FIG. 1 is an external view of a conference system using a mobile phone (mobile communication terminal device) according to an embodiment of the present invention, and FIG. 2 is a configuration of a conference management server (conference management device) according to the embodiment of the present invention. It is the block diagram which showed.

  In FIG. 1, the conference system according to the embodiment of the present invention wirelessly communicates with a conference management server 1 that manages conferences, user mobile phones 2, 2a, 2b, and user mobile phones 2, 2a, 2b. And the IP (Internet Protocol) network (communication network) 4 that connects the conference management server 1 and the user's mobile phones 2, 2a, 2b. Here, a conference application capable of realizing the conference system according to the embodiment of the present invention is installed on the user's mobile phones 2, 2 a, and 2 b.

  In FIG. 2, a conference management unit (conference management table holding unit) 101 of the conference management server 1 manages a conference held between mobile phones, and a conference in which information of users participating in the conference is recorded. The management table 102 is held. The session establishment unit 103 establishes a communication path between mobile phones participating in the conference using a communication control protocol, and in this embodiment, SIP (Session Initiation Protocol) is used as a communication control protocol.

  The speaker right management unit 104 manages which mobile phone among the mobile phones participating in the half-duplex communication conference system is given the speaker right. The multimedia processing unit 105 includes an audio processing unit 106 that processes audio data, a text processing unit 107 that processes text data, and an image processing unit 108 that processes images. The communication unit 109 performs transmission / reception with an external device, and the bus line 110 is a bus line that connects the units in the conference management server 1 to each other.

  Next, the operation of the above-described embodiment will be described with reference to FIGS. FIG. 3 is a flowchart showing a procedure in which the user C enters the room on the way when the user A who is the convener performs the conference X with the users B and C who are the convener. First, the conference application is started up on the mobile phone 2 owned by the user A, and the user B and the user C are designated as conference participants from the address book, outgoing / incoming call history, and the like (step S101).

  Subsequently, when the cellular phone 2 of the user A transmits a convocation message for the conference X (step S102), the communication unit 109 of the conference management server 1 receives the convocation message. The invitation message received by the communication unit 109 is confirmed by the session establishment unit 103, and the session establishment unit 103 transmits the invitation message to the destination users B and C via the communication unit 109 (steps S103 and S104). ). When the mobile phone 2a of the user B receives the conference X invitation message, the conference application is activated and displays that the user A has been invited on the display. When the user B participates in the conference X, the user B responds to the received invitation message (step S105).

  On the other hand, when the mobile phone 2b of the user C receives the conference X invitation message, the conference application is similarly activated. At this time, when the user C is not driving and cannot respond to the convocation message, the user C's mobile phone 2b automatically transmits a pre-set conference participation message (conference participation impossible message transmission means). Step S106), it is possible to explicitly indicate that the user cannot participate in the conference. At this time, the mobile phone 2b of the user C creates the conference participation history shown in FIG. 4 and stores that it did not respond to the conference X (step S107).

  The response message from the mobile phone 2a of the user B and the conference participation impossible message from the mobile phone 2b of the user C are processed by the session establishment unit 103 of the conference management server 1, and the user A and the user B join the conference X. , Information indicating that the user C does not participate is output to the conference management unit 101. The conference management unit 101 writes the information of the conference X in the conference management table 102 based on the information input from the session establishment unit 103 (step S108). Here, the information of the user C who does not participate in the conference X as shown in FIG. 5 is also recorded in the conference management table. However, since the user C is not charged at this time, the process in the conference management server 1 is not complicated by adding the information of the user C.

  Thereafter, when the session establishing unit 103 establishes a session between the user A and the user B, the conference X is started (step S109). When the conference X is started, the conference progresses by exchanging voice data, text data, image data, and the like in a half-duplex manner between the user A and the user B. Here, the voice data is processed by the voice processing unit of the conference management server 1, and the voice data is transmitted and received according to the speaker right assigned by the speaker right management unit 104. The text data is processed by the text processing unit 107, and the image data is processed by the image processing unit 108.

