[0097] Based on the first embodiment of the terminal device above, the terminal device further includes:

[0098] The receiving module 50 is configured to receive the response data returned by the server to the terminal device according to the second IP address.

[0099] The receiving module 50 receives the response data returned by the server according to the second IP address. After the server receives the IP data message resent by the terminal device through the LTE network, it returns the response data to the terminal device according to the original route, such as the terminal device passes through the LTE network. Send an IP data message to the server, and the server also returns response data to the terminal device through the LTE network, that is, when the server returns response data to the terminal device, the destination IP address is the second IP address, and the terminal device receives the response data returned by the server through the LTE network. response da...

Abstract

This invention discloses a terminal device. The terminal device comprises a first control module, a second control module, a judge module and a third control module; the first control module is used for controlling the terminal device to establish a TCP (Transmission Control Protocol) connection with a server through a WiFi network; the second control module is used for controlling the terminal device to send an IP (Internet Protocol) data message to the server through the WiFi network; the judge module is used for judging whether the terminal device receives ACK (Acknowledgement Character) acknowledgement message returned by the server according to the IP data message in a first transmission time delay or not; the first transmission time delay is less than a default transmission time delay in the TCP connection; the third control module is used for resending the IP data message to the server through a LTE (Long Term Evolution) network when the terminal device does not receive the ACK acknowledgement message returned by the server according to the IP data message in the first transmission time delay. This invention further discloses a method for controlling data transmission. By adopting the terminal device and the method provided bythe invention, the terminal device can keep a preferable transmitting speed without a congestion control.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a terminal device and a data transmission control method. Background technique [0002] With the development of communication technologies, more and more users use wireless terminals to access networks, and WiFi networks are one of the main wireless access networks. The biggest advantage of WiFi networking is that it operates on unlicensed spectrum, anyone can deploy a WiFi network, and it can support almost any smart handheld device or Internet of Things device that one can think of. However, due to the openness of the WiFi network, its channel competition is fierce and the packet loss rate is relatively high; in addition, the transport layer of the network mainly uses the TCP protocol. Due to the limitation of the TCP retransmission strategy, when the packet loss rate of the network is high , the terminal will perform congestion control to greatly reduce the dat...
