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 system and method for determining the location of a mobile device in a communications network. A set of network measurement reports (NMR) may be provided for a region in the network. NMRs in the first set may be clustered as a function of observed measurement information in the NMRs. A candidate NMR for a mobile device may be received, and the candidate NMR may then be associated with a selected cluster of NMRs. The candidate NMR and a second set of NMRs may then be clustered, and a location of the mobile device determined as a function of the clustered candidate NMR and second set of NMRs, where the NMRs in the second set are associated with the selected cluster.
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:
A system and method for determining the location of a mobile device. One or more location measurement units (LMUs) or components may be requested to provide timing relationship information from a respective cell site. These LMUs may then be tasked to measure uplink times of arrival of signals received by the LMUs from a target mobile device. A response message from the target mobile device may be received, the response message having reference epoch frame information whereby a Global Positioning System (GPS) time estimate at the reference epoch that the target mobile device used to make GPS satellite measurements is determined as a function of the requested timing relationship information. Satellite information may then be determined using the determined GPS time estimate, and a location of the mobile device performed using this satellite information.
摘要:
A method of determining the location of a mobile device in a communications network having a plurality of nodes, one of the plural nodes serving the device. Observed positioning measurements for a mobile device may be received from the serving node and uplink enhanced cell identification (E-CID) positioning measurements received from the mobile device. One or more ranges between ones of the plural nodes and the mobile device may then be determined as a function of the received observed positioning measurements and the received uplink E-CID positioning measurements. A geographic location of the mobile device may then be estimated as a function the determined one or more ranges.
