Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently selecting and managing network slices for user equipment (UE) to optimize communication performance, as existing methods lack standardized evaluation and selection criteria for network slice simultaneous registration groups (NSSRGs), leading to potential conflicts and reduced user experience.
Innovation Solution
The proposed solution involves an apparatus and method that retrieve information associated with network slice selection, determine the priority of network slice access stratum groups, and select a network slice simultaneous registration group based on this information, providing assistance to network entities for optimized UE communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple network slices are registered simultaneously without standardized selection criteria, then network slice availability increases, but system reliability deteriorates due to potential conflicts
Solution Approach 1:
The patent introduces priority values as a parameter to differentiate and manage multiple network slice registrations. By assigning priority values to each network slice access stratum group, the system can resolve conflicts systematically, ensuring that higher priority slices are selected first, thus maintaining reliability while supporting multiple slice registrations
Solution Approach 2:
The patent segments network slices into distinct access stratum groups (NSAGs) with unique identifiers and priority values. This segmentation allows the system to manage multiple network slices independently through standardized selection procedures, reducing conflicts while maintaining versatility in slice registration
2Adaptability or versatility
If network slice selection is performed without standardized criteria, then selection flexibility increases, but manufacturing precision deteriorates due to lack of consistent evaluation
Solution Approach 1:
The patent establishes standardized selection criteria based on priority values, NSAG identifiers, and S-NSSAIs. These parameters provide consistent evaluation metrics for network slice selection, ensuring that the same inputs always produce the same outputs, thereby achieving manufacturing precision in the selection process while maintaining flexibility through configurable priority assignments
Solution Approach 2:
The patent implements a feedback mechanism where the system evaluates available information (priority values, NSAG identifiers, S-NSSAIs) and uses this feedback to determine the optimal network slice registration group. This standardized feedback loop ensures consistent selection outcomes while allowing flexibility in the information that can be provided
3Measurement precision
If network slice selection uses multiple information parameters, then selection accuracy improves, but device complexity increases
Solution Approach 1:
The patent uses multiple parameters (priority values, NSAG identifiers, S-NSSAIs) to improve selection accuracy by evaluating network slices from multiple dimensions. Despite the increased number of parameters, the complexity is managed through standardized selection procedures that systematically process these parameters in a defined sequence, preventing exponential complexity growth
