Abstract

L'invention concerne un procédé, un appareil et un système de communication destinés à être utilisés dans un réseau privé pour fournir un mécanisme de mobilité d'un dispositif terminal prenant en charge le réseau privé. Le procédé comprend les étapes au cours desquelles : un premier dispositif de réseau d'accès détermine une cellule cible dans un premier réseau cible sur la base d'une première liste, la première liste contenant au moins un identifiant d'un premier réseau signé par un dispositif terminal ; et le premier dispositif de réseau d'accès envoie un premier message à un second dispositif de réseau d'accès de la cellule cible, le premier message étant utilisé pour indiquer que le second dispositif de réseau d'accès est préparé pour commuter le dispositif terminal vers la cellule cible. Le premier message transporte une seconde liste et/ou un paramètre de vérification. La seconde liste est utilisée pour permettre au second dispositif de réseau d'accès de déterminer ledit au moins un identifiant du premier réseau signé par le dispositif terminal. Le paramètre de vérification provient du dispositif terminal et il est utilisé pour permettre au second dispositif de réseau d'accès de vérifier le dispositif terminal.
