UAV Flight Mode Reporting for Timely Base Station Policy Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems fail to timely notify base stations of flight mode changes in unmanned aerial vehicles (UAVs) operating in fixed mode, preventing timely adjustments in control strategies.
Innovation Solution
A method and device for reporting flight mode changes through media access control (MAC) control elements or radio resource control (RRC) signaling, allowing UAVs to notify base stations of mode changes from fixed to dynamic or dynamic to fixed modes, enabling timely adjustments in control strategies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the UAV operates in fixed mode with pre-planned flight routes, then the cellular network can predict which base stations the UAV will pass through, but the base station cannot timely know when the flight mode changes from fixed to dynamic mode
Solution Approach 1:
The patent configures the UAV to send a flight mode change notification to the base station in advance when switching from fixed mode to dynamic mode. This preliminary notification ensures the base station is informed before the mode change takes effect, allowing timely adjustment of control strategies and resource allocation without waiting for the mode change to be detected or reported through regular communication channels.
Solution Approach 2:
The patent establishes a feedback mechanism where the UAV actively notifies the base station of flight mode changes. This feedback loop ensures the base station receives real-time information about mode transitions, enabling the network to adapt its control strategies and resource management accordingly, thus resolving the information asymmetry between the UAV and base station.
2Adaptability or versatility
If the base station uses traditional control strategies for fixed mode UAVs, then resource allocation can be optimized for predictable routes, but the control strategy becomes outdated when the UAV switches to dynamic mode
Solution Approach 1:
The patent makes the control strategy dynamic by triggering different control modes based on the UAV's flight mode. When the base station receives a flight mode change notification indicating transition from fixed to dynamic mode, it automatically switches from pre-planned route optimization strategies to real-time adaptive control strategies, ensuring the control effectiveness matches the current operational requirements.
Solution Approach 2:
The patent changes the control parameters and strategies based on the flight mode state. The base station adjusts resource allocation, scheduling priorities, and control algorithms according to whether the UAV is in fixed or dynamic mode, ensuring optimal performance and reliability for each operational scenario.

AI summary
The present disclosure relates to a flight mode report method and apparatus, a control policy change method and apparatus, an unmanned aerial vehicle, a base station and a computer readable storage medium. The flight mode report method comprises: when in a connected state, changing a flight mode from a first mode to a second mode; and sending a flight mode change notification of a UAV to a base station to notify the base station that the flight mode of the UAV is changed from the first mode to the second mode. In the embodiment of the present disclosure, a flight mode is changed from a first mode to a second mode, and the flight mode change notification of a UAV is sent to a base station, so that the base station learns that the flight mode of the UAV is changed from the first mode to the second mode, thereby providing conditions for the base station subsequently changing a control policy for the UAV in a timely manner.
