Abstract

La présente invention concerne un procédé et un dispositif de rapport d'informations. Le procédé comprend les étapes suivantes : lorsqu'un équipement utilisateur (UE) envoie, à une station de base, une confirmation que l'établissement d'une connexion RRC est terminé, qu'un rétablissement de connexion RRC est terminé ou qu'une récupération de connexion RRC est terminée, l'UE rapporte, à la station de base, des informations de capacité et/ou des informations d'indication de préférence pour indiquer un mode de transmission de données concernant l'UE. La présente invention résout le problème dans l'état de la technique pertinent selon lequel un eNode B ne peut pas acquérir la capacité de l'UE du fait que la capacité de prise en charge de schéma d'optimisation de transmission de l'UE et une indication de préférence sont mémorisées dans une MME et ne sont pas visibles par l'eNode B.
