Feature Description

In the 5G service-based architecture, the Network Repository Function (NRF) maintains an updated repository of all the 5G Network Functions (NFs) available in the operator's network. NRF also contains the details of the services provided by the 5G NFs, and allows the 5G NFs to instantiate, scale, and terminate without or minimal manual intervention.

NRF interacts with all NFs in the 5G core network, and provides the following services:

  • Management Services

  • Discovery Services

  • OAuth2 Authorization

  • Bootstrapping

The UPF supports only NRF Management Services.
