Abstract To prevent speech interruption at switch-back by decreasing a speech interruption time in the case of hand-over. SOLUTION: Signal reception quality is detected (104) intermittently (102) during a speech (100). In the case a high speed hand-over processing criterion is not satisfied as a result (122), while keeping radio connection with respect to a speech from a radio connection destination CS (stationary station) so far, remaining transmission reception systems not used for a speech are used to detect other CS (124) and to execute calling procedures (128-138) for establishment of the radio connection with the CS thereby reducing a speech interruption time. In the case of switch-back, the similar procedure is executed and speech interruption due to switch-back operation can be prevented during high speed movement.
