Abstract:
A system and method for allowing legacy circuit switched user equipment (CS UE) to operate via a packet-switch system, such as an IP Multimedia Subsystem (IMS) system, is provided. The mobility and session control aspects of communications with a legacy CS UE is separated. A user agent is placed in the receiving node (e.g., a home node B) that acts as the SIP agent for the CS UE for session control. An interworking function is provided to allow mobility between the macro CS network and the PS (e.g., IMS) network.
