1. A method by a terminal in a wireless communication system, the method comprising:
receiving, by the terminal from a base station, a rust Radio Resource Control Reconfiguration (RRCReconfiguration), wherein the first RRCReconfiguration comprises configuration information related to state transition of the terminal, and wherein the configuration information related to state transition of the terminal comprises information on a timer;
transmitting, by the terminal to the base station, User Equipment Assistance Information (UEAssistanceInformation), wherein the UEAssistanceInformation comprises information related to state of the terminal;
starting, by the terminal, the timer after initiating transmission of the UEAssistanceInformation; and
transitioning, by the terminal and based on the timer being expired, to an IDLE state,
wherein the timer is configured to restart after completion of a first handover, wherein the first handover is associated with reception of an RRCReconfiguration that comprises a parameter for synchronous reconfiguration (reconfigurationWithSync),
wherein the timer is configured to not restart after completion of a second handover, wherein the second handover is associated with reception of a mobility from new radio command (MobilityFromNRCommand), and
wherein after an RRC reestablishment procedure and a cell selection, the timer is configured to stop based on a T311 timer being expired.
