1. A method by a terminal in a wireless communication system, the method comprising:
receiving, from a source base station, a dedicated radio resource control (RRC) message including a handover (HO) command;
obtaining a system information block (SIB);
identifying whether a dual active protocol stack (DAPS) HO is configured;
identifying whether the obtained SIB is SIB1;
in case the obtained SIB is SIB1, identifying whether the SIB1 is obtained from the dedicated RRC message;
in case that the DAPS HO is configured and the SIB1 is obtained from the dedicated RRC message, identifying whether a preconfigured event occurs; and
in case that the DAPS HO is configured and the SIB1 is obtained from the dedicated RRC message, performing at least one operation according to the SIB1 after the preconfigured event occurs.
