More Information
Summary:An automatic mode switching system for mobile stations, using weak radio waves (5,8) in changing the ringing call-arrival informing mode to the silent call-arrival informing mode, or in putting the mobile station in a selected condition of "transmission-and-reception ceased", "transmission ceased", "phone-conversation inhibited", "electric power off" or such like in the phone-conversation inhibited place. It includes first (7) and second (4) control signal generators positioned on the inside and outside of the entrance (3) of the closed space (1). Each control signal generator has at least inputting means for inputting control conditions according to which the mobile station is permitted to work, memory means for storing the contents of control condition; and transmitting means for transmitting the control signals representing the control condition. When getting in the closed space the mobile station (6) receives via its antenna the radio wave (5) carrying the control signals from the first control signal generator (4) to make the mobile station to switch its working mode from the ringing to silent mode, thereby informing the call arrival by means of medium other than sound. When getting out of the closed space (1) the mobile station receives via its antenna the radio wave carrying the control signals from the second control signal generator to make the mobile station to switch its working mode from the silent to ringing mode, thereby informing the call arrival by means of sound.
