TEAM : 5G-Advanced Non-Terrestrial Network Dev Team

Key Responsibilities :

Developed a slimmed-down version of Huawei's 5GC for satellite scenarios with limited CPU and memory resources by:

• Optimizing the Inter-Process Communication between AMF and SMF for improved efficiency.
• Designing lightweight AUSF and UDM components for resource-constrained environments.

Key Achievements :

• Reduced CPU and memory consumption by 90% for the 5GC control plane, enabling simultaneous access for up to 15,000 users in satellite scenarios with limited resources.
• Decreased user PDU session establishment time by 60%, significantly enhancing system responsiveness and user experience.

TEAM : 5G-Advanced Communication and Sensing Integration Dev Team

Key Responsibilities :

Developed Low-altitude Security Modules to detect unauthorized drones by:

• Developed Low-altitude Security Modules to detect unauthorized drones by leveraging radar-collected point cloud data.
• Utilized Point RNN to process point cloud data and generate trackers for identifying suspicious targets.
• Designed and implemented software to control security cameras for capturing images of detected targets.
• Trained and deployed an object detection model to accurately classify detected targets as drones.
• Developed an algorithm to enhance the target detection AI model, improving its accuracy and performance.

Key Achievements :

• Achieved a solution that detects 99% of drones with a low false alert rate of just 1%.
