|Applicants:||HUAWEI TECHNOLOGIES CO., LTD.
|Title:||DATA TRANSMISSION METHOD, NETWORK DEVICE AND TERMINAL DEVICE|
A data transmission method, a network device and a terminal device. The method comprises: a network device determining activation indication information, wherein the activation indication information is used for indicating the starting or stopping of a transfer control protocol (TCP) quick confirmation function; the network device sending the activation indication information, and where the activation indication information indicates the starting of the TCP quick confirmation function, maintaining a mapping relationship between a TCP sequence number and a radio link control layer protocol data unit (RLC PDU) sequence number; and the terminal device receiving the activation indication information, and starting or stopping the TCP quick confirmation function according to the activation indication information. Therefore, the method for performing data transmission by means of a TCP quick confirmation solution can be optimized.
