<p>The inventive device is used for locating one or several mobile terminals (UE1, UE2, UE3) situated in cells (C1, C2, C3) of an asynchronous mobile communications network (R) controlled by the base stations (BTS1, BTS2, BTS3), wherein said network comprises an assistance server (SA) storing time offsets of clocks of the base stations with respect to a reference clock (for example, the clock of a radio navigation satellite system CS). Said locating device (D) comprises processing means (MT) for collecting, in the case of location request from a mobile terminal (UE1), analysable signals which are received from at least two base stations (BTS1, BTS2, BTS3) and provided with a representative time stamping of a time interval selected with respect to the clock of the base stations thereof and representative data of time offsets of said base stations (BTS1, BTS2, BTS3), and to determine the position of the mobile terminal (UE1) by triangulation on the basis of the analysable signals and collected data.</p> |
