Feature Description
In the 5G service-based architecture, the Network Repository Function (NRF) maintains an updated repository of all 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.
UPF supports only the NRF Management service that enables NF instances in the serving PLMN to register, update, or deregister their profiles in the NRF.
For more information, refer to the NRF Support chapter.
