連絡信号を受信できるようにしたものである。Since emergency contact signals cannot be received during a call and can only be received between 9 calls, there are cases where emergency contact signals cannot be received. The emergency communication signal from the mobile station can always be received by setting the active radio to the communication channel and the backup radio to the control channel during 2nd communication. This is how it was done.

を受信し、緊急に通信を要求している移動局があること
を認識するシステム機能かある。Regional disaster prevention radio is broadly classified into a multi-channel wireless communication system that operates using one control channel and multiple call channels for transmitting and receiving call connection signals.This wireless communication system includes: By selecting a specific signal on the control channel from the mobile station to the base station for emergency contact in the event of an emergency, the base station can receive this signal between communications and notify the mobile station that is urgently requesting communication. Is there a system feature that recognizes that there is a problem?
この緊急連絡の信号は20秒間隔で最高11回すなわち
3分20秒間移動局から発信し続けるようになっている

よび統制通信には時間制限がなく9通話中は通話チャネ
ルに設定されるため、制御用チャネルの緊急連絡信号は
受信できなくなる場合があった。This emergency contact signal continues to be transmitted from the mobile station up to 11 times at 20 second intervals, that is, for 3 minutes and 20 seconds. When the base station enters the communication state, it can normally receive the emergency contact signal after 9 communications have been completed, since there is a time limit of 3 minutes in the case of general communications. However, since there is no time limit for simultaneous notification and control communication, and the communication channel is set during 9 calls, it may become impossible to receive the emergency contact signal on the control channel.
従来は、上記のように一斉通報および統制通信の場合に
は緊急連絡信号か受信できなくなる場合が生じるという
問題があった。従来は基地局が通信中には移動局からの
緊急連絡信号を受信できないのはやむを得ないものとし
ていた。Conventionally, there has been a problem in that in the case of simultaneous notification and controlled communication as described above, it may become impossible to receive emergency communication signals. Conventionally, it was considered unavoidable that a base station could not receive an emergency contact signal from a mobile station while it was communicating.
不発明は基地局が通信中であっても常に、制御用チャネ

When the base station makes a call to mobile station A, first, the control device sends a call signal 15 to the working radio. When the working radio device receives this signal, it sends out a calling signal 16 to the mobile station on the control channel. Call signal 15.
16 contains selective call information, and in the example shown in FIG. 8, it is assumed that mobile station A is called. Mobile station A, which has received the calling signal 16, sends out an ACK signal 17 indicating that it is ready to respond on the control channel, and switches to the speech channel according to the channel designation information included in the calling signal 16.
