Abstract

L'invention concerne un procédé permettant de réaliser une communication sur la base d'une capacité d'UE, et un UE et un dispositif côté réseau. Le procédé comprend les étapes suivantes : un UE détermine un niveau de classification de capacité d'UE auquel il appartient ; accède à un réseau en fonction du niveau de classification de capacité d'UE déterminé, ou rapporte le niveau de classification de capacité d'UE déterminé à un dispositif côté réseau, ou accède au réseau en fonction du niveau de classification de capacité d'UE déterminé et rapporte le niveau de classification de capacité d'UE déterminé au dispositif côté réseau ; le dispositif côté réseau commande l'accès d'un UE d'un type prédéfini, l'UE du type prédéfini pouvant déterminer le niveau de classification de capacité d'UE auquel il appartient ; et/ou reçoit le niveau de classification de capacité d'UE rapporté par l'UE, et réalise un accès et/ou une planification sur l'UE sur la base du niveau de classification de capacité d'UE. La solution selon la présente invention résout le problème d'un procédé existant selon lequel une communication est effectuée sur la base d'une capacité d'équipement utilisateur (UE), celui-ci ne pouvant pas rapporter la capacité d'UE d'un UE de faible complexité de manière plus efficace, de sorte qu'un dispositif côté réseau puisse mieux identifier un UE de ce type.
