Design and Implementation of 3GPP NTN Protocol Simulation Platform Based on NS-3

Key Points

• The aim is to design a simulation platform that addresses the limitations of existing tools for NTN.
• Developed a specialized mobile model for dynamic nodes like satellites.
• Extended the NS-3 NR module’s RRC layer according to 3GPP TS 38.331 standard.
• Implemented a complete NTN protocol stack from physical to application layer.
• Conducted experiments to evaluate end-to-end simulation performance.
• The platform accurately simulates satellite dynamics and propagation delays.
• Supports comprehensive end-to-end simulation.
• Provides essential tools for research on 6G NTN technologies.
