Abstract
Official abstract text for this publication.
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.
