Flight Path Delta Reporting for Low-Overhead WTRU Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems face inefficiencies in updating flight path information for wireless transmit/receive units (WTRUs), particularly in scenarios where previous flight paths become invalid or require updates, leading to unnecessary signaling overhead and potential interference.
Innovation Solution
Implementing partial or delta updated flight path reporting mechanisms, where WTRUs transmit indications of updated flight paths based on changes, such as invalid timestamps or waypoints, and provide partial or delta updates upon request, minimizing redundant information exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If full flight path information is transmitted whenever updates occur, then accurate flight path information is maintained, but signaling overhead increases
Solution Approach 1:
The patent extracts and transmits only the changed portions of flight path information (delta updates) rather than the complete flight path data. When flight path changes occur, the system identifies and transmits only the specific waypoints or timestamps that have been modified, removing the redundant unchanged information from the transmission stream.
Solution Approach 2:
The flight path information is segmented into discrete change events rather than transmitted as a continuous stream. The system divides the flight path data into individual waypoints and timestamps, tracking changes at each segment level, and only transmitting segments that have actually changed.
2Reliability
If frequent flight path updates are reported, then flight path accuracy is maintained, but battery power consumption increases
Solution Approach 1:
The system implements periodic monitoring of flight path changes rather than continuous transmission. Flight path information is updated and transmitted only at specific intervals when changes are detected, creating a periodic update pattern that reduces energy consumption compared to continuous reporting while maintaining necessary accuracy.
Solution Approach 2:
The system extracts and transmits only the essential change information rather than reporting complete flight path data at each update interval. By removing redundant unchanged information from each transmission, the energy required for each reporting event is significantly reduced.
3Loss of information
If complete flight path information is transmitted, then all flight path data is available, but communication interference increases
Solution Approach 1:
The patent removes redundant unchanged flight path information from the transmission stream, extracting and sending only the delta changes. This extraction process reduces the volume of transmitted data, thereby reducing communication interference while preserving the essential updated information needed to reconstruct the complete flight path.
4Quantity of substance
If delta updated flight path reporting is implemented, then signaling overhead is reduced, but system complexity increases
Solution Approach 1:
The system performs preliminary tracking and comparison of flight path parameters before transmission decisions are made. By pre-identifying which waypoints or timestamps have changed through comparison with previous states, the system prepares the delta update information in advance, simplifying the transmission process despite the added complexity of change detection.
Data Source
AI summary
Systems, methods, devices, and instrumentalities are described herein relate to partial or delta updated flight path reporting. A wireless transmit/receive unit (WTRU) may transmit a first message indicating flight path information is available. The WTRU may receive a second message including a flight path reporting configuration. The flight path reporting configuration may request the flight path information. The WTRU may transmit an initial flight path message within a third message. Based on information associated with changing from a previous flight path to an updated flight path, the WTRU may detect that a previous flight path is required to be updated with an updated flight path. The WTRU may transmit an indication that the updated flight path is available. The WTRU may receive a request for and subsequently transmit partial or delta updated flight path information.
