特開２００７−５３５２７号公報JP 2007-53527 A

従来のＩＰ交換機は、会議通話用の呼制御信号および会議通話用回路を使用することなしに２者通話用の呼を確立していたため、既に２者通話が形成された状態に第３者が割り込む場合、一旦、当該２者通話呼を切断した後に、改めて会議通話用の呼制御信号と会議通話用回路を用いて、当該第３者をメンバとする会議通話呼を確立する必要があった。   Since the conventional IP exchange has established a call for a two-party call without using a call control signal for a conference call and a circuit for a conference call, the third party is in a state where a two-party call has already been formed. When interrupting, once the two-party call is disconnected, it is necessary to establish a conference call with the third party as a member by using a call control signal for the conference call and a circuit for the conference call. .

このため、最初に通話中であった２者は、会議通話が開催されるまでの間、通話を遮られるという問題があった。   For this reason, there was a problem that the two parties who were in the middle of the call were interrupted until the conference call was held.

本発明は上述の問題点に鑑み、既に確立された通話を遮断することなく容易に通話への割り込みを可能にするＩＰ交換機と、ＩＰ端末の提供を目的とする。   SUMMARY OF THE INVENTION In view of the above-described problems, an object of the present invention is to provide an IP exchange and an IP terminal that can easily interrupt a call without interrupting an already established call.

本発明のＩＰ交換機は、複数のＩＰ端末間の通話を制御するＩＰ交換機であって、各ＩＰ端末の送信パケットを取得するパケット交換部と、パケット交換部から送信パケットを取得し、同一通話にかかる送信パケットをＮ−１加算して各ＩＰ端末に送信する通話パケットを生成する会議通話生成部と、を備え、２者通話の際に、会議通話生成部が生成した通話パケットを通話対象のＩＰ端末に送信する。   An IP switch according to the present invention is an IP switch that controls a call between a plurality of IP terminals, a packet switching unit that acquires a transmission packet of each IP terminal, a transmission packet from the packet switching unit, and the same call A conference call generation unit that generates a call packet to be transmitted to each IP terminal by adding N-1 to the transmission packet, and the call packet generated by the conference call generation unit in a two-party call Send to IP terminal.

本発明のＩＰ交換機は、複数のＩＰ端末間の通話を制御するＩＰ交換機であって、各ＩＰ端末の送信パケットを取得するパケット交換部と、パケット交換部から送信パケットを取得し、同一通話にかかる送信パケットをＮ−１加算して各ＩＰ端末に送信する通話パケットを生成する会議通話生成部と、を備え、２者通話の際に、会議通話生成部が生成した通話パケットを通話対象のＩＰ端末に送信する。   An IP switch according to the present invention is an IP switch that controls a call between a plurality of IP terminals, a packet switching unit that acquires a transmission packet of each IP terminal, a transmission packet from the packet switching unit, and the same call A conference call generation unit that generates a call packet to be transmitted to each IP terminal by adding N-1 to the transmission packet, and the call packet generated by the conference call generation unit in a two-party call Send to IP terminal.

したがって、２者通話時に話者が通話を切断する操作をすることなく、通話への割り込みが可能になる。また、割り込む際の処理時間を短縮することができる。   Therefore, the call can be interrupted without the operation of the speaker disconnecting the call during a two-party call. Moreover, the processing time at the time of interruption can be shortened.

<A-1. Configuration>
FIG. 1 is a configuration diagram illustrating the IP exchange 100 according to the first embodiment, and illustrates a configuration related to a two-party call between the IP terminal A11 and the IP terminal B21.

