Problems solved by technology

However, no confirmation information is returned during the transmission process. If the receiving end does not receive the corresponding data packet, it cannot notify the sending end to resend. It is an unreliable information transmission protocol and cannot guarantee the integrity of the received data.
[0005] To sum up, in a network environment with a high packet loss rate, using TCP network transmission will lead to high delay in data transmission, and using UDP network transmission will lead to unreliable data transmission

Abstract

The invention discloses a data sending method, comprising: grouping data to be sent into packets, and assigning a data identifier to each data packet, so as to obtain a first type of data packet corresponding to each data identifier; The data packet is divided into a plurality of sub-packages and then numbered to obtain the second type of data packet corresponding to each data identifier; respectively, the first type of data packet corresponding to each data identifier uses the TCP protocol, and the second type of data packet uses the UDP protocol sent to the data receiver. The invention also discloses a corresponding data receiving method. If the receiving party first receives the first type data packet corresponding to a certain data identifier, it stops receiving the corresponding second type data packet and clears the received second type data packet. type packet. If the received second-type data packets can form a complete first-type data packet, stop receiving the first-type data packets. The invention also discloses corresponding data sending equipment, receiving equipment and data transmission system.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a data sending and receiving method, device and data transmission system. Background technique [0002] TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are two different transmission protocols. [0003] TCP is a connection-oriented protocol that provides reliable data transmission in an IP environment. The receiving end returns a confirmation message for sending each IP data packet, and retransmits the data packets that have not received the confirmation message, so as to ensure the reliability of data transmission. But this process also slows down the speed at which packets are transmitted. [0004] UDP is a non-connection-oriented protocol that sends data packets directly without establishing a connection with the other party, so its transmission speed is faster than TCP transmission. However, no confirmation information is returned during the transmi...
