Foreword This Technical Specification (TS) h
21、as been produced by ETSI Technical Committee Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN). Introduction The present document defines Release 2 of an anticipated series of releases of TISPAN NGN. Release 2 extends the capabilities of Release 1, enh
22、ances some Release 1 capabilities and provides some new services. The TISPAN NGN is described in terms of the content capabilities and this release (Release 2) is defined by the documentation set and the features that these support. The general objective of Release 2 is to extend Release 1 through e
23、nhancements and new services. The present document focuses on additional capabilities and services and continues to enable an NGN to be a flexible platform allowing future enhancements and releases. The TISPAN NGN is specified using a release mechanism. The present document provides an overview of t
24、he capabilities in the second release. No assumptions should be made about future releases. Throughout the present document, references to NGN are assumed to be references to TISPAN NGN unless otherwise indicated. ETSI ETSI TS 185 003 V2.3.1 (2009-06)61 Scope The present document provides an overvie
25、w of Customer Network Gateway (CNG) functional architecture and reference points and the way it interacts with an NGN, as described in ETSI TISPAN Release 1 and Release 2 standards (see ES 282 001 1). The present document describes architectural building blocks to be included in the CNG to support t
26、he interworking with an NGN, both at the transfer, transport and service layers. It also defines the reference points between the CNG internal architectural blocks involved and a CND. The WG5 does not address the layer 1 issues, as such studies refer to the AT - for informative references. Reference

ETSI ETSI TS 185 003 V2.3.1 (2009-06)83 Definitions and abbreviations 3.1 Definitions For the purposes of the present document, the following terms and definitions apply: CPN Device: device that is physically installed in t
42、he CPN allowing user access to network services; this can be a Customer Network Gateway with gateway functionalities towards the NGN, or a Customer Network Device being the end user terminal Customer Network Device (CND): CPN device enabling the final user to have direct access to services through a
43、 specific user interface NOTE: CNDs can be dedicated to the internet, conversational and audio-video services. But they could be also Consumer Electronics equipment and other devices which may have nothing to do with these premium services (e.g. services performing a content sharing within a CPN, ty
44、pically between a PC and a music system). Customer Network Gateway (CNG): CPN device acting as a gateway between the CPN and the NGN NOTE: CNG is able to perform networking functions from physical connection to bridging and routing capabilities (L1 to L3), but also possibly implementing functions re
45、lated to the service support (up to L7). Customer Premises Network (CPN): in-house network composed by customer network gateway, customer network devices, network segments, network adapters and nodes NOTE: Network segments are physical wired or wireless connections between customer premises network
46、elements); network adapters are elements performing a L1/L2 conversion between different network segments; nodes are network adapters with L3 routing capabilities. IMS CND: CND whose external behaviour complies with the IMS specifications NOTE: See 1, 2, 3, 4 and 5. “Multiple“ Play Services (can be:
47、 double, triple, quadruple etc.): delivery by a single service provider of different types of concurrent services to one or multiple users within the same CPN NOTE: Services can be categorized in the following way: data (e.g. Web browsing, best effort traffic etc.), person(s) to person(s) communicat
48、ion, entertainment. Non-IMS SIP IETF CND: SIP-based CND whose external behaviour conforms to RFC 3261 8 but do not fully conform to the IMS specifications Many scenarios are expected to provide one service from a service provider to a customer device (case of multiple service providers, one or sever
49、al CNG, etc.). They are presented within the TR 185 004 i.2 and TS 185 005 i.6. 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: ACS Auto-Configuration Server AKA Authentication and Key Agreement ALG Application Layer GatewayA-MGF Access-Media Gateway Function ARF Access Relay Function B2BUA Back-to-Back User Agent BC Broadcast ContentCLF Connectivity session Location and repository Function CND Customer Network Device CNG Customer Network Gateway CNG-ACF CNG-Admi
