This feature constructs IMS-Information AVPs that record information about the call, for use in CDRs and Diameter Ro Credit-Control-Requests.

The feature name is DiameterServiceInfo, as it is based on 3GPP TS 32.299 v12.11.0 (vcb0).

TerminatingInterOperatorIdentifier

String

Used for the Terminating-IOI AVP in the Inter-Operator-Identifier AVP. Set by the StoreHeaderInfo feature.

IMEI

String

Used as the User-Equipment-Info-Value AVP in the User-Equipment-Info Grouped AVP. Set by the StoreHeaderInfo feature.

UserSessionId

String

The session’s Call-ID, used for the User-Session-Id AVP. Set by the StoreHeaderInfo feature.

IMSChargingId

String

The icid-value parameter of the SIP "P-Charging-Vector" header, used as the IMS-Charging-Identifier AVP. Set by the StoreHeaderInfo feature.

CallType

Enum

Used to set the Subscriber-Role AVP. Set by the DetermineCallType feature.

AccessNetworkInfo

String

Used for the Access-Network-Information AVP. Set by the StoreHeaderInfo feature.

DiscoveredAccessNetworkInformation

String

Used for the Access-Network-Information AVP if the AccessNetworkInfo isn’t set. Set by application level features.

DiameterCauseCode

int

Used for the Cause-Code AVP, indicating how the session ended. Set by the DetermineCauseCode feature.

ChargingIdentifier

String

Used for the 3GPP-Charging-Id or Access-Network-Charging-Identifier-Value AVPs. Set by the StoreHeaderInfo feature.

Outputs

Name Type Description

ImsInformation

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

The IMS-Information AVP that will be written to a CDR, or sent in a Credit-Control-Request. This AVP is defined in 3GPP TS 32.299 v12.11.0 ยง7.2.77.

CallId

String

The SIP Call-ID of the current session.

EventId

String

The subscribed event ID, if present.

Behaviour

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.
