Sequential Forked SDP Mediation Feature is used to mediate 183 and 2xx messages into UPDATE’s if multiple 183 messages with SDP content have been received due to a sequential fork.
The first 183 is sent through unchanged. When a subsequent 183 message or 2xx with SDP is received the feature will transform this into an UPDATE to be sent upstream. If a 2xx with SDP is mediated to an UPDATE, a 2xx without SDP is sent to the upstream party once the UPDATE has been responded to by the upstream party.
The one change that is made to the SDP is the session version number in the origin line, the feature ensures this value is always bigger than the previously sent version number if the SDP has changed.
The feature also runs on mid session messages such as a re-INVITE from downstream to ensure that the upstream party always receives SDP origin session version numbers that are bigger than have been previously sent if the SDP has changed.
If while an unreliable 183 is being mediated, a 2xx with SDP is received then the 2xx with SDP is cached until the UPDATE triggered by unreliable 183 is responded to and the 2xx is then mediated.
The Feature configuration allows users to change the behaviour of the feature. The default setting is ALLOWS_UPDATE, this means the feature will look at the allow header of the INVITE message to determine whether or not the UE supports UPDATE messages. If there is no UPDATE value present then the messages will simply be passed on, but if the INVITE did contain UPDATE in its allow list then any subsequent 183’s and 2xx with SDP will be changed into UPDATE messages. The other values of this config override the allow header, if set to ON then the feature will ignore the allow list and always behave as if the UE supports UPDATE messages. If OFF then the feature will not change 183’s or 2xx’s to UPDATEs.

Provisioning interfaces
The feature is provisioned using the Sentinel Features REST API or web interface.
Behaviour
On an incoming initial ACK or when the callEstablished session state field is true, a repeating timer is set. The timer’s period is specified by the TimerInterval value in the feature’s configuration. This timer is armed redundantly if the session is replicated. The number of repetitions will be so such that the timer will stop firing soon after the maximum call duration is reached.
Each time the timer fires, the feature first checks if the maximum call duration has been exceeded. If the max call duration has been exceeded, the feature will end the session. If not, Leg.refreshSession is instructed on each leg using the RefreshPeriod from the feature’s configuration. The RefreshPeriod represents the period of no activity before a refresh request should occur. If no messages have been sent or received on a leg within the RefreshPeriod, a refresh request transaction will be initiated.
Refresh requests are by default re-INVITE requests. The Session Refresh feature can be configured using the RefreshWithUpdateIfAllowed configuration to use UPDATE requests instead. If an endpoint did not include the UPDATE method in it’s Allows header then the RefreshWithUpdateIfAllowed configuration is ignored.
| |
RFC 6141 describes this process in SIP INVITE dialogs. This will cause all legs to be refreshed immediately. |
Receipt of a Re-Auth-Request on the Ro interface
RFC 4005 (https://tools.ietf.org/html/rfc4005#page-13) states:
A Diameter server may initiate a re-authentication and/or re- authorization service for a particular session by issuing a Re-Auth- Request (RAR) message [BASE].
For example, for pre-paid services, the Diameter server that originally authorized a session may need some confirmation that the user is still using the services.
If a NAS receives an RAR message with Session-Id equal to a currently active session and a Re-Auth-Type that includes authentication, it MUST initiate a re-authentication toward the user, if the service supports this particular feature.
Therefore when receiving a RAR, Sentinel responds with an RAA, initiates a Credit Control Update Request (CCR-U) and triggers this feature. This means that one or more SIP dialog refreshes run in parallel to the CCR-U. If the session refresh is successful then no further action is necessary. However if SIP dialog refreshes are not successful then Sentinel will move to the End Session point-in-session, thereby sending a CCR-T.
Additionally when the Validity-Time timer expires, Sentinel acts as though a RAR was received.
Store Header Info Feature
The StoreHeaderInfo feature is responsible for extracting information from incoming SIP requests that is relevant for charging purposes. It looks at and records information relevant for charging purposes, specifically from the Contact, Call-ID, P-Charging-Vector, and P-Access-Network headers on SIP requests and responses received from the served user. It records information from the P-Early-Media, Allow, and Contact headers relevant to access transfer procedures.

Behaviour
The StoreHeaderInfo feature runs whenever a SIP request or response is received by Sentinel. Initially the feature examines which leg the message was received on to determine whether the message came from the served user (i.e. the calling party on the originating instance, and the called party on a terminating instance). If the message was not received from the served user, the feature will not attempt to modify headers related to charging. If the message was received from the served user, the feature will attempt to extract charging information from the message headers as described below. Other headers are examined in all cases, regardless of served leg. Once it has done this, the feature will finish execution.
P-Access-Network-Info Header
If the P-Access-Network-Info header is present on the message, it will be recorded in the headersByLeg session state field. If the active leg already had a value for this header, it will be updated.
| |
3GPP TS 24.229 (Release 8 and later) permits multiple |
P-Charging-Vector Header
If the P-Charging-Vector header is present, then the feature will attempt to extract several pieces of information:
-
The value of the
icid-valuewill be taken and stored in theIMSChargingIdsession state field. -
If the
term-ioiparameter is present, its value will be taken and stored in theTerminatingInterOperatorIdentifiersession state field. -
If the
orig-ioiparameter is present, its value will be taken and stored in theOriginatingInterOperatorIdentifiersession state field. -
If any additional charging identifier parameters are present, one will be taken and stored in the
ChargingIdentifiersession state field.-
Any of the following parameters can be used:
gcid,dslcid,bcid,itc-id, orecid. -
If no additional charging identifiers are found, the
icid-valuewill be used for theChargingIdentifier.
-
Contact Header
If there is a +sip.instance parameter on the Contact header of the incoming message, the feature will look at its value and attempt to extract a valid IMEI from it. If an IMEI is found, it will be taken and stored in the IMEI session state field.
Call-ID
The value of the Call-ID header is used as an identifier for the session in Diameter charging. So, the value of this header will be taken and stored in the UserSessionId session state field.
P-Early-Media Header
If the P-Early-Media header is present, the header value will be recorded for the triggering leg in the headersByLeg session state field.
Subscribe Downstream Forking Feature
The Subscribe Downstream Forking Feature manages the additional SIP legs that can result from forked subscriptions.
-
When Sentinel sends or forwards an initial SUBSCRIBE, a downstream proxy may fork the request to several targets.
-
Each target that accepts the SUBSCRIBE will send an initial NOTIFY back to Sentinel.
-
The first NOTIFY to arrive is associated with the original downstream leg, and will automatically be forwarded upstream by the B2BUA Feature if it previously forwarded the SUBSCRIBE .
-
If additional NOTIFYs arrive as a result of a fork, then the
SubscribeDownstreamForkingfeature is needed to determine how to handle them. -
Each additional NOTIFY potentially creates a new SIP dialog, or leg in Sentinel.
-
If the event package (determined by the NOTIFY
Event:header) does not support forking, then theSubscribeDownstreamForkingfeature automatically rejects the NOTIFY with a 481 response, and no new leg is created. -
If the event package does support forking, then the
SubscribeDownstreamForkingfeature creates new downstream and upstream legs, and schedules the NOTIFY to be forwarded upstream. The new upstream and downstream legs are linked, and subsequent requests on these legs will be handled by the B2BUA Feature. -
The names of event packages that are known to support forking are configured as per [forking-event-packages-configuration].

