PURPOSE:To allow other terminal mobile station to confirm dialing even when a radio control station is in usual communication with a terminal mobile station by allowing a radio equipment for emergency communication to be used even when usual communication is sent/received. CONSTITUTION:When a call comes from a mobile station 200 to a radio control station 100 and a usual communication radio equipment 112 is in use, the radio equipment 112 sends a signal to the mobile station 200 to be transited to a frequency of a prescribed communication channel, and the radio control station 100 itself transits to the frequency and the usual communication is implemented with the mobile station 200. When the usual communication radio equipment 112 is busy with other mobile station, an emergency communication radio equipment 114 implements usual call processing and a station number of the mobile station 200 included in a call signal of the usual communication and a time when the call is received are displayed on a display section 123 of a control console section 120. When the call from the mobile station 200 indicates emergent communication, the emergent communication radio equipment 104 implements reception processing of an emergent call and the presence of an emergent call is displayed on the display section 123. |
