Abstract
This application provides a data transmission method, apparatus and system, so as to copy data in a system memory to a sending queue of a first communications module through a system bus, and then send the data to a second terminal based on the first communications module. Device to device communication, directly through system memory copying and MAC/PHY layer 2 forwarding, greatly optimizes load and delay of Wi-Fi packet forwarding, which can effectively reduce time spent on data transmission of device to device services, effectively reduce system load, reduce transmission delay, and increase the Wi-Fi throughput.

1-13. (canceled)
A data transmission system includes a first terminal and a second terminal, wherein the first terminal includes a first communication module, characterized in that it includes:
- establishing point-to-point communication between the first terminal and the second terminal;
- obtaining, by the first terminal, an application data frame;
- generating, by the first communication module of the first terminal, a message, the message is a message generated by the first communication module adding a wireless network field to the application data frame based on the 802.11 MAC/PHY layer control protocol, wherein, the first communication module is a WIFI chip;
- sending the message to the second terminal through the first communication module by the first terminal;
- receiving, by the second terminal, the message;
- parsing the received message to obtain the application data frame by the second terminal.
A data transmission method, applied to a first terminal, is characterized in that, comprising:
- establishing point-to-point communication with the second terminal;
- obtaining the application data frame;
- generating a message, where the message is a message generated by the first terminal adding a wireless network field to the application data frame based on the 802.11 MAC/PHY layer control protocol;
- sending the message to the second terminal.
A terminal device, characterized in that it comprises:
- a memory and a processor, wherein the memory is used to store a computer program;
- the processor is configured to perform the following steps:
- establishing point-to-point communication with the second terminal;
- obtaining the application data frame;
- generating a message, where the message is a message generated by the first terminal adding a wireless network field to the application data frame based on the 802.11 MAC/PHY layer control protocol;
- sending the message to the second terminal.
