Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional methods are used to provide PIN data to core network devices, then the system architecture remains simple, but the efficiency of providing and updating PIN policy data is low and signaling overhead is high
Solution Approach 1:
The patent introduces a network exposure function (NEF) as an intermediary between the application function (AF) and the core network devices (UDM, UDR). The NEF receives PIN policy data from the AF, processes it, and distributes it to the appropriate core network elements. This intermediary approach improves data provision efficiency while maintaining manageable system complexity by centralizing the interaction logic.
Solution Approach 2:
The patent segments the PIN data management functionality across multiple specialized network elements: AF for policy definition, NEF for data exposure and coordination, UDM for subscriber data management, and UDR for data storage. This segmentation allows each element to focus on specific tasks, improving overall efficiency while distributing complexity across modular components.
2Reliability
If PIN policy data is updated across all network elements, then data accuracy is improved, but signaling overhead increases
Solution Approach 1:
The patent enables each network element to maintain and use PIN policy data locally according to its specific functional requirements. The AF can define different policy data for different applications, the NEF can filter and route data selectively, and the UDM/UDR can store data in optimized formats. This local optimization ensures data accuracy where needed while reducing unnecessary signaling by avoiding uniform updates across all elements.
Solution Approach 2:
The patent establishes feedback mechanisms where network elements can report their data status and requirements to the NEF, which then coordinates targeted updates. This feedback loop ensures that PIN policy data is updated accurately in the right places while minimizing unnecessary signaling by avoiding blanket updates to all network elements.
3Adaptability or versatility
If multiple network elements manage PIN data independently, then system autonomy is improved, but coordination difficulty increases
Solution Approach 1:
The patent designs the NEF as a universal coordination point that handles multiple functions: receiving PIN policy data from various AFs, processing and validating the data, routing to appropriate UDM/UDR instances, and managing updates across network elements. This multi-functional intermediary maintains the autonomy of individual elements while providing centralized coordination, reducing the complexity of direct peer-to-peer coordination between multiple autonomous elements.
