Abstract

A system and method provides location sensitive Web content in response to receiving location based Web content requests. Location information derived from multiple sources by a mobile terminal is included in a Web content request. Location tagged Web content is then retrieved via a Web server/search engine and filtered in accordance with the location/keyword information provided in the content request.

obtaining a location update relative to a position of a mobile terminal;

forming location criteria from the location update;

including the location criteria in a Web content request from the mobile terminal;

filtering results from the Web content request according to the location criteria to form the position relevant Web content; and

providing the position relevant Web content to the mobile terminal.

2. The method according to claim 1, wherein obtaining the location update comprises receiving location information from a base station wirelessly coupled to the mobile terminal.

3. The method according to claim 1, wherein obtaining the location update comprises receiving location information from a Global Positioning System (GPS).

4. The method according to claim 1, wherein obtaining the location update comprises:

receiving map data associated with a first position of the mobile terminal;

projecting the map data onto a display of the mobile terminal;

indicating a second position of the mobile terminal on the projected map data; and

using the second position as the location update.

5. The method according to claim 1, wherein forming location criteria comprises establishing a location accuracy parameter that defines an area surrounding the location update.

6. The method according to claim 1, wherein the Web content request includes a HyperText Transport Protocol (HTTP) message.

7. The method according to claim 6, wherein the HTTP message presents the location criteria within an HTTP header.

8. The method according to claim 1, wherein the filtering further includes filtering the results from the Web content request according to a search keyword.

9. The method according to claim 8, wherein the providing further includes providing the position relevant Web content that relates to the search keyword.

10. The method according to claim 9, further comprising storing the position relevant Web content in a location bookmark area of the mobile terminal.

11. The method according to claim 10, further comprising periodically updating the position relevant Web content.

12. The method according to claim 11, further comprising categorizing the updated results according to a location heading.

13. The method according to claim 12, wherein the categorized headings are prioritized according to the relative position of the mobile terminal.

14. The method according to claim 11, further comprising automatically displaying the updated results in response to the relative position of the mobile terminal.

15. A geographically based Web content system, comprising:

a mobile terminal geographically located within the Web content system;

a Web server adapted to receive Web content requests from the mobile terminal; and

a search engine coupled to the Web server and adapted to gather location tagged Web content in response to the Web content requests, wherein location tags of the Web content gathered conform to geographical criteria expressed by the mobile terminal in the Web content requests.

16. The geographically based Web content system according to claim 15, wherein the mobile terminal comprises a location update module adapted to maintain a current location of the mobile terminal.

17. The geographically based Web content system according to claim 16, wherein the location update module comprises a Global Positioning System (GPS) module.

18. The geographically based Web content system according to claim 16, wherein the mobile terminal further comprises a geographical search module coupled to the location update module and adapted to convert the current location of the mobile terminal into the geographical criteria contained within the Web content request.

19. The geographically based Web content system according to claim 18, wherein the Web content request includes a HyperText Transfer Protocol (HTTP) header containing the geographical criteria.

20. The geographically based Web content system according to claim 15, wherein the mobile terminal further comprises a text to speech module adapted to convert textual portions of the Web content received from the Web server into audible information.

21. A mobile terminal capable of being wirelessly coupled to a network which includes location tagged Web content, the mobile terminal comprising:

a memory capable of storing a location update module and a geographical search module;

a processor coupled to the memory and configured by the location update module to maintain position information associated with the mobile terminal and configured by the geographical search module to request the location tagged Web content that relates to the position of the mobile terminal; and

a transceiver configured to receive the location tagged Web content from a Web server.

22. The mobile terminal according to claim 21, further comprising a text to speech module adapted to convert textual portions of the location tagged Web content into audible information.

23. A computer-readable medium having instructions stored thereon which are executable by a mobile terminal for requesting location based Web content by performing steps comprising:

obtaining location updates relative to a position of the mobile terminal;

defining an area of interest surrounding the position of the mobile terminal; and

requesting location based Web content that conforms to the area of interest.

24. A Web server capable of being coupled to a network to facilitate a location based Web content search, the Web server comprising:

means for receiving location based Web content requests containing location criteria associated with a location of a mobile terminal;

means for communicating the location based Web content requests to a search engine;

means for receiving responses from the search engine in response to the location based Web content requests; and

means for filtering the responses to conform to the location criteria.

25. A computer-readable medium having instructions stored thereon which are executable by a Web server by performing steps comprising:

receiving Web content requests containing location criteria associated with a location of a mobile terminal;

communicating the Web content requests to a search engine;

receiving responses from the search engine in response to the Web content requests; and

filtering the responses to conform to the location criteria.
