Abstract

In accordance with one embodiment of the present disclosure, a method for mobility profiling includes collecting a plurality of locations of a mobile electronic device, determining at least one trajectory for the mobile electronic device from the plurality of locations, and storing the at least one trajectory in computer readable media. Each of the plurality of locations have a spatial and temporal component. Using the at least one trajectory, estimating a future location of the mobile electronic device, and communicating data to the mobile electronic device corresponding to the estimated future location such that the content of the communicated data is based on the future location.

Claims

collecting a plurality of locations of a mobile electronic device, each of the plurality of locations having a spatial and temporal component;

determining at least one trajectory for the mobile electronic device from the plurality of locations;

storing the at least one trajectory in computer readable media;

estimating, based on the at least one trajectory, a future location of the mobile electronic device, the future location having a spatial and a temporal component; and

communicating data to the mobile electronic device corresponding to the estimated future location, the content of the communicated data based on the future location.

2. The method of claim 1, further comprising determining a path traversed by the mobile electronic device by matching the plurality of trajectories to one or more elements of a map.

3. The method of claim 1, wherein the communicated data comprises information selected from the group consisting of:

a traffic condition;

a roadwork alert;

a route advisory;

a weather condition;

directory assistance;

an advertisement; and

directions.

4. The method of claim 1, further comprising communicating the estimated future location of the mobile electronic device to a database.

5. The method of claim 1, wherein the mobile electronic device is a device selected from the group consisting of:

a mobile phone;

a pager;

a personal digital assistant;

a handheld computer; and

a Global Positioning System handheld.

6. The method of claim 1, further comprising collecting the plurality of locations of the mobile electronic device during each day of seven consecutive days.

7. The method of claim 1, further comprising:

receiving a request for directions; and

sending the directions based at least in part on the determined trajectory.

8. The method of claim 1, wherein estimating, based on the determined trajectory, the future location of the mobile electronic device further comprises deriving the velocity of the mobile electronic device.

9. Logic encoded in computer-readable medium and operable to:

collect a plurality of locations of a mobile electronic device, each of the plurality of locations having a spatial and temporal component;

determine at least one trajectory traversed by the mobile electronic device from the plurality of locations;

store the at least one trajectory in computer readable media; and

estimate, based on the determined at least one trajectory, a future location of the mobile electronic device, the future location having a spatial and a temporal component; and

communicate data to the mobile electronic device corresponding to the estimated future location, the content of the communicated data based on the future location.

10. The method of claim 9, further comprising determining a path traversed by the mobile electronic device by matching the plurality of trajectories to one or more elements of a map.

11. The logic of claim 9, wherein the communicated data comprises information selected from the group consisting of:

a traffic condition;

a roadwork alert;

a route advisory;

a weather condition;

directory assistance;

an advertisement; and

directions.

12. The logic of claim 9, wherein the logic is further operable to communicate the estimated location of the mobile electronic device to a database.

13. The logic of claim 9, wherein the mobile electronic device is a device selected from the group consisting of:

a Global Positioning System handheld.

14. The logic of claim 9, wherein the logic is further operable to collect the plurality of locations of the mobile electronic device during each day of seven consecutive days.

15. The logic of claim 9, wherein the logic is further operable to:

receive a request for directions; and

send the directions based at least in part on the determined at least one trajectory.

16. The logic of claim 9, wherein:

the logic is further operable to derive the velocity of the mobile electronic device; and

the estimation is based on the determined at least one trajectory and the derived velocity.

17. A method comprising:
