Abstract  Abstract

The invention relates to a method for measuring the time difference and using the method of wireless system the wireless system comprising a base station (100 to 104) the terminal (114 116) a time unit (106 to 110) and time (112). The measure of difference unit (106 to 110). time difference centre (112) using an observed time difference OTD and the geometrical time difference GTD generating time varying real time difference RTD of base station (100 to 104) in which case the real time difference RTD of the real time difference RTD measured by the appearance time and the base station (100 to 104).

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).
