摘要： A system and method selects secondary base stations to task that provide geo-location information used to geo-locate a mobile station. A network overlay location system may be co-located at base station sites of a wireless communications network. The location measurement units of the network overlay system provide location information of the mobile station, which may be determined via one or more geo-location techniques, for example: time of arrival (TOA), time difference of arrival (TDOA), uplink time difference of arrival (UTDOA), angle of arrival (AOA), signal power, radio fingerprinting etc. Selecting secondary base stations to task using various selection criteria may provide optimum results when geo-locating a mobile station.

摘要： A method and apparatus for estimating a location of a device. For each of a plurality of locations of a device, a set of positional data is determined from signals received from a plurality of satellites. The positional data is filtered and compared with data from a road network database. This comparison may be a function of a distance from at least one point defined by a set of the filtered positional data to a road in the road network database and an angle between a line representing a best fit for plural points defined by corresponding plural sets of the filtered positional data to a line defined by a road in the road network database.

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 calibration 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. Sets of calibration points may be evaluated as a function of parameters of the calibration data, and a set of calibration points may be selected as a function of a predetermined criteria. Signal reception in the region may be estimated as a function of mobile device location in the region and an approximate statistical accuracy of a signal strength pattern determined as a function of the estimated signal reception. An expected accuracy of a location system may then be modeled in the region as a function of system configuration information and determined approximate statistical accuracy.

摘要： A method and system for determining the location of a mobile appliance in a communications system having a plurality of nodes. The plurality of nodes are tasked to measurement the time of arrival (TOA) of the signal transmitted by the mobile appliance in an assigned time slot across multiple frames of data. TOA measurement data may be derived from ones of the multiple frames of data where the derived TOA measurement data is non-coherently integrated across the ones of the multiple frames of data. A location estimate of the mobile appliance may then be determined as a function of the derived TOA measurement data.

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. Embodiments of the present subject matter also provide a method of improving a location estimate of a mobile device. Received signal level measurements reported by a mobile device for which a location estimate is to be determined may be evaluated and/or compared with the characteristics associated with the various grid points to estimate the location of the mobile device.

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.
摘要翻译：公开了一种修改用于对位于室内环境中的移动台进行地理定位的校准数据的方法。当移动台位于室内时，由移动台接收和/或发送的信号的信号强度倾向于低于由位于室外的移动台接收到的信号的强度。由于这些较低的信号强度，依靠信号强度的地理定位工作可能导致不能令人满意的定位精度。修改户外获得的现有校准数据可以提供一种模拟室内校准数据特性的方法。
