Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communication networks use traditional handover methods based on basic signal strength, then device handover between access nodes can be performed, but the network cannot effectively utilize radio signal levels to control wireless network slice usage or efficiently handover devices between slices
Solution Approach 1:
The patent applies parameter changes by monitoring specific radio signal parameters (RSRP, SINR, throughput) and using them as decision criteria for network slice selection and handover. Instead of using basic signal strength alone, the system evaluates multiple radio signal parameters against predefined thresholds to determine when to switch slices, enabling adaptive network slice usage based on actual radio conditions.
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring radio signal parameters and using this information to dynamically adjust network slice selection. The network control system receives feedback about current signal conditions and makes real-time decisions about slice handover, creating a closed-loop control system that adapts to changing radio conditions.
2Measurement precision
If the network monitors multiple radio signal parameters for slice selection, then slice selection accuracy improves, but the complexity of the control system increases
Solution Approach 1:
The patent applies segmentation by dividing the control system into distinct functional components: a monitoring function that tracks radio signal parameters, an evaluation function that compares parameters against thresholds, and a decision function that triggers slice handover. This modular approach allows precise measurement of multiple parameters while managing system complexity through functional separation.
Solution Approach 2:
The system uses dynamics by implementing configurable thresholds and monitoring parameters that can be adjusted based on network conditions and service requirements. The control system adapts its behavior dynamically, changing which parameters are monitored and what thresholds apply, rather than using fixed rigid control logic.
Data Source
AI summary
A data communication system selects an original wireless network slice for a wireless communication device. The data communication system identifies one or more radio signal parameters for the original wireless network slice. The data communication system determines one or more radio signal levels for the wireless communication device. The data communication system selects a different wireless network slice for the wireless communication device in response to the one or more radio signal parameters for the original wireless network slice and the one or more radio signal levels for the wireless communication device.
