32、ay 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 specific user interface NOTE: CNDs can be dedicated to the internet, conversational and audio-vid

33、eo 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, typically between a PC and a music system). ETSI ETSI TR 185 007 V2.0.0 (2008-03) 7 Customer Network

34、 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-L3), but also possibly implementing functions related to the service support (up to L7). Customer Premises Ne

35、twork (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 elements); network adapters are elements performing a L1/L2 c

36、onversion between different network segments; nodes are network adapters with L3 routing capabilities. “Multiple“ Play Services (can be: 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. Serv

37、ices can be categorized in the following way: data (e.g. Web browsing, best effort traffic etc.), person(s) to person(s) communication, entertainment. 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: ACS AutoConfiguration Server ARF Access Relay Function

Figure 4.1 shows all the interfaces analysed in the present document. Figure 4.1: IMS CND connected to the NGN-IMS netwo

43、rk through a CNG 5 Transport Layer 5.1 Attachment 5.1.1 Protocols on e1Interface The e1interface is defined between the CND and the CNG-AtF. In comparison with e1interface, the e1may implement only a subset of functionalities and due to the fact that e1is inside the CPN some implementations can be e

44、xcluded. In the following clause some examples of e1usage are given. The CNG-AtF provides IP addresses (IPv4 or IPv6 format) to the CND through the CND-AtF, it may also send some configuration information for the CND (typically through DHCP options). The CNG-AtF gives private IP addresses to the CND

45、s if the CNG support NAT/NA(p)T function. ETSI ETSI TR 185 007 V2.0.0 (2008-03) 9 5.1.1.1 Hardware identities exchange In order to mutually exchange hardware identities between a CND and the CNG, it is strongly recommended to implement the DSL Forum specification TR-069 Amendment-1 1, Annex F (previ

46、ously TR-111). This specification indicates the usage of the DHCP option 125 to exchange identities. If the CND support the TR-069 that means the CND implement the e3reference point also, it is possible apply the following implementation. As defined in TR-069 1 (Table 36) the hardware identity of an

47、y device, either CNG or CND, is represented by the DeviceId, that is composed by the following three parameters: OUI Organizationally Unique Identifier of the device manufacturer. Represented as a six hexdecimal-digit value. ProductClass Identifier of the class of product for which the serial number

48、 applies. That is, for a given manufacturer, this parameter is used to identify the product or class of product over which the SerialNumber parameter is unique. SerialNumber Identifier of the particular device that is unique for the indicated class of product and manufacturer. As specified in TR-069

49、 (Annex-F Table 78): - the CND provides its DeviceId to the CNG by using DHCP Option 125, Sub-Option codes 1 (OUI), 2 (SerialNumber), 3 (ProductClass); - the CNG provides its DeviceId to the CND by using DHCP Option 125, Sub-Option codes 4 (OUI), 5 (SerialNumber), 6 (ProductClass). 5.1.1.2 Discovery of local SIP server within B2BUA The CND device can discover the SIP server using DHCP option 120 “SIP Server DHCP Option“ in case of IPv4 3. The CND device can discover the SIP server using DHCP option 21 “SIP Servers D
