Device, a system, a method and computer program product for identifying interfering devices in position measurements

Abstract

A interference detection device performing the following actions: receiving individual position data from mobile terminals which individual position data indicates an area in which individual ones of the mobile terminals are located based on positioning signals received by the mobile terminals; identifying if individual position data may have been affected by one or more interfering signals transmitted by interfering device and interfering with the positioning signals; (A) identifying if a number of mobile terminals in a first area is higher than a maximum threshold number, and, if so, determining that individual position data of the number of mobile terminals may have been affected by the interfering signals; or (B) identifying if a number of the mobile terminals in a second area is lower than a minimum threshold number; and, if so, determining that individual position data of the number of mobile terminals may have been affected by interfering signals; or (C) receiving further individual position data which indicates further areas in which mobile terminals are located based on another positioning technique than a positioning technique used to determine the individual position data as received from the mobile terminals; determining if the areas overlap with the further areas at least to a minimum extent, and, if not, determining that individual position data of the mobile terminals may have been affected by the interfering signals.
