Abstract
An inter-network routing control method for selecting the optimum gate station in a packet network connected to another network via a plurality of gate stations. A representative gate station can be specified for each addressed network. Upon an inter-network switching call request, the switch station transfers the call request to a representative gate station, and the representative gate station decides the optimum gate station. It is possible to lighten the load on the switch station at the time of inter-network switching communication and facilitates changing the configuration of gate stations in the packet network.
