Abstract

La présente invention porte sur un procédé et un appareil d'attribution de ressources. Le procédé comprend les étapes suivantes : un dispositif de commande de réseau acquiert des informations d'indication de localisation rapportées par un terminal de véhicule ; le dispositif de commande de réseau attribue des ressources radio au terminal de véhicule en fonction des informations d'indication de localisation. Au moyen de la solution technique, un dispositif de commande de réseau peut attribuer des ressources radio d'un terminal de véhicule selon les informations d'indication de localisation rapportées par le terminal, ce qui permet de résoudre le problème de l'état de la technique selon lequel des interférences mutuelles existent entre terminaux lorsque les terminaux sont trop proches les uns des autres et envoient des messages à l'aide d'une même ressource de fréquence temporelle, et ce qui permet d'éviter les interférences causées par l'utilisation d'une même ressource radio par des terminaux de véhicule qui sont trop proches les uns des autres, c'est-à-dire que le taux d'utilisation des ressources radio est amélioré sans interférence ni manquement.
