METHOD AND APPARATUS FOR RELEASING USER EQUIPMENT CONTEXT IN WIRELESS COMMUNICATION SYSTEM

WIPO Patent Application WO/2012/134111

A3

A method and apparatus for releasing a user equipment (UE) context in a wireless communication system is provided. A home evolved NodeB (HeNB) gateway (GW)/X2-proxy receives a UE context release message, forwards the UE context release message to a source eNB; and releasing the UE context of the corresponding UE. The source eNB and the target eNB may be connected through an indirect X2 interface. Or, a home evolved NodeB (HeNB) gateway (GW)/X2-proxy receives a UE context release request message from a source eNB, and releases the UE context of the corresponding UE based on the UE context release request message. The source eNB and the target eNB may be connected through a direct X2 interface.
