Abstract

La présente invention concerne un procédé d'obtention d'un type de réseau central, un dispositif de réseau d'accès et un dispositif de réseau central. Un dispositif de réseau d'accès peut obtenir directement un type de réseau central au lieu d'obtenir le type de réseau central à l'aide d'un rapport ANR pendant un transfert intercellulaire, ce qui permet de résoudre le problème de retard provoqué par le rapport ANR. Le procédé comprend les étapes suivantes consistant : à envoyer, par un premier dispositif de réseau d'accès, un message de requête à un second dispositif de réseau d'accès, le message de requête comprenant une identité de cellule globale (GCI) d'une cellule voisine cible d'une cellule desservie par le premier dispositif de réseau d'accès, et le message de requête étant utilisé pour demander un type de réseau central de la cellule voisine cible ; à desservir, par le second dispositif de réseau d'accès, la cellule voisine cible ; à recevoir, par le premier dispositif de réseau d'accès, le type de réseau central de la cellule voisine cible renvoyé par le second dispositif de réseau d'accès par rapport au message de requête.
