UAV Flight Path Format Indicator for Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems for unmanned aerial vehicles (UAVs) face inefficiencies in exchanging flight path information due to the need for reencoding between different formats, such as waypoint and polygon formats, which wastes computing resources and complicates radio access network handoffs.
Innovation Solution
The system introduces a format indicator for flight path information, allowing UAVs and base stations to transmit and receive data in the desired format, reducing the need for reencoding and conserving computing resources by using the format already stored by the UAV or directly usable by the base station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If flight path information is exchanged in a fixed format (e.g., waypoint format), then the system ensures consistency and simplicity in data structure, but it requires reencoding when different formats (e.g., polygon format) are needed, which increases computational burden and resource consumption
Solution Approach 1:
The patent applies dynamics by making the flight path information format adjustable rather than fixed. The network device can dynamically request different formats (waypoint, polygon, or other formats) based on specific operational needs, and the UAV adapts by providing information in the requested format. This dynamic format selection resolves the contradiction by enabling format flexibility without requiring complex reencoding operations, as the UAV can maintain multiple format representations or generate them on-demand based on network requests.
Solution Approach 2:
The patent implements parameter changes by allowing the format parameter of flight path information to be varied according to network device requirements. Instead of being constrained to a single format, the system changes the format parameter dynamically - the network device indicates the desired format through signaling, and the UAV responds with flight path information in that format. This parameter change approach enables versatility in format selection while avoiding the computational overhead of repeated reencoding.
2Speed
If the UAV stores flight path information in multiple formats, then it can respond to various format requests without reencoding, but it increases memory usage and data storage requirements
Solution Approach 1:
The patent applies preliminary action by having the UAV prepare flight path information in the required format in advance, before the actual request is made. The UAV can pre-process and store flight path data in common formats (such as waypoint format as the primary representation), and when a format request is received, it can quickly transform or retrieve the pre-prepared data. This preliminary preparation enables fast response speeds without requiring the UAV to maintain extensive multi-format databases, thus balancing response speed with data storage requirements.
3Ease of operation
If the base station requests flight path information in a format different from what the UAV has stored, then the base station can use the information directly for its operations, but the UAV must expend computing resources to reencode the information
Solution Approach 1:
The patent implements the intermediary principle by introducing a format indication mechanism as a mediator between the base station and UAV. The base station communicates its format requirements through standardized signaling (indicating the desired format parameter), and the UAV uses this intermediary signal to determine how to prepare and transmit the flight path information. This intermediary format indication system enables the base station to operate with its preferred format while allowing the UAV to optimize its energy consumption by selecting efficient encoding or transformation methods based on the indicated format requirement.
4Productivity
If the system uses a standardized format for all flight path information exchange, then it simplifies the communication protocol and reduces processing overhead, but it lacks the flexibility to accommodate specific format requirements of different network devices or applications
Solution Approach 1:
The patent applies universality by designing a communication system that can handle multiple flight path information formats through a unified protocol framework. The format indication mechanism serves as a universal interface that accommodates different format requirements (waypoint, polygon, and other formats) while maintaining a consistent communication structure. This multi-functional approach enables the system to maintain high communication efficiency through standardized protocols while simultaneously providing the adaptability to meet specific format requirements of different network devices and applications.

AI summary
Exchange of flight path information between a mobile network and an unmanned aerial vehicle (UAV) assumes a particular format for the flight path information, usually a waypoint format. However, there are many circumstances in which the mobile network may prefer flight path information in other formats, such as polygon formats (also referred to as “flight volume formats”). Techniques and apparatuses described herein provide greater flexibility with respect to formatting requests for flight path information and encoding responses to such requests. For example, a base station may transmit a request for flight path information with a format indicator that informs a UAV of a desired format for the requested flight path information. The UAV may then provide the flight path information according to the format indicator.