  Next, a procedure when the user C enters the conference X halfway after the start of the conference X will be described. When the user C is ready to participate in the conference X, the conference application is activated on the mobile phone 2b, and the conference participation history in FIG. 4 is referred to. The telephone number of the contributor (user A) of the conference X is acquired from the conference participation history, and a midway entry request message for requesting midway entry to the conference X is transmitted to the user A (step S110). The midway entry request message includes identification information (telephone number or the like) of the user C and conference information (conference X) for which midway entry is desired.

  The midway entry request message from the user C is received by the communication unit 109 of the conference management server 1 and processed by the conference management unit 101. The conference management unit 101 refers to the conference management table 102 of FIG. 5 and confirms whether or not the user C is registered as a non-responder in the section of the conference X (halfway entry permission determination means, step S111). When the user C is registered as a non-responder in the conference participation table, the conference management unit 101 stores information on the conference X held between the user A and the user B while the user C is not participating. Is transmitted to the mobile phone 2b of the user C (conference information transmitting means, step S112). Here, the information on the conference X includes the start time and duration of the conference X, the presence / absence of continuation, information on participants of the conference X, and the like.

  As described above, in the present embodiment, since a means for giving permission to enter the room on the way only to the user convened by the meeting convener (user A) is taken, other users who are not invited are on the way to the meeting. I cannot enter the room. Therefore, it is possible to ensure the security of the conference as in the prior art.

  When the mobile phone 2b of the user C receives the information on the conference X from the conference management server 1, the user C confirms the content, selects whether to request to enter the conference X halfway, or to cancel it. Is transmitted (step S113). At this time, when the user C selects not to enter the room on the way and transmits a message to that effect to the conference management server 1, all participants including the user A who is the conferee of the conference or the invitee (user B) Thus, the conference management server 1 can also notify that the user C does not enter the conference halfway. When the communication unit 109 of the conference management server receives a message for requesting mid-room entry, the message is processed by the conference management unit 101, and the user C who has been invited to the conference X is allowed to request mid-room entry of the user C. An inquiry is made as to whether to do so (step S114). When the user A permits the user C to enter the room on the way (step S115), the conference management server 1 notifies the user C of the room entry permission to the meeting X (step S116). Here, it is also possible for the conference management server 1 to notify other participants (user B) of the conference that the user C has been allowed to enter the room on the way.

  After entering the room on the way, the conference X is held among the three users, user A, user B, and user C (step S117). In the conference management table 102 in the conference management server 1, information is changed from a non-response attendee to a normal attendee, and the user C is also billed thereafter. After the user C enters the room, history log information such as voice data, text data, and image data exchanged between the user A and the user B at the conference X is transmitted from the conference management server 1 to the mobile phone 2b of the user C. (Conference history information transmission means, step S118). The history log information transmitted here is more detailed information than the conference information transmitted in step S112. The user C can participate in the conference X while grasping the content of the conference X held so far by appropriately referring to the transmitted history log information.

  Although the embodiments of the present invention have been described in detail above, the specific configuration is not limited to the above-described embodiments, and design changes can be made without departing from the scope of the present invention. Further, the above embodiments include inventions at various stages, and various inventions can be extracted by appropriately combining a plurality of disclosed constituent elements.

In the case of being obtained, a configuration from which the configuration requirements are deleted can be extracted as an invention.

  Specifically, it is not always necessary to report the meeting status in step S112 and request to enter (or cancel) in the middle of step S113, and the conference management server 1 confirms permission to enter the room (user A) ( Steps S114 and S115) are not necessarily required. Registration in the conference management table 102 in step S111 may be used as a condition for permitting mid-room entry, and step S112 to step S115 may be omitted to permit user C to enter mid-room.

  Further, step S106 is not necessarily required to send a notice to the attendee C when he / she cannot participate in the conference X, and the conference management server 1 stores it in the conference management table as a non-responder when there is no response to the conference invitation. It is also possible. Furthermore, step S118 in which the user C transmits history log information after entering the conference X halfway is not necessarily required. Furthermore, the method disclosed in the present invention can also be applied to a case where a contributor who has participated in a conference temporarily leaves and then enters the same conference halfway. Furthermore, when the conferee (user A) of the conference X performs additional convocation after the start of the conference, the conference management server 1 stores the additional contributor as an additional contributor in the conference management table 102, so that the additional convenor It is possible to manage entry into the conference X on the way.
