摘要:

在研究和标准组织的共同努力下,下一代网络的部署进程最近加快了。尽管如此,总体情况仍然不清楚,因为主要供应商和网络提供商尚未就几个关键概念的优先级和理解达成一致。网络切片是辩论的中心话题之一,预计将成为下一代网络的关键功能,提供支持各种5G用例和业务所需的灵活性。网络切片被视为网络运营商业务,为垂直行业和传统电信客户提供灵活的服务甚至基础设施。另一个关键因素是架构模块化概念,本文讨论并认为作者的基本设计原则,以建立一个灵活的网络架构原生支持网络切片。根据该概念,通常对应于现有系统中的物理网络元件的常规单片网络功能被分成以适当粒度定义的基本构建块,从而允许定义不同的逻辑架构(即,不同的网络切片)。在本文中,我们进一步讨论了一个模块化的方法,作为一个标准,以定义正确的基本构建块。定义通过这个建议的方法,一套基本的积木和相关的接口模型进行了讨论。本文最后提出了一种模块化的5G网络架构,作为下一代网络标准的候选者。

英文摘要:

The journey towards the deployment of next generation networks has recently accelerated, driven by the joint effort of research and standards organisations. Despite this fact, the overall picture is still unclear as prioritization and understanding on several key concepts are not yet agreed by major vendors and network providers. Network Slicing is one of the central topics of the debate, and it is expected to become the key feature of next generation networks, providing the flexibility required to support the variety of 5G use cases and business. Network slices are seen as network operator business, offering the possibility to provide flexible services and even infrastructures to vertical industries and classical Telco customers alike. Another key ingredient is the Architecture Modularisation concept, discussed in this paper and regarded by the authors as the essential design principle to build a flexible network architecture natively supporting Network Slicing. According to this concept, conventional monolithic network functions, often corresponding to physical network elements in the existing systems, are to split into basic building blocks defined with the proper granularity, allowing the definition of different logical architectures (i.e. different Network Slices). In this paper, we further discuss a modularisation methodology as a criteria to define the right set of basic building blocks. Defined through this proposed methodology, the set of basic building blocks and the relating interfacing model are discussed. The paper concludes by proposing a modular 5G network architecture as candidate for next generation network standards.
