UAV Flight Path Reporting for Predictive Cellular Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cellular network technologies face challenges in predicting and preparing for handovers of Unmanned Aerial Vehicle (UAV) flight paths, as existing methods do not effectively determine the necessary flight-related information for seamless handover processes.
Innovation Solution
A method and apparatus for receiving and determining flight path information from UAVs, which includes reporting flight path details such as position, altitude, speed, and reporting time to cellular network base stations via RRC signaling, allowing the base stations to anticipate and prepare for handovers by identifying the serving base station and handover duration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If flight path information is reported with detailed content (position, altitude, speed, reporting time), then handover preparation accuracy is improved, but information transmission overhead increases
Solution Approach 1:
The patent extracts only the essential flight-related information (position, altitude, speed, reporting time) from the complete flight path data that the UAV reports to the network. By selecting and transmitting only these critical parameters needed for handover prediction, the system achieves accurate handover preparation while minimizing information transmission overhead and avoiding unnecessary data burden.
2Reliability
If the base station determines flight-related information in advance, then handover reliability is improved, but system complexity increases
Solution Approach 1:
The base station performs preliminary determination of flight-related information by using the reported flight path parameters (position, altitude, speed, reporting time) to predict future flight paths and identify target base stations before handover is actually needed. This advance preparation enables seamless handover execution while maintaining manageable system complexity through proactive rather than reactive processing.
3Measurement precision
If the UAV reports flight path information frequently, then handover prediction accuracy is improved, but energy consumption increases
Solution Approach 1:
The UAV reports flight path information periodically or at predetermined intervals rather than continuously, transmitting updates containing position, altitude, speed, and reporting time at optimized frequencies. This periodic reporting maintains sufficient accuracy for handover prediction while significantly reducing the energy consumption associated with continuous data transmission and processing.
