一种ip多媒体子系统网络鉴权系统及方法

Network authentication system and method for IP multimedia subsystem

Abstract

The invention discloses an IMS right-identification network system by adding a interface supported right-identification signaling on IMS network, which comprises: a MS for right-identification calculation, a HLR, and said IMS network to transfer parameter and compare calculation result. It also provides the method: after receiving the register request from MS, IMS acquires calculation result of parameter from HLR to save the result and send parameter to MS; MS calculates and sends right-identification result to IMS network; IMS decides whether the results accords from MS and HLR. This invention is simple and has well reliability.
本发明公开了一种IMS网络鉴权系统,在IMS网络增加一个支持鉴权相关信令的接口,系统包含:用于进行鉴权计算的MS和HLR以及用于传递鉴权相关参数和比较鉴权计算结果的IMS网络。本发明同时提供了一种IMS网络鉴权方法,IMS网络在接收到MS发起的注册请求后,向HLR获取鉴权计算结果或鉴权相关参数,保存该鉴权计算结果并将鉴权相关参数发送给MS,MS根据此参数计算出鉴权计算结果并将其发送给IMS网络,IMS网络判断MS和HLR发送的鉴权计算结果是否一致。本发明对原有电路域的网络设备没有改动,只在IMS网络上增加一个与HLR进行通信的接口,不需IMS网络实体支持传统鉴权算法,实现简单,且保证了鉴权的可靠性和成功率。
