摘要
密集部署传输节点,减少小区半径,获得更大的小区分裂增益是5G超密集网络实现容量提升目标的关键手段。本文首先介绍了5G超密集网络的含义、典型覆盖场景和面临的挑战;其次,分析了5G虚拟化网络架构;最后介绍了5G移动通信系统以用户为中心的虚拟化技术,重点介绍了小区虚拟化和终端虚拟化技术在解决移动性和干扰问题方面的优势。
Densely deploying transmission nodes, reducing the radius of the cell, and obtaining greater cell division gain are the key means of 5G mobile communication system to achieve the goal of capacity improvement. This paper firstly introduces the mean- ing, typical coverage and challenges of 5G ultra dense network; secondly, analyzes the 5G virtual network architecture; finally, intro- duces the user centric virtualization technology of 5G mobile communication system, focusing on the advantages of residential virtu- alization and terminal virtualization technology in solving mobility and interference problems.
