摘要
在分析传统蜂窝结构的无线接入网面临越来越多的挑战的基础上,介绍了当前移动通信系统的发展趋势和需求,分析了第五代移动通信系统(5G)的研究目标以及对未来网络的要求。针对该问题,提出了基于C-RAN的新型5G无线接入网架构,并进一步阐述了5G通信系统网络架构的潜在关键技术,包括UND、虚拟化,SDN、NFV、CDN和绿色通信,为5G网络架构研究提供参考。
Based on the analysis of the traditional cellular structure of the radio access network （RAN） which is facing more and more challenges, the development trend and demand of current mobile communication system were introduced, and the research goal and requirement for the fifth generation mobile communication system （5G） were analyzed. Aiming at solving this problem, a new type of radio access network architecture based on C-RAN was proposed. Moreover, the potential key technologies were illustrated in detail, including UDN, virtualization （software defined network and network function virtualization）, CDN and green communication. Those provide reference for 5G access network architecture research.
