本発明の無線通話システムは、シンプレックスモードで動作する業務用無線ネットワークを構成する送信側無線端末と受信側無線端末とからなる無線通話システムにおいて、送話側無線端末は受話側無線端末を選択可能とし、受話側無線端末が、送話側無線端末から送られてきた音声データの通話信号レベルに応じて音声レベルの調整を行い、調整された音声レベルの調整値データを蓄積する手段と、前記送話側無線端末に受信が途切れた瞬間に音声レベルの調整値データを返信する手段とを備え、前記送話側無線端末が、返信された前記調整値データに従って、マイクレベルを調整する手段を備え、前記受話側無線端末と前記送話側無線端末とが直接通話を行うことを特徴とする。 The radio call system of the present invention is a radio call system comprising a transmitting side radio terminal and a receiving side radio terminal constituting a commercial radio network operating in a simplex mode, and a transmitting side radio terminal can select a receiving side radio terminal. And means for storing the adjusted value data of the adjusted voice level, wherein the receiving side wireless terminal adjusts the voice level according to the call signal level of the voice data transmitted from the transmitting side wireless terminal, Means for returning voice level adjustment value data at the moment when reception is interrupted to the transmitting side wireless terminal, and the transmitting side wireless terminal adjusts the microphone level according to the returned adjustment value data. And the receiving wireless terminal and the transmitting wireless terminal make a direct call.

本発明の無線端末は、業務用無線ネットワークの無線通話システムに使用される無線端末であって、前記受話側無線端末が、前記調整値データと前記送話側無線端末の接続番号のデータとを共に蓄積し、次回通話開始時には前記接続番号を照合し、自動的に前記調整値データを送信する手段を備えたことを特徴とする   A wireless terminal according to the present invention is a wireless terminal used in a wireless communication system for a commercial wireless network, wherein the receiving wireless terminal receives the adjustment value data and connection number data of the transmitting wireless terminal. A means is provided for accumulating together, collating the connection number at the start of the next call, and automatically transmitting the adjustment value data.

本発明の無線通話システムによれば、人や使用環境の変化に対応して、常時、きめ細かな音声レベルを調整できる無線通話システムが実現できる。   According to the wireless communication system of the present invention, it is possible to realize a wireless communication system that can always finely adjust the sound level in response to changes in people and usage environments.

本発明による、業務用無線ネットワークにおける無線通話システムの実施の形態について、図１を用いて説明する。図１は、本発明の無線通話システムの構成を示すブロック図である。業務用無線ネットワークは、１つまたは複数の基地局と複数の無線端末とから成り立つが、簡単のため、図１に基地局１と送話側無線端末２と受話側無線端末３とから構成される無線通話システムを示す。   An embodiment of a wireless call system in a business wireless network according to the present invention will be described with reference to FIG. FIG. 1 is a block diagram showing a configuration of a wireless communication system according to the present invention. The commercial wireless network is composed of one or a plurality of base stations and a plurality of wireless terminals. For simplicity, FIG. 1 includes a base station 1, a transmitting wireless terminal 2, and a receiving wireless terminal 3. Shows a wireless communication system.

基地局１は、送話側無線端末２から送られてきた音声データを受信し、送話側無線端末２が指定する受話側無線端末３に受信した音声データを送信する（ステップ１）。受話側無線端末３は、基地局１から送られてきた音声データを受信し（ステップ２）、受信した音声データのレベルに応じて音声レベルを調整する。受話側無線端末３は、この調整された音声レベルの調整値データを蓄積すると共に基地局１へ送信する（ステップ３）。通常のシンプレックスモードで動作する業務用無線ネットワークにおいて、この送信は、受信が途切れた瞬間に行われる。基地局１は、受話側無線端末３から送信された音声レベルの調整値データを受信し、送話側無線端末２へ送信する（ステップ４）。送話側無線端末２は基地局１から送信された音声レベルの調整値データを受信し、調整値データに従ってレベル調整回路のレベル値を調整する。送話側無線端末２は、レベル調整後の音声データを基地局１へ送信する（ステップ５）。基地局１は送話側無線端末２から送信されたれレベル調整後の音声データを受信し、受話側無線端末３へ送信する。受話側無線端末３は、送信されたレベル調整後の音声データを受信する（ステップ６）。   The base station 1 receives the voice data transmitted from the transmitter wireless terminal 2 and transmits the received voice data to the receiver wireless terminal 3 designated by the transmitter wireless terminal 2 (step 1). The receiver wireless terminal 3 receives the voice data transmitted from the base station 1 (step 2), and adjusts the voice level according to the level of the received voice data. The receiver radio terminal 3 accumulates the adjusted value data of the adjusted voice level and transmits it to the base station 1 (step 3). In a commercial wireless network operating in a normal simplex mode, this transmission is performed at the moment when reception is interrupted. The base station 1 receives the voice level adjustment value data transmitted from the receiver wireless terminal 3 and transmits it to the transmitter wireless terminal 2 (step 4). The transmitting radio terminal 2 receives the voice level adjustment value data transmitted from the base station 1 and adjusts the level value of the level adjustment circuit according to the adjustment value data. The transmitter radio terminal 2 transmits the level-adjusted voice data to the base station 1 (step 5). The base station 1 receives the voice data after the level adjustment transmitted from the transmitting wireless terminal 2 and transmits it to the receiving wireless terminal 3. The receiver wireless terminal 3 receives the transmitted voice data after level adjustment (step 6).

