PLC Data Interaction via UDM-SMF Quality Alignment
Find Innovative SolutionsGenerate Solutions
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 UE subscription data, determining consistency of quality requirements, and sending modification requests to UDM and SMF network elements to align quality requirements, thereby modifying PDU sessions to ensure data interaction based on pre-configured quality requirements.
Engineering Contradictions & Design Principles
Engineering 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
Solution Approach 1:
The patent introduces a server as an intermediary component that bridges the industrial configuration software and the 5G control plane. The server generates parsed tags from configuration files, queries the UDM network element for subscription data, and sends modification requests to enforce quality requirements. This intermediary enables the graphical configuration software to indirectly interact with the 5G control plane without requiring direct integration, thus maintaining ease of operation while gaining 5G interaction capability.
2Reliability
If subscription data quality requirement information is modified to align with pre-configured requirements, then reliability of data exchange is improved, but device complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring quality requirement information in the industrial configuration software before deployment. The pre-configured quality requirements are stored in the configuration file and parsed into tags during runtime. This allows the system to automatically compare and enforce quality requirements without complex real-time negotiations, thereby improving reliability while minimizing the need for complex runtime decision-making logic.
3Adaptability or versatility
If the server queries and modifies UE subscription data in the UDM network element, then adaptability to 5G network quality requirements is improved, but loss of time in data interaction increases
Solution Approach 1:
The patent applies the skipping principle by optimizing the query and modification process. The server queries the UDM network element for subscription data using the UE's IP address to quickly obtain identification information. When quality requirement inconsistencies are detected, the server immediately sends modification requests to the UDM and SMF network elements without unnecessary delays. This rushed-through approach minimizes the time loss while maintaining adaptability to 5G network quality requirements.

AI summary
Disclosed are a data interaction method and apparatus for a programmable logic controller, and an electronic device thereof. 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 pre-configured 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.
