Abstract

Les modes de réalisation de la présente invention concernent un procédé, un dispositif et un équipement de communication basés sur l'Internet des véhicules. Quand un dispositif utilisateur de véhicule a obtenu une instruction de configuration de paramètres envoyée par un serveur d'application de l'Internet des véhicules, le dispositif utilisateur peut analyser l'instruction de configuration de paramètres pour obtenir une identification de type de configuration dans l'instruction de configuration de paramètres et déterminer une politique de configuration de paramètres pour des paramètres de communication entre véhicules de voisinage proche, selon l'identification de type de configuration. En outre, les paramètres de communication entre véhicules de voisinage proche sont modifiés en fonction de la politique de configuration de paramètres et des paramètres de configuration transportés dans l'instruction de configuration de paramètres, et une communication entre véhicules de voisinage proche est réalisée selon les paramètres modifiés de communication de voisinage proche. Il se peut que même si le dispositif d'utilisateur de véhicule a été configuré avec des paramètres de communication entre véhicules de voisinage proche à partir du VCF, le serveur d'application de l'Internet des véhicules (VAS) peut également amener le dispositif d'utilisateur de véhicule à modifier les paramètres de communication entre véhicules de voisinage le plus proche selon les instructions de configuration de paramètres, par envoi d'une instruction de configuration de paramètres au dispositif d'utilisateur de véhicule, de façon à atteindre l'objectif de configuration des paramètres de communication entre véhicules de voisinage le plus proche par le dispositif d'utilisateur de véhicule à partir du VAS.
