MTID of a terminal apparatus is preliminarily registered into a database of an ISP. In step S, 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 S. In step S, 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.

Network system

A service providing system is provided which enables the users of an information transmission service in which information is sent and received in real time over a network to recognize their respective environment and conditions for provision of their own information. The service providing system () includes a service provider () including a communication server (), a Web server () and a DB server () and a plurality of communication terminals () connected to the service provider () via the network, and it provides an information transmission service in which information is provided from one of communication devices to the other, or vice versa, in real time. The communication terminal () at the information provider first registers explanatory information, such as content, offering price, etc. of offered information to be provided into the DB server (), and updates the information registered in the DB server () to a log-in status when the information provider has become able to provide the information in real time; and the Web server () updates the Web page at each time so that the explanatory information having thus been in the log-in status will be included in choices.
