The invention concerns a method for communication transfer between two digital cellular radiocommunication network cells (14) and (19), wherein each of said cells comprises a set of at least two transmission and reception relays (13) geographically distributed in said cell, each of said relays capable of transmitting signals to mobile stations present in said zone, and of receiving signals transmitted by said mobile stations in said zone, a set of at least one of said relays (16) and (17) being selectively assigned to each communication with a mobile station (11), such that the signal exchanges with said mobile station (11) only concern one subpart of the cell, and, when said mobile station (11) shifts from one first cell (14) to a second cell (19), at least one parameter characterising the communication is transmitted (110) from the base station controlling said first cell (14) to the base station controlling said second cell (19), so as to ensure the continued use of said at least one parameter.
L'invention concerne un procédé de transfert de communication entre deux cellules (14 et 19) d'un réseau de radio-communication cellulaire et numérique, dans lequel chacune desdites cellules comprend un ensemble d'au moins deux relais d'émission et de réception (13) géographiquement répartis dans ladite cellule, chacun desdits relais pouvant émettre des signaux vers des stations mobiles présentes dans une zone de ladite cellule, et recevoir des signaux émis par lesdites stations mobiles dans ladite zone, un jeu d'au moins un desdits relais (16 et 17) étant sélectivement affecté à chaque communication avec une station mobile (11), de façon que les échanges de signaux avec ladite station mobile (11) ne portent que sur une sous-partie de la cellule, et, lorsque ladite station mobile (11) passe d'une première cellule (14) à une seconde cellule (19), au moins un paramètre caractérisant la communication est transmis (110) de la station de base contrôlant ladite première cellule (14) à la station de base contrôlant ladite seconde cellule (19), de façon à permettre la continuité de l'utilisation dudit au moins un paramètre.
