Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network slice selection is performed mainly on the network side, then network control and management are simplified, but user equipment cannot dynamically select different network slices according to application requirements, resulting in poor flexibility and accuracy
Solution Approach 1:
The network slice selection process is segmented into multiple components: network side provides slice information and basic policies, while terminal side performs dynamic selection based on application requirements. This segmentation allows both simplified network control and flexible terminal-side adaptation.
Solution Approach 2:
The patent implements dynamic network slice selection at the terminal side, where the selection criteria and parameters can be adjusted in real-time based on application requirements, user preferences, and network conditions, enabling adaptive flexibility without requiring complex network-side reconfiguration.
2Measurement precision
If network slice selection is performed mainly on the network side, then network infrastructure requirements are reduced, but network slice selection accuracy for different application scenarios deteriorates
Solution Approach 1:
The network side performs preliminary actions by providing slice information, capabilities, and basic selection policies to the terminal before actual network slice selection is needed. This preliminary preparation enables accurate terminal-side selection without requiring heavy network infrastructure or real-time network-side processing.
Solution Approach 2:
The terminal device performs self-service by autonomously selecting appropriate network slices based on application requirements and received slice information, eliminating the need for complex network-side selection mechanisms while improving selection accuracy through application-aware decision-making.
3Productivity
If all application services use the same network slice, then network management is simplified, but resource utilization efficiency and network performance for different services deteriorate
Solution Approach 1:
The patent applies local quality by enabling different network slices to be selected for different application services based on their specific requirements. Each application can be assigned to an optimally matched network slice, providing tailored network performance (e.g., high bandwidth for video, low latency for gaming) while maintaining simplified overall network management through standardized selection mechanisms.
