Method for estimating location, and electronic device and server thereof

1. A method for estimating a location of an external electronic device in communication with an electronic device, the method comprising:

receiving, from a server, a policy for collecting external electronic device information, wherein the policy includes a predetermined time interval at which the electronic device reports the external electronic device information to the server;

collecting the external electronic device information from the external electronic device, wherein the external electronic device information includes time information that is proportional to a distance between the electronic device and the external electronic device communicating with the electronic device;

obtaining location information of the electronic device for each location where the external electronic device information is collected;

identifying the predetermined time interval included in the policy; and

transmitting the external electronic device information and the location information to the server to be used to estimate the location of the external electronic device at the predetermined time interval, based on the policy.

2. The method of claim 1 , wherein the time information includes timing advance and the external electronic device includes at least one of a base station or access point.

3. The method of claim 1 , wherein the policy further includes at least one criterion for reporting the external electronic device information to the server.

5. The method of claim 3 , wherein transmitting the external electronic device information and the location information comprises transmitting the external electronic device information and the location information of the electronic device at the predetermined time interval corresponding to the criterion for reporting, which is included in the policy.

6. The method of claim 3 , wherein collecting the external electronic device information comprises collecting the external electronic device information at a measurement interval included in the policy, if the external electronic device corresponds to target external electronic device information included in the policy.

7. The method of claim 3 , wherein the location information is location information having a higher accuracy than a threshold included in the policy.

8. The method of claim 1 , wherein the external electronic device information further includes at least one of an identifier (ID) of the external electronic device, a received signal strength indicator (RSSI) and a reference signal received power (RSRP).

9. The method of claim 1 , wherein the location information includes at least one of global positioning system (GPS) information and a GPS accuracy.

10. A method for estimating location of an external electronic device in a server, the method comprising:

transmitting a policy for collecting external electronic device information to an electronic device, wherein the policy includes a predetermined time interval at which the electronic device reports the external electronic device information to the server;

receiving, from the electronic device, the external electronic device information and location information of the electronic device at the predetermined time interval, the external electronic device information including time information that is proportional to a distance between the electronic device and the external electronic device communicating with the electronic device, wherein the location information is for each location where the external electronic device information is collected; and

estimating the location of the external electronic device based on the time information and the location information.

11. The method of claim 10 , wherein the time information includes timing advance and the external electronic device includes at least one of a base station or access point.

12. The method of claim 10 , wherein estimating the location of the external electronic device comprises:

calculating a distance between the location where the external electronic device information is collected, and each of a plurality of candidate locations of the external electronic device, based on the location information;

calculating a correlation between the calculated distance and the time information; and

determining one of the plurality of candidate locations as the location of the external electronic device based on the correlation.

13. The method of claim 10 , wherein the policy further includes a criterion for reporting the external electronic device information.

14. The method of claim 13 , wherein the policy includes at least one of target external electronic device information and an accuracy threshold of the location information.

15. The method of claim 14 , wherein the external electronic device information further includes at least one of an identifier (ID) of the external electronic device, a received signal strength indicator (RSSI) and a reference signal received power (RSRP), and wherein the external electronic device information is filtered by the policy.

16. The method of claim 10 , wherein the location information includes at least one of global positioning system (GPS) information and a GPS accuracy.

17. An electronic device comprising:

a communication unit;

a memory; and

a processor configured to:

control the communication unit to communicate with an external electronic device;

control the communication unit to receive a policy for collecting external electronic device information from a server, wherein the policy includes a predetermined time interval at which the electronic device reports the external electronic device information to the server;

control the communication unit to collect the external electronic device information from the external electronic device, wherein the external electronic device information includes time information that is proportional to a distance between the electronic device and the external electronic device;

obtaining location information of the electronic device for each location where the external electronic device information is collected;

identify the predetermined time interval included in the policy; and

transmit the external electronic device information and the location information to the server to be used to estimate the location of the external electronic device at the predetermined time interval, based on the policy,

wherein the memory is configured to store the policy.

18. The electronic device of claim 17 , further comprising a short-range communication module configured to transmit the external electronic device information and the location information to the server.

19. The electronic device of claim 17 , wherein the time information includes timing advance and the external electronic device includes at least one of a base station or access point.

20. The electronic device of claim 17 , wherein the processor is configured to transmit at least a part of the external electronic device information corresponding to the policy among the collected external electronic device information.

21. The electronic device of claim 17 , wherein the policy includes at least one of target external electronic device information and an accuracy threshold of the location information.

22. The electronic device of claim 21 , wherein the location information is location information having a higher accuracy than an accuracy threshold of the location information, which is included in the policy.

23. The electronic device of claim 21 , wherein the processor is configured to collect the external electronic device information at a measurement interval included in the policy, if the external electronic device corresponds to the target external electronic device information included in the policy.