If an event package happens to be an event template package (such as winfo above), all event packages that derive from it are handled automatically. So the fictional package foo.winfo will automatically support forking because winfo does.
Additional event packages may be added as standards evolve, or to support proprietary events.

B2BUA Subscription Activity Guard Feature
The B2BUA Subscription Activity Guard feature tracks outstanding subscriptions and invalidates sessions which have not been correctly shut down.
The B2BUA Subscription activity guard feature is used to protect against servers not correctly terminating their subscriptions. For each non-terminating notify that is B2BUAed by Sentinel, this feature starts a timer which fires after the expiration of the notify. If another notify for the same subscription is received, the timer is updated. If a terminating notify is sent, the timer is cleared and removed. If the timer fires, this shows that a terminating notify has not been sent by the server. In this case, the feature invalidates and detaches from both legs of the call, freeing resources and cleaning up as appropriate.

Behaviour
The call’s session type is classified as one of:
-
MobileOriginating -
MobileTerminating -
MobileForwarded
A CallType enum is defined to represent the values, and the session type is stored in session state variable CallType.
The feature uses either one of two headers on an incoming SIP request to determine the call type: P-Served-User and Route. The P-Served-User header is the preferred source of information. The Route header is only checked if the call type cannot be determined from the P-Served-User header.
P-Served-User Header
There are two parameters of interest on the P-Served-User header.
The first is a valueless orig-cdiv parameter, if this is present the call type will be classified as MobileForwarded. Otherwise, the feature will look for the sescase parameter, the value of that parameter will determine the call type as follows:
| Parameter Value | Resulting Call Type |
|---|---|
|
|
|
|
|
|
If none of these parameters or values are present, the feature will check the Route header instead.
Route Header
The feature always looks at the top-most route header of the incoming message. It will look for the following valueless parameters on the header to determine the call type:
| Parameter Name | Resulting Call Type |
|---|---|
|
|
|
|
|
|
If none of these parameters or values are present, the feature will use the default call type: MobileTerminating.
Additional Call Forwarding Detection
When a parameter on the P-Served-User or Route header indicates the call type is MobileOriginating and the AdditionalCallForwardingDetection config option is set to true, the feature will execute additional checks to determine if the call has been forwarded.
There two additional checks, one on the Request-URI the other on the History-Info header. The call type will be determined to be MobileForwarded if either one of the following conditions are met:
-
The
Request-URIhas acauseparameter with one of the following values:302,404,408,480,486,487,503. -
There is a
History-Infoheader present on the request.
If neither condition is met, the call type will be determined to be MobileOriginating.

Behaviour
The feature is triggered by any incoming SIP response received during call setup.
Before attempting to play an announcement, the feature will check that a number of conditions have been met:
-
No other announcement is in progress or has been queued to play.
-
The incoming response is a 4xx, 5xx, or 6xx response to an initial INVITE request.
-
The response was received on a leg that is linked to another leg.
-
A response with the same status code has been queued to be sent on the linked leg.
-
No other error code announcement has been played by a downstream node on the same network.
If any of these conditions are not met, the feature will finish execution without attempting to play an announcement.
If the conditions are met, then the feature will check the ErrorCodeAnnouncementMappingTable for a profile that matches both the status code of the incoming response, and the current Sentinel selection key. If no such profile is found the feature will look for a profile labelled DEFAULT (while still matching the selection key).
If a profile is found using either method, and it indicates that an announcement should be played (i.e. the profile has a non-zero AnnouncementID); then the feature will queue an announcement with the indicated AnnouncementID. The feature will also give an instruction to terminate the call after the announcement has been played. Depending on the value of the EndCallWith487Response field on the profile, the status code of the response used to terminate the call will either be 487, or the code from the original incoming response.
In the event no profile is found, the feature will finish execution without queuing an announcement.
The SIP Play Announcement Feature is responsible for actually playing the announcement.
Suppression Of Repeat Announcements
The feature uses a custom SIP header (OC-Error-Code-Announced) to prevent multiple error code announcements being played in the same call by different AS instances.
When the feature is invoked on an incoming error response it will check for the presence of this header on the response. If it is present, the feature will not attempt to play an error code announcement.
When the feature does play an announcement, it will add this header to the outbound final error response that is sent after the announcement is complete. The header value indicates the original error code that triggered the announcement (even when the actual response status code is changed to 487).
This header should be stripped before it leaves the network, therefore multiple error code announcements could still be played if some legs of the call are not in the same network.

