A mobile communication system performs handoff taking into consideration a travelling direction of a mobile station. A mobile station measures strengths of pilot signals from base stations adjacent thereto and transmits information about the measured strengths to a BSC. The BSC then selects one of the base stations as a handoff target base station depending on the measured strength information and location information of the mobile station and the base stations. The weights are applied to the adjacent base stations according to directions of the adjacent base stations based on a travelling direction of the mobile station, which is predicted according to movement of the mobile station.
L'invention porte sur un système mobile de télécommunications prenant en considération la direction du déplacement d'un poste mobile. Le poste mobile mesure l'intensité de signaux pilotes émis par des stations de base voisines et transmet à un contrôleur de station de base des informations sur les intensités mesurées. Le contrôleur de station de base sélectionne alors l'une des stations de base comme station cible de transfert en fonction des informations sur les intensités mesurées et d'informations sur la position du poste mobile et des stations de base. Des pondérations sont appliquées aux stations de base voisines en fonction de leurs directions par rapport la direction de déplacement du poste mobile prédite d'après son mouvement.
