Description

本発明は、無線通信機に関し、例えば、プレストーク通信などの単信通信を行う無線通信機における通話音声録音機能に関するものである。   The present invention relates to a wireless communication device, for example, a call voice recording function in a wireless communication device that performs simplex communication such as press talk communication.

近年、地域防災における防災情報伝達の重要性がクローズアップされ、これに応じて、例えば（社）電波産業会（ＡＲＩＢ）では、標準規格ARIB STD-T79として、双方向通信を行う複信通信を用いた市町村デジタル移動通信システムと題する規格について策定している。他方、防災情報伝達用の携帯無線機としては、プレストーク通信などの単信通信を行う無線通信機も存在する。   In recent years, the importance of disaster prevention information transmission in regional disaster prevention has been highlighted, and in response to this, the Radio Industry Association (ARIB), for example, has established duplex communications for two-way communication as standard ARIB STD-T79. A standard titled Municipal Digital Mobile Communication System used is being developed. On the other hand, there are wireless communication devices that perform simplex communication such as press talk communication as portable wireless devices for transmitting disaster prevention information.

このような防災情報伝達用の携帯無線機において、該携帯無線機の携帯者が呼出に応じられない場合、呼出相手からの通話音声を録音する、いわゆる伝言メモ機能が備えられている。複信通信の場合は、呼出相手からの着信に対して自動応答を行い、応答メッセージと録音開始音を呼出相手に送信した後、録音開始するようにしている。しかし、単信通信の場合は、応答メッセージや録音開始音を呼出相手に送信することはできず、呼出相手が通話してくるタイミング、すなわち録音開始するタイミングをつかむことが困難である。   In such a portable radio for transmitting disaster prevention information, a so-called message memo function is provided for recording a call voice from a call partner when a portable user of the portable radio cannot respond to the call. In duplex communication, an automatic response is made to an incoming call from the calling party, and after a response message and a recording start sound are transmitted to the calling party, recording is started. However, in simplex communication, a response message and recording start sound cannot be transmitted to the calling party, and it is difficult to grasp the timing when the calling party makes a call, that is, the recording start timing.

下記の特許文献１には、パーソナル無線機が、相手側の無線機からの制御信号によって、自動的に通話チャネルに切換り、交信内容を自動的に録音して、一定時間後に録音動作を停止する技術が記載されている。   In the following Patent Document 1, a personal wireless device automatically switches to a call channel in response to a control signal from a counterpart wireless device, automatically records the communication contents, and stops the recording operation after a certain time. The technology to do is described.

以下、本発明の実施形態について図を用いて説明する。
まず、本発明の実施形態に係る無線通信機の構成について、図１を用いて説明する。図１は、本発明の実施形態に係る無線通信機の構成を示す図である。この無線通信機は、例えば、プレストーク方式の車載無線機あるいは携帯無線機である。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
First, the configuration of a wireless communication device according to an embodiment of the present invention will be described with reference to FIG. FIG. 1 is a diagram illustrating a configuration of a wireless communication device according to an embodiment of the present invention. This wireless communication device is, for example, a press talk type on-vehicle wireless device or a portable wireless device.

図１に示すように、本実施形態に係る無線通信機は、他の無線通信機との送受信を行うためのアンテナ１３、送受信を切替えるための切換スイッチ１４、他の無線通信機からの通話内容を含む信号を受信する受信部１５、他の無線通信機に対し通話内容を含む信号を送信する送信部１６、他の無線通信機からの通話内容等を音声出力するスピーカ１７、操作者からの入力操作を受付ける操作部１８、受信部１５で受信した通話内容を録音する録音部２１、録音部２１における録音時間等を計測する計測部１９、操作者からの音声入力を受付けるマイク２０、制御部１１、記憶部１２を備える。操作部１８は、各種情報を表示する表示部を備えるものであってもよい。   As shown in FIG. 1, the wireless communication device according to the present embodiment includes an antenna 13 for performing transmission / reception with another wireless communication device, a changeover switch 14 for switching transmission / reception, and the contents of a call from the other wireless communication device. Receiving unit 15 for receiving a signal including a signal, a transmitting unit 16 for transmitting a signal including a call content to another wireless communication device, a speaker 17 for outputting a call content from another wireless communication device, and the like from an operator An operation unit 18 that accepts input operations, a recording unit 21 that records the content of a call received by the receiving unit 15, a measurement unit 19 that measures recording time in the recording unit 21, a microphone 20 that accepts voice input from an operator, a control unit 11 and a storage unit 12 are provided. The operation unit 18 may include a display unit that displays various types of information.

