Abstract

Wireless coverage data are associated with a geographic database that contains data that represent a road network in a geographic region. The wireless coverage data indicate areas within the geographic region in which navigation-related services or data from a navigation services provider are available wirelessly, or conversely, areas within the geographic region in which navigation-related services or data from a navigation services provider are not available wirelessly. An end user obtains the wireless coverage data. The wireless coverage data are used to indicate to the end user areas in which navigation-related services or data from the navigation services provider are available wirelessly or areas in which navigation-related services or data from the navigation services provider are not available wirelessly. The wireless coverage data may also be used to warn the end user when he/she is leaving an area in which navigation-related services or data from the navigation services provider are available wirelessly. Data for uncovered areas can be downloaded to an end user'"'"'s computing platform while the end user is still within an area in which navigation-related data from the navigation services provider are available wirelessly.

Claims

1. A method of operation for an end user'"'"'s mobile computing device that provides navigation-related services to an end user, the method comprising:

from the end user'"'"'s mobile computing device, maintaining a wireless communications link with a remotely located navigation services provider while said end user'"'"'s device is located in an area in which wireless navigation services coverage is available; and

prior to said end user'"'"'s device leaving the area in which wireless navigation services coverage is available, obtaining from the remotely located navigation services provider navigation-related data at least for an area in which navigation services coverage is unavailable.

2. The method of claim 1 wherein the navigation-related data includes traffic-related data for the area in which navigation services coverage is unavailable.

3. The method of claim 1 wherein the navigation-related data includes updates for the area in which navigation services coverage is unavailable.

4. The method of claim 1 wherein the navigation-related services include weather data.

5. The method of claim 1 wherein the navigation services provider includes navigation applications.

6. The method of claim 1 wherein the end user'"'"'s mobile computing device is a phone.
