论文摘要
网络切片是将网络功能从一个尺寸隔离的手段，适合所有尺寸到一组不同的切片，其中每个切片负责特定的网络要求。从同一角度来看，微功能器概念的目标是用于垂直特定服务的5G局部部署。当在访问和核心网络上创建网络切片实例（NSI）时，重要的是要了解如何将创建的Slice实例的通信服务分发给不同的租户及其最终用户。在这种情况下，我们为本地5G微型操作员部署方案提供了网络切片通信服务分配技术。这是通过扩展或利用3GPP定义的通信服务管理功能（CSMF）来实现的。我们进一步描述了通信服务编排如何解决在将网络切片实例分配给多个租户期间可能存在的所有可能存在的多型套件情况。本文介绍的通用技术将提供可研究的解决方案，不仅可以通过不同的微型操作员租户进行网络切片通信服务分布，而且为支持将来的用例铺平了道路，尤其是当分配的切片负责多个租户或租户要求多个NSIS时
Network slicing is the means of logically isolating network capabilities from a one size fits all to a set of different slices where each slice is responsible for specific network requirements. In the same light, the micro-operator concept is targeted at local deployment of 5G for vertical specific services. When a network slice instance (NSI) is created across the access and core networks, it is important to understand how the communication service from the created slice instance will be distributed to different tenants and their end-users. In this vein, we propose a network slice communication service distribution technique for local 5G micro-operator deployment scenarios. This is achieved by expanding or leveraging the communication service management function (CSMF) defined by 3GPP into a multi-tenant manager and a communication services orchestrator. We further describe how the communication service orchestrator will address all the possible multitenant-slice situations that can exist during the distribution of a network slice instance to multiple tenants. The generic technique introduced in this paper will proffer a researchable solution for not only network slice communication service distribution across different micro-operator tenants but pave the way to support future use cases especially when the allocated slice is responsible for multiple tenants or when a tenant requests multiple NSIs
