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. |
