43、the general network architecture of the NGN. The model is depicted in figure 1. UE Visited NGN network Home NGN network e1 e5 Figure 1: General NGN network model Interface e1 is a user-network interface supporting attachment of user equipment to a network. The present document provides a description
44、 of the procedures applicable to this interface that is essentially independent from the layer 1 access technology being used. Interface e5 is a roaming interface, and is independent of the access technology. Interface e5 is used to provide a consistent method for the visited NGN network to communic
45、ate with the home NGN network. Figure 2 depicts the functional composition of the access network and the NGN core for the roaming scenario, where a UE obtains network access via a visited NGN network and authenticates back with the home NGN network.

This interface enables the UE to in
48、itiate authentication and authorization requests, as well as initiate requests for IP address allocation, DNS allocation, and other network configuration parameters in order to access the network. These requests are received by the AMF (Access Management Function). It is assumed that the IP edge in
49、the transport plane includes an ARF (Access Relay Function), which communicates with the UAAF (User Access Authorization Function) and NACF (Network Access Configuration Function) via the AMF. This interface enables the user equipment to provide user credentials (username/password, token, certificates, etc.) to the Network Attachment Subsystem (NASS) 25 in order to perform network access authentication and authorization. This interface may also enable the NASS to provide authentication parameter to the UE
