Abstract
The invention proposes a method for locating a network element, comprising the steps of obtaining (S) the coordinates (xS, yS) of a second network element (BTS) to which the first network element (MS) is connected or attached; detecting (S) a serving area (S), which is served by the second network element (BTS); detecting (S) a propagation delay of the first network element with respect to the second network element (BTS); determining (S) a propagation delay depending area (C), which is an area having a distance to the second network element (BTS) based on the propagation delay and a width based on the propagation delay; and forming (S) an intersection area (I) of the serving area (S) and the propagation delay depending area (C); wherein a location estimate of the first network element (MS) is determined (S) from the intersection area (I). Thus, an uncertainty area where a first network element is located can be reduced and the location accuracy can be improved.
