Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies for unmanned aerial vehicles (UAVs) lack an efficient mechanism to dynamically switch between operation modes and communicate mode changes to access network devices, leading to suboptimal control strategies and potential operational inefficiencies.
Innovation Solution
A method and apparatus for UAVs and access network devices to switch operation modes (from fixed to dynamic) by reporting mode changes through information sent via wireless connections, allowing the access network device to adjust control strategies accordingly, using RRC connection recovery requests and responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the UAV switches operation modes dynamically without notifying the access network device, then the UAV can respond quickly to changing conditions, but the access network device cannot adjust control strategies appropriately leading to suboptimal operation
Solution Approach 1:
The patent implements a feedback mechanism where the UAV sends operation mode indication information to the access network device after switching modes. This allows the access network device to receive real-time feedback about the UAV's operational state and adjust control strategies accordingly, resolving the contradiction between rapid mode switching and effective control.
Solution Approach 2:
The patent applies preliminary action by having the access network device pre-configure multiple control strategies corresponding to different operation modes. When the UAV switches modes and sends indication information, the access network device can immediately retrieve and apply the appropriate pre-prepared control strategy, ensuring rapid and effective response without delay.
2Reliability
If the UAV sends detailed information about operation mode changes frequently, then the access network device can maintain accurate control strategies, but unnecessary signaling messages increase communication overhead
Solution Approach 1:
The patent extracts only the essential operation mode indication information from the UAV's operational data and sends this minimal necessary information to the access network device. This selective extraction approach maintains control strategy accuracy by conveying the critical mode change information while filtering out unnecessary details, thus reducing signaling message volume.
Solution Approach 2:
The patent changes the parameter representation of operation mode information by using concise indication information rather than detailed operational parameters. This parameter transformation allows the access network device to identify mode changes and retrieve corresponding control strategies efficiently, maintaining reliability while minimizing communication overhead.

AI summary
The present disclosure provides a method for sending information, method for receiving information, apparatus, device, and storage medium. The method can include an unmanned aerial vehicle (UAV) operating in a first operation mode when the UAV is in an inactive state. Further, the method can include the UAV switching from the first operation mode to a second operation mode different from the first operation mode, and sending, by the UAV, information to an access network device, where the information being used for indicating a change of operation mode of the UAV. The method can further include determining, by the access network device, a second operation mode to which the UAV is switched according to the information, and controlling, by the access network device, the UAV by applying a control strategy corresponding to the second operation mode.
