Abstract

La présente invention concerne un procédé de configuration de règle de filtrage et de transmission de données, et un appareil associé, utilisé pour résoudre au moins l'un des problèmes dans l'état de la technique de la latence élevée de transmission de données de liaison montante et de l'absence d'une solution de transmission pour des données de liaison descendante. Dans les modes de réalisation de la présente invention, le guidage de flux de données est préconfiguré sur la base des exigences d'application, et une règle de filtrage de trafic est préconfigurée pour un élément de réseau associé, de sorte que la transmission de données peut être mise en œuvre pour des données de liaison montante et des données de liaison descendante sur la base de la règle de filtrage de trafic configurée. Ainsi, le guidage et la conversion de données peuvent être mis en œuvre au moyen de la règle de filtrage de trafic configurée sans qu'il soit nécessaire que l'IP externe de l'UE de surveillance soit surveillé et rapporté par une UPF, réduisant la latence de la transmission de données de liaison montante et mettant également en œuvre la transmission de données de liaison descendante.
