Title:
WIRELESS TERMINAL APPARATUS, WIRELESS COMMUNICATION SYSTEM, AND PACKET ROUTING METHOD
Document Type and Number:
WIPO Patent Application WO/2005/081470
Kind Code:
A1
Abstract:
A wireless terminal apparatus capable of reorganizing, in a short time, a route where a communication breakdown has occurred. When any communication breakdown has occurred between relay terminals (501-4,501-7) that relay communication between a transmitting terminal (501-1) and a destination terminal (501-10), each of the relay terminals determines whether it is located on the transmitting terminal side or the destination terminal side relative to the communication breakdown. Then, the relay terminal (501-4) generates a route reorganization control signal (CD1) addressed to the destination terminal, while the relay terminal (501-7) generates a route reorganization control signal (CD2) addressed to the transmitting terminal. The route reorganization control signals (CD1,CD2) are transmitted by broadcast such that the route reorganization control signal (CD1) sequentially reaches a relay terminal (501-5) and a relay terminal (501-6), while the route reorganization control signal (CD2) sequentially reaches a relay terminal (501-8) and the relay terminal (501-6). The relay terminal (501-6) determines that the route reorganization control signals (CD1,CD2) correspond to each other, then generates route reorganization response control signals (CD3,CD4), and transmits them, by unicast, to the relay terminals (501-5,501-8).
