Abstract

L'invention concerne un procédé et dispositif de gestion de service de données. Le procédé comprend les étapes suivantes : un premier dispositif de réseau reçoit un premier message transportant une première indication envoyée par un second dispositif de réseau, la première indication est utilisée afin d'indiquer qu'un terminal possède des données fermées ; et le premier dispositif de réseau paramétrant un modèle de flux de transport (TFT) d'une porteuse du terminal, de sorte que des données d'un premier service soient transmises par l'intermédiaire de la porteuse, et des données d'un second service ne peuvent pas être transmises par l'intermédiaire de la porteuse. Ainsi, un service peut être commandé de façon flexible, le rétablissement d'une connexion PDN peut également être évité après qu'un terminal ouvre des données, et la signalisation de surdébits est réduite, ce qui permet d'améliorer l'efficacité de gestion.
