IPRs essential or potentially essential to the present document may have been declared to ETSI. The information
pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found
in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in
respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web
server (http://webapp.etsi.org/IPR/home.asp).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee
can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web
server) which are, or may be, or may become, essential to the present document.
Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Telecommunications and Internet
converged Services and Protocols for Advanced Networking (TISPAN).
The present document is part 2 of a multi-part deliverable covering the IMS NNI Interworking Test Specifications, as
identified below:
Part 1: "Test Purposes for IMS NNI Interworking";
Part 2: "Test Descriptions for IMS NNI Interworking".

1 Scope
The present document specifies interoperability Test Descriptions (TDs) for IMS 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 Release 7 [1]. TDs have been specified on the basis of the Test Purposes (TPs) and Test
Suite Structure (TSS) presented in TS 124 229 [1]. TP fragments presented in the present document as part of TDs are
defined using the TPLan notation of ES 202 553 [5]. TDs have been written based on the test specification framework
described in TS 102 351 [3] and the interoperability testing methodology defined in TS 102 237-1 [4],
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 (TS 124 410 [10]), CDIV (TS 124 404 [11]), ACR-CB (TS 124 411 [12]) and OIP/OIR (TS 124 407 [13]) have
been used.
The scope of these test descriptions is not to cover all requirements specified in TS 124 229 [1]. 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. The latter requirements have been dealt with from a UE and conformance perspective
in TS 134 229 [6].

4 IMS NNI Interoperability Test Specification
4.1 Introduction
The IMS NNI Interoperability Test Descriptions (TDs) defined in the following clauses are derived from the Test
Purposes (TPs) specified in TS 186 011-1 [2]. The TDs cover both basic call procedures such as call establishment and
call release and a selection of the most common supplementary services.
