Definition of the Testing Framework for the NGMN 5G Pre-Commercial Network Trials

This document focuses on the pre-commercial network trials phase of the NGMN 5G Trial & Testing Initiative which has the following scope: Developing a testing framework for 5G New Radio (NR), as developed by 3GPP, allowing the harmonization of the testing methodologies between the different parties conducting trials. Devising a strategy for the trials activities to guarantee efficiency and success of the different trials activities. Testing 5G capabilities in realistic conditions with pre-commercial equipment.

Service-Based Architecture in 5G

In March 2017, the project on “Service-based architecture in 5G” was launched. The main target of this work group was to investigate high-level requirements, use cases and guidelines for how operators can efficiently introduce and operate a service-based 5G network, i.e., Identify high-level requirements or guidelines on Service-based architecture design in 5G including network function, interface/protocol, API design principle; Investigate how operators can leverage Service-based architecture in 5G in the best way, e.g., customized network slicing, updating and managing network feature dynamically. Samples, possible approaches and guideline are expected Investigate how the Service-based architecture can enable network exposure, e.g., expose network and function capabilities to third parties for value-added services. This White Paper calls for the industry on standardisation, development and promotion of service-based 5G architecture.

5G Extreme Requirements: Operators’ Views on Fundamental Trade-Offs

The aim of this work is to highlight what implications and trade-offs related to the delivery of new 5G services are relevant for mobile network operators. Some of these new services, in fact, require extremely low latency and high reliability of the communication link, which have very little in common with the targets that the telecommunications industry has worked towards until today. Mobile cellular networks have in fact traditionally been designed and optimised for the delivery of good voice and data services for mobile broadband customers, so the new 5G requirements now call for a re-think on how the future network will have to be designed and optimised in order to enable the new services. The purpose of this document is to outline relevant trade-offs that need to be taken into account when delivering 5G services. In particular, the interplay among coverage, packet size, data rate, latency, and reliability, is analysed.

Liaison Statement on Technology Evaluation of LTE-V2X and DSRC

The intention of the liaison statement from the NGMN V2X Task-Force to the 5GAA is to inform 5GAA of evaluation results summary on link level simulation (LLS) and system level simulation (SLS) for LTE-V2X performance compared with DSRC performance.

5G E2E Architecture Framework

The purpose of this document is to provide a high-level framework of architecture principles and requirements that provide guidance and direction for NGMN partners and standards development organisations in the shaping of the 5G suite of interoperable capabilities, enablers, and services. It builds on the architectural concepts and proposals implied by the NGMN 5G White Paper and subsequent deliverables published by NGMN. It is anticipated that this document will have versions, beyond an initial version, to reflect additional forward-looking requirements and/or updates as needed.  The elements of functional virtualisation, shift of computing to the edges of the network, and leveraging of spectrum distribution and flexibility, are among the dominant themes that shape the 5G ecosystem. Optimisation of operational and performance efficiencies, while creating and delivering an exceptional and customisable user experience is of paramount significance.

NGMN Paper on 5G End-to-end Architecture Framework

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 Submission to US Department of Transportation during NPRM Process

In this document sections, the NGMN V2X Task-Force team has outlined its feedback on the "Notice of Proposed Rule Making of US Department of Transportation / NHTSA". This feedback provides information on elements of NHTSA’s proposed rules that are supported by NGMN as well as improvements and changes to other elements of the proposed rules. As elaborated in the following sections, the NGMN V2X Task Force recommends USDOT be technology neutral in the rule making as cellular technologies beginning with 3GPP Release 14 could offer a technical and market-driven solution with a clear evolution path. We view this capability as a technology option that could be deployed well within the deployment horizon envisioned in NHTSA’s proposal and also be compatible with 5G as that deployment matures. This solution appears preferable by many measures including better technical performance, improved cost-efficiencies, and its flexibility to adapt to a variety of business models.
