Claim 19:
20. A method performed by a central-unit-user plane (CU-UP) of a network node for exchanging information with a central-unit control plane (CU-CP) of the network node to manage Quality of Service (QoS) flows for the optimization of radio resources, the method comprising:
receiving, from the CU-CP of the network node, a request for the flow information for the 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 at least one QoS flow;
detecting an event triggering a reporting of flow information for the at least one QoS flow; and
transmitting, 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.
