摘要： 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.

摘要： Methods and apparatus are provided for supporting Local IP Access (LIPA) services to a User Equipment (UE). A network node receives a request for accessing a PDN which is identified by an APN of a service access point, from the UE. The network node determines whether the UE is permitted to access LIPA services via a CSG base station based on LIPA accessibility information. The network node determines whether requirements for connecting the UE to the LIPA services are met based on the LIPA accessibility information and device capabilities of a serving base station of the UE, when the UE is permitted to access the LIPA services. The LIPA services are activated for the UE, when the requirements for connecting the UE to the LIPA services are met.

摘要： A method and an apparatus for supporting mobility of a User Equipment (UE) are provided. When a UE moves into a Local Internet Protocol Access (LIPA)-enabled network or exits an LIPA-enabled network, the method is able to select an optimal user-plane node for the UE, provide optimal network routings and optimize network resource usage. For service continuity of the UE, when the UE performs remote access to an LIPA-enabled network from another network or when the UE moves into an LIPA-enabled network, the network re-selects an optimal user-plane node for the UE while keeping the remote service of the UE uninterrupted. When a UE moves from an LIPA-enabled network to another network, the network selects an optimal user-plane node for the UE while keeping the LIPA service uninterrupted. The method optimizes network resource usage and at the same time maintains the service quality perceived by the user.

摘要： A handover method for supporting terminal mobility is provided. Before a target core network node updates bearer information according to a target base station to which a User Equipment (UE) performs the handover, an access control determination procedure is added. According to the access control determination information provided by the target base station, if it is determined that the bearer supporting a Selected Internet Protocol (IP) Traffic Offload (SIPTO) or Local IP Access (LIPA) service is permitted to perform the handover, the target core network node updates the bearer information. If it is determined that the bearer supporting the SIPTO or LIPA service is not allowed to perform the handover, the handover failure is notified with respect to the bearer not allowed to perform the handover, and the bearer information is not updated, thus the wasted signaling resource and wireless resource are reduced. Alternatively, during the handover to the target network by the UE or after the handover to the target network, the bearer release or deactivation is performed for the bearer not allowed to perform the handover, so that the UE can re-initiate the bearer establishment process with respect to the bearer not allowed to perform the handover, thus an optimized bearer is established and the Quality of Service (QoS) is ensured.
