Claim 0:
1. A method performed by a central-unit-control plane (CU-CP) of a network node for exchanging information with a central-unit user plane (CU-UP) of the network node to manage Quality of Service (QoS) flows for the optimization of radio resources, the method comprising:
transmitting, to the CU-UP, a request for flow information for at least one QoS flow, wherein transmitting the request for the flow information for the at least one QoS flow comprises:
inserting an information element in the QoS-Flow descriptor in a E1 Bearer Context Setup Request message or an E1 Bearer Context Modification Request message, the information element indicating to the CU-UP to report uplink or downlink traffic for the at least one QoS flow;

receiving, from the CU-UP of the network node, the flow information for the at least one QoS flow, wherein the flow information indicates that data traffic is detected for the at least one QoS flow; and
based on the flow information for the at least one QoS flow, taking at least one action.
