What are the key deployment options for the 5G Core network?

Last updated on 

The deployment options for the 5G Core network involve several architectural configurations that allow network operators to tailor their infrastructure to specific requirements and use cases. The 5G Core (5GC) network is designed to provide enhanced capabilities compared to its predecessors (4G/LTE) and is built around key concepts such as network slicing, cloud-native architecture, and service-based architecture. Below are the key deployment options for the 5G Core network:

  1. Centralized or Distributed Deployment:
    • Centralized Deployment: In this model, all the components of the 5G Core are deployed in a centralized data center. This data center can be cloud-based or located in a central physical facility. It simplifies management and maintenance but may introduce latency for certain services due to the centralized nature.
    • Distributed Deployment: In a distributed deployment, the 5G Core functions are distributed across multiple locations, including central and edge data centers. This helps reduce latency and improve the overall performance of the network, especially for services that require low-latency communication.
  2. Cloud-Native Deployment:
    • The 5G Core network is designed to be cloud-native, leveraging containerization and microservices architecture. Cloud-native deployments enhance scalability, flexibility, and efficiency by allowing network functions to be deployed and scaled independently. This supports the dynamic nature of 5G services and facilitates the implementation of network slicing.
  3. Network Slicing:
    • Network slicing is a key feature of 5G that enables the creation of multiple virtual networks (slices) on a shared physical infrastructure. Each network slice is tailored to specific requirements, such as latency, bandwidth, and security, to meet the diverse needs of different use cases. Network operators can deploy slices for enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), and ultra-reliable low-latency communication (URLLC).
  4. Service-Based Architecture (SBA):
    • The 5G Core adopts a service-based architecture where network functions communicate with each other through standardized interfaces using HTTP/2-based protocols. This modular and loosely coupled architecture allows for easier scaling, upgrading, and replacement of specific network functions. SBA contributes to the flexibility and agility of the 5G Core.
  5. Multi-Access Edge Computing (MEC):
    • MEC involves deploying computing resources closer to the edge of the network, allowing for low-latency processing of data. This is particularly beneficial for applications and services that require real-time interactions, such as augmented reality, virtual reality, and critical IoT applications. MEC can be integrated into 5G Core deployments to enhance edge computing capabilities.
  6. Public Cloud, Private Cloud, and Hybrid Cloud:
    • 5G Core components can be deployed on public cloud infrastructure, private cloud infrastructure, or a combination of both in a hybrid cloud model. Public cloud deployments offer scalability and cost-efficiency, while private cloud deployments provide greater control and security. Hybrid cloud solutions combine the benefits of both public and private clouds.
  7. Federation and Roaming:
    • The 5G Core network supports federation and roaming agreements between different network operators. This enables seamless connectivity and service continuity for users as they move between different service providers' networks.
