Private Network Configuration Updates via Public 5G Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G networks lack a method to allow users in a public network to temporarily access non-public networks (NPNs) while ensuring only authorized terminal devices can access specific cells, necessitating updates to configuration information across networks.
Innovation Solution
A unified data management network element determines the operation mode of a terminal device based on private network information and sends updated configuration information through a public network, involving access and mobility management, policy control, and terminal device operations to facilitate access and routing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If information is stored in distributed form across multiple terminals, then data security and reliability are improved, but information access efficiency and timeliness deteriorate
Solution Approach 1:
The patent segments information into multiple pieces and distributes them across different terminals or storage locations. Each terminal holds only a portion of the complete information, which improves security by eliminating single-point access while maintaining distributed storage benefits
Solution Approach 2:
The patent introduces an intermediary mechanism (such as a coordinator node or communication protocol) that manages the retrieval and reassembly of distributed information pieces. This intermediary enables efficient access to complete information without requiring direct access to all distributed storage locations simultaneously
2Stability of the object's composition
If information is frequently updated and synchronized across distributed terminals, then data consistency is improved, but network bandwidth consumption and system overhead increase
Solution Approach 1:
The patent implements local quality by allowing different terminals to have different versions or states of information temporarily, with synchronization occurring selectively rather than uniformly. This reduces unnecessary synchronization traffic while maintaining overall data consistency
Solution Approach 2:
The patent employs periodic synchronization mechanisms where information updates are propagated at scheduled intervals or triggered by specific events rather than continuously. This periodic action reduces network overhead while maintaining acceptable data consistency levels across distributed terminals
3Adaptability or versatility
If complete information is stored at each terminal for independent operation, then system autonomy is improved, but storage redundancy and resource waste increase
Solution Approach 1:
The patent segments complete information into distributed pieces stored across multiple terminals. Each terminal stores only its allocated segment rather than complete information, reducing overall storage redundancy while enabling autonomous operation through local segment access and combination

AI summary
This application provides an information configuration method and an apparatus, to update private network configuration information through a public network. In the method, after determining an operation mode of a terminal device based on third private network information of the terminal device, an access and mobility management network element sends third updated network configuration information to the terminal device, and after determining fourth policy information based on third policy information and the operation mode, a policy control network element sends fourth updated network configuration information to the terminal device, so that the terminal device accesses a private network based on updated network configuration information, and routes application traffic based on the updated network configuration information. According to the foregoing method, the private network configuration information can be flexibly updated through the public network.