ＩＰ交換機１００は、端末インタフェース（Ｉ／Ｆ）部Ａ１２、端末インタフェース（Ｉ／Ｆ）部Ｂ２２、呼制御信号処理部１、会議通話生成部２、及び音声パケット交換部３を備えている。端末Ｉ／Ｆ部Ａ１２は、ＩＰ端末Ａ１１と接続し、ＩＰ端末Ａ１１に対して音声データ及び呼制御信号の受渡しを行う。端末Ｉ／Ｆ部Ｂ２２は、ＩＰ端末Ｂ２１と接続し、ＩＰ端末Ｂ２１に対して音声データ及び呼制御信号の受渡しを行う。呼制御信号処理部１は、音声パケット交換部３、会議通話生成部２、端末Ｉ／Ｆ部Ａ１１，Ｂ２２と接続され、各部との間で呼制御信号を送受する。また、音声パケット交換部３も会議通話生成部２、端末Ｉ／Ｆ部Ａ１２，Ｂ２２と接続され、各部との間で音声データを送受する。   The IP exchange 100 includes a terminal interface (I / F) unit A12, a terminal interface (I / F) unit B22, a call control signal processing unit 1, a conference call generation unit 2, and a voice packet switching unit 3. The terminal I / F unit A12 is connected to the IP terminal A11 and delivers voice data and a call control signal to the IP terminal A11. The terminal I / F unit B22 is connected to the IP terminal B21 and delivers voice data and a call control signal to the IP terminal B21. The call control signal processing unit 1 is connected to the voice packet exchange unit 3, the conference call generation unit 2, and the terminal I / F units A11 and B22, and transmits / receives call control signals to / from each unit. The voice packet exchange unit 3 is also connected to the conference call generation unit 2 and the terminal I / F units A12 and B22, and transmits and receives voice data to and from each unit.

＜Ａ−２．動作＞
ＩＰ端末Ａ１１からＩＰ端末Ｂ２１に対して発信し、２者通話が行われる場合の動作を以下に説明する。ユーザがＩＰ端末Ａ１１から、オフフック（又は同等のキー操作）とＩＰ端末Ｂの個別番号を入力すると、ＩＰ端末Ａから端末Ｉ／Ｆ部Ａ１２を介して呼制御信号処理部１に発信信号が送信される。 <A-2. Operation>
The operation when a call is made from IP terminal A11 to IP terminal B21 and a two-party call is made will be described below. When the user inputs off-hook (or equivalent key operation) and the individual number of IP terminal B from IP terminal A11, a transmission signal is transmitted from IP terminal A to call control signal processing unit 1 via terminal I / F unit A12. Is done.

呼制御信号処理部１は発信信号を解析した後、ＩＰ端末Ｂに着信させるべく、呼制御信号処理部１と音声パケット交換部３、会議通話生成部２、端末Ｉ／Ｆ部Ｂ２２との間で当該呼制御信号を送受信する。   After the call control signal processing unit 1 analyzes the outgoing signal, the call control signal processing unit 1, the voice packet switching unit 3, the conference call generation unit 2, and the terminal I / F unit B22 are arranged to receive the incoming call to the IP terminal B. Then, the call control signal is transmitted / received.

その結果、ＩＰ端末Ａ１１の送話データが、端末Ｉ／Ｆ部Ａ１２、音声パケット交換部３を経て会議通話生成部２へ送信される。   As a result, the transmission data of the IP terminal A11 is transmitted to the conference call generation unit 2 via the terminal I / F unit A12 and the voice packet switching unit 3.

一方、端末Ｉ／Ｆ部Ｂ２２からＩＰ端末Ｂ２１へ着信信号が送信され、ＩＰ端末Ｂ２１において着信音が鳴動する。   On the other hand, an incoming signal is transmitted from the terminal I / F unit B22 to the IP terminal B21, and a ringing tone sounds in the IP terminal B21.

ここで、ＩＰ端末Ｂ２１のユーザが応答すると、ＩＰ端末Ｂからの応答信号が端末Ｉ／Ｆ部Ｂ２２を介して呼制御信号処理部１へ送信される。   Here, when the user of IP terminal B21 responds, a response signal from IP terminal B is transmitted to call control signal processing unit 1 via terminal I / F unit B22.

呼制御信号処理部１は応答信号を解析した後、音声パケット交換部３、会議通話生成部２、端末Ｉ／Ｆ部Ｂ２２との間で当該呼制御信号を送受信する。   After analyzing the response signal, the call control signal processing unit 1 transmits / receives the call control signal to / from the voice packet exchange unit 3, the conference call generation unit 2, and the terminal I / F unit B22.

その結果、ＩＰ端末Ｂ２１の送話データが、ＩＰ端末Ｂ２１から端末Ｉ／Ｆ部Ｂ２２、音声パケット交換部３を経て会議通話生成部２へ送信される。   As a result, the transmission data of the IP terminal B21 is transmitted from the IP terminal B21 to the conference call generation unit 2 via the terminal I / F unit B22 and the voice packet switching unit 3.

