Abstract:
The advanced fifth generation mobile communication system (5G system) around 2025 is expected to introduce new technologies, such as virtualized Radio Access Network (vRAN) that can place base station functions on general servers, and base station function placement based on vRAN to fit the quality requirements of communication services. In order to evaluate the quality of end-to-end communication in mobile communication system, a System Level Simulator (SLS) is widely used. However, more simulation time for SLS with the advanced 5G system is required than with the 5G system. Because new technologies are added in SLS and it executed long-term and large-scale simulations are required. A reduction of simulation time for SLS is required for an effective evaluation. In this paper, we propose a software design of SLS for the advanced 5G system with RU-basis parallel processing by multiple computation nodes. Through the SLS executed on the supercomputer Fugaku, we confirmed that our proposed method can reduce SLS processing time.
