1. A method performed by a master node (MN) in a wireless communication system, the method comprising:
receiving, from a source-secondary node (S-SN), a first message including an indication associated with a conditional primary secondary cell (PSCell) change, a list of PSCell candidates, and execution conditions;
transmitting, to a target-secondary node (T-SN), a second message including the indication associated with the conditional PSCell change and information on a candidate cell;
receiving, from the T-SN, a third message including information on at least one cell prepared and configuration information on the at least one cell prepared;
transmitting, to a terminal, a fourth message including the configuration information on the at least one cell prepared and at least one execution condition for the at least one cell prepared;
receiving, from the terminal, a fifth message as a response to the fourth message; and
transmitting, to the S-SN, a sixth message indicating a preparation of the conditional PSCell change.
