Abstract
A data transmission method, wherein when small data arrives, user equipment (UE) in a radio resource control inactive state RRC_INACTIVE can establish a communication with a base station without entering an RRC connected state, so as to perform small data transmission (SDT). An RNAU timer for controlling a periodic radio access network (RAN) based notification area update is set for the base station. For the SDT, an SDT timer for SDT small data transmission is set. A small data transmission data radio bearer (DRB) is configured for the user equipment. When an RRC resume procedure is triggered by arrival of data at the DRB, a high layer triggering small data transmission, or the like, the user equipment starts the SDT timer.
