Abstract

La présente invention concerne un procédé permettant d'envoyer des données dans l'Internet des véhicules, un terminal et un dispositif de réseau. Selon un aspect, dans un mode de réalisation de la présente invention, lorsqu'un terminal sélectionne une porteuse, le terminal obtient un paramètre de condition de congestion d'un groupe de ressources utilisé par chacune d'au moins une porteuse du terminal ; et si le paramètre de condition de congestion du groupe de ressources utilisé par chaque porteuse est supérieur à un seuil de congestion configuré par la porteuse, le terminal peut sélectionner une porteuse en retardant un temps spécifié, de façon à envoyer des données dans un système d'Internet des véhicules.
