Abstract
Un transfert intercellulaire avec agrégation de porteuses est fourni. Un procédé permettant d'assister un transfert intercellulaire d'un équipement utilisateur depuis un nud d'accès sans fil source jusqu'à un nud d'accès sans fil cible, destiné à un réseau d'accès sans fil ayant une pluralité de fréquences porteuses et une pluralité de cellules dans lequel une cellule et une fréquence porteuse peuvent être configurées sous la forme d'une porteuse de composantes, et dans lequel au moins deux porteuses de composantes peuvent être agrégées pour une communication entre l'équipement utilisateur et le nud d'accès sans fil source, les porteuses de composantes agrégées comprenant une porteuse de composantes primaire et au moins une porteuse de composantes secondaire inclut les étapes suivantes consistant à sélectionner, au niveau du nud d'accès sans fil source, une première fréquence porteuse qui doit être configurée comme une porteuse de composantes primaire pour une communication avec le nud d'accès sans fil cible après un transfert intercellulaire, et sélectionner, au niveau du nud d'accès sans fil cible, un deuxième fréquence porteuse qui doit être configurée comme une porteuse de composantes secondaire pour une communication avec le nud d'accès sans fil cible après un transfert intercellulaire.
