Method and apparatus for performing, by terminal in wlan interworking operation, handover

A terminal for performing a handover procedure during a WLAN interworking operation in a wireless communication system, the terminal comprising:

• memory;
• a transceiver;
• and
• a processor connecting the memory and the transceiver, wherein the processor is configured to perform control so that the terminal receives a handover command which commands the terminal to perform handover from a source cell to a target cell and comprises a WLAN interworking configuration indication to indicate that the terminal maintains or releases a WLAN interworking configuration for a WLAN being accessed by the terminal and that the terminal attempts to perform the handover to the target cell in a state in which the terminal has maintained the WLAN interworking configuration if the WLAN interworking configuration indication indicates that the terminal maintains the WLAN interworking configuration.
