Abstract

L'invention concerne un procédé et un dispositif de communication. Le procédé de communication comprend les étapes suivantes : un dispositif de réseau détermine un état de congestion d'une première cellule à laquelle accède à un dispositif terminal ; et le dispositif de réseau envoie des premières informations d'instruction au dispositif terminal si l'état de congestion de la première cellule respecte une première condition prédéfinie, les premières informations d'instruction étant utilisées pour empêcher le dispositif terminal d'envoyer au dispositif de réseau une première demande d'accès pour la première cellule dans une première période de temps. Dans le cas d'une congestion de réseau, des informations, pour empêcher un dispositif terminal de réaccéder au réseau pendant une durée spécifiée après que les ressources ont été libérées par le réseau, sont envoyées au terminal qui a accédé au réseau, de sorte que le réseau évite davantage de congestion en raison du réaccès au réseau par le dispositif terminal, ce qui permet de réduire la congestion du réseau.
