Cellular telecommunication network (1) comprises a plurality of base station (4, 6, 7) together with a plurality of positioning elements (3, 5). In order to position mobile station (2), positioning signals are transmitted from positioning elements (3, 5) and can be detected by mobile station (2). By detecting the time of arrival of the positioning signals, the network (1) can determine the position of mobile station (2). |
