1. A method performed by an access and mobility management function (AMF) for supporting an inter-system handover from an evolved packet system (EPS) system to a 5th generation (5G) system, the method comprising:
receiving, from a session management function (SMF), a first message including quality of service (QoS) flow information;
transmitting, to a base station, a handover request message including E-UTRAN radio access bearer (E-RAB) information and the QoS flow information;
receiving, from the base station, a handover request acknowledgement message including information indicating whether a data forwarding for at least one QoS flow associated with a protocol data unit (PDU) session is accepted or not, the information being determined based on the E-RAB information and the QoS flow information, when the PDU session is accepted by the base station; and
transmitting, to the SMF, a second message including tunnel information for the data forwarding,
wherein the E-RAB information includes an E-RAB identifier and data forwarding information.
