Abstract
The present invention provides a path setting method for automatically setting network paths. The path setting method for generating paths in a network including a plurality of relay stations and a parent station which are connected with each other through a transmission line, comprises the steps of allowing each of the parent station and the plurality of relay stations to transmit basic information including its own identifier and its own path setting status, by means of a repetitive broadcast, allowing the relay station receiving the basic information to recognize the parent station or another relay station having a temporary path set thereto and transmit its own receiving-environment table including a transmission quality on the transmission line to the recognized station, allowing the another relay station receiving the receiving-environment table to forward it to the parent station through the use of the temporary path so as to notify the receiving-environment table to the parent station, and allowing the parent station receiving the forwarded receiving-environment table to set a temporary path to the relay station which has transmitted the receiving-environment table. In this manner, the parent station collects the transmission qualities on the inter-station transmission lines stepwise in order of the closest relay station to the farthest relay station to automatically set the paths.