制御部１１は、ＣＰＵ（Central Processing Unit）を備え、受信部１５、送信部１６、操作部１８、録音部２１、計測部１９など、無線通信機を構成する各構成部を制御する。
制御部１１は、呼出側の無線通信機からの信号を一方的に受信する単信通信状態において、受信部１５で受信した受信信号がアイドル状態からビジー状態になると、つまり、受信した信号が自分宛であることを認識し回線接続すると、録音部２１の録音動作を開始して受信部１５で受信した受信信号を録音部２１に録音するとともに、計測部１９の録音時間計測動作又は録音データ量計測動作を開始し、該計測した録音時間又は録音データ量が録音可能な最大値である所定の第１の値に達したとき、あるいは、受信部１５で受信した受信信号がビジー状態からアイドル状態になったときに、録音部２１の録音動作を停止する。
また、制御部１１は、録音部２１の録音動作を停止した後、録音部２１の録音時間又は録音データ量が所定の第２の値よりも小さい場合に、録音部２１に録音した録音内容を破棄するものである。 The control unit 11 includes a CPU (Central Processing Unit), and controls each component configuring the wireless communication device such as the reception unit 15, the transmission unit 16, the operation unit 18, the recording unit 21, and the measurement unit 19.
In the simplex communication state in which the signal from the calling side wireless communication device is unilaterally received, the control unit 11 changes the received signal received by the receiving unit 15 from the idle state to the busy state. When the address is recognized and connected to the line, the recording operation of the recording unit 21 is started and the received signal received by the receiving unit 15 is recorded in the recording unit 21 and the recording time measuring operation or recording data amount of the measuring unit 19 is recorded. When the measurement operation is started and the measured recording time or recording data amount reaches a predetermined first value which is the maximum value that can be recorded, or the reception signal received by the receiving unit 15 is changed from the busy state to the idle state. When it becomes, the recording operation of the recording unit 21 is stopped.
In addition, after the recording operation of the recording unit 21 is stopped, the control unit 11 determines the recording content recorded in the recording unit 21 when the recording time or the recording data amount of the recording unit 21 is smaller than a predetermined second value. Discard it.

ここで、ビジー状態とは、単信通信状態で使用する周波数において、一定レベル以上の受信信号が存在し、受信部１５で検出される状態であり、アイドル状態とは、一定レベル以上の受信信号が存在せず、受信部１５で検出されない状態である。したがって、制御部１１は、呼出側の無線通信機からの通話信号が送信中の状態をビジー状態と判断し、呼出側の無線通信機からの通話信号が切断中の状態をアイドル状態と判断する。   Here, the busy state is a state in which a reception signal of a certain level or higher exists in the frequency used in the simplex communication state and is detected by the receiving unit 15, and the idle state is a reception signal of a certain level or more. Does not exist and is not detected by the receiving unit 15. Therefore, the control unit 11 determines that the call signal from the caller's wireless communication device is being transmitted as busy, and determines that the call signal from the caller's wireless communication device is disconnected as the idle state. .

また、単信通信状態において、呼出側が通信を切断し、呼出側の無線通信機からの通話信号が切断された直後に、切断時に発生するノイズのため、短時間、例えば１〜２秒間程度ビジー状態となり、その後、アイドル状態となる。したがって、制御部１１は、呼出側の無線通信機からの通話信号が切断された直後に録音した録音内容を破棄する、すなわち、録音時間又は録音データ量が所定の第２の値、例えば３秒間よりも小さい場合に、録音部２１に録音した録音内容を破棄するようにしている。   Also, in a simplex communication state, immediately after the caller disconnects communication and the call signal from the caller's wireless communication device is disconnected, the noise generated at the time of disconnection is short, for example, about 1-2 seconds busy. State, and then the idle state. Therefore, the control unit 11 discards the recorded content immediately after the call signal from the calling wireless communication device is disconnected, that is, the recording time or the recorded data amount is a predetermined second value, for example, 3 seconds. If it is smaller, the recorded content recorded in the recording unit 21 is discarded.

