Abstract

Site location determination using crowd sourced propagation delay and location data is provided. A propagation delay component receives a set of propagation delay measurements for communications between a mobile device and an access point. A user equipment location component receives a location of the mobile device, and a combination component combines the set of propagation delay measurements and the location into a set of location data. An access point location component determines a set of intersecting locations between the set of location data and additional sets of location data, and determines a location of the access point based on the set of intersecting locations.

Claims

1. A system, comprising:

a processor; and

a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising;

generating first flag data associated with a first flagging of an estimated location of an access point device as not corresponding to an actual location of the access point device;

comparing the estimated location of the access point device to geographical data related to a topology of the estimated location of the access point device;

based on the comparing, determining that the estimated location is an improbable location of the access point device; and

generating second flag data associated with a second flagging of the estimated location as a location satisfying a defined criterion.

2. The system of claim 1, wherein the operations further comprise:

determining the estimated location of the access point device is the improbable location according to an improbability criterion.

3. The system of claim 2, wherein the determining the estimated location of the access point device is the improbable location according to the improbability criterion is based on a result of a first location data of the mobile device of mobile devices.

4. The system of claim 3, wherein the determining the estimated location of the access point device is the improbable location according to the improbability criterion comprises determining intersecting locations related to the mobile devices.

5. The system of claim 3, wherein the determining the estimated location of the access point device is the improbable location according to the improbability criterion comprises determining that the estimated location satisfies an error threshold.

6. The system of claim 5, wherein the error threshold is a difference between a first propagation delay and a second propagation delay associated with signals between the mobile device and the access point device, and wherein the first propagation delay is less than the second propagation delay.

7. The system of claim 3, wherein the determining the estimated location of the access point device is the improbable location according to the improbability criterion comprises determining that the estimated location does not satisfy an error threshold.

8. The system of claim 1, wherein the operations further comprise:

in response to the first flag data and the second flag data being generated, instructing a cell site device to increase a sample size associated with the estimated location.

9. The system of claim 1, wherein the operations further comprise:

sending, to a network device of a wireless network, improbable location data, representative of the improbable location, to facilitate modeling of network devices of the wireless network comprising the access point device.

10. The system of claim 1, wherein the operations further comprise:

determining that a propagation delay measurement does not comprise a compensation factor for a length of a connection between an antenna of the access point device and base station equipment for the access point device.

11. A method, comprising:

generating, by a device comprising a processor, first flag data associated with a first flagging of an estimated location of an access point device as not corresponding to an actual location of the access point device;

comparing, by the device, the estimated location of the access point device to geographical data related to a topology of the estimated location of the access point device;

based on the comparing, determining, by the device, that the estimated location is an improbable location of the access point device; and

generating, by the device, second flag data associated with a second flagging of the estimated location as a location satisfying a defined criterion.

12. The method of claim 11, further comprising:

determining, by the device, the estimated location of the access point device is the improbable location according to an improbability criterion.

13. The method of claim 12, wherein the determining the estimated location of the access point device is the improbable location according to the improbability criterion is based on a result of a first location data of the mobile device of mobile devices.

14. The method of claim 13, wherein the determining the estimated location of the access point device is the improbable location according to the improbability criterion comprises determining intersecting locations related to the mobile devices.

15. The method of claim 13, wherein the determining the estimated location of the access point device is the improbable location according to the improbability criterion comprises determining that the estimated location satisfies an error threshold.

16. The method of claim 15, wherein the error threshold is a difference between a minimum propagation delay and a maximum propagation delay of signals between the mobile device and the access point device.

17. The method of claim 13, wherein the determining the estimated location of the access point device is the improbable location according to the improbability criterion comprises determining that the estimated location does not satisfy an error threshold.

18. The method of claim 11, further comprising:

in response to the first flag data and the second flag data being generated, instructing, by the device, a cell site device to increase a sample size associated with the estimated location.

19. A machine-readable storage medium comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:

generating first flag data associated with a first flagging of an estimated location of an access point device as not corresponding to an actual location of the access point device;

comparing the estimated location of the access point device to geographical data related to a topology of the estimated location of the access point device;

based on a result of the comparing, determining that the estimated location is an improbable location of the access point device; and

generating second flag data associated with a second flagging of the estimated location as a location satisfying a defined criterion.
