To provide a system for limiting the use of mobile communication apparatuses in a public place such as the interior of a train.

A repeater is placed between a base station and the mobile communication apparatus and the relaying apparatus transmits a manner mode channel (MCH) to the mobile communication apparatus to modify the operating mode of the mobile communication apparatus. Upon the receipt of the MCH, the mobile communication apparatus performs deactivation of ringing of a ringer tone or the like and decreases a transmission power level to a level required for the communication with the relaying apparatus.
