Solution Overview
Problem
Current 5G networks face challenges in managing the geospatial mobility of unmanned aerial vehicles (UAVs) due to high speeds and the need for seamless handoffs between nodes, which can lead to service disruptions and increased latency.
Innovation Solution
A system and method that utilize a 5G network management tool to generate a mapping between a UAV designator and geospatial region designators, instantiate a network slice, and generate a flight path for the UAV, thereby enabling seamless transit without the need for mobility registration updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If UAVs move at high speeds through 5G networks, then data transmission speed is improved, but service disruptions and latency increase due to frequent handoffs between nodes
Solution Approach 1:
The system performs preliminary actions by pre-establishing flight paths and pre-configuring handoff parameters before the UAV actually needs to switch nodes. The network management tool proactively identifies upcoming handoff points and prepares the necessary network resources and routing configurations in advance, eliminating the need for reactive mobility registration updates during high-speed transit and preventing service disruptions.
2Reliability
If mobility registration updates are performed for each handoff, then network connectivity is maintained, but additional communications traffic and latency are generated
Solution Approach 1:
The system merges multiple separate mobility registration updates into a single pre-established flight path configuration. Instead of treating each handoff as a separate registration event that generates individual communication traffic, the system combines all handoff requirements into one预先 established route, allowing the UAV to transit through multiple nodes without triggering repeated registration protocols, thus reducing communications traffic and latency while maintaining connectivity.
3Adaptability or versatility
If frequent mobility registration updates are executed, then handoffs are supported, but service disruptions occur during the update process
Solution Approach 1:
The system executes preliminary actions by pre-establishing complete flight paths and handoff sequences before the UAV reaches the handoff points. This allows the network to maintain service continuity during high-speed UAV transit by having all handoff configurations ready in advance, eliminating the need for disruptive real-time registration updates and ensuring seamless service delivery throughout the flight path.
