Abstract

The invention provides a data transmission method, device and system, and the method comprises the steps: copying data in a system memory into a transmission queue of a first communication module through a system bus, and transmitting the data to a second terminal based on the first communication module. Communication between devices is directly carried out through system memory copying and MAC / PHY two-layer forwarding, the load and time delay of WiFi message forwarding are greatly optimized, the time consumed by data transmission of point-to-point services can be effectively shortened, the system load is effectively reduced, the transmission time delay is reduced, and the throughput rate of WiFi is improved.

Description

technical field [0001] The present application relates to the field of communications, and in particular, to a data transmission method, device, and system. Background technique [0002] The point-to-point (Device to Device, D2D) communication technology refers to a communication method that directly communicates between two peer user nodes (devices). WiFi Direct is a communication mode that can realize point-to-point services. High-speed data communication between devices, the data transmission is based on the TCP / IP protocol, which has the advantages of fast data transmission speed and long transmission distance. figure 1 A schematic diagram of the existing process of data transmission based on the TCP / IP protocol is shown, such as figure 1 As shown in the figure, when the sender sends a message, the application software encapsulates the data packet to be sent according to the TCP / IP protocol specification. Implement forwarding. After receiving the data, the receiver al...
