Consensus, time and a focus on continuous improvement will be key elements for guiding the evolution of mobile networks towards 6G and beyond, building on the solid foundation of 5G. The Next Generation Mobile Networks Alliance (NGMN) revealed this today while publishing a proposed framework to guide the evolution of network architecture towards 6G. 

The “Network Architecture Evolution towards 6G” publication builds on NGMN’s “6G Position Statement – An Operator View”, published in 2023. It advises that the future 6G network architecture should address 5G gaps, support new scenarios and requirements, adapt to RAN changes, and embrace emerging technology trends. NGMN emphasises the importance of allocating sufficient time in the standardisation process to ensure industry-wide collaboration, enabling a smooth and continuous evolution of mobile networks towards 6G and beyond.  

“NGMN envisions the future network architecture as a service-based platform that evolves to efficiently meet the growing demands of users, applications and industries, while leveraging the ongoing advancements of 5G,” said Arash Ashouriha, Chairman of the NGMN Alliance Board and SVP Group Technology at Deutsche Telekom. “To ensure the next generation of mobile networks unleashes its full potential, it is important that clear architectural design and implementation principles are set at an early stage, promoting cooperation, minimising unnecessary complexity, and ensuring alignment with long-term objectives,” continued NGMN’s Chairman. 

The 6G network architecture design principles aim to address the limitations of 5G while ensuring support for new scenarios and requirements. MNOs participating in the study highlighted network complexity, challenges in integrating with legacy systems, and energy efficiency as key concerns with existing 5G networks that should not be repeated in 6G development. Autonomous network management and AI-native design were identified as key drivers for architectural change. 

Among the 13 principles established by NGMN, the evolving network architecture should enable innovation, support on-demand deployment of new features, and ensure backward compatibility with existing core connectivity services, reflecting a philosophy of continuous improvement and incorporate ‘quantum-safe’ infrastructure to enhance security, privacy, and resilience.  

MNOs involved in the development of these principles also suggested that a new 6G air interface should provide tangible improvements over 5G-Advanced in key areas, including increased spectrum efficiency, ISAC, and dense low-cost device connectivity. 

Following the publication of this framework, NGMN will lead further initiatives and publish recommendations and requirements on key areas of network architecture evolution. These include developing migration strategies, ensuring seamless coexistence with existing 5G networks, and exploring new capabilities that 6G must support. These efforts will guide the continuous evolution of network architecture towards a scalable, innovative, efficient, and sustainable framework, ensuring a seamless transition that empowers a truly connected and intelligent society. 

“The future of mobile networks lies in their ability to evolve continuously, much like software, to meet the changing needs of users and industries. By focusing more on gradual improvements and leveraging the strengths of 5G and beyond, we can ensure a sustainable flow of innovative features, keeping our customers delighted,” emphasised Laurent Leboucher, Member of the NGMN Alliance Board and Group CTO and Executive VP Networks at Orange.

The Next Generation Mobile Networks Alliance (NGMN) has today released four concise publications detailing essential operating models for disaggregated networks.  

These models aim to provide clear guidance to industry stakeholders and foster the adoption of disaggregated network architectures, which will provide mobile network operators (MNOs) with greater flexibility when managing and deploying of network infrastructure. The outlined operating models include:  

• Single Vendor Led 

• Systems Integrator (SI) Led 

• Operator Platform 

• Operator Platform commercially offered to others. 

“Disaggregation – the process of modularising, softwarising and running network functions on cloud native infrastructure – is revolutionising the telecommunications industry, said Arash Ashouriha, Chairman of the NGMN Alliance Board and SVP Group Technology at Deutsche Telekom. “This transition fundamentally changes how operators work internally and collaborate with the broader supplier ecosystem. With these publications, NGMN is taking the lead by offering practical, actionable guidance on the key operating models available today and helping operators navigate this shift effectively,” he added. 

