PURPOSE:To prevent the deterioration in the speech quality by comparing a reception level of a position notice signal received from a stationary radio equipment whose position is already registered and from other stationary radio equipment and revising the registered position when the reception level of the latter is larger by a prescribed value or over. CONSTITUTION:After a notice monitor timer is set, e.g., a mobile radio equipment 3a checks whether the position notice signal is received from a stationary radio equipment 41 or other stationary radio equipments 41, 42 when the position notice signal with a prescribed level or over is received from any of the stationary radio equipments 41-43. Then the position notice signal from other stationary radio equipment is checked as to whether it is received at a larger level by a prescribed level or over than the signal from the stationary radio equipment registered already. When the level is received by a larger level with a prescribed value or over, since it represents that the stationary radio equipment moves to a new radio zone, the registered position is revised. Thus, the production level of a disturbing wave due to transmission or reception intermodulation is decreased to ensure the required speech quality. |
