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.

Claims

1. A network system in which a router and a terminal apparatus are connected in a wireless manner, comprising:

a terminal apparatus;

a router;

a server; and

a removable recording medium,

wherein, when a user intends to connect the terminal apparatus to the router;

an operator of the server issues the removable recording medium to the user, the removable recording medium comprising a first terminal apparatus identifier;

the removable recording medium is loaded into the router, the first terminal apparatus identifier is read out to the router, and the router stores the first terminal apparatus identifier,

the removable recording medium is thereafter attached to the terminal apparatus and the terminal apparatus transmits the first terminal apparatus identifier to the router,

the router receives the first terminal apparatus identifier from the terminal apparatus and determines a correlation with the first terminal apparatus identifier stored in the router,

the router transmits the first terminal apparatus identifier and an identifier associated with the router to the server, and

a wireless link between the router and the terminal apparatus is allowed after confirming that the first terminal apparatus identifier and the identifier associated with the router are associated in a remote database associated with the server.

2. A network system according to claim 1, wherein

the first identifier has previously been written onto the removable recording medium.

3. A network system according to claim 1, wherein the removable recording medium is attached to the terminal apparatus before the wireless link is established.

4. A router for exchanging information between terminal apparatuses connected in a wireless manner, wherein

a removable recording medium comprising a first terminal apparatus identifier is provided,

the removable recording medium is loaded into the router,

the first terminal apparatus identifier is read out from the removable recording medium to the router and stored by the router,

the removable recording medium is thereafter loaded into the terminal apparatus,

the first terminal apparatus identifier is transmitted from the terminal apparatus to the router,

the router determines a correlation between the first terminal apparatus identifier transmitted by the terminal apparatus and the first terminal apparatus identifier stored in the router,

the router transmits the first terminal apparatus identifier and an identifier associated with the router to a remote server, and

a wireless link between the router and the terminal apparatus is established after confirming that the first terminal apparatus identifier and the identifier associated with the router are associated in a database associated with the server.

5. A router according to claim 4, wherein

the first identifier has previously been written onto the recording medium.

6. A router according to claim 4, wherein the removable recording medium is attached to the terminal apparatus before the wireless link is established.

7. A terminal apparatus for exchanging information in a wireless manner, wherein

a first terminal apparatus identifier associated with a terminal apparatus is recorded onto a removable recording medium, the removable recording medium being detachably provided,

the first terminal apparatus identifier is read out from the loaded removable recording medium onto a router and stored by the router,

the first terminal apparatus identifier is read out from the loaded removable recording medium onto the terminal apparatus and transmitted to the router,

the router confirms that the first terminal apparatus identifier stored in the router corresponds to the first terminal apparatus identifier transmitted by the terminal apparatus,

the router transmits the first terminal apparatus identifier and an identifier associated with the router to a remote server, and

a wireless link between the router and the terminal apparatus is established after confirming the first terminal apparatus identifier and the identifier associated with the router are associated in a database associated with the server.

8. A communicating method in a network system in which a router and a terminal apparatus are connected in a wireless manner, comprising:

providing a first terminal apparatus identifier for a terminal apparatus on a removable recording medium prior to connecting the terminal apparatus with a network system;

loading the recording medium into a router;

reading out at the router the first terminal apparatus identifier;

storing the first terminal apparatus identifier in the router;

attaching the recording medium to the terminal apparatus;

reading out at the terminal apparatus the first terminal apparatus identifier;

transmitting the first terminal apparatus identifier from the terminal apparatus to the router;

determining at the router a correlation between the first terminal apparatus identifier transmitted by the terminal apparatus and the first terminal apparatus identifier stored in the router;

transmitting, by the router, the first terminal apparatus identifier and an identifier associated with the router to a remote server; and

establishing a link between the router and the terminal apparatus after confirming that the first terminal apparatus identifier and the identifier associated with the router are associated in a database associated with the remote server.

9. A computer-readable recording medium comprising a program which, when executed by a computer, performs a networking method comprising:

providing a first terminal apparatus identifier associated with a terminal apparatus on a recording medium prior to connection of the terminal apparatus to a wireless system;

reading out, from the recording medium, to the router the first terminal apparatus identifier;

storing the first terminal apparatus identifier in the router;

reading out, from the recording medium, to the terminal apparatus the first terminal apparatus identifier;

transmitting the first terminal apparatus identifier from the terminal apparatus to the router;

determining at the router a correlation between the first terminal apparatus identifier transmitted by the terminal apparatus and the first terminal apparatus identifier stored in the router;

transmitting, by the router, the first terminal apparatus identifier and an identifier associated with the router to a remote server; and

establishing a link between the router and the terminal apparatus after confirming that the first terminal apparatus identifier and the identifier associated with the router are associated in a database associated with the remote server.
