Description

通信端末及びデータ記録方法Communication terminal and data recording method
　本発明は、クライアントに発言権を付与するサーバとの間で通信を行う通信端末に関し、特に、ＰｏＣ（Ｐｕｓｈ－ｔｏ－Ｔａｌｋ　ｏｖｅｒ　Ｃｅｌｌｕｌａｒ）サーバとの間で通信を行う通信端末、及びその通信端末によるデータ記録方法に関する。 The present invention relates to a communication terminal that communicates with a server that gives a client the right to speak, and in particular, a communication terminal that communicates with a PoC (Push-to-Talk over Cellular) server, and the communication terminal The present invention relates to a data recording method.
　近年利用されている携帯電話の中には、ＰｏＣを利用した通信機能を備えるものがある。ＰｏＣを利用した通信を実施するために、サーバがクライアントに付与する発言権の管理を行い（以後、クライアントに付与する発言権の管理を行うサーバのことをＰｏＣサーバ、発言権を付与されるクライアントのことをＰｏＣクライアントと称することがある。）、他方、ＰｏＣサーバから発言権を付与されたＰｏＣクライアントはＰｏＣサーバに各種データを送信し、ＰｏＣサーバから発言権を付与されなかったＰｏＣクライアントは発言権を付与されたＰｏＣクライアントから送信された各種データをＰｏＣサーバから受信する。 Some mobile phones used in recent years have a communication function using PoC. In order to perform communication using PoC, the server manages the right to speak given to the client (hereinafter, the server that manages the right to speak given to the client is the PoC server, and the client to which the right is given. On the other hand, a PoC client that has been granted the right to speak from the PoC server sends various data to the PoC server, and a PoC client that has not been granted the right to speak from the PoC server. Various data transmitted from the PoC client to which the right is granted are received from the PoC server.
　特許文献１には、ＰｏＣクライアントとＰｏＣサーバとによって構成され、ＰｏＣサーバが判定ルール（セッションの通信内容の記録が必要かどうか判定するための条件）に基づいてＰｏＣクライアントから受信したデータを記録するか否かを判定するＰｏＣシステムについて開示されている。
特開２００５－２３４６６６号公報 Patent Document 1 includes a PoC client and a PoC server, and the PoC server records data received from the PoC client based on a determination rule (a condition for determining whether recording of communication contents of a session is necessary). A PoC system for determining whether or not is disclosed.
JP 2005-234666 A
　しかしながら、特許文献１に開示されているＰｏＣシステムは、通信内容の記録が必要と判定されればその通信内容を記録するものであり、追って再生するときの利用者による利便性を踏まえて通信内容を記録する点については考慮していない。ＰｏＣシステムは、ＰｏＣサーバを介して、セッションを確立した複数台のＰｏＣクライアント間でデータの送受信を行うものであり、ＰｏＣサーバが各ＰｏＣクライアントから受信したデータを記録したとしても、そのＰｏＣクライアントの台数が増える程、記録しておいたデータを再生するときにどのデータがどのＰｏＣクライアントによって送信されたたものかを特定することが困難になる。 However, the PoC system disclosed in Patent Document 1 records the communication content if it is determined that the recording of the communication content is necessary, and the communication content is based on convenience for the user when playing back later. The point of recording is not considered. The PoC system transmits and receives data between a plurality of PoC clients that have established a session via the PoC server. Even if the PoC server records data received from each PoC client, the PoC client records the data of the PoC client. As the number increases, it becomes more difficult to specify which data is transmitted by which PoC client when the recorded data is reproduced.
　また、特許文献１には、ＰｏＣサーバがＰｏＣクライアントから受信したデータを記録するＰｏＣシステムを中心に開示されているが、ＰｏＣクライアントがＰｏＣサーバへ送信するデータまたはＰｏＣサーバから受信したデータを記録する構成も考えられる。この構成では、ＰｏＣクライアントは、ＰｏＣサーバから受信するデータだけでなく、ＰｏＣサーバへ送信するデータを記録する処理についても考える必要がある。 Patent Document 1 discloses a PoC system that records data received from a PoC client by a PoC server, but records data transmitted by a PoC client to a PoC server or data received from a PoC server. Configuration is also conceivable. In this configuration, the PoC client needs to consider not only data received from the PoC server but also processing for recording data to be transmitted to the PoC server.
　本発明は、上記事情に鑑みてなされたもので、ＰｏＣサーバへ送信するデータまたはＰｏＣサーバから受信したデータを記録するＰｏＣクライアントであって、その記録しておいたデータを再生するときの利用者の利便性を向上させることができる通信端末及びデータ記録方法を提供することを目的とする。 The present invention has been made in view of the above circumstances, and is a PoC client that records data transmitted to a PoC server or data received from a PoC server, and a user who reproduces the recorded data. An object of the present invention is to provide a communication terminal and a data recording method that can improve convenience.

　以下、本発明の実施の形態の通信端末について、図１に示す、本発明の実施の形態の通信端末の機能ブロック図と、図２に示す、本発明の実施の形態の通信端末及びサーバにより構成される通信システムの構成図と、を参照して、詳細に説明する。 Hereinafter, with respect to the communication terminal according to the embodiment of the present invention, the functional block diagram of the communication terminal according to the embodiment of the present invention shown in FIG. 1 and the communication terminal and server according to the embodiment of the present invention shown in FIG. The configuration will be described in detail with reference to the configuration diagram of the configured communication system.
　本発明の実施の形態の通信端末は、通信インタフェース部１０１、ＰｏＣセッション制御部１０２、セッション情報取得部１０３、受信内容データ制御部１０４、入力内容データ制御部１０５、入力インタフェース部１０６、音声入力部１０７、操作部１０８、通信内容データ記録制御部１０９、記録部１１０、記録データ再生制御部１１１、出力インタフェース部１１２、音声出力部１１３、表示部１１４、を含んで構成される。 The communication terminal according to the embodiment of the present invention includes a communication interface unit 101, a PoC session control unit 102, a session information acquisition unit 103, a received content data control unit 104, an input content data control unit 105, an input interface unit 106, and a voice input unit. 107, an operation unit 108, a communication content data recording control unit 109, a recording unit 110, a recorded data reproduction control unit 111, an output interface unit 112, an audio output unit 113, and a display unit 114.
　通信インタフェース部１０１は、サーバ２との間での通信を実現するためのデバイスにより構成される。通信インタフェース１０１は、サーバ２から受信したＳＩＰ（Ｓｅｓｓｉｏｎ　Ｉｎｉｔｉａｌ　Ｐｒｏｔｏｃｏｌ）メッセージやフロア権メッセージ（発言権を付与または解放した発言者に関する情報を含む）をＰｏＣセッション制御部１０２に出力し、ＰｏＣセッション制御部１０２から入力したＳＩＰメッセージやフロア権メッセージをサーバ２に送信する。また、通信インタフェース１０１は、サーバ２から受信したプレゼンス情報（プレゼンス情報は、ＳＩＰに従って、サーバ－クライアント間で送受信される。）をＰｏＣセッション制御部１０２に出力し、自機（通信端末）のステータスをプレンゼンス情報としてサーバ２に送信する。また、通信インタフェース１０１は、サーバを介して他のクライアントとの間で確立したセッションを利用してサーバ２から受信したコンテンツ（コンテンツは、オーディオデータ、ビデオデータ、テキストデータなどのメディアデータにより構成される。）を受信内容データ制御部１０４に出力する。また、通信インタフェース１０１は、サーバを介して他のクライアントとの間で確立したセッションを利用して入力内容データ制御部１０５から入力したコンテンツをサーバ２に送信する。 The communication interface unit 101 is configured by a device for realizing communication with the server 2. The communication interface 101 outputs the SIP (Session Initial Protocol) message and the floor right message (including information on the speaker who has given or released the right to speak) received from the server 2 to the PoC session control unit 102, and the PoC session control unit The SIP message and floor right message input from 102 are transmitted to the server 2. Further, the communication interface 101 outputs the presence information received from the server 2 (the presence information is transmitted and received between the server and the client in accordance with SIP) to the PoC session control unit 102, and the status of the own device (communication terminal). Is transmitted to the server 2 as presence information. The communication interface 101 is content received from the server 2 using a session established with another client via the server (the content is composed of media data such as audio data, video data, and text data). Is output to the received content data control unit 104. Further, the communication interface 101 transmits the content input from the input content data control unit 105 to the server 2 using a session established with another client via the server.
