5G Core (5GC)

5G Core

5G Core Network(5GC) holds a key role in realizing the full potential of 5G services. Without 5GC, fully-fledged NR services cannot be obtained. 5G NSA deployment leaning on traditional LTE network and EPC allows for a quick launch of 5G services, but also hinders the realization of 5G' s full potential.

Base on Service Based Architecture(SBA), in 5GC, a cloud native design is introduced to enable flexible scaling and upgrades.

Key Benefits:

• Supports VoNR/VoLTE/CSFB
  Allow operators to meet a variety of voice application scenarios
• Flexible Deployment
  Enable for centralized or distributed data centers
• Virtualized, Cloud-Native Dual-Mode 5G Core
  Support NSA/SA Networking
• Fully standards based, multivendor solution
  Supports end-to-end 5G Slicing
• 3G/4G/5G Converged Core
  Enable smooth handover among 3G, 4G and 5G
• Full Stack capabilites
  A complete core network portfolio, Simplify operators' network structure
• High scalable
  Enable to deploy on Cloud Platform such as AWS and Azure
• Enable more granular end-to-end management and control of traffic flows and applications
  

Comply to 3GPP R15/R16 Standards
A Service Based Architecture (SBA): AMF, SMF, PCF, UPF, UDM, AUSF, NSSF, NRF, NEF Full Functions

• AMF: Access and Mobility Management Function
• SMF: Session Management Function
• PCF: Policy Control Function
• UPF: User Plane Function
• UDM: Unified Data Management
• AUSF: Authentication Server Function

The IoT with NR

• VoNR

5GC NFV Architecture

• Cloud Native
• Docker

Separate the User Plane (UP) functions from the Control Plane (CP) functions, allowing independent scalability, evolution and flexible deployments e.g. centralized location or distributed (remote) location
