With the theme of “Enhancing Ecosystem towards ICDT Convergence for 5G and Beyond”, the speakers shared their latest and comprehensive progress, experience, challenges, solutions, business model for vertical industry, as well as vision and roadmap for 5G and beyond. At the closing of the forum, the speakers released a Joint Statement on 5G promotion together, demonstrating their dedication of collaboration to lead the industry towards a Green, Soft, Open and Smart 5G era. The detailed joint statements are:

  • To collaborate in building an open 5G ecosystem, with open architecture and interfaces, open source software and open reference design hardware to facilitate the E2E cost effectiveness and accelerate the maturity of both SA and NSA with global roaming to fulfill the true potential of 5G.
  • To accelerate embedding network intelligence, by leveraging big data and ML/AI, to enhance the network operation, management and real-time performance.
  • To construct a comprehensive Green framework, from material and device, equipment function and HW platform, to network architecture and multi-network operation technologies to guarantee the industry sustainability.
  • To further exploit cloud, virtualization and container technologies to improve E2E network Softwarization and realize Network as a Service (NaaS).
  • To share experience and the best practice of business model and E2E solutions for of vertical industries for a commercially successful 5G era.

“I am very happy to see such heavy-weight event held in China, with the representation from so many industry-leading companies,” Said Dr. Zhengmao Li, the EVP and CTO of China Mobile, and the chair of the CTO Forum, “5G is deemed to transform the society that humanity thrive in. As the world-largest operator, it is our unshakable mandate to build a most cost effective and enabling 5G network infrastructure and services. China Mobile is fully committed to work with our partners and all members of our ecosystem for a sustainable and prosperous future together.”

“With 5G we are building society infrastructures. Building the right architecture: multi domain, multi vendor and regionalized CORE SA, with a clear proposal in Edge Computing and Open Source implementation, are keys for guarantee the availability.” Said Mr. Enrique, the GCTIO of Telefonica, and the co-chair of the CTO Forum, “Orchestration and Integration, combined with AI tools will be key for the maturity and velocity, necessary for the new industry and society services demands.”

Randeep Sekhon, Chief Technology Officer, Bharti Airtel said “Indian market is continues to see huge growth in mobile broadband adoption and volume. We are continuously expanding our 4G footprint, digitizing our operations and making future ready networks for 5G to provide superior data experience to our customers. 5G, IOT & AI/ML would help in realizing government’s vision of Digital India. We encourage an open ecosystem with collaboration between the operators and application players to build smart future ready networks and customer centric services.”

“5G has been growing very rapidly in Korea since the commercial launch last April. Global 5G Operator Forum is a great opportunity to share KT’s experiences of 5G network deployment and operation and to understand other global operators’ plans for 5G.” Said Mr. Lee, the SVP of Korea Telecom, “Moving forward, I believe that open, intelligent, software-based network solutions will be more and more important to develop business models and technologies for 5G B2B market as well as vertical industries, and KT hopes to collaborate closely with global operators for such solutions with this Joint Statement.”

Mark Chong, Group Chief Technology Officer, Singtel said, “With the arrival of 5G, enterprises are poised to take advantage of the enhanced capabilities for innovation to transform industries and societies. We are pleased to participate in the Global 5G Operator Forum to accelerate the advancement of the technology and 5G ecosystem.”

5G E2E Technology to Support Verticals URLLC Requirements

//in , //by

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.

5G End-to-End Architecture Framework v3.0.8

//in , //by

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.

190903 RAN Convergence Paper

Joint NGMN/WBA RAN Convergence Paper

//in , //by
In order to examine the best future solutions for convergence of Wi-Fi and 5G, this paper examines the current Wi-Fi interworking solutions available for 4G systems using either trusted or untrusted Wi-Fi access, through either Core Network based or RAN level integration. It also reviews the 3GPP 5G system approach to Wi-Fi access, which includes integration of untrusted Wi-Fi access in Release 15 and the new opportunities in Release 16 for trusted Wi-Fi access as well as wireline and cable modem access such as from a residential gateway. Release 16 specified Access Traffic Steering, Switching and Splitting (ATSSS) functionality is analyzed which enables data session over one or more concurrent accesses.

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

5G Small Cells at Home

//in , //by

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.

RAN Convergence Paper

//in , //by

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.
