Document Type and Number:

WIPO Patent Application WO/2017/007202

Kind Code:

A1

Abstract:

Provided are a method for deleting UE information by a mobility management entity (MME) of a local evolved packet core (EPC) in a wireless communication system, and an apparatus for supporting the same. The MME of the local EPC may receive a UE information delete request message from a base station and delete the UE information on all UEs within an area of the general base station. Provided are a method for removing an S1 interface between the general base station and the MME of the local EPC by the MME of the local EPC in a wireless communication system, and an apparatus for supporting the same. The MME of the local EPC may detect that S1 connection between the general base station and a general EPC is restored, transmit an S1 removal request message to the general base station, receive an S1 removal response message from the general base station, and remove transport network layer (TNL) association towards a neighboring base station. The local EPC may be included in a single base station. The MME may be included in the local EPC. The general base station does not include the local EPC.
