Problems solved by technology

However, when the number of access users is large and the uplink business volume is large, the performance of the TCP layer will be reduced (for example, TCP transmission may be delayed or packet loss), which will lead to poor data service quality at the application layer

Abstract

The invention provides a data transmission method and device, electronic equipment and a computer readable storage medium, and the method comprises the steps: building a first TCP connection with UE when the UE sends a data message to a data network DN through a first user plane function UPF unit; receiving a data message forwarded by the first UPF unit through the first TCP connection, and establishing a second TCP connection between a TCP optimization module in a second UPF unit and the DN; and determining the sending rate of the data message based on the gain state of the TCP optimization module and the bandwidth of the second TCP connection, and sending the data message to the DN through the second TCP connection at the sending rate. According to the scheme, when the UE has an uplink service requirement, two TCP connections are established between the UE and the DN by taking the TCP optimization module as a forwarding node, so that the transmission rate of the TCP connections between the UE and the DN can be optimized through the TCP optimization module, congestion control is realized, the performance of a TCP layer is improved, and the data service quality of an application layer is further improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular, the present application relates to a data transmission method, device, electronic equipment, and computer-readable storage medium. Background technique [0002] In the existing 5G (5th Generation) network, when a user performs uplink services, the user and DN (Data Network, data network) directly establish a TCP (Transmission Control Protocol, Transmission Control Protocol) connection, which is end-to-end TCP control, and the service data The path is transmitted through UE (User Equipment, user equipment) → 5G-AN (5G AccessNetwork, 5G access network) → UPF (User Plane Function, user plane function) → DN multiple network nodes. However, when there are a large number of access users and a large amount of uplink traffic, the performance of the TCP layer is degraded (for example, delay or packet loss may occur in TCP transmission), which will lead to poor data serv...
