Description

  The present invention relates to a conversation system, a conversation method, a conversation server, and a program, and more particularly, to a conversation system, a conversation method, a conversation server, and a program that perform conversation between multiple users using a network and a plurality of terminals.

  There is a service called PoC (Push-to-Talk over Cellular) as one of conversation systems that perform conversations between multiple users using a network and a plurality of terminals. PoC is a technology that uses a mobile phone like a transceiver, and enables 1-to-N (multiple) communication. For example, the service is provided by Nextel in the United States. There are several PoC implementation methods, but the basic mechanism is the same, and consists of a PoC server with a session management function and a floor control function, and a GLMS (Group List Management Server) that manages the group list (for example, non- Patent Document 1). In this specification, terms are used according to Non-Patent Document 1. The terminal in this specification corresponds to what is called UE in Non-Patent Document 1.

  Since PoC is a means for performing real-time communication, when performing group communication, a user who cannot participate in PoC communication at that time, such as a user outside the service area, cannot participate in communication.

  The applicant of the present application has proposed a method for recording PoC communication content in Japanese Patent Application No. 2004-039939. In this system, it is possible to record communication contents including off-record communication by providing means for flexibly changing whether or not to record. In addition, as a method for listening to recorded communication contents, Japanese Patent Application No. 2004-092566 describes a method of referring to recorded contents after communication, but does not consider reuse in another session. .

  Since the conventional conversation system described above is a means for performing real-time communication, information such as previous conversations that exist in the network cannot be reused from other sessions or other terminals. There was a point.

  In addition, when quoting information such as conversations that have been performed before, it is not clearly indicated that the data is to be reused, and there is a problem in that the user who receives the data does not know which statement is to be reused.

  In addition, when quoting information such as a conversation that has been performed before, the speaker and the time of the statement are not specified, and thus there is a problem that the user who received the data does not know when or who sent (sent).

  In addition, when it is possible to reuse information such as conversations that have been performed previously, there is no means for determining whether or not reuse is possible, and thus there is a problem in that it is not possible to limit the diversion.

  Also, if it is possible to reuse information such as previously conducted conversations, copying the same data when logging will result in the loss of information such as which session the citation was from, and storage There is a problem that the size of the storage area is excessive.

  The best mode for carrying out the present invention will be described in detail with reference to the drawings. The present invention records a conversation log in a storage device in a conversation system that performs group communication among multiple users using a plurality of terminals, represented by PoC. A conversation log taken in a previous session, a participating session, or a session that is being performed in parallel can be delivered during the session in the middle of a PoC conversation. Information about the conversation log quoted at that time (sender, speech time, etc.) is also provided to the receiver at the same time. In addition, media information created outside the conversation system can also be cited. In the following description, an example in which the conversation system is PoC will be described.

  FIG. 1 is a block diagram showing the configuration of the first embodiment of the present invention. An operation flow (to be described later with reference to FIG. 3) is also shown in the drawing so that the relationship between the blocks becomes clear. The first embodiment includes a conversation server 10, a terminal A 20a, a terminal B 20b, a terminal C 20c, and a network 100 that connects these to each other. The Internet is generally used as the network 100. Although FIG. 1 shows an example including three terminals, the number is not limited to this, and any number of terminals can be configured as long as the number is one or more. In the following description, the terminal A20a, the terminal B20b, and the terminal C20c are simply referred to as the terminal 20 unless particularly distinguished.

  The conversation server 10 includes a session management unit 11, a determination unit 12, a determination rule 13, a recording unit 14, a conversation log storage unit 15, a browsing processing unit 16, and a transmission processing unit 17. These units do not need to be included in one conversation server 10 and may be distributed to a plurality of servers. For example, you may distribute to the PoC server containing the session management part 11, the log server containing the recording part 14 and the conversation log preservation | save part 15, and the quotation server containing the browsing process part 16 and the transmission process part 17. Further, a log storage citation server including the functions of the log server and the citation server may be used.

  The session management unit 11 has functions normally provided in the PoC server, such as a session management function and a floor control function.

  The determination unit 12 determines whether or not a certain session is a recording target based on the determination rule 13 stored in the storage device.

