Abstract

The next generation of mobile networks, 5G, is currently under development by the industry, academia and international standard organizations. The key drivers of 5G are to provide incomparable more capacity (1000×), extremely lower latency (sub-millisecond) and to accommodate ‘any’ type of user (e.g. machines) in the network. Software-defined networking (SDN) and network function virtualization (NFV) technologies promise to bring an unprecedented level of flexibility in resource management. This paper presents a radio frequency spectrum management framework that is suitable to programmable 5G networks, under the overarching architecture of the 5G PPP COHERENT project. It also provides description of the recent advances and up-to-date initiatives for resource management in programmable 5G networks. The core contribution consists in the design of an SDN-enabled spectrum management application (SMA), and the related abstraction models that have been developed to enable flexible spectrum management. This paper demonstrates that suitable policy and topology abstraction models are key to spectrum management and sharing process.
5G网络频谱资源虚拟化
下一代移动网络5G目前正在由工业界、学术界和国际标准组织共同开发。5G的关键驱动因素是提供无与伦比的更大容量(1000倍),极低的延迟(亚毫秒),并在网络中容纳“任何”类型的用户(例如机器)。软件定义网络(SDN)和网络功能虚拟化(NFV)技术有望在资源管理方面带来前所未有的灵活性。本文在5G PPP COHERENT项目的总体架构下提出了一种适用于可编程5G网络的无线电频谱管理框架。它还描述了可编程5G网络中资源管理的最新进展和最新举措。核心贡献包括设计支持sdn的频谱管理应用程序(SMA),以及为实现灵活的频谱管理而开发的相关抽象模型。本文论证了合适的策略和拓扑抽象模型是实现频谱管理和共享过程的关键。
