Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual operator adjustments are made for each non-terrestrial and terrestrial operator combination, then communication control accuracy is improved, but system complexity and management burden increase
Solution Approach 1:
The patent introduces a unified link parameter calculation method that can be applied across all operator combinations (terrestrial-terrestrial, non-terrestrial-non-terrestrial, and their interconnections). The calculation framework uses universal monitoring information collection and parameter determination rules that work for any operator pair, eliminating the need for separate adjustment mechanisms for each operator combination while maintaining precise control.
2Adaptability or versatility
If flexible network optimization is implemented across multiple operators, then network adaptability is improved, but control mechanism complexity increases
Solution Approach 1:
The patent segments the control mechanism into distinct functional modules: monitoring information collection module, link parameter calculation module, and communication control module. Each module operates independently and can be applied to different operator combinations, enabling flexible network optimization across multiple operators without creating a monolithic complex control system. The segmentation allows standardized processes to be reused across different operator scenarios.
Solution Approach 2:
The patent employs dynamic link parameter calculation that adjusts communication parameters based on real-time monitoring information and operator-specific characteristics. The system calculates appropriate link parameters (such as transmission power, bandwidth, modulation schemes) by changing parameters according to the specific operator combination and current network conditions, enabling flexible optimization while using standardized calculation methodologies.
3Loss of information
If monitoring information is collected from all node groups and terminals, then communication environment awareness is improved, but information processing load increases
Solution Approach 1:
The patent implements selective monitoring where only the necessary monitoring information relevant to each specific link is collected and processed. Rather than collecting all possible data from all node groups and terminals universally, the system monitors and processes only the information needed for calculating link parameters for active communication paths, reducing unnecessary information processing load while maintaining comprehensive awareness where needed.

AI summary
A communication control system includes non-terrestrial link control means and terrestrial resource control means. The non-terrestrial link control means controls non-terrestrial communication between a non-terrestrial node group including a non-terrestrial communication station and a terrestrial node group including a terrestrial communication station. The terrestrial resource control means controls terrestrial communication between the terrestrial node group and one or more communication terminals. The non-terrestrial link control means calculates a non-terrestrial link parameter for controlling the non-terrestrial communication based on monitoring information. The terrestrial resource control means calculates a terrestrial link parameter for controlling the terrestrial communication based on the monitoring information and the non-terrestrial link parameter.
