Solution Overview
Problem
Current methods for operating unmanned aerial vehicles (UAVs) in mobile communication networks face challenges due to unnecessary control signals and communication quality degradation, leading to potential loss of control or service failures, especially when UAVs operate in areas with varying communication quality or near populated regions.
Innovation Solution
A method and apparatus are developed to optimize control signals and communication in UAVs by using a mobile communication system that includes a network configuration to minimize control signals, provide real-time network configuration updates, and ensure continuous communication, while avoiding areas that may affect other network users or cause interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UAVs operate in mobile communication networks using conventional control methods, then basic communication is established, but control signals become unnecessary and communication quality degrades
Solution Approach 1:
The patent extracts and removes unnecessary control signals from the communication system. By identifying and eliminating redundant signaling between the UAV and network infrastructure, the system reduces communication overhead and improves quality while maintaining essential control functions.
Solution Approach 2:
The patent implements dynamic adjustment of communication parameters based on UAV flight conditions, location, and network status. This allows the system to optimize control signal transmission in real-time, maintaining reliability while reducing unnecessary communications that degrade overall system performance.
2Adaptability or versatility
If UAVs operate near populated regions or in areas with varying communication quality, then service coverage is expanded, but control loss and service failures increase
Solution Approach 1:
The patent implements preliminary registration and authentication procedures where UAVs register with the network before operation and receive pre-configured communication parameters. This preliminary setup ensures reliable control connections are established before the UAV enters areas with varying communication quality, preventing control loss.
Solution Approach 2:
The patent implements continuous feedback mechanisms where the network monitors UAV location, communication quality, and operational status. Based on this feedback, the system dynamically adjusts control parameters, redirects communications through optimal paths, or alerts operators of potential control issues before they result in service failures.
3Reliability
If network configuration is optimized for UAV operations, then communication quality improves, but system complexity increases
Solution Approach 1:
The patent implements a universal registration and configuration framework that handles multiple UAV types, flight scenarios, and network conditions through a single standardized interface. This multi-functional approach improves communication quality across diverse operations without proportionally increasing system complexity, as the same core mechanisms serve multiple purposes.
