IMS Network Testing (INT); IMS NNI Interoperability Test Specifications; Part 2: Test description for IMS NNI Interoperability
|Publication Date:||1 May 2012|
The present document specifies interoperability Test Descriptions (TDs) for Inter-IMS Network to Network Interface (II-NNI) interoperability testing for the IP Multimedia Call Control Protocol based on Stage 3 Session Initiation Protocol (SIP) and Session Description Protocol (SDP) standard, TS 124 229 . Interconnection aspects between two different IM CN subsystems for end to end service interoperability are based on standard TS 129 165 . TDs have been specified on the basis of the Test Purposes (TPs) and Test Suite Structure (TSS) presented in TS 186 011-1 . TP fragments presented in the present document as part of TDs are defined using the TPLan notation of ES 202 553 . TDs have been written based on the test specification framework described in TS 102 351  and the interoperability testing methodology defined in TS 102 237-1 , i.e. interoperability testing with a conformance relation.
For the assessment of IMS core network requirements related to the ISC interface parts of the supplementary services HOLD (see TS 124 410 ), CDIV (see TS 124 404 ), ACR-CB (see TS 124 411 ), and OIP/OIR (see TS 124 407 ) have been used.
The scope of these test descriptions is not to cover all requirements specified in TS 124 229 . TDs have been only specified for requirements that are observable at the interface between two IMS core network implementations, i.e. IMS NNI.
NOTE: Requirements pertaining to a UE or an AS implementation or IMS core network requirements that can only be observed at the interface between UE and IMS CN are explicitly not within the scope of the present document.
