<p>PROBLEM TO BE SOLVED: To smoothly conduct communication between a terminal connected to a remote segment and a terminal moving among plural segments by exchanging information between the remote segment and the terminal and informing a terminal of its own segment of the obtained terminal information. SOLUTION: A communication controller 1a sets a communication line with a communication controller 1b of a 2nd segment and a communication line with a communication controller 1c of a 3rd segment. Then the communication controller 1a receives terminal identification information, including a terminal identifier informed by terminals 11-13 and address information of the terminals respectively. Similarly, when the communication controller 1a receives the terminal identification information of terminals 21, 22 from the communication controller 1b and the terminal identification information of terminals 31, 32 from the communication controller 1c, the communication controller 1a informs each terminal resident in a 1st segment of the information. Thus, the terminals 11-13 resident in the 1st segment acquire the terminal identification information of the terminals 21, 22, 31, 32 in the other segments.</p> |
