<P>PROBLEM TO BE SOLVED: To provide a packet transfer method and the like in an ad-hoc network where signaling that becomes overhead in path set-up is not required, even when a large amount of mobile terminals and one radio base station communicate with each other. <P>SOLUTION: An inquiry packet in a downlink direction from a radio base station is received. A first TTL value, set to the inquiry packet, is stored thereafter. The inquiry packet subtracting 1 from the first TTL value is then transmitted. Next, a reply packet in the uplink direction to the radio base station is received. Only when a second TTL value set to the reply packet is smaller than the first TTL value stored according to the reply packet, a reply packet to which the first TTL value has been set, is transmitted. The TTL value may also be the number of hops. <P>COPYRIGHT: (C)2007,JPO&INPIT |
