17、ttee Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN). ETSI ETSI TR 182 031 V3.1.1 (2010-09) 51 Scope The present document covers a use case analysis for the interaction of the TISPAN Resource and Admission Control Sub-System (RACS) with the Customer
18、Premises Network (CPN), as well as an analysis of required functional entities, reference points and information flows. Furthermore, requirements for interworking with in-home QoS control mechanisms are studied. The study concludes with a recommendation on the way, or ways, how RACS and CPN should i
19、nteract and interface, i.e. on one or several interworking architecture(s) proposal(s), taking into account security and privacy aspects. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

40、nce scenarios where the described CPN-RACS interaction is applicable and use cases from the viewpoint of the RACS. The reference scenarios are studied regarding access network configuration options and ways to connect end devices in the CPN to the NGN. The derived use cases from the view of the RACS
41、 can be split into resource and admission control and policy installation processes, applicable on access lines and inside CPNs. 4.1 Reference scenarios and use cases In the TISPAN NGN functional architecture described in ES 282 001 i.1, a User Equipment (UE) attaches directly to the NGN. TS 185 003
42、 i.4 defines an enhanced architecture where a Customer Network Gateway (CNG) can act either as a UE in case it has e.g. an embedded SIP client or where Customer Network Devices (CNDs) with embedded clients connect through a CNG to the NGN. In the latter case, depending on the use of signalling proxi
43、es in the CNG and whether the CNG works in routed or bridged mode, the reference points to the NGN are either local ones inside the Customer Premises Network (CPN) as defined in TS 185 003 i.4 or the same ones as described in ES 282 001 i.1. Figure 1 depicts this architecture. ETSI ETSI TR 182 031 V
44、3.1.1 (2010-09) 8CNDCNDCNGCPN NGNFigure 1: Baseline architecture for NGN access including a CPN This study makes the following basic assumptions: 1) A single CNG exists in the CPN as central gateway towards the NGN. 2) The CNG is reachable from the NGN on IP layer, e.g. for remote management purpose
45、s. 3) The CNG operates in routed mode. 4.1.1 Reference scenarios This clause details reference scenarios for access configuration scenarios and for connection scenarios towards the NGN on a NGN reference point level. 4.1.1.1 Access configuration scenarios The CNG connects to an access node on the NG
46、N side as described in ES 282 001 i.1. The following two scenarios cover current fixed line broadband access technologies. CNGCNGCNGCNGCNGCNGAccess NodeAccess NodeFigure 2: Configuration scenarios in access segment ETSI ETSI TR 182 031 V3.1.1 (2010-09) 9The different options as shown in figure 2 are
47、: 1) Each CNG has a dedicated, non-shared access line on its own. This is the case for e.g. xDSL access or FTTH access with dedicated fibres. 2) A number of CNGs from different customers share a common access line segment. This scenario covers e.g. shared PON access. NOTE: In case PON is used to fee
48、d access nodes, option 1) applies. Each CNG has its dedicated access line. 4.1.1.2 NGN connection scenarios For signalling and multimedia flows, three relevant options to connect to the NGN are possible according to TS 185 003 i.4. The three reference scenarios are shown in figure 3 with the corresp
49、onding reference points for signalling in the case of SIP signalling.
