1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a first base station operating based on a first radio access technology (RAT), a user equipment (UE) information request including information indicating whether the terminal reports a radio link failure (RLF); and
in case that the information indicates a reporting of the terminal for the RLF. transmitting, to the first base station, a UE information response including a.n RLF report including logging information for a cell of a second base station that operates based on a second RAT,
wherein the logging information includes cell related information including a public land mobile network (PLMN) identity,
wherein the PLMN identity is identified based on a first PLMN entry of a PLMN identity list included in system information, the system information being transmitted from the second base station to the terminal, and
wherein the PLMN identity list corresponds to a core network of the second RAT to which the cell is connected, the cell being where the RLF is detected or being a source cell of a failed handover.
