Abstract

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. According to an embodiment, the method comprises initiating a small data transmission (SDT) procedure, in a radio resource control (RRC) inactive state, obtaining a report for a log connection failure or an SDT procedure failure, based on an expiry of an SDT timer, wherein the report for the log connection failure includes information indicating that the report is for SDT and in case that the UE enters an RRC connected state, and transmitting the report to a base station, based on a request for the report from the base station.
