Method and apparatus for supporting user equipment mobility in a wireless communication system

摘要

Methods are provided for supporting mobility of a UE in a system without an HeNB GW. An S1 setup request message is sent to an MME by an HeNB. The S1 setup request message includes version information of the HeNB. An RRC connection is established between the UE and the HeNB. An initial UE message is sent from the HeNB to the MME. An NAS message is sent from the UE to the MME. An establish bearer request message is sent from the MME to a corresponding SGW based on an IP address of an LGW. The IP address of the LGW is obtained by the MME through the S1 setup request message. An establish bearer response message is sent from the LGW to the SGW in response to the establish bearer request message. The establish bearer response message is sent from the SGW to the MME.

1. A method for supporting mobility of a user equipment (UE) by a mobile management entity in a wireless communication system, the method comprising the steps of:
obtaining, at the mobile management entity, version information of a base station; obtaining, at the mobile management entity, subscription information of the UE; estimating, at the mobile management entity, a service type invoked for connection between the UE and the base station based on the obtained version information and the obtained subscription information; establishing, at the mobile management entity, UE context information indicating the estimated service type; receiving, at the mobile management entity, a handover request of the UE from the base station; and determining, at the mobile management entity, whether to allow the received handover request based on the service type indicated by the UE context information, wherein the service type is one of a local internet protocol access (LIPA) and a selected internet protocol traffic offload (SIPTO).
