1. A method of managing mobility of a terminal by a second base station (BS) in a wireless communication network, the method comprising: allocating a second local address to a terminal if the terminal moves from a first cell into a second cell of the second BS, wherein a session has been established between the terminal and an external server using a first local address allocated by a first BS; receiving information of a dwell time for which the terminal was located in a first cell of the first BS; and establishing a session between the terminal and a second external server using the second local address if the dwell time is equal to or longer than a predetermined threshold, wherein a local address is valid for time in which the terminal is located in a cell of a BS allocating the local address to the terminal, and a core address is allocated by a home server upon an initial access of the terminal to the network and valid for time in which the terminal is connected to the network regardless of a position of the terminal.
