Les modes de réalisation de la présente divulgation divulguent un procédé et un appareil de mise à jour de politique d'équipement terminal, qui peuvent être appliqués à un système de 5e génération (5GS). Le procédé comprend les étapes suivantes : une fonction de commande de politique (PCF) acquiert des informations d'opération auxiliaire d'état de terminal d'un équipement terminal à partir d'une fonction d'application (AF) ; et la PCF génère ou met à jour, sur la base des informations d'opération auxiliaire d'état de terminal, une politique de l'équipement terminal par rapport à une session de service ou à un flux de données de service. Au moyen de la mise en œuvre des modes de réalisation de la présente divulgation, des informations d'opération auxiliaire d'état de terminal peuvent être utilisées pour déclencher une mise à jour de politique d'un équipement terminal, de façon à fournir une qualité et une politique de service correspondantes pour l'équipement terminal, ce qui permet d'obtenir un équilibre entre des facteurs tels que le débit, le retard et la fiabilité.
