The present invention provides a control method used in a communication system comprising a user equipment (UE), a gateway which the UE accesses, and a home subscriber server (HSS) storing database. The method comprises a step that the HSS provides information that identifies a gateway for being allocated to the UE on the basis of the database stored in the HSS, and a step that the UE accesses the allocated gateway based on the information provided by the HSS.
