1. A system, comprising:

  • a memory to store executable instructions; and

    a processor, coupled to the memory, that facilitates execution of the executable instructions to perform operations, comprising;

    determining a location of a user equipment based on a first device timing measurement associated with the user equipment, a second device timing measurement associated with the user equipment, and stored timed fingerprint location information, wherein the stored timed fingerprint location information is based on a first differential timing measurement for a NodeB site pair comprising a first NodeB device and a second NodeB device and a second differential timing measurement for another NodeB site pair comprising a third NodeB device and a fourth NodeB device, wherein the first differential timing measurement is correlated to a first set of location information for a first hyperbola shaped geographic location region and the second differential timing measurement is correlated to a second set of location information for a second hyperbola shaped geographic location region, each determined before the stored timed fingerprint location information is stored, and wherein the first and second sets of location information and the first and second differential timing measurements are stored as part of the stored timed fingerprint location information to facilitate determining the location of the user equipment based on querying the stored timed fingerprint location information to determine an overlap location region between the first hyperbola shaped geographic location region and the second hyperbola shaped geographic location region based on the first and second device timing measurements and the first and second differential timing measurements without redetermining the first and second hyperbola shaped geographic location regions; and

    determining a compliance status for a location analytics rule based on the location of the user equipment.
