Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If cell-level radio resource management is used, then system simplicity is maintained, but management precision and interference control capability deteriorate
Solution Approach 1:
The patent segments a cell into multiple micro service areas based on spatial distribution and interference characteristics. Each micro service area can be independently managed for access control, allowing precise resource allocation while maintaining overall system structure. This segmentation enables fine-grained management of radio resources without requiring complete system redesign.
Solution Approach 2:
The patent applies different management strategies to different micro service areas within a cell based on their specific characteristics. Areas with high interference can use stricter access control, while low-interference areas can allow more accesses. This local differentiation optimizes resource management precision for each region without imposing uniform complexity across the entire system.
2Adaptability or versatility
If access control is relaxed to allow more user accesses, then service availability is improved, but interference level increases
Solution Approach 1:
By dividing the cell into micro service areas, the system can apply differentiated access control policies to each segment. Users in micro service areas with high interference can be restricted from accessing certain areas, while users in low-interference areas can access more freely. This segmentation enables the system to maintain high service availability while controlling interference through localized management.
Solution Approach 2:
The system implements feedback mechanisms where network nodes monitor interference levels and adjust access control parameters dynamically. When interference exceeds thresholds in specific micro service areas, the system can modify access control settings for those areas while maintaining relaxed access in other areas. This feedback loop enables adaptive balance between service availability and interference control.
3Use of energy by moving object
If mobility measurement requirement is reduced for center users, then power consumption is reduced, but location accuracy and handover performance deteriorate
Solution Approach 1:
The patent applies differentiated mobility measurement requirements based on user location within micro service areas. Users in center areas can operate with reduced measurement requirements and lower power consumption, while users at edges or in dynamic environments maintain standard measurement requirements for accurate handover. This local differentiation optimizes power consumption without compromising handover performance where needed.
Solution Approach 2:
The system dynamically adjusts mobility measurement requirements based on real-time conditions such as user movement speed, location within micro service areas, and network load. When a user is stationary or moving slowly in a stable micro service area, the system reduces measurement frequency to save power. When dynamic conditions require handover, the system automatically increases measurement activity. This dynamic adaptation balances power consumption with measurement accuracy.
