Abstract:
An embodiment of the present invention is a method for support of Circuit Switched (CS) fallback in an Evolved Packet System (EPS), said support including moving a User Equipment (UE) from an evolved Radio Access Network (RAN) to a legacy RAN for access to CS domain services, and moving back said UE from said legacy RAN to said evolved RAN at termination of said CS domain services, said support including moving back said UE to said evolved RAN in the Public Land Mobile Network (PLMN) that was serving said UE over said evolved RAN before moving said UE to said legacy RAN.
