ITU-T Focus Group IMT-2020 Deliverables 3

1 Scope
This Recommendation specifies the overview of IMT-2020 end-to-end network management and a general
architecture of IMT-2020 Network Management, a slice life-cycle management functional architecture,
management procedures and implementation scenarios.

3 Definitions

3.1 Terms defined elsewhere

This Recommendation uses the following terms defined elsewhere:
3.1.1 IMT-2020 [b-ITU-R M-2083-0]: systems, system components and related aspects that support to
provide far more enhanced capabilities than those described in Recommendation ITU-R M.1645.
3.1.2 software-defined networking [b-ITU-T Y.3030]: A set of techniques that enables to directly
program, orchestrate, control and mange network resources, which facilitates the design, delivery and
operation of network services in a dynamic and scalable manner.
3.1.3 domain [b-ETSI NFV MANO]: Administrative domain is a collection of systems and networks
operated by a single organization or administrative authority. Infrastructure domain is an administrative
domain that provides virtualized infrastructure resources such as compute, network, and storage or a
composition of those resources via a service abstraction to another administrative domain, and is responsible
for the management and orchestration of these resources.
3.1.4 network softwarization [b-ITU-T O-016]: Network softwarization is an overall transformation trend
for designing, implementing, deploying, managing and maintaining network equipment and network
components by software programming, exploiting characteristics of software such as flexibility and rapidity
of design, development and deployment throughout the lifecycle of network equipment and components,
for creating conditions that enable the re-design of network and services architectures; allow optimization
of costs and processes; and enable self-management.

3.2 Terms defined in this Recommendation
This Recommendation defines the following terms:

3.2.1 IMT-2020 Planes: A plane is a subdivision of the specification of a complete IMT-2020 system,
established to bring together those particular pieces of information relevant to some particular area of
concern during the analysis or design of the system. Although separately specified, the planes are not
completely independent; key items in each are identified as related to items in the other planes. Each plane
substantially uses foundational concepts. However, the planes are sufficiently independent to simplify
reasoning about the complete system specification.
