Abstract

Provided herein are system, methods and computer readable storage media in facilitating the determination of a location of at least one mobile device. In providing such functionality, the system may be configured to, for example, receive contextual data corresponding to a contextual state of a mobile device, determine the location of a mobile device, and transmit the location of the mobile device to at least one other mobile device.

Claims

1. A method for tracking a location of at least one mobile device, the method comprising:

receiving mobile device contextual data;

determining a velocity and acceleration of the mobile device;

predicting a future location of the mobile device;

determining a new location of the mobile device; and

transmitting data corresponding to the new location of the mobile device.

2. The method of claim 1, wherein the new location of the mobile device is based at least in part on the predicted future location of the mobile device.

3. The method of claim 1, wherein predicting a future location of the mobile device further comprises predicting the future location based at least on one Kalman filter and Markov chain.

4. The method of claim 1, wherein determining a new location of the mobile device further comprises:

determining the predicted future location of the mobile device has not met an accuracy threshold;

receiving data corresponding to a location of at least one device in communication with the mobile device; and

determining a location of the mobile device based at least upon the data corresponding to the location of the at least one device in communication with the mobile device.

5. The method of claim 1, wherein determining a new location of the mobile device further comprises:

determining the predicted future location of the mobile device has not met an accuracy threshold;

transmitting a signal to the mobile device corresponding to a request for the new location of the mobile device; and

receiving data corresponding to a current location of the mobile device.

6. The method of claim 1, wherein receiving mobile device contextual data further comprises at least one of:

receiving mobile device audio data;

receiving mobile device video data;

receiving mobile device velocity data; and

receiving mobile device acceleration data.

7. The method of claim 1 further comprising receiving a signal from a first mobile device corresponding to a location request of at least one other mobile device.

8. The method of claim 6 further comprising:

receiving a plurality of signals from a plurality of mobile devices, each of the signals corresponding to a location request of at least one other mobile device; and

determining whether any duplication exists between any of the location requests for any of the at least one other mobile device.

9. The method of claim 1, wherein the mobile device is configured to maintain an open socket connection with a mobile device locating system with a VoIP protocol.

10. The method of claim 9, wherein the mobile device is configured to remain in a low powered state while maintaining the open socket connection.

11. A computer program product comprising:

at least one computer readable non-transitory memory medium having program code instructions stored thereon, the program code instructions which when executed by an apparatus cause the apparatus at least to;

receive mobile device contextual data;

determine a velocity and acceleration of the mobile device;

predict a future location of the mobile device;

determine a new location of the mobile device; and

transmit data corresponding to the new location of the mobile device.

12. The computer program product according to claim 11, wherein the new location of the mobile device is based at least in part on the predicted future location of the mobile device.

13. The computer program product according to claim 11, wherein the wherein the program code instructions are further configured to, when executed by the apparatus, cause the apparatus at least to:

predict a future location of the mobile device based at least on one Kalman filter and Markov chain.

14. The computer program product according to claim 11, wherein the program code instructions are further configured to, when executed by the apparatus, cause the apparatus at least to:

determine the predicted future location of the mobile device has not met an accuracy threshold;

receive data corresponding to a location of at least one device in communication with the mobile device; and

determine a location of the mobile device based at least upon the data corresponding to the location of the at least one device in communication with the mobile device.

15. The computer program product according to claim 11, wherein the program code instructions are further configured to, when executed by the apparatus, cause the apparatus at least to:

determine the predicted future location of the mobile device has not met an accuracy threshold;

transmit a signal to the mobile device corresponding to a request for the new location of the mobile device; and

receive data corresponding to a current location of the mobile device.

16. The computer program product according to claim 11, wherein the program code instructions are further configured to, when executed by the apparatus, cause the apparatus at least to:

receive mobile device audio data;

receive mobile device video data;

receive mobile device velocity data; and

receive mobile device acceleration data.

17. The computer program product according to claim 11, wherein the program code instructions are further configured to, when executed by the apparatus, cause the apparatus at least to receive a signal from a first mobile device corresponding to a location request of at least one other mobile device.

18. The computer program product according to claim 17, wherein the program code instructions are further configured to, when executed by the apparatus, cause the apparatus at least to:

receive a plurality of signals from a plurality of mobile devices, each of the signals corresponding to a location request of at least one other mobile device; and

determine whether any duplication exists between any of the location requests for any of the at least one other mobile device.

19. The computer program product according to claim 11, wherein the program code instructions are further configured to, when executed by the apparatus, cause the apparatus at least to maintain an open socket connection with a mobile device locating system with a VoIP protocol.

20. The computer program product according to claim 19, wherein the program code instructions are further configured to, when executed by the apparatus, cause the apparatus at least to maintain an open socket connection in a low powered state while maintaining the open socket connection.

21. An apparatus comprising:

at least one processor; and

at least one memory, the memory including computer program instructions which when executed, in conjunction with the at least one processor, are configured to cause the apparatus to;

receive mobile device contextual data;

determine a velocity and acceleration of the mobile device;