  The recording unit 14 records the communication data and additional data received from the session management unit 11 in the conversation log storage unit 15 as a conversation log according to the result of the determination unit 12. The conversation log storage unit 15 is a storage device.

FIG. 2 is a diagram illustrating a configuration example of a conversation log stored in the conversation log storage unit 15. The conversation log storage unit 15 holds a conversation log including the following data as a result of writing the communication data and additional data by the recording unit 14. Although it is assumed that these data are divided for each PoC utterance, they may be divided by other methods.
(1) Session identifier: an identifier for identifying a session storing data.
(2) Caller identifier: An identifier for identifying a user who has spoken data.
(3) Sequence: Permutation number of data in session.
(4) Communication data: Data stored in a previous session or a session in which the session was attended.

This data is obtained by dividing the content of a statement during one session into a plurality of data, for example, by pressing the press talk switch until the user speaks and speaks. As another example, the data may be created by a method not related to the session.
(5) Other information: Additional information about communication data. Speaker, utterance time, utterance time, sequential number in utterance session, utterance group name, media type before conversion, utterance sequence number, etc.
(6) Citation restriction flag: Includes the following three flags.
(6-a) Non-person reusability flag: A flag indicating whether a user other than the speaker who created the communication data can send the communication data to the PoC session.
(6-b) Out-of-group reuse flag: A flag indicating whether or not the communication data can be sent to the PoC session in a PoC session in a group that is not the same as the conversation group that created the communication data. .
(6-c) Out-of-session reuse flag: A flag (6-d) indicating whether the communication data can be sent to a session other than the PoC session in which the communication data is currently being created. Data available user list valid flag: A flag indicating whether or not the “data available user list” that holds a list of users that can transmit this communication data in the PoC session is valid. If it is invalid, the data available user list is not used. The “data available user list” holds a list of users who can send the communication data in the PoC session, and is included in the conversation log storage unit 15.

  As another implementation method, as described above, the conversation log storage unit 15 not only stores information remarked in the previous session as communication data, but also stores data created by other methods. May be.

  In accordance with an instruction from the terminal 20, the browsing processing unit 16 accesses the conversation log storage unit 15 to search for data to be cited, and returns the result to the user via the terminal 20. In addition, the browsing processing unit 16 receives a data transmission instruction from the terminal A 20a, reads communication data and additional data from the conversation log storage unit 15, and then transmits to the transmission processing unit 17 communication data and addition to the PoC session. Instruct to send data.

  The transmission processing unit 17 receives an instruction, communication data, and additional data from the browsing processing unit 16, and transmits these data to the session by communicating with the session management unit 11.

  The terminal 20 is a mobile phone or the like, and includes a button for inputting data, a voice input / output unit, a display unit for displaying data on the screen, and the like. The terminal 20 has a function that can use a basic PoC service. Further, the terminal 20 has an interface with the browsing processing unit 16, and can perform a search to cite the communication data stored in the conversation log storage unit 15. Further, the terminal 20 has a function of instructing the browsing processing unit 16 to send the communication data and additional data obtained as a result of the search to the currently participating session. Furthermore, the terminal 20 has a function of presenting additional information related to a function of displaying that the communication data and additional data cited are displayed as the cited information to the user.

  Next, the operation of the first embodiment will be described. FIG. 3 is a flowchart showing an operation for recording communication data.

  The session management unit 11 receives communication from the caller via the terminal 20 (step A1).

  The session management unit 11 requests the determination unit 12 to determine whether the received communication content should be recorded (step A2).

  The determination unit 12 determines whether recording is necessary based on the determination rule 13 held, and returns the determination result to the session management unit 11 (step A3).

  When the session management unit 11 receives the determination result that the communication content needs to be recorded from the determination unit 12, the session management unit 11 requests the recording unit 14 to record the communication data (step A4).

  When receiving a request from the session management unit 11, the recording unit 14 records the communication data together with additional data such as a session identifier and a caller identifier in the conversation log storage unit 15 as a conversation log (step A5).

  The session management unit 11 transmits communication data to the session participation terminal 20 (step A6).

  Note that the processing order is not limited to the above, and the recording processing in steps A4 to A5 and the distribution processing in step A6 may be performed in parallel. Further, the order of the recording process in steps A4 to A5 and the distribution process in step A6 may be reversed.

