Abstract:
1. A multi-point communication system, comprising a communication service unit for providing a type of multi-point communication service or a plurality of types of multi-point communication services for a single communication terminal or a plurality of communication terminals, characterized in that the multi-point communication system further comprises a service receiving unit for receiving a request of one type of multi-point communication service from the single communication terminal or the communication terminals, issuing both a service identifier corresponding to the type of multi-point communication service and a password corresponding to a communication terminal group receiving the type of multi-point communication service to the single communication terminal or each of the communication terminals requesting the type of multi-point communication service, and outputting the service identifier and the password or the passwords to the communication service unit, wherein the service receiving unit receives a request of a type of multi-point communication service from an arbitrary communication terminal denoting the single communication terminal or selected from among the communication terminals, the communication service unit receives the service identifier indicating the type of multi-point communication service and the password of the arbitrary communication terminal from the arbitrary communication terminal, the communication service unit confirms whether or not the password received from the arbitrary communication terminal agrees with the password of the arbitrary communication terminal output from the service receiving unit, and the communication service unit provides the type of multi-point communication service indicated by the service identifier for the arbitrary communication in a case where the password received from the arbitrary communication terminal agrees with the password output from the service receiving unit.
