PURPOSE:To attain smooth communication by transmitting the incoming signals to each radio base with time difference by a radio base station after deciding the signal incoming detection when the incoming signals are delivered from a mobile station continuously for a fixed period of time and longer. CONSTITUTION:When a control station is called from a mobile station, the sounds sent from the mobile station are delivered to a reception output terminal 19 through a radio device to call the control station. When the cell is continued, a squelch signal exists at a squelch terminal 20. Thus the signal incoming is detected by a reception timer 22 via a buffer amplifier 21. The timer 22 decides the signal incoming when the squelch signal continues for a fixed period of time or longer and drives a relay C23 for a fixed period of time for each radio base station with prescribed time difference. Thus a relay contact (c) is turned on, and the number of own radio base station is transmitted from a number transmitter 24. This number is displayed at the control station. A relay contact (c') is turned on after the number of the radio base station is transmitted. Then the sound signal sent from the mobile station is transmitted to the control station. |