  The determination rule 13 is a conditional expression for determining whether it is necessary to record the communication contents of the session. Depending on the determination rule, it is also possible to record only specific communication contents during the session. The details of the determination rule are not the main part of the present invention, and will not be described in detail here.

  FIG. 4 is a flowchart showing an operation of quoting recorded communication data. It is assumed that the terminal A 20a, the terminal B 20b, and the terminal C 20c are participating in the session according to the operation of the conversation server 10.

  In order to search, the terminal A20a requests information for data selection from the browsing processing unit 16 (step B1).

  The browsing processing unit 16 accesses the conversation log storage unit 15 and reads information presentation of the conversation log (step B2).

The browsing processing unit 16 determines whether or not citation is possible based on the citation restriction flag included in the obtained information (step B3). Based on this determination, the range of citations is limited to the same group as the recording, within the transmitted session, the specified individual user, the speaker at the time of recording, and the like. In step B3, the following judgments (1) to (4) are made. The order does not matter.
(1) The reusability flag other than the principal is checked. If the answer is negative, it is checked whether the sender of the data to be quoted is the same as the user to be quoted. to approve.
(2) Check the reusability flag outside the group, and if not, if the group name of the currently participating session matches the group name of the session when the recorded data is saved, Can be quoted.
(3) The non-session reusability flag is checked, and if not, quoting is possible if the session of communication data to be cited is the same as the currently participating session.
(4) When the data available user list valid flag is enabled, it is checked whether or not the user who is going to quote is registered in the data available user list. And

  The browsing processing unit 16 accesses the conversation log storage unit 15 and sends a list of communication data remarked in the selected session to the terminal A 20a (step B4). Each communication data is assigned a reference, and the browsing processing unit 16 can read the corresponding communication data by giving the reference to the conversation log storage unit 15 as a key. The contents displayed as a list on the terminal A 20a are as follows, but other contents are also possible. Communication data start time, end time, utterance time, utterance permutation number, speaker, data format (voice, image, video, etc.), group name.

The user selects and decides necessary information from the list information displayed on the terminal A 20a with a cursor or the like. As for the selected information, the terminal A 20a performs the following procedure (1) or (2), so that an instruction to send communication data to the session is sent to the browsing processing unit 16 (step B5). A reference is given to the transmission instruction, and the communication data is specified thereby.
(1) Next, when the press talk button is pressed, it is sent to the browsing processing unit 16.
(2) Stored in the bookmark list on the terminal A 20a, and sent to the browsing processing unit 16 when selected again from the bookmark during a call.

  In response to the transmission instruction received from the terminal A 20a, the browsing processing unit 16 reads the corresponding communication data and additional data from the conversation log storage unit 15 using the reference as a key (step B6).

  The browsing processing unit 16 sends the read communication data and additional data to the transmission processing unit 17 together with a transmission instruction (step B7).

  The transmission processing unit 17 communicates with the session management unit 11 to acquire the floor right, and transmits the communication data and additional data received from the browsing processing unit 16 to the currently participating session through the session management unit 11. Send (step B8).

The terminal A 20a, the terminal B 20b, and the terminal C 20c provide the recording data and additional data received from the transmission processing unit 17 via the session management unit 11 to the user. The terminal A20a, the terminal B20b, and the terminal C20c notify the user that the information sent from the session management unit 11 is cited information using the following method (1) or (2).
(1) Characters, images, and icons representing citations are displayed on the display unit of each terminal 20.
(2) The quotation information is presented on each terminal 20, and at the same time, sound, voice, music, and the like representing the quotation information are reproduced.
In addition to this, each terminal 20 displays additional data to the user. The additional data is transferred to the transmission processing unit 17 together with the communication data. The additional data includes the start time, end time, utterance time, utterance permutation number, speaker, data format (sound, image, video, etc.) of the communication data. These pieces of information are displayed on the display unit of each terminal 20.

  If the history is stored in the session to which the cited data is sent, the session management unit 11 sends the additional data sent from the transmission processing unit 17 to the recording unit 14 (step B9). .

  When the recording unit 14 receives this information, when recording the data, the recording unit 14 stores the reference in the additional data, not the information exchanged in the session itself, in the conversation log storage unit 15 (step B10). ).

