Abstract:
1. A method for traditional fixed network users accessing an Internet Protocol Multimedia Subsystem (IMS) domain, comprising the following steps: step 1: classifying fixed network users in a same region into a group, and configuring group information in an access gateway control function; step 2: when an access gateway initiates fixed network user registration to the access gateway control function, initiating group registration to an interrogating call session control function by the access gateway control function according to the group to which the fixed network users belong; step 3: interrogating to a home subscriber server about a service call session control function to which the group belongs by the interrogating call session control function, and registering the group to the service call session control function; wherein the group information comprises: a uniform public user identity of group users and information of group users in the group; wherein in step 2, the process of initiating group registration by the access gateway control function comprises: analyzing whether the fixed network users belong to the group in configured group information by the access gateway control function, if so, sending a session initiation protocol signalling which carries a group user uniform public user identity of the group to the interrogating call session control function, otherwise, registering according to a method for independent users accessing IMS domain in the current Internet.
