Abstract: There is provided a method comprising transmitting (102) a request (MR#1) indicating a de-mapping of at least one QoS flow from a unicast radio channel (UCH) between a secondary node (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 secondary node (SN) and a plurality of radio terminals, the plurality of radio terminals comprising the radio terminal (UE); and demapping (108) received user plane data (upd) associated with the at least one QoS flow from the unicast radio channel (UCH); and mapping (110) the received user plane data (upd) associated with the at least one QoS flow to the multicast radio channel (MCH).
