NGMN Alliance seeks the rapid development of Option 4 as complement to 5G Standalone

//in //by

Frankfurt, Germany: Today, the Next Generation Mobile Networks (NGMN) Alliance releases its latest Operator Position Statement paper urging the development finalization of 5G architecture “Option 4” to support the full realisation of 5G. Its Option 4 recommendation will help many networks to bring new 5G-based services quickly and efficiently to market whilst also providing a future-proof evolution that maintains competitive user data rates for 5G users.

A migration to 5G Standalone is an important evolutionary step for 5G with the introduction of a new 5G core network and the transfer of the master radio interface technology from LTE to New Radio (NR) technology. To ensure the most cost and spectrum efficient use of the network which maximises the full 5G advantages, advanced 5G users should be able to connect in parallel via both NR and existing LTE technology. Otherwise new 5G Standalone users will sometimes receive lower data rates than existing Non-Standalone 5G and LTE-only users.

“Development completion of Option 4 is urgently needed to enable all operators to invest in a new 5G core network without compromising user data rate performance,” said Arash Ashouriha, Chairman of the NGMN Alliance. “Advanced 5G users using 5G Standalone should be able to access LTE on top of NR for a seamless service experience”.

NGMN concludes that Option 4 supporting a 5G core and dual connectivity with NR acting as a master is required so that baseline 5G NR radio performance can be enhanced through the use of LTE on top. 5G Standalone users can then access both NR and LTE spectrum in the lower frequency bands supporting wider coverage when it is beneficial to do so.

Raimund Walsdorf, Technology Architecture & Innovation Access & Home Networks, Deutsche Telekom and NGMN project lead said: “Option 4 development will support many network operators planning an initial 5G Standalone service launch today or a more widespread launch in the future. This option benefits operators to more efficiently migrate spectrum from LTE to NR, while also relaxing the pressure on operators to refarm from LTE to NR as long as spectrum remains dedicated to LTE”.

Anita Döhler, CEO, NGMN Alliance added: “NGMN is committed to support an efficient introduction of 5G Standalone (SA) networks to help the industry to deliver on the performance promise of 5G to end-users. Availability of Option 4 in addition to other options will help to better meet end-user demands in years to come.”

The white paper is a result of an ongoing NGMN project which aims to conduct a trial of Option 4 in 2021. This will encourage Option 4 development within the 5G ecosystem with the aim that 5G Standalone can be introduced in all networks in a timely manner. The support of network and terminal suppliers is sought to progress the trial.

5G Smart Devices Supporting Network Slicing

//in //by

The 5G network system can provide on-demand network slices to satisfy different service requirements. However, how to create traffic connection for network slicing in 5G devices internally is still a technical gap. The design of Network Slicing function in 5G devices has to rely on 5G devices operation system as well as the traffic descriptors of the service between the upper layer and the modem, which results in that the current 5G devices does not support the use of network slicing. Therefore, the fundamental purpose of this document is to provide the reference design of network slicing solution in the 5G devices.

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.

Continuous Delivery in Telecommunication Network Environments

//in //by

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.
