Abstract

L'invention concerne un procédé et un appareil de communication, et un dispositif. Le procédé comprend les étapes consistant à : recevoir un premier message envoyé par un dispositif côté réseau, le premier message comprenant des informations auxiliaires cibles, les informations auxiliaires cibles étant utilisées pour représenter des informations d'identification d'un nœud de réseau, et le nœud de réseau comprenant un satellite cible ou une cellule cible ; et en fonction des informations auxiliaires cibles, mesurer un signal du nœud de réseau après l'ajustement d'un angle d'antenne ou commuter vers le nœud de réseau après l'ajustement de l'angle d'antenne. Selon des modes de réalisation de la présente demande, un retard pendant un processus de commutation ou un processus de resélection de cellule d'un dispositif terminal peut être réduit, ce qui permet de réduire le risque que le dispositif terminal soit déconnecté d'un réseau, et d'améliorer ainsi l'expérience de continuité d'un service du dispositif terminal.
