Abstract
When a connection request is sent from a telephone terminal, even if it is difficult to set a communication path to the destination telephone terminal only through the packet network, a circuit switching network is also used in cooperation with the packet network in order to set a communication path therethrough, so that call loss is prevented from occurring.
