Since communicating an initial set of Architecture Principles to 3GPP TSG WG2 in November 2016 the NGMN Requirements and Architecture (P1) E2E Architecture Framework group has developed their End-to-end Architecture Framework document further. Given the relative timescales of the project and of SA2’s work item for the 5G Architecture - Phase 1 it has been decided to share an interim version of the NGMN Architecture Framework document in order for SA2 to become aware of the additional principles agreed thus far, and to see the full scope of the activity.
NGMN operators believe that a Service-Based Architecture (SBA), characterized by modularized services and lightweight interaction protocols, is suitable for a 5G architectural framework. The SBA approach provides a variety of benefits for the 5G architectural framework, e.g. flexible and adaptable network capabilities, faster development cycles, updates, and a dynamic discovery and launch of services on demand in the network. NGMN acknowledges that 3GPP is working on the normative phase of a Service-Based architecture for 5G, with an emphasis on the control plane for the R15 time-frame. NGMN operators kindly recommend that 3GPP takes NGMN operators’ requirements into account and defines the 5G baseline architecture using the SBA approach. NGMN operators expect that SA2 will develop the SBA approach for the 5G system in Release 15 and continue to enhance the SBA approach beyond Release 15. Furthermore NGMN operators kindly request CT3/CT4 to work on the appropriate protocol design for the Service-Based Interfaces in Release 15.
Liaison Statement from NGMN Alliance to 3GPP on Test of Technology Building Blocks phase of the Trial and Testing Initiative
NGMN Trial and Test Initiative / Test of Technology Building Block work has led to identify a set of building blocks as promising candidates for 5G NR (New Radio) Phase 1 standardization and/or implementation activity. This set can be found in the attached document which was sent to 3GPP via a liaison letter.
With reference to IPR, NGMN is developing recommendations and an implementation strategy supporting a more transparent and predictable IPR eco-system for 5G Standards Essential Patents (SEP) across industries that will support sustainable implementation of 5G technologies and ensure that innovation is stimulated and innovators appropriately rewarded. One of the business objectives is to make 5G accessible for all types of devices from high-end smartphones and tablets down to low-end MTC (Machine Type Communication) devices such as smoke detectors and sensors. In support of this objective, the IP licensing terms and conditions for 5G market should be fair, reasonable and non-discriminatory so as to enable sustainable and successful mass deployment of any 5G service or Product Type including MTC devices to support the Internet of Things (IoT). One of the objectives is to improve the transparency of 5G Standard Essential Patent (SEP) Disclosures. NGMN sent a liaison statement to various industry organisations on this matter.
