- Location Management Function (LMF)
- Network Exposure Function (NEF)
- Network Slicing Selection Function (NSSF)
- Network Repository Function (NRF)
- Network Data Analytics Function (NWDAF)
- Policy Control Function (PCF)
- Session Management Function (SMF)
- Unified Data Management (UDM)
- Unified Data Repository (UDR)
- Unstructured Data Storage Function (UDSF)
- User Plane Function (UPF)
