Session Communication Proxy Selection via Network Repository Function Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks lack an effective method for Network Repository Functions (NRFs) to intelligently select Session Communication Proxies (SCPs), leading to inefficient data routing and communication between network elements.
Innovation Solution
The implementation of a system where SCPs generate and transfer status and location information to NRFs, which prioritize and select SCPs based on load, capacity, and geographic proximity to optimize data routing, enabling intelligent selection and efficient communication between network functions.

Engineering Contradiction Analysis
1Productivity
If NRFs use traditional discovery methods to select SCPs, then network elements can communicate through SCPs, but the selection process is inefficient and lacks intelligence
Solution Approach 1:
SCPs periodically send status information (load, capacity, location) to NRFs, creating a feedback mechanism that enables intelligent selection. The NRF uses this feedback to maintain an updated list of available SCPs and select appropriate ones based on current network conditions, transforming the traditional inefficient discovery process into an intelligent, dynamic selection system.
Solution Approach 2:
SCPs proactively register with NRFs and provide their status information before being selected for communication tasks. The NRF pre-processes this information to create and maintain a ready-to-use list of available SCPs, eliminating the need for ad-hoc discovery during communication establishment and significantly improving selection efficiency.
2Productivity
If SCPs are selected without considering status information, then communication can be established quickly, but data routing efficiency deteriorates due to uneven load distribution
Solution Approach 1:
The system incorporates multiple parameters (load, capacity, location) into the SCP selection process. The NRF evaluates these parameters when selecting SCPs, changing the selection criterion from simple availability to multi-parameter optimization. This ensures that data routing efficiency is improved by selecting SCPs with appropriate load and capacity characteristics while maintaining communication stability.
Solution Approach 2:
The patent applies different selection criteria based on local network conditions. SCPs with different status characteristics (lightly loaded vs. heavily loaded, different locations, different capacities) are selected based on the specific communication requirements. This local quality approach ensures optimal routing efficiency for each communication pair while maintaining overall network reliability.
3Productivity
If NRFs do not prioritize SCPs based on location and load, then the system is simpler to implement, but network performance deteriorates due to suboptimal routing
Solution Approach 1:
SCPs autonomously generate and send their own status information to NRFs, and NRFs automatically process this information to create prioritized lists. The system serves itself without external intervention, with the NRF continuously updating its SCP list based on received status information. This self-service mechanism improves network performance through intelligent prioritization while keeping the implementation complexity manageable through automated processing.
Data Source
AI summary
Session Communication Proxies (SCPs) generate SCP status information and/or SCP location information. A source network function selects one of the SCPs based on the SCP status information and/or the SCP location information. The source network function transfers data to the selected one of the SCPs. The selected one of the SCPs receives the data, selects a target network function, and transfers the data to the target network function. In some examples, a Network Repository Function (NRF) prioritizes the SCPs based on the SCP status information and/or the SCP location information, and the source network function selects the one of the SCPs based on the SCP prioritization.
