Wireless LAN terminal, wireless LAN base station, and wireless LAN system including them and wireless hand-off method

摘要

When a wireless LAN terminal moves to outside the cell of a first wireless LAN base station and it has entered a cell overlap area between a second wireless LAN base station cell and a third wireless LAN base station cell, it receives from the second and the third wireless base station, respectively, the network address of a network to which the second wireless LAN base station is allocated and the network address of a network to which the third wireless LAN base station is allocated. The wireless LAN terminal starts to perform a communication with the second wireless LAN base station that has transmitted on with respect thereto the same network address as that network address of the network, having the first wireless LAN base station kept in connection therewith, that that terminal holds therein.
