Problems solved by technology

[0004] However, in practical applications, it is found that when a terminal using the TCP protocol stack accesses a high-speed network through NB-IoT, the end-to-end TCP congestion control mechanism becomes no longer reliable.
Repeated acknowledgment information may be caused by congestion, or it may be caused by the low bandwidth, high delay, and multiple retransmission characteristics of NB-IoT as an access network. At this time, the TCP congestion control mechanism cannot play a role in regulating traffic. will also increase congestion

Embodiment Construction

[0038] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined arbitrarily with each other.

[0039] The steps shown in the flowcharts of the figures may be performed in a computer system, such as a set of computer-executable instructions. Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0040] TCP provides reliable end-to-end data transmission services, roughly including:

[0041] The sending end encapsulates the IP data header of the TCP data packet through the IP layer, and then sends it to the radio link control (RLC, Radio Link Control) layer for segmentation and encapsulation into one or more RLC protocol data units (PDU, Protocol Data U...

Abstract

The embodiment of the invention discloses a data processing method and device. The data processing method comprises the following steps: monitoring the quality of a radio link; and when the quality ofthe radio link is lowered, reducing sending rate of an RLC (Radio Link Control) layer. According to the data processing method disclosed by the embodiment of the invention, when the quality of the radio link is lowered, the sending rate of the RLC layer is reduced, thereby correspondingly slowing down scheduling of data of a TCP (Transmission Control Protocol) layer or IP (Internet Protocol) layer by the RLC layer, then indirectly adjusting a real-time rate of the TCP layer to ensure that the quality of the radio link is in a relatively good state and further improving the performance of a TCP congestion control mechanism; and therefore, the transmission performance is improved.

Description

technical field [0001] Embodiments of the present invention relate to but are not limited to communication technologies, especially a data processing method and device. Background technique [0002] The Internet of Things has entered a stage of rapid development. In the Internet of Things (IoT, Internet of Things) era, there will be tens of billions of smart devices connected to high-speed networks through NB-IoT (Narrow Band Internet of Things) to transmit data. interact. Transmission Control Protocol (TCP, Transmission Control Protocol) / Internet Protocol (IP, Internet Protocol) is currently the most widely used transport layer data communication protocol in high-speed Internet. [0003] TCP provides reliable end-to-end data transmission services. After receiving the data packet, the receiving end sends corresponding confirmation information to the sending end; the TCP protocol stack at the sending end monitors whether there is congestion by detecting repeated and timed-o...
