Abstract: A method for estimating the geographical position of a terminal of interest, among a panel of terminals of a wireless communication system. For each terminal of the panel, a time signature including values measured for each terminal during a predetermined observation period is determined. Values of similarity between the time signatures of the terminals of the panel is calculated, a similarity value calculated for two terminals representing the probability of the terminals being moved together or having been located at the same place during the observation period. Various terminals of the panel are partitioned into different groups depending on the similarity values. The geographical position of the terminal of interest is estimated as a function of the available geolocation data for at least one other terminal of the group to which the terminal of interest belongs.
