Claim 20:
21. A network node for managing Quality of Service (QoS) flows for the optimization of radio resources, the network node comprising:
processing circuitry operating as a central-unit-user plane (CU-UP) of the network node, the processing circuitry configured to:
receive, from a central-unit-control plane (CU-CP) of the network node, a request for the flow information for at least one QoS flow, wherein the request comprises a E1 Bearer Context Setup Request message or an E1 Bearer Context Modification Request message, and wherein an information element in a QoS-Flow descriptor in the request indicates to the CU-UP to report uplink or downlink traffic for the at least one QoS flow;
detect an event triggering a reporting of flow information for the at least one QoS flow; and
transmit, to the CU-CP of the network node, flow information associated with the at least one QoS flow, wherein the flow information indicates that data traffic is detected for the at least one QoS flow.
