DATA TRANSMISSION METHOD AND SYSTEM, AND APPARATUS
First Claim
1. A data transmission method, the method comprising:
- determining, by a link layer of a terminal, link state information of a wireless link established between the terminal and an access control point device;
sending the link state information from the link layer to a transport layer; and
sending, by the terminal to a server using the transport layer, a link notification corresponding to the link state information.

Abstract
This application provides a data transmission method and system, an apparatus, and belongs to the field of communications technologies. The method is applied to a terminal, a wireless link is established between the terminal and an access control point device, a transmission control protocol (TCP) connection is established between the terminal and a server, and the wireless link is used to bear the TCP connection. The method includes: determining, by the terminal, link state information of the wireless link by using a link layer, and sending the link state information from the link layer to a transport layer. The method also includes: sending, by the terminal to the server by using the transport layer, a link notification corresponding to the link state information. In this application, data transmission efficiency can be improved.
