Abstract

La présente invention concerne un procédé et un dispositif de configuration de ressource d'intervalle de temps TDD (duplexage par répartition dans le temps), une station de base, une entité de gestion de mobilité (MME), et un support de stockage lisible par ordinateur. Le procédé de configuration de ressource d'intervalle de temps TDD consiste à : ajouter un nouvel élément d'information (IE) à une première signalisation de demande de transfert si l'exécution d'un transfert vers une station de base cible via une interface S1 est déterminée d'après un rapport de mesure rapporté par un véhicule aérien sans pilote, la première signalisation de demande de transfert étant utilisée par une station de base source pour transporter le nouvel IE ; et envoyer le nouvel IE à la station de base cible au moyen d'une MME, de sorte que la station de base cible configure une ressource d'intervalle de temps TDD pour le véhicule aérien sans pilote d'après le nouvel IE. Les modes de réalisation de la présente invention peuvent permettre au véhicule aérien sans pilote d'obtenir rapidement, sous la station de base cible, une ressource d'intervalle de temps TDD satisfaisant son volume de trafic après un transfert basé sur une interface S1.
