PURPOSE:To attain the high speed of the change of a communication band even at the time of a connection type communication by allowing a transmission band setting part to operate independently of a calling control part and a route setting part. CONSTITUTION:A calling control part 114 request the setting of a communication route and the ensure of a transmission band to a connection control part 108. The connection control part 108 request the setting of a communication route between terminals to a route setting part 106. Then, when a terminal 105 opens an animation window, and receives animation information from a terminal 102, the information of the opening of the window is transmitted to a transmission band setting part 107 in the connection control part 108, and the communication band of a communication channel 110 is set 0Mbps. And also, when the terminal 105 closes the animation window, and the transmission of the information from the terminal 102 is not necessary, the information of the closure of the window is transmitted to the transmission band setting part 107, and the communication band of the communication channel 110 is 0Mbps. At that time, the transmission band setting part 107 operates independently of the calling part 114 and the route setting part 106. |
