3 ITU-T Focus Group IMT-2020 Deliverables

As identified in Phase 1 of FG IMT-2020, standardized protocol is recommended to host all components of
the network including different RATS and the fixed network. Operators can have common management
viewpoint with eNMS regardless of network technologies as shown in the figure below.

Figure 3 – Standardized network management system

By developing standardized protocol, network operator is fully aware of all network equipment status such
that it can optimize network functions without management signalling burden. In order to develop such
protocol, requirements for IMT-2020 network management system are discussed in detail.

7 eNMS requirements for IMT-2020
The objective for CMS is to provide converged network management systems for IMT-2020. By introducing
the concept of generic network models for management, it is possible to perform general management of
diverse equipment, network and services using generic information models and standard interfaces.
eNMS is intended to support a wide variety of management areas which cover the planning installation,
operations, administration, maintenance and provisioning of telecommunications networks and services.
ITU-T Recommendation M.3010 describes the scope of management through the following two main
concepts: Telecommunication Managed Areas and TMN management Services. In addition, ITU-T categorized
management info into five board management functional areas. These functional areas support the
management scope described by M.3010. They provide a framework through which the appropriate
Management Services support the public telecommunication operator’s business processes. Five
management functional areas identified to date are as follows:

– Performance management;
– Fault management;
– Configuration management;
– Accounting management;
– Security management;

In the following sections, eNMS requirements are described regarding existing requirements
(ex., ITU-T M.3010) and requirements of IMT-2020 from network perspective.
