Sentinel VoLTE 2.9.0 Changelog

Ensure SCC Terminating Pre Answer Session Transfer feature uses the correct direction 'receiver' in generated INFO request. (VOLTE-9822)

Correct null pointer error when IDP of reoriginating call has no callingParty field. (VOLTE-9572)

Add an index to the participant id field of conference view profiles to speed up profile handling and reduce concurrency issues. (VOLTE-9559)

Copy Session-Expires and Min-SE headers across messages during pre-answer access transfer. (VOLTE-9191)

Changed the SIS composition on-timeout behaviour when invoking the Registrar from ignore-and-continue to terminate-processing. The SIS will no longer forward the request (based on the Request-URI) and instead send a 504 response to the received REGISTER request. Also changed the status code of the response sent on SIS trigger failure from 503 to 500. (VOLTE-9376)

Update the IMSSF dependency to 2.6.2.9

Update the SIS dependency to 2.6.2.15

Improve MediaDescription comparison in VolteSdpUtil so that a media description rtpmap attribute which includes an explicit channel declaration (/1) is considered equivalent to the same rtpmap attribute that implies a single channel is in use (without /1). (VOLTE-8810)

Fix an issue in the MMTelCONF feature that meant BYEs received from the MRF on a participant leg did not generate NOTIFY messages. Due to a logic bug MRF BYEs were not associated with an active connection and as a result NOTIFY messages were not generated to update other participants view of the conference state. (VOLTE-8735)

Update SentinelVolteAndRegistrarOriginatingTrigger and SentinelSipServiceAndImssfOrigTrigger to explicitly identify the P-Served-User "orig-cdiv" parameter. If present invoke originating processing for the served user. The lack of explicit handling for the P-Served-User "orig-cdiv" parameter resulted in the incorrect invocation of terminating processing. (VOLTE-8722)

Fix logic issue in MMTelCW that resulted in the feature raising FeatureFailedToExecute when triggered on a TimerEvent other than the call waiting timer. (VOLTE-8630)

Update the Sentinel SS7 dependency to 2.9.0.4 `

Update SentinelSipServiceAndImssfTermComposition to avoid IMSSF sending the INVITE with original Request-URI. (VOLTE-8200)

Fix a regression in the FetchMSRN feature, correctly calculate the encoding type of the HLR’s SCCP Address when using the subscriber’s MSISDN to address the HLR. (VOLTE-8198)

Populate access network information using the HLR response in the DetermineRoamingFromHLRFeature. (VOLTE-7614)

Remove a restriction for Re-INVITE based conference calls. (VOLTE-7877) The originating attempt from the moderator towards the conference factory is now able to traverse originating Application Servers. This means that once a conference is established, the conference moderator may access transfer, and the conference continue. Additionally the iFC is simplified as conferencing may be invoked using regular Terminating AS iFC. Each conference factory identity must still remain as a Public Service Identity in order to trigger the terminating MMTel AS for the call towards the conference factory (terminating unregistered). When the originating attempt towards the conference factory occurs - there will now be charging (e.g. Ro / Rf / CDRs) for that session as for any other originating attempt. The IM-SSF proxies Initial Requests without contacting the Service Control Point if the Request-URI (i.e. Conference Factory PSI) is not a phone number. Note: Moderator control of the conference is not transferred to the CS domain as this requires the so called "MSC Server Enhanced for IMS Centralised Services" that is mutually exclusive with the MSC Server invoking CAP triggers for non-roaming subscribers. Additionally the SCC-AS requires several additional capabilities to support the "MSC Server Enhanced for IMS Centralised Services".

Fix bug to allow alerting and pre-alerting access transfers to work across multiple nodes. (VOLTE-7688)

Add new feature VolteDetermineRegistrationSessionType that has ESRVCC capabilities. (IPSMGW-981)

Add MMTel-SService-Type AVP in situations where only ODB runs during MMTelICB, and MMTelOCB features. (VOLTE-6624)

Change how the CSRN is determined when TADS routes to CS. There is now a config flag called UseHLRBasedCSRN in the VolteServiceConfigProfileTable profile table. When true the MSRN (GSM) or TLDN (CDMA) is used, when false the CMSISDN is used. Both options have still have a configurable prefix. (VOLTE-6621)

Add SAS logging to SetOcsAnnouncementId feature. (VOLTE-6021)

Add SAS logging to IMSIDLookup feature. (VOLTE-6020)

Update DetermineRoamingFromHLR feature to perform an ATI if a SIP response indicates the terminating user is in a CS network. A new feature script MMTelTerm_HLR_SipAccess_PartyResponse has been created to run DetermineRoamingFromHLR on initial SIP responses. On installation, if GSM is enabled this feature script will be configured to run at the SipAccess_PartyResponse:sipcall:mmtel-term: execution point. (VOLTE-6429)

