Abstract

The 5G network is designed to meet the needs of more flexible and diversified services such as Extreme Mobile broadband (eMBB), Massive Machine-Type Communication (mMTC), and Ultra-Reliable Low-Latency Communication (URLLC). The spectrum below 6GHz is insufficient to be used by the upcoming 5G services; therefore, researchers are looking to higher frequency bands, such as 6-10GHz, or even higher 20-60GHz, which belongs to extremely high frequency. The 5G transmission system is designed to comply with the concept of frontend and backend softwarization. 3GPP proposed a software-oriented network slicing technology to meet the requirements of various service scenarios more flexibly. This study used the mmWave of 20-30GHz / 30-40GHz as the experimental frequency band and used the waveform simulator, SystemVue, to generate CP-OFDM and DFT-s-OFDM waveforms. We built a flexible platform using Software-Defined Network (SDN) from end-user to the core network by integrating waveforms, mmWave, and Network Function Virtualization (NFV) to realize the versatile design of architecture and resource allocation of the 5G core network.

利用SDN构建5G业务类网络切片平台

5G网络旨在满足eMBB (Extreme Mobile broadband)、mMTC (Massive Machine-Type Communication)、URLLC (Ultra-Reliable Low-Latency Communication)等更灵活、更多样化的业务需求。6GHz以下的频谱不足以满足即将到来的5G业务的使用;因此，研究人员正在寻找更高的频段，例如6-10GHz，甚至更高的20-60GHz，这属于极高的频率。5G传输系统的设计遵循前端和后端软件化的理念。3GPP提出了面向软件的网络切片技术，更灵活地满足各种业务场景的需求。本研究采用20-30GHz / 30-40GHz毫米波作为实验频段，利用波形模拟器SystemVue生成CP-OFDM和DFT-s-OFDM波形。我们通过集成波形、毫米波和网络功能虚拟化(NFV)，构建了从终端用户到核心网的灵活的软件定义网络(SDN)平台，实现5G核心网架构设计和资源分配的通用性。
