To provide a method of constructing a communication route where traffics required for constructing the communication route can be made relatively small and where a relatively small amount of data concerning the communication routes is required to be stored at terminals.
The communication route constructing method of this invention comprises a step S2 of enabling a terminal to transmit an H packet, in a network that performs power line carrier communication, which contains communication quality information indicating the quality of communication kept through a communication route with its host terminal, to the communication network with a broadcast communication, steps S4, S7 and S10 of making an H packet receiving terminal acquire the quality of communication from the H packet sending terminal to the terminal itself and also acquire the quality of communication from the terminal itself to the sending terminal of a notice communication packet, and steps S13 and S14 of calculating the quality of communication with the host terminal on the basis of the two-way communication quality acquired by the H packet receiving terminal through the steps S4, S7, and S10 and the communication quality information contained in the received H packet and of constructing a communication route with the host terminal only when the calculated communication quality meets the prescribed requirements.
