Abstract
The present invention discloses a method and system for traditional fixed network users accessing Internet Protocol Multimedia Subsystem (IMS) domain, both of the method and system can classify fixed network users in a same region into a group, and configure group information in an access gateway control function; when an access gateway initiates fixed network user registration to the access gateway control function, the access gateway control function initiating group registration to an interrogating call session control function according to the group to which the fixed network users belong; the interrogating call session control function interrogates to a home subscriber server about a service call session control function to which the group belongs, and the group is registered to the service call session control function. The method and system of the present invention greatly reduce the generation of register messages, increase the registration efficiency and overcome the defects that there is a long registration time delay and a great traffic when the fixed network users access IMS domain in the prior art.
