Abstract

Method to reciprocally synchronize at least one pair of base stations (1, 2) belonging to a digital telecommunication network, in which the radio signals transmitted and received by said stations (1, 2) are subdivided into frames having pre-set duration and each frame is subdivided into a pre-set number of time slots including at least one field destined to the transmission of frame synchronization data (T1, T2), characterized in that it includes the following operating steps: transmitting by said pair of stations (1, 2) a radio signal containing at least its own frame synchronization data (T1, T2); receiving by said pair of stations (1, 2) the frame synchronization data (T2, T1) transmitted by the other station (2, 1); calculating by said pair of stations (1, 2) the phase shift values (D12, D21) between its own frame synchronization data (T1, T2) and the frame synchronization data (T2, T1) received by the other station (2, 1); introducing a time delay or advance, according to the sign, in at least one of the frame synchronization data (T1, T2) of said pair of stations (1, 2) said time delay or advance having a duration in absolute value essentially equal to one half of the difference between said phase shift values (D12, D21). The present invention relates also to a system implementing this method.
