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?

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.
