Abstract

A communication control apparatus having a server apparatus and able to simplify procedures and operations to attend party communication, wherein the server apparatus 103 receives information designating terminal apparatuses 1052 to 1054 and a request seeking that the designated communication apparatuses attend the multipoint communication via a communication circuit, outputs inquiries PAI if the designated terminals intend to attend the multipoint communication via the communication circuit, and when receiving an answer PAA from the designated terminal apparatuses that they will attend said multipoint communication, controls the multipoint communication among a plurality of the terminal apparatuses including the designated communication apparatuses.

Description

technical field [0001] The present invention relates to a communication control device and its method, a communication device, a communication system and its method, and their providing media used in multipoint communication via a communication line. Background technique [0002] In recent years, due to the advancement of communication and computer technology, users do not need to purchase large-scale and expensive systems such as TV conferencing systems. By connecting cameras and microphones to their personal computers at home, real-time transmission of motion between multiple personal computers via the network Images and sounds can realize multi-point communication (パ-ティ communication, party communication) between multiple users. [0003] In the multipoint communication system that performs such multipoint communication, for example, as shown in FIG. 1 , send a party communication request to the server device 2, obtain the ID of the party communic...

AI Technical Summary

Problems solved by technology

[0007] The first problem is that the organizer of the party communication needs to invite other users to participate in the party communication by e-mail or telephone, and notify the ID and password of the party communication, which is very troublesome

[0008] The second problem is that in the above-mentioned conventional multipoint communication system, users who know the party communication ID and password can participate in party communication unconditionally, and security cannot be sufficiently ensured.

[0009] The 3rd problem is, in the above-mentioned existing multipoint communication system, the user who is invited by the sponsor to participate in the party communication needs to operate the operation keys etc. to the terminal device 5 when participating in the party communication. 2 、5 3 It is very troublesome to enter the party communication ID and password known in advance from the sponsor to access the server device 2

[0010] The fourth problem is that it is not possible to notify interested users in real time of information about dynamic changes, dynamic appearances, and disappearances such as the holding and content of party communications using communication lines.

[0011] The fifth issue is that when some means are used to monitor information such as the content of party communication and use it as an information provision means, information that users do not want to be monitored in order to protect privacy cannot be intentionally prevented from being monitored.

[0012] The sixth problem is that when the participants of the party communication and the sponsor are different, it is impossible to control the key information notified to the login user not on the party communication participant side but on the sponsor side

[0013] The seventh problem is that, in the case of notifying party information to non-participants of party communication, it is impossible not to be notified to party participants or users not desired by the party organizer