なお、以上説明した音声レベルの調整は、基地局を介さないで、無線端末同士で直接に行うことも可能である。また、調整された音声レベルの調整値データを送話側無線端末１の接続番号などのデータと共に蓄積しておくことにより、次回通話開始時には接続番号を照合し、自動的に蓄積されている調整値データを送ることも可能である。一般の携帯電話のような、フルデュプレックスモードの通話無線端末の場合は、受話中に受話音を聞きながらレベルを調整することができる。   It should be noted that the audio level adjustment described above can be directly performed between wireless terminals without using a base station. Further, by storing adjustment value data of the adjusted voice level together with data such as the connection number of the transmitting wireless terminal 1, the connection number is collated at the start of the next call and the adjustment stored automatically. It is also possible to send value data. In the case of a full-duplex mode telephone wireless terminal such as a general mobile phone, the level can be adjusted while listening to the reception sound during reception.

図２は、音声レベルの調整値データを送信する場合の、データの構成を示す説明図である。図２において、ＦＳには、送信データの同期を確定するための、フレーム同期信号が格納される。ＩＤには、送話側無線端末１が持つ認証情報が格納される。ＭＩＣには、音声レベルの調整値データが格納される。音声データには、通話時の音声データが格納される。受信側無線端末３は、音声レベルの調整値データをメモリに蓄積すると共に、ＭＩＣ領域に格納し、受信が途切れた瞬間に送話側無線端末１へ送信する。   FIG. 2 is an explanatory diagram showing a data configuration when audio level adjustment value data is transmitted. In FIG. 2, the FS stores a frame synchronization signal for determining the synchronization of transmission data. In the ID, authentication information possessed by the transmitting wireless terminal 1 is stored. Audio level adjustment value data is stored in the MIC. In the voice data, voice data at the time of a call is stored. The reception-side wireless terminal 3 accumulates the voice level adjustment value data in the memory, stores it in the MIC area, and transmits it to the transmission-side wireless terminal 1 at the moment when reception is interrupted.

図３は、送話側無線端末１が、受話側無線端末３から送信された図２に示すデータを受信して、音声レベル調整された音声データを送信するための回路構成を示すブロック図である。増幅器ＡＭＰ３１と制御回路ＣＰＵ３３は、レベル調整回路３２へ接続され、レベル調整回路３２はアナログ・デジタル変換回路ＡＤＣ３４へ接続されている。   FIG. 3 is a block diagram showing a circuit configuration for the transmitting wireless terminal 1 to receive the data shown in FIG. 2 transmitted from the receiving wireless terminal 3 and transmit the sound data whose sound level has been adjusted. is there. The amplifier AMP31 and the control circuit CPU33 are connected to a level adjustment circuit 32, and the level adjustment circuit 32 is connected to an analog / digital conversion circuit ADC34.

送話側無線端末１は、受話側無線端末３から送信された図２に示すデータの変調信号を受信し、復調する。復調された復調データはＣＰＵ３３へ入力される。ＣＰＵ３３は、復調データの中から図２に示すＭＩＣ部分のデータを抽出し、レベル調整回路３２へ出力する。レベル調整回路３２は、入力されたＭＩＣ部分のデータを基に、一般のデジタルアナログ変換器等を用いてレベル設定を行う。マイク（図示せず）から出力されたアナログ音声信号は、ＡＭＰ３１へ入力され、一定の増幅レベルに増幅された後、レベル調整回路３２へ出力される。レベル調整回路３２は、この入力されたアナログ音声信号を、設定されたレベルに再度増幅しＡＤＣ３４へ出力する。ＡＤＣ３４は、入力されたアナログ音声信号をアナログ・デジタル変換して、デジタル音声信号として出力する。   The transmitting wireless terminal 1 receives and demodulates the data modulation signal shown in FIG. 2 transmitted from the receiving wireless terminal 3. The demodulated demodulated data is input to the CPU 33. The CPU 33 extracts the data of the MIC part shown in FIG. 2 from the demodulated data and outputs it to the level adjustment circuit 32. The level adjustment circuit 32 performs level setting using a general digital-analog converter or the like based on the input MIC data. An analog audio signal output from a microphone (not shown) is input to the AMP 31, amplified to a constant amplification level, and then output to the level adjustment circuit 32. The level adjustment circuit 32 amplifies the input analog audio signal again to a set level and outputs it to the ADC 34. The ADC 34 performs analog-to-digital conversion on the input analog audio signal and outputs it as a digital audio signal.

図３に示される回路構成は、当該機能を実現する手段であれば、どのような回路または装置であってもよく、また機能の一部または全部をソフトウエアで実現することも可能である。さらに機能実現手段を、複数の回路によって実現してもよく、複数の機能を単一の回路で実現してもよい。   The circuit configuration shown in FIG. 3 may be any circuit or device as long as it realizes the function, and a part or all of the function can be realized by software. Furthermore, the function realizing means may be realized by a plurality of circuits, and a plurality of functions may be realized by a single circuit.
