Abstract

La présente demande divulgue un procédé de transmission de rapport de mesure, un dispositif terminal et un dispositif de réseau d'accès. Lorsque des rapports de mesure de couches d'application sont obtenus, le dispositif terminal peut se référer à des informations temporelles pour décider s'il faut encapsuler un rapport de mesure de couche d'application obtenu dans un premier message ou encapsuler une pluralité de rapports de mesure de couches d'application obtenus ensemble dans le premier message. Le dispositif terminal décide, sur la base des informations temporelles, de l'occasion pour encapsuler un ou plusieurs rapports de mesure de couches d'application et, par conséquent, la flexibilité du dispositif terminal rapportant les rapports de mesure de couches d'application à un dispositif de réseau d'accès est améliorée. De plus, lorsque le dispositif terminal détermine d'encapsuler une pluralité de rapports de mesure de couches d'application dans le premier message et envoie le premier message au dispositif de réseau d'accès, la signalisation servant à transmettre les rapports de mesure de couches d'application entre le dispositif terminal et le dispositif de réseau d'accès peut être réduite et le taux d'utilisation de la signalisation servant à transmettre les rapports de mesure de couches d'application peut être amélioré.
