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

1-12. -12. (canceled)

13. A network system in which a router and a terminal apparatus are connected in a wireless manner, wherein

one identifier is recorded, a removable recording medium is provided,

said recording medium is loaded into said router and, thereafter, attached to the terminal apparatus, and

said router reads out said identifier, thereby allowing a link between the router and the terminal apparatus specified by said identifier to be established.

14. A network system according to claim 13, wherein

the identifier has previously been written onto said recording medium on a connecting apparatus side.

15. A network system according to claim 13, wherein

a point that said recording medium has been attached to said terminal apparatus is used as a condition for establishment of the link.

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

one identifier is recorded, a removable recording medium is detachably provided,

said identifier is read out from said loaded recording medium, and

a link with the terminal apparatus which is specified by said identifier is established.

17. A router according to claim 16, wherein

the identifier has previously been written onto said recording medium on a connecting apparatus side.

18. A router according to claim 16, wherein

a point that said recording medium has been attached to said terminal apparatus is used as a condition for establishment of the link.

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

one identifier is recorded, a removable recording medium is detachably provided,

said identifier is read out from said loaded recording medium, and

a link is established by said identifier at the time of wireless communication.

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

a step wherein one identifier is recorded and a removable recording medium is provided;

a step wherein said recording medium is loaded into said router and said router reads out said identifier;

a step wherein said recording medium is attached to said terminal apparatus and said terminal apparatus reads out said identifier; and

a step wherein said router detects that said terminal apparatus is specified by said identifier, thereby establishing a link between said router and said terminal apparatus.

21. A program for a network system in which a router and a terminal apparatus are connected in a wireless manner, one identifier is recorded, and a removable recording medium is provided, wherein

said program allows said network system to execute:

a step wherein said recording medium is loaded into said router and said router reads out said identifier;

a step wherein said recording medium is attached to said terminal apparatus and said terminal apparatus reads out said identifier; and

a step wherein said router detects that said terminal apparatus is specified by said identifier, thereby establishing a link between said router and said terminal apparatus.

22. A recording medium on which a program for a network system in which a router and a terminal apparatus are connected in a wireless manner, one identifier is recorded, and a removable recording medium is provided has been recorded, wherein

said program allows said network system to execute:

a step wherein said recording medium is loaded into said router and said router reads out said identifier;

a step wherein said recording medium is attached to said terminal apparatus and said terminal apparatus reads out said identifier; and

a step wherein said router detects that said terminal apparatus is specified by said identifier, thereby establishing a link between said router and said terminal apparatus.
