Abstract
The invention relates to a method for computing the geographical location of a mobile terminal (MT) in a cellular telecommunications network. The method includes the steps of collecting identifiers of possible serving cells for the mobile terminal, selecting from a first database (A) geographical coordinates (LONG, LAT) whose expected serving cell ID matches any one of the identifiers of possible serving cells, comparing, for each selected geographical coordinate (LONG, LAT), pairs of cell identifiers and corresponding expected received signal values associated with the geographical coordinate (LONG, LAT) in the first database (A) with pairs of cell identifiers and corresponding actual received signal values of the possible serving cells to determine the geographical locations (LONG, LAT) having a number of matches (NMATCH) greater than a predetermined match threshold (THRESHOLD-NMATCH) and finally processing the geographical locations so determined (LONG, LAT) to obtain the geographical location of the mobile terminal (MT).
