Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If general handover procedure is applied in ground network environment, then handover can be performed based on signal strength thresholds, but handover errors occur due to rapid signal changes in airborne network caused by high flight speed
Solution Approach 1:
The base station determines the aircraft's movement direction and predicts future signal strength changes before actual handover is needed. By anticipating signal deterioration based on movement direction and predicted signal changes, the base station proactively initiates handover preparation in advance, preventing handover errors caused by rapid signal transitions during high-speed flight
Solution Approach 2:
The system continuously monitors the aircraft's movement direction and uses this feedback to dynamically adjust handover conditions. The base station modifies handover timing and parameters based on real-time movement information, creating a closed-loop control mechanism that adapts to varying flight conditions and optimizes handover reliability
2Stability of the object's composition
If handover is performed rapidly to maintain connection during high-speed flight, then communication continuity is improved, but handover processing complexity increases due to frequent and sudden signal changes
Solution Approach 1:
By determining movement direction and predicting signal changes in advance, the base station performs handover preparation before critical handover moments occur. This preliminary action smooths out the handover process timing, reducing the frequency of sudden handovers and thereby lowering processing complexity while maintaining communication continuity
Solution Approach 2:
The system dynamically adjusts handover conditions based on real-time movement direction information. By making handover parameters adaptive and flexible rather than fixed, the system can optimize handover timing for each specific flight condition, reducing unnecessary handovers and simplifying processing complexity
