<p><P>PROBLEM TO BE SOLVED: To make it possible to suppress the reduction of communication quality, even when a packet loss is suddenly caused in a packet transmission route in an FWA device having mesh constitution. <P>SOLUTION: The FWA device 1 converts packets of information desired to be transmitted into error correction codes, selects a plurality of transmission routes having no pass overlap from a previously stored transmission route list, calculates the allocation distribution of packets to the selected transmission routes, divides the packets in accordance with the calculated packet allocation distribution, adds transmission route information of divided packets, the common ID number of the divided packets and an assembly order number to each of the divided packets, and transmits the divided packets to each transmission route on the basis of the transmission route information added to each divided packets. When receiving the divided packets, the FWA device 1 assembles the divided packets having the same ID number out of the received divided packets on the basis of the assembly order number and decodes the packets by using the error correction codes. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
