Engineering Contradiction Analysis
1Reliability
If network slice-specific cell reselection is implemented, then service quality and network performance are improved, but device complexity increases due to the need for determining cell reselection threshold values based on intended network slices
Solution Approach 1:
The patent applies parameter changes by dynamically determining cell reselection threshold values based on the intended network slice. Different network slices have different service requirements, so the threshold values (such as threshold for cell reselection to neighboring cell) are adjusted according to the specific network slice being accessed. This allows the system to optimize cell reselection behavior for different service types without requiring complete system redesign.
Solution Approach 2:
The patent segments the cell reselection process into network slice-specific procedures. Instead of using a single universal cell reselection algorithm, the system divides the process into separate handling mechanisms for different network slices. Each network slice has its own threshold value determination and reselection criteria, allowing independent optimization for each slice while maintaining overall system manageability.
2Productivity
If cell reselection threshold values are determined according to intended network slice, then radio resource management efficiency is improved, but measurement precision requirements increase due to the need to measure radio quality for comparison
Solution Approach 1:
The patent implements feedback mechanisms where the user equipment measures radio quality of neighboring cells and compares it against the determined threshold values. Based on this feedback, the system automatically determines whether to perform cell reselection or not. This feedback loop enables efficient radio resource management by making data-driven decisions about cell reselection, optimizing the balance between measurement precision and management efficiency.
Solution Approach 2:
The patent makes the cell reselection process dynamic by allowing threshold values to be determined based on the intended network slice rather than using fixed values. The system dynamically adjusts measurement and reselection criteria according to current network conditions and slice requirements, enabling the radio resource management to adapt to changing conditions while maintaining appropriate measurement precision levels.
