Abstract

A mobile computing device comprising a transceiver circuit configured to communicate with a wireless network. The mobile computing device includes a memory configured to store a wireless network coverage data and a geographic data; a location determination circuit configured to provide a location data for the mobile computing device; and a processing circuit configured to determine that the mobile computing device is in a transition zone and to download via the transceiver circuit additional geographic data based on the determination.

Claims

1. A mobile computing device, comprising:

a transceiver circuit configured to communicate with a wireless network;

a memory configured to store a wireless network coverage data and a geographic data;

a location determination circuit configured to provide a location data for the mobile computing device; and

a processing circuit configured to determine that the mobile computing device is in a transition zone and to download via the transceiver circuit additional geographic data based on the determination.

2. The mobile computing device of claim 1, wherein the processing circuit is configured to determine the transition zone based on the wireless network coverage data and the location data.

3. The mobile computing device of claim 1, wherein the processing circuit is configured to determine that a destination location is in a no service area;

and

wherein the processing circuit downloads via the transceiver circuit a first map data associated with a route to the destination location and a second map data associated with the no service zone from a remote source.

4. The mobile computing device of claim 1, wherein the additional geographic data comprises at least one point of interest information.

5. The mobile computing device of claim 1, wherein the geographic data comprises at least one street data for a geographic area and the street data is configured to include at least one lower level of street data for the geographic area.

6. The mobile computing device of claim 1, wherein the location determination circuit is configured to provide the location data based on a position data received from the wireless network.

7. The mobile computing device of claim 1, wherein the processing circuit is configured to determine the mobile computing device is in the transition zone based on a course prediction which is configured to be based on at least one past location data.

8. A mobile computing device, comprising:

a transceiver circuit configured to communicate with a wireless network;

a memory configured to store a wireless network coverage data and a geographic data;

a location determination circuit configured to provide a location data for the mobile computing device; and

a processing circuit configured to determine that the mobile computing device is proximate to a wireless network coverage area boundary line and to download via the transceiver circuit additional geographic data based on the determination.

9. The mobile computing device of claim 8, wherein the processing circuit is configured to determine that the mobile computing device is proximate to the wireless network coverage area boundary line based on the wireless network coverage data and the location data.

10. The mobile computing device of claim 8, wherein the processing circuit is configured to determine that the mobile computing device is in proximate to the wireless network coverage area boundary line based on a wireless network signal strength.

11. The mobile computing device of claim 8, wherein the processing circuit is configured to determine that a destination location is in a no service area;

and

wherein the processing circuit downloads via the transceiver circuit a first map data associated with a route to the destination location and a second map data associated with the no service zone from a remote source.

12. The mobile computing device of claim 8, wherein the additional geographic data comprises at least one point of interest information.

13. The mobile computing device of claim 8, wherein the location determination circuit is configured to provide the location data based on a local global positioning system receiver.

14. The mobile computing device of claim 8, wherein the transceiver is configured to communicate with a cellular wireless network.

15. The mobile computing device of claim 8, wherein the additional geographic data is determined via a logic circuit.

16. A method for navigation, comprising:

determining a mobile computing device location;

determining a transition zone;

determining that the mobile computing device location is within the transition zone; and

downloading at least one map outside of a wireless network coverage area to the mobile computing device from a remote source.

17. The method for navigation of claim 16, wherein the downloading of the at least one map and the at least one navigation command is based on a logic circuit.

18. The method of navigation of claim 16, wherein the mobile computing device downloads at least one point of interest from a remote source.

19. The method for navigation, comprising:

entering a destination location on a mobile computing device;

determining that the destination location is within a no service zone; and

downloading a first map data associated with a route to the destination location and a second map data associated with the no service zone from a remote source.

20. The method of navigation of claim 19, wherein the mobile computing device downloads at least one point of interest from a remote source.