Update SCCCamelToIMSReOriginationSIPFeature to set OC-VLR-Number value to be in a parsable format. (VOLTE-6155)

If the MMTelCDIV NoReplyTimer is set outside the allowed range (5-180), set it to the minimum or maximum allowed value. (VOLTE-6205)

Add missing SAS event for SendRoutingInfo-v3Request in FetchMSRN feature. (VOLTE-6328)

Reject XCAP provisioning requests that contain non-normalizable numbers, and normalize CDIV targets and ICB/OCB conditions. The XCAP server pulls in the configuration from Rhino, with a configurable caching duration. (VOLTE-6211 - VOLTE-6216)

Make MMTel features no-op if subscriber data indicates feature is not authorized. The default behaviour when operator data is not present is configurable (true/false). When provisioning a subscriber through REM or the REST server, all authorized flags are now mandatory. To make this new functionality work for MMTelCONF in existing installations, add the relevant SubscriberDataLookup feature to the MMTelConf_SipAcess_SubscriberCheck feature script. (VOLTE-6232, VOLTE-6254 - VOLTE-6257, VOLTE-6312)

Make MMTelCDIV and MMTelICB/MMTelOCB support raw numbers. If the subscriber provisions a raw number (i.e. not a sip or tel URI), interpret this as a tel URI. (VOLTE-6288)

Add a list of non-provisionable retarget URIs to the MMTelCDIV feature and XCAP provisioning service. If a subscriber tries to provision a retargeting rule with a target on the non-provisionable retargeting list, the request is denied. Before MMTelCDIV retargets a request, it checks if the new target is on the non-provisionable retargeting list. If so, the retargeting rule is ignored. (VOLTE-6217 - VOLTE-6221)

Update default Post_SipAccess_SubscriberCheck execution scripts to run RecordTimestamps feature. (VOLTE-6412)

Fix a bug in the DetermineRoamingFromHLR feature. If the feature was unable to send a MAP AnytimeInterrogation Request it would pause execution for five seconds. (VOLTE-6317)

Update DetermineRoamingFromHLRFeature to extract phone number from the SIP URI regardless of whether user=phone parameter is present. (VOLTE-6317)

Update VolteInterimCdr feature to maintain extension AVPs added to ACRs by the BaseInterimCdr feature. (VOLTE-6577)

First release in the 2.8.0.x series.

Add support for session replication and failover for MMTel and SCC sessions. This support is optional, the product can be used without the capabililty. Architecture documentation for this capability is described in Session Replication. DNS configuration to support session replication and failover is described in Non-sharded DNS configuration and SRV configuration for fail-over of sticky sessions.

In order to support session replication and failover, the External Session Tracking features have been replaced and a new Facility has been added to Rhino, the Session Ownership Facility. The External Session Tracking features have been replaced with a single feature called External Session Tracking.

A new feature, named Access Leg Tracking is responsible for SR-VCC specific tracking logic within the SCC-AS.

Features gain support for session replication in a near transparent manner through the new Rhino 2.6.1 Key/Value Store. Software changes to enable session replication have been performed underneath existing APIs. For standard or "out of the box" features, this meant migrating API calls from SipSession.get/setAttribute to Sentinel Session state CMP fields. SipSession.get/setAttribute API still exist and function as they did previously, i.e. do not replicate. Custom features should use Session State, i.e. CMP APIs for their state variables.

Additional semantics and annotations for CMP fields have been added to Rhino. For details please refer to CMP Field Enhancements within Rhino 2.6.1 documentation.

Support for replicated SIP Dialogs has been added to the SIP-SIS. For details please refer to SIP Session Replication

Add support for CDMA traffic in O-SDS and T-SDS (Reorigination) scenarios and in T-ADS delivery to CS. See CDMA and SIP support for SCC for a description of the architecture, CDMAFetchTLDN for a description of the T-ADS functionality, and CDMA Reorigination Service for a description of the reorigination service.

Support for deploying SIS without CGIN for GSM has been added to the SIS, see xref:<sis-documentation/2.6.1>whats-new-in-this-version/what-s-new-in-this-version#split-sis-packages[Split SIS packages]

During subscription processing check the p-asserted-identity, From and Contact headers (in that order) for possible identity and use the first that corresponds to a member of the conference. (VOLTE-5250, VOLTE-5484, VOLTE-5485)

Miscellaneous improvements to build infrastructure to enable Standalone Packages.

Enable use of Rhino’s arbitrary CMP fields in all Sentinel features (VOLTE-3028)

Removed no-args constructor from com.opencloud.sentinel.util.TableExistsVerifierImpl (STLCORE-70). New implementation requires a ProfileFacility as an argument.

