ABSTRACT:
A handover method in a wireless communication system is disclosed. A serving base station transmits a handover request message to a base station controller in response to a handover request of a mobile station. The base station controller determines target base stations to which the mobile station can perform handover among target base stations in a list of neighbor base stations, and transmits a handover response message including the determination result information to the mobile station via the serving base station. The mobile station determines a target base station to which it will perform handover, and transmits a message indicating that it will perform handover, to the base station controller via the serving base station. The base station controller transmits a confirm message indicating that the mobile station will perform handover, to the determined target base station, and establishes a tunnel to the target base station. The mobile station registers itself in the target base station.
