    It is possible to realize a packet transfer having a high failure-resistance capable of eliminating concentration of a load to a part of a network while autonomously maintaining an optimal route without mounting a function of route control on a radio terminal. In a packet transfer system including a plurality of radio base stations and at least one radio terminal, each of the radio base stations includes a location table for correlating the radio base station to a radio terminal belonging to the radio base station. By exchanging the information in the location table between the radio base stations, each of the radio base stations judges the location of the radio terminal in the network. Each of the radio base stations updates its location table by the exchanged table information and transmits the received packet to the next radio base station to serve as a relay node to the radio terminal of the destination. Moreover, when performing route search, in addition to the network radio environment, the packet payload is considered so as to optimize the packet transfer route.
