Abstract

Provided are a method and apparatus for supplying a local service (LS) using a LS information server that is based on a distributed network. The LS may be supplied to the terminal through at least one of an LS information server, a root server, and a neighboring LS information server.

Claims

1. A method for providing a local service (LS), the method comprising:

acquiring position information of a terminal;

requesting an LS information server for LS information about a region in which the terminal is located by inserting the acquired position information of the terminal in a field of a message and transmitting the message to the LS information server;

receiving LS information; and

displaying the LS information received in response to the request.

2. The method of claim 1, wherein the LS information server is a distributed LS information server.

3. The method of claim 1, further comprising:

requesting the LS information server for remote LS information;

displaying the remote LS information received from the LS information server; and

supplying a LS selected from the displayed remote LS information.

4. The method of claim 1, wherein

the LS information server and at least one neighboring LS information server share LS information about a region in which the LS information server is located and the LS information of a region in which the neighboring LS information server is located, and

the neighboring LS information server is located in a region that is adjacent to the region in which the terminal is located.

5. The method of claim 1, wherein the receiving LS information comprises receiving information about a root server from the LS information server, in response to the request for the remote LS information, and the method further comprises:

requesting, based on the received root server information, remote LS information from the root server;

displaying the remote LS information received from the root server; and

supplying a LS selected from the displayed remote LS information.

6. The method of claim 1, wherein the receiving LS information comprises receiving root server information from the LS information server, in response to the request for the remote LS information, and the method further comprises:

requesting the root server for information about a neighboring LS information server that is located in a region that is adjacent to the region in which the terminal is located;

requesting the neighboring LS information server for remote LS information based on the neighboring LS information server information received from the root server;

displaying the remote LS information received from the neighboring LS information server; and

supplying a LS selected from the displayed remote LS information.

7. The method of claim 1, wherein the receiving LS information comprises receiving information about a root server from the LS information server, in response to the request for the remote LS information, and the method further comprises:

requesting the root server for remote LS information based on the received root server information;

receiving information of a neighboring LS information server in response to the requested remote LS information;

requesting the neighboring LS information server for the remote LS information based on the received neighboring LS information server information;

displaying the remote LS information received from the neighboring LS information server; and

supplying a LS selected from the displayed remote LS information.

8. The method of claim 1, wherein, in response to the terminal moving from a region in which the LS information server is located to a neighboring region in which a neighboring LS information server is located, the method further comprises:

requesting the LS information server for LS information about the region in which the terminal is located;

receiving information of the neighboring LS information server that is located in the neighboring region, from the LS information server;

requesting the neighboring LS information server for the LS information about the region in which the terminal is located based on the received neighboring LS information; and

receiving an LS information of the region in which the terminal is located from the neighboring LS information server.

9. The method of claim 1, further comprising displaying the LS information,

wherein the LS information includes at least one of summaries of the LS, a method for connection to the localized wireless network (LWN), a method for connection with the LS server, and use of the LS.

10. The method of claim 1, further comprising requesting a dynamic host configuration protocol (DHCP) server for information about the LS information server,

wherein the requesting of the LS information comprises requesting the LS information about the region in which the terminal is located based on the LS server information received in response to the request.

11. A terminal comprising:

a position information acquisition unit to acquire position information of the terminal;

an information request unit to request a LS information server for information about a region in which the terminal is located, by inserting the acquired terminal position information into a message; and

an information supply unit to supply a LS selected by a user, based on received LS information.

12. The terminal of claim 11, wherein the information request unit requests the LS information server for remote LS information, and

the information supply unit displays the remote LS information received from the LS information server and supplies a LS selected from the displayed remote LS information.

13. The terminal of claim 11, wherein the LS information server and at least one neighboring LS information server share LS information of a region in which the LS information server is located and the LS information of a region in which the neighboring LS information server is located, and

the neighboring LS information server is located in a region that is adjacent to the region in which the terminal is located.

14. The terminal of claim 11, wherein the information supply unit comprises:

an information reception unit to receive information of a root server in response to remote LS information requested from the LS information server, and to receive the remote LS information requested from the root server;

a display unit to display the received remote LS information; and

a connection unit to connect the terminal to the LS selected based on the displayed remote LS information.

15. The terminal of claim 11, wherein the information supply unit comprises:

an information reception unit to receive information of a root server, and to receive information of a neighboring LS information server from the root server; and

a display unit to display the remote LS information received from the neighboring LS information server.

16. The terminal of claim 11, wherein

the information request unit requests the LS information server for LS information of the region in which the terminal is located and requests a second LS information server located in the neighboring region for the LS information about the region in which the terminal is located, and

the information supply unit supplies LS information about the region in which the terminal is located, received from the second LS information server.

17. The terminal of claim 11, further comprising a display unit to display the LS information,

wherein the LS information comprises at least one of summaries of the LS, a method for connection to the LWN, a method for connection with the LS server, and use of the LS.

18. The terminal of claim 11, wherein the information request unit requests a DHCP server for information about the LS information server and requests for the LS information of the region in which the terminal is located based on the LS server information received in response to the request.

19. An LS information server comprising:

an information reception unit to receive position information of a terminal and a request for LS information about a region in which the terminal is located, and to receive a request for remote LS information from the terminal; and

an information supply unit to transmit the requested LS information to the terminal, and to supply at least one of information of a neighboring LS information and the remote LS information.

20. The LS information server of claim 20, wherein the LS information about the region in which the terminal is located is shared with the remote LS information supplied by the neighboring LS information server, and

the LS information server and the neighboring LS information server are distributed servers.

21. The LS information server of claim 20, wherein the information supply unit supplies information of a root server to the terminal, in response to the received request for the remote LS information.
