Abstract

In one embodiment, a mobile client system may determine its location. The mobile client system may store the location in a location history in a memory of the mobile client system, where the location history comprises one or more geographic locations and one or more time stamps corresponding to each of the geographic locations. The mobile client system may detect its current status based at least in part on whether the mobile client system is stationary. The mobile client system may send the location history to a location server of an online social network based at least in part on the current status of the mobile client system and a power requirement for sending the location history to the location server.

Claims

1. A method comprising, by a mobile-client system:

determining a location of the mobile-client system;

storing the location in a location history in a memory of the mobile-client system, wherein the location history comprises;

one or more geographic locations; and

one or more time stamps corresponding to each of the geographic locations;

detecting a current status of the mobile-client system based at least in part on whether the mobile-client system is stationary; and

sending the location history to a location server of an online social network based at least in part on the current status of the mobile-client system and a power requirement for sending the location history to the location server.

2. The method of claim 1, wherein determining the location of the mobile-client system comprises accessing one or more of a global position system (GPS) signal, a Wi-Fi signal, or a cellular radio signal.

3. The method of claim 1, wherein the location history at the location server further comprises check-in activities of a user of the online social network associated with the mobile-client system.

4. The method of claim 1, wherein the location history at the location server further comprises locations tagged by a user of the online social network associated with the mobile-client system.

5. The method of claim 1, wherein the mobile-client system updates the location history at a predetermined time interval.

6. The method of claim 5, wherein the predetermined time interval is specified by a server of the online social network.

7. The method of claim 5, wherein the predetermined time interval is specified by the mobile-client system.

8. The method of claim 5, wherein the location history is sent to the online social network at a predetermined time interval.

9. The method of claim 8, wherein the predetermined time interval is specified by a server of the online social network.

10. The method of claim 8, wherein the predetermined time interval is specified by the mobile-client system.

11. The method of claim 8, wherein the predetermined time interval is based at least in part on an operating system of the mobile-client system.

12. The method of claim 1, wherein the location server may request the location history from the mobile-client system in response to a request by a user of the online social network for the location of a user associated with the mobile-client system.

13. The method of claim 1, wherein the current status of the mobile-client system is determined by an accelerometer of a gyroscope of the mobile-client system.

14. The method of claim 1, wherein the mobile-client system is stationary if the mobile-client system determines it is moving at a walking speed.

15. The method of claim 1, wherein the mobile-client system sends the location history to the location server in response to determining that the mobile-client system is no longer stationary.

16. The method of claim 1, wherein the mobile-client system sends the location history to the location server through an existing connection between the mobile-client system and the location server.

17. The method of claim 1, wherein the mobile-client system establishes a new connection to the location server to send the location history to the location server.

18. The method of claim 1, wherein if the mobile-client system is determined to not be stationary, then reducing a sampling duration for determining the location of the mobile-client system.

19. One or more computer-readable non-transitory storage media embodying software that is operable when executed to:

determine a location of the mobile-client system;

store the location in a location history in a memory of the mobile-client system, wherein the location history comprises;

one or more geographic locations; and

one or more time stamps corresponding to each of the geographic locations;

detect a current status of the mobile-client system based at least in part on whether the mobile-client system is stationary; and

send the location history to the location server of an online social network based at least in part on the current status of the mobile-client system and the power required for sending the location history to the location server.

20. A system comprising:

one or more processors; and

a memory coupled to the processors comprising instructions executable by the processors, the processors operable when executing the instructions to;

determine a location of the mobile-client system;

store the location in a location history in a memory of the mobile-client system, wherein the location history comprises;

one or more geographic locations; and

one or more time stamps corresponding to each of the geographic locations;

detect a current status of the mobile-client system based at least in part on whether the mobile-client system is stationary; and

send the location history to the location server of an online social network based at least in part on the current status of the mobile-client system and the power required for sending the location history to the location server.
