研究目的
Investigating the simulation of a complete 5G network architecture using an NS3-based framework, including core, fronthaul, and LTE access segments, and proposing an algorithm for QoS service orchestration controller.
研究成果
The study successfully demonstrates the simulation of a complete 5G network architecture using NS3, including core, fronthaul, and LTE access segments. The proposed algorithm for QoS service orchestration shows potential for optimizing network resource usage and preserving performance for critical flows. Future work includes integrating 5G New Radio Node based on millimeter wave technology.
研究不足
The study is limited to 5G non-standalone architecture based on 4G LTE, and the simulation does not account for inter-SGW mobility scenarios. The control plane interactions are modeled in a simplified manner.
1：Experimental Design and Method Selection:
The study employs the NS3 simulator to model a 5G network architecture, including core, fronthaul, and LTE access segments based on the 5G Transformer model.
2：Sample Selection and Data Sources:
The simulation involves creating scenarios for different service classes (eMBB, uRLLC, mMTC) with specific user behaviors and network configurations.
3：List of Experimental Equipment and Materials:
The NS3 simulator is the primary tool used, with specific modules for LTE (LENA) and EPC modeling.
4：Experimental Procedures and Operational Workflow:
The simulation setup includes configuring network elements (eNodeBs, SGW/PGW nodes), defining user mobility models, and testing end-to-end communication.
5：Data Analysis Methods:
Performance metrics such as blocking probability for critical and background flows are analyzed to evaluate QoS management.
