HANDOFF OF A MOBILE STATION BETWEEN PACKET-SWITCHED AND CIRCUIT-SWITCHED WIRELESS DOMAINS

摘要

A first mobility management entity (MME) is configured to cooperate with a first access network controller to provide a circuit switched service to a mobile station while the mobile station is attached to a packet switched wireless access network in a first coverage area. A second MME is configured to cooperate with the first access network controller to provide a circuit switched service to the mobile station when the mobile station has moved from the first coverage area to the second coverage area. A home subscriber system is operated to provide, to the second MME, information identifying the first access network controller as serving the mobile station to enable the second MME to initiate handoff of the mobile station from the packet switched wireless access network to the circuit switched wireless access network.

主权项

1. At least one non-transitory processor-readable medium carrying instructions for execution by at least one processor of a first mobility management entity associated with a packet-switched wireless access network, the instructions comprising:
instructions executable by the at least one processor to receive information associated with a mobile station being served by the first mobility management entity, wherein the information identifies a serving generic access network controller for the mobile station, the serving generic access network controller being used to provide a circuit-switched service to the mobile station while the mobile station is attached to the packet-switched wireless access network; instructions executable by the at least one processor to initiate a handoff of the mobile stations from the packet-switched wireless access network to a circuit-switched wireless access network, the circuit-switched wireless access network being in a region served by a second generic access network controller different from the serving generic access network controller; and instructions executable by the at least one processor in performing the handoff to use the information to identify the serving generic access network controller to communicate handoff-related messaging to the serving generic access network controller to cause provision of the circuit-switched service to be handed off from the serving generic access network controller to the second generic access network controller.
