Abstract: An application processor sends a TCP packet to the modem, where the TCP packet is used by the modem to generate a wireless protocol data packet corresponding to the TCP packet, so that the modem sends the wireless protocol data packet to a base station. The application processor receives first status information from the modem, where the first status information is status information of the wireless protocol data packet or status information of the TCP packet.

If the TCP packet is successfully sent to the base station, the application processor starts a retransmission timer corresponding to the TCP packet. If the TCP packet is not successfully sent to the base station, the application processor sends the TCP packet to the modem again.
