<P>PROBLEM TO BE SOLVED: To allow simultaneous connection by the same user using a plurality of communication terminals. <P>SOLUTION: In the communication system, communication among a first communication terminal, a second communication terminal, and a third communication terminal can be made through a switching device. The first communication terminal comprises an authentication part which authenticates the second communication terminal using a communication protocol between the communication terminals within a predetermined distance and acquires terminal identification information of the second communication terminal; and a transmission part which transmits the terminal identification information of the first communication terminal, the terminal identification information of the second communication terminal, and an authentication result to the switching device in the case of connection with the third communication terminal. The switching device comprises a terminal identification information holding part which holds the terminal identification information of the first communication terminal received from the first communication terminal and the terminal identification information of the second communication terminal, based on the authentication result; and a determination part which determines whether or not communication between the second communication terminal and the third communication terminal can be made, based on the information held in the terminal identification information holding part. <P>COPYRIGHT: (C)2012,JPO&INPIT |
