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

VSEngineering 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

Engineering Contradiction:
Improvehandover preparation accuracyVSAvoidinformation transmission overhead
Core Design Contradiction:
Measurement precisionVSLoss of information

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.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If the base station determines flight-related information in advance, then handover reliability is improved, but system complexity increases

Engineering Contradiction:
Improvehandover reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

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.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If the UAV reports flight path information frequently, then handover prediction accuracy is improved, but energy consumption increases

Engineering Contradiction:
Improvehandover prediction accuracyVSAvoidUAV energy consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

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.

Inventive Principle:
Principle #19Periodic action
