Below are common configuration properties that all Diameter resource adaptors use, followed by properties specific to:

Configuration properties for transport security (TLS) and more information about configuring TLS can be found on Configuring Diameter Transport Security.

The Diameter resource adaptors support active reconfiguration. This means that (most) configuration properties can be updated without deactivating and re-activating the resource adaptor entity. If a property cannot be updated at runtime, then an alarm is raised indicating that the entity must be deactivated and re-activated. The tables below indicate which properties allow active reconfiguration.

For profile-based configuration, some of the attributes can be changed while active. See Configuration Profiles for details. The profile is polled for changes according to the value of ConfigurationProfilePollTime. (This is disabled by default.)

Diameter Base configuration properties

Diameter Base also uses this configuration property:

Property What it specifies Values Default Active reconfig?

VendorSpecificApplicationId

value to put into the Vendor-Specific-Application-Id AVP in CER/CEA and CUR/CUA messages

grouped AVP containing a Vendor-Id field and a Auth-Application-Id field — must contain both values in the format Vendor-Id:Auth-Application-Id

Yes

Active reconfiguration of this property automatically triggers sending CUR message to all active peers supporting RFC6737.

Diameter Accounting/Rf configuration properties

Diameter Base Accounting and Diameter Rf also use these configuration properties:

Property What it specifies Active reconfig?

StatefulSessionTimeout

value for Ts as defined by section 8.2 of RFC 6733 — the timeout value for stateful accounting sessions

Yes

AcctInterimInterval

value to include (if specified) in an Acct-Interim-Interval AVP for Accounting-Answer, when starting a session

Diameter 3GPP configuration properties

Diameter resource adaptors that implement a 3GPP reference point (Ro, Rf, Gx, and Sh) also use this configuration property.

Property What it specifies Values Active reconfig?

3GPPVersion

3GPP version of protocol supported by the resource adaptor

two forms allowed:

  • in the form of Vxyz, where xyz is three-character version number used in names of 3GPP specifications; for example, V710 for V7.1.0 or Va00 for V10.0.0. The value is case-sensitive: the V must be uppercase and other letters lowercase.

  • in the decimal form x.y.z; for example, 7.1.0 for V7.1.0 or 10.0.0 for V10.0.0. There is no V letter, only the decimal version number.

Note Prior to Diameter 2.6.0 this value was optional and a "default" version would be used. From 2.6.0 onwards a value must be supplied or the resource adaptor will not activate. See additional notes below.

No

3GPP version

Your SBB must use the provider factory method and the types sub-package that matches the value you specify, unless the Slee3GPPVersion is set. For example, for Ro V10.0.0 (3GPPVersion=Va00) or (3GPPVersion=10.0.0), you would use the provider method

RoProviderFactory.getRoProviderVa00()

and import your Diameter types from the package

org.jainslee.resources.diameter.ro.types.va00
Note

Diameter SLEE 3GPP configuration properties

Diameter Ro and Rf resource adaptors use this configuration property to specify a different 3GPP version for internal use (by the SLEE) than that used externally (on the network). The Slee3GPPversion specifies the API used by any SLEE application built using the Diameter Ro or Rf resource adaptors. If configured differently from the 3GPPVersion then all diameter messages will be converted as follows:

  • Incoming messages received from the network will be converted from the received version (3GPPVersion) to the SLEE version (Slee3GPPVersion) before being processed by a SLEE application

  • Outgoing messages will be converted from the internal version (Slee3GPPVersion) to the external version (3GPPVersion) before being sent on the network

  • Any AVPs not valid or without equivalent AVPs in either target version will be lost.

Property What it specifies Values Active reconfig?

Slee3GPPVersion

3GPP version of protocol supported by the SLEE(application)

If specified, two forms allowed:

  • in the form of Vxyz, where xyz is three-character version number used in names of 3GPP specifications; for example, Vcb0 for V12.11.0. The value is case-sensitive: the V must be uppercase and other letters lowercase.

  • in the decimal form x.y.z; for example, 12.11.0 for V12.11.0. There is no V letter, only the decimal version number.

Otherwise, Slee3GPPVersion is the 3GPPVersion

No

SLEE 3GPP version

Your SBB must use the provider factory method and the types sub-package that matches the Slee3GPPVersion you specify, if notspecified the 3GPPVersion provider factory should be used. For example, for Ro V12.11.0 (Slee3GPPVersion=Vcb0) or (Slee3GPPVersion=12.11.0), you would use the provider method

RoProviderFactory.getRoProviderVcb0()

and import your Diameter types from the package

org.jainslee.resources.diameter.ro.types.vcb0

Diameter CCA/Ro/Gx configuration properties

Diameter CCA, Diameter Ro, and Diameter Gx also use these configuration properties.

