<p>PURPOSE:To reduce the loads of connecting a switch and deciding the passage of a channel by holding the passage and the capacity, etc., of a virtual channel inside a network at the time of completing a call and responding to the call for a second time by using them. CONSTITUTION:At the time of completing a call, at an ATM switchboard 100, call setting passage data 113 such as the passage and the capacity, etc., of the virtual channel are held through a processor 108 inside the network and also corresponding call connection data for the connection of a switch 107 are held. Then, When communication is performed again using the same virtual channel through a control signal reception part 111, the call is originated using the data 113 and 114 through the processor 108 and the decision of the channel and the connection of the switch are performed under the reduced loads. Also, it is the same even when the data 113 or the like are concentrated to the plural switchboards to be held without making the respective switchboards hold them.</p> |