Details
Feature script name |
SipMidCallPlayAnnouncement |
|---|---|
Applicable contexts |
SIP service |
SAS Support |
Yes |
Prerequisite Features |
Any feature setting the MidCallAnnouncementInfoQueue session state field and any feature that sets the LanguageConfig session state field, like Sip Set Language Feature feature. |
Typical feature execution points |
SipAccess_ServiceTimer, SipAccess_PartyResponse, SipMidSession_PartyRequest, SipMidSession_PartyResponse, and any other mid-session execution point where an announcement may be desired, such as SipMidSession_CreditLimitReached. |
Timer usage |
Execution-point targeted timer will trigger the feature at the SipAccess_ServiceTimer execution point on expiry. |
Behaviour
The announcements are played by the MRF. The announcements to play are queued in the MidCallAnnouncementInfoQueue session state as SipAnnouncementInformation objects each with an announcement ID. The announcement may have an associated language otherwise the LanguageConfig session variable is used. If the MidCallAnnouncementInfoQueue is empty or null then the MidCallAnnouncementID session variable is used. If the MidCallAnnouncementID session variable is not set, the MidCallAnnouncementQueue is checked. If the MidCallAnnouncementQueue is empty or null then the feature returns without error or side effect to the dialog.
Another feature must be executed prior to the SipMidCallPlayAnnouncement feature to set the LanguageConfig and the MidcallAnnouncementId or queue.
All announcements which are played by the feature are appended to the PlayedAnnouncementIDs session state variable. This list of announcements is used by the standard CDR mappers and may be used in custom CDR mappers.
The LanguageConfig String is a language code in RFC 3066 format. Use of the LanguageConfig session state field is optional. The feature will search for a profile using the LanguageConfig and MidcallAnnouncementId as keys. If the feature can’t find a profile for the specified language, it will search for a profile just using the MidcallAnnouncementId.
If there are multiple announcements scheduled in the MidCallAnnouncementInfoQueue, each announcement will be attempted on a new MRF dialog when each previous announcement completes (whether or not it played successfully). Each subsequent announcement necessitates sending another Re-INVITE to the calling party. If the MRF times out at any point, the MRF session will be torn down appropriately and the call will proceed as normal including queued announcements (or be ended, as in the above scenario).
Passive Party Media
The feature supports multiple options for how the passive party’s media streams should be handled while the announcement is playing to the active party. The option to use is specified per-announcement on the SipAnnouncementInformation object by whatever queued the announcement. There are three possibilities, they are:
-
NO_HOLD: The passive party is not put on hold during the announcement, media streams are left as they were. -
BLACK_HOLE_ONLY: SDP is renegotiated with the passive party so that for the duration of the announcement, all media streams are directed to a black hole IP. -
FULL_HOLD: SDP is renegotiated with the passive party so that for the duration of the announcement, all media streams are directed to a black hole IP; and additionally the passive party is put on hold by setting the stream status tosendonlyorinactive. This is the default.
Call flows
Mid-call low-credit announcement
In this scenario, a feature installed in SipAccess_CreditAllocatedPostCC analyzes the CCA-U and determines that the charged party has low credit. The feature script then runs the MidCallPlayAnnouncement feature. Points of interest are highlighted and explained below the diagram.
Request from PlayedParty arrives while waiting for answer to PassiveParty hold INVITE
In this scenario, the PlayedParty sends an INVITE or an UPDATE while Sentinel is waiting for the PassiveParty to respond to the hold INVITE. The request is rejected and the announcement is set up as normal.
PassiveParty does not accept being put on hold
The feature will simply end the announcement and allow the session to continue.
MRS unresponsive after initial provisional response
When the INVITE request is sent to MRS, Sentinel receives a provisional 100 Trying response which cancels the SIP-Stack-internal request timeout timer; however, no further response is received. Sentinel fires its own ‘noResponse’ timer which ultimately times out. The PlayAnnouncement feature handles the timer event (the feature must be installed in the SipAccess_ServiceTimer execution point) and sends a CANCEL to MRS. The leg is subsequently released. The PAShouldEndSessionWhenFinished session state field indicates whether the feature should send endSession to the core or not. The call may continue afterwards.
Resume call during announcement
For this call flow to work, the Interruptable flag is set to true in the announcement configuration. This tells the feature that the announcement can be stopped by either the call being resumed by the passive party for hold cases, or the call ended if the passive party was to end it with a BYE. A call is put on hold with a long-running announcement. When the holding party resumes the call, a feature detects the resume request and sets the RequestIsResume session state field. When the announcement feature runs and sees this, as well as the interruptable flag, it will stop the announcement and re-connect the two parties for the call to proceed.

