16、 Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee IMS Network Testing (INT). The present document is part 3 of a multi-part deliverable covering Conference (CONF), as identified below: Part 1: “Protocol Implementation Conformance Statement (PICS)“; Part 2: “Te

ETSI ETSI TS 186 010-3 V3.1.1 (2012-01)51 Scope The present document specifies the Abstract Test Suite (ATS) and partial Pro
18、tocol Implementation eXtra Information for Testing (PIXIT) proforma based on the Test Suite Structure and Test Purposes defined in TS 186 010-2 2. The test notation used in the ATS is TTCN-3 (see ES 201 873-1 7). The following test specification- and design considerations can be found in the body of
19、 the present document: the overall test suite structure; the testing architecture; the test methods and port definitions; the test configurations; the design principles, assumptions, and used interfaces to the TTCN3 tester (System Simulator); TTCN styles and conventions; the partial PIXIT proforma;
20、the modules containing the TTCN-3 ATS. Annex A provides the Partial Implementation Extra Information for Testing (PIXIT) Proforma of the ATS. Annex B provides the Testing and Test Control Notation (TTCN-3) part of the ATS. 2 References References are either specific (identified by date of publicatio
21、n and/or edition number or version number) or non-specific. For specific references, only the cited version applies. For non-specific references, the latest version of the reference document (including any amendments) applies. Referenced documents which are not found to be publicly available in the

31、ntifies the path of groups/subgroups); c) is a running 3-digit decimal number, starting in each subgroup path with “001“. EXAMPLE: TC_CONF_N01_001: i) the identifier has Group index “CONF_N01“, i.e. it is in the subgroup having complete path: SupplementaryServices_CONF/ConferenceFocus/CreateConf; ii
32、) the identifier is the first test case of this group/subgroup. NOTE: This naming scheme provides a 1-1 correspondence of TP identifiers as defined in TS 186 010-2 2 and test case names. The TP identifier of TC_CONF_N01_001 is TP CONF_N01_001. 5.3 ATS specification framework 5.3.1 ATS Library For th
33、is ATS the TTCN-3 library modules are basically organized as: 1) AtsCommon modules. 2) LibIms modules. 3) LibSip modules (RFC 3261 4). 4) LibCommon modules (taken from an improved version of TS 102 351 8). NOTE: Due to the common LibSip and LibIms library approach with some other parallel running pr
34、ojects there is necessary to create tag version of all library modules. Table 2 shows the organization of the ATS as library of modules.

43、ght clause related to the text of the present document, grants that users of the present document may freely reproduce the PIXIT proforma in this annex so that it can be used for its intended purposes and may further publish the completed PIXIT proforma. A.1 Introduction This partial PIXIT proforma
44、contained in the present document is provided for completion, when the related Abstract Test Suite is to be used against the Implementation Under Test (IUT). The completed partial PIXIT will normally be used in conjunction with the completed PICS, as it adds precision to the information provided by
45、the PICS. A.2 PIXIT items According to the type of ATS defined in the present document, the PIXIT are divided in PIXIT items for UE, AS and general PIXIT items that apply for all types of IUT. Each PIXIT item corresponds to a Module Parameter of the ATS. NOTE: The PIXIT definitions are part of a SIP
46、 TTCN-3 library that contains additional PIXIT definitions that are not used in this ATS and are therefore not presented in the following tables.
