Abstract
An apparatus and a method for supporting gateway node reselection in a communication system during a process in which a UE hands over from a source base station to a destination base station are provided. The apparatus includes the source base station for providing the destination base station with information for access control determination, the destination base station for making an access control determination according to the information provided by the source base station, the UE or a network for initiating a gateway reselection process according to the result of the access control determination. With the method, the reselection of Packet Data Network Gateway (PDN GW) or GGSN is implemented in a simple and reliable way by optimizing the existing signaling processes, in the case of user plane node reselection because UE changes position or handover to another base station.
