Abstract

Determining referenced based location information for a wireless radio network is described. Referenced based location information can include determining location reference information and corresponding location offset information based on location information. In an aspect, location information can be timed fingerprint location information. Location offset information can be communicated in a wireless network at a lower operational cost than the associated location information. As such, use of referenced based location information for a wireless network can reduce bandwidth consumption as compared to location information communicated at similar intervals. This is particularly true in large wireless networks. Moreover, the use of referenced based location information for determining timed fingerprint location information can be highly attractive in light of timed fingerprint location information facilitating location information for many non-GPS enabled devices and being associated with significant increases in the frequency and density of location event requests.

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;

determining a first location of a user equipment at a first time;

determining a second location of the user equipment at a second time; and

determining correlated location offset information based on the first location and the second location, wherein a difference between the first location and the second location is reflected in the correlated location offset information; and

determining compact location information comprising a first value related to the correlated location offset information, a second value related to the first location, and a third value related to a modified international mobile subscriber identity of the user equipment.

2. The system of claim 1, wherein the determining the first location is based on timed fingerprint location information.

3. The system of claim 1, wherein the determining the second location is based on timed fingerprint location information.

4. The system of claim 1, wherein the determining the correlated location offset information is based on timed fingerprint location information.

5. The system of claim 1, wherein the second value comprises latitude information related to the first location.

6. The system of claim 5, wherein the latitude information is represented by two bytes.

7. The system of claim 1, wherein the second value comprises longitude information related to the first location.

8. The system of claim 7, wherein the longitude information is represented by two bytes.

9. The system of claim 1, wherein the second value comprises altitude information related to the first location.

10. The system of claim 9, wherein the altitude information is represented by two bytes.

11. A method, comprising:

determining, by a system comprising a processor, a first a location of a user equipment at a first time;

determining, by the system, a second location of the user equipment at a second time;

determining, by the system, a set of location offset values based on the first location and the second location, wherein a change in a position of the user equipment from the first location to the second location is represented by the set of location offset values; and

determining, by the system, a set of compact location values comprising a first value related to the set of location offset values, a second value relating to the first location, and a third value related to an identification of the user equipment.

12. The method of claim 11, wherein the determining the set of location offset values is based on timed fingerprint location information.

13. The method of claim 11, wherein the second value comprises latitude information related to the first location.

14. The method of claim 13, wherein the latitude information is represented by two bytes.

15. The method of claim 11, wherein the second value comprises longitude information related to the first location.

16. The method of claim 15, wherein the longitude information is represented by two bytes.

17. The method of claim 11, wherein the second value comprises altitude information related to the first location.

18. The method of claim 17, wherein the altitude information is represented by two bytes.

19. A computer-readable storage device storing executable instructions that, in response to execution, cause a system comprising a processor to perform operations, comprising:

determining a first location and a second location of a mobile device, wherein the first location is correlated to the mobile device at a first time and the second location is correlated to the mobile device at a second time;

determining location offset information related to a difference between the first location and the second location; and

facilitating access to a compact location variable comprising a first value related to the location offset information, a second value relating to a longitude of the first location, a third value relating to a latitude of the first location, and a fourth value related to an identification of the user equipment.

20. The computer-readable storage device of claim 19, wherein the determining location offset information is based on timed fingerprint location information.
