<p>A method for authenticating user terminal in IMS network, the method includes: with regard to user request, Service-Call Session Control Function(S-CSCF) entity creates the authentication challenge utilizing Digest Authentication Algorithm, and sends the authentication challenge to user terminal through Proxy- Call Session Control Function(P-CSCF) entity; the user terminal creates the authentication response utilizing Digest Authentication Algorithm according to the user key and associated parameters with said authentication challenge, and sends the authentication response to S-CSCF entity through S-CSCF entity; S-CSCF entity authenticates said authentication response utilizing Digest Authentication Algorithm according to HAI and associated parameters, if the authentication passes, determines that the user terminal is authenticated successfully, otherwise, determines that the user terminal is authenticated failure.</p> |
