Abstract

La présente invention concerne un procédé de gestion de la mobilité qui consiste à: lancer un flux de migration assistée ou de transfert sur une cellule cible commandée par un premier contrôleur de réseau radio (RNC) d'un contrôleur de réseau radio relais (DRNC) (101); si la cellule cible commandée par le premier RNC a commuté sur un RNC de secours de DRNC, recevoir un accusé de réception de défaillance renvoyé par le premier RNC, ledit accusé de réception de défaillance contenant des informations de la cellule cible commandée par le RNC de secours ou des informations d'indication permettant d'obtenir des informations de la cellule cible commandée par le RNC de secours (102); lancer une migration assistée ou un transfert sur la cellule cible commandée par le RNC de secours en fonction des informations de cellule cible ou des informations d'indication (103). La présente invention concerne également un dispositif réseau, un RNC et un système de communication.
