If a mobile station or a base station considers it necessary to perform a hand-over, a new base station is selected as a hand-over receiving base station and a hand-over supplying base station is defined as a master base station whereas the hand-over receiving base station is defined as a slave base station depending on the master base station. The slave base station receives a signal from the master base station, compares it with a frame timing signal of the master base station, adjusts a frame phase of the slave base station into a frame phase of the master base station, and adjusts a frame phase of a down link line from the slave base station to the mobile station into a frame phase of a down link line from them aster base station to the mobile station. Further, the slave base station adjusts, in response to a signal from a mobile station targeted to be handed over, a frame phase of an up link line from the targeted mobile station to the slave base station so that a hand-over without break can be performed.
