Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks face challenges in efficiently utilizing frequency resources due to fixed channel allocations, which hinder the use of channels in cells with low traffic demand and lead to inefficiencies in three-dimensional multi-layered networks combining terrestrial and non-terrestrial systems.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fixed channel allocation is used, then system stability is maintained, but frequency resource utilization efficiency deteriorates
Solution Approach 1:
The patent implements dynamic channel allocation where channels are not fixed but can be reallocated based on current network conditions. The system continuously monitors traffic demand and interference levels, then dynamically assigns channels to cells that need them most, transforming the static allocation into a flexible, adaptive process that resolves the contradiction between stability and efficiency.
Solution Approach 2:
The system changes the allocation parameters based on traffic demand and interference conditions. By adjusting which channels are assigned to which cells based on real-time parameters rather than fixed assignments, the system maintains operational stability while significantly improving frequency resource utilization efficiency through data-driven decision making.
2Ease of operation
If frequency channels are fixedly assigned on a per-cell basis, then cell operation simplicity is maintained, but channel sharing between cells with different traffic demand deteriorates
Solution Approach 1:
The patent makes frequency channels universal resources that can be shared across multiple cells rather than being dedicated to single cells. The system evaluates which cells should use which channels based on current needs, allowing the same frequency channel to serve multiple cells at different times, thereby improving adaptability while maintaining operational simplicity through automated management.
Solution Approach 2:
The channel assignment becomes dynamic rather than static, allowing cells to gain or lose channel assignments based on traffic demand. This dynamic approach enables flexible channel sharing between cells with different traffic patterns while the automated allocation process maintains operational simplicity by removing the need for manual reconfiguration.
3Productivity
If terrestrial networks evolve into non-terrestrial and terrestrial integrated networks, then network coverage and capacity are improved, but frequency resource management complexity increases
Solution Approach 1:
The patent segments the integrated network into different altitude layers (terrestrial, HAPS, satellite) and applies interference analysis specific to each layer. By dividing the complex multi-layer network management into manageable segments with standardized interference evaluation procedures, the system handles the increased network capacity requirements without proportionally increasing management complexity.
Solution Approach 2:
The system implements feedback mechanisms where interference measurements from the integrated network are continuously monitored and fed back to the channel allocation algorithm. This automated feedback loop enables the system to adapt to the complexity of non-terrestrial and terrestrial integrated networks by using real-time data to optimize frequency resource management across all layers.
