UAV RRC Signaling for Flight Path Information Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cellular networks lack a technical solution to obtain flight path information of unmanned aerial vehicles (UAVs), which reduces the quality of service provided to UAVs.
Innovation Solution
A method and apparatus for transmitting information, where a UAV generates designated event information indicating it has flight path information, adds this information to a message, and sends it to a base station, allowing the base station to determine the UAV's flight path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If cellular network provides service to UAVs using conventional methods, then basic communication is maintained, but the network cannot obtain flight path information of the UAVs
Solution Approach 1:
The patent embeds flight path information within existing RRC signaling messages. The UAV includes flight path information elements nested within standard RRC connection setup complete, reconfiguration complete, or other established signaling messages, allowing information transmission without adding separate communication channels or protocols.
Solution Approach 2:
The patent makes existing RRC signaling messages serve multiple functions: maintaining network communication while simultaneously conveying flight path information. The same RRC messages used for connection management are also utilized to carry designated event information and flight path data, eliminating the need for dedicated information transmission channels.
2Reliability
If the base station requests flight path information from the UAV, then the base station can obtain the information, but additional signaling messages increase communication overhead
Solution Approach 1:
The patent enables the UAV to proactively report flight path information to the base station before the network needs to request it. The UAV monitors for designated events (such as entering a service area or changing flight parameters) and automatically includes flight path information in uplink RRC messages, eliminating the need for separate request-response signaling sequences.
Solution Approach 2:
The patent establishes a feedback mechanism where the UAV continuously monitors its flight status and network conditions, then automatically provides flight path information when designated events occur. This feedback loop ensures the base station receives timely information without needing to actively query the UAV, reducing signaling overhead while maintaining information reliability.

AI summary
The present disclosure relates methods and apparatuses for transmitting information. The method is applicable to an unmanned aerial vehicle (UAV). The method includes: generating designated event information when the UAV has flight path information, where the designated event information indicates that the UAV has the flight path information; adding the designated event information to a first message; and sending the first message to a base station, such that the base station determines that the UAV has the flight path information according to the designated event information included in the first message.
