Abstract
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.
Claims20
A method of determining the geolocation of a mobile device operating in a region served by a communications network, the method comprising the steps of:
- (a) determining an observation cluster of measurement data from a first set of network measurement reports (“NMRs”) from the communication network;
- (b) comparing measurement data from a candidate NMR for a mobile device with the determined observation cluster of measurement data;
- and
- (c) determining a location of the mobile device as a function of the compared measurement information.
In a method for determining the location of a mobile device in a communications network comprising collecting calibration data having measurement information for a region in the network, the improvement comprising determining one or more clusters of measurement information from the calibration data without regard to the location where the measurement information was obtained, receiving a measurement vector for a target mobile device, comparing the measurement vector with the one or more clusters of measurement information, combining the measurement vector with a select cluster of the measurement information, and determining a location of the mobile device in the region as a function of a location corresponding to the combined measurement information.
