UAV Waypoint Reporting in RRC Signaling for Network Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no effective solution for obtaining flight path information of unmanned aerial vehicles (UAVs) for mobile cellular networks to provide services, as existing methods do not adequately address how to transmit this information for network planning and service provision.
Innovation Solution
The method involves generating and transmitting Radio Resource Control (RRC) signaling carrying the number of flight path points of UAVs through RRC processing procedures, such as connection reconfiguration, reestablishment, resume, and setup, allowing for the reporting of flight path points without adding additional uplink messages, ensuring compatibility with existing mobile communication systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If additional uplink messages are added to transmit flight path information, then the completeness of flight information reporting is improved, but the device complexity and system overhead increase
Solution Approach 1:
The patent combines flight path information reporting with existing RRC processing procedures (connection reconfiguration, reestablishment, resume, setup). Instead of creating separate uplink messages, the flight path information is merged into the existing RRC signaling structures, thereby maintaining information completeness while avoiding additional message overhead and system complexity
Solution Approach 2:
The existing RRC signaling structures are made multi-functional by enabling them to carry both traditional mobile communication data and UAV-specific flight path information. This universal approach allows the same signaling mechanisms to serve multiple purposes, eliminating the need for dedicated message structures for flight information transmission
2Loss of time
If flight path information is transmitted in real-time, then the timeliness of network service provision is improved, but the use of energy and communication resources increases
Solution Approach 1:
The patent implements periodic flight information reporting by integrating it into existing periodic RRC procedures. Instead of continuous real-time transmission, the UAV reports flight path information at periodic intervals when RRC procedures are naturally triggered (connection reconfiguration, reestablishment, resume, setup), achieving timely updates while reducing overall communication energy consumption compared to continuous transmission
