Multi-access authentication method and system in next generation network

Abstract

The disclosure provides a method for multi-access authentication in Next Generation Network (NGN), which includes: a network side authentication center generates an authentication vector after receiving user terminal information from a user terminal, wherein the user terminal information includes subscription information and multi-access information of the user terminal; the user terminal performs authentication on the network side after receiving an authentication request from the network side authentication center, and generates keying material and network side authentication information upon successful authentication, and sends the network side authentication information to the network side authentication center, wherein the authentication request includes authentication information; the network side authentication center performs authentication on the network side authentication information using the authentication vector, generates keying material according to the multi-access information of the user terminal upon successful authentication, and inform an access forwarding functional module of the keying material; the access forwarding functional module encrypts and decrypts access service information of the user terminal according to the keying material. The disclosure also provides a system of the method. The disclosure enhances the efficiency with which the user terminal accesses the network.

Description

technical field [0001] The invention relates to authentication technology, in particular to a multi-access authentication method and system in a next generation network (NGN, Next Generation Network). Background technique [0002] NGN is receiving more and more attention as an evolving network framework based on packet switching. International Telecommunication Union Telecommunication Standardization Bureau (ITU-T, Telecommunication Standardization Sector of the International Telecommunications Union) and other regional standard organizations such as European Telecommunications Standards Institute (ETSI, European Telecommunications Standards Institute), World Wireless Communication Solutions Alliance (ATIS, The Alliance for Telecommunications Industry Solution) and others have conducted extensive research and standardization work on NGN framework models, services and related fields. [0003] NGN can support multiple network access. When the mobile user terminal performs mu...

Problems solved by technology

[0005] However, this increases the signaling interaction between the terminal and the NGN network, which undoubtedly hinders the speed of the user terminal's access to the network, and causes a great waste of resources for the air interface resources that are already resource-intensive.
