In recent months, a noteworthy trend has emerged in the realm of telecommunication research: the increasing demand for a mobile network devoid of management functionality. Essentially, stakeholders are seeking a network that serves merely as a component of a larger ecosystem. To many entrenched in the telco domain, this concept may seem perplexing, if not outright absurd. After all, we’ve long embraced the notion that private networks lack charging functionality, rely on direct roaming arrangements between networks, and often adopt a trial-and-error approach to network planning. Now, we’re confronted with the prospect of networks devoid of subscriber management systems, alarm displays, and traffic monitoring tools.

As NEMO progresses into the latter stages of its project lifecycle, concrete inquiries emerge regarding the integration of 5G technology within this multifaceted platform. At the forefront of this endeavor lies the pivotal question: How can we seamlessly incorporate 5G access into the NEMO network controller? Upon initial examination, it becomes apparent that numerous functions are redundantly performed across both the 5G network and the NEMO network controller. In essence, NEMO serves as the overarching framework that delineates the future trajectory of network integration endeavors.

Enter Cumucore’s 5G Core (NC), renowned for its exceptional flexibility and adaptability. Leveraging a spectrum of integration options, ranging from RESTful APIs to more traditional telco Network Exposure Function (NEF) approaches, Cumucore’s solution offers unparalleled versatility. Indeed, the boundaries of flexibility can be pushed to extremes, enabling the relocation of all network management functions external to the core network infrastructure. The realm of possibilities is virtually limitless, presenting a tantalizing prospect for future architectural discussions surrounding 6G networks.

Central to these discussions is the fundamental question of which functions necessitate exposure within private networks for external control. While the landscape may evolve, one certainty remains: private networks will inherently require capabilities distinct from those of their public counterparts. As we navigate the intricacies of network architecture, it becomes increasingly evident that the delineation between public and private networks extends far beyond mere access. Rather, it encompasses a spectrum of functionalities, each tailored to address the unique demands of disparate environments.

At the heart of this paradigm shift lies the recognition that the conventional delineation between access and core functionalities is no longer sacrosanct. Instead, we must embrace a holistic approach to network design, one that transcends traditional boundaries and fosters seamless integration across disparate systems. Cumucore’s 5G NC serves as a beacon of innovation in this evolving landscape, offering a blueprint for the convergence of access and core functionalities within private network environments.

As we chart the course for the future of telecommunications, one thing is abundantly clear: the era of standalone access networks is rapidly fading into obsolescence. In its place emerges a new paradigm, one characterized by symbiotic relationships between diverse network components and a relentless pursuit of interoperability. Through strategic partnerships and technological innovation, we stand poised to usher in a new era of connectivity—one defined not by isolated networks, but by the seamless integration of disparate systems in pursuit of a common goal: unparalleled efficiency and connectivity in an ever-evolving digital landscape.
