Service-Based Architecture in 5G Case Study and Deployment Recommendations

The main target of this document is to investigate the following aspects, which were not covered in phase 1.

  • How to make services more decoupled to achieve independent Life Cycle Management (LCM) and flexible service deployment and management.
  • How to achieve high performance, including low delay, high concurrency, high reliability, and security
  • Investigate how to support roaming across different 5G core networks
  • Case study for generation of network slicing and edge computing by service
  • Case study and recommendations for a distribution strategy of network services


NGMN Technical Document 5G Small Cells at Home v1.0

5G Small Cells at Home

The first objective of this white paper is to explore the potential technologies that could help improve the performance of local connectivity at home.
In addition to this, the second objective is to look for solutions of radio resources management at home that would be controlled by the network. The current situation is that the local connectivity is selected by a connectivity manager embedded in the operating system of smartphones that may not have a complete view of what happens, for instance in terms of traffic on cellular networks.
The global objective for operators is then to keep home users connected wirelessly to their local – fixed access network based – connectivity (delivered e.g. by Wi-Fi, a “small cell at home”) with a “premium” quality of service instead of adding pressure on the Radio Access part of the mobile macro network. Challenges for mobile macro networks are for example a lack of (licensed) spectrum that can cover efficiently indoors from outdoor macro network (e.g. low bands spectrum), cost of the radio sites, incl. equipment.

5G Network and Service Management Including Orchestration

This document describes requirements for 5G Network and Service Management including Orchestration. The Document includes requirements covering all potential parts of future networks, i.e., fixed-, mobile-, cloud, virtualized technologies from a Network and Service Management including Orchestration perspective.

190903 RAN Convergence Paper 1

RAN Convergence Paper

NGMN and Wireless Broadband Alliance (WBA) have published the first results of their collaboration to drive the convergence of multi-technology RANs and core networks. The joint report identifies a number of emerging opportunities and use cases that the industry can benefit from through the convergence of 5G and Wi-Fi, driven by the ever-enhancing capabilities of licenced and unlicensed technologies. It also highlights the key challenges which must first be addressed in order to realise this convergence – including tighter integration of Wi-Fi access in 5G networks, network manageability and policy control, and the enablement of Wi-Fi-only devices.

190111 NGMN PreCommTrials Framework definition v2 small

Definition of the Testing Framework for the NGMN 5G Pre-Commercial Network Trials (Version 2)

This document (Version 2) 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.

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.