録音部２１は、制御部１１の制御に従い、受信部１５で受信した通話内容の受信信号を、録音部２１内のメモリに記憶する。このメモリは、例えば磁気テープやディスクや半導体メモリ等で構成することができる。あるいは、録音部２１は、通話内容を記憶部１２に記憶するようにすることも可能である。
計測部１９は、録音部２１における録音時間、又は録音部２１における録音データ量を計測するものである。 The recording unit 21 stores the reception signal of the call content received by the receiving unit 15 in a memory in the recording unit 21 under the control of the control unit 11. This memory can be composed of, for example, a magnetic tape, a disk, a semiconductor memory, or the like. Alternatively, the recording unit 21 can store the call contents in the storage unit 12.
The measuring unit 19 measures a recording time in the recording unit 21 or a recording data amount in the recording unit 21.

記憶部１２は、制御部１１の動作プログラム等を格納している。また、記憶部１２は、上述した第１の値と第２の値を格納している。第１の値は、計測部１９で計測した録音時間又は録音データ量が、この第１の値に達したときに、録音部２１の録音動作を停止するものである。第２の値は、録音部２１の録音動作を停止した後、録音部２１の録音時間又は録音データ量が、この第２の値よりも小さい場合に、録音部２１に録音した録音内容を破棄するものである。   The storage unit 12 stores an operation program of the control unit 11 and the like. The storage unit 12 stores the first value and the second value described above. The first value is to stop the recording operation of the recording unit 21 when the recording time or the recording data amount measured by the measuring unit 19 reaches the first value. The second value is that after the recording operation of the recording unit 21 is stopped, the recording content recorded in the recording unit 21 is discarded when the recording time or the recording data amount of the recording unit 21 is smaller than the second value. To do.

この無線通信機の通話動作を説明する。先ず、操作部１８を操作し、例えば、テンキーで相手側の無線通信機の番号を入力し、通話ボタンを押す。上位装置より送信権が付与されれば送信状態となるので、マイク２０から入力された通話の音声信号は、制御部１１で所定の信号処理がなされた後、送信部６２に入力される。送信部６２に入力された信号は、送信のための所定の変調がなされ、所定の送信周波数に変換され、切換スイッチ１４を介してアンテナ１３から出力され、相手側の無線通信機へ送信される。   The call operation of this wireless communication device will be described. First, the operation unit 18 is operated, for example, the number of the partner wireless communication device is input using the numeric keypad, and the call button is pressed. When the transmission right is given from the host device, the transmission state is set. Therefore, the voice signal of the call input from the microphone 20 is input to the transmission unit 62 after predetermined signal processing is performed by the control unit 11. The signal input to the transmitter 62 is subjected to predetermined modulation for transmission, converted into a predetermined transmission frequency, output from the antenna 13 via the changeover switch 14, and transmitted to the counterpart wireless communication device. .

一方、相手側の無線通信機からの通話の送信信号は、アンテナ１３で受信され、切換スイッチ１４を介して受信部１５に入力される。受信部１５に入力された信号は、高周波増幅され、所定の中間周波数に変換され復調されて制御部１１に供給され、制御部１１で所定の信号処理がなされる。その後、スピーカ１７から音声信号として出力される。   On the other hand, a transmission signal of a call from the counterpart wireless communication device is received by the antenna 13 and input to the receiving unit 15 via the changeover switch 14. The signal input to the receiving unit 15 is amplified at a high frequency, converted to a predetermined intermediate frequency, demodulated, supplied to the control unit 11, and the control unit 11 performs predetermined signal processing. Thereafter, it is output as an audio signal from the speaker 17.

ここで、無線通信機の録音機能がＯＮになっている場合には、制御部１１は、受信部１５で受信した受信信号がアイドル状態からビジー状態になると録音部２１の録音動作を開始して受信部１５で受信した受信信号を録音部２１に録音するとともに、計測部１９の録音時間計測動作又は録音データ量計測動作を開始し、該計測した録音時間又は録音データ量が所定の第１の値に達したとき、あるいは、受信部１５で受信した受信信号がビジー状態からアイドル状態になったときに、録音部２１の録音動作を停止する。
また、制御部１１は、録音部２１の録音動作を停止した後、録音部２１の録音時間又は録音データ量が所定の第２の値よりも小さい場合に、録音部２１に録音した録音内容を破棄する。 Here, when the recording function of the wireless communication device is ON, the control unit 11 starts the recording operation of the recording unit 21 when the reception signal received by the receiving unit 15 changes from the idle state to the busy state. The reception signal received by the receiving unit 15 is recorded in the recording unit 21 and the recording time measuring operation or the recording data amount measuring operation of the measuring unit 19 is started. The measured recording time or recording data amount is a predetermined first value. When the value reaches the value or when the reception signal received by the receiving unit 15 changes from the busy state to the idle state, the recording operation of the recording unit 21 is stopped.
In addition, after the recording operation of the recording unit 21 is stopped, the control unit 11 determines the recording content recorded in the recording unit 21 when the recording time or the recording data amount of the recording unit 21 is smaller than a predetermined second value. Discard.

