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.
NGMN has updated its report “5G Security – Package 3: Mobile Edge Computing / Low Latency / Consistent User Experience”. The original version was published in 2016. The most significant updates, in sections 1.10.2 and 2.2.2, have been made in response to constructive feedback received from ETSI TC LI, and concern the interplay of law enforcement (lawful interception, data retention etc) with edge computing and low latency solutions. We also recognise the new terminology “Multi-Access Edge Computing”.
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.
Architectural Proposal for the Handling of Network Operations Data with Specific Focus on Virtualized Networks
The solution architecture presented in this document proposes simplified principles for handling network operations data that can be applied on a large scale. In this white paper, the authors focus on obtaining access to network operations data for the purpose of network monitoring and other applications.
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.
This White Paper builds on the original NGMN 5G White Paper of 2015 and the NGMN Spectrum White Paper of 2017. It addresses in more detail the spectrum and regulatory issues in relation to implementation of 5G networks.
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.
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.
This document is the technical report for the "Test of Technology Building Blocks" work stream of the NGMN 5G Trial and Testing Initiative. It provides the full description for each of the technology building blocks that have been identified as carrying higher priority by NGMN community, and the corresponding test results.
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.
