Abstract

This application provides a data transmission method and communications devices. In some implementations, a first device instructs a second device to stop sending data of an application to the first device, receives from the second device first indication information indicating a sequence number of data that is of the application and that has been received by the second device from the first device, and sends to the second device second indication information indicating a sequence number of data that is of the application and that has been received by the first device from the second device. After a connection between the terminal device and a second server is established, the first and second indication information are used to transmit the data of the application through the connection.
