Terminal positioning technique

摘要

A technique of estimating the location of a mobile terminal in a mobile communications network having a plurality of base stations, including: determining at least one signal parameter measurement for the mobile terminal in relation to each of the plurality of base stations; using the determined signal parameter measurements to obtain a first distance estimation of the location of the mobile terminal from each of the plurality of base stations; and using at least one estimator to obtain a positional estimation of the mobile terminal. The estimators are statistical estimators that can be applied to a distance estimation of the mobile terminal from each of the base stations and/or applied to a triangulation estimation of the actual position of the mobile terminal, based upon estimated distances of the mobile terminal from the plurality of base stations. Preferably the signal parameter measured is the Received Signal Strength.