会議通話生成部２は、ＩＰ端末Ａ１１、Ｂ２２の送話データをＮ−１加算した会議通話データを生成する。なお、本明細書において「Ｎ−１加算」とは、全ての話者の音声（Ｎ）から、自分の音声を引き算することをいう。例えば、ＩＰ端末Ｂに送信する会議通話データは、ＩＰ端末Ａ１１，Ｂ２２の送話データの合成データからＩＰ端末Ｂ２２の送話データを引き算したものであり、ＩＰ端末Ａに送信する会議通話データは、ＩＰ端末Ａ１１，Ｂ２２の送話データの合成データからＩＰ端末Ａ１１の送話データを引き算したものである。これにより、ＩＰ端末Ａ１１，Ｂ２２では、自分の声以外の話者の合成音声を聞くことができる。   The conference call generation unit 2 generates conference call data obtained by adding N-1 to the transmission data of the IP terminals A11 and B22. In this specification, “N-1 addition” means subtracting one's own voice from the voices (N) of all speakers. For example, the conference call data transmitted to the IP terminal B is obtained by subtracting the transmission data of the IP terminal B22 from the synthesized data of the transmission data of the IP terminals A11 and B22, and the conference call data transmitted to the IP terminal A is , The transmission data of the IP terminal A11 is subtracted from the synthesized data of the transmission data of the IP terminals A11 and B22. As a result, the IP terminals A11 and B22 can hear the synthesized voice of the speaker other than their own voice.

そして、音声パケット交換部３、端末Ｉ／Ｆ部Ａ１２，Ｂ２２を介して会議通話データがＩＰ端末Ａ１１，Ｂ２１に送信され、ＩＰ端末Ａ１１，Ｂ２１間で２者通話が形成される。   Then, the conference call data is transmitted to the IP terminals A11 and B21 via the voice packet switching unit 3 and the terminal I / F units A12 and B22, and a two-party call is formed between the IP terminals A11 and B21.

図２は、３者通話時のＩＰ交換機を示す構成図である。この図では、図１で示したＩＰ端末Ａ１１，Ｂ２１の他に、ＩＰ端末Ｃ３１を示しており、ＩＰ端末Ｃ３１はＩＰ交換機１００の端末Ｉ／Ｆ部Ｃ３２に接続される。   FIG. 2 is a block diagram showing an IP exchange during a three-party call. In this figure, in addition to the IP terminals A11 and B21 shown in FIG. 1, an IP terminal C31 is shown, and the IP terminal C31 is connected to the terminal I / F unit C32 of the IP exchange 100.

図１で説明した２者通話にＩＰ端末Ｃ３１が割り込む場合の動作を、図２に沿って説明する。まず、ユーザがＩＰ端末Ｃ３１から割り込みを示す特番とＩＰ端末Ａ１１，Ｂ２１の個別番号を入力すると、ＩＰ端末Ｃ３１から割り込み参加要求信号が端末Ｉ／Ｆ部Ｃ３２を介して呼制御信号処理部１へ送信される。   The operation when the IP terminal C31 interrupts the two-party call described with reference to FIG. 1 will be described with reference to FIG. First, when the user inputs a special number indicating interruption from the IP terminal C31 and the individual numbers of the IP terminals A11 and B21, an interruption participation request signal is sent from the IP terminal C31 to the call control signal processing unit 1 via the terminal I / F unit C32. Sent.

呼制御信号処理部１は、割り込み参加要求信号を解析した後、音声パケット交換部３、会議通話生成部２、端末Ｉ／Ｆ部Ｃ２２との間で当該呼制御信号を送受信する。その結果、ＩＰ端末Ｃ３１の送話データは、ＩＰ端末Ｃ３１から端末Ｉ／Ｆ部Ｃ３２、音声パケット交換部３を経て会議通話生成部２へ送信される。   After analyzing the interrupt participation request signal, the call control signal processing unit 1 transmits / receives the call control signal to / from the voice packet exchange unit 3, the conference call generation unit 2, and the terminal I / F unit C22. As a result, the transmission data of the IP terminal C31 is transmitted from the IP terminal C31 to the conference call generation unit 2 via the terminal I / F unit C32 and the voice packet switching unit 3.

会議通話生成部２は、ＩＰ端末Ａ１１，Ｂ２１，Ｃ３１の送話データをＮ−１加算して会議通話データを生成する。会議通話データは、音声パケット交換部３、端末Ｉ／Ｆ部Ａ１２，Ｂ２２，Ｃ３２を介してＩＰ端末Ａ１１，Ｂ２１，Ｃ３１に送信され、こうしてＩＰ端末Ａ１１，Ｂ２１，Ｃ３１の３者会議通話が形成される。なお、さらに別のＩＰ端末が割り込んで４者以上の会議通話を形成する場合も、上記と同様の動作を行う。   The conference call generator 2 adds N-1 to the transmission data of the IP terminals A11, B21, C31 and generates conference call data. The conference call data is transmitted to the IP terminals A11, B21, and C31 via the voice packet switching unit 3 and the terminal I / F units A12, B22, and C32, thereby forming a three-party conference call of the IP terminals A11, B21, and C31. Is done. Even when another IP terminal interrupts and forms a conference call of four or more parties, the same operation as described above is performed.

