Abstract

When carrying out a downlink handover, a source base transceiver station from which a mobile node is moving receives packets to be transmitted, via a wireless section, to the mobile node from an IP network, and copies and transfers them to a destination base transceiver station to which the mobile node is moving. On the other hand, when carrying out an uplink handover, the source base transceiver station compares the reliability of transport blocks which are received via a wireless section, from the mobile node and which are demodulated and decoded by the local station with that of transport blocks which are received via an IP network, from another base transceiver station and which are demodulated and decoded thereby, packetizes selected transport blocks with a better quality, and transmits them to a communications-partner node according to a route table, thereby implementing distribution of traffic via the IP network.
