<p>The invention relates to a method of measuring a time difference and a radio system employing the method, the radio system comprising base stations (100 to 104), terminals (114 to 116), time difference units (106 to 110) and a time difference centre (112). A real time difference RTD of the base station (100 to 104) is formed on the basis of measurements carried out by the time difference units (106 to 110) by means of an observed time difference OTD and a geometrical time difference GTD in the time difference centre (112) as a function of time, in which case the moment of occurrence of the real time difference RTD measured is connected to the real time difference RTD of the base station (100 to 104).</p> |
