Terminal Flight Path Reporting for 5G Mobility Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in reporting and obtaining flight path plans from terminals, particularly in 5G mobile communication systems, which are essential for supporting various services like eMBB, mMTC, and URLLC, and are not adequately addressed by existing technologies.
Innovation Solution
A method and apparatus that enable terminals to efficiently report their flight path plans to base stations and core networks by transmitting and receiving specific messages containing flight path information, including waypoints, distance, and time parameters, allowing for optimized mobility support and handover operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal transmits detailed flight path information including all waypoints, distance, and time parameters, then the base station can obtain comprehensive flight path data for accurate mobility management, but the signaling overhead and message size increase
Solution Approach 1:
The patent extracts and transmits only the essential flight path parameters (selected waypoints, distance, and time information) that are necessary for mobility management, rather than transmitting all possible flight path data. This selective extraction reduces signaling overhead while maintaining the reliability needed for accurate handover decisions.
Solution Approach 2:
The patent implements partial action by transmitting a subset of flight path information that is sufficient for mobility management purposes. The terminal sends key parameters such as selected waypoints and critical distance/time data, which provides enough information for the base station to make accurate handover decisions without the need to transmit complete flight path details.
2Loss of time
If the terminal reports flight path information frequently to ensure up-to-date mobility management, then the base station can optimize handover timing, but the signaling frequency and network load increase
Solution Approach 1:
The patent implements periodic action by having the terminal report flight path information at optimized intervals based on flight characteristics and mobility management requirements. Rather than continuous reporting, the terminal sends updates periodically when significant flight path changes occur or at predetermined time intervals, reducing network load while maintaining timely handover optimization.
Solution Approach 2:
The patent uses feedback mechanisms where the base station receives flight path information from the terminal and responds with handover decisions and parameters. This feedback loop allows the system to optimize handover timing based on actual flight path data while adjusting reporting frequency based on network conditions and mobility management needs, improving both response time and network efficiency.
3Measurement precision
If the flight path report includes precise location and timing data for multiple waypoints, then the base station can accurately predict terminal position for handover, but the message complexity and processing requirements increase
Solution Approach 1:
The patent segments the flight path information into distinct components (waypoints with coordinates, distance parameters, and time parameters) that can be processed independently. This segmentation allows the base station to analyze different aspects of the flight path separately, improving position prediction accuracy while managing message complexity through structured, modular data organization.
Data Source
AI summary
The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system for supporting a higher data transmission rate. A method performed by a terminal includes transmitting, to a base station, a first message including first information indicating an update of flight path information, receiving, from the base station, a second message requesting a flight path report, the second message including second information configuring at least one of a number of waypoints for the flight path report, a distance parameter for the flight path report, or a time parameter for the flight path report, generating the flight path report based on the second information, and transmitting, to the base station, a third message including the flight path report.
