Network Slice Access Certification Across Multiple Databases
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks struggle to optimally match terminal devices with network slices due to incomplete certification processes, particularly for niche products, and fail to consider user-related aspects, leading to suboptimal service provision.
Innovation Solution
A method and network node that utilize an access management function to perform inquiries across multiple databases to verify terminal device and network capabilities, including user credentials, ensuring comprehensive certification and slice compatibility before establishing a communication connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a closed certification process is used to control device access, then network security and control are improved, but device compatibility and service coverage deteriorate
Solution Approach 1:
The patent segments the certification process into multiple independent components: device capability verification, network slice compatibility checking, and service requirement matching. This allows the system to maintain security control while accommodating diverse device types by certifying them through separate, specialized verification paths rather than a single rigid process.
Solution Approach 2:
The patent creates a universal certification framework that can handle multiple device types and network scenarios through a single integrated system. The access management entity can perform different certification checks (radio capabilities, application requirements, network slice compatibility) within one unified process, making the system adaptable to various devices including niche products without requiring separate certification processes for each device category.
2Measurement precision
If comprehensive multi-database verification is performed, then service matching accuracy is improved, but processing time and system complexity deteriorate
Solution Approach 1:
The patent implements preliminary action by pre-storing device capability information, network slice requirements, and service parameters in separate databases before the actual attachment process. When a device seeks network access, the system quickly retrieves and compares pre-prepared information from these databases rather than performing complex real-time analysis, thereby maintaining high matching accuracy while reducing processing complexity and time.
3Productivity
If traditional single-perspective certification is used, then certification speed is improved, but service coverage and user aspect consideration deteriorate
Solution Approach 1:
The patent divides the certification process into segmented verification stages: radio capability verification, application service requirement checking, and network slice compatibility validation. Each stage focuses on specific aspects and can be executed efficiently, maintaining overall certification speed while comprehensively covering multiple service dimensions including user-related aspects that traditional single-perspective certification misses.
