UAV MRDC Configuration Containers for Seamless Multi-RAT Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems struggle to efficiently support unmanned aerial vehicle (UAV) multi-radio access technology (RAT) dual connectivity (MRDC) due to incomplete integration of UAV-related features in 5G New Radio (NR) specifications, leading to service disruptions during handovers and mobility management.
Innovation Solution
Implementing configuration containers for UAVs that include identification, subscription, location, and flight path information across different RATs, enabling seamless communication between network nodes and user equipment through messages like NGAP, XnAP, and RRC, facilitating efficient handover and mobility management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If 5G NR specifications are implemented without complete UAV-related feature integration, then the system can be deployed faster, but service disruptions occur during handovers and mobility management
Solution Approach 1:
The patent applies preliminary action by pre-configuring UAV-specific parameters and configuration containers before handover operations. The master node prepares UAV mobility management configurations including identification, subscription information, and flight path data in advance, so that when handover is needed, the UAV can transition seamlessly without service disruption. This resolves the contradiction by ensuring reliability through advance preparation while maintaining deployment efficiency.
2Reliability
If comprehensive UAV configuration containers are implemented across all RATs, then service continuity is improved, but system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the comprehensive UAV configuration into separate configuration containers for different Radio Access Technologies (LTE and NR). Each container holds RAT-specific parameters such as identification, subscription information, and measurement configurations. This modular approach allows the system to maintain service continuity through complete configurations while managing complexity by organizing information into discrete, manageable segments that can be processed independently during handovers.
Solution Approach 2:
The patent uses configuration containers as intermediaries between the core network and the access network during UAV handovers. These containers act as standardized data structures that carry essential UAV information (identification, subscription data, flight path) between different network nodes and RATs. The intermediary containers simplify the interface complexity by providing a uniform mechanism for information exchange, reducing the burden on individual nodes while ensuring complete configuration transfer for service continuity.
3Loss of information
If multiple communication messages are used for configuration transfer, then information completeness is improved, but signaling overhead increases
Solution Approach 1:
The patent applies merging by combining multiple configuration parameters into unified configuration containers that are transferred through standardized communication messages. Instead of sending separate messages for each configuration element (identification, subscription information, measurement parameters), the system consolidates these into single container structures that encapsulate complete UAV configurations. This reduces the total number of signaling messages while ensuring all necessary information is preserved and transferred完整地 between master nodes during handovers.
