Data transmission shunting method and device

Abstract

The embodiment of the invention provides a data transmission shunting method and device applied to a 5G base station in non-independent networking, and the method comprises the steps: receiving a current PDCP (Packet Data Convergence Protocol) flow value, fed back by a terminal, of the 5G base station, wherein the terminal establishes a first path with a 5G base station in the non-independent network, and establishes a second path with a 4G base station in the non-independent network; comparing the current PDCP flow value of the 5G base station with a first preset threshold value, and if the current PDCP flow value of the 5G base station exceeds the first preset threshold value, sending first congestion indication information to the 4G base station through an X2 interface; shunting the downlink transmission data of the 5G base station into first shunting data and second shunting data according to a preset shunting proportion; and transmitting the first shunt data through the first path, and transmitting the second shunt data through the second path. The embodiment of the invention can solve the problem of access congestion of the base station and improve the data transmission performance.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and device for data transmission distribution. Background technique [0002] NSA (Non-standalone, non-independent networking) aims at the control signaling of 5G (5th Generation of cellular radio, fifth-generation wireless cellular technology) at the base station of 4G (4th Generation of cellular radio, fourth-generation wireless cellular technology) Firstly, 4G base stations are connected to EPC (Evolved Packet Core, core network). The NSA solution requires 4G / 5G base stations from the same manufacturer, and terminals support dual connections. For 5G NSA networking, 4G and 5G base stations realize data transmission through dual connection technology. [0003] In the dual connection scenario, a terminal establishes a connection with two base stations at the same time, and transmits data through two channels at the same time. How to allocate data on the two...

Problems solved by technology

[0003] In the dual connection scenario, a terminal establishes a connection with two base stations at the same time, and transmits data through two channels at the same time. How to allocate data on the two channels can achieve a higher transmission rate and a lower transmission rate between the base station and the terminal. Delay is a problem that needs to be studied. If the data distribution ratio on the two channels is uneven, it may cause data congestion in one channel and waste resources in the other channel, thereby reducing the system data transmission performance.
