1. A method facilitating locating a user equipment (UE) in a wireless network, the method comprising:

  • determining, by a system including at least one processor, a set of geographical frame locations for a bin grid framework, the bin grid framework having a predetermined granularity;

    determining, by the system, a set of NodeB site pairs (NBSPs) comprising a first NodeB site and a second NodeB site, wherein locations of the first NodeB site and the second NodeB site are known;

    determining, by the system, a set of reference frames, wherein the set of NodeB site pairs respectively have at least one reference frame having a known location;

    accessing, by the system, a first time value (OV(1)) for a first frame of the bin grid framework correlated to a first known geographic frame location of the geographic frame locations;

    accessing, by the system, location information of the first frame for the first known geographic frame location;

    determining, by the system, a first differential value (DV(1)) for the first frame, related, at least in part, to a difference between the location information of the first frame and location information of a first NodeB site pair of the set of NodeB site pairs;

    accessing, by the system, location information for a first reference frame correlated to the first NodeB site pair;

    determining, by the system, a second differential value (DV(2)) for the first reference frame, related, at least in part, to a difference between the location information of the first reference frame and the location information of the first NodeB site pair; and

    determining, by the system, a second time value (OV(2)) based, at least in part, on OV(1), DV(1), and DV(2).
