Abstract

Systems and methods that utilize femtocell access points (FAP) to perform radio frequency (RF) network sweeps are provided. In one embodiment, a method includes: predicting an availability of an access point (AP) to perform an RF network sweep; and determining that the access point is available to perform the RF network sweep based, at least, on a prediction that a mobile device on a white list for the access point is not likely to access the access point during a time interval associated with performing the RF network sweep. In another embodiment, a method includes: comparing a network quality characteristic for a wireless channel associated with a FAP with a network quality characteristic for a wired network communicatively coupled to the FAP. The network quality characteristics can be the same. The method can then include employing the comparison to determine to which network an impairment is attributable.

First claim

What is claimed is:

1. A method, comprising:
determining, by a device comprising a processor, a probability relating to whether a mobile device is likely to access an access point device during a time interval associated with performing a radio frequency network sweep, wherein the determining the probability comprises:
determining a pattern of movement of the mobile device based on estimating a time of arrival of the mobile device at a location of a geographical region, and wherein the estimating is based on duration information representing a duration of a communication session associated with the mobile device; and

transmitting, by the device, information to a controller of the access point device based on the probability.

2. The method of claim 1 , wherein the estimating is further based on an estimated speed of travel of the mobile device.

3. The method of claim 1 , further comprising determining, by the device, that the access point device is not available to perform the radio frequency network sweep in response to determining that the mobile device is likely to access the access point device during the time interval associated with performing the radio frequency network sweep.

4. The method of claim 1 , wherein the information authorizes the controller to transmit a command to the access point device to perform the radio frequency network sweep.

5. The method of claim 1 , wherein the access point device is a femtocell access point device.

6. The method of claim 1 , wherein the location of the geographical region is a first location, and wherein the determining the probability further comprises:
determining a second location of the mobile device, and
determining whether the second location of the mobile device is within a defined geographic proximity to the access point device.

7. The method of claim 1 , wherein the determining the probability further comprises:
determining a time of day for the access point device to perform the radio frequency network sweep.

8. The method of claim 7 , wherein the determining the probability further comprises:
determining whether data representing a history of usage of the access point device by the mobile device indicates that the mobile device will be present in an area covered by the access point device and access the access point device during a selected time of day.

9. The method of claim 1 , wherein the determining the probability further comprises:
identifying a public cell site device associated with the access point device; and
determining whether the mobile device is currently accessing the public cell site device associated with the access point device.

10. The method of claim 1 , wherein the determining the probability further comprises:
determining that the mobile device is unable to be located.

11. The method of claim 1 , wherein the determining the pattern of movement further comprises:
determining a likelihood that the mobile device will arrive within the geographical region during an active communication session in progress with the mobile device.

12. A system, comprising:
a processor; and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
determining a probability relating to whether a mobile device will access an access point device during a time interval associated with performing a radio frequency network sweep, wherein the determining the probability comprises:
determining a pattern of movement of the mobile device based on estimating a time of arrival of the mobile device at a location of a geographical region, and wherein the estimating is based on duration information representing a duration of a communication associated with the mobile device, and
transmitting information to a controller of the access point device based on the probability.

13. The system of claim 12 , wherein the operations further comprise determining that the access point device is not available to perform the radio frequency network sweep in response to alternatively determining that the mobile device is likely to access the access point device during the time interval associated with performing the radio frequency network sweep.

14. The system of claim 12 , wherein the information authorizes the controller to transmit a command to the access point device to perform the radio frequency network sweep.

15. The system of claim 12 , wherein the access point device is a femtocell access point device.

16. The system of claim 12 , wherein the location of the geographical region is a first location, and wherein the determining the probability further comprises:
determining a second location of the mobile device, and
determining whether the second location of the mobile device is within a defined geographic proximity to the access point device.

17. A non-transitory machine-readable storage medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:
determining a probability associated with whether a mobile device is likely to access an access point device during a time interval associated with performing a radio frequency network sweep, wherein the determining the probability comprises:
determining a pattern of movement of movement of the mobile device based on estimating a time of arrival of the mobile device at a location of a geographical region, and wherein the estimating is based on duration information representing a duration of a communication session associated with the mobile device, and
transmitting, by the device, information to a controller of the access point device based on the probability.

18. The non-transitory machine-readable storage medium of claim 17 , wherein the determining the probability further comprises:
determining whether data representing a history of usage of the access point device by the mobile device indicates that the mobile device is likely to be present in an area covered by the access point device and access the access point device during a selected time of day.

19. The non-transitory machine-readable storage medium of claim 17 , wherein the determining the probability further comprises:
identifying a public cell site device associated with the access point device, and
determining whether the mobile device is currently accessing the public cell site device associated with the access point device.

20. The non-transitory machine-readable storage medium of claim 17 , wherein the determining the probability further comprises:
determining that the mobile device is unable to be located.
