Abstract: The present application provides a data transmission method, a device, and a storage medium. An anchor base station initiates radio paging to a terminal, and initiates RAN paging to a non-anchor base station in an RNA after receiving a downlink small data packet from a core network that is sent to the terminal in an RRC Inactive state; a radio paging message and an RAN paging message include indication information on downlink small data transmission (SDT); and after receiving the radio paging message, the terminal resumes SDT-related configuration in the RRC Inactive state, and the anchor base station sends the downlink small data packet to the terminal directly or through the non-anchor base station.
