Abstract
Systems and methods are presented for registering and routing incoming calls to a dual mode user equipment operable in a plurality of mobile communications networks. A latest registered network indicator is maintained and updated to indicate the network with which the user equipment has most recently registered, such as cellular network or IP-based network. Incoming calls are routed to the indicated network even where the user equipment was previously registered with a non-indicated network to resolve dual registration issues between different network types without having to attempt call delivery in both networks.