　ＰｏＣセッション制御部１０２は、ＳＩＰに従って、通信インタフェース１０２からＳＩＰメッセージやフロア権メッセージ、またはプレゼンス情報を入力し、生成したＳＩＰメッセージやフロア権メッセージ、または自機（通信端末）のプレンゼンス情報を通信インタフェース１０２に出力することによって、ＰｏＣによる通信を制御する。 The PoC session control unit 102 inputs a SIP message, floor right message, or presence information from the communication interface 102 in accordance with SIP, and transmits the generated SIP message, floor right message, or presence information of the own device (communication terminal) to the communication interface. By outputting to 102, communication by PoC is controlled.
　セッション情報取得部１０３は、ＰｏＣセッション制御部１０２によって制御されているメッセージの中から、任意のメッセージを抽出するフィルタ機能を備える。セッション情報取得部１０３は、特に、ＰｏＣセッション制御部１０２によって制御されているメッセージの中にフロア権メッセージがあった場合、そのフロア権メッセージを抽出し、フロア権メッセージに含まれる、サーバが発言権を付与した発言者（クライアント）を識別する識別情報を取得する。例えば、図２では、通信端末１ａに発言権１２ａが付与されているが、通信端末１ａは発言権が付与されたクライアントとして自機（通信端末１ａ）の識別情報を取得し、通信端末１ｂ、１ｃ、１ｄは発言権が付与されたクライアントとして他機（通信端末１ａ）の識別情報を取得する。また、セッション情報取得部１０３は、ＰｏＣセッション制御部１０２によって制御されているメッセージの中にプレゼンス情報があった場合、そのプレゼンス情報を抽出し、プレゼンス情報に含まれる、各クライアントのステータスを取得する。例えば、図２では、通信端末１ａは、他機（通信端末１ｂ、１ｃ、１ｄ）のステータスとして、通信端末１ｂ、１ｄからはＰｏＣを利用したコミュニケーションに参加していることを表すステータス「参加」１１ｂ、１１ｄを、通信端末１ｃからはＰｏＣを利用したコミュニケーションに参加していないことを表すステータス「不参加」１１ｃを、それぞれ取得する。 The session information acquisition unit 103 has a filter function for extracting an arbitrary message from the messages controlled by the PoC session control unit 102. In particular, when there is a floor right message in the message controlled by the PoC session control unit 102, the session information acquisition unit 103 extracts the floor right message, and the server included in the floor right message The identification information for identifying the speaker (client) to which is assigned. For example, in FIG. 2, the right to speak 12a is given to the communication terminal 1a, but the communication terminal 1a acquires the identification information of its own device (communication terminal 1a) as a client to which the right to speak is given, and the communication terminal 1b, 1c and 1d acquire the identification information of the other device (communication terminal 1a) as a client to which the right to speak is granted. In addition, when there is presence information in the message controlled by the PoC session control unit 102, the session information acquisition unit 103 extracts the presence information and acquires the status of each client included in the presence information. . For example, in FIG. 2, the status “participation” indicating that the communication terminal 1 a participates in communication using PoC from the communication terminals 1 b and 1 d as the status of the other devices ( communication terminals 1 b, 1 c, and 1 d). 11b and 11d are respectively acquired from the communication terminal 1c as status “non-participation” 11c indicating that the communication terminal 1c does not participate in communication using PoC.
　受信内容データ制御部１０４は、サーバを介して他のクライアントとの間でセッションが確立した後に通信インタフェース１０１から入力したコンテンツを復号し、通信内容データ記録制御部１０９に出力する。例えば、図２のように、通信端末１ａに発言権が付与されている場合、通信端末１ｂ、１ｃ、１ｄの受信内容データ制御部１０４は、サーバ２を介して通信端末１ａとの間でセッションが確立した後、通信端末１ａからサーバ２を介して受信したコンテンツを通信内容データ記録制御部１０９に出力する。 The received content data control unit 104 decrypts the content input from the communication interface 101 after a session is established with another client via the server, and outputs the decrypted content to the communication content data recording control unit 109. For example, as shown in FIG. 2, when the communication terminal 1 a is granted the right to speak, the received content data control unit 104 of the communication terminals 1 b, 1 c, 1 d performs a session with the communication terminal 1 a via the server 2. Is established, the content received from the communication terminal 1a via the server 2 is output to the communication content data recording control unit 109.
