Abstract

La présente divulgation se rapporte au domaine technique des communications et concerne en particulier des procédés et des appareils de réception d'informations, des procédés et des appareils d'envoi d'informations, un terminal, un dispositif de réseau et un support de stockage. Un procédé de réception d'informations consiste à : recevoir des premières informations envoyées par un dispositif de réseau aérien, les premières informations étant utilisées pour indiquer des informations relatives au stockage et au transfert du dispositif de réseau aérien. Sur la base de la présente divulgation, le dispositif de réseau aérien peut indiquer à un premier terminal les informations relatives au stockage et au transfert du dispositif de réseau aérien au moyen des premières informations, de sorte que le premier terminal peut connaître les informations relatives au stockage et au transfert du dispositif de réseau aérien d'une manière relativement complète, et le premier terminal peut choisir en conséquence d'exécuter des opérations appropriées, ce qui permet d'éviter les problèmes techniques provoqués par l'abandon des informations de liaison montante par le dispositif de réseau aérien, l'impossibilité des opérations de stockage et de transfert du dispositif de réseau aérien de satisfaire aux exigences de service des informations de liaison montante, etc. après que le premier terminal envoie les informations de liaison montante au dispositif de réseau aérien.
