RRC UAV Flight Path Reporting for Early Handover Preparation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for reporting flight path information from Unmanned Aerial Vehicles (UAVs) to cellular network base stations are inadequate for predicting handover requirements, as they do not effectively determine and prepare for flight-related information in advance, especially for UAVs operating in dynamic flight modes.
Innovation Solution
A method and apparatus for determining and reporting flight path information using radio resource control (RRC) signaling, which includes path positioning points, flight altitude, and reporting time, allowing the base station to anticipate handovers by receiving and processing this information from the UAV, and optionally sending partial flight path data when the transmission amount exceeds a threshold to reduce energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complete flight path information is transmitted to the base station, then the base station can accurately predict handover requirements, but the transmission data amount and energy consumption increase
Solution Approach 1:
The patent extracts only the essential elements needed for handover prediction from the complete flight path information. Specifically, it transmits path positioning points (key location coordinates) and flight altitude information, while omitting redundant details. This selective extraction maintains sufficient accuracy for base station handover prediction while significantly reducing the transmission data amount and associated energy consumption.
Solution Approach 2:
The patent implements partial transmission of flight path information by sending only critical data elements (positioning points and altitude) rather than complete flight path details. This partial action approach provides just enough information for the base station to perform accurate handover prediction, avoiding the excessive energy consumption that would result from transmitting all available flight data.
2Productivity
If detailed flight path information is reported, then network handover preparation is improved, but the signaling overhead and processing complexity increase
Solution Approach 1:
The patent extracts only the critical components necessary for handover preparation from the complete flight path information. By transmitting only path positioning points and flight altitude through RRC signaling, it reduces the signaling overhead and processing complexity while maintaining sufficient data for effective handover preparation and network management.
3Speed
If flight path information is transmitted frequently, then real-time handover prediction is improved, but the energy consumption and network load increase
Solution Approach 1:
The patent extracts and transmits only essential flight path elements (positioning points and altitude) at optimized intervals rather than continuously. This approach enables the base station to perform timely handover predictions while minimizing transmission frequency, thereby reducing energy consumption and network load associated with frequent signaling.
