Abstract

L'infrastructure comporte un coeur de réseau, des contrôleurs de réseau radio reliés au coeur de réseau et des stations de base pourvues d'interfaces radio et reliées chacune à l'un des contrôleurs. De l'information chiffrée est transmise sur un premier chemin de communication en mode circuit entre le coeur de réseau et le terminal, passant par un premier contrôleur maître, puis sur un second chemin de communication en mode circuit entre le coeur de réseau et le terminal, passant par un second contrôleur maître. Le second chemin est établi dans une procédure de transfert comprenant la transmission de données de réglage du premier au second contrôleur maître et la suppression du premier chemin. Ces données sont représentatives d'une valeur courante d'un numéro de séquence utilisé pour chiffrer l'information et incrémenté à intervalles réguliers, et d'un décalage entre ce numéro de séquence et une référence de temps disponible au second contrôleur.
