Abstract
Lorsqu'un équipement utilisateur (EU) est en mode non autonome (NSA), il peut être en communication avec des nœuds de réseau de différentes technologies d'accès radio (RAT). Par exemple, l'EU peut être en communication avec une cellule LTE 4G (par exemple, un eNodeB) et une cellule NR 5G (par exemple, un gNodeB). Mais l'EU peut perdre un service de NR lorsqu'il pénètre dans un espace où les signaux sont atténués (par exemple, un ascenseur). Sont ici divulguées des techniques pour rétablir rapidement un service de NR lorsque l'EU sort de l'espace à signal atténué.
