UAV Flight Path Timestamp Signaling for Efficient Base Station Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cellular networks lack a technical solution for obtaining flight path information of UAVs, which affects the quality of service provided to unmanned aerial vehicles.
Innovation Solution
The UAV transmits timestamp indication information through RRC signaling to enable the base station to determine whether flight path information includes timestamp information, allowing the base station to decide if timestamp information reporting is necessary, thereby improving reporting efficiency and conserving resources and signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UAV always reports timestamp information with flight path information, then the base station can obtain complete flight data for extraction and switching preparation, but the signaling overhead and resource consumption increase
Solution Approach 1:
The patent implements dynamic reporting where the UAV adjusts whether to include timestamp information based on real-time service requirements. The base station sends configuration information indicating whether timestamp reporting is needed, and the UAV dynamically switches its reporting behavior accordingly, rather than always or never reporting timestamps.
Solution Approach 2:
The patent changes the parameter of timestamp inclusion in flight path information reporting based on service type. When extraction and switching preparation is needed, timestamps are included; when not needed, timestamps are excluded. This parameter change optimizes the balance between information completeness and signaling overhead.
2Productivity
If the base station requires timestamp information for all UAVs, then real-time flight data can be obtained for extraction and switching, but unnecessary resource consumption occurs for UAVs not requiring such service
Solution Approach 1:
The patent applies local quality by providing different reporting requirements to different UAVs based on their specific service needs. The base station sends configuration information to individual UAVs indicating whether they should report timestamp information, ensuring that only UAVs requiring extraction and switching preparation service consume the additional resources for timestamp reporting.
Solution Approach 2:
The patent uses partial action by having only those UAVs that require extraction and switching preparation service report timestamp information, rather than all UAVs. This partial reporting approach ensures real-time data availability for needed services while avoiding unnecessary resource consumption from UAVs that don't require such processing.
3Loss of energy
If the UAV reports flight path information without timestamp indication, then signaling overhead is reduced, but the base station cannot determine whether timestamp information is included
Solution Approach 1:
The patent implements feedback by having the UAV send timestamp indication information to the base station along with flight path information. The base station uses this indication to determine whether timestamp information is included and accordingly decides whether to send configuration information requesting timestamp reporting, creating a closed-loop feedback mechanism that optimizes signaling.
Solution Approach 2:
The patent applies preliminary action by having the UAV proactively provide timestamp indication information before the base station needs to process the flight path data. This preliminary indication allows the base station to prepare appropriate configuration information and processing steps in advance, improving overall system efficiency.
