Abstract
(EN) A method in a User Plane Function (UPF) comprising receiving from a Policy Control Function (PCF), an instruction to create a new Packet Detection Rule (PDR), the instruction comprising an IP address for the wireless device, a value of a ToS field, and a quality-of-service, QoS, reference or charging policy. The method further comprises storing the IP address, the value of the ToS field, and the QoS reference or charging policy as a predetermined PDR. The method further comprises subsequently receiving, from a wireless device, a first packet targeted to an application server, AS, mapping the first packet to the predetermined PDR, based on a value of a ToS, field in the first packet, and adding a 5-tuple associated with the first packet to the predetermined PDR. This serves to bind the new connection to the PDR.
(FR) L'invention concerne un procédé d'une fonction de plan utilisateur (UPF) consistant à recevoir, d'une fonction de commande de politique (PCF), une instruction ayant pour objet de créer une nouvelle règle de détection de paquet (PDR), l'instruction comprenant une adresse IP associée au dispositif sans fil, une valeur d'un champ de ToS, et une politique de référence de qualité de service, QoS, ou de facturation. Le procédé consiste en outre à mémoriser l'adresse IP, la valeur du champ de ToS, et la politique de référence de QoS ou de facturation en tant que PDR prédéfinie. Le procédé consiste en outre à recevoir ultérieurement, d'un dispositif sans fil, un premier paquet ciblé pour un serveur d'application, AS, à mapper le premier paquet sur la PDR prédéfinie, sur la base d'une valeur d'un champ de ToS du premier paquet, et à ajouter un 5-tuple associé au premier paquet à la PDR prédéfinie. Ceci sert à lier la nouvelle connexion à la PDR.
