(C urrently Amended) In a system for preventing a circuit switched, C S, domain call of a user equipment, UE, from being dropped during a handover procedure, where the UE registered with one of a plurality of Generic Access Network C ontrollers, GAN C s, based on Long-Term Evolution, LTE, and Generic Access Network, GAN, technology, where a Mobile Management Entity, MME, controls packet bearers of the C S domain call of the UE which involves the registered GAN C, where the registered GAN C holds a UE GAN registration context and the C S domain call for the UE, and when the UE moved towards a GSM EDGE Radio Access Network/UMTS Radio Access Network, GERAN/UTRAN the MME selected one of the plurality of GAN C s based on a GERAN/UTRAN cell identifier or a Location Area Identifier, LAI, associated with a location of the UE and transmitted the handover request to the selected GAN C, the selected GAN C comprising: a processor; and a memory that stores processor-executable instructions where the processor interfaces with the memory and executes the processor-executable instructions to: determine if the UE GAN registration context and the CS domain call for the UE are held therein; if yes, then handle the handover request for the CS domain call of the UE; [[and]] if no, then forward the handover request to other GAN C s which could possibly hold the UE GAN registration context and the CS domain call for the UE and the one of the other GAN C s which holds the UE GAN registration context and the CS domain call for the UE will handle the handover request for the CS domain call of the UE;_ and wherein the processor and the memory are com p onents of the selected GANC.
The selected GAN C of claim 35, wherein the processor adds an indicator to the forwarded handover request, where the indicator indicates that the forward handover request is from the selected GAN C and not the MME.
The selected GAN C of claim 35, wherein when the processor forwards the handover request to the other GAN C s and one of those GAN C s hold the UE GAN registration context and the C S domain call for the UE then the processor handles handover signaling between the MME and the one GAN C that holds the UE GAN registration context and the C S domain call for the UE.
