Abstract

A system for providing position-related information to a mobile user includes a central site server and mobile unit that has circuitry for allowing a user selection and for receiving position signals that may emanate from, for example, GPS satellites. The mobile unit further includes circuitry for establishing a wireless bidirectional communications link with the central site server via a terrestrial network such as a cellular telephone network, and sending position information and selection signals to the central site server. The central site server includes circuitry for receiving the present position information and selection signals selected by the user. Responsive thereto, the central site server retrieves corresponding response information, which is sent to the mobile unit via the bidirectional communications link. In one embodiment, communications between the mobile unit and the central site server are encrypted.

Claims

1. A system for providing information to a mobile user, the system comprising:

a mobile communication device including an input device configured to receive from an operator a selection signal indicative of at least one topic of interest;

a wireless communication network; and

at least one server configured to retrieve information corresponding to the present position of the mobile communication device and to at least one user selected topic of interest, the at least one server configured to send said retrieved information to the mobile communication device at least in part over said wireless communication network,

wherein the least one server is further configured to determine a dynamically adjustable refresh interval specifying how frequently the mobile communication device is to collect position signals from external sources and to send the dynamically adjustable refresh interval to the mobile communication device.

2. The system of claim 1, wherein said input device of the mobile communication device comprises a keypad and the selection signal corresponds to an alphanumeric entry on said keypad.

3. The system of claim 1, wherein said input device of the mobile communication device comprises a microphone and the selection signal comprises a voice signal received by said microphone.

4. The system of claim 1, wherein said mobile communication device comprises an analog wireless phone.

5. The system of claim 1, wherein said mobile communication device comprises a digital wireless phone.

6. The system of claim 1, wherein said mobile communication device comprises a laptop computer.

7. The system of claim 1, wherein said mobile communication device further comprises a receiver configured to receive position signals from a satellite positioning system.

8. The mobile communication device of claim 7, wherein the receiver comprises a global positioning system (GPS) receiver.

9. The system of claim 1, wherein the information provided to the mobile user includes audio content.

10. The system of claim 1, wherein the information provided to the mobile user includes video content.

11. The system of claim 1, wherein the information provided to the mobile user includes text content.

12. The system of claim 1, wherein the information provided to the mobile user includes image content.

13. An apparatus for supplying information to a mobile communication device over a communication network, comprising:

an interface configured for receiving information indicative of a present position of the mobile communication device and for receiving at least one user-selected topic of interest;

means for retrieving information corresponding to the present position of a mobile communication device and corresponding to at least one user-selected topic of interest;

means for determining a dynamically adjustable refresh interval specifying how frequently the mobile communication device is to collect position signals from external sources; and

means for sending the retrieved position-related information to the mobile communication device and for sending the dynamically adjustable refresh interval to the mobile communication device.

14. The apparatus of claim 13, wherein the position-related information includes audio content.

15. The apparatus of claim 13, wherein the position-related information includes video content.

16. The apparatus of claim 13, wherein the position-related information includes text content.

17. The apparatus of claim 13, wherein the position-related information includes image content.

18. A method for providing information from a server, said method comprising:

receiving at said server at least one user selected topic of interest;

receiving at said server the position of a mobile communication device;

providing from said server to said mobile communication device information corresponding to said position and to the at least one user selected topic of interest;

determining a dynamically adjustable refresh interval specifying how frequently the mobile communication device is to collect position signals from external sources; and

sending the dynamically adjustable refresh interval to the mobile communication device.

19. The method of claim 18, wherein said mobile communication device includes a satellite positioning system receiver.

20. The method of claim 19, comprising:

receiving positioning signals with said satellite positioning system receiver of the mobile communication device; and

deriving the position of the mobile communication device at least in part from said received positioning signals.

21. A method for providing position-related information from a mobile communication device to a server, the method comprising:

receiving at the mobile communication device position signals from external sources;

receiving at the mobile communication device a dynamically adjustable refresh interval from the server to specify how frequently the mobile communication device is to collect position signals from the external sources; and

updating position-related information at the mobile station responsive to the received position signals in accordance with the dynamically adjustable refresh interval.

22. The method of claim 21, further comprising sending a refresh interval request from the mobile station to the server.

23. The method of claim 21, further comprising providing the updated position-related information from the mobile communication device to the server.

24. The method of claim 23, wherein the updated position-related information is provided by the mobile communication device to the server periodically in accordance with the dynamically adjustable refresh interval.

25. The method of claim 23, wherein the updated position-related information is provided by the mobile communication device to the server upon request from the server.

26. The method of claim 21, wherein the position signals include global positioning system (GPS) signals.

32. The method of claim 21, further comprising disabling, between position refreshes specified by the dynamically adjustable refresh interval, GPS receiver hardware used to collect the position signals.

33. The method of claim 32, further comprising automatically re-enabling, at each position refresh specified by the dynamically adjustable refresh interval, the GPS receiver hardware used to collect the position signals.

27. A method for receiving position-related information by a server from a mobile communication device, the method comprising:

determining at the server a dynamically adjustable refresh interval to specify how frequently the mobile communication device is to collect position signals from external sources;

sending the dynamically adjustable refresh interval to the mobile communication device; and

receiving updated position-related information at the server based on position signals collected by the mobile communication device in accordance with the dynamically adjustable refresh interval.

28. The method of claim 27, further comprising receiving a refresh interval request from the mobile station.

29. The method of claim 27, further comprising requesting updated position-related information from the mobile communication device.

30. The method of claim 27, wherein the updated position-related information is received by the server from the mobile communication device periodically in accordance with the dynamically adjustable refresh interval.

31. The method of claim 27, wherein the position signals include global positioning system (GPS) signals.
