UAV Flight Path Reporting for Predictive Cellular Handovers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cellular network technologies face challenges in predicting and preparing for handovers of Unmanned Aerial Vehicles (UAVs) due to their dynamic flight paths, leading to inefficiencies in data transmission and energy consumption.
Innovation Solution
A method and apparatus for reporting flight path information from UAVs to base stations using radio resource control (RRC) signaling, which determines content including path positioning points, flight speed, altitude, and reporting time, allowing the base station to anticipate handovers and optimize network resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flight path information is reported frequently and in detail to enable accurate handover prediction, then handover reliability is improved, but data transmission overhead and energy consumption increase
Solution Approach 1:
The patent extracts only the essential flight path parameters needed for handover prediction (positioning points, speed, altitude, reporting time) from the complete flight data set. By selecting and reporting only these critical parameters through RRC signaling, the system achieves reliable handover prediction while minimizing data transmission overhead and energy consumption associated with reporting unnecessary information.
2Measurement precision
If comprehensive flight path information is collected and transmitted, then handover prediction accuracy is improved, but system complexity increases
Solution Approach 1:
The patent segments the flight path information into distinct, manageable parameters including positioning points, flight speed, flight altitude, and reporting time. Each parameter is handled separately through standardized RRC signaling procedures, which simplifies the processing and transmission complexity while maintaining comprehensive coverage of all necessary information for accurate handover prediction.
3Loss of time
If flight path parameters are reported in real-time, then handover preparation time is reduced, but data transmission overhead increases
Solution Approach 1:
The patent implements periodic reporting of flight path parameters at predetermined intervals rather than continuous real-time reporting. The UAV reports its flight path information including positioning points, speed, and altitude at regular intervals, which provides the base station with sufficient data for timely handover preparation while significantly reducing the overall data transmission overhead compared to continuous monitoring.

AI summary
A method for reporting flight path information includes: determining content of flight path information of an unmanned aerial vehicle (UAV) including at least one of a path positioning point of the UAV, the flight speed of the UAV and the flight altitude of the UAV, the reporting time of the flight path information of the UAV, and the position and altitude of the UAV when the flight path information of the UAV is reported; and reporting, through radio resource control (RRC) signalling, the flight path information of the UAV to the base station. By determining the content of the flight path information of the UAV, and reporting the flight path information of the UAV to the base station by means of RRC signalling, the base station can determine flight-related information according to the content so as to prepare for handover in advance.
