Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless network slices are statically assigned without RF metric monitoring, then network configuration is simple, but service quality and performance deteriorate under varying RF conditions
Solution Approach 1:
The patent implements dynamic network slice selection by continuously monitoring RF metrics (signal strength, interference levels) and automatically switching between slices based on real-time conditions. The system transitions from static slice assignment to dynamic adaptation, where the network control system evaluates RF metrics and redirects traffic to optimal slices without manual intervention, resolving the contradiction between service quality reliability and management complexity
Solution Approach 2:
The patent establishes a feedback mechanism where RF metrics are continuously collected from wireless communication devices, analyzed by the network control system, and used to adjust slice selection in real-time. This closed-loop feedback system enables automatic optimization of service quality based on actual RF conditions, balancing improved reliability with manageable complexity through automated decision-making
2Speed
If manual slice switching is implemented, then control precision is high, but switching speed and response time worsen
Solution Approach 1:
The patent implements self-service automation where the network control system autonomously monitors RF metrics, evaluates slice performance, and executes switching decisions without human intervention. The system automatically collects RF data, compares it against threshold criteria, and redirects traffic to optimal slices, achieving high switching speed while maintaining appropriate control precision through algorithmic decision-making rather than manual operations
Solution Approach 2:
The patent prepares multiple network slices in advance with predefined RF metric thresholds and performance characteristics. When switching is needed, the system has pre-configured slice information ready for immediate activation, enabling fast switching speed. The preliminary configuration of slice parameters and threshold criteria allows the automated system to make rapid decisions without requiring complex real-time calculations
3Reliability
If RF metric monitoring is continuously performed, then service optimization is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic RF metric collection at optimized intervals rather than continuous monitoring. The network control system samples RF conditions at predetermined time periods or when threshold violations are detected, achieving sufficient service optimization through periodic updates while significantly reducing energy consumption compared to continuous monitoring. This periodic action maintains service quality while balancing power usage requirements

AI summary
A wireless communication device exchanges user data to use a wireless network slice. The wireless network slice has Radio Frequency (RF) information that controls slice usage. The wireless communication device determines an RF metric for a wireless communication link. The wireless communication device or the wireless communication network process the RF metric and the RF information to select another network slice. In response to the slice selection, the wireless communication device and the wireless communication network stop the exchange of the user data to use the wireless network slice and start an exchange user data to use another wireless network slice.