　入力内容データ制御部１０５は、利用者からの音声入力を受け付ける音声入力部１０７や利用者による操作を受け付ける操作部１０８などのデバイスに接続された入力インタフェース部１０６を介して、オーディオデータ、ビデオデータ、テキストデータ等のメディアデータを入力すると、通信インタフェース１０１及び通信内容データ記録制御部１０９に出力する。例えば、図２のように、通信端末１ａに発言権が付与されている場合、通信端末１ａの入力内容データ制御部１０５は、サーバ２を介して他の通信端末１ｂ、１ｃ、１ｄとの間でセッションが確立した後、入力インタフェース部１０６を介して入力したメディアデータを通信内容データ記録制御部１０９に出力する。 The input content data control unit 105 receives audio data and video data via an input interface unit 106 connected to a device such as a voice input unit 107 that receives a voice input from a user and an operation unit 108 that receives a user operation. When media data such as text data is input, it is output to the communication interface 101 and the communication content data recording control unit 109. For example, as shown in FIG. 2, when the communication terminal 1 a is granted the right to speak, the input content data control unit 105 of the communication terminal 1 a communicates with the other communication terminals 1 b, 1 c, 1 d via the server 2. After the session is established, the media data input via the input interface unit 106 is output to the communication content data recording control unit 109.
　通信内容データ記録制御部１０９は、入力インタフェース部１０６を介して操作部１０８による記録開始操作を受け付けると、受信内容データ制御部１０４または入力内容データ制御部１０５から入力したコンテンツを記録部１１０に記録する。記録する際、通信内容データ記録制御部１０９は、セッション情報取得部１０３が取得した発言者を識別する識別情報やプレゼンス情報を参照し、上記コンテンツに対応付けて記録する。通信内容データ記録制御部１０９によるコンテンツへの対応付けの詳細については、図３に示すフローチャートを参照して後述する。 When the communication content data recording control unit 109 receives a recording start operation by the operation unit 108 via the input interface unit 106, the communication content data recording control unit 109 records the content input from the reception content data control unit 104 or the input content data control unit 105 in the recording unit 110. To do. When recording, the communication content data recording control unit 109 refers to identification information or presence information for identifying a speaker acquired by the session information acquisition unit 103, and records it in association with the content. Details of the correspondence to the content by the communication content data recording control unit 109 will be described later with reference to the flowchart shown in FIG.
　記録データ再生制御部１１１は、記録部１１０に記録されたコンテンツを再生し、出力インタフェース１１２を介して接続される音声出力部１１３や表示部１１４にそのコンテンツを出力させる。 The recorded data reproduction control unit 111 reproduces the content recorded in the recording unit 110 and causes the audio output unit 113 and the display unit 114 connected via the output interface 112 to output the content.
　次に、本発明の実施の形態の通信端末による一連の処理の流れを、図３に示す、本発明の実施の形態の通信端末による処理の流れを示すフローチャートを参照して、説明する。なお、ここでは、ＰｏＣを利用した音声通話を実施する場合の通信端末による処理について説明する。 Next, a flow of a series of processes performed by the communication terminal according to the embodiment of the present invention will be described with reference to a flowchart showing a process flow performed by the communication terminal according to the embodiment of the present invention shown in FIG. Here, processing by the communication terminal when performing a voice call using PoC will be described.
　まず、複数の通信端末の間でサーバを介したセッションが確立されているものとし、処理の開始時点ではサーバはいずれの通信端末にも発言権を付与していないものとする。サーバは、発言権を付与することを要求する発言権要求メッセージを複数の通信端末のいずれかから受信すると、セッションを確立している複数の通信端末に対して、発言権を付与した通信端末を通知するフロア権メッセージを送信するが、発言権を付与されていない通信端末は、このフロア権メッセージがサーバから通知されるのを待ち受ける（ステップ３０１）。通信端末によるフロア権メッセージの待ち受け処理は、セッションが確立されている限り（ステップ３１１、Ｎ）、継続される。 First, it is assumed that a session via a server is established between a plurality of communication terminals, and the server does not grant a speaking right to any communication terminal at the start of processing. When the server receives a floor request message requesting to give a floor from any of the plurality of communication terminals, the server assigns a communication terminal to which the floor has been granted to a plurality of communication terminals that have established sessions. The communication terminal that has transmitted the floor right message to be notified but has not been granted the right to speak waits for the floor right message to be notified from the server (step 301). The floor right message standby processing by the communication terminal is continued as long as the session is established (step 311, N).