SIP Play Announcement Feature
The SipPlayAnnouncement feature plays a queue of announcements to the calling party during call establishment.
Description
Feature script name |
SipPlayAnnouncement |
|---|---|
Applicable contexts |
SIP service |
SAS Support |
Yes |
Prerequisite features |
Any feature setting the EarlyMediaAnnouncementInfoQueue session state field and any feature that sets the LanguageConfig session state field, like Sip Set Language Feature feature. |
Typical feature execution points |
SipAccess_PartyResponse, SipAccess_PartyRequest, SipMidSession_PartyResponse, SipMidSession_PartyRequest, SipAccess_ServiceTimer, and any SipAccess execution points where an announcement may be triggered, such as SipAccess_SubscriberCheck. |
Timer usage |
Execution-point targeted timer will trigger the feature at the SipAccess_ServiceTimer execution point on expiry. |
The announcement is played by the MRF. The announcements to play are queued in the EarlyMediaAnnouncementInfoQueue session state as SipAnnouncementInformation objects each with an announcement ID. The announcement may have an associated language otherwise the LanguageConfig session variable is used. If the EarlyMediaAnnouncementInfoQueue is empty or null then the AnnouncementID session variable is used. If the AnnouncementID session variable is not set, the EarlyMediaAnnouncementQueue is checked. If the EarlyMediaAnnouncementQueue is empty or null then the feature returns without error or side effect to the dialog.
Another feature must be executed prior to the SipPlayAnnouncement feature to set the EarlyMediaAnnouncementInfoQueue and the LanguageConfig.
All announcements which are played by the feature are appended to the PlayedAnnouncementIDs session state variable. This list of announcements is used by the standard CDR mappers and may be used in custom CDR mappers.
The LanguageConfig String is a language code in RFC 3066 format. Use of the LanguageConfig session state field is optional. The feature will search for a profile using the LanguageConfig and AnnouncementID as keys. If the feature can’t find a profile for the specified language, it will search for a profile just using the AnnouncementID as key.
The SipPlayAnnouncement feature supports UE preconditions if present.
Example Callflows
Play Announcement without Preconditions - OCS Rejects Call
In this scenario, the CCA-I returns with result code 4012 (credit limit reached); and a feature setting the EndSessionAfterAnnouncement session state field to a non-zero value is installed in the SipAccess_CreditLimitReached execution point and runs before PlayAnnouncement, which is also installed in the same execution point. B-Party is never contacted.
The MRF dialog is similar for other types of pre-call announcements, including successful calls.
If the A-Party cancels at any point, the MRF SIP dialog will be torn down appropriately. If there are multiple announcements scheduled (eg the AnnouncementID field has been set as well as at least one entry in the queue, or simply multiple entries in the queue), each announcement will be attempted on a new MRF dialog when each previous announcement completes (whether or not it played successfully). Each subsequent announcement necessitates sending another 183 to the calling party, which will be translated to an UPDATE as needed by the Sequential Forked SDP Mediation feature. If the MRF times out at any point, the MRF session will be torn down appropriately and the call will proceed as normal including queued announcements (or be ended, as in the above scenario).
Early media play announcement with preconditions and VoWiFi
In this scenario, the caller has resources available as the bearer is WiFi, so there is no value in resource reservation from the caller’s perspective.
Preconditions are in use in case the terminating party does not have resources available at INVITE time. However in this call flow the terminating party is the MRF which does have resources available.
The initial INVITE from the UE will contain these media attributes related to QoS.
a=sendrecv a=curr:qos local sendrecv a=curr:qos remote none a=des:qos mandatory local sendrecv a=des:qos none remote sendrecv
The 183 from the TAS towards the UE will not contain a conf line like this
a=conf:qos remote sendrecv
If in the initial INVITE the UE includes P-Early-Media: supported then the TAS must insert the P-Early-Media: sendrecv header in the 183 response.
This is because some devices includes a P-Early-Media: supported header in the initial INVITE and some MRFs do not include it in the 183 response. Some devices will not play early media unless they receive the P-Early-Media header in the 183 response.
Early media play announcement with preconditions and VoLTE
This case differs from the WiFi case as LTE allows the use of radio resource reservation.
Therefore the INVITE from A indicates that the current state is inactive.
The MRF already has resources available.
The initial INVITE from the UE will contain these media attributes related to QoS.
a=inactive a=curr:qos local none a=curr:qos remote none a=des:qos mandatory local sendrecv a=des:qos none remote sendrecv
The 183 from the MRF will contain a conf line like this, instructing A to UPDATE when its resources are available
a=conf:qos remote sendrecv
If in the initial INVITE the UE includes P-Early-Media: supported then the TAS must insert the P-Early-Media: sendrecv header in the 183 response sent upstream. This is because some devices include a P-Early-Media: supported header in the initial INVITE and some MRFs do not include it in the 183 response. Some devices will not play early media unless they receive the P-Early-Media header in the 183 response.

SIP Short Code Feature
Description
Feature name |
SipShortCode |
|---|---|
Applicable contexts |
SIP service |
SAS Support |
Yes |
Prerequisite features |
The Short Code feature is a pre-credit check feature that performs number translation of short-codes in the request-URI of the received INVITE request. If the request-URI does include a short-code, then SipShortCode updates the request-URI and To addresses in the received INVITE, using a short-code translation table.
| |
The SipShortCode feature will only do analysis if:
Addresses may contain the digits allowed in a global phone number as per RFC 2806. |
If the number is in international format and is prefixed by the home country code then the prefix will be removed before performing analysis. The feature makes use of the Normalization Component to remove the prefix.
If the number is in international format and is not prefixed by the home country code then no analysis will be performed.
Sentinel has a configurable short-code address list, scoped by the Sentinel selection key, which is used for this digit analysis. If a short-code matches an address in the request-URI, then both the request-URI and the To address are updated with a translated address (that corresponds to the short-code).

Prerequisite features |
DetermineCallType |
The Subscriber Determination feature is a pre credit check feature early in the feature list (but always after the emergency number feature). The feature inspects the SIP INVITE to determine the subscriber address for this session and set the Subscriber session state field.
It determines the subscriber address either by:
-
returning the value already stored in the Subscriber session state field; otherwise
-
returning the value of the P-Served-User header (if that header is present); otherwise
-
analysing the FROM or RequestURI headers, depending on the call type:
-
moc: subscriber address is the URI in the FROM header
-
mtc: subscriber address is the URI in the RequestURI header
-
networkinitiated: subscriber address is the URI in the FROM header
-
The feature will string the parameters from the URIs in case some is present.

