Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If empty radio waves are distributed to wireless systems, then radio resource utilization is improved, but the complexity of determining eligibility increases due to various use modes
Solution Approach 1:
The system changes the parameter of consideration from detailed use mode analysis to movement prediction range. Instead of analyzing complex use modes (mobile terminal, FPU, etc.), the system uses movement prediction range information to determine eligibility, simplifying the determination process while maintaining effective radio resource distribution
Solution Approach 2:
The determination process is segmented into separate functional components: action prediction range acquisition, position acquisition, and eligibility determination. This segmentation allows each component to handle specific aspects independently, reducing overall complexity
2Reliability
If interference protection is performed for primary systems, then primary system protection is improved, but unnecessary recalculation of interference occurs
Solution Approach 1:
The system performs preliminary action by acquiring movement prediction range information before making eligibility determinations. This allows the system to pre-determine protection requirements and avoid unnecessary recalculation of interference when terminals move within predicted ranges
Solution Approach 2:
The system uses feedback from position information and movement prediction range to dynamically adjust protection measures. When a terminal's position changes within its predicted range, the system updates eligibility status without performing complete interference recalculation, saving time while maintaining protection
3Measurement precision
If movement prediction range information is acquired, then eligibility determination accuracy is improved, but information acquisition complexity increases
Solution Approach 1:
The system introduces movement prediction range information as an intermediary parameter between position data and eligibility determination. This intermediary simplifies the relationship by providing a pre-processed prediction range that directly informs eligibility decisions without requiring complex real-time analysis

AI summary
A communication control apparatus includes: an action prediction range acquisition unit that acquires movement prediction range information indicating a range where a use terminal that performs secondary use of a predetermined frequency band is predicted to move; a position acquisition unit that acquires position information of the use terminal; a determination unit that determines whether or not the secondary use of the use terminal is possible based on the movement prediction range information and the position information, which have been acquired; and a notification unit that notifies the use terminal of determination of whether or not the secondary use is possible.
