The aim of this work is to illustrate how 5G end-to-end deployment can meet vertical requirements and also highlight what are the main 5G URLLC technology enablers for use cases identified in the report. Some of these new use cases impose extremely low latency and high reliability requirements on 5G system from end-to-end perspective. This report also briefly describes 5G URLLC enablers along with reference architecture for specific use case and further evaluate how 5G URLLC can enable such use cases.
The Next Generation Mobile Networks (NGMN) Alliance has today published its ‘Continuous Delivery in Telecommunication Network Environments’ White Paper, setting out concepts to tackle the ‘air gap’ challenge.
The telecommunications industry is undergoing a fundamental transformation to become more software-centric and cloud-based, paving the way towards a more agile service environment and higher operational automation. On the journey to DevOps, through applying practices such as Continuous Integration (CI) and Continuous Delivery (CD), network operators at some point in time hit a challenge described in the White Paper as the ‘air gap’.
Caused by the fact that production networks are strictly segregated from test networks and development environment networks for security and operational reasons, this gap between CI automation in one network zone and deployment automations in other network zones hinders seamless CD automation. Solving the ‘air gap’ challenge is therefore an important step in the evolution towards true continuous deployment.
Using findings gained in recent projects, including DevOps practices from Deutsche Telekom (DT) and SK Telecom (SKT) including feedback from more than 25 NGMN Mobile Network Operators, the White Paper lays out the practical experience gained from automating the delivery chain for multiple applications, complemented by mapping the concept to a technology stack.
“This project has reinforced the importance of industry collaboration to expand and evolve telecommunications networks with a view to providing continuous deployment,” said Peter Meissner, CEO of NGMN. “Collaboration is key not just for NGMN but for the whole industry. To address the ‘air gap’ as well as other complex issues that operators face, stakeholders must combine skills, knowledge and resources to maintain advancements in the mobile ecosystem.”
“It is imperative that we move automation out of the advanced technology space and into production. As an industry, we must address the challenges that are hindering this progress,” said, Walter Goldenits, Chief Technology Officer, Telekom Deutschland, Deutsche Telekom. “The concepts explored in this White Paper are gained from practical experience and are intended now for alignment in industry activities around service orchestration and automation. I therefore encourage all interested parties to read and provide feedback to the White Paper.”
“Our ongoing work to identify new solutions that address the air gap challenge will prove critical as the industry undergoes a revolution towards DevOps practices,” said Kangwon Lee, VP & Head of Cloud Labs, ICT R&D Center, SK Telecom. “The industry is moving towards increased operational automation and a more agile service environment, but the change is not just about the technology – it is also about culture and methodologies. This NGMN White Paper is a key stage in the process.”
The White Paper presents the following key aspects:
- Outlines the target scenario for CD in telecommunication network environments
- Identifies key concepts for a model-based and reusable solution
- Examines various aspects of lifecycle management, putting CD into an even larger context
NGMN considers to initiate a project to further evolve the concept proposed in this White Paper jointly with industry stakeholders.
NGMN welcomes feedback from all interested parties on this White Paper and the evolution towards true continuous deployment.

Today, production networks are strictly separated from test networks and development environment networks for security and operational reasons. This gap between “Continuous Integration” automation in one network zone and deployment automations in other network zones hinders seamless “Continuous Delivery” automation.
This white paper focuses on solving the this challenge.
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 White Paper and subsequent deliverables published by NGMN.
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.
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
