NGMN Alliance Launches Initiative to Advance Cloud, Automation & Edge Computing

Frankfurt, Germany – The Board of the Next Generation Mobile Networks (NGMN) Alliance launches new key activities to support the adoption of a cloud native infrastructure for telecommunication service providers. The initiative will address hybrid cloud architecture (e.g. edge computing) challenges and will lead to a paradigm change in the network vision of the industry.

The project has been highlighted as a crucial development area to further optimise and guide the telecoms industry towards the successful deployment of 5G beyond 2020.

TIM senior manager, project sponsor and member of the NGMN Alliance Board Andrea Calvi said: “We’re delighted to be leading the way with 5G projects that will address and define the high level target architecture for telco networks based on cloud native infrastructure, open interfaces and open source adoption. This will open vendor ecosystems, reduce TCO and gain flexibility.”

“NGMN is proud to be leading the efforts to address and define the target architecture for the most relevant use cases for E2E automation and orchestration, made possible by this initiative.” said Dr. Peter Meissner, CEO of the NGMN Alliance. “The qualitative effects of cloud native will support telco service providers with value creation and sustainability.”
The work will address requirements from operators who are keen to deliver efficient, high-quality and reliable 5G networks to the market. Activities include cloud native infrastructure, hardware dis-aggregation, open interfaces, open platforms, edge computing, and automation.

NGMN recognises that a number of industry organisations are currently working on different aspects of the topics described above. This NGMN initiative aims to facilitate a close alignment leading to the integration of results to form a common architectural view.

NGMN Alliance and ESOA Members Collaborate to Extend Rural Connectivity with Non-Terrestrial Networks

Frankfurt, Germany – The Next Generation Mobile Networks (NGMN) Alliance in collaboration with members of the EMEA Satellite Operators Association (ESOA) have progressed the development of Non-Terrestrial Networks (NTNs) as 3GPP enhances 5G to support non-terrestrial access in their Release 17 work programme.

Providing a convincing case for the implementation of NTN technology, the NGMN Alliance worked with key ESOA members to successfully demonstrate to 3GPP that space-based networks provide an effective alternative for network connection beyond traditional deployment methods, especially in rural areas. “It was a great achievement to make an impact on 3GPP’s decision to include NTN in the Release 17 work programme through the NGMN Alliance NTN positon paper, which demonstrates technological integration between terrestrial and non-terrestrial networks to significantly progress the extension of network coverage” said Sebastien Jeux (Orange), lead of NGMN project “Extreme Long Range Communication for Deep Rural Coverage”.

The paper highlights the requirement for mobile network operators (MNOs) to integrate space-based systems into their networks.

“We are proud to demonstrate the potential of the integration of terrestrial and NTNs to provide internet and mobile broadband services to users in harder to reach areas such as coastlines, forests, deserts and mountains.“ said Dr. Peter Meissner, CEO of the NGMN Alliance. “By 2025, we envision the full deployment of NTNs to meet the challenges of mobile network operators and vertical industries in terms of reachability, availability and resilience which will make a significant difference to the extension of 5G connectivity.” 

Integrating space-based systems with existing terrestrial networks enables mobile network operators to overcome the challenge of signal quality and roaming capabilities in underserved areas.

In the 5G world, terrestrial and non-terrestrial networks will further complement each other including utilizing integrated 5G direct satellite access to conventional smartphones in order to deliver superior coverage to users.

Several use cases were also identified for new satellite-based services in the absence of conventional cellular coverage. These go beyond rural broadband and vehicular connectivity to include geostationary orbit satellite (GEO) fixed Internet of Things (IoT) direct connectivity, which will aid farming, sensing, asset tracking and oil and gas vertical markets. Ultimately, the development will facilitate the movement towards advanced public safety and smart cities.

The paper further assesses reliability and efficiency with regards to the feasibility of service transmission between user equipment (Class 3 UE, Very Small Aperture Terminal (VSAT) UE and IoT devices) and NTN platforms such as satellites – both GEO and non-geostationary (NGSO) – and high-altitude platforms (HAPs), concluding that NTNs can provide direct mobile broadband access.

NGMN will continue deeper NTN analysis based on the requirements of mobile network operators expressed in this White Paper, jointly with all industry stakeholders.

Precom NW Trials Conclusions

Pre-Commercial Networks Trials Major Conclusions

Given the freeze of 3GPP Release 15 5G standards and the onset of some initial 5G commercial deployments in countries such as South Korea, many operators accelerated their 5G trials in 2019.

