9. A method of a target radio access network (RAN) node connected to a Fifth Generation Core (5G Core) network, the method comprising:
receiving, a source RAN node, a Handover Request message on an interface between the target RAN node and the source RAN node connected to the 5G Core network; and
transmitting, to the source RAN node, a Handover Request Acknowledge message including a transparent container that contains radio resource configuration information which is transferred to a radio terminal via the source RAN node,
wherein the Handover Request message includes: slice information, list information of a Protocol Data Unit (PDU) Session, and flow list information indicating at least one flow to be setup,
wherein the slice information identifies a network slice, the network slice being a logical network,
wherein the list information of the PDU Session includes a PDU Session ID corresponding to a PDU Session,
wherein the at least one flow indicated in the flow list information is configured within the PDU session, and
wherein the flow list information includes:
a flow identifier identifying the at least one flow within the PDU session; and
a flow QoS parameter corresponding to the flow identified by the flow identifier.
