Abstract

La divulgation concerne un système de communication 5G ou 6G destiné à prendre en charge un débit supérieur de transmission de données. Un procédé mis en œuvre par un producteur de service de gestion (MnS) dans un système de réseau non terrestre (NTN) consiste à : recevoir, en provenance d'un consommateur de MnS, une demande de création d'instance d'objet gérée (MOI) pour une classe d'objets d'informations (IOC) pour des informations de satellite, l'IOC pour des informations de satellite comprenant des informations relatives à un éphéméride et un mode de fonctionnement de stockage et de transfert (S&F) ; configurer, sur la base de l'IOC pour des informations de satellite, un MOI pour des informations de satellite pour une station de base ; et transmettre, au consommateur de MnS, une réponse indiquant une configuration réussie du MOI pour des informations de satellite.