　その後、サーバはフロア権メッセージを複数の通信端末に通知すると（ステップ３０２、Ｙ。以降の処理では、図２に示すように、サーバ２が通信端末１ａに発言権を付与する場合の処理について説明する）、通信端末は、サーバから通知されたフロア権メッセージを抽出し、そのフロア権メッセージに含まれる、サーバが発言権を付与した発言者（クライアント）を識別する識別情報を取得する（ステップ３０３）。また、通信端末は、フロア権メッセージが通知された時点での、セッションを確立している他の通信端末のプレゼンス情報を抽出し、そのプレゼンス情報に含まれる、各クライアントのステータスを取得する（ステップ３０４）。さらに、通信端末は、フロア権メッセージから取得した識別情報が自機の識別情報と一致するか否かを判別する（ステップ３０５）。 Thereafter, when the server notifies the floor right message to a plurality of communication terminals (step 302, Y. In the subsequent processing, as shown in FIG. 2, the processing when the server 2 grants the right to speak to the communication terminal 1a will be described. The communication terminal extracts the floor right message notified from the server, and acquires identification information included in the floor right message for identifying the speaker (client) to which the server has given the right to speak (step 303). ). The communication terminal extracts the presence information of other communication terminals that have established a session at the time when the floor right message is notified, and acquires the status of each client included in the presence information (step) 304). Further, the communication terminal determines whether or not the identification information acquired from the floor right message matches the identification information of the own device (step 305).
　フロア権メッセージから取得した識別情報が自機の識別情報と一致する通信端末１ａは（ステップ３０５、Ｙ）、音声入力部１０７によって入力した利用者の音声信号（送話用の音声）を、記録すべきコンテンツとして扱う。すなわち、通信端末１ａは、音声入力部１０７によって入力した音声信号をオーディオデータに変換し、コンテンツとしてのオーディオデータの記録を開始する。記録する際には、図４に示す、本発明の実施の形態の通信端末によるコンテンツへの対応付けの一例のように、そのコンテンツとしてのオーディオデータに対応付けて、発言者識別情報、時系列データ、発話時間、他の通信端末１ｂ、１ｃ、１ｄのプレゼンス情報などの属性情報を記録する（ステップ３０６）。 The communication terminal 1a in which the identification information acquired from the floor right message matches the identification information of the own device (step 305, Y) records the user's voice signal (voice for transmission) input by the voice input unit 107. Treat as content that should be. That is, the communication terminal 1a converts the audio signal input by the audio input unit 107 into audio data, and starts recording audio data as content. When recording, as shown in FIG. 4, as shown in FIG. 4, as an example of association with content by the communication terminal according to the embodiment of the present invention, speaker identification information, time series are associated with audio data as the content. Data, speech time, and attribute information such as presence information of other communication terminals 1b, 1c, and 1d are recorded (step 306).
　発言者識別情報は、発言権が付与された発言者の識別情報であり、ここでは通信端末１ａに発言権が付与されているため、図４に示すように「ユーザＡ」（ユーザＡが所持する通信端末１ａ）が対応付けられる。時系列データは、コンテンツが通信端末に記録された順序を表す情報であり、通信端末に新たなコンテンツが記録される度にその数値が大きくなる。図４では、通信端末１ａに発言権が付与されたときに記録したコンテンツが最初のコンテンツであったものとし、時系列データ「１」を割り当てている。発話時間は、あるコンテンツの記録を開始してから終了するまでの時間であり、通信端末１ａはコンテンツの記録を開始した時点を起点として計時を開始する。図４では、通信端末１ａに発言権が付与されたときのコンテンツの記録期間が「１０秒」であることを示している。プレゼンス情報は、他の通信端末１ｂ、１ｃ、１ｄのプレゼンス情報に含まれる各クライアントのステータスである。図４では、「ユーザＢ」のプレゼンス情報として「参加」が、「ユーザＣ」のプレゼンス情報として「不参加」が、「ユーザＤ」のプレゼンス情報として「参加」が、それぞれ割り当てられている。 The speaker identification information is the identification information of the speaker to whom the right to speak is given, and here, since the right to speak is given to the communication terminal 1a, as shown in FIG. Communication terminal 1a) to be associated. The time-series data is information indicating the order in which the contents are recorded on the communication terminal, and the value increases each time new content is recorded on the communication terminal. In FIG. 4, it is assumed that the content recorded when the floor is granted to the communication terminal 1a is the first content, and time-series data “1” is assigned. The utterance time is the time from the start of recording of a certain content to the end, and the communication terminal 1a starts measuring time from the time when recording of the content is started. FIG. 4 shows that the content recording period when the right to speak is granted to the communication terminal 1a is “10 seconds”. Presence information is the status of each client included in the presence information of the other communication terminals 1b, 1c, and 1d. In FIG. 4, “participation” is assigned as presence information of “user B”, “non-participation” is assigned as presence information of “user C”, and “participation” is assigned as presence information of “user D”.
