Abstract: Detection of a confusion caused by scrambling code reuse is provided herein. Timing measurements, as observed by a mobile device, and an identification of primary scrambling codes associated with the timing measurements are captured. The timing measurements are identified by the primary scrambling codes for the particular radio measured. The mobile device also reports its location information. Radios for which timing measurements have been received are paired. Based on the paired radios and a history of observed time difference reference values for radio pairs, comparisons are made between paired radios having at least one common radio. Radios, exhibiting a set of values that is near an expected range, are removed from the analysis. Radios, exhibiting two sets of values that are distinct, are isolated in order to identify the radio that is causing the scrambling code confusion.

Abstract: Systems and techniques for determining the location of user equipment (UE) in a wireless network are disclosed. These techniques leverage geometric calculations for an overlaid local bin grid framework mapping an area of a wireless network to stored differential values for each frame of the local bin grid framework for pairs of relevant NodeB radios. A timing offset can be determined, such that when a time value from the UE is accessed, the location can be quickly determined with minimal real time computation. In an aspect, the UE time value can be searched for in the pre-computed differential value data set indexed by a relevant NodeB radio pair to return a set of frames that can be intersected with a second set of frames for a second NodeB radio pair for the UE. The intersecting frames can represent the location of the UE in the wireless network.

Abstract: Systems and techniques for determining the location of user equipment (UE) in a wireless network are disclosed. These techniques leverage geometric calculations for an overlaid bin grid framework mapping the wireless network area to store differential values for each frame of the bin grid framework for each pair of relevant NodeBs. A timing offset can be determined, such that when a time value from a target UE is accessed, the location can be quickly determined with minimal real time computation. In an aspect, the time value from an idle-state target UE can be accessed. The target UE time value can be searched among pre-computed differential value data sets indexed by relevant NodeB site pairs to return sets of frames that can facilitate converging on a location for the target UE. Intersecting frames can represent the geographic location of the UE in the wireless network. Further, the data can be leveraged to correct timing in the network.

Abstract: The systems and methods disclosed herein can implement a handset agent calibration solution that uses the GPS receivers on mobile devices to determine a location of the mobile device to calibrate timing based locating systems. The handset agent can be installed on the mobile device and can upload to an internet server the coordinates captured by the GPS receiver along with the observed time differences. The observed time differences and the location of the mobile device can be used to solve for reference time differences to calibrate unsynchronized macrocells. The reference time difference can be used to solve for the location of other mobile devices if the observed time differences between that mobile device and the macrocells are known. The solution can include receiving measurement reports from many mobile devices to obtain averaged observed time differences at a reference location to achieve more accurate reference time differences.

Abstract: Adaptive calibration of measurements for a wireless radio network is described. A network location system can employ timed fingerprint location technology to determine location information for UEs in a NELOS enabled wireless network environment. Calibration of observed time measurements can reduce errors in determining location information. Adaptive calibration facilitates the selection of subsets of wireless network radios for calibration updates. The selection of wireless network radios comprising the subsets can be based on prioritization rules including prioritization based on historical calibration information, geographic information, or observation density information for a wireless network radio. Further, a wireless network radio can be deprioritized based on the availability of alternate location information related to the wireless network radio.

Abstract: Downlink signal strength measurements from base stations (BSs) are reported by mobile devices to facilitate mobile device locating. A system receives the signal strength information and determines whether the mobile device is within a selected distance from any of the BSs in response to detecting that signal strength information for one of the BSs is greater than a predefined value. The system determines an area over which to search for the mobile device if the system fails to detect that the signal strength information for any of the BSs is greater than the predefined value. The area over which the search is performed is an intersection of all regions determined by the signal strengths of the BSs.

Abstract: Systems and techniques for determining the accuracy of network based user equipment (UE) locating methods and results thereof are disclosed. Periodic direct measurements of location error for a network based location result are determined by the difference in the network based location result and an assisted global positioning system (AGPS) location result. The location error is associated with a cell-pair contributing to data employed to determine the network based location result. The error associated with the cell-pair is then applied as a measure of accuracy in future network based location results that also employ data associated with the cell-pair to determine the future network based location result.
