Samsung 5G Core Cloud-Native Architecture: A Detailed Technical Overview

As 5G networks continue to develop, cloud-native architectures are becoming essential for the next generation of telecom systems. The diagram titled “Samsung 5G Core: Cloud Native Architecture” illustrates how Samsung organizes its 5G Core (5GC) with Cloud-Native Network Functions (CNFs), microservices, stateless functions, external shared databases (UDSF), and container management using Kubernetes and Docker.

This approach highlights how contemporary 5G core networks can achieve agility, scalability, observability, and high availability.

In this article, we’ll dive into the architecture and discuss the role of each component in creating an efficient, future-proof 5G core.

Understanding the Cloud-Native 5G Core (5GC)

The diagram emphasizes the shift from traditional monolithic Network Functions (NFs) to containerized microservice-based CNFs. This transformation is crucial because:

CNFs are quicker to deploy

Microservices can scale on their own

Stateless designs enhance resilience

Kubernetes automates orchestration

Overall, Samsung’s 5G Core architecture is made up of:

Stateless Network Functions (NFs)

Unified Data Storage Function (UDSF) for shared databases

Microservices specific to each NF

Common microservices

OAM (Operations, Administration & Maintenance) services

Container infrastructure managed by Kubernetes and Docker

Let’s break down each part.

Stateless NFs with a Unified Shared Database (UDSF)

At the top of the diagram, you can see the main 5G NFs linked to a shared database:

AMF (Access and Mobility Management Function)

SMF (Session Management Function)

NRF (Network Repository Function)

NSSF (Network Slice Selection Function)

These are labeled as stateless, meaning they don’t hold session or mobility data internally. Instead, they depend on a separate layer—the UDSF (Unified Data Storage Function).

Advantages of stateless NFs + UDSF are:

High availability: If one NF instance fails, another can seamlessly take over.

Efficient scaling: New instances don’t need to sync their state.

Lower latency: Sharing data cuts down on communication time between NFs.

Elasticity: NFs can scale out based on demand.

This approach is a fundamental aspect of cloud-native telecom design.

NF-Specific Microservices

Below the stateless NFs, the architecture breaks down each NF into several microservices, grouped by their functions. Some examples include:

Mobility

NF communication

Session management

Network Slice (NS) discovery

These microservices work with the NFs above (like AMF, SMF, NRF) to offer detailed scaling and modular features.

Why microservices are important in 5G:

Each module can scale on its own

Failures can be contained

Updates affect just the specific microservice involved

Teams can work on and deploy services at the same time

Microservices can be reused across different NFs

This fits well with modern DevOps and CI/CD methodologies.

Common Service Microservices

The design also incorporates Common Services, which deliver features shared among different NFs:

Interface services

Database management services

Event services

These functions help reduce redundancy across the 5G core and standardize operations.

Benefits of common services include:

Easier development

Consistency across NFs

Enhanced observability and tracing

Reduced operational complexity

Common services help facilitate internal service mesh designs, allowing for controlled communications among microservices.

OAM Service: Logging and Tracing

There’s a dedicated OAM (Operations, Administration & Maintenance) section that includes:

Logging services

Trace services

These microservices play a crucial role in:

Monitoring performance

Recovering from faults

Managing service performance

Meeting regulatory standards

Conducting security analysis

By containerizing OAM as microservices, Samsung enhances real-time visibility across its entire 5G core.
