Foreword This Technical Specification (TS) has been produced by ETSI Project Telecommunications and Internet Protocol Harmonization Over
29、Networks (TIPHON). Introduction EP TIPHON has taken an initiative to harmonize with the 3GPP UMTS system, and the IP Multimedia Subsystem (IMS) in particular. This task involves identifying the differences between the two systems, with a view to identifying how to harmonize the approaches. The resul
30、ts of a gap analysis between TIPHON Release 3 and 3GPP UMTS Release 6 are described in the present document. This analysis is then used as an input to other documents forming part of the harmonization framework. These documents are identified as follows: TS 102 283 16 introduces new service capabili
31、ties required, which are missing in TIPHON Releases 3 and 4, to achieve harmonization with 3GPP. TS 101 315 3 contains proposals derived from studies into interworking and harmonization between TIPHON and 3GPP service architectures to identify the extensions and additions to the TIPHON Release 3 and
32、 future Release 4 Deliverable on the Application of TIPHON Functional Architecture to inter-domain services. TS 101 314 1 contains proposals for extensions and additions to the TIPHON Release 3 and future Release 4 Deliverable on Network Architecture and Reference Points. The extensions are based on
33、 the studies from 00003. TS 101 882 17 contains proposals for extensions and additions to the TIPHON Release 3 and future Release 4 Deliverable on the Protocol Framework Definition.ETSI ETSI TS 102 285 V1.1.1 (2003-11) 7 1 Scope The present document provides a comparison between TIPHON Releases 3 an
34、d 4 and 3GPP UMTS Release 5 system specifications (concentrating on IMS) with a view to harmonize the two. It provides a gap analysis between the two systems, and identifies actions to be taken to resolve any gaps, and achieve harmonization between the two approaches. 2 References The following docu
