Abstract
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a terminal in a wireless communication system is provided. The method may include: receiving, from a base station, a radio resource control (RRC) release message including a parameter indicating a timer that triggers a radio access network based notification area (RNA) update; transitioning to an RRC inactive state and starting the timer, based on the RRC release message; in case that criteria for small data transmission (SDT) are met while the timer is running, transmitting, to the base station, an RRC resume request message for the SDT, wherein the timer is not stopped when the RRC resume request message is transmitted; and in case that the timer expires while the SDT is ongoing, setting a variable indicating whether the RNA update is pending, to a true value.
