A base station BTS1 includes a mobile station-directing measuring/comparing section 171 for selectively outputting a hand-over request signal on the basis of data indicative of the received power level of a talk signal or packet signal 101 from a mobile station MS1. A base station control unit BSC includes a station arrangement information table 105, and selects in response to a hand-over request signal a supplementary base station SBTS1 that executes the hand-over and outputs an operation start command. The base station control unit also outputs a supplementary base station power measurement command when a first identification signal is outputted, and therefore the mobile station selectively outputs a supplementary base station measurement result signal on the basis of data indicative of the received power level of the first identification signal. The base station control unit further outputs a hand-over execute command. The supplementary base station includes a connection/disconnection control section 131 for generating a control signal in response to the operation start command and setting up a wireless channel to the base station control unit in response to the hand-over execute command and a start/stop control section 133 for outputting a start signal in response to the control signal so that the first identification signal is outputted.
