Abstract: Provided are a method, a device and a system for transmitting data through control plane signaling. The method comprises: a user equipment determining whether the data volume of currently-to-be-transmitted data exceeds a threshold; if the data volume of the currently-to-be-transmitted data exceeds the threshold, the user equipment sending the currently-to-be-transmitted data to an access network device in multiple transmissions by bearing each part of the currently-to-be-transmitted data in a non-access stadium protocol data unit (NAS PDU) in radio resource control (RRC) signaling in each transmission, wherein the RRC signaling carrying data transmission control information and the data transmission control information being used to instruct the access network device to buffer currently-received data. Through the disclosure, data whose data volume exceeds the threshold is sent to the access network device through control plane messages in multiple times, so as to reduce signaling overhead caused by data transmission, solve the problem that the method for sending data through control plane signaling in the related art cannot complete sending with a large data volume, optimize network performance, and improve system efficiency.
