Abstract

Des modes de réalisation de la présente divulgation concernent une solution pour la création d'un rapport de qualité d'expérience (QoE) de réseau non terrestre (NTN) avec des informations de transfert. En particulier, un dispositif terminal groupe des informations de transfert à des données de création de rapport de mesure de QoE et envoie les informations à un réseau. De cette manière, de telles informations aident le réseau à identifier la cause d'une variation de l'expérience utilisateur. En outre, elles permettent également d'optimiser des performances d'un système NTN.
