1. A method performed by a master base station in a wireless communication system, the method comprising:
transmitting, to a secondary base station, a secondary base station addition request message including an identity of a data radio bearer (DRB) and a quality of service (QoS) requirement associated with the DRB;
receiving, from the secondary base station, a secondary base station addition response message including the identity of the DRB, transport layer information for an user plane on an Xn interface, a radio resource control (RRC) container, and an identity of a protocol data unit (PDU) session, wherein the RRC container includes configuration information of a secondary cell associated with the secondary base station;
transmitting, to a user equipment (UE), an RRC reconfiguration message including the RRC container;
receiving, from the UE, an RRC reconfiguration complete message as a response to the RRC reconfiguration message; and
transmitting, to the secondary base station, a secondary base station reconfiguration complete message.
