Claim 14:
15. A method performed by a radio terminal, the method comprising:
receiving a first Radio Resource Control (RRC) message related to reconfiguration of a RRC connection from a master Radio Access Network (RAN) node or a secondary RAN node; and
sending a second RRC message related to completion of the reconfiguration of the RRC connection, wherein
the radio terminal has a PDU session established between the radio terminal and a User Plane Function (UPF) in a core network, the core network being associated with the master RAN node and the secondary RAN node, and
the first RRC message includes a PDU Session ID and a QoS Flow Indicator (QFI),
wherein a QoS Flow which is indicated by the QFI and associated to the PDU session indicated by the PDU Session ID is moved to the secondary RAN node.
