Abstract

Each mobile station is accommodated in a base station through a radio transmission path. A base station control device controls each base station. A mobile station is accommodated in a first base station. Each of the base stations notifies the mobile station of the condition of the communication resources of the base station, respectively. If the mobile station judges that it is advantageous to be accommodated in a second base station instead of the first base station, the mobile station makes a request for hand-off to the base station control device. The base station control device issues a hand-off command to both of the first and second base stations. Then, the mobile station is accommodated in the second base station.
