A method and devices are provided for adapting the transmission power level of a mobile terminal during a handover phase at which the mobile terminal switches from one base station to another. The method provided comprises applying values of operating parameters that characterize both base stations and adapting the transmission power level to an acceptable level at which communications transmitted from the terminal to the second station would be properly received without applying further increase in the transmission power while ensuring that the communications transmitted by the mobile terminal to the second base station, will not cause severe interference to communications exchanged between the second base station and the other terminals communicating therewith.
L'invention concerne un procédé et des dispositifs permettant d'adapter le niveau de puissance de transmission d'un terminal mobile pendant une phase de transfert intercellulaire lors de laquelle le terminal mobile passe d'une station de base à une autre. Le procédé de l'invention consiste à appliquer des valeurs de paramètres de fonctionnement qui caractérisent les stations de base et à adapter le niveau de puissance de transmission à un niveau acceptable auquel les communications transmises du terminal à la deuxième station de base pourraient être reçues correctement sans augmenter davantage la puissance de transmission tout en assurant que les communications transmises par le terminal mobile à la deuxième station de base ne provoquent pas d'interférences notables sur des communications échangées entre la deuxième station de base et les autres terminaux en communication avec celle-ci.
