摘要： PROBLEM TO BE SOLVED: To alleviate a burden of inputting a terminal ID of a terminal to be subscribed in a network by power line communication.SOLUTION: A server transmits a trigger signal facilitating subscription to a network to a terminal physically connected to the network, by broadcasting. The terminal, when receiving the trigger signal from the server, refers a status representing whether or not the terminal has been already subscribed in the network, and in a case where the terminal has not been subscribed, replies with a response signal including an ID of the terminal at one reply timing selected at random from a plurality of reply timings from when the trigger signal is received that are preliminarily set. The server, upon receipt of the response signal from the terminal, registers the terminal as a terminal subscribed in the network, and transmits to the terminal notification indicating that the terminal has been subscribed in the network. The terminal, upon receipt of the notification indicating that the terminal has been subscribed in the network from the server, sets the status to one representing that the terminal has been subscribed in the network.
