Appendix I

Living list on Common IMT-2020 Network Architecture Diagram
(This appendix does not form an integral part of this Recommendation.)

The following I.X clauses provide four different inputs discussed for the common architecture framework
during FG IMT-2020 work. Even though they were the basis for the discussion concerning the consolidation
of the Clause 5.1 and related contents. It was agreed to keep them in this living list for further consideration
purpose.

I.1 Living list document #1 - Common architecture framework proposed in
[b-ITU-T IMT-I-225]
NOTE – Following is the proposed text for IMT-2020 network architecture framework in [b-ITU-T IMT-I-225].
For more details of the proposal, refer to [b-ITU-T IMT-I-225].

I.1.1 General framework and architectural principles
IMT-2020 shall provide converged network-computing capabilities to enable variety of services including
eMBB, massive IoT, autonomous vehicles, tactile Internet, etc. The scope of the IMT-2020 includes not only
mobile technologies but also fixed communication, cloud, and services. Accordingly, IMT-2020 is defined as
systems, system components, and related aspects that support far more enhanced capabilities than those
described in IMT-2000.

Figure 5-1 – General framework of IMT-2020 architecture
Figure 5-1 shows the general framework of IMT-2020 architecture.

For IMT-2020, there is an increased need on service customization by the service providers whereby some of
them will offer their customers the possibility to customize their own services through service related APIs
(Application Programming Interfaces) in order to support the creation, provisioning and management of
services. IMT-2020 will allow the provisioning of both existing and new services independently of the network
