Abstract

L'invention concerne un procédé de transmission de données et un équipement utilisateur (UE) visant à résoudre le problème de l'état de la technique qui, lorsqu'un équipement utilisateur (UE) utilise un nom de point d'accès (APN) d'un réseau 3G ou un APN erroné pour activer une connexion PDN utilisée pour transmettre un service de données, ne permettait pas d'établir une connexion PDN. Le procédé consiste à : après s'être enregistré sur un réseau LTE, un équipement utilisateur (UE) détermine que l'établissement d'une première liaison PDN avec le réseau LTE de transmission de service de données a échoué; l'UE utilise une seconde connexion PDN établie dans le processus d'enregistrement pour transmettre un service de données entre l'UE et le réseau LTE, l'APN correspondant à la seconde connexion PDN prenant en charge le type de service de données à transmettre. Du fait que l'APN correspondant à la seconde connexion PDN prend en charge le type de service de données à transmettre, l'UE peut transmettre le service de données au réseau LTE en utilisant la seconde connexion PDN, répondant ainsi aux besoins de l'utilisateur visant à utiliser le service de données dans le réseau LTE, et améliorant l'expérience de l'utilisateur.
