Abstract

A method of operating navigation system having location based services and temporal management comprising selecting a temporal component including a time of interest in a client, a server, or a combination thereof; filtering navigation and location based information with the temporal component by the client, the server, or a combination thereof, for forming time of interest relevant information; and communicating the time of interest relevant information between the client and the server for display by the client.

Claims

1. A method of operating navigation system having location based services and temporal management comprising:

selecting a temporal component for identifying a time of interest for a client, a server, or a combination thereof;

sending a server request based on comparing an elapsed time between a specified cache update time and a last cache update time;

receiving a temporal stamped local content, with a control device, corresponding to the temporal component at the time of the server request;

updating a local content cache based on the temporal stamped local content indicating a cache update time for when the local content cache is updated;

filtering the temporal stamped local content with the temporal component for forming time of interest relevant information; and

communicating the time of interest relevant information for displaying the local content cache by the client.

2. The method as claimed in claim 1 further comprising further filtering the time of interest relevant information for generating a further time of interest relevant information.

3. The method as claimed in claim 1 wherein filtering the temporal stamped local content with the temporal component comprises generating the time of interest relevant information from the temporal stamped local content.

4. The method as claimed in claim 1 wherein communicating the time of interest relevant information comprises storing the time of interest relevant information in the local content cache.

5. The method as claimed in claim 1 wherein communicating the time of interest relevant information comprises information relating to a future time, a past time, or a combination thereof.

6. A method of operating navigation system having location based services and temporal management comprising:

selecting a temporal component for identifying a time of interest for a client, a server, or a combination thereof;

sending a server request based on comparing an elapsed time between a specified cache update time and a last cache update time;

receiving a temporal stamped local content, with a control device, corresponding to the temporal component at the time of the server request;

updating a local content cache based on the temporal stamped local content indicating a cache update time for when the local content cache is updated;

filtering temporal stamped local content with the temporal component for forming time of interest relevant information;

communicating the time of interest relevant information to the client; and

storing the time of interest relevant information in the local content cache for displaying by the client.

7. The method as claimed in claim 6 wherein storing the time of interest relevant information further comprises a further filtering of the time of interest relevant information.

8. The method as claimed in claim 6 wherein selecting a temporal component comprises selecting a future time, a past time, or a combination thereof.

9. The method as claimed in claim 6 wherein filtering the temporal stamped local content comprises filtering to form time of interest relevant information including filtering with a future time, a past time, or a combination thereof.

10. The method as claimed in claim 6 further comprising detecting GPS data information in the server request.

11. A navigation system having location based services and temporal management comprising:

a control device having location based service capability, a local content cache, and a client output means, wherein the control device is for;

sending a server request based on comparing an elapsed time between a specified cache update time and a last cache update time;

receiving a temporal stamped local content corresponding the temporal component at the time of the server request, the temporal component including a time of interest selected in a client, a server, or combination thereof;

updating the local content cache based on the temporal stamped local content indicating a cache update time for when the local content cache is updated; and

a temporal filter, coupled to the control device, for filtering the temporal stamped local content with the temporal component to generate time of interest relevant information for the client output means.

12. The navigation system of claim 11 wherein the temporal filter is included in the client.

13. The navigation system of claim 11 wherein the temporal filter is for sorting the time of interest relevant information received from the server.

14. The navigation system of claim 11 wherein the temporal filter comprises a temporal input means to a receiver a user controlled temporal entry.

15. The navigation system of claim 11 wherein the client further comprises a GPS function means to detect and monitor a position of the client.

16. The navigation system of claim 11 wherein the client further comprises an input means for receiving an information request entry.

17. The navigation system of claim 11 wherein the client output means comprises a client display.

18. The navigation system of claim 11 wherein the client output means comprises an audio output means.

19. The navigation system of claim 11 wherein the client output means further comprises a user interface controller coupled to a client display.

20. The navigation system of claim 11 wherein the client output means further comprises a user interface controller coupled to control an audio-visual means.