Property What it specifies Values Default Active reconfig?

ServiceContextId

value to put into the Service-Context-ID AVP for all messages

string value specified as "service-context" "@" "domain" (see RFC 4006 section 8.42)

diametercca
@opencloud.com

Yes

ExtensionMessages

if true, support both Diameter base and Diameter application specific sessions (CCA, Ro, Gx); otherwise allow only processing of messages that are explicitly used within Diameter application (as specified by corresponding RFC and 3GPP specifications for CCA, Ro, Gx)

true, false

false

Yes

ReplicateActivities

enable credit control session state replication, so that dialog activities can continue on other cluster nodes after a node failure; if true, replication is enabled; requires a clustered production Rhino installation

true, false

false

No

ReplicateByDefault

start replicating new Diameter sessions on creation:

  • true — Diameter sessions start replicating as soon as they are created;

  • false — replication must be enabled per-session by calling startReplicating() on the session activity.

Note Requires a clustered production Rhino installation. Only applicable when ReplicateActivities is set to true and Rhino is configured to use Key/Value replication.

true, false

false

Yes

TxTimeout

timeout for waiting for responses before firing a RequestTxTimeout event (RFC4006 Tx Timer); session state after timeout depends on Credit-Control-Failure-Handling AVP or Direct-Debiting-Failure-Handling AVP (RFC4006 section 5.7 and section 6.5 respectively)

number of milliseconds; 100 or greater

10000

Yes

ValidityTimeBasedTccTimeout

Controls Tcc session supervision timer driven behaviour (RFC 4006 section 13 and section 7).
Supported values:

  • -1 = Tcc timer disabled

  • 0 = Tcc timer initialized to 2 x Validity-Time AVP seconds

  • >0 = provides a default Validity-Time AVP value. Whenever answer does not contain a Validity-Time AVP, that AVP is added by RA with value equal to defined ValidityTimeBasedTccTimeout. Processing continues exactly as in case of 0.

integer value -1, 0, >0

0

No

CCSessionFailover

provides a default value for CC-Session-Failover AVP for credit control server sessions created by RA (RFC4006 section 8.4); if configuration value is specified, it is automatically set in outgoing answers that do not already contain this AVP

optional string parameter; if provided, must be one of: FAILOVER_NOT_SUPPORTED, FAILOVER_SUPPORTED

Yes

CreditControlFailureHandling

provides a default value for Credit-Control-Failure-Handling AVP for credit control server sessions created by RA (RFC4006 section 8.14); if configuration value is specified, it is automatically set in outgoing answers that do not already contain this AVP

optional string parameter; if provided, must be one of: TERMINATE, CONTINUE, RETRY_AND_TERMINATE

Yes

DirectDebitingFailureHandling

provides a default value for Direct-Debiting-Failure-Handling AVP for credit control server sessions created by RA (RFC4006 section 8.15); if configuration value is specified, it is automatically set in outgoing answers that do not already contain this AVP

optional string parameter; if provided, must be one of: TERMINATE_OR_BUFFER, CONTINUE

Yes

InitialTerminateDuplicateHandling

switch the responsibility for handling of duplicated INITIAL and TERMINATION session credit-control requests (CCR with CC-Request-Type AVP equal to INITIAL_REQUEST or TERMINATION_REQUEST) between RA or service.
Supported values:

  • NO — RA upon receiving duplicated CCR with CC-Request-Type AVP equal to INITIAL_REQUEST or TERMINATION_REQUEST automatically generates an error response and terminates the session

  • SERVICE — RA does not handle duplicated session credit-control CCRs automatically, service is responsible for detecting and appropriately handling duplicates, service is also allowed to send duplicated CCRs.

Note Duplicated TERMINATION session credit-control requests are handled up to LingerOnTerminate milliseconds after CC session reaching Terminated state. For description of LingerOnTerminate see below.

string parameter; must be one of: NO, SERVICE

NO

Yes

LingerOnTerminate

delay ending diameter activity by LingerOnTerminate milliseconds after CC session reaching Terminated state; must be disabled (set to 0), if InitialTerminateDuplicateHandling is set to value NO