　一方、フロア権メッセージから取得した識別情報が自機の識別情報と一致しない通信端末１ｂ、１ｃ、１ｄは（ステップ３０５、Ｎ）、サーバ２を介して通信端末１ａから受信したオーディオデータ（すなわち、受話用の音声）を、記録すべきコンテンツとして扱う。すなわち、通信端末１ｂ、１ｃ、１ｄは、受信内容データ制御部１０４によって復号化したコンテンツとしてのオーディオデータに対応付けて、発言者識別情報、時系列データ、発話時間、他の通信端末のプレゼンス情報などの属性情報を記録する（ステップ３０７）。図４では、通信端末１ａによるコンテンツへの対応付けを示しているが、例えば通信端末１ｂによるコンテンツへの対応付けでは、通信端末１ａも同様に記録している同一のコンテンツに対して、発言者識別情報及び発話時間は同一の情報になり、時系列データ、他の通信端末のプレゼンス情報については異なるもの、すなわち、時系列データにはそれまでに通信端末１ｂが記録したコンテンツの順序に応じた数値が、他の通信端末のプレゼンス情報には通信端末１ｂ、１ｃ、１ｄのステータスが、それぞれ割り当てられる。 On the other hand, the communication terminals 1b, 1c, 1d whose identification information acquired from the floor right message does not match the identification information of the own device (step 305, N) are the audio data received from the communication terminal 1a via the server 2 (ie, (Receiving voice) is handled as content to be recorded. That is, the communication terminals 1b, 1c, and 1d are associated with the audio data as the content decoded by the received content data control unit 104, and the speaker identification information, the time series data, the utterance time, and the presence information of other communication terminals Etc. are recorded (step 307). Although FIG. 4 shows the correspondence to the content by the communication terminal 1a, for example, in the correspondence to the content by the communication terminal 1b, the speaker for the same content recorded in the communication terminal 1a in the same manner The identification information and the utterance time are the same information, and the time series data and the presence information of other communication terminals are different, that is, the time series data corresponds to the order of the contents recorded by the communication terminal 1b so far. The numerical values are assigned to the status information of the other communication terminals, and the statuses of the communication terminals 1b, 1c, and 1d are respectively assigned.
　なお、コンテンツの記録を終了するまでに通信端末のプレゼンス情報が更新された場合には（ステップ３０８、Ｙ）、その通信端末に対応するプレゼンス情報を上書きする、あるいは、更新される前後のプレゼンス情報をそれぞれ記録する、ようにしてもよい（ステップ３０９）。 If the presence information of the communication terminal is updated by the end of content recording (step 308, Y), the presence information corresponding to the communication terminal is overwritten, or presence information before and after the update is updated. May be recorded (step 309).
