  • METHOD AND APPARATUS FOR ROUTING CIRCUIT SWITCHED FALLBACK MESSAGING IN A WIRELESS COMMUNICATION SYSTEM
    Publication number: 20130028183
    Abstract: A multi-technology wireless communication system is provided that comprises a packet data network and a circuit switched network and that routes circuit switched fallback (CSFB) messages associated with a user equipment operating in the packet data network based on a circuit switched network access network identifier that identifies an Interworking Solutions function (IWS) of the circuit switched network that serves the user equipment. The circuit switched network access network identifier is maintained by a Node B of the packet data network and is provided to a serving Mobility Management Entity (MME) of the packet data network when implementing CSFB for the UE. The MME then selects an IWS of the circuit switched network for a routing of CSFB messaging based on the IWS identified in the circuit switched network access network identifier.
