1. A method performed by a secondary node (SN), the method comprising:
determining that a number of radio terminals to be served with user plane data (UPD) associated with at least one Quality of Service (QOS) flow exceeds a threshold;
transmitting, in response to the determining, a request indicating a de-mapping of the at least one QoS flow from a unicast radio channel (UCH) between the SN and a radio terminal (UE), and indicating a mapping of the at least one QoS flow to a multicast radio channel (MCH) between the SN and a plurality of radio terminals, the plurality of radio terminals comprising the UE;
de-mapping the UPD associated with the at least one QoS flow from the UCH; and
mapping UPD associated with the at least one QoS flow to the MCH.
