Abstract

Disclosed are a method and device for processing data transmission by a machine-type communication device. The method comprises: determining, by the network side, the mode for the machine-type communication device to transmit a small amount of user data using a control plane; instructing, by the network side, the machine-type communication device to transmit the small amount of user data using the control plane according to the determined mode; and transmitting, by the machine-type communication device, the small amount of user data using the control plane, according to instructions from the network side. In the present application, on the one hand, the mode of transmitting user data by a control plane can be used in transmitting a small amount of data, so as to improve the system efficiency; and on the other hand, the possibility of causing or increasing the congestion in signalling transmission and/or processing can be avoided when making full use of the mode of transmitting user data by the control plane in transmitting the small amount of data, thus improving the performance of a long-term evolution system in supporting the machine-type communication device.
