Abstract

Les modes de réalisation de la présente invention concernent un procédé et un appareil de sélection de cellule, qui peuvent être appliqués à des systèmes tels que l'Internet des véhicules. Le procédé consiste à : déterminer si un dispositif terminal est un dispositif terminal embarqué ; et selon le résultat de la détermination du fait que le dispositif terminal est un dispositif terminal embarqué, le dispositif terminal sélectionne une cellule associée à un nœud de liaison d'accès et retour intégrés (integrated access backhaul / IAB). Au moyen de la mise en oeuvre des modes de réalisation de la présente demande, une priorité de fréquence n'est pas prise en considération pendant une sélection de cellule ou une resélection de cellule, une cellule associée à un nœud IAB mobile correspondant est sélectionnée en fonction de l'état de mouvement d'un dispositif terminal, et une cellule associée à un nœud IAB statique correspondant est sélectionnée en fonction de l'état statique du dispositif terminal, ce qui permet de réduire efficacement le nombre de resélections de cellule.
