Abstract

The invention relates to a method of mobile terminal tracking, and more particularly, a method of keeping track of mobile terminals in a telecommunication system using narrow lobes for communciation between a base station (BS) and mobile stations. A first signal (a) is received from one mobile station in a main communication lobe while the base station receives a second signal (b) in another lobe. According to the invention the two signals (a, b) are compared by means of cross correlation to identify the second signal (b) as emanating from the same mobile station (A). Preferably, the signals include speech signals upon which the cross correlation is done. Thus, the invention comprises a method of identification of radio signals with different angular origin through the use of cross correlation between the unknown signal and a known signal, using the speech content of the signals only, without havign to inject any additional unique information in the signal.
