Fuente: Wipo "IOT" The present application relates to the technical field of communications, and provides a data transmission method and a related apparatus. The method comprises: an A-IoT device sends first information to a network device, the first information comprising state information of the A-IoT device and/or indication information, and the indication information being used for indicating whether the first information comprises the state information of the A-IoT device; and the network device parses the first information to identify whether the first information comprises the state information of the A-IoT device. The network device is prevented from incorrectly decoding an A-IoT data packet, thereby improving the accuracy of A-IoT data transmission. Furthermore, when obtaining the state information of the A-IoT device, the network device can decide a communication process on the basis of the state information of the A-IoT device, thereby improving the communication performance and efficiency between the network device and the A-IoT device.
