Abstract

Determining levels of geographic redundancy among radios of a wireless radio network is disclosed. The level of geographic redundancy for a radio can affect the determination of location information for a user equipment (UE) on the wireless radio network. The disclosed subject matter can be employed in conjunction with timed fingerprint location (TFL) technologies to facilitate selection of radios employed in determining time values for TFL location determination. Levels of geographic redundancy can be employed to rank or order radios of a wireless radio network so as to reduce the likelihood of using geographically redundant radios in location determination. Further, rules can be selected to adjust threshold values and equations employed in determining the levels of geographic redundancy. Moreover, rules can be selected to apply boundary conditions to reduce the number of determinations formed for a set of radios of the wireless radio network.

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;

in response to receiving an indication of a change in geographic information relating to a first radio of a wireless network, updating a level of geographic redundancy associated with the first radio and a second radio of the wireless network;

determining a rank value of the first radio based on the level of geographic redundancy; and

in response to the rank value being determined to have satisfied a selection rule, updating first timed fingerprint location information corresponding to the first radio.

2. The system of claim 1, wherein the updating the level of geographic redundancy comprises determining an error in location accuracy associated with a location change for the first radio corresponding to the change in the geographic information relating to the first radio.

3. The system of claim 2, wherein the location change results from the first radio having been physically moved from a first location to a second location different from the first location.

4. The system of claim 2, wherein the location change results from the first radio having been newly added to the wireless network at a first location.

5. The system of claim 1, wherein the determining the rank value comprises updating a previous rank value of the first radio.

6. The system of claim 5, wherein the updating the previous rank value of the first radio results in increasing the rank value over the previous rank value.

7. The system of claim 5, wherein the updating the previous rank value of the first radio results in decreasing the rank value from the previous rank value.

8. The system of claim 5, wherein the updating the previous rank value of the first radio results in the rank value remaining unchanged from the previous rank value.

9. A method, comprising:

determining, by a system comprising a processor, a change in geographic information for a first radio corresponding to a change in a location of the first radio;

updating, by the system, a level of geographic redundancy for the first radio, in relation to a second radio, based on first geographic information of the first radio and second geographic information of the second radio, wherein the first geographic information corresponds to the change in the geographic information for the first radio;

updating, by the system, a rank of the first radio in response to the updating the level of geographic redundancy; and

updating, by the system, first timed fingerprint location information corresponding to the first radio in response to the rank having been determined to satisfy a selection rule.

10. The method of claim 9, wherein the change in the location of the first radio results from the first radio being physically relocated from a first location to a second location.

11. The method of claim 9, wherein the change in the location of the first radio results from a first physical location of the first radio determined via a first location technology being different from a second physical location of the first radio determined via a second location technology.

12. The method of claim 9, wherein the change in the location of the first radio results from the first radio being newly added at a first location.

13. The method of claim 9, wherein the updating the rank of the first radio results in the rank of the first radio being increased relative to a previous rank of the first radio.

14. The method of claim 9, wherein the updating the rank of the first radio results in the rank of the first radio being decreased relative to a previous rank of the first radio.

15. The method of claim 9, wherein the updating the rank of the first radio results in the rank of the first radio remaining unchanged relative to a previous rank of the first radio.

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

in response to detecting a change in a location of a first radio from a first location to a second location, updating a level of geographic redundancy for the first radio in relation to a second radio based on first geographic information of the first radio and second geographic information of the second radio, wherein the first geographic information corresponded to the second location of the first radio;

in response to updating the level of geographic redundancy, determining a rank value of the first radio based on the level of geographic redundancy; and

enabling access to first timed fingerprint location information corresponding to the first radio, wherein the first timed fingerprint location information is updated in response to the rank value being determined to have satisfied a selection rule.

17. The non-transitory machine-readable storage medium of claim 16, wherein the first radio is physically relocated from the first location to the second location.

18. The non-transitory machine-readable storage medium of claim 16, wherein the first location is different from the second location as a result of employing a first location technology to determine the first location, and a second location technology to determine the second location, and wherein the first location technology and the second location technology are different location technologies.

19. The non-transitory machine-readable storage medium of claim 16, wherein the rank value is different from a previous rank value of the first radio.

20. The non-transitory machine-readable storage medium of claim 16, wherein the rank value is a same rank as a previous rank value of the first radio.
