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

24、: “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, n

25、o 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

26、 Specification (TS) has been produced by ETSI Project Telecommunications and Internet Protocol Harmonization Over Networks (TIPHON). The present document is part 2 of a multi-part deliverable covering Interoperability test methods and approaches, as identified below: Part 1: “Generic approach to int

27、eroperability testing“; Part 2: “H.323-SIP interoperability test scenarios to support multimedia communications in NGN environments“. Introduction The objective of the project team that produced the present document was to develop TIPHON Release 4 - H.323 - SIP Interoperability Test Scenarios“. The

28、other objective was to provide information, based on this particular exercise, for further development/enhancement/correction of the meta-protocol and the relevant profiles of the TIPHON technical specifications. The initial analysis showed that the TIPHON documentation (H.323 and SIP profiles) for

29、Release 4 was not finalized at the time of writting the present document. So the present document concentrates on the TIPHON Release 3 documentation. To prepare the present document, the project team used the following publications as input: TR 101 308 14, TS 101 314 5, TS 101 315 6, TS 101 882 8, T

30、S 101 883 11, TS 101 884 12, TS 101 878 7, ITU-T Recommendation H.323 1, RFC 2327 10 and RFC 3261 9 standards. ETSI ETSI TS 102 237-2 V4.1.1 (2003-12) 6 1 Scope The present document describes an H.323-SIP Interoperability Test Suite focusing on test cases for functionality that include protocol inte

31、rworking. It is based on the documents TS 101 883 11 (H.323 Profile) and TS 101 884 12 (SIP Profile) of TIPHON Release 3. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

44、 the diagram below. Initially the H.323 1 and SIP 9 standards are used as references to study and verify the protocol profiles of TIPHON H.323, TS 101 883 11, and TIPHON SIP, TS 101 884 12. The results were used to generate the interoperability testing specifications. Output of this work may lead to

We recommend that interoperability testing is performed in a way that one entity Equipment Under Test (EUT) is teste
