Abstract

MTID of a terminal apparatus is preliminarily registered into a database of an ISP. In step S2, when a power source of the terminal apparatus is turned on first, (MTID=B) is transmitted from the terminal apparatus to a router. A transmission signal is received by the router and (HGWID=A, MTID=B) is transmitted from the router to the ISP. If (HGWID=A, MTID=B) has been registered in the database, the ISP transmits a permission message in step S5. In step S6, an IP address for a new terminal apparatus is allocated and the new terminal apparatus can participate in a homenetwork. If (HGWID=A, MTID=B) is not registered, a refusal message is sent to the router.
