Abstract

The invention relates to a method and an apparatus for updating application information of an application in a portable communication device. The updating involves determining the current location and the connectivity to a communication network, adaptively creating a visitation history based on the current position and previously visited locations of the portable communication device, and also on the connectivity to a communication network of the current and previously visited locations. Then the next visitation location is predicted based on the visitation history, and if the next location is determined to not have any connectivity, up-to-date application information is downloaded from a server for updating the application information in the portable communication device.

Claims

1. A method for updating application information of an application in a portable communication device comprising:

determining the current location of said portable communication device;

determining the connectivity of said portable communication device to a communication network for said current location;

adaptively creating a visitation history based on said current location, said connectivity, and on previously visited locations of said portable communication device and the connectivity of said previously visited locations;

predicting a next location of said portable communication device based on said current location and said visitation history;

determining, based on said visitation history, if said next location provides connectivity to a communication network;

if said next location is determined to provide no connectivity to said communication network, then initiating downloading of information from a server on said communication network; and

updating said application information in said portable communication device with said downloaded information.

2. The method according to claim 1, further comprises:

determining if said application has been executed in said portable communication device at said current location.

3. The method according to claim 2, wherein the step of adaptively creating said visitation history further is based on if said application has been executed in said portable communication device at said current location or at said previously visited locations.

4. The method according to claim 3, further comprises:

determining if said application have been executed at said next location determined to have no connectivity to a communication network; and

if said application has been used at said next location determined to have no connectivity to a communication network, then

updating said application information in said portable communication device with said downloaded information.

5. The method according to claim 1, wherein said updating of said application information comprises:

comparing said application information with said downloaded information; and

replacing said application information with said downloaded information if said application information is older than said downloaded information.

6. The method according to claim 1, wherein the step of determining the current location is performed by Enhanced Observed Time Difference of a network cell or by determining the position of said portable communication device using a global positioning system, or both.

7. The method according to claim 1, wherein said application is an altimeter application.

8. The method according to claim 1, wherein said application information is air pressure at sea level data.

9. The method according to claim 1, wherein said server on said communication network is a weather service server on the Internet.

10. An apparatus for updating application information of an application in a portable communication device comprising:

a first determining unit configured to determine the current location of said portable communication device;

a second determining unit configured to determine the connectivity of said portable communication device to a communication network for said current location;

a compiler configured to adaptively create a visitation history based on said current location, said connectivity, and on previously visited locations of said portable communication device and the connectivity of said previously visited locations;

a prediction unit configured to predict a next location of said portable communication device based on said current location and said visitation history;

a third determining unit configured to determine, based on said visitation history, if said next location provides connectivity to a communication network;

a decision unit configured to initiate downloading, in a downloading unit configured to download information from a server on said communication network, if said next location is determined to provide no connectivity to said communication network; and

an updating unit adapted to update said application information in said portable communication device with said downloaded information.

11. The apparatus according to claim 10, further comprises:

a fourth determining unit configured to determine if said application has been executed in said portable communication device at said current location.

12. The apparatus according to claim 11, wherein the compiler is further configured to base the creation of said visitation history on if said application has been executed in said portable communication device at said current location or at said previously visited locations.

13. The apparatus according to claim 12, further comprises:

a fifth determining unit configured to determine if said application have been executed at said next location determined to have no connectivity to a communication network; and

wherein the

a decision unit is further configured to download information from said server on said communication network, if said next location is determined to provide no connectivity to said communication network and if said application is determined to have been used at said next location determined to have no connectivity to a communication network;

then

wherein said updating unit is configured to update said application information in said portable communication device with said downloaded information.

14. The apparatus according to claim 10, wherein said updating unit further comprises:

a comparing unit configured to compare said application information with said downloaded information; and

a replacing unit configured to replace said application information with said downloaded information if said application information is older than said downloaded information.

15. The apparatus according to claim 10, wherein the determining of the current location in the first determining unit is performed by Enhanced Observed Time Difference of a network cell or by determining the position of said portable communication device using a global positioning system, or both.
