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 geographic information relating to a first radio and a second radio of a wireless network, determining a level of geographic redundancy associated with the first radio and second radio;

selecting the first radio based on the level of geographic redundancy being determined to have satisfied a first rule related to a threshold redundancy level; and

enabling, for a device associated with a request for time fingerprint location information, access to first timed fingerprint location information corresponding to the first radio.

2. The system of claim 1, wherein the determining the level of geographic redundancy comprises determining an error in location accuracy associated with determining a location based on the first timed fingerprint location information corresponding to the first radio and second timed fingerprint location information corresponding to the second radio.

3. The system of claim 1, wherein access to second timed fingerprint location information corresponding to the second radio is deprioritized relative to the first timed fingerprint location information.

4. The system of claim 1, wherein access to first timed fingerprint location information corresponding to the first radio is prioritized relative to the second timed fingerprint location information.

5. The system of claim 1, wherein the level of geographic redundancy is a first level of geographic redundancy, and wherein the selecting the first radio is based on the first level of geographic redundancy being determined to have satisfied the first rule related to the threshold redundancy level and a second level of geographic redundancy associated with the first radio and a third radio being determined to have satisfied the first rule related to the threshold redundancy level.

6. The system of claim 5, wherein the selecting the first radio is further based on the first radio and the second radio being determined to satisfy a second rule related to a bounding condition.

7. The system of claim 5, wherein the selecting the first radio is further based on the first radio and the third radio being determined to satisfy a second rule related to a bounding condition.

8. A method, comprising:

determining, by a system comprising a processor, a level of geographic redundancy for a 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; and

enabling, by the system in response to a request for timed fingerprint location information, access to first timed fingerprint location information corresponding to the first radio based on the level of geographic redundancy for a first radio.
