Abstract
There is provided a solution for detecting and filtering inaccurate measurement results used for positioning a mobile device. A method comprises as performed by an apparatus: determining locations of a plurality of fixed positioning nodes; receiving a measurement report from a mobile device, the measurement report comprising a plurality of measurement values measured by the mobile device, wherein each measurement value comprises a reference signal time difference indicating a radio propagation time difference between the mobile device and two different positioning nodes; determining, on the basis of threshold comparison, that at least one of the plurality of measurement values is associated with an inaccurate measurement; modifying, autonomously by the apparatus, said at least one of the plurality of measurement values; and computing a location of the mobile device on the basis of a plurality of measurement values resulting from said modifying.
