A method, device, chip and terminal for sending messages

Abstract

The embodiment of the present invention describes a method, device, chip, and terminal for sending messages. The method is used for a terminal, and the terminal includes a baseband processor, an application processor, and a communication interface. The method includes sending the baseband processor to The application processor reports the information of the first message, and the first message is a message to be sent discarded by the baseband processor; the application processor transmits the second message to the baseband processor according to the information of the first message. A message, the second message is the same as the first message; the baseband processor sends the second message to the network device through the communication interface. In this way, the time delay for the terminal to retransmit the message can be reduced to a certain extent, so that the data communication between the terminal and the network is smoother.

Description

technical field [0001] The present invention relates to the communication field, and more specifically relates to a method and a device for sending messages. chips and terminals. Background technique [0002] Mobile Internet access has become the main feature of the terminal, and the technical solutions used by the terminal to access the network are also constantly developing, which greatly enriches the information acquisition rate of terminal products. The TCP / IP (Transmission Control Protocol / / Internet Protocol transmission control / Internet Internet Protocol) is a connection-oriented, reliable, byte stream-based transport layer communication protocol. [0003] In the process of connecting the terminal to the network using the TCP / IP protocol, packets are often discarded (also called packet loss). The current processing method is often that the sender retransmits the data. The current processing The method relies on the feedback from the receiving end to judge whether pa...

Problems solved by technology

[0003] In the process of connecting the terminal to the network using the TCP / IP protocol, packets are often discarded (also called packet loss). The current processing method is often that the sender retransmits the data. The current processing The method relies on the feedback from the receiving end to judge whether packet loss occurs. For example, if the sending end does not receive the feedback message such as ACK sent by the receiving end within a specified period of time, it will judge that packet loss has occurred, and then resend the data including the discarded message. This solution makes the response delay of the terminal to packet loss longer, the data transmission between the terminal and the network device takes longer, and the quality of real-time communication is greatly affected.
