Geographic NRF Request Routing for Local Network Function Discovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless network technologies do not account for the geographic location of network functions (NFs) when rerouting discovery requests, leading to inefficient resource usage and increased processing time.
Innovation Solution
Implement a system where regional Network Repository Functions (NRFs) synchronize location information with a root NRF, enabling intelligent rerouting of discovery requests to geographically proximate NFs, using locality values to prioritize regional NRFs based on available NFs matching the preferred locality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If root NRF reroutes discovery requests without considering geographic location, then routing simplicity is maintained, but resource consumption increases and processing time is extended
Solution Approach 1:
The system performs preliminary actions by having regional NRFs synchronize locality information about NFs with the root NRF in advance. This pre-synchronization of geographic data enables the root NRF to make intelligent routing decisions without real-time complexity, resolving the contradiction between routing simplicity and processing efficiency
Solution Approach 2:
The invention changes the routing parameter from simple regional NRF identification to inclusion of locality values and geographic matching criteria. By modifying the routing parameters to include locality information, the system achieves faster, more efficient routing while maintaining manageable complexity through structured parameter organization
2Loss of energy
If root NRF uses geographic intelligence to route to geographically proximate NFs, then resource consumption is reduced and network performance is optimized, but system complexity increases due to locality tracking
Solution Approach 1:
The system applies local quality by associating specific locality values with regional NRFs and NFs, enabling geographically-aware routing. Each regional NRF is characterized by its locality attributes, allowing the root NRF to match requests with geographically proximate resources, reducing resource consumption while maintaining manageable complexity through localized attribute assignment
Solution Approach 2:
The root NRF acts as an intermediary that mediates between discovery requests and regional NRFs by evaluating locality information. It uses the pre-synchronized locality data to intelligently select the most appropriate regional NRF, achieving resource optimization without requiring complex geographic calculations at every node
3Productivity
If regional NRFs synchronize locality information with root NRF, then routing efficiency is improved, but data synchronization overhead increases
Solution Approach 1:
The system extracts only the essential locality information (locality values) from the complete NF registration data and synchronizes only this specific subset with the root NRF. By taking out and transmitting only the necessary geographic attributes rather than complete NF profiles, the system achieves routing efficiency while minimizing data synchronization overhead

AI summary
A regional NRF may register NFs, and the registration information may include locality information for each registered NF. During synchronization with a root NRF, the regional NRF provides the locality information for each registered NF. During discovery request routing by the root NRF, the root NRF prioritizes regional NRFs having NFs that satisfy the discovery parameters of the discovery request and match the preferred locality indicated in the discovery request.
