Abstract
In one illustrative example, a user plane function (UPF) may detect initial traffic for an application for a user equipment (UE) for which no current dedicated Quality of Service (QoS) flow is established. In response, the UPF may send, to a control plane function, a message which indicates a request for creating a dedicated QoS Flow for traffic for the application for the UE. The message may include flow metadata and an application identifier obtained in detecting the initial traffic. A QoS Flow may then be created for the traffic based on a selected QoS policy associated with the application identifier. Subsequently, the UPF may determine that a measured time period of traffic inactivity for the QoS Flow is outside a limit set by a threshold. Based on the determining, the UPF may send, to the control plane function, a message which indicates a request for deleting the QoS Flow.
