Abstract

L'invention concerne un système et un procédé d'accès pour une architecture de classification de réseau mobile. Le procédé comprend les étapes suivantes : une fonction de commande locale envoie, lors de la réception d'une requête d'accès provenant d'un terminal, une requête de mise à jour de position à une fonction de commande globale ; et la fonction de commande globale attribue une liste de zones de suivi et un identifiant de terminal temporaire au terminal, puis envoie la liste de zones de suivi et l'identifiant de terminal temporaire à la fonction de commande locale. Le système et le procédé d'accès pour une architecture de classification de réseau mobile décrits dans la solution technique de la présente invention peuvent résoudre les problèmes d'un délai d'accès prolongé et d'une fréquente interaction de signalisation lorsqu'une signalisation d'accès dans un réseau 4G classique est transmise d'un point d'accès à un dispositif de réseau central.
