PROBLEM TO BE SOLVED: To provide a mobile multi-point communication system where connected terminals used peer-to-peer for conducting communication. SOLUTION: When a mobile terminal A makes a call connection request to a fixed terminal B capable of containing a plurality of channels, a connection is set up via one channel between a fixed terminal B and the mobile terminal A. Then a mobile terminal C makes a call connection request to the fixed terminal B, and in this case, the connection uses a channel different from the channel used by the mobile terminal A. When the fixed terminal B sets up a connection to the mobile terminal C, the fixed terminal B outputs an information exchange temporary interruption instruction to the mobile terminal A. Thus, the mobile terminal A is at a standby, while keeping a communication session. Then, the connection between the fixed terminal B and the mobile terminal C is set up. Selecting the mobile terminal A or C for a sender in place of the fixed terminal B can transmit the information acquired by the mobile terminal A or C to the fixed terminal B or other mobile terminal. |
