SESSION CONTROL SYSTEM, COMMUNICATION SYSTEM, SESSION CONTROL METHOD, AND RECORDING MEDIUM STORING SESSION CONTROL PROGRAM

摘要

A session control system stores, in a memory, limitation information for each one of a plurality of first sessions where participatable terminals that can participate in the session are limited. The limitation information includes: participatable terminal identification information for identifying each one of participatable terminals allowed to participate in the first session; and participant terminal identification information for identifying each one of the participatable terminals that is participating in the first session. In response to receiving a request for starting a second session with a counterpart terminal by a first terminal, the session control system determines whether the counterpart terminal is participating in any one of the first sessions using the participant terminal identification information, and accepts the request to enable the first terminal to start the second session, when the counterpart terminal is not participating in any one of the first sessions.

1. A session control system comprising:
a memory configured to store limitation information for each one of a plurality of first sessions where participatable communication terminals that can participate in the session are limited, the limitation information including:
participatable terminal identification information for identifying each one of participatable communication terminals allowed to participate in the first session; andparticipant terminal identification information for identifying each one of the participatable communication terminals that is participating in the first session; a receiver configured to receive a request for starting a second session with a counterpart communication terminal by a first communication terminal; and a processing circuitry configured to
determine whether the counterpart communication terminal is participating in any one of the first sessions using the participant terminal identification information, andaccept the request to enable the first communication terminal to start the second session with the counterpart communication terminal, when the counterpart communication terminal is not participating in any one of the first sessions.
