Publication number: 20150148059Abstract: Techniques for locating a mobile device using a time distance of arrival (TDOA) method with disturbance scrutiny are provided. In an aspect, for respective combinations of three base station devices of a number of base station devices greater than or equal to three, intersections in hyperbolic curves, generated using a closed form function with input values based on differences of distances from the device to pairs of base station devices of the respective combinations of three base station devices, are determined. The intersection points are then tested for robustness against measurement errors associated with the input values and a subset of the intersection points that are associated with a degree of resistance to the measurement errors are selected to estimate a location of the device.Type: ApplicationFiled: November 26, 2013Publication date: May 28, 2015Applicant: AT&T Intellectual Property I, L.P.Inventors: Sarat Puthenpura, Jie Chen, Sam Houston Parker, Huahui Wang, Wenjie Zhao

Patent number: 8886219Abstract: A location of user equipment (UE) in a wireless network is determined. Geometric calculations are leveraged 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. The target UE time value can be searched for in the pre-computed differential value data set indexed by a relevant NodeB site pair to return a set of frames (forming a hyperbola between the site pair) that can be intersected with a second set of frames for a second NodeB site pair for the same UE. The intersecting frames can represent the location of the UE in the wireless network and timing in the network is correctable based on the data.Type: GrantFiled: June 25, 2013Date of Patent: November 11, 2014Assignee: AT&T Mobility II LLCInventors: Sheldon Meredith, Mark Austin, Jeremy Fix, Wenjie Zhao, Sarat Puthenpura
