Apparatus, system, and method of controlling connection among terminals and recording medium storing connection control program

摘要

When a request for participating in a session being performed by a plurality of participating terminals is received from a terminal that is not participated in the session, a system extracts identification information of one or more candidate terminals that are associated with the participating terminal for each one of the plurality of participating terminals, and determines whether identification information of the terminal that sends the request is included in the extracted candidate terminal identification information to generate a determination result. The determination result is used to determine whether to allow the terminal that sends the request to connect with the plurality of participating terminals to participate in the session.

主权项

1. A connection control system, which controls connection of at least two transmission terminals of a plurality of transmission terminals, comprising:
a memory which stores information including a plurality of request terminal identification information, and for each of the request terminal identification information stores one or more corresponding counterpart terminal identification information; a terminal manager configured to manage contents of the memory, for each of the transmission terminals, the request terminal identification information which identifies one or more counterpart corresponding transmission terminals to be a candidate destination of contents data transmitted from each of the transmission terminals; a receiver configured to receive a participation request from a third transmission terminal of the plurality of transmission terminals that is not participating in a session, when the session is established to transmit contents data between a first transmission terminal and a second transmission terminal of the plurality of transmission terminals; a determiner configured to determine whether terminal identification information for identifying the third transmission terminal is included in any one of the corresponding counterpart terminal identification information for identifying a candidate counterpart transmission terminal for the first transmission terminal that is currently participating in the session being established, using identification information of the first transmission terminal as the request terminal identification information which is utilized to access the corresponding counterpart terminal identification information stored in the memory, or the corresponding counterpart terminal identification information for identifying a candidate counterpart transmission terminal for the second transmission terminal that is currently participating in the session being established, using identification information of the second transmission terminal as the request terminal identification information which is utilized to access the corresponding counterpart terminal identification information stored in the memory, of the terminal identification information being managed by the terminal manager, wherein the determiner executes control to allow the third transmission terminal to participate in the session being established, when the determiner determines that the terminal identification information for identifying the third transmission terminal is included.