Processing HTTP requests
The SIP Service accepts HTTP requests in the following format:
http://<host>:<port>/sentinel-sip?subscriber=447408800855&cgpn=642200001&cdpn=642200002
The feature checks for presence of the subscriber, cgpn, and cdpn request parameters. If all parameters are available, the feature creates the suspended legs with the initial INVITE messages, according to the parameters from the HTTP request and feature configuration. The legs after creation are suspended and linked.
If the feature is being used in an uncharged scenario, it should run in the SipThirdPartyAccess_SubscriberCheck script in order to trigger the sending of an HTTP 200 (callIsBeingSetup) response without waiting for a CCA. In a charged scenario, it should not run in SipThirdPartyAccess_SubscriberCheck, to ensure that it waits for a success CCA before sending the response. See Configuration for an example of configuring the script to cover both cases.

Mappers
This feature uses three mappers:
-
The first two are used to map HTTP requests to outgoing SipRequests, as determined by the mapper execution point. The default implementations are HttpRequestToCallingPartySipRequest:
// a mapper that takes a {{HttpRequest}} and generates a {{SipRequest}}. final Mapper<SentinelSipSessionState> mapper = getMapperLibrary().findMapper( getSessionState().getSentinelSelectionKey(), HttpRequest.class, SipRequest.class, SipMappingPoint.CallingPartySipRequest );// a mapper that takes a {{HttpRequest}} and generates a {{SipRequest}}. final Mapper<SentinelSipSessionState> mapper = getMapperLibrary().findMapper( getSessionState().getSentinelSelectionKey(), HttpRequest.class, SipRequest.class, SipMappingPoint.CalledPartySipRequest ); -
The third mapper maps a SipThirdPartyCallOutcomes to a HTTP response The default implementation is SdpDiffToSdpCcrDiffMapper:
// a mapper that takes a {{SipThirdPartyCallOutcomes}} and generates a {{HttpResponse}}. final Mapper<SentinelSipSessionState> mapper = getMapperLibrary().findMapper( getSessionState().getSentinelSelectionKey(), SipThirdPartyCallOutcomes.class, HttpResponse.class, mappingPoint);
Configuration
To support both charged and uncharged calls, the SipThirdPartyAccess_SubscriberCheck script should be configured as follows:
featurescript SipThirdPartyAccessSubscriberCheck {
...
if not session.MonitorCallOnly { run SipThirdPartyCharging }
else { run SipThirdPartyHttpTrigger run SipThirdPartyCallSetup }
...
}
The configuration for mapping HTTP request to the SIP INVITE message is available under SIP Third Party Call Configuration. The parameters used by the feature are:

Subscription Expiry Feature
The Subscription Expiry Feature ensures that subscriptions end when they expire and Sentinel is acting as the subscription server (endpoint).
The feature monitors the active subscriptions by inspecting the outgoing NOTIFY messages, and sets a timer based on the Subscription-State.expires parameter. If any of the timers associated with the Subscription Expiry feature expire, then leg.endSubscription is used to end the associated subscription. The subscription timers will be cancelled when the subscription has ended (SIP NOTIFY message with subscription-state terminated or leg/session ended).

Behaviour
Matching
The feature first extracts the dialled digit String from the Request URI. If no digits can be found the feature finishes.
If the request URI is a tel: URL with phone-context parameter of geo-local then the feature finishes.
If the number is in international format and is not prefixed by the home country code the feature finishes.
If the number is in international format and is prefixed by the home country code then the prefix will be removed before performing analysis. The feature makes use of the Normalization Component to remove the prefix.
The feature then attempts to match the remaining dialstring first against the FullNumber, and failing that against the Prefix AddressLists.
If a match is found …
-
The Action profile whose name is specified in the matched AddressList Entry is loaded.
-
The actions specified in the Action profile and AddressList entry are performed as described below in Performing Actions.
-
If the match is a prefix match and the action’s
AllowAdditionalPrefixesistrue, matching is repeated against the remainder of the dial string.
If any matched actions have StripMatch set to true then the Request URI, and To: header are updated to reflect that.
Performing Actions
Play Announcement
If the AddressListEntry’s AnnouncementID is > 0 it is added to the SessionState’s EarlyMediaAnnouncementInfoQueue without chargeForAnnouncement or a specified Language.
End the session with a specific response code
If the Action’s EndSessionResponseCode is > 0 it is used to terminate the session after any queued announcements have played or immediately if no announcements are queued.
Change the session plan
If the Action’s PlanId is a non empty string, it is set into the SentinelSelectionKey. This PlanID will be used from the next ExecutionPoint.
Set a specified session state field to a specified value.
If the Action’s SessionStateFieldName is the name of an actual SesionState field …
-
if the Action’s
SessionStateDataSourceis set toSERVICE_CODE_VALUEand the SessionState field is a String field, the matched code is set in that field. -
if the Action’s
SessionStateDataSourceis set toSUFFIXand the SessionState field is a String field, the dial string following the prefix code is set in that field. This may include other service codes that have yet to be processed. -
if the Action’s
SessionStateDataSourceis set toCONSTANTthen-
The Action’s
ValueForConstantDataSourceis attempted to be converted according to the Action’sTypeForConstantDataSource. -
If conversion is successful, the converted value is attempted to be assigned to the SessionState field.
-
Any failures to find the session state field, or convert or assign a value will generate SAS events, trace logs and the feature reports featureFailedToExecute.
Precedence
If multiple matched AddressList Entries request an announcement, then all such announcements will be queued in the order they are matched.
If multiple matched service code Actions specify an EndSessionResponseCode the last one matched applies.
If multiple matched service code Actions set the same SessionState field, the last matched one applies.
If multiple matched service code Actions change the session plan, the last matched one applies.

