Solution Overview
Problem
Unmanned Aerial Vehicles (UAVs) face challenges in reliable communication and accurate control due to interference from other wireless networks, especially when operating in unlicensed frequency bands, leading to potential loss of supervision and control.
Innovation Solution
A method where a UAV sends an access message with its type identifier to a base station, allowing the base station to acquire and apply target supervision strategy information, ensuring flight compliance with supervision requirements through a cellular network communication, reducing interference and enhancing control accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If UAV communicates using unlicensed frequency band (e.g., 2.4GHz), then communication cost is reduced and accessibility is improved, but communication reliability deteriorates due to interference from other wireless networks
Solution Approach 1:
The patent introduces a base station as an intermediary device between the remote controller and the UAV. The base station receives control signals from the remote controller and forwards them to the UAV, while also receiving telemetry data from the UAV and relaying it to the remote controller. This intermediary architecture isolates the UAV from direct exposure to interfering wireless networks, as the base station operates on a dedicated licensed frequency band that is immune to such interference, thereby maintaining communication reliability while preserving the benefits of UAV operation in unlicensed bands.
2Adaptability or versatility
If UAV operates in unlicensed frequency band, then deployment flexibility is improved, but control accuracy deteriorates due to signal interference
Solution Approach 1:
The base station serves as a mediator that ensures accurate transmission of control signals and telemetry data. By operating on a licensed frequency band, the base station provides a stable and interference-free communication channel, ensuring that control commands from the remote controller are transmitted accurately to the UAV and that telemetry data from the UAV is received without corruption. This resolves the contradiction by maintaining deployment flexibility while achieving high control accuracy through the protected communication path.
3Device complexity
If direct wireless communication between remote controller and UAV is used, then system complexity is reduced, but supervision effectiveness deteriorates due to chaotic supervision environment
Solution Approach 1:
The base station acts as a supervision intermediary that receives telemetry data from the UAV (including position, altitude, and flight status) and forwards it to the remote controller or supervisory system. This architecture maintains relatively low system complexity while significantly improving supervision effectiveness, as the base station operates in a controlled licensed frequency band that is not subject to the chaotic interference affecting unlicensed bands. The base station ensures reliable data transmission for supervision purposes without requiring complex interference mitigation techniques.

AI summary
An Unmanned Aerial Vehicle (UAV) control method and apparatus, a base station and a UAV relate to the technical field of wireless communication. The method includes: receiving an access message from a UAV, the access message including a type identifier of the UAV (101); acquiring target supervision strategy information based on the access message, the target supervision strategy information indicating a flight criterion of the UAV (102); and sending a control instruction to the UAV based on the target supervision strategy information, the UAV being configured to control flight based on the control instruction (103). Abase station, when receiving the access message of the UAV, acquires the target supervision strategy information of the UAV based on the access message and controls flight of the UAV based on the target supervision strategy information, so that it is ensured that flight of the UAV meets a supervision requirement. Since wireless communication with the UAV is performed based on a cellular network, the communication process is less susceptible to interference, the communication quality is reliable. Therefore, the accuracy of controlling the UAV is improved, and effective supervision on the UAV can be implemented.
