DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conference type communication system in which a plurality of persons geographically dispersed mutually exchange the same information online. Video teleconferences, in which conference information is exchanged between multiple locations using a video terminal or telephone, and conference telephones, in which telephones are used to hold conferences between three or more locations, are performed using conventional telephone networks. However, with the advancement of ISDN and networks, video conferences and conference-type telephones, which were conventionally expensive, have rapidly become widespread.

FIG. 6 shows a system configuration diagram of a conference data communication system using a network. In the figure, 21 is a network, 22 is a conference terminal A, 23 is a conference terminal B, 24 is a conference terminal C, and 25 is a conference terminal D. Conference terminal A22, B
23, C24 and D25 are each composed of a TV terminal, a FAX, a personal computer terminal, a telephone, and the like. Text has been displayed on other personal computer terminals by input, and conference information has been exchanged with each other via the network 21.

2. Description of the Related Art In current facsimile communication and message communication, a destination list that can be used only by a calling user is designated, and information transferred by the calling party is transferred to all destinations registered in the destination list. A service (broadcasting service) has been realized.

That is, in the system configuration diagram of FIG. 6, a conference terminal A22 is a calling terminal, and conference terminals B23, C24, and D25.
Is the receiving terminal, the transmitting station constituting the network 21 has a destination list (B, C, D), and performs unilateral broadcast communication from the transmitting side to the receiving side, and the receiving side performs a conference simultaneously or sequentially. Receive information. Similarly, when another conference terminal is the transmitting terminal, the transmitting terminals B, C, and D respectively transmit the destination lists (A, C, D), (A, B, D), and (B, C, D). And unilaterally broadcast from the calling party to the called party. In this case, when information is transmitted from the transmitting side to another receiving side, information cannot be transmitted from the other receiving side to the transmitting side, so-called two-way communication cannot be performed.

[0005]

However, the prior art has the following two problems. That is, (1) Since the destination list is owned for the caller, when using it for conference communication or the like, the attendees must individually register or change the destination list, which is troublesome. (2) Only one-way communication is possible because we have a destination list for the caller. When the user who has received the information transfers the information, it is necessary to transmit the information again, which is convenient.

An object of the present invention is to provide means for allowing a plurality of users to have a destination list in common and enabling reception and transmission of information without disconnecting a communication path.

FIG. 1 is a block diagram showing the principle of the present invention. In the figure, 1 is a conference type communication processing node, 2
Is a group list for storing a group-specific destination list and information specifying a storage area for information, 3 is a destination list for storing network accommodating position information of users constituting the group corresponding to the group, and 4 is a conference user's transfer. Information storage device for temporarily storing the selected information, 5 is a means for newly registering a destination list corresponding to the group, 6 is a means for referring to and changing the destination list corresponding to the group identification number designated by the user, 7 is use A, 8 are user B, 9 is user C,
10 indicates a public network.

A plurality of users 7, 8, and 9 form one group by the conference-type communication processing node 1 via the public network 10, and any user can perform two-way communication with a plurality of other users. Configure to do so. Group members can share the destination list, register and change one destination list in the group, and share the destination list so that conference communication independent of the caller can be performed. .

[0009]

FIG. 2 is a processing sequence diagram of the present invention. In the figure, user A makes a request for registration of conference communication, and users B and C
5 shows a sequence in which broadcast communication is performed and transfer information is simultaneously transmitted from the subscriber C to the subscribers A and B. . The user A makes a registration request for the group member accommodation position, captures the group number of the group list 2,
The destination list 3 corresponding to the group number is created, and the information storage area of the information storage device 4 is captured. . When the registration in the processing node 1 is completed, the subscriber A
, A registration completion signal (group number + user A identification number) is returned. . User A issues a call request (group number + user A identification number) to the processing node 1 for conference communication,
Select the destination list 3 from the group number and set the destination list 3
To all destinations except the caller. . An incoming call instruction (group number + user B identification number) is transmitted from the processing node 1 to the user B, and the user B receives the information from the user A. . The processing node 1 also sends an incoming call instruction (group number + user C identification number) to user C, and user C receives the information from user A. . The processing node 1 transmits a completion notification of the incoming instruction to the user A. . A transfer request (group number + user C identification number + transfer information) for transmitting the transfer information from user C is transmitted to processing node 1, and the group number + user C
The received information is stored in the information storage area specified by the identification number, and the received information is transferred from the destination list 3 to all destinations except the information transferer C. . The transfer information (group number + user C identification number + transfer information) is transmitted from the processing unit 1 to the user A, and at the same time, the transfer information (group number + user C identification number) is also sent to the user B. + Transfer information) is transmitted. . When the transfer information is transmitted from the user B to the other users A and C, the transfer can be performed by the same processing as described above, and the bidirectional communication can be performed by adding the identification number of each user. Become.
