【摘要】：伴随着移动需求的快速增长,移动无线网络在高速发展的同时,也日益严重地受到无线网络的封闭与僵化特性的制约,这将导致诸如异构无线网络难以融合互通、网络难以提供定制化的服务等问题。为了解决上述问题,该文提出了一种基于虚拟化的软件定义无线接入网结构。首先详细介绍了该结构的整体框架。其次,对其中的关键技术如SDN控制策略、虚拟化策略以及可编程策略等进行了详细设计。该结构实现了无线接入网的灵活可控制、融合可演进、开放可编程以及弹性可定制的特性。
[Abstract]:With the rapid growth of mobile demand, the rapid development of mobile wireless networks at the same time, but also increasingly seriously restricted by the closed and rigid characteristics of wireless networks, which will lead to such as heterogeneous wireless networks are difficult to integrate and intercommunicate. Network is difficult to provide customized services and other problems. In order to solve the above problems, this paper proposes a software defined wireless access network architecture based on virtualization. Firstly, the whole frame of the structure is introduced in detail. Secondly, the key technologies such as SDN control strategy, virtualization strategy and programmable strategy are designed in detail. The structure realizes the characteristics of flexible control, converging evolution, open programmable and flexible customization of wireless access network.
