Abstract
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.
