Abstract
The present invention discloses a security management method and a security management system for a WAPI terminal accessing an IMS network. The method comprises: an authentication service unit (ASU) sending, under the circumstance that an access point and the WAPI terminal pass the verification of the ASU, a security information request message to a home subscriber server (HSS) (S302); the HSS setting security information corresponding to the IMS account information of the WAPI terminal as access layer security after receiving the security information request message from the ASU (S304); a proxy-call session control function (P-CSCF) receiving an IMS login request message from the WAPI terminal, inquiring about the security information of the WAPI terminal through the HSS, and allowing the WAPI terminal to execute an IMS service flow under the circumstance that the security information of the WAPI terminal is the access layer security (S306).
