If the strength of the signal transmitted from a remaining base station is larger than that from the active base station, the search control unitshifts to the confirmation mode, where the remaining base station is designated as a confirmation target remaining base station. Then, if the strength of the signal transmitted from the confirmation target remaining base station is larger than that from the active base station, a counter is incremented. If the counter value becomes a predetermined value R, a hand-off is performed to the remaining base station. In case that the strength of the signal transmitted from the confirmation target remaining base station becomes not larger than that from the active base station, the confirmation mode is terminated at that point to return to the normal mode.
