CIRCUIT-SWITCHED NETWORK

摘要

A local switch serving a terminal constituting the destination of an IP packet is identified from the IP address of the packet, and time slot switching information is formed, this being information relating to a route through an STM network to this local switch. The packet can then be transferred through the STM network in accordance with this time slot switching information. As a result, a packet with an IP address can be transferred through an STM network.
