System and method for mobile location by dynamic clustering

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.

1. 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, in observation space, 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, wherein the NMR represents a single vector of observed measurement information, multiple vectors of observed measurement information, or a single vector representing multiple vectors of observed measurement information.
