基于SDN的5G无线异构网络研究

Research on 5G Wireless Heterogeneous Network Based on SDN

5G面临着诸多异构网系共存的局面,如何利用软件定义网络融合组网,充分发挥各网系在数据、容量和频率方面的优势成为值得研究的课题,因此提出了基于SDN的5G无线异构网络架构,利用Open Flow协议将核心网、无线接入网和移动终端紧密连接,详细阐述了主要模块的功能和工作流程,希望为未来5G网络结构提供一种研究思路。

5G will deal with the coexistence of many heterogeneous network systems, using SDN to fuse networks, making full use of the advantages of each network in terms of data, capacity and frequency are worth studying. 5G wireless heterogeneous network architecture based on SDN was proposed in this paper. The OpenFlow protocol was used to connect the core network, the wireless access network and the mobile terminal. The function and work flow of the main modules were described in detail, providing a new research idea for the future 5G network structure.
