ngc in 5g

Last updated on 

Here's a technical breakdown of NGC in 5G:

  1. Architecture Evolution:
    • Service-Based Architecture (SBA): One of the significant changes from the previous generation (4G LTE) is the move towards a Service-Based Architecture. In SBA, network functions are decomposed into modular services that can communicate using standard protocols like HTTP/2. This decoupling enables more flexible and efficient service deployments, scaling, and management.
  2. Network Functions in NGC:
    • AMF (Access and Mobility Management Function): Manages the mobility and connection establishment for users.
    • SMF (Session Management Function): Handles session management and user plane functionality. It is responsible for setting up and managing user data sessions.
    • UPF (User Plane Function): Manages the user plane packet routing and forwarding. It plays a crucial role in data packet handling, including the user data plane.
    • PCF (Policy Control Function): Responsible for policy enforcement, such as QoS (Quality of Service) management, flow-based charging, and network slicing.
    • UDM (Unified Data Management): Manages subscriber data, subscription data, and authentication information.
    • AUSF (Authentication Server Function): Handles authentication and security key management.
    • NEF (Network Exposure Function): Allows third-party applications to access the 5G network functions securely.
    • NRF (Network Repository Function): Maintains a registry of available services and capabilities within the 5G network.
  3. Network Slicing: One of the essential features of the NGC is the capability to support network slicing. Network slicing allows the creation of multiple virtual networks on top of a shared physical infrastructure. Each slice can be tailored to specific use cases, like eMBB, URLLC, or mMTC, with customized QoS, latency, and throughput requirements.
  4. Security Enhancements: The NGC introduces enhanced security features to protect against evolving threats and vulnerabilities. This includes improved authentication mechanisms, encryption, and secure communication protocols.
  5. Scalability and Flexibility: The NGC architecture is designed to be highly scalable and flexible. With the use of containerization and cloud-native technologies, network functions can be dynamically instantiated, scaled, and orchestrated based on demand.
  6. Service Orchestration and Automation: NGC incorporates automation and orchestration capabilities to streamline network operations, reduce manual interventions, and accelerate service deployments. This involves leveraging technologies like NFV (Network Functions Virtualization), SDN (Software-Defined Networking), and MANO (Management and Orchestration).
