    摘要： An authentication method of IP multimedia subsystems includes: after the P-CSCF receives a register message transmitted by the UE (s112), the P-CSCF queries the determined the CLF (s113) for the attach information of the UE in the access network to obtain a query result (s114), and transmits a register message carrying the query result to the I-CSCF (s115); the I-CSCF forwards the register message to the S-CSCF which is informed by the UPSF/HSS (s116, s117), the S-CSCF authenticates the UE according to the authentication mode obtained from the UPSF/HSS to obtain an authentication result (s118), and sends the authentication result to the UE (s119, s120, s121, s122, s123). In the invention, the UPSF/HSS of service layer determines the authentication mode for user, and the S-CSCF accomplishes the authentication process, so it is more reasonable. The invention further provides an authentication method that combine an authentication mode binding IMS service layer authentication and access layer authentication with other authentication mode, ensuring that the user can be authenticated correctly even in the case of the failure of authentication mode binding IMS service layer authentication and access layer authentication.