  In the present embodiment, the conversation log storage unit 15 is placed, and there is a transmission processing unit 17 that accesses and sends the communication data to the PoC session. Therefore, the communication data is also used from other sessions and other terminals. It becomes possible to do.

  In addition, since the quotation is displayed on the terminal, the user can recognize that the data is the quotation information. Further, the user can easily recognize the citation display as an image or sound.

  Further, since the additional data of the citation data is also sent to the terminal 20 and displayed to the receiving user, the user can know who and when the citation information is what was said.

  In addition, since the conversation log storage unit 15 has a flag indicating a browsing restriction range, and the browsing processing unit 16 performs browsing limitation according to the flag, unlimited citations can be prevented.

  Also, when recording a session that has been cited, a reference to the cited communication data is saved instead of the quoted communication data itself. It is possible. It is also possible to save the data storage area.

  Next, a second embodiment of the present invention will be described. FIG. 5 is a diagram showing the configuration and operation of the second embodiment. In the second embodiment, as shown in FIG. 5, the terminal A20a is stored once in the terminal A20a without directly sending the quoted data to the session from the transmission processing unit (17 in FIG. 1). Send data to the session.

  In the flow of the second embodiment, step B7 of the first embodiment is replaced with the following steps B7a and B7b.

  The browsing processing unit 16 sends the read communication data and additional data to the terminal A 20a trying to quote (step B7a). The terminal A20a can also temporarily hold the information.

  The terminal A 20 a that has received the communication data and the additional data communicates with the session management unit 11 to acquire the floor right, and receives the session right from the browsing processing unit 16 through the session management unit 11. Communication data and additional data are sent (step B7b).

  In the second embodiment, since there is no need for the transmission processing unit (17 in FIG. 1), the configuration is simple compared to the first embodiment.

  Next, a third embodiment of the present invention will be described. FIG. 6 is a diagram showing the configuration and operation of the third embodiment. The third embodiment includes a media conversion unit 18 in addition to the configuration of the first embodiment. In the third embodiment, the media conversion unit 18 can convert and send the media format of the communication data to be sent to the session after recording.

(1) Convert information stored in text into speech.
(2) Convert information stored in voice to text.
(3) Convert information stored in text into an image.

In addition, the media conversion unit 18 can add the following information to indicate that the sent content is cited data.
(A) A specific dial tone or voice is played with respect to the voice to indicate that it is quoted data.
(B) A character, mark, moving image, or the like representing “quotation” is added to the image / moving image.

  Further, the media conversion unit 18 can embed additional information in an image or voice of communication data, and the browsing processing unit 16 can instruct the transmission to send the data to the user.

  In order to perform these operations, in the third embodiment, the following operations are added between steps B6 and B7 of the first embodiment.

  The browsing processing unit 16 sends the read communication data and additional data to the media conversion unit 18 (step B6a).

  The media conversion unit 18 changes the format of the received medium and additionally writes additional data, and then returns communication data and additional data to the browsing processing unit 16 (step B6b).

  In the third embodiment, since the media conversion unit 18 is included, it is possible to convert and send the media format of the communication data to be sent to the session. In addition, when reproducing the quoted information, it is possible to distinguish between quotes and normal utterances by playing back sound indicating that it is a quote and displaying characters, images, and videos.

  Next, a fourth embodiment of the present invention will be described. FIG. 7 is a diagram showing the configuration and operation of the fourth embodiment. The configuration may be the same as in the first or second embodiment.

  The operation of the fourth embodiment will be described. By cooperation between the terminal 20 and the session management unit 11, a speech is made for the session (step C1). The session management unit 11 sends the communication data to the recording unit 14 (step C2). The recording unit 14 stores the received communication data as history information in the conversation log storage unit 15 (step C3). Steps C1 to C3 are partially omitted in operation, but are the same as steps A1 to A5 in the first embodiment.

  The terminal A20a instructs the browsing processing unit 16 to quote by pressing a quote button (not shown) in the middle of the speech or immediately after the speech (step C4).

  The browsing processing unit 16 makes an inquiry about data reference to the conversation log storage unit 15 using the time stamp and session information at that time (step C5).
