Title: DATA TRANSMISSION METHOD, DEVICE AND SYSTEM
Abstract:
The present invention relates to the technical field of radio communications. Disclosed are a data transmission method, device and system, for use in resolving the problem in an existing connectionless data transmission mechanism of increase in resource overhead due to that all base stations need to send paging messages carrying downlink data to the UE. The data transmission method comprises: a first MTC GW receives first uplink data that carries a UE identifier and is sent by a first base station; determining, according to the UE identifier in the first uplink data, that the UE is located in the coverage of the first base station; and triggering, by sending downlink data of the UE to the first base station, the first base station to send a first paging message to the UE, wherein the first paging message comprises downlink data of the UE.
