Abstract

La présente divulgation concerne un procédé, un dispositif et un système de rapport de mesure de qualité d'expérience, et un support de stockage. Le procédé de rapport de mesure de qualité d'expérience comprend : lorsqu'un côté réseau d'accès sans fil est surchargé, la réalisation, par une station de base, selon des paramètres pertinents, d'une opération correspondante sur un rapport de mesure de qualité d'expérience. L'opération correspondante consiste en ce que : selon les paramètres pertinents, la station de base donne l'ordre à un terminal d'utilisateur de stocker le rapport de mesure de qualité d'expérience dans la couche d'application, et/ou de stocker ledit rapport dans la couche d'accès, et/ou de stocker ledit rapport simultanément dans la couche d'application et dans la couche d'accès, et/ou de rejeter directement ledit rapport, et/ou de stocker ledit rapport dans la couche d'application et/ou dans la couche d'accès et de rejeter ledit rapport après qu'une condition prédéterminée est satisfaite. La présente divulgation décrit un mécanisme de traitement de rapport de mesure de qualité d'expérience approprié pour un système 5G NR lorsque le côté RAN est surchargé, ce qui permet de protéger des données critiques de mesure de qualité d'expérience tout en réduisant la charge sur le côté RAN.