The binder no longer generates or installs empty bindings descriptors for library and profile modules. (SDKTOOLS-136)

Fixed a bug where unbind would fail to unbind a module from a service when the module was bound into that service due to a bind-with-deps operation on a downstream module. (SDKTOOLS-135)

Fixed bug which caused binding to fail on some file systems such as eCryptfs due to long file names, and improve failure handling in the binder. (SDKTOOLS-134)

Fixed bug where mapper classes with multiple mappers were not getting renamed properly during module creation from module packs (SDKTOOLS-130)

Fixed provider injection warning from PromotionsCommitUsedUnits feature (STLCORE-54).

Fixed incorrect JNDI context being used in subsequent pojo feature execution when the initial execution cycle was initiated by an SBB feature event handler (STLCORE-46).

Improved handling of how the top-level module is renamed when using the 'create-module' command (SDKTOOLS-92)

Changed behaviour of sdkadm -f and -e arguments. These will now exit sdkadm after executing the specified commands unless the new -i (force interactive) argument is specified.

Added -q option to sdkadm which will suppress some command processing logging.

Renamed default resolvers to online-resolvers.xml. Added offline-resolvers.xml.

Split local resolver configuration out into local-resolvers.xml.

Added support for property injection during <default-module-build> macrodef execution. Any properties written to ${generated}/build.properties prior to <default-module-build> will be available during annotations processing.

Renamed 'clean' target to 'clean-module', and renamed all non-branch publish-* targets to 'publish-*-module'. All targets named *-module now operate only on a module, whereas all targets named *-branch will operate recursively. e.g. publish-local-module will publish the current module, whereas publish-local-branch will publish the current module and all nested children. (BLDSUPP-19)

Certain targets (clean, publish-*) are now 'dynamic' and will behave differently based on where they are executed. e.g. executing 'publish-local' in a module which has nested modules will publish all nested modules (i.e. a publish-local-branch), whereas running 'publish-local' in a module with no children will invoke 'publish-local-module'. The non-dynamic behaviour can still be explicitly invoked via the *-module or *-branch target variants (BLDSUPP-19).

IDE setup targets (idea-setup, eclipse-setup, idea-clean, eclipse-clean) are now only available in the root of an SDK (STLPACK-182).

Relevant targets for each module build are now determined automatically based on module type and content. Old build files should be modified to remove imports of 'build/default-branch-targets.xml' and 'build/default-targets.xml' and instead import the unified 'build/targets.xml'. The old import statements will continue to work to enable backwards compatibility with 2.3.1 SDKs, but they will produce a runtime warning on each build.

All temporary build infrastructure artifacts are now written to the build/target directory. Repositories created by go-offline will be put into the repositories directory. Module build output remains in MODULE/target/. (BLDSUPP-34, STLPACK-35)

Added example Python script for REST API interactions to build/bin/

Updated the SentinelRAAToRoOcsRAA and SentinelRAAToDccaOcsRAA mappers to use application specific message factories so that RAAs sent by Sentinel will include the right Diameter Application-Id. (STLCORE-38)

Update the SIS dependency to 2.5.2.21

Miscellaneous bugfixes and improvements

Add deploy-module, bind-module and configure-module commands to sdkadm

Improve user control over the configurer’s and deployer’s dependency traversal order (SDKTOOLS-40). Module authors can now specify e:configureorder to control the traversal order of a module and its dependencies. Much like the existing e:deployorder, it defines the modules as a comma separated list of module names. For both e:configureorder and e:deployorder, the module itself can now be included at any point in the given order. I.e. the module itself can be configured/deployed either before or after its dependencies.

Adjust some memory properties for the default Rhino SDK. Set the max new size to 512MB, and set the heap minimum and maximum size to 2048MB

Add support for module property propagation between modules that publish properties

AVPs used on the Rf interface are described in the Charging Information section of the Administration guide.

The Interim CDR Feature can now be configured use the Rf Control Resource Adaptor, as well as AVP CDRs.

Out-of-the-box Diameter AVPs for Ro and CDRs are now based on 3GPP Rel 12, rather than 3GPP Rel 8.13.0 as in earlier releases. Rf AVPs are Rel 12.

The Diameter Ro Resource Adaptor has been updated to the 3.1.0.x release series, enabling AVP version downgrade/upgrade between Rel 12 and older versions. The Ro Resource Adaptor can now be configured with a SLEE API version that is different to the "wire" protocol version for the OCS. Downgrading from Rel 12 is supported as far back as Rel 8.13.0. For further information refer to Diameter Resource Adaptors Changelog.
