ket filter set for uplink and optionally for downlink and a precedence value. Furthermore, for a dynamically assigned QFI, the QoS rule contains the QoS parameters relevant to the UE (e.g., 5QI, GBR and MBR, and the averaging window7. There are more than one QoS rule associated with the same QoS flow. A default QoS rule is required for each PDU session and associated with the QoS flow of the default QoS rule. The default QoS rule is the only QoS rule of a PDU session that may contain no packet filter set in which case, the highest precedence value is used. If the default QoS rule does not contain a packet filter set, the default QoS rule defines the treatment of packets that do not match any other QoS rules in a PDU session. If the default QoS rule does not contain a packet filter, the reflective QoS is not applied to the QoS flow of the default QoS rule. The SMF performs binding of SDFs to QoS flows based on the QoS and service require- ments. The SMF assigns the QFI for a new QoS flow and derives its QoS profile from the information provided by the PCF. The SMF provides the QFI along with the QoS profile and a transport-level packet marking value for uplink traffic to the AN. The SMF further provides the SDF template, that is, the packet filter set associated with the SDF received from the PCF together with the SDF precedence value, the QoS-related information, and the corresponding packet marking information, that is, the QFI, the transport level packet mark- ing value for downlink traffic and optionally the reflective QoS indication to the UPF enabling classification, bandwidth enforcement and marking of user-plane traffic. For each SDF, when applicable, the SMF generates a QoS rule. Each of these QoS rules contain the QoS rule identifier, the QFI of the QoS flow, the packet filter set of the uplink part of the SDF template, and optionally the packet filter set for the downlink part of the SDF tem- plate, as well as the QoS rule priority value set to the SDF precedence value. The QoS rules are then provided t