“Software-based, cloud native network architectures are set to dominate the industry, empowering operators with greater flexibility and agility to manage networks, innovate new services, and address evolving customer needs,” said Bernard Bureau, Member of the NGMN Alliance Board and VP of Network and Architecture Strategy, at Chief Technology Office at TELUS. “At TELUS, we are proud to have worked with NGMN to provide deeper insights into the available options and the organisational transformations needed to fully realise the potential of disaggregated networking,” he added. 

The publications build on NGMN’s Cloud Native Manifesto (September 2023), which outlined seven key principles for accelerating the transition to cloud native networking. While the Alliance is prohibited under competition law from endorsing or recommending any specific operating model, these publications offer decision-makers a comprehensive understanding of the organisational changes required to implement each scenario. They also provide a balanced assessment of the advantages and challenges associated with each approach. The goal is to highlight the wide range of options available to the industry and the long-term considerations for adopting each model effectively. 

The publications, along with a brief overview document, are available for download here.

The publication was developed with input from across the industry, with NGMN’s membership comprising operators, vendors, and research institutions. This collaboration enables NGMN to offer strong guidance on key industry issues, driving progress on today’s most important topics, including NGMN’s Strategic Focus Topics: Mastering the Route to Disaggregation, Green Future Networks, and 6G. NGMN encourages all stakeholders across the value chain to join the Alliance in this endeavour. 

Düsseldorf, Germany, 03 December 2024 — The Next Generation Mobile Networks Alliance (NGMN) has released its latest publication, the “Radio Performance Assessment Framework,” providing the mobile communications industry with a comprehensive methodology to evaluate the value of new Radio Access Network (RAN) solutions. 

Building on the 2023 MNO Position Statement, which emphasised that any new RAN must deliver tangible additional benefits—such as enabling new user-driven use cases or improving operational efficiencies like energy consumption—this framework offers clear and actionable guidance for assessing RAN innovations. 

“This NGMN publication provides strong guidance towards ensuring that future RAN developments are in line with the expectations of operators on performance and efficiency,” said Luke Ibbetson, Member of the NGMN Alliance Board and Head of Group R&D, Vodafone. “Our Radio Performance Assessment Framework establishes a robust foundation for fair benchmarking and sets a new standard for delivering measurable value in the era beyond 5G Advanced.” 

Key Components of the Framework 

The Radio Performance Assessment Framework, primarily targeted for providing guidance to 3GPP, also provides general guidance to the broader ecosystem. Its goal is to enable fair benchmarking of vendor offerings and to ensure that new RAN solutions surpass the capabilities of 5G Advanced. 

The framework is built on three key pillars: 

1. Alignment with ITU-R IMT 2020 Metrics: 

• Radio performance metrics such as spectral efficiency, Total Radiated Sensitivity (TRS), Total Radiated Power (TRP), and energy consumption should align with ITU-R IMT 2020 specifications in 3GPP standards. 

2. Benchmarking Against 3GPP Release-18: 

• All new RAN solutions must demonstrate clear performance improvements when benchmarked against 3GPP Rel-18 specifications. 

3. Integration of 5G A Rollout Learnings: 

• The framework incorporates lessons learned from the deployment and operation of 5G Standalone (SA) networks, ensuring practical and informed assessment criteria. 

“This framework is a vital tool for fostering a collaborative and standards-based approach to advancing the RAN ecosystem,” said Konstantinos Chalkiotis, Member of the NGMN Alliance Board and VP Access Technologies & Spectrum, Deutsche Telekom. “It enables the industry to focus on creating real value for users while addressing critical challenges such as energy efficiency, other operational efficiencies and scalability.” 

The Radio Performance Assessment Framework is the latest in a series of NGMN initiatives to provide leadership and guidance on key industry topics. It reflects NGMN’s ongoing commitment to its Strategic Focus Topics, including Mastering the Route to Disaggregation, Green Future Networks, and 6G development.
