| description | The invention relates to a method of measuring a time difference and a radio system employing the method, the radio system comprising base stations, terminals, time difference units and a time difference centre. A real time difference RTD of the base station is formed on the basis of measurements carried out by the time difference units by means of an observed time difference OTD and a geometrical time difference GTD in the time difference centre 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. |