　その後、通信端末１ａは、利用者の音声信号の入力を終了し、計時した時間間隔を発話時間として記憶するとともに、付与されていた発言権を解放することを通知する発言権解放メッセージをサーバ２に送信する（ステップ３１０、Ｙ）。通信端末１ａは、発言権解放メッセージをサーバ２に送信するまでは（ステップ３１０、Ｎ）、ステップ３０５からステップ３１０までの処理を繰り返す。その後、サーバは、発言権をいずれの通信端末にも付与していないことを通知するフロア権メッセージを複数の通信端末に通知すると、発言権を付与することを要求する発言権要求メッセージの待ち受けを開始する。一方、発言権を付与されていない通信端末１ａ、１ｂ、１ｃ、１ｄは、再度、発言権を付与した通信端末を通知するフロア権メッセージがサーバから通知されるのを待ち受けることになる（ステップ３０１）。このようにして、通信端末１ａ、１ｂ、１ｃ、１ｄは、発言権が任意の通信端末に付与される毎に、その通信端末を識別する識別情報に対応させて、発言権が当該通信端末に付与されている期間中に入力したコンテンツを記録する。図４では、上述の処理の後、さらに、通信端末１ａが、発言権を付与された通信端末１ｂから受信した音声信号をコンテンツとして記録する際の例も示しており、そのコンテンツには、発言者識別情報として「ユーザＢ」が、時系列データとして「２」が、発話時間として「２０秒」が、「ユーザＢ」のプレゼンス情報として「参加」が、「ユーザＣ」のプレゼンス情報として「参加」が、「ユーザＤ」のプレゼンス情報として「参加」が、それぞれ対応付けられている。 Thereafter, the communication terminal 1a ends the input of the voice signal of the user, stores the time interval counted as the utterance time, and sends a utterance right release message for notifying that the assigned utterance right is released to the server 2 (Step 310, Y). The communication terminal 1a repeats the processing from step 305 to step 310 until a speaking right release message is transmitted to the server 2 (step 310, N). After that, when the server notifies a plurality of communication terminals of a floor right message notifying that no communication right has been given to any communication terminal, the server waits for a right to request the right to speak. Start. On the other hand, the communication terminals 1a, 1b, 1c, and 1d that have not been granted the right to speak again wait for the floor right message notifying the communication terminal to which the right to speak has been notified from the server (step 301). ). In this way, each time the communication terminal 1a, 1b, 1c, 1d is granted a right to speak to any communication terminal, the right to speak is assigned to the communication terminal corresponding to the identification information for identifying the communication terminal. Record the content entered during the granted period. FIG. 4 also shows an example in which the communication terminal 1a records the audio signal received from the communication terminal 1b to which the right to speak is recorded as content after the above-described processing. “User B” as the person identification information, “2” as the time series data, “20 seconds” as the utterance time, “Participation” as the presence information of “User B”, and “Presence information of“ User C ”as“ Presence information ” “Participation” is associated with “Participation” as presence information of “User D”.
　上述のようにコンテンツを記録した後、複数の通信端末の間での確立していたセッションが開放されると（ステップ３１１、Ｙ）、通信端末は、フロア権メッセージの待ち受け処理を終了する。なお、通信端末は、あるセッションが確立されて開放されるまでに記録されたコンテンツを関連のあるコンテンツ群とみなし、それらのコンテンツを合成し、一つのデータ単位として再度記録するようにしてもよい。これは、ＰｏＣを利用した音声通話を例に考えると、各利用者による一度の発話が一つのコンテンツに相当し、セッションが開放されるまでの一度の音声通話（音声通話は、複数の利用者による複数回の発言によって成り立つ。）がコンテンツ群に相当することを意味する。音声通話単位でコンテンツを記録することにより、その音声通話を再生するときに通話内容を思い出すことが容易になる。 When the session established between the plurality of communication terminals is released after the content is recorded as described above (step 311, Y), the communication terminal ends the floor message waiting process. Note that the communication terminal may regard content recorded until a session is established and released as a related content group, synthesize these contents, and re-record them as one data unit. . Considering a voice call using PoC as an example, one utterance by each user corresponds to one content, and a single voice call until a session is released (voice call is made up of multiple users) This means that it is equivalent to a content group. By recording content in units of voice calls, it becomes easy to remember the contents of the call when playing back the voice call.
