PROBLEM TO BE SOLVED: To automatically control a radio equipment power source without operating a radio equipment by a carrying person. SOLUTION: Electric wave from the antenna 12 of a pre-existing base station 11 is interrupted inside a shelded room 3, power source control electric wave is previously transmitted from a base station antenna 10 instead of waiting electric wave from the pre-existing base station 11 inside the shielded room 3 and the radio equipment 2 receives power source control electric wave instead of waiting electric wave. The radio equipment 2 processes power source interruption by a radio equipment power source control means by receiving the reception of power source control electric wave. When the radio equipment 2 is under calling, communication electric wave from the antenna 12 of the pre-existing base station is not obtained so that the communication electric wave of another channel is previously prepared instead of communication electric wave which is transmitted from the pre-existing base station antenna 12 inside the shielded room 3 and, then, a call can be continued. The change-over of wave is made to be a chance for executing the processing of the power source interruption of the radio equipment 2 by the radio wave equipment power source control means. |
