An address setting method of a wireless communication system 1 includes the steps of generating an address by each of a HEMS controller 5 and a HEMS terminal 7 based on an address prefix included in a router advertisement of a smart meter 3, and setting, by the HEMS terminal 7, a route of a packet sent to a HEMS server 13 to a route by way of the HEMS controller 5. The HEMS controller 5 performs NAT setting by replacing an address prefix of a source address of the packet sent to the HEMS server 13 with an address prefix of the HEMS controller 5. |
