Abstract
A mobile user station periodically searches for a connectable access point and stores the address of a connectable access point that has been found in a master-station management table. When the mobile user station moves from one cell to another under these conditions, the state of communication with the old access point deteriorates. When the state of communication with the old access point deteriorates to such a degree that it becomes necessary for the mobile user station to connect to a new access point, the mobile user station sends a connection request to the access point stored in the master-station management table and performs communication via the new access point. As a result, when connection to a new access point becomes necessary owing to movement of the mobile user station between cells, the changeover between access points can be performed quickly without searching for an access point.
