SECURITY MANAGEMENT METHOD AND SYSTEM FOR WAPI TERMINAL ACCESSING IMS NETWORK

摘要

A security management method and system for the WLAN Authentication Privacy Infrastructure (WAPI) terminal accessing IP Multimedia Subsystem (IMS) network. The method includes that: Authentication Service Unit (ASU) sends a security information request message which carries the IMS account information of the WAPI terminal to Home Subscriber Server (HSS) under the circumstances that the access point and the WAPI terminal passes the authentication of ASU (S302); after receiving the security information request message from ASU, HSS sets the security information corresponding to the IMS account information of the WAPI terminal to access layer security (S304); Proxy-Call Session Control Function (P-CSCF) receives the IMS register request message from the WAPI terminal, inquires the security information of the WAPI terminal through HSS, and permits the WAPI terminal executing the IMS service flow under the circumstances that the security information of the WAPI terminal is access layer security (S306).
