METHOD AND SYSTEM FOR REALIZING MOBILITY MANAGEMENT OF EVOLVED PACKET CORE NETWORK

摘要

Disclosed is a method for realizing mobility management of an evolved packet core (EPC) network. A first control network element addresses a second control network element according to an identification or address information of the second control network element sent by a first MME, acquires a PGW address and TEID information of a PGW allocated by the second control network element, and sends to the second control network element a first SGW address and TEID information of a first SGW allocated thereby; the first control network element sends to the first SGW flow table information carrying the PGW address and the TEID information of the PGW; and the second control network element sends to the PGW flow table information carrying the first SGW address and the TEID information of the first SGW. Also provided is a system for realizing mobility management of an EPC network. Coordination problems of two control network elements caused by the change of the control elements resulting from the movement of a UE can be solved by the solution of the embodiments of the present invention.
