摘要： 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.

摘要： 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.

摘要： Computation of delay error offset information is facilitated. A method can include receiving measurement information indicative of a location of a mobile device, calibrating the measurement information resulting in calibrated measurement information, comparing the calibrated measurement information and historical calibrated measurement information, and computing a measurement error based, at least, on the comparing, wherein the measurement error includes delay error offset information.

摘要： 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.

摘要： 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.
