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 memory to store executable instructions; and

a processor, communicatively coupled to the memory, that facilitates execution of the executable instructions to performions comprising;

receiving location information related to a location of a user equipment; and

determining location reference information and corresponding location offset information based on the location information, wherein changes in the location of the user equipment are related to corresponding changes in the location offset information, the location offset information comprises an identification parameter related to an identification of the user equipment.

2. The system of claim 1, wherein the location information comprises timed fingerprint location information.

4. The system of claim 1, wherein the identification parameter is a modified international mobile subscriber identity parameter.

5. The system of claim 4, wherein the modified international mobile subscriber identity parameter is four (4) bytes.

6. The system of claim 5, wherein the modified international mobile subscriber identity parameter excludes the mobile country code and the mobile network code.

7. The system of claim 1, wherein the location offset information further comprises a timestamp parameter related to a time value and the timestamp parameter is one (1) byte.

8. The system of claim 1, wherein the location offset information further comprises a location parameter related to the location of the user equipment and the location parameter comprises a longitude parameter, a latitude parameter, and an altitude parameter.

9. The system of claim 8, wherein the longitude parameter is two (2) bytes, the latitude parameter is two (2) bytes and the altitude parameter is two (2) bytes.

10. The system of claim 1, wherein the location offset information further comprises a method parameter related to another identification of a location method and an accuracy parameter related to a further identification of a level of accuracy.

11. The system of claim 10, wherein the method parameter is four (4) bits and the accuracy parameter is four (4) bits.

3. (canceled)

12. A method, comprising:

receiving, by a system including a processor, location information relating to a location of a user equipment; and

determining, by the system, a set of location reference values and a set of location offset values based on the location information, wherein changes in the location of the user equipment are related to corresponding changes in the set of location offset values, and the set of location offset values comprise an identification parameter related to an identification of the user equipment.

13. The method of claim 12, wherein the receiving the location information includes receiving timed fingerprint location information.

15. The method of claim 12, wherein the determining the identification parameter includes determining a modified international mobile subscriber identity parameter.

16. The method of claim 15, wherein the determining the international mobile subscriber identity parameter includes determining the international mobile subscriber identity parameter excluding the mobile country code and the mobile network code.

17. The method of claim 12, wherein the determining the set of location offset values further comprises determining a location parameter related to identifying the location of the user equipment and comprising a longitude parameter, a latitude parameter, and an altitude parameter.

18.
