Abstract

Telecommunications networks are undergoing major changes so as to meet the requirements of the next generation of users and services, which create a need for a general revised architectural approach rather than a series of local and incremental technology updates. This is especially manifest in mobile broadband wireless access, where a major traffic increase is expected, mostly because of video transmission and cloud-based applications. The installation of a high number of very small cells is foreseen as the only practical way to achieve the demands. However, this would create a struggle on the mobile network operators because of the limited backhaul capacity, the increased energy consumption, and the explosion of signalling. In the FP7 project CROWD, Software Defined Networking (SDN) has been identified as a solution to tame extreme density of wireless networks. Following this paradigm, a novel network architecture accounting for MAC control and Mobility Management has been proposed, being the subject of this paper.
一种基于sdn的超密集无线网络体系结构
电信网络正在进行重大变革,以满足下一代用户和服务的需要,因此需要一种全面修订的架构方法,而不是一系列地方性和渐进式的技术更新。这在移动宽带无线接入方面尤其明显,预计该领域的流量将大幅增长,主要原因是视频传输和基于云的应用。安装大量非常小的电池被认为是实现需求的唯一可行方法。然而,由于回程容量有限、能源消耗增加和信号爆炸式增长,这将给移动网络运营商带来一场斗争。在FP7项目CROWD中,软件定义网络(SDN)已被确定为抑制无线网络极端密度的解决方案。在此基础上,提出了一种考虑MAC控制和移动性管理的新型网络架构,这是本文的主题。
