Abstract

A portable communication terminal apparatus which is connected to a router through a cable includes a storage which stores a plurality of allocated Internet Protocol (IP) addresses, a detector which detects information on the cable connected to the router, and an address setting part which sets one of the plurality of IP addresses as a network IP address based on the detected information on the cable.

Claims

1. A portable communication terminal apparatus which is connected to a router through a cable in a communication system, the apparatus comprising:

a storage which stores a plurality of allocated Internet Protocol (IP) addresses;

a detector which detects information on the cable connected to the router; and

an address setting part which sets one of the plurality of IP addresses as a network IP address based on the detected information on the cable.

2. The portable communication terminal apparatus of claim 1, wherein the detector detects identifying information attached to the cable as the information on the cable.

3. The portable communication terminal apparatus of claim 2, wherein the detector comprises a Radio Frequency Identification reader which is capable of reading an attached wireless IC tag as the identifying information.

4. The portable communication terminal apparatus of claim 1, the detector measures a length of the cable as the information on the cable.

5. The portable communication terminal apparatus of claim 1, wherein the detector detects a Media Access Control address of the router as the information on the cable.

6. The portable communication terminal apparatus of claim 1, wherein the detector detects whether the cable is connected to the router.

7. The portable communication terminal apparatus of claim 6, wherein the storage stores a table comprising the information on the cable and the Internet Protocol address corresponding to the cable.

8. The portable communication terminal apparatus of claim 7, wherein the table in the storage further comprises a router address, the apparatus further comprising a router address processor which processes whether the connected router address is identical to one of the stored router addresses if the cable is connected between the router and the portable communication terminal apparatus.

9. The portable communication terminal apparatus of claim 8, wherein the address setting part sets the network IP address corresponding to the information on the detected cable, if the connected router address is identical to one of the stored router addresses and the detected information on the cable is stored.

10. The portable communication terminal apparatus of claim 8, wherein the address setting part outputs a setting screen to receive a new IP address if the connected router address is not identical at least one of the stored router addresses.

11. A communication system which connects a router and a portable communication terminal apparatus through a cable, wherein the portable communication terminal apparatus comprises:

a storage which stores a plurality of allocated Internet Protocol (IP) addresses;

a detector which detects information on the cable connected to the router; and

an address setting part which sets one of the plurality of IP addresses as a network IP address based on the detected information on the cable.

12. A network address setting method of a portable communication terminal apparatus connected to a router through a cable, the method comprising:

storing a plurality of allocated Internet Protocol (IP) addresses;

detecting information on the cable connected to the router; and

setting one of the plurality of IP addresses as a network IP address based on the detected information on the cable.

13. The network address setting method of claim 12, wherein the detecting comprises detecting identifying information attached to the cable as the information on the cable.

14. The network address setting method of claim 12, wherein the detecting comprises measuring a length of the cable as the information on the cable.

15. The network address setting method of the portable communication terminal apparatus according to claim 12, wherein the detecting comprises a Media Access Control address of the router as the information on the cable.

16. The network address setting method of claim 12, wherein the detecting comprises detecting whether the cable is connected between the router and the portable communication terminal apparatus.

17. The network address setting method of claim 16, wherein the storing comprises storing a table comprising the information on the cable and the IP address corresponding to the cable.

18. The network address setting method of claim 17, wherein the storing further comprises storing a router address, and further comprising processing whether the connected router address is identical to one of the stored router addresses if the cable is connected to the router.

19. The network address setting method of claim 18, wherein the setting as the network IP address comprises setting the network IP address corresponding to the information on the detected cable if the connected router address is identical to one of the stored router addresses and the detected information of the cable is stored.

20. The network address setting method of claim 18, wherein the setting as the network IP address comprises outputting a setting screen to receive a new IP address if the connected router address is not identical to at least one of the stored router addresses.

21. A network address setting method of a communication system comprising a router and a portable communication terminal apparatus, the method comprising:

storing a plurality of allocated Internet Protocol (IP) addresses in the portable communication terminal apparatus;

connecting the router and the portable communication terminal apparatus by the cable; and

detecting information on the cable connected to the router, and setting one of the plurality of IP addresses as a network IP address based on the detected information on the cable.

22. A portable communication terminal apparatus usable with a communication system, the apparatus comprising:

a detector which detects information on an external cable; and

a controller which sets a network IP address according to the detected information on the cable and a plurality of reference allocated Internet Protocol addresses.

23. The portable communication terminal apparatus of claim 22, further comprising:

a housing to accommodate the detector and the controller; and

an adapter disposed on the housing to be connected to the external cable to read the information on the external cable.

24. The portable communication terminal apparatus of claim 23, further comprising:

a user interface unit disposed in the housing and having a display and a user input part to display a screen and to input data using the displayed screen to correspond to at least one of the plurality of reference allocated Internet Protocol addresses.

25. The portable communication terminal apparatus of claim 22, wherein:

the external cable is connectable to one of a first router and a second router; and

the detector detects the information on a first router address when the external cable is connected to the first router, and detects the information on a second router address when the external cable is connected to the second router.

26. The portable communication terminal apparatus of claim 22, wherein the controller sets a new network IP address as the network IP address when the detected information on the cable does not match at least one of the plurality of reference allocated Internet Protocol addresses.
