To efficiently manage the communication quality of each path in a mesh network.

In this radio communication system in which radio communication equipment relay to each other to communicate with radio communication equipment existing beyond the range of radio communication, the path states of paths are classified into three states of an invalid state 511, a pavement state 521 and a dirt state 522 so as to be managed. When the path state is the invalid state 511, the path is treated as an invalid path. When the path state is the pavement state 521 or the dirt state 522, the path is treated as a valid path. Even when the quality of the path whose path state is the pavement state 521 is deteriorated, the pavement state is not immediately shifted to the invalid state 511, but shifted to the dirt state 522. In this dirt state 522, a new path is retrieved in parallel. The radio communication equipment of the transmission origin is notified of the path state by using a chance of data transfer.
