A broadband wireless access communication system in which a subscriber station (SS) sends a serving base station (SBS) a handover request to neighbor base stations (NBSs) having a CINR satisfying a handover condition, in response to a handover scan request message, and performs the handover to a particular NBS that transmits a handover response. The SBS transmits the handover scan request message to the SS, sends a handover connection request to NBSs in an order determined by CINRs reported from the SS, and sends, to the SS, information on a particular NBS upon receiving a handover connection response with ACK information from the particular NBS. The particular NBS determines whether it can support handover of the SS, in response to the handover connection request, and sends the handover connection response with the ACK information to the SBS, if it can support handover of the SS.

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.
