METHOD FOR SUPPORTING PDN GW SELECTION

摘要

A method for supporting packet data network (PDN) gateway (GW) selection, comprising the following steps of: receiving by a mobility management entity (MME) a local route optimization service request information; searching by the MME the internet protocol (IP) address of a PDN GW which supports local route optimization according to the IP address of a PDN GW on home evolved node B (HeNB) (PDN GWh); sending by the MME a bearer request establishment message to the PDN GWh. The method of the present invention can ensure core network equipment to find PDN GW correctly while HeNB system supports local route optimization.

1. A method by a mobility management entity (MME) in a wireless communication system, the method comprising:
receiving, from a base station, a message related to a terminal; identifying whether an address of a gateway collocated with the base station is included in the message; and rejecting a connection establishment if the address is not included in the message and an access point name (APN) related to the terminal corresponds to local internet protocol access (LIPA).
