Abstract

L'invention concerne un dispositif, un système et un procédé de mise à jour de zone de suivi. Un équipement utilisateur, en tant que dispositif de mise à jour de zone de suivi, acquiert des premières informations, les premières informations étant utilisées pour déterminer un temps d'attente ; si il est déterminé qu'un processus de mise à jour de zone de suivi doit être effectué, un module de traitement est en accord avec les premières informations, et l'équipement utilisateur détermine le temps d'attente ; et après avoir attendu pendant le temps d'attente, l'équipement utilisateur envoie un message de demande de mise à jour de zone de suivi à un dispositif de réseau principal en tant que dispositif de mise à jour de zone de suivi. Sur cette base, pour un équipement utilisateur (UE) se déplaçant à une vitesse élevée, tel qu'un UE qui effectue des communications dans les conditions d'un train à grande vitesse, chaque UE est configuré pour attendre un certain temps avant d'effectuer un processus de mise à jour de zone de suivi, ce qui permet d'éviter une tempête de signalisation provoquée lorsqu'un UE déclenche de manière intensive un processus de mise à jour de zone de suivi dans un court laps de temps, ce qui permet d'éviter l'encombrement du réseau.
