1Reliability
If predictive algorithms are used to optimize trajectories of moving cells, then communication stability is improved, but computational complexity and latency increase
Solution Approach 1:
The central trajectory controller performs predictive algorithms in advance to determine optimal trajectories for backhaul and outer moving cells. By calculating future positions and communication paths beforehand, the system prepares trajectory data that can be executed with minimal real-time computation, thus improving communication stability while reducing latency during actual operation.
Solution Approach 2:
The system dynamically adjusts trajectories of moving cells based on real-time communication conditions and predictive models. The central trajectory controller continuously updates trajectory predictions as cells move and network conditions change, allowing the system to adapt to varying requirements while maintaining computational efficiency through incremental updates rather than complete recalculations.
2Area of stationary object
If the central trajectory controller manages trajectories of multiple moving cells, then coverage area is enhanced, but device complexity increases
Solution Approach 1:
The central trajectory controller is designed as a multi-functional system that simultaneously manages trajectories for both backhaul moving cells and outer moving cells, performs predictive algorithms, monitors communication stability, and optimizes coverage areas. By consolidating these diverse functions into a single controller, the system enhances overall coverage without proportionally increasing complexity, as the controller handles multiple tasks through integrated architecture.
Solution Approach 2:
The controller manages different types of moving cells (backhaul cells and outer cells) through separate management modules or algorithms, allowing independent optimization of each cell type's trajectory while maintaining overall system coordination. This segmentation enables the system to handle complex multi-cell management by breaking it into manageable sub-tasks, reducing the perceived complexity while expanding coverage capability.
3Productivity
If predictive approaches are used to compensate for network round-trip latencies, then communication efficiency is improved, but measurement precision requirements increase
Solution Approach 1:
The central trajectory controller implements feedback mechanisms where actual positions and communication performance of moving cells are continuously monitored and compared with predicted values. This feedback is used to refine prediction models and adjust trajectories in real-time, improving communication efficiency while managing precision requirements through continuous validation and correction rather than relying solely on high-precision initial predictions.