Configuration
Configuration is split between address lists and profile tables. The address lists contain data that needs to be configured by an operator, such as choosing specific service codes for supplied actions and setting which announcement (if any) is appropriate to that action.
The profile table contains data related to how Sentinel or another feature should be triggered to perform certain service code actions. Any new features which have functionality that could usefully be triggered by service codes should supply their own entries in the profile table.
Vertical Service Code address list configuration
The feature uses an AddressListCollection VerticalServiceCode with lists named Prefix and FullNumber for matching prefix and full number service codes respectively.
They are extensions of the standard Address list entry and both have the same structure with the following additional fields.
| Parameter | Type | Description |
|---|---|---|
… |
… |
… |
Action |
String |
The name of a Vertical Service Code Actions profile to be applied when this service code is found. REM provides a list to select from. |
AnnouncementID |
Integer |
ID of an announcement to be played when this service code is found, set to 0 to disable announcements. REM provides a list to select from. |
Example configuration:

|---|---|---|
*87 |
MMTel_OIR_ID_Restriction_Current_Session_Disable |
0 |
*63 |
MMTel_CDIV_Disable |
20 |
The service code lists apply to all subscribers scoped to Sentinel selection key.
Vertical Service Code Actions profile table configuration
Standard and customised actions are stored in a profile table VerticalServiceCodeActions. The table maps an Action name to the actions to perform. The Action name is the result of looking up the dialstring in the Prefix or FullNumber VerticalServiceCode address lists.

allowAdditionalPrefixes |
Boolean |
If |
endSessionResponseCode |
Integer |
If set to a valid SIP error response code, this action will end the session with that response code. Set to 0 when the action should not end the session. |

The Sentinel Normalizer normalizes International, Unknown, National, or Subscriber NADI format addresses into either: * international address format — starting with CC + MNC * national format — starting with MNC where MNC is specified in the NetworkDialingCode configuration setting. The Sentinel Normalizer may decide to not normalize the address if the address is either: * shorter than the This allows for short codes and specific longer length numbers to avoid normalization. The Normalization is invoked by the call type specific normalization features Voice Call Normalization Feature, SMS Normalization Feature and SIP Normalization Feature. It is also invoked by the XCAP Server to reject requests containing numbers which are not normalizable. Furthermore, MMTelCDIV, MMTelICB and MMTelOCB use the normalization component to normalize numbers in outgoing requests, and when comparing numbers.

Each bucket must have a unique name and can be configured within Sentinel to be of one of the following access types: * External database * Cassandra * SLEE profiles * Sentinel session state * Unlimited. Each promotion must state the name of the bucket to which units shall be charged if the promotion applies. Multiple promotions can charge to the same bucket. If the bucket is configured for ‘external database’ access, the promotion bucket units are held in an external database. == Promotion units Promotion units are generic and can be used to represent any unit type. There is a one-to-one ratio between the value of a promotion unit and the value of the charging unit being deducted by a promotion. For example, if a promotion matches a request for 1024 Octets, then 1024 promotion units will be deducted.

