Abstract

L'invention concerne un procédé de transfert de terminal interurbain, à l'état de réception. Selon ce procédé, il est prévu de : détecter l'intensité du signal provenant de la SB de la cellule source et de la cellule cible par le terminal interurbain, à l'état de réception, et déterminer si la condition de début de transfert est satisfaite. Dans l'affirmative, déterminer si la cellule cible est le groupe interurbain d'appui auquel le terminal interurbain appartient. Si tel est le cas, contrôler l'information de canal aller partagé du terminal interurbain, transmise par la cellule cible et effectuer directement le transfert entre le canal aller partagé de la cellule source et le canal aller partagé de la cellule cible du terminal interurbain. Si la condition n'est pas remplie ou n'est pas soutenue, le terminal met fin au transfert, en continuant d'utiliser le canal aller partagé de la cellule source. Pendant le transfert, il n'est pas nécessaire d'utiliser la signalisation de commutation entre les équipements côté réseau et la SB n'a pas à rétablir le canal de service sans fil. L'invention permet d'économiser les ressources sans fil du système et de simplifier la procédure de transfert du terminal interurbain, à l'état de réception.
