Embodiment Construction

[0053] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0054] In NASS, CNG can work in routing mode and bridging mode, and the processing flow of the present invention is slightly different in these two working modes, and the two cases will be described respectively below.

[0055] 1. CNG works in routing mode

[0056] At this time, both user access authentication and IP address allocation are initiated by CNG, and the processing flow is shown in Figure 2.

[0057] 1. CNG initiates an access request to the network, ARF (Access Relay Function) realizes the relay function of the access request, and inserts the logical access identifier of CNG access, such as device node identifier + port number + ATM VPI / VCI or device Node ID + port number + Ethernet VLAN, etc.

[0058] The CNG access request protocol may be DHCP or PPP, and the logical access identifier may be carried by an option or attribute of the adopte...

Abstract

This invention discloses one next generation network sub system interacting information method, which comprises the following steps: in router type, user gate sends interface require to sub system with interface circuit logic interface label to get logic interface label and to send logic label to user network gate after success; terminal device gets logic label from user gate to send or register call on control sub system with logic interface label; business control sub system receives calls records signal logical interface labeled sends user information require to sub system.

Description

technical field [0001] The present invention relates to the technical field of Next Generation Networks (NGN, Next Generation Networks), in particular to a method for exchanging user information between different subsystems in this technical field. Background technique [0002] At present, TISPAN (Telecommunications and Internet converged Services and Protocols for Advanced Networking committee), as a European telecommunications standard organization, is formulating the architecture of the future NGN network. NASS (Network Attachment Subsystem) is located in the transmission control sublayer of TISPAN NGN and is completed Subsystem for network attachment information management. The functional architecture of NASS is shown in Figure 1. It is mainly used for user terminal equipment IP address and parameter allocation, network access authentication management, user location information location and storage, and provides relevant user location information for the service control...
