Abstract: A method and apparatus for managing mobility of a terminal by a first base station in a communication system. The first base station assigns a first address to the terminal located in a cell managed by the first base station and establishes a session to an external server that communicates with the terminal using the first address. If the terminal moves to a cell managed by a second base station different from the first base station, the first base station determines whether information about a second address assigned to the terminal by the second base station is received within a predetermined time. Upon receiving the information about the second address within the predetermined time, the first base station transmits data received from the external server to the terminal through the second base station using the information about the second address.