＜Ａ−３．効果＞
実施の形態１のＩＰ交換機は、各ＩＰ端末の送信パケットを取得する音声パケット交換部３（パケット交換部）と、音声パケット交換部３から送信パケットを取得し、同一通話にかかる送信パケットをＮ−１加算して各ＩＰ端末に送信する通話パケットを生成する会議通話生成部２と、を備え、２者通話の際には、会議通話生成部２が生成した通話パケットを通話対象のＩＰ端末Ａ１１，Ｂ２１に送信する。従って、会議通話生成部２で通話パケットを生成する際に、新たなユーザからの送信パケットをＮ−１加算の対象に加えるだけで、新たなユーザの割り込みが可能となる。通話中のユーザが通話を切断する操作は不要である。 <A-3. Effect>
The IP switch according to the first embodiment acquires a transmission packet from the voice packet switching unit 3 (packet switching unit) that acquires the transmission packet of each IP terminal and the voice packet switching unit 3, and transmits the transmission packet for the same call to N And a conference call generation unit 2 that generates a call packet to be added to -1 and transmitted to each IP terminal, and in the case of a two-party call, the call packet generated by the conference call generation unit 2 is used as a call target IP terminal. Transmit to A11 and B21. Therefore, when the conference call generation unit 2 generates a call packet, a new user can be interrupted only by adding a transmission packet from the new user to the N-1 addition target. There is no need for the user in the call to disconnect the call.

＜Ｂ．実施の形態２＞
＜Ｂ−１．構成、動作＞
図３は、実施の形態２のＩＰ交換機１０１を示す構成図である。ここでは、ＩＰ端末Ａ１１，Ｂ２１，Ｃ３１の間の会議通話に関わる構成を示しており、図１に示す実施の形態１のＩＰ交換機１００と同一又は対応する構成には同一の参照符号を付している。 <B. Second Embodiment>
<B-1. Configuration, operation>
FIG. 3 is a configuration diagram illustrating the IP exchange 101 according to the second embodiment. Here, a configuration related to a conference call between IP terminals A11, B21, and C31 is shown, and the same reference numerals are assigned to the same or corresponding configurations as those in IP exchange 100 of the first embodiment shown in FIG. ing.

ＩＰ交換機１０１は、実施の形態１のＩＰ交換機１００の構成に、端末グループ記憶部４を追加したものである。これ以外の構成はＩＰ交換機１００と同様であり、以下、ＩＰ交換機１００と異なる点を中心に説明する。   IP switch 101 is obtained by adding terminal group storage unit 4 to the configuration of IP switch 100 of the first embodiment. The rest of the configuration is the same as that of the IP switch 100, and the following description will focus on differences from the IP switch 100.

端末グループ記憶部４には、会議通話を行うと想定されるグループメンバの情報（グループ番号とメンバ個別番号）が予め登録されている。２台のＩＰ端末Ａ１１，Ｂ２１間で２者通話を形成する際、呼制御信号処理部１は、着信側ＩＰ端末Ｂ２１から応答信号を受信すると、端末グループ記憶部４に登録されているデータを参照する。そして、同じ会議通話グループのなかで前記２者通話の話者以外のＩＰ端末に対してＩＰ端末Ｂ２１の応答信号を送信する。   In the terminal group storage unit 4, group member information (group number and member individual number) assumed to be used for a conference call is registered in advance. When the two-party call is formed between the two IP terminals A11 and B21, the call control signal processing unit 1 receives the response signal from the receiving side IP terminal B21, and stores the data registered in the terminal group storage unit 4 refer. Then, the response signal of the IP terminal B21 is transmitted to IP terminals other than the speaker of the two-party call in the same conference call group.

図４は、ＩＰ端末Ｃ３１の操作部を示している。図４に示すように、ＩＰ端末Ｃ３１は、操作部として、受話器３１１と、画面表示部３１２と、キー操作部３１３と、会議通話参加専用キー３１４を備えている。   FIG. 4 shows the operation unit of the IP terminal C31. As shown in FIG. 4, the IP terminal C31 includes a receiver 311, a screen display unit 312, a key operation unit 313, and a conference call participation dedicated key 314 as operation units.

