Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing communication technologies for unmanned aerial vehicles (UAVs) do not effectively utilize cellular networks to support flight path information transmission, limiting their operational efficiency and service feasibility.

Innovation Solution

The implementation of an information transmission method where UAVs report flight path information to base stations through RRC signaling, allowing for improved network service provision by indicating available flight path data and responding to request messages for complete path information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If UAVs use fixed flight paths with pre-planned routes, then network service prediction becomes easier, but operational flexibility and real-time control capability are reduced

Engineering Contradiction:

Improvenetwork service predictionVSAvoidoperational flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies preliminary action by having the UAV store flight path information in advance before actual flight operations. The base station can retrieve this pre-stored information to predict and prepare network services, while the UAV retains the ability to modify or update its flight path when needed, thus maintaining both predictability and flexibility

Inventive Principle:

Principle #10Preliminary action

2Loss of information

If UAVs transmit complete flight path information continuously, then base station obtains comprehensive data for service provision, but communication overhead and network resource consumption increase

Engineering Contradiction:

Improveflight path information completenessVSAvoidcommunication overhead

Core Design Contradiction:

Loss of informationVSLoss of energy

Solution Approach 1:

The patent extracts only the essential flight path information that the base station needs for service provision, rather than transmitting complete continuous data. The UAV stores comprehensive flight path information locally but transmits only relevant portions to the base station, reducing communication overhead while maintaining service quality

Inventive Principle:

Principle #2Taking out (Extraction)

3Adaptability or versatility

If UAVs report flight path information on demand, then network service feasibility improves, but response time and communication latency are introduced

Engineering Contradiction:

Improveservice feasibilityVSAvoidresponse time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The UAV performs preliminary action by storing flight path information in advance and being ready to report it immediately when the base station sends a request. This pre-prepared state enables fast response without continuous transmission, reducing both communication overhead and response latency

Inventive Principle:

Principle #10Preliminary action
