摘要： A system and method for determining the location of a target mobile device in a communications network. A set of mobile devices in proximity to the target mobile device may be determined as a function of a common parameter of information observed by mobile devices in the set. Measurement data may be shared for the set of mobile devices and the target mobile device, and a location of the target mobile device determined as a function of the shared measurement data. This sharing of measurement data may occur amongst the set of mobile devices and the target mobile device or may also occur at a communications network entity.

摘要： A method of modifying calibration data used to geo-locate a mobile station located in an indoor environment is disclosed. When a mobile station is located indoors, the signal strength of signals received and/or transmitted by the mobile station have the tendency to be lower than the strength of the signals received by a mobile station located outdoors. As a result of these lower signal strengths, geo-location efforts which rely on signal strengths may result in unsatisfactory location accuracy. Modifying pre-existing calibration data obtained outdoors may provide a way to simulate indoor calibration data characteristics.

摘要： A system and method for estimating the location of a mobile station that receives signals from a plurality of base stations. The base station timing offsets may be estimated utilizing an observed time difference of arrival value at the mobile between a first signal received from a first base station and a second signal received from a second base station. An initial location for the mobile is randomly selected and an estimated location is determined using the selected initial location, the observed time difference of arrival value, and an iterative search algorithm. The estimated location may be stored if the estimated location is within a predetermined area. In addition, for each such estimated location, the applicable base station time offsets that relate to this location may be updated to generate a current best estimate. A calculated location for the mobile may be determined from stored estimated locations and the current base station time offset estimates.

摘要： A system and method to re-calibrate an area of a wireless communications network that has been exposed to one or more network configuration changes is disclosed. When one or more attributes of the wireless network undergo a change which impairs the geo-location capability to locate a mobile station, it can be detrimental to the safety and well being of the network users. Geo-location calculations rely on accurate and updated calibration data to correctly locate a mobile station. In some instances, it may be necessary to update the calibration data for areas of the network that have been exposed to network configuration changes. Modifying previously collected calibration data to account for changes that have occurred in the network may increase the accuracy of mobile station location estimation.

摘要： A method and system for estimating the location of a mobile device. A range of the mobile device to a reference station may be determined as a function of the time of transmission of a first signal transmitted from a base station and as a function of the time of receipt of a second signal transmitted from the mobile device to the reference station, the second signal being a function of the first signal advanced by a timing parameter. A relationship for each of a plurality of grid points in a geographic region may be determined as a function of the determined range and a range metric. These plural grid points may contain the reference station. The determined relationship may be compared with data corresponding to each of the plural grid points, and a location of the mobile device determined as a function of the comparison.

摘要： The location of a wireless mobile device may be estimated using, at least in part, one or more pre-existing Network Measurement Reports (“NMRs”) which include calibration data for a number of locations within a geographic region. The calibration data for these locations is gathered and analyzed so that particular grid points within the geographic region can be determined and associated with a particular set or sets of calibration data from, for example, one or more NMRs. Received signal level measurements reported by a mobile device for which a location estimate is to be determined may be compared with the data associated with the various grid points to estimate the location of the mobile device.

摘要： A system and method of applying a known modification in the form of a distortion to a signal to enable a determination if a signal received by a first node is received directly from a second node or indirectly through a repeater. The repeater receives a primary signal and creates a secondary signal as a function of the primary signal and a known distortion, wherein the known distortion identifies the repeater. The primary signal is transmitted and injected with the secondary signal as the first signal to the primary receiver.

摘要： A method for calibrating an antenna and signal processing system enabling angle of arrival (AOA) determination for a frequency hopping signal, in which a calibration coefficient is determined in response to one or more calibration signals injected into the system at one or more of the frequencies in the hopping sequence and proximate in time to reception of the communication signal. The calibration coefficients are reflective of a frequency and time dependent parameter of a path between the antenna and wireless location sensor. The AOA is determined as a function of the calibration coefficient and the radio frequency energy of the received communication signal. Several embodiment of the method are illustrated.
