1. A method of a target radio access network (RAN) node, the method comprising:
receiving a Handover Request message from a core network during a handover of a radio terminal from a source RAN node to the target RAN node, the Handover Request message including information related to at least one Protocol Data Unit (PDU) session, the information including a flow indicator, a flow QoS parameter and priority indicator, the priority indicator indicating a relative importance of a flow compared to other flows; and
transmitting to the core network, in response to the Handover Request message, a Handover Request Acknowledge message including a Target to Source Transparent Container, the Target to Source Transparent Container including radio resource configuration information,
wherein the PDU session includes at least one flow, and
wherein a QoS is handled on a per-flow basis.