　その後、通信端末１ａは、記録したコンテンツの一覧を表示する操作を受け付けると、コンテンツの属性情報として、発言者識別情報、時系列データ、発話時間、他の通信端末１ｂ、１ｃ、１ｄのプレゼンス情報を表示することによって、再生を希望するコンテンツ（あるいはコンテンツ群）の選択をユーザに促し、選択されたコンテンツを再生する操作を受け付ければ（ステップ３１２、Ｙ）、当該コンテンツの再生を開始する（ステップ３１３）。このように、通信端末が属性情報とともにコンテンツを記録しておくことによって、当該コンテンツを通信端末が再生する際に、当該コンテンツの属性情報をユーザに通知することができるため、ユーザは記録しておいたコンテンツの内容を容易に思い出すことができる。通信端末は、再度、複数の通信端末の間でサーバを介したセッションが確立されれば（ステップ３１４、Ｙ）、ステップ３０１の処理に戻って上述した処理を繰り返すことになる。 Thereafter, when the communication terminal 1a accepts an operation for displaying a list of recorded contents, as the attribute information of the contents, speaker identification information, time series data, speech time, presence information of other communication terminals 1b, 1c, and 1d Is displayed to prompt the user to select the content (or content group) desired to be reproduced, and if an operation for reproducing the selected content is accepted (step 312, Y), reproduction of the content starts (step 312). Step 313). As described above, since the communication terminal records the content together with the attribute information, when the communication terminal reproduces the content, the user can be notified of the attribute information of the content. You can easily remember the contents of the contents. If a session via a server is established again among a plurality of communication terminals (step 314, Y), the communication terminal returns to the process of step 301 and repeats the above-described process.
　以上、本発明の実施の形態の通信端末によれば、ＰｏＣサーバへ送信するコンテンツまたはＰｏＣサーバから受信したコンテンツをＰｏＣクライアントが当該コンテンツに関する属性情報とともに記録することによって、当該コンテンツを通信端末が再生する際に、当該コンテンツの属性情報をユーザに通知する。これにより、当該コンテンツを通信端末が再生する際に、当該コンテンツの属性情報をユーザに通知することができ、その記録しておいたデータを再生するときの利用者の利便性を向上させることができる。 As described above, according to the communication terminal of the embodiment of the present invention, the content transmitted to the PoC server or the content received from the PoC server is recorded together with the attribute information related to the content by the PoC client, so that the communication terminal reproduces the content. In doing so, the user is notified of the attribute information of the content. As a result, when the communication terminal reproduces the content, the user can be notified of the attribute information of the content, and the convenience of the user when reproducing the recorded data can be improved. it can.
　なお、本発明の実施の形態では、セッションを確立している通信端末のいずれかに発言権が付与された後、自機に発言権が付与された場合には自機が入力するコンテンツを、他機に発言権が付与された場合には他機から受信するコンテンツ、それぞれ記録する処理について説明した。これに加えて、他機に発言権が付与された場合であっても、自機が入力するコンテンツを記録するようにしてもよい。例えば、ＰｏＣによる音声通話を複数の通信端末の間で行っている場合を考えると、発言権が付与された他の通信端末から受信するオーディオデータを一つのコンテンツとして記録するとともに、自機によって入力するオーディオデータを別のコンテンツとして記録する。前者のオーディオデータの内容は、実施中の音声通話によって交わされる会話であり、後者のオーディオデータの内容は、実施中の音声通話の通話相手に伝わることの無い、自分自身へのメモ録音や独り言になる。 In the embodiment of the present invention, after the right to speak is given to any of the communication terminals that have established a session, the content input by the own device when the right to speak is given to the own device, The processing for recording the content received from the other device when the right to speak is given to the other device and the respective processing has been described. In addition to this, even when the right to speak is granted to another device, the content input by the own device may be recorded. For example, when considering a case where a voice call based on PoC is performed between a plurality of communication terminals, audio data received from another communication terminal to which a right to speak is recorded as one content and input by the own device The audio data to be recorded is recorded as another content. The content of the former audio data is a conversation exchanged by the ongoing voice call, and the content of the latter audio data is not recorded to the other party of the ongoing voice call and can be recorded to the memo or self-speaking. become.
　本発明を詳細にまた特定の実施態様を参照して説明したが、本発明の精神と範囲を逸脱することなく様々な変更や修正を加えることができることは当業者にとって明らかである。 Although the present invention has been described in detail and with reference to specific embodiments, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention.
　本発明の通信端末及びデータ記録方法によれば、ＰｏＣサーバへ送信するデータまたはＰｏＣサーバから受信したデータを記録するＰｏＣクライアントによって、その記録しておいたデータを再生するときの利用者の利便性を向上させることができるという効果を奏し、ＰｏＣサーバとの間で通信を行う通信端末に関する分野において有用である。 According to the communication terminal and the data recording method of the present invention, the convenience of the user when reproducing the recorded data by the PoC client that records the data transmitted to the PoC server or the data received from the PoC server. This is effective in the field of communication terminals that communicate with a PoC server.