端末グループ記憶部４において、ＩＰ端末Ａ１１，Ｂ２１，Ｃ３１が同じグループ（グループ番号１）に登録されているものとする。ＩＰ端末Ａ１１，Ｂ２１が２者通話の状態になると、ＩＰ端末Ｃ３１は着信側のＩＰ端末からの応答信号を受信する。そして、ＩＰ端末Ｃ３１の画面表示部３１２には、グループ番号１のグループの会議通話に参加可能な旨が表示される。言いかえれば、ＩＰ交換機１０１は、通話中のＩＰ端末Ａ１１，Ｂ２１が属するグループの非通話中のＩＰ端末Ｃ３１に対し、会議通話参加が可能な旨を通知する。ＩＰ端末Ｃ３１のユーザは、キー操作部３１３のキー押下又は会議通話参加専用キー３１４の押下を行って会議通話に参加する旨の指示を入力する。当該指示が入力されると、ＩＰ端末Ｃ３１の送話データは、ＩＰ端末Ｃ３１から端末Ｉ／Ｆ部Ｃ３２、音声パケット交換部３を経て会議通話生成部２に送信される。会議通話生成部２では、ＩＰ端末Ａ１１，Ｂ２１の送話データとＩＰ端末Ｃ３１の送話データをＮ−１加算処理して会議通話データを生成する。会議通話データは、会議通話生成部２から音声パケット交換部３、各端末Ｉ／Ｆ分Ａ１２，Ｂ２１，Ｃ３１を経てＩＰ端末Ａ１１，Ｂ２１，Ｃ３１に送信され、ＩＰ端末Ａ１１，Ｂ２１，Ｃ３１の３者会議通話が形成される。   It is assumed that IP terminals A11, B21, and C31 are registered in the same group (group number 1) in the terminal group storage unit 4. When the IP terminals A11 and B21 are in a two-party call state, the IP terminal C31 receives a response signal from the incoming IP terminal. The screen display unit 312 of the IP terminal C31 displays that it can participate in the conference call of the group with the group number 1. In other words, the IP exchange 101 notifies the non-calling IP terminal C31 of the group to which the talking IP terminals A11 and B21 belong that the conference call can be joined. The user of the IP terminal C31 inputs an instruction to participate in the conference call by pressing the key on the key operation unit 313 or the conference call participation dedicated key 314. When the instruction is input, the transmission data of the IP terminal C31 is transmitted from the IP terminal C31 to the conference call generation unit 2 via the terminal I / F unit C32 and the voice packet switching unit 3. In the conference call generation unit 2, N-1 addition processing is performed on the transmission data of the IP terminals A11 and B21 and the transmission data of the IP terminal C31 to generate conference call data. The conference call data is transmitted from the conference call generation unit 2 to the IP terminals A11, B21, and C31 via the voice packet switching unit 3 and the terminal I / F portions A12, B21, and C31, and the IP terminals A11, B21, and C31. Person conference call is formed.

The IP exchange 101 of the second embodiment further includes an IP terminal group storage unit 4 that stores the IP terminals A11, B21, and C31 for each group in addition to the configuration of the IP exchange 100 of the first embodiment. The IP terminal C31 in the group to which the IP terminals A11 and B21 belong is notified that the conference call can be joined.

また、実施の形態２のＩＰ交換機１０１により通話を制御されるＩＰ端末Ｃ３１は、ＩＰ交換機１０１から会議通話参加が可能な旨の通知を受けると、画面表示部３１２に当該通知内容を表示する。よって、ユーザは、同一グループの他のＩＰ端末間で会議通話が開始されたことを知ることができ、適宜当該会議通話に参加することができる。   In addition, upon receiving a notification that the conference call participation is possible from the IP exchange 101, the IP terminal C31 whose call is controlled by the IP exchange 101 of the second embodiment displays the notification content on the screen display unit 312. Therefore, the user can know that the conference call has started between other IP terminals in the same group, and can appropriately participate in the conference call.

なお、本発明は、その発明の範囲内において、各実施の形態を自由に組み合わせたり、各実施の形態を適宜、変形、省略することが可能である。   It should be noted that the present invention can be freely combined with each other within the scope of the invention, and each embodiment can be appropriately modified or omitted.
