Abstract
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 flow identifier associated with the first packet to the predetermined PDR. This serves to bind the new connection to the PDR.
