5G Orchestration and Management

Abstract

Abstract 5G ushers in great opportunity and enables a wide spectrum of services to become available, more efficiently and effectively than ever before. Operational management of the 5G network is crucial in order to fully achieve all that is intended. Management and orchestration are two crucial focus areas of the overall 5G network management framework. Management deals with overseeing and controlling 5G network functions and services from the perspective of their expected functionality and performance. Whereas orchestration deals with realizing and adapting 5G network functions and services from the virtualization perspective. ETSI ISG NFV defines the 5G orchestration framework, while 3GPP defines the orchestrated components and data model, as well as all 5G management. NFV plays a vital role in 5G network management and orchestration. It has been considered one of the building blocks of the 5G network. NFV enables the virtualization of multiple functions and resources in the network. Specifically, NFV enables 5G network slicing, allowing various virtual networks to run on top of a single, physical infrastructure. Management and orchestration of 5G networks and network slicing are features that include the following work aspects in 3GPP standards: the management concept and architecture, provisioning, network resource model, fault supervision, assurance and performance management, trace management, and virtualization management aspects. With this focus, the 3GPP SA Working Group 5 (SA5) specifies management interfaces in support of 5G networks and network slicing. An operator can configure and manage the mobile network to support various types of services enabled by 5G, for example eMBB (enhanced Mobile Broadband) and URLLC (Ultra‐Reliable and Low Latency Communications), depending on the different customers' needs.
