43、. Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Services and Protocols for Advanced Networks (SPAN). Introduction The approach being taken to standardization in NGN is as six projects: NGN1: Architecture, NGN2: QoS, NGN3: Service Platforms, NGN4: Network Ma

44、nagement, NGN5: Lawful Interception, NGN6: Security. Its aim is to allow much greater scope for competition through innovation in the design of equipment and services. Its aim is also to provide adequate standardization to facilitate the operation of services across interconnected networks, even net

45、works that use different technologies. The present document presents the initial core set of Service Capabilities envisaged to be required to enable service providers to offer services on TIPHON and UMTS networks that may safely interwork with existing PSTN and ISDN services while enabling more adva

46、nced services to be subsequently developed. ETSI ETSI TS 102 261 V1.1.1 (2003-09) 8 1 Scope The present document is an analysis of the mapping of concrete functional architectures as defined in UMTS IMS and MSF to the TIPHON release 3.0 call control architecture. Whilst developing a generic NGN refe

47、rence model, reference points and the requirements for protocols and interfaces for interconnection are identified. The objective of the present document is to verify implementation oriented architectures against the Release 3 architecture, as developed in EP TIPHON TS 101 314 6. This will highlight

48、 if there are incompatibilities between the architectures. This study will use the framework for interconnection reference points as defined by ITU-T SG13 in ITU-T Recommendation Y.140 50. Ideally, the generic reference model defines a reference architecture, which is technology independent. A funct

49、ional architecture for NGN study approaches this subject by considering a decomposed call control reference model and collecting functional entities into a simplified logical structure, and referencing possible implementations. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
