为了满足未来移动业务快速发展的需求,除了更宽的频谱带宽、更先进的无线接入技术外,5G网络还需要新型的无线网络架构。根据5G网络主要性能要求,详细分析并总结了未来5G蜂窝网络架构的主要技术特征。基于上述讨论,提出了一种基于软件定义网络(SDN)和网络功能虚拟化(NFV)技术的新型5G蜂窝网络架构,并针对5G蜂窝网络架构可能存在的问题与挑战进行讨论,为后续研究发展提供参考。
In order to satisfy the various requirements of future network services,5G system should not only broaden the spectrum bandwidth and improve the spectrum efficiency through exploiting new technologies,but also need a novel wireless network architecture. Therefore,the key features of 5G cellular network architecture based on the demands of future network were analyzed and concluded. Meanwhile,a novel 5G architecture was proposed based on the software defined networking(SDN)and network function virtualization(NFV). In addition,the problems and challenges of the proposed 5G cellular network architecture were also discussed and analyzed.
