UAV Cellular Control With Base-Station Connection Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
UAVs controlled via cellular networks face challenges in determining when they have established a communication connection, leading to delayed control and reduced communication quality due to the lack of timely connection confirmation with base stations.
Innovation Solution
The UAV sends connection success information to a remote control device through a base station, allowing the remote control device to determine the connection status and send control signals promptly, utilizing the cellular network's wider coverage and stability for improved communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UAV is controlled by remote control device over cellular network, then coverage and stability are improved, but connection status determination is delayed
Solution Approach 1:
The patent implements a feedback mechanism where the base station sends connection status information back to the remote control device. The network side actively feeds back whether the UAV has successfully accessed the network, allowing the remote control device to determine connection status in real-time without manual configuration or guessing.
Solution Approach 2:
The patent performs preliminary actions by having the base station prepare and send connection status information proactively. Instead of waiting for the remote control device to query or determine connection status, the network side initiates the information transmission in advance, enabling timely control resumption.
2Length of moving object
If UAV uses cellular network for control, then control distance is extended, but connection confirmation timing is lost
Solution Approach 1:
The base station acts as an intermediary that bridges the gap between UAV and remote control device. It receives access status information from the network side and transmits this information to the remote control device, enabling long-distance control while maintaining accurate connection timing information through the intermediary's information relay function.
3Device complexity
If remote control device determines connection status manually, then device complexity is reduced, but control response time increases
Solution Approach 1:
The system implements self-service by having the base station automatically obtain and transmit connection status information without requiring the remote control device to perform complex determination operations. The network side serves itself by actively providing the information, maintaining device simplicity while achieving fast response.

AI summary
An unmanned aerial vehicle control method and device, the method comprising: transmitting a random access request to a base station; after a communication connection with the base station is established, transmitting, according to the identification information of a remote control device, connection success information to the remote control device; receiving a control signal transmitted by the remote control device, the control signal being transmitted by means of the base station; and performing an operation according to the control signal. After randomly accessing a certain base station in a cellular network, the unmanned aerial vehicle can transmit the connection success information to a remote control device corresponding to the identification information of the remote control device, so that the remote control device can timely determine that the unmanned aerial vehicle has established a communication connection with the base station. And thereby, the control signal can be transmitted to the unmanned aerial vehicle by means of the base station so that the unmanned aerial vehicle can be timely controlled to perform the corresponding operation.
