Method for realizing power communication slice selection and trusted transmission based on 5G network

Abstract

The invention belongs to the technical field of power communication, and particularly relates to a method for realizing power communication slice selection and trusted transmission based on a 5G network. The method comprises the following steps that a power terminal is registered to a 5G network; the power terminal registered to the 5G network sends the data to different 5G network slices; and selection algorithm matching is performed on the slices at a receiving end according to the type of the data packet until the slices are received or discarded. According to the invention, the transmission reliability of the relay protection data in the 5G network can be improved, the standard that the transmission reliability is far higher than 99.999% is achieved, the high time delay occurrence frequency of the power data transmitted in the 5G wireless network is reduced, the 5G wireless network can meet the requirements of communication between relay protection terminals for time delay and packet loss rate, a wired communication bearer relay protection service is replaced, the deployment cost and the operation and maintenance difficulty are reduced, the network utilization efficiency is improved, network resources are utilized to the maximum extent, and meanwhile safe operation of electric power communication is improved.

Description

technical field [0001] The invention belongs to the technical field of electric power communication, and in particular relates to a method for realizing power communication slice selection and trusted transmission based on a 5G network. Background technique [0002] Rich vertical industry applications in the 5G era will bring more diverse demands on mobile networks. Ultra-high bandwidth, ultra-low latency, and ultra-large-scale connections will change the operation mode and operation mode of the core business of the power industry, and comprehensively improve the traditional power industry. It is against this background that network slicing emerges in terms of operational efficiency and intelligent decision-making. Create a "dedicated" network for different applications with agility and customizable capabilities.

AI Technical Summary

Problems solved by technology

[0007] 1. High reliability requirements and high requirements for packet loss in the network;

[0008] 2. The network delay requirement is high, represented by the power relay protection terminal, there will be alarms and other measures outside the delay range

[0009] 3. There are many devices and a large amount of data, especially the data of the control signal is relatively large on the same wireless access side

[0010] The 5G network will be widely used in electric power communication due to its low latency and large bandwidth. However, due to problems such as the air interface environment, scheduling mechanism, and return path, there will be a certain frequency of high latency.

At present, most patented technologies only solve the problem of reliable transmission, and most of them are sacrificing network bandwidth to copy and backup multiple transmission data to ensure the reliability of slices; however, in the case of limited bandwidth and large amount of transmitted data per unit time In this case, it is necessary to develop a method that can dynamically adjust the priority of slice transmission matching data
