Solution Overview

Problem

Industrial configuration software lacks the ability to interact with the control plane of 5G networks, resulting in the inability to perform data exchange based on pre-configured quality requirements.

Innovation Solution

A data interaction method for programmable logic controllers that involves generating a parsed tag from a configuration file, acquiring subscription data from a UDM network element based on a UE's IP address, determining consistency of quality requirements, and sending modification requests to align the UE's quality requirements with those in the UDM network element, thereby modifying the PDU session to ensure data interaction based on pre-configured quality requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If industrial configuration software is used to create applications graphically, then ease of operation is improved, but the ability to interact with 5G control plane and enforce quality requirements deteriorates

Engineering Contradiction:
Improveease of application creationVSAvoidability to interact with 5G control plane
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

A network element is introduced as an intermediary between the industrial configuration software and the 5G control plane. This network element receives quality requirement information from the configuration software, stores it in a database, and uses it to modify PDU sessions, thereby enabling indirect interaction between the configuration software and the 5G control plane while maintaining the graphical configuration approach

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system is segmented into distinct functional components: the industrial configuration software for graphical application creation, a network element for managing quality requirements, a database for storing requirement information, and network functions for executing modifications. This segmentation allows each component to specialize in specific tasks while working together to achieve overall system functionality

Inventive Principle:
Principle #1Segmentation

2Reliability

If quality requirement information is stored and modified through network elements, then data exchange quality is improved, but device complexity increases

Engineering Contradiction:
Improvedata exchange qualityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The network element is designed with multi-functionality, serving as a bridge between the configuration software and control plane, a database management system, and a session modification controller. By consolidating these functions into a single network element, the system achieves improved data exchange quality while minimizing the increase in overall system complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A data interaction method and apparatus for a programmable logic controller, and an electronic device are provided. The method includes: generating a parsed label by parsing a configuration file of a target application; acquiring subscription data of a UE from a UDM network element based on an IP address of the UE in the parsed label; determining whether preconfigured first quality requirement information of the UE is consistent with second quality requirement information in the subscription data of the UE; and sending a modification request for the subscription data of the UE to the UDM network element in a case that the first quality requirement information is inconsistent with the second quality requirement information, such that the UDM network element modifies the second quality requirement information based on the first quality requirement information of the UE, and modifies a PDU session of the UE using an SMF network element.
