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 correlated location offset information based on a change in a location of a user equipment from a first location to a second location; and

determining a representation of the second location comprising an offset value related to the correlated location offset information, a start value related to the first location, and an identifier value resulting from modifying an international mobile subscriber identity of the user equipment, wherein the modifying comprises removing at least one digit of an international mobile subscriber identity number of the user equipment.

2. The system of claim 1, wherein the first location is determined from timed fingerprint location information.

3. The system of claim 1, wherein the second location is determined from 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 start value comprises latitude information related to the first location.

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

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

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

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

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

11. A method, comprising:

determining, by a system comprising a processor, location offset values representing movement of a user equipment from a first location to a second location; and

determining, by the system, compact location values comprising a first value related to the location offset values, a second value relating to the first location, and a third value related to an identification of the user equipment comprising a truncated international mobile subscriber identity of the user equipment resulting from removing at least the mobile country code from an international mobile subscriber identity number corresponding to the user equipment.

12. The method of claim 11, wherein the determining the 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 at least 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 at least 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 at least two bytes.

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

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

enabling access to a location value associated with the second location, wherein the location value comprises an offset value related to the location offset information, a base value relating to the first location, an identity value relating an identification of the user equipment comprising a modified international mobile subscriber identity of the user equipment resulting from removing a portion of an international mobile subscriber identity number assigned to the user equipment.

20. The non-transitory machine-readable storage medium of claim 19, wherein the modified international mobile subscriber identity is represented by at least two bytes.
