METHOD FOR POSITION DETERMINATION

摘要

The invention relates to a method for determining the position of a mobile station (MS1) in a mobile telephony system comprising a plurality of base stations (BS1, BS2, BS3 and BS4). According to the inventive method, the position of a mobile station (MS1) is requested, and is determined by measuring the transit times of at least one first and one second signal transmitted from at least one first and one second base station to said mobile station. The transit time of at least one other signal transmitted from the first base station to the mobile station and/or from the second base station to the mobile station is measured for each position request. Preferably, the number of transit time measurements is determined according to the local environment (C) of the mobile station (MS1).
