The framework, outlined in NGMN’s latest publication Framework for Network Simplification – An Operator View, is designed as a practical reference for operators at very different stages of 5G deployment.

It applies both to advanced MNOs running cloud-native 5G cores with extensive radio access network (RAN) rollouts, and to early-stage operators still largely reliant on LTE and preparing to deploy 5G non-standalone (NSA).

NGMN argues that simplification is no longer optional as networks grow more complex. “As mobile networks evolve, MNOs face both growing complexity and new opportunities. To minimise operational costs, enhance efficiency, and unlock new services over 5G, network simplification must be a core pillar of network evolution strategies across both architecture and operations,” said Laurent Leboucher, chairman of the NGMN Alliance Board and Orange Group CTO and EVP of networks.

He added: “NGMN’s latest guidance provides operators with a clear framework to understand where and how simplification can be achieved, and to assess its targeted benefits against domain-specific goals and constraints, enabling informed deployment choices aligned with individual business and regulatory environments.”

The publication proposes a three-step approach. First, it identifies key technology trends that can drive simplification, including cloud-native architectures, agentic and generative AI, the exposure of federated network services, and advances in optical fibre technology. Alongside these, NGMN highlights agile ways of working as a critical non-technical enabler for delivering new services more quickly.

The second step focuses on the challenges operators face when adopting these enablers, across radio, core and transport domains. The final step encourages MNOs to prioritise technologies and network domains based on their specific level of 5G maturity, with the framework defining three common operator archetypes to support this process.

NGMN says the work will feed directly into its ongoing cloud native, network automation and 6G projects.

“As mobile networks become ever more complex, MNOs need to constantly strive to introduce simplification in how they create, deploy, expose and manage their differentiated service offerings for their customers,” said Anita Döhler, CEO, NGMN Alliance.

“By bringing together the insights from leading global operators, we are providing practical guidance to help MNOs navigate technological and organisational changes on the road to simplified, future-ready networks.”
