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).

Abstract: Transport information of a second communication system is allocated to at least one radio access bearer between a terminal device and a first packet core serving device of a first communication system. Information about the at least one allocated tunnel endpoint is signalled to a network access device of the first communication system, and data received from the first packet core serving device of the first communication system at one of the at least one allocated tunnel endpoints and data received from a second packet core serving device of the second communication system is forwarded to the terminal device during an inter-system handover.
