This document delineates the requirements in terms of entities and functions that characterise the capabilities of an E2E (end-to-end) framework. Architectural perspectives and considerations associated with the service categories – eMBB, mIoT, URLLC – envisioned for 5G (Fifth Generation) underscore the delineation of the E2E framework requirements. These requirements are intended as guidance in the development of interoperable and market enabling specifications for a continuing advancement of the 5G ecosystem of heterogenous access, virtualization, autonomic capabilities, forward-looking service enablers, and emerging usage scenarios.
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.
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
