本文探讨了5G移动通信架构中网络切片的概念、系统架构、盈利建模及其面临的挑战和研究方向。

摘要:

高效的灵活性和更高的系统可扩展性要求增强的网络性能、更好的能耗、更低的基础设施成本和有效的资源利用。为此,需要对现有蜂窝网络进行架构优化和重建。网络切片被认为是通信系统2020年以后的关键使能器和架构解决方案。传统移动运营商通过单一网络为各种客户类型提供所有类型的服务,然而,随着网络切片的部署,运营商现在能够将整个网络划分为不同的切片,每种切片都有自己的配置和特定的服务质量(QoS)要求。在基于切片的网络中,每个切片将被视为一个独立的逻辑网络。这样,基础设施利用和资源分配将比传统网络更加节能和成本高效。在本文中,我们对网络切片的概念和系统架构进行了全面讨论,特别关注其商业方面和盈利建模。我们深入讨论了两种不同的盈利建模维度,即自有切片实现和外包切片的资源租赁。我们进一步探讨了开放的研究方向和现有挑战,目的是激励新的进展并为这一新兴技术提供现实的解决方案。

英文摘要:

Efficient flexibility and higher system scalability call for enhanced network performance, better energy consumption, lower infrastructure cost, and effective resource utilization. To accomplish this, an architectural optimization and reconstruction of existing cellular network is required. Network slicing is considered to be one of the key enablers and an architectural answer of communication system of 2020 and beyond. Traditional mobile operators provide all types of services to various kinds of customers through a single network, however, with the deployment of network slicing operators are now able to divide entire network into different slices each with its own configuration and specific Quality of Service (QoS) requirements. In a slice-based network, each slice will be considered as a separate logical network. In this way, the infrastructure utilization and resource allocation will be much more energy and cost efficient in comparison to traditional network. In this paper, we provided a comprehensive discussion on concept and system architecture of network slicing with particular focus on its business aspect and profit modeling. We throughly discussed two different dimensions of profit modeling, so called Own-Slice Implementation and Resource Leasing for Outsourced Slices. We further addressed open research directions and existing challenges with the purpose of motivating new advances and adding realistic solutions to this emerging technology.