次に、本実施形態に係る無線通信機の録音動作について、図２を用いて説明する。図２は、本発明の実施形態に係る無線通信機の録音動作を示す図である。
まず、無線通信機の制御部１１は、受信部１５で受信した受信信号がビジー状態か否か、つまり、他の無線通信機との間の無線区間がビジー状態かアイドル状態かを判断し（ステップＳ１）、ビジー状態になるまで待機する（ステップＳ１でＮｏ）。 Next, the recording operation of the wireless communication device according to the present embodiment will be described with reference to FIG. FIG. 2 is a diagram illustrating a recording operation of the wireless communication device according to the embodiment of the present invention.
First, the control unit 11 of the wireless communication device determines whether or not the reception signal received by the reception unit 15 is busy, that is, whether the wireless section with another wireless communication device is busy or idle ( Step S1), and waits until a busy state is reached (No in step S1).

ビジー状態になると（ステップＳ１でＹｅｓ）、録音部２１又は記憶部１２内のＲＡＭ上の音声データファイルを開き（ステップＳ２）、該音声データファイルに、相手の無線通信機からの通話音声データの書き込みを開始、つまり録音を開始する（ステップＳ３）。   When the busy state is reached (Yes in step S1), the voice data file on the RAM in the recording unit 21 or the storage unit 12 is opened (step S2), and the voice data from the partner wireless communication device is stored in the voice data file. Writing is started, that is, recording is started (step S3).

録音中において、他の無線通信機との間の無線区間がビジー状態かアイドル状態かを判断し（ステップＳ４）、アイドル状態を検出した場合は（ステップＳ４でＮｏ）、ステップＳ６へ移行する。ビジー状態を検出した場合は（ステップＳ４でＹｅｓ）、録音したデータサイズが所定の第１の値（Ｍａｘ値）に達したか否かを判断し（ステップＳ５）、所定の第１の値に達していない場合は（ステップＳ５でＮｏ）、ステップＳ３へ戻り録音を続行する。この所定の第１の値は、録音最大時間であり、例えば３０秒間である。   During recording, it is determined whether the wireless section with another wireless communication device is busy or idle (step S4). If an idle state is detected (No in step S4), the process proceeds to step S6. If a busy state is detected (Yes in step S4), it is determined whether the recorded data size has reached a predetermined first value (Max value) (step S5), and the predetermined first value is reached. If not reached (No in step S5), the process returns to step S3 to continue recording. The predetermined first value is a maximum recording time, for example, 30 seconds.

録音したデータサイズが所定の第１の値に達した場合は（ステップＳ５でＹｅｓ）、ステップＳ６へ移行し、録音を停止して音声データファイルを閉じる。
録音を停止した後に、録音したデータサイズが所定の第２の値（Ｍｉｎ値）よりも小さいか否かを判断し（ステップＳ７）、所定の第２の値よりも小さい場合は（ステップＳ７でＮｏ）、録音した音声データファイルを削除して（ステップＳ９）、処理を終了する。録音したデータサイズが所定の第２の値以上であった場合は（ステップＳ７でＹｅｓ）、録音した音声データファイルを記憶部１２内のフラッシュＲＯＭに保存し（ステップＳ８）、処理を終了する。この所定の第２の値は、例えば３秒間である。 When the recorded data size reaches the predetermined first value (Yes in step S5), the process proceeds to step S6, recording is stopped, and the audio data file is closed.
After the recording is stopped, it is determined whether or not the recorded data size is smaller than a predetermined second value (Min value) (step S7). If the recorded data size is smaller than the predetermined second value (in step S7). No), the recorded voice data file is deleted (step S9), and the process is terminated. If the recorded data size is greater than or equal to the predetermined second value (Yes in step S7), the recorded audio data file is stored in the flash ROM in the storage unit 12 (step S8), and the process is terminated. This predetermined second value is, for example, 3 seconds.

以上説明した実施形態によれば、単信通信状態の無線通信機において、適切なタイミングで録音することができ、また、無駄な録音データを保存することがないのでメモリを有効的に利用できる。   According to the embodiment described above, in a wireless communication apparatus in a simplex communication state, recording can be performed at an appropriate timing, and useless recording data is not saved, so that the memory can be used effectively.
