1. A method performed by a master base station supporting a dual connectivity with a secondary base station in a wireless communication system, the method comprising:
transmitting, to the secondary base station, address information associated with data forwarding;
receiving, from the secondary base station, a first message associated with a data usage of the secondary base station, the first message including information on a data volume for a radio access technology (RAT) of the secondary base station; and
transmitting, to a first network entity performing a mobility management, a second message including the information on the data volume for the RAT of the secondary base station, based on a trigger by a handover of a terminal from the master base station that is a source base station to a target master base station,
wherein the data volume for the RAT of the secondary base station reported to the first network entity excludes data that is forwarded from the secondary base station to the target master base station based on the address information during the handover.
