Abstract
A base-station host system achieves high-speed routing to reduce a burden on a controller which carries out a routing process, and receives a cell containing a plurality of packets (an ATM cell of AAL Type 2) from a base station. A cell containing a plurality of packets is transmitted from the base station to the base-station host system. A packet extracting unit extracts the packets from the received cell. A cell generating unit generates an internally processable cell based on information carried by the payload of a packet. A switch unit switches internally processable cells depending on routes thereof. For reverse communications, internally processable cells are sent from the switch unit to a packet generating unit. The packet generating unit generates packets based on information carried by the payloads of the internally processable cells. A cell transmitting unit collects a plurality of packets designed for the same base station, generates a cell containing those packets, and transmits the generated cell to the base station.
