Abstract

Des modes de réalisation de la présente demande concernent un procédé de communication sans fil, un dispositif terminal, et un dispositif de réseau. Un terminal dans un état inactif RRC peut déterminer une période pour obtenir une instruction de mise à jour de message système et un message système mis à jour, de façon à optimiser la transmission du message de système. Le procédé de communication sans fil comprend l'étape suivante : un dispositif terminal obtient une instruction de mise à jour de message système et un message système mis à jour dans une période cible, le dispositif terminal étant dans l'état inactif RRC.
