Apparatus and method for managing mobility of terminal in wireless communication system

摘要

An apparatus performs a method for managing mobility of a terminal by a Base Station (BS) in a wireless communication system. The method includes receiving information on whether a time for which a terminal had been located at a cell managed by a first BS before the terminal has moved to a cell managed by the BS is equal to or longer than a predetermined threshold. The method also includes controlling data transmission/reception of the terminal by using one of an address allocated to the terminal by the BS or an address allocated to the terminal by a home server according to whether the time for which the terminal had been located at the cell managed by the first BS is equal to or longer than the predetermined threshold.

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.
