Foreword This Technical Specification (TS) has

18、been produced by ETSI Project Telecommunications and Internet Protocol Harmonization Over Networks (TIPHON). Introduction The present document describes the network architecture and the reference configurations that are necessary for the support of services and service capabilities defined for TIPHO

19、N Release 4. The TIPHON Release 4 definition and the corresponding relationship between the core deliverables is described in TR 101 301 V4.1.1 1. The present document builds upon the concepts embodied in TIPHON Release 3 8. These concepts which are applicable to network configurations based on the

20、range of functional and entities within the IP network, as described in the present document that are necessary to support the four scenarios of TIPHON Release 4. ETSI ETSI TS 101 314 V4.1.1 (2003-09) 6 1 Scope The present document defines the TIPHON network architecture and the reference configurat

21、ions that are necessary for: the delivery of telephone calls, which originate and terminate in IP networks; the delivery of telephone calls which originate in an Internet Protocol (IP) network and are delivered to Switched Circuit Networks (SCN); the delivery of telephone calls which originate in SC

22、Ns and are delivered in an IP network; and the delivery of telephone calls which originate in SCNs, routed through IP networks and delivered to SCN. These four scenarios are part of TIPHON Release 4. The architecture includes provision of information and facilities which are incidental to the delive

23、ry of telephone calls described above. The present document builds upon the concepts embodied in the TIPHON Release 3 network architecture and reference configurations described in TR 101 877 8. The present document is applicable to equipment fulfilling the roles of the functional groups identified

24、in TS 101 878 2; Terminal functional group, network functional group and Gateway functional group, and also to entities within the IP network that are necessary to support the four scenarios of TIPHON Release 4. 2 References The following documents contain provisions which, through reference in this

25、 text, constitute provisions of the present document. References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
