Abstract

The invention discloses a method and system for cooperatively controlling a TCP layer, a device, a medium and a communication terminal. The method is applied to a communication terminal and comprisesthe steps that when current data transmission state parameters of an L2 layer meet preset conditions, generating a preset notification corresponding to the preset conditions, wherein the L2 layer comprises an RLC layer and an MAC layer, and the data transmission state parameters are used for representing the data transmission quality of the L2 layer; and adjusting the current data transmission state of the TCP layer to be matched with the current data transmission quality of the L2 layer according to the preset notification. According to the invention, when the current data transmission stateparameter of the L2 layer meets the preset condition, the corresponding preset notification is generated and transmitted to the TCP layer; therefore, the TCP layer can sense the current data transmission quality of the L2 layer in time and adjust the current data transmission state according to the preset notification, and the uploading and downloading throughput rate and the wireless resource utilization rate of the communication terminal are improved based on the cooperation of the L2 layer and the TCP layer.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method, system, device, medium and communication terminal for cooperatively controlling a TCP layer. Background technique [0002] TCP (Transmission Control Protocol, which is a connection-oriented, reliable, byte-stream-based transport layer communication protocol) was originally designed for wired networks, so it is the bottom layer such as LTE (Long TermEvolution, wireless data communication technology standard ) There are certain limitations in the adaptability of this kind of wireless network. For example, in the process of using LTE for dynamic upload or download, the TCP layer cannot timely perceive the underlying transmission situation, and cannot timely send and receive data according to the underlying transmission situation. Adjustment. [0003] Specifically, in the application scenario where the communication terminal is used to upload or download dyn...
