PURPOSE:To pleasantly call a mobile station from a base station by allowing a base station to send a call control signal representing the number of times of generation of a call signal by a call means, and allowing a mobile station subject to address designation to activate the call means by the number of time represented by the call control signal. CONSTITUTION:The base station A inputs the address designation signal such as a vehicle number of a mobile station B for talking object by means of a key input means 1. A high frequency signal from the base station A is received by a transmission/reception circuit 11 via an antenna 10 at the mobile station B. The signal is supplied to a processing circuit 13, which reads a signal F thereby activating a buzzer 14 for the call. When a driver hearing a call signal tone by the buzzer 14 depresses a press-to-talk switch 15, the transmission/ reception circuit 11 sends a signal specifying the mobile station B. Thus, the base station A recognizes the mobile station B during talking. The voice signal from the base station A is transduced into a sound by a speaker 18 via a sound circuit 17.
