Solution Overview

Problem

Existing wireless communication systems struggle to maintain data communication quality with uncrewed aerial vehicles (UAVs) in urban aerial mobility (UAM) scenarios, particularly with legacy 5G NR devices, due to the lack of efficient binding and unbinding mechanisms between UAVs and user equipment (UEs).

Innovation Solution

Implementing a method for binding and unbinding wireless communication devices using various application protocols (NGAP, XnAP, F1AP) to manage UAV-specific features and configurations, including UE and UAV identifiers, state information, and communication indicators, within 3GPP networks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If legacy 5G NR devices are used for UAV communication, then device compatibility is maintained, but data communication quality deteriorates in urban aerial mobility scenarios

Engineering Contradiction:

Improvedevice compatibilityVSAvoiddata communication quality

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements dynamic binding and unbinding mechanisms that allow the network to adaptively associate UAVs with appropriate UE devices based on real-time communication conditions. This dynamic approach enables legacy devices to maintain compatibility while the system dynamically optimizes communication quality by binding UAVs to suitable UEs when needed, thus resolving the contradiction between device compatibility and communication reliability

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent introduces UE devices as intermediary elements between the network and UAVs. The UE acts as a mediator that can enhance communication quality for UAVs using legacy devices by providing additional processing, relay, or coordination capabilities. This intermediary approach allows legacy UAV devices to communicate effectively while maintaining compatibility with existing 5G NR infrastructure

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If binding mechanisms are implemented for UAV-UE association, then communication quality improves, but system complexity increases

Engineering Contradiction:

Improvecommunication qualityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements preliminary binding actions where UE devices are pre-associated with UAVs before communication sessions begin. This preliminary configuration reduces the complexity of real-time binding decisions during active communication, as the associations are established in advance through standardized procedures, thereby improving communication quality without proportionally increasing system complexity

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent designs the binding mechanism to serve multiple functions simultaneously: it enables communication quality enhancement, supports mobility management, and provides a framework for future service extensions. This multi-functionality reduces overall system complexity by consolidating multiple management functions into a single universal binding framework rather than requiring separate mechanisms for each function

Inventive Principle:

Principle #6Universality (Multi-functionality)
