Summary:PROBLEM TO BE SOLVED: To provide an automatic switching system which can automatically switch the call termination notifying system at the entrance of a prescribed space to provide an effect that the ringing tone of the mobile phone is suspended to sound in the space. SOLUTION: The control signal transmitters 4, 7 for generating a signal in which a control signal is superimposed are provided on the inside and outside of the entrance 3 of a space 1. When the mobile device enters the space 1, the control signal enters a control section of the mobile phone 6 to switch the ringing tone to vibration or the like. On the contrary, when the mobile device goes out from the space 1, the call termination notifying system is switched to the original condition.