An address list is a searchable collection of addresses. Each address in an address list may also have some associated data. You can use address lists for some of the features bundled with Sentinel, such as: * special prefixes — Prefix and Suffix Analysis Feature does a longest prefix match against a dialled number to see if the dialled address includes one of the prefixes. * short-codes — The Short Code Feature does an exact match against a dialled number to see if the dialled number is a short-code. Each short-code in the address list has the fully qualified address the short-code represents. * global-title addresses — The SS7 Determine Network Operator Feature does a longest prefix match against the destination SCCP address to determine which network operator the new session is for. Each address list has a unique name. The addresses in the address list are stored in SLEE profiles. Sentinel manages a cached digit tree for each address list. The digit tree provides fast exact, longest prefix, and longest suffix matching of addresses. .addresses in an address list called “Prefixes”, mapped into a digit tree image::sentinel-components/features/sip-features/sip-user-features/addresslist.png[] Addresses in an address list are sequences of: 0 … 9, a … f, A … F, #, , . TIP: You provision address lists using the Sentinel Element Manager. See the Sentinel Administration Guide for details. IMPORTANT: Address lists should only be managed with the Sentinel Element Manager or the RESTful HTTP provisioning interface. The SLEE profile tables, how they are named, and many of the fields are internal to Sentinel and the Element Manager. = Profile Tables for Address Lists Address lists are stored using SLEE profiles: * Address list configuration profile — defines configuration properties of the address list (for example, should it be cached). * Address list entry profile — the entries in the address list (and any associated data, if any) [NOTE] ==== An address list is identified by two properties: * *address list name — the name of the address list. For example, the PrefixAndSuffixAnalysis feature uses address lists called: ‘SpecialPrefixList’ and ‘SpecialSuffixList’. * schema name — corresponds to the type of the address list. For example, the PrefixAndSuffixAnalysis feature address lists have the schema name ‘PrefixAndSuffixAnalysis’. Address lists that do not associate any data with an address list entry have the schema name ‘Sentinel’. ==== Sentinel adopts a simple naming convention for mapping an address list schema name to the SLEE profile tables required for address lists that use that schema. * Address list configuration Table Name — <PlatformOperatorName>_<SchemaName>_AddressListConfigurationTable * Address list entry Table Name — <PlatformOperatorName>_<SchemaName>_AddressListEntryTable For example, the PrefixAndSuffixAnalysis feature uses address lists that are stored in these profile tables: * <PlatformOperatorName>_PrefixAndSuffixAnalysis_AddressListConfigurationTable * <PlatformOperatorName>_PrefixAndSuffixAnalysis_AddressListEntryTable Address lists that do not have any data associated with entries in the address list use a schema name of ‘Sentinel’ and are stored in the following SLEE profile tables: * <PlatformOperatorName>_Sentinel_AddressListConfigurationTable * <PlatformOperatorName>_Sentinel_AddressListEntryTable == Address List Configuration Profile Each address list has a configuration profile with these properties: [cols="1,1,3" width="90"] |
|Parameter |Type |Description
|Description |String | |Name |String |The name of this address list |SchemaName |String |The name of the schema of this address list |PlatformOperator |String |… of the Selection key, for this address list to be used |NetworkOperator |String |… of the Selection key, for this address list to be used |SessionType |String |… of the Selection key, for this address list to be used |PlanId |String |… of the Selection key, for this address list to be used |SubscriptionId |String |… of the Selection key, for this address list to be used |DefaultSearchMode|Integer |One of: 0 — exact match, 1 — longest prefix match, 2 — longest suffix match |ShouldCache |Boolean |True, if the Sentinel core should maintain a cached version of the address list in memory |Version |Long |Sentinel core tracks the version for address lists that are cached in memory. If the version changes, then the Sentinel core re-builds the cached version of the address list. The version is incremented by the Sentinel Element Manager, once a set of updates to an address list (either by changing this configuration, or changing list entries) should be applied to any cached versions of the address list in memory.
== Address List Entry Profile Each Address List entry corresponds to a profile with these properties: [cols="1,1,3" width="90"] |
|Parameter |Type |Description
|Description |String | |Address |String |The address string — a sequence of characters matching: 0 … 9, a … f, A … F, #, *, . |listId |String |The list id is a string that identifies the address list this entry belongs to. It has the following form: <selectionkey>:<schemaName>:<listname>
NOTE: Address lists that have additional data will have additional properties for that data. See Using Address Lists in the Extending Sentinel with the SDK guide to understand how a feature uses an address list and how you can associate data with entries in an address list. :leveloffset: -1 :leveloffset!: :ocdoc_current_file: /mnt/ephemeral0/workspace/product/sentinel/sentinel-documentation/release-3.1.0/Auto/sentinel-documentation/target/generated/sentinel-administration-guide/provisioning/index.adoc :here: provisioning/ :idprefix: provisioning :leveloffset: 1 = Provisioning :indexpage: :sortorder: 4 == Using the Sentinel Element Manager You provision Sentinel using the Sentinel Element Manager. The Sentinel Element Manager provides a web interface and machine API for provisioning Sentinel. TIP: The Sentinel Element Manager is an extension of the Rhino Element Manager (REM). See Installing the Sentinel Express Provisioning Module to install the Sentinel provisioning module in REM. For general information on using Rhino Element Manager, see the Rhino Element Manager User Guide. To provision Sentinel, see the procedures to: ==== * Configure the Sentinel REM Extension * Provision Sentinel using the Web Interface * Sentinel Provisioning REST API * Working with CDRs * Configure Auditing of Provisioning Operations * Configure and use the Sentinel XCAP API ==== :leveloffset!: :ocdoc_current_file: /mnt/ephemeral0/workspace/product/sentinel/sentinel-documentation/release-3.1.0/Auto/sentinel-documentation/target/generated/sentinel-administration-guide/provisioning/provisioning-configuration/index.adoc :here: provisioning/provisioning-configuration/ :idprefix: provisioning-configuration :leveloffset: 1 = Provisioning Configuration :indexpage: :sortorder: 1 You set configuration options for the Sentinel provisioning application using a properties file. On startup, the Sentinel provisioning server tries to read this file:

These are the AVP CDR format, and the legacy format. Note that Sentinel can be configured to use a user provided CDR format, or even no CDRs. == AVP CDRs An AVP CDR is an OpenCloud defined CDR that contains AVPs. This type of CDR is consistent with the approaches used in Diameter Ro and Diameter Rf interfaces. An AVP CDR contains AVPs that are standardised (e.g. 3GPP and IETF), or non-standardised (e.g. product specific or project specific). AVP CDRs can almost be considered an "on-disk" form of the content contained in the Rf interface. AVP CDRs are used by default in the Sentinel SIP service. The Sentinel SIP service can be configured to use the legacy format. == Legacy CDRs A legacy CDR is an OpenCloud defined CDR that is used in the Sentinel product set prior to (and during) the introduction of AVP CDRs. The product continues support for this format so that customers who use this format do not need migrate. Legacy CDRs remain in use by the Sentinel SS7 and Sentinel Diameter services. == Topics * AVP CDR Format — describes the formats used for AVP CDRs * Legacy CDR Format — describes the format used for Legacy CDRs :leveloffset!: :ocdoc_current_file: /mnt/ephemeral0/workspace/product/sentinel/sentinel-documentation/release-3.1.0/Auto/sentinel-documentation/target/generated/sentinel-administration-guide/charging-information/cdr-formats/avp-cdr-format.adoc :here: charging-information/cdr-formats/ :idprefix: avp-cdr-format :leveloffset: 1 = AVP CDR Format AVP CDRs have logical content, and an on-disk format. == Logical content Each CDR inside a CDR file has logical content. We use a BNF syntax to describe this logical content. ---- CDR ::= [ Subscription-Id ] [ IMS-Information ] [ User-Equipment-Info ] *[ Multiple-Services-Credit-Control ] [ OC-Call-Type ] [ OC-Service-Type ] [ OC-Charging-Result ] *[ OC-OCS-Session-Id ] [ OC-OCS-Session-Termination-Cause ] [ OC-Sentinel-Error ] *[ OC-Charging-Instance ] [ OC-Event-Id ] [ OC-Call-Id ] [ OC-End-Session-Cause ] [ OC-Session-Start-Time ] [ OC-Session-Established-Time ] [ OC-Session-End-Time ] [ OC-Sentinel-Selection-Key ] *[ OC-Play-Announcement-Id ] *[ AVP ] ---- Logically this means that an individual CDR has optional content. It may have zero or one Subscription-Id AVP, zero or one IMS-Information AVP, and so-on. It may have zero or more OC-Play-Announcement-Id AVPs, and zero or more OC-OCS-Session-Id AVPs, and so-on. A CDR inside the CDR file is not an AVP. It is a protobuf record, and as such may contain additional "root" AVPs. So, for example an application may use the format, but add a LCS-Information AVP, or custom AVP. You could consider each CDR to be roughly equivalent to the Service-Information AVP, yet more flexible/extensible regarding its content. This is because the Service-Information AVP is essentially closed for extension by non-3GPP groups. To view the population of AVPs in use, refer to Charging Content AVPs == On disk format AVP CDRs are written using Google protocol buffers (protobuf). An AVP CDR file has a protobuf schema.