As a part of NGMN 5G Trial and Testing Initiative (TTI) project, some major NGMN operators, shared their initial 5G trial results.

Pre-commercial network trials phase of 5G TTI aims to consolidate the results from different operators and reach some major conclusions.

Overall, this consolidation effort, which gathers Trial reports mostly performed using a common methodology, permits to draw some very promising conclusion on the performances of early 5G implementations. Additionaly, it brings as well some observations that could lead to future improvements.

TIM’s 5G overcame the 2 Gbps speed, a new European record achieved on the mmWave live network

TIM confirms its leadership in 5G innovation and in the development of next-generation networks and services by successfully completing the first connection in Europe able to permanently overcome the 2 Gbps speed on a 5G live commercial network with 26 Gigahertz (GHz) millimeter-wave (mmWave) frequencies acquired through MiSE’s 5G bid.

TIM has achieved this key record together with Ericsson and Qualcomm, two NGMN partners, and this represents an additional milestone regarding millimeter-wave to those already achieved in Turin in 2017 through the first 5G connection in Italy and in Rome in 2018, with the first 5G videocall in Europe.

This result marks a significant milestone toward 5G evolution, kicking-off the use of 200 MegaHertz (MHz), acquired through MiSE’s bid on 26 GHz spectrum, in addition to further 200 MHz available thanks to the bid’s Club Use[1], for a total amount of 400 MHz. The performances achieved will improve significantly during 2020, as the network will be able to use up to 800 MHz and afterwards up to 1.000 MHz.

Being able to achieve Gbps speeds and provide with high network capacity thanks to the wide bandwidth available, 26 GHz mmWave frequencies fit the further development of 5G Fixed Wireless Access (FWA) services both in the areas not yet covered by fixed ultrabroadband and the creation of “dedicated” 5G indoor coverage. Furthermore these features enable new Industry 4.0 scenarios based on services with exceptional high speed, extremely low latency and the highest security and reliability levels.

TIM achieved the significant milestone grounded on a standard 3GPP Non-Stand Alone (NSA) solution able to let devices and network components from different providers interacting and to aggregate TIM’s 4G and 5G network, already implemented in 3.7 GHz spectrum.

Michele Gamberini, TIM’s Chief Technology and Information Officer commented: “TIM has been pioneer in the millimeter-wave spectrum innovation and with this new European 5G record the company confirms its technological leadership, thanks to its strive toward innovation and a cutting-edge network infrastructure, able to enable the entire country’s digital transformation. This milestone paves the way to the development of new 5G solutions to grant fixed ultrabroadband to families, companies and public authorities not yet covered. This also includes coverage dedicated to the development of robotics and automation digital services in the smart manufacturing area. All of our customers will therefore be able to take advantage of a wide range of integrated solutions that will allow them to fully enter the Digital Society.

Emanuele Iannetti, Country Manager at Ericsson Italy, says “5G will be the main innovation platform of the next decade and it will allow Italy to be increasingly competitive and attractive in the global scenario. We are extremely pleased that TIM has chosen Ericsson’s 5G technology to achieve this important milestone, placing our country at the forefront of the commercial implementation of the fifth generation of mobile networks. Ericsson thus confirms its technological leadership and its readiness to anticipate any market demands.

“Qualcomm Technologies congratulates TIM on this significant milestone which again demonstrates the potential of 5G mmWave technology and shows how operators are able to use a wide range of spectrum bands to deploy 5G. 2020 will see a significant expansion in 5G coverage and the use of mmWave bands will play a clear role in the build-out”, said Enrico Salvatori, president, Qualcomm EMEA.

[1] 26GHz Club Use means the possibility – exclusive for 5G millimetre-wave spectrum assignees – to use the full 1 GHz band if not used by other assignees

Small Cell Cost Sharing

Ideas for Small Cell Cost Sharing – Short Report

There is a long held vision of very high capacity networks using small cells in areas of high demand. With the expected availability of large quantities of mmWave spectrum for 5G, this opportunity in principle becomes even greater. But the economics of small cell deployment have proved very challenging in practice – and this challenge will only increase at mmWave frequencies, where coverage of an individual cell is typically even smaller. Unless the industry can find ways to reduce the per cell building, operation and maintenance costs, the opportunity to build out small cell networks using mmWave spectrum will be severely constrained.

NGMN carried out a study to identify and assess different approaches to improving the economics of small cells through some form of cost sharing between operators (with 5G small cells typically anchored to a 5G or LTE coverage layer). This short public report presents the most important and interesting ideas arising from that study. A fuller report from the NGMN study is also available
