5G core (5GC)

Most CSPs use multiple cores to serve multiple access generations. There’s a better way that is more streamlined and efficient. CSPs deploy our core to simplify their networks with a single set of core software products, serving 5G SA, 5G NSA, 4G, 3G/2G and even fixed access (WiFi, DSL, Fiber, Fixed Wireless Access, etc.).

For the evolution of 5G NSA to 5G SA, explore our in-depth materials and make plans to deliver 5G’s full potential.

Security, data protection and privacy are increasingly important with 5G. The core provides a critical role in enabling mission-critical applications, Industry 4.0, IoT services, and consumer personalization. Trust is a vital attribute for these applications and services.

Nokia takes the security built into our products seriously. Our 5G Core is designed for privacy and security, with layered protection based on defense-in-depth design and zero-trust principles and tested against 5G-specific use cases. CSPs get full control to secure their 5G services, thanks to the pervasive and automated security management built into our design practices, 5G Core’s software, XDR security software, and NetGuard Cybersecurity Dome.

Previously, mobile core and telco cloud were automated for the sake of reducing costs, which was achieved by using a telco network element approach. This created islands of automation by relying on element management systems.

5G Core’s cloud-native architecture and techniques change the automation equation, enabling an automation framework based on exposing automation functions to each other via APIs and the creation of closed-loops with feedback. AI/ML techniques achieve further benefits, such as automated fixing of predicted faults.

Network Slicing allows CSPs to monetize services by creating discrete network slices that meet required levels of performance for individual customers and services. CSPs use our core network slicing to create and run separate networks on shared cloud infrastructure. These independent networks enable customized Service Level Agreements (SLAs) for connectivity, mobility, capacity, security, redundancy and performance.

The 5G Core is the anchor of network slices, because it controls a device’s subscription and slice selection. 5G and its cloud-native automation enables this – ensuring one network can be shared across many customers, allowing a CSP to deliver resources to meet the exacting needs of their customers, without impacting others.

Rising energy costs, climate change and sustainability initiatives have never been more important. CSPs urgently seek ways to improve their energy efficiency.

Our approach is to ensure efficient energy consumption at all levels of the 5G Core: hardware, cloud infrastructure, the core’s network functions, and its automation. Techniques include using the latest CPU chipsets, Kubernetes cluster-level power control, optimized architecture for reduced footprints, and power consumption monitoring and reporting.

Taken together with using AI/ML to continuously optimize the network, we enable you to improve your 5G Core’s energy efficiency.

Take advantage of 5G standalone core on public cloud & hybrid cloud infrastructure, automation, analytics, and innovation. Extending the 5G core to edge cloud and across multi-cloud helps enable fast time-to-market, investment agility, quicker operations, and new business opportunities with enterprises.
