发明名称 SYSTEM AND METHOD FOR MOBILE COMMUNICATION
摘要 PROBLEM TO BE SOLVED: To prevent the radio wave of a mobile station device from exerting adverse influence on a peripheral device, etc., and to enable the mobile device to receive a call in a place where the radio wave of the mobile station device exerts adverse influence or in a use-prohibited place without manually turning on and off the power source of the mobile station device when the user enters or exist to/from such a place. SOLUTION: Sensors 102 and 103, provided nearby the entrance and the exit of the portable telephone use-prohibited place 101 in which the transmitted radio wave of the portable telephone set 105 exerts some adverse influence, detect the user of the portable telephone set 105 entering or exiting to/from the place through the entrance and exit. A transmission device 104 sends a 1st signal when the entry of the user into the user-prohibited place 101 through the entrance is detected, and sends a 2nd signal when the exiting operation is detected, with electric power large enough for the signals to reach the periphery of the entrance and the exit. The portable telephone set 105 is enabled to notify the user of termination without generating any sound when the received signal from the transmission device 104 is the 1st signal, but to originate a call, on the other hand, when the received signal is the 2nd signal.
