Problems solved by technology

However, UDP cannot guarantee the order of data packets and data packets will not be lost
In addition, because UDP does not establish a connection and the user device will not send an acknowledgment packet to the server, if the communication quality is not good, the server may not know whether the user device has received the data packet

Abstract

The invention discloses a data transmission method, data transmission user equipment and a data transmission system. The data transmission method comprises the following steps that: the user equipment accesses a server by a terminal control protocol (TCP) through a handshaking protocol and sets a TCP data transmission mode or a user datagram protocol (UDP) data transmission mode as a data transmission mode; and then the user equipment and the server transmit data in the specified data transmission mode, wherein during data transmission, the user equipment or the server determines whether to switch the data transmission mode adopted by the user equipment or the server or not according to the quality of the accessing channel.

Description

technical field [0001] The present invention relates to a data transmission method, in particular to a data transmission method for switching between UDP and TCP data transmission modes in a wireless communication environment, a user device and a data transmission system thereof. Background technique [0002] At present, quite a number of mobile phone users use mobile phones to conduct stock transactions, and these mobile phone users can inquire about the current transaction prices of various stock trading targets in real time through the mobile phones. However, real-time trading information in the stock market has the characteristics of small data volume, long continuous transmission time, high transmission intensity and high data accuracy. The real-time transaction information of the stock market transmitted through the wireless communication network may include Transmission Control Protocol (Transmission Control Protocol, referred to as TCP) / Internet Protocol (abbreviated...
