Abstract

Les techniques décrites permettent à une station de base sans fil de recevoir des instructions d'urgence destinées à des UE aériens et provenant d'un système tiers. La station de base peut générer un message de diffusion contenant les instructions d'urgence, des paramètres associés et une indication précisant que le message de diffusion est destiné à des UE aériens. La station de base peut transmettre un message court indiquant à des UE aériens de surveiller le message de diffusion et peut transmettre le message de diffusion en conséquence. Un UE aérien peut recevoir le message court et le message de diffusion. Puis, sur la base de l'indication précisant que le message de diffusion est destiné à des UE aériens, l'UE aérien peut décoder les informations d'urgence du message de diffusion de façon à obtenir les instructions d'urgence et les paramètres associés. L'UE aérien peut entreprendre une ou plusieurs actions sur la base des instructions d'urgence décodées.
