Description

  The present invention relates to an electronic conversation technique in which a plurality of speakers communicate with each other via their own terminals. For example, it is suitable for use in PoC (Push-to-Talk over Cellular).

  An operation time chart of the conventional electronic conversation service is shown in FIG. One form of this electronic conversation service is a service called PoC (Push-to-Talk over Cellular). In PoC, one-to-many voice transmission can be performed by half-duplex communication.

FIG. 12 shows a case where speakers A, B, and C are users of terminals A, B, and C, respectively, and speaker A now wants to start a conversation with speakers B and C. (1) When a conversation participation request addressed to terminals B and C is transmitted from the terminal A to the conversation server, (2) the conversation server transfers the conversation participation request from the terminal A to the terminals B and C. When the terminals B and C receive the conversation participation request, they notify the speakers B and C, respectively, that the conversation participation request has been received from the terminal A by sound or screen display. Here, if the speaker B participates in the conversation but the speaker C does not participate in the conversation, (3) a conversation participation consent is transmitted from the terminal B, and nothing is transmitted from the terminal C. When the conversation server (4) transfers the conversation participation approval from the terminal B to the terminal A, the conversation between the speaker A and the speaker B is performed between the terminal A and the terminal B (for example, Non-Patent Document 1, Patent References 1-3).
Published by Ericsson, Motorola, Siemens, Nokia, "PoC Architect; PoC Release 1.0", [online], [Search January 29, 2004], Internet <URL: http: // www. ericsson. com / multiservicenetworks / distr / PoC_specificatios. ZIP> JP 2002-91883 A JP 2002-116766 A JP 2003-16288 A

  However, since the conventional electronic conversation service represented by PoC does not have a function of recording the conversation content, the conversation content cannot be checked again after the conversation ends (for example, see Non-Patent Document 1). That is, the speaker C who has been invited to participate in the conversation cannot participate in the conversation and can no longer know the content of the conversation later.

  In addition to this, for example, Patent Documents 1, 2, and 3 disclose a technique for recording acquired content data and transferring the recorded content data to another. It is not a technique for recording.

  The purpose of the present invention is also for speakers who have been invited to participate in a conversation but who have not been able to participate in the conversation at the time, or who have not been invited to the conversation but who have decided that it is necessary to hear this conversation later. To be able to provide conversational content.

  In order to solve such a conventional problem, the applicant of the present application has proposed a technique for recording conversation contents in a multi-user electronic conversation service such as PoC (Japanese Patent Application No. 2004-39939: application filed in this application). Sometimes unpublished).

  The present invention is premised on this recording technique, and a user who has not participated in a conversation or a user who has participated in a conversation, but who wants to check the recording of the conversation can take out and listen to the contents of the conversation after the conversation ends.

Means no. When the conversation log is confirmed (already displayed), the presence of the conversation log after the display for a certain period of time is deleted from the server (11) and disappears.

(Third embodiment)
As a third embodiment, the basic configuration is the same as that of the first embodiment, but it is further devised for notification of a conversation log and confirmation of opening for a participant who could not participate in the conversation. For users who could not participate in the conversation, e-mail is used to notify that there is an unread conversation log regarding the conversation that they could not participate in.

  This method is realized by registering a mail address in advance in a mail server linked with the conversation server 10. Although not shown in the configuration diagram of FIG. 1, this mail server may be provided inside the conversation server 10 or may be separately provided as an external device of the conversation server 10. In any case, the notification unit 4 and the mail server are linked. In the third embodiment, the user who participates in the conversation and discloses the conversation log is notified by e-mail after opening the conversation log of the user who does not participate in the conversation.

  Next, the operation procedure of the third embodiment will be described with reference to FIG. FIG. 6 is a time chart showing an example of the conversation log reproduction system operation of the conversation server 10 of the third embodiment. In this example, the four speakers A, B, C, and D have terminals A, B, C, and D, respectively, and the speaker A requests a conversation with the speakers B and C and participates in the conversation. After the conversation between the speaker A and the speaker B is completed, the case where the speaker A allows the speaker C and the speaker D who are not participating in the conversation to reproduce the conversation log is described. However, in this embodiment, it is assumed that the mail address of the mobile phone owned by each speaker is registered in the mail server linked to the conversation server 10 before the service is started.

  The operation will be described step by step. When the speaker A operates the terminal A to have a conversation between the speakers B and C, (1) the terminal A transmits to the conversation server 10 that the conversation between the terminal B and the terminal C is to be started. (2) The member registration unit 2 of the conversation server 10 registers itself that the members participating in the conversation are A, B, and C, and forwards the conversation participation request from the terminal A to the terminal B and the terminal C. To do.

  When receiving the conversation participation request, the terminals B and C inform the speakers B and C, which are terminal users, that the conversation participation request from the speaker A has been received, respectively, by sound and screen display. Here, it is assumed that speaker B participates in the conversation, but speaker C cannot participate in the conversation for some reason. At this time, (3) Conversation participation consent is transmitted from the terminal B to the member registration unit 2 of the conversation server 10, but the terminal C does not transmit anything.

  The member registration unit 2 of the conversation server 10 that has received the conversation participation consent from the terminal B (4) transfers the conversation participation consent from the terminal B to the terminal A. By the procedure so far, it is confirmed that the terminal A and the terminal B participate in the conversation, and (5) the conversation is performed between both terminals.

  At this time, the conversation log storage unit 1 of the conversation server 10 stores the conversation log by recording the contents of the conversation between the terminal A and the terminal B. When the conversation between the terminal A and the terminal B ends, (6) the terminal A transmits to the conversation server 10 permission to disclose the conversation log to the terminal D.

  (7) The notification unit 4 of the conversation server 10 searches the non-participant search unit 3 to find out that the terminal C is a non-participant, and notifies the terminal C that the conversation log is stored (conversation log alarm provision At the same time, the terminal D is also informed that the conversation log is being saved in response to a request from the terminal A.

  At this time, in the third embodiment, the fact that the conversation log is stored is notified to the terminals C and D from the mail server linked with the notification unit 4 of the conversation server 10.
