Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G systems lack efficient mechanisms for managing and configuring 5G Local Area Network (LAN) groups, service discovery, and communication within these groups, particularly in enterprise environments, leading to complexities in private communication setups and security.
Innovation Solution
The implementation of configuration parameters distributed by the Policy and Charging Function (PCF) to User Equipment (UE) via NAS signaling for 5G LAN-type services, allowing users to request and configure private IP or Ethernet networks, including QoS, IP addresses, and security settings through a logical Application Function, simplifying the setup process and enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual configuration methods are used for 5G LAN groups, then flexibility in customization is improved, but device complexity and setup time increase
Solution Approach 1:
The patent introduces a PCF (Policy and Charging Function) as an intermediary that automatically distributes configuration parameters to UEs for 5G LAN services. This mediator handles the complex configuration tasks centrally, reducing individual UE complexity while maintaining configuration flexibility through standardized parameter distribution.
Solution Approach 2:
The system enables UEs to automatically receive and apply configuration parameters for 5G LAN services without manual intervention. The PCF autonomously manages parameter distribution, allowing the system to self-configure 5G LAN groups while maintaining adaptability through standardized interfaces.
2Ease of operation
If automated configuration parameters are distributed by PCF, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The PCF acts as a centralized intermediary that simplifies UE operation by automatically distributing configuration parameters. While this adds architectural complexity at the network level, it significantly improves ease of operation at the UE level by eliminating manual configuration requirements.
Solution Approach 2:
The patent segments the configuration management function into a dedicated PCF component that handles parameter distribution separately from UE operations. This segmentation isolates complexity in the network infrastructure while keeping UE operations simple and automated.
3Reliability
If private network access is enabled for 5G LAN services, then communication security is improved, but device complexity increases
Solution Approach 1:
The PCF serves as a security intermediary that centrally manages authentication and authorization for private network access. This approach enhances communication security through centralized control while reducing individual UE complexity by handling security management at the network level.
4Productivity
If configuration parameters are distributed through NAS signaling, then productivity is improved, but loss of information increases
Solution Approach 1:
The automated parameter distribution through NAS signaling enables UEs to self-configure 5G LAN services rapidly without manual intervention, significantly improving setup productivity. The standardized parameter format and automated validation reduce configuration errors, minimizing information loss despite the speed of automated deployment.
