Abstract:
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; determining, by the system, a frame data value set comprising computed differential values for the set of NodeB site pairs and sets of frames within a predetermined distance from NodeB site pairs, wherein the computed differential values are related, at least in part, to respective differences between respective locations of respective frames of the sets of frames and locations of a relevant NodeB site pair, wherein the relevant NodeB site pair is a NodeB site pair within the predetermined distance; accessing, by the system, a first time value (OV( determining, by the system, a first differential value (DV( accessing, by the system, a second time value (OV( determining a lookup value based at least in part on OV( accessing, by the system, a first subset of frames for a search through the frame data value set, the accessing including searching for frames correlated to the lookup value and a NodeB site pair of the set of NodeB site pairs.
