Base Station RRC Triggers for UAV Flight Path Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned aerial vehicles (UAVs) face challenges in efficiently reporting flight path information, particularly when transitioning between flight modes, and existing cellular network systems struggle to efficiently manage this information exchange.
Innovation Solution
UAVs send notification information to a base station upon completion of specific RRC operations, allowing the base station to determine and obtain flight path information through a series of RRC signaling and configuration processes, enhancing the efficiency of reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the UAV reports flight path information frequently to ensure accuracy, then the measurement precision is improved, but the loss of time increases due to repeated reporting cycles
Solution Approach 1:
The base station performs preliminary actions by storing RRC configuration information and proactively determining when flight path information should be reported. The base station pre-establishes the reporting mechanism and triggers it based on predetermined conditions (RRC connection setup, reconfiguration, or reestablishment) rather than relying on continuous UAV initiation, thereby reducing time loss while maintaining accuracy.
Solution Approach 2:
The system implements feedback through the base station receiving notification information from the UAV upon completion of target operations, then using this feedback to determine when to obtain flight path information. This feedback loop ensures accurate information exchange while optimizing timing based on actual connection states rather than fixed intervals.
2Adaptability or versatility
If the system uses complex reporting mechanisms to handle mode changes, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The base station's RRC configuration information serves multiple functions: it stores connection parameters, determines reporting triggers, and handles different flight modes (fixed and dynamic) through a unified mechanism. The notification information structure is universal, handling both initial connections and mode changes through the same reporting framework, thereby achieving adaptability without proportionally increasing complexity.
Solution Approach 2:
The system manages different flight modes by changing parameter states rather than using fundamentally different mechanisms. The base station adjusts its behavior based on the flight mode parameter (fixed or dynamic) while using the same underlying RRC signaling framework. This allows the system to adapt to mode changes through parameter-driven logic rather than complex structural changes.
3Ease of operation
If the UAV initiates flight path information reporting manually, then the ease of operation is improved, but the productivity decreases due to delayed reporting
Solution Approach 1:
The base station performs self-service by automatically determining when flight path information should be reported based on stored RRC configuration information and connection states. The base station proactively initiates the reporting process rather than passively waiting for UAV initiation, thereby improving productivity while the UAV simply needs to send notification information upon completing target operations, which remains operationally simple.
Solution Approach 2:
The base station performs preliminary actions by pre-storing RRC configuration information and pre-determining reporting triggers before actual flight path information exchange is needed. This preliminary preparation allows the system to transition quickly from connection establishment to information reporting without manual intervention delays, improving productivity while maintaining ease of operation through automated triggers.

AI summary
A method apparatus, and a storage medium, for information transmission in a wireless communication system. The information transmission is performed by: sending notification information to a base station upon completion of a target operation, where the target operation is an operation associated with a radio resource control (RRC) connection between the unmanned aerial vehicle and the base station, and the notification information informs the base station that the unmanned aerial vehicle stores flight path information.
