Abstract

Selon certains modes de réalisation, la présente invention concerne un procédé et un dispositif de traitement de données d'utilisateur ainsi qu'un système de réseau. Le procédé consiste à : déterminer, au moyen d'une SNC, conformément à des informations de plan de commande obtenues, des informations de chemin de traitement d'un chemin de données pour traiter des données d'utilisateur d'un UE et des informations de politique de traitement de nœuds situés sur le chemin de données, les informations de chemin de traitement comprenant des informations des nœuds situés sur le chemin de données et des informations de politique d'acheminement des nœuds situés sur le chemin de données, et les informations de politique de traitement comprenant des procédés de traitement et des paramètres de traitement permettant de traiter les données d'utilisateur par les nœuds situés sur le chemin de données ; et envoyer, au moyen de la SNC, les informations de chemin de traitement et les informations de politique de traitement à un point d'entrée et envoyer les informations de politique de traitement à un nœud de fonction situé sur le chemin de données, de sorte que le point d'entrée marque les données d'utilisateur conformément aux informations de chemin de traitement et aux informations de politique de traitement après avoir reçu les données d'utilisateur, et que le nœud de fonction situé sur le chemin de données traite les données d'utilisateur marquées par le point d'entrée après avoir reçu les données d'utilisateur marquées par le point d'entrée conformément aux informations de politique de traitement reçues.
