PURPOSE:To limit no-reception of control signals due to fading only to the no- reception of each period by transmitting continuously the incoming control signals to be transmitted to a mobile station from a base station via a radio circuit synchronously with a call signal given from a wire telephone circuit. CONSTITUTION:The fall of a call signal is detected by a call signal detecting circuit 11 of a base station 1. Thus a control circuit 13 stops the transmission of the bell ring signal. In this case, a mobile station 5 rings a bel until the next bell ring signal is received. If no signal is received by that time point when the next bell ring signal is received, a bell drive circuit 55 is controlled to stop quickly the ringing of a bell 56. As a result, the bell 56 of the station 5 is rung in the timing shown in a figure (c) and synchronously with a call signal shown by a figure (a). When the bell ring signal is transmitted and the bell ring signal is not received due to the fading, etc. at a point B1 of a figure (b), the station 5 detects the bell ring signal to be transmitted after a period and rings the bell 56. |
