Features.

本発明の無線通信システムによれば、受話側の音量調整ボリュームの設定値に関わり無く、メッセージの通知が可能であるため、緊急時の通信などを聞き逃すことのない無線通信システムを提供できる。   According to the wireless communication system of the present invention, a message can be notified regardless of the set value of the volume adjustment volume on the receiver side, so that it is possible to provide a wireless communication system that does not miss an emergency communication.

本発明による、無線通信システムの実施の形態について図面を用いて説明する。図1は、本発明の無線通信端末の構成を示すブロック図である。制御信号設定部10および音量調整部17は、それぞれ、プロセッサ20および22とメモリ21および23とから構成されている。図2は、音声信号列の前に付与される制御信号列を示す制御信号フォーマットである。   Embodiments of a wireless communication system according to the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a wireless communication terminal of the present invention. The control signal setting unit 10 and the sound volume adjusting unit 17 are composed of processors 20 and 22 and memories 21 and 23, respectively. FIG. 2 is a control signal format showing a control signal sequence given before the audio signal sequence.

まず無線通信端末において、図2に示す通信モードを緊急通信とした場合について説明する。通信モードで緊急モードが選択されると、図1の制御信号設定部10のプロセッサ20は、メモリ21から、指定された通信モードの制御信号である緊急通信のフォーマットを取り出して、ベースバンド部11の制御信号列にセットする。音声調整値は、この操作に付随して自動的に、緊急通信の音量調整値にセットされる。ベースバンド部11でセットされた一連の制御信号列は、音声信号列と共に、送信部12から送信される。一般的には、通常通信は操作上デフォルトでセットされており、この場合は、音量調整値もデフォルトで無調整となっている。   First, a case where the communication mode shown in FIG. When the emergency mode is selected as the communication mode, the processor 20 of the control signal setting unit 10 in FIG. 1 takes out the emergency communication format that is the control signal of the designated communication mode from the memory 21, and the baseband unit 11 Is set to the control signal sequence. The audio adjustment value is automatically set to the emergency communication volume adjustment value in association with this operation. A series of control signal sequences set in the baseband unit 11 is transmitted from the transmission unit 12 together with the audio signal sequence. In general, normal communication is set as a default for operation, and in this case, the volume adjustment value is also unadjusted by default.

次に無線通信端末が、緊急通信を受信した場合について説明する。図1の制御信号処理部14は、受信部13の受信信号から音声信号と制御信号を分離し、制御信号を音量調整部17へ送る。音量調整部17のプロセッサ22は、受け取った制御信号とメモリ23の制御信号データから緊急通信を判断し、セットされている緊急通信の音量調整値で音声増幅回路18の音声出力を制御する。このとき、音声増幅回路18の音声レベルは、直前にセットされていたレベルとは無関係に、緊急通信の音声調整値にセットされる。スピーカ19は、音声増幅回路18の音声出力により駆動される。通常通信においては、音声調整値はデフォルトで無調整となっているため、ボリューム15の回転量で決まる音声レベルのアナログ値が、アナログ・ディジタル変換部16でデジタル信号に変換され、音声調整部17を介して音声増幅回路18を制御している。   Next, a case where the wireless communication terminal receives emergency communication will be described. The control signal processing unit 14 of FIG. 1 separates the audio signal and the control signal from the reception signal of the reception unit 13 and sends the control signal to the volume adjustment unit 17. The processor 22 of the volume adjustment unit 17 determines emergency communication from the received control signal and control signal data in the memory 23, and controls the audio output of the audio amplification circuit 18 with the set volume adjustment value of emergency communication. At this time, the voice level of the voice amplifier circuit 18 is set to the voice adjustment value for emergency communication regardless of the level set immediately before. The speaker 19 is driven by the sound output of the sound amplifier circuit 18. In normal communication, since the sound adjustment value is not adjusted by default, the analog value of the sound level determined by the rotation amount of the volume 15 is converted into a digital signal by the analog / digital converter 16 and the sound adjuster 17 The audio amplifier circuit 18 is controlled via

次に無線通信端末が、図2の一斉同報通信モードでデータを送信した場合の、基地局の機能について説明する。図3は、本発明による基地局の構成を示すブロック図である。通信制御部32は、プロセッサ35とメモリ36とから構成されている。   Next, the function of the base station when the wireless communication terminal transmits data in the simultaneous broadcast communication mode of FIG. 2 will be described. FIG. 3 is a block diagram showing a configuration of a base station according to the present invention. The communication control unit 32 includes a processor 35 and a memory 36.

図3の制御信号処理部31は、受信部30の受信信号から音声信号と制御信号を分離し、制御信号を通信制御部32へ送る。通信制御部32のプロセッサ35は、受け取った制御信号とメモリ36の制御信号データから一斉同報通信と判断し、メモリ36に登録されている業務用無線通信端末に向けて一斉に送信を開始すべく、ベースバンド部33の制御信号列をセットする。このとき音声調整値は、この操作に付随して自動的に、一斉同報の音量調整値にセットされる。ベースバンド部33で整えられた制御信号列は、音声信号列と共に送信部34から送信される。この送信データを受けた無線端末は、図1で説明した緊急通信の受信の場合と同様の手続で通話がなされる。   The control signal processing unit 31 in FIG. 3 separates the audio signal and the control signal from the reception signal of the reception unit 30 and sends the control signal to the communication control unit 32. The processor 35 of the communication control unit 32 determines simultaneous broadcast communication from the received control signal and the control signal data in the memory 36 and starts transmission to the commercial wireless communication terminals registered in the memory 36 at the same time. Therefore, the control signal sequence of the baseband unit 33 is set. At this time, the audio adjustment value is automatically set to the broadcast volume adjustment value accompanying this operation. The control signal sequence arranged by the baseband unit 33 is transmitted from the transmission unit 34 together with the audio signal sequence. The wireless terminal that has received the transmission data makes a call in the same procedure as in the case of receiving the emergency communication described with reference to FIG.

以上説明したように、この無線通信システムによれば、受話側の音量調整ボリュームの設定値に関わり無く、優先度に応じたメッセージを自動設定された音声出力で通知できる。従って、通信モードの種類、音量調整値の設定については、本実施例に限定されない。また緊急通信が終了すると、直前にセットされていた音声レベルに、自動的に再セットすることも可能である。さらに、無線通信端末の制御信号設定部10および音量調整部17のプロセッサ20および22、メモリ21および23を、1つのプロセッサおよびメモリで構成することも可能である。   As described above, according to this wireless communication system, a message corresponding to the priority can be notified by automatically set voice output regardless of the set value of the volume adjustment volume on the receiver side. Accordingly, the type of communication mode and the setting of the volume adjustment value are not limited to the present embodiment. When the emergency communication is finished, it is possible to automatically reset to the voice level set immediately before. Furthermore, the processors 20 and 22 and the memories 21 and 23 of the control signal setting unit 10 and the volume adjusting unit 17 of the wireless communication terminal can be configured by one processor and memory.

本発明は、受信側の音声レベルの設定状況に関わり無く、送信側の通信の重要度に応じて受信側の受信音量レベルを自動的に設定する必要がある通信網に、利用することが可能である。   The present invention can be used for a communication network in which the reception volume level on the reception side needs to be automatically set according to the importance of communication on the transmission side regardless of the setting state of the audio level on the reception side. It is.
