The foundation of TCP connection is subjected to three-way handshake process:
First time handshake phase: it is syn=1 that terminal device, which sends position code, the data packet of seq is randomly generated to server,
Server-side is known that terminal device requires to establish online by syn=1.
The second handshake stage: server will confirm on-line information after receiving request, send ACK to terminal device
The data packet of seq is randomly generated in number=seq+1, syn=1, ACK=1.
Third time handshake phase: terminal device checks whether ACK number is correct after receiving, i.e., sends for the first time
Whether seqnumber+1 and position code ACK is 1, if correctly, terminal device can retransmit the seq of ACK number=server
+ 1, ACK=1, confirmation seq value is then connect with ACK=1 after server receives is successfully established, and completes above-mentioned three-way handshake, terminal
Equipment and server start to transmit data.
By three-way handshake above, a TCP connection can be successfully established.When TCP connection is successfully established, Ji Kejin
Between the corresponding TCP session of row namely terminal device and server data interaction can be carried out by the TCP connection.

Defeated time delay.The default transport time delay refers in the prior art, determined in TCP connection data packet that sender sends whether packet loss
Propagation delay time, such as when the default transport delay be RTT0, since sender sends data, if in RTT0It does not receive inside and
From the confirmation message of recipient, it is determined that the data packet that sender sends has been lost, and needs to retransmit data packet.
The judgment module 30 judges whether terminal device receives server according to the IP data in the first propagation delay time
The ACK confirmation message that message returns, when terminal device receives server according to IP datagram text in the first propagation delay time
When the ACK confirmation message of return, then it is assumed that IP datagram text is successfully sent to server by terminal device；When terminal device
When the ACK confirmation message that server is returned according to the IP datagram text is not received in one propagation delay time, then it is assumed that terminal device
IP datagram text server is not successfully sent to.

When message, third control module 40 retransmits IP datagram text to server by LTE network, due to LTE network than comparatively fast and
Stablize, which can receive the ACK confirmation message of server return in default transport time delay, so that the terminal device
The IP datagram text is thought there is no losing, i.e., the terminal device thinks that the terminal device will not there is no packet loss event occurs
Congestion control is carried out, which is still able to maintain preferably transmission rate (transmission rate originally).
As in one embodiment, which is RTT1, default transport delay is RTT0, the RTT1It is less than
RTT0, 20 controlling terminal equipment of the second control module is literary to server transmission IP datagram by WiFi network, then judges mould
Block 30 judges terminal device in the first propagation delay time RTT1Inside whether receive the ACK that server is returned according to the IP datagram text
Confirmation message, when terminal device in the first propagation delay time RTT1Do not receive what server was returned according to the IP datagram text
When ACK confirmation message, third control module 40 retransmits the IP datagram text to server by LTE network, common, the end
End equipment quickly can receive the ack msg message that server is returned according to the IP datagram text, such as terminal by LTE network
Equipment is RTT by the propagation delay time that LTE network sends IP datagram text2, the RTT1And RTT2And be less than RTT0, then end
End equipment thinks in default transport time delay RTT0ACK confirmation message is inside had received, so that the terminal device thinks the IP data
Message is there is no losing, i.e., the terminal device thinks that the terminal device not will do it congestion control there is no packet loss event occurs,
The terminal device is still able to maintain preferably transmission rate (transmission rate originally).Due to first propagation delay time RTT1Less than silent
Recognize propagation delay time RTT0, the terminal device is in the first propagation delay time RTT1When not receiving ACK confirmation message inside, by IP datagram
Text is sent to server by LTE network from being switched to by WiFi network, to receive ACK confirmation in default transport time delay
Message, so that terminal device thinks that there is no packet loss events.
Above-described embodiment is sampled, terminal device establishes TCP connection by WiFi network and server, and then terminal device is logical
It crosses WiFi network and sends IP datagram text to server；Terminal device judges whether receive server in the first propagation delay time
The ACK confirmation message returned according to the IP datagram text；First propagation delay time is less than the default transport time delay in TCP connection；
When terminal device does not receive the ACK confirmation message that server is returned according to the IP datagram text in the first propagation delay time,
Terminal device retransmits the IP datagram text to server by LTE network；I.e. terminal device is passing through WiFi network to service
When device sends IP datagram text, if not receiving the ACK that server is returned according to the IP datagram text in the first propagation delay time
When confirmation message, terminal device sends server by LTE network from being switched to by WiFi network for the IP datagram text,
To receive ACK confirmation message in default transport time delay, so that terminal device thinks that there is no packet losses；So that terminal device
It not will do it congestion control, to keep preferably transmission rate.