This format has several benefits over the once-per-session CDRs written by the session-based CDR features: . Improved failure characteristics. Interim CDRs are recording more frequently during a session, so any system failures will result in less records being lost. . Interop with offline charging systems. This format is designed to reflect the message content requirements for interaction with offline charging systems via the Rf interface. . More accurate. This format records changes in specific AVPs (e.g. SIP SDP AVPs) during the lifecycle of a session allowing changes in media state to be more accurately tracked. == Interim CDR content Interim CDRs are written as a collection of AVPs conforming to the definitions listed in Sentinel AVP definitions. In addition to the standard AVPs, Interim CDRs contain additional AVPs to facilitate interpretation and correlation of their content. These additions are summarized in the following table: [cols="2,3,2" options="header"] |
| AVP | Description | Specification | Accounting-Record-Type | Lifecycle enum indicating when the record was written. See below table. | RFC 6733 | Accounting-Record-Number | Unique-per-session number starting at 0 indicating how many records have been written for this session. | RFC 6733 | OC-Interim-CDR-Reason | Contains the leg the Interim CDR relates to, and the reason it was written. | Sentinel AVP definitions
The [cols="2,2" options="header"] |
| Accounting-Record-Type | When written… | START_RECORD | When a session is established (answered). | INTERIM_RECORD | Mid-session, either in response to SDP changes or based on timer events (both configurable). | STOP_RECORD | When a session finishes. | EVENT_RECORD | When the last Interim CDR written is also the first one written, e.g. for recording of one-off SMS events.
== Interim CDR Correlation If the IMS Charging Identifier (ICID) is present during network interactions it will be included in all Interim CDRs produced for a session. When Running List CDRs, ICIDs present in a CDR file can be listed with == Related features //// * README README README * Maintenance note: This entire section is overridden downstream in sentinel-volte-documentation. If you make updates here, also make them downstream! //// For configuring when Interim CDRs are written, refer to the Sip Interim Cdr feature documentation. Other features can inform the Sip Interim Cdr feature of important session state changes by writing values to the control fields defined by the The features which affect the behaviour of the Sip Interim Cdr features are: [cols="2,3" options="header"] |
| Feature | Behaviour | Determine Chargeable Leg Feature | Determines which leg to charge then records it to the LegForCdrs session state field. | SDP Monitor Feature | Detects when SDPs have changed and sets the WriteCdrOnSDPChange session state field. This instructs the Interim CDR feature to (if configured) write an interim CDR when SDPs have changed.
== Controlling when Interim CDRs are written The Interim CDR feature writes CDRs at specific points during a session. There are several mechanisms to control when interim CDRs are written including feature configuration and session state control fields, as described in the feature documentation. == Example call flow Below is an annotated call flow indicating where Interim CDRs are written during a typical SIP Mobile Originating session. image::generated/mo-with-ocs-interim-cdrs.png[] == Extending CDR content //// * README README README * Maintenance note: This entire section is overridden downstream in sentinel-volte-documentation.

Individual CDR records will vary in size based on dynamic content such as hostnames, Sentinel selection key names, SDP content, and other similarly variable character data. As such, it is not possible to provide exact sizing for a given system without examining the CDR logs written while under a test load, but some approximations can be made. A basic CDR record containing the information normally written by Sentinel will be on the order of 2000-3000 bytes. With this in mind, the following sections provide rough estimates regarding how much storage would be required for specific scenarios. If Sentinel is configured to write Session CDRs (i.e. not writing Interim CDRs), then each session will write a single CDR on the order of 2000-3000 bytes. == Interim CDR Sizing This section documents the storage requirements for the AVP CDRs written by the CDR RA when Sentinel is configured to output Interim CDRs. === B2BUA CDR Sizing This scenario involves writing CDRs for a single leg of a two party call. Assuming a Start and End CDR are always written for the call, and assuming an average CDR size of 2500 bytes, each call will require a minimum of 5000 bytes. In addition, the Interim CDR feature can be configured to write CDRs periodically as a call progresses, or in response to SDP changes. Each of these events will produce additional records. Taking these additional timer driven and SDP driven records into account, a rough approximation of the CDR storage requirements can be made with a formula such as:
It isn’t possible to use average call length when calculating storage requirements for timer driven CDRs as the number of timer driven CDRs written per call is sensitive to actual rather than average call length. With the guideline above, we can perform approximations based on an example scenario: * No SDP changes outside of initial call setup. * 95% of calls last under the default Interim CDR timer threshold (5 minutes by default). * 5% of calls last for 59 minutes and trigger numerous timer driven Interim CDRs during that period. With a 5 minute interim CDR timer, this will mean 11 timer driven interim CDRs. * The overall system is running at 100 session per second. Using the above, we can assume that the average number of interim timer CDRs per call is

Refer to CDR Resource Adaptor section of this guide for more information about Sentinel and the CDR RA. == List CDRs The Sentinel SDK contains a List CDRs tool, which can be used to print Sentinel’s binary CDRs files to a human readable format. The CDR files contain binary encoded Diameter AVPs files in addition to a header and footer. The List CDRs tool decodes the binary CDR file and all the Diameter AVPs which is contains, printing them to the console. It also supports printing the older 'legacy' CDR format which is not based on AVPs, as used by Sentinel version 2.4.x and earlier.
