The aim of the invention is to adapt the timing advance of a mobile terminal (MS) during synchronous handover from a first (BS1) to a second base station (BS2) of a radio communications system. To this end a time delay (.DELTA.t, .DELTA.ta, .DELTA.td) between time standard (N1, 2, N2a, N2d) received by the terminal from the two base stations are measured. A timing advance value (TA1) that is used by the terminal (MS) prior to handover for transmission to the first base station (BS1) is corrected using the time delay measured. The corrected timing advance value is reduced by a value (2Gsync) derived from the accuracy (Gsync) of the synchronicity of the two base stations (BS1, BS2) and is used as the timing advance value (TA2) for transmission to the second base station (BS2).

En vue de l'adaptation de l'avance temporelle d'un terminal mobile (MS) lors du transfert synchrone d'une première (BS1) à une deuxième station de base (BS2) d'un système de communication par radio, un décalage temporel (.DELTA.t, .DELTA.t¿a?, .DELTA.t¿d?) est mesuré entre des références de temps (N1, N2, N2a, N2d) que le terminal reçoit des deux stations de base, et une valeur d'avance temporelle (TA1) utilisée par le terminal (MS) avant le transfert et destinée à être envoyée à la première station de base (BS1) est corrigée à l'aide du décalage temporel mesuré. La valeur d'avance temporelle corrigée est réduite d'une valeur (2Gsync) dérivée de la précision (Gsync) de la synchronicité des deux stations de base (BS1, BS2) et utilisée en tant que valeur d'avance temporelle (TA2) destinée à être envoyée à la deuxième station de base (BS2).
