Abstract

Un mode de réalisation de la présente invention concerne un procédé de transmission de données, un dispositif, un équipement utilisateur et une puce de modulateur-démodulateur, le procédé de transmission de données permettant de prendre en charge un équipement utilisateur ou LTE assorti d'une communication de données mobile 5G. Le procédé consiste : à recevoir, par l'équipement utilisateur, un message de radiomessagerie transmis par un dispositif côté réseau; et dans un cas où le message de radiomessagerie est utilisé pour identifier un service de données, et où les données mobiles de l'équipement utilisateur sont arrêtées, à ignorer le message de radiomessagerie. Si les données mobiles de l'équipement utilisateur sont arrêtées, l'équipement utilisateur ne peut pas exécuter de service de données. L'équipement utilisateur ignore directement le message de radiomessagerie de sorte que l'équipement utilisateur n'engage plus une série d'actions suivies telles qu'une connexion RRC, ce qui permet d'économiser une consommation d'énergie de l'équipement utilisateur.
