Feature Description
The SMF supports the deregistration of Network Function (NF) Repository Function (NRF), wherein the NF deregister service operation of the SMF removes the profile of a network function that is registered in the NRF.
The SMF starts the NF deregister service operation in the following scenarios:
-
When the Service Based Interface (SBI) endpoint is not configured and all the rest endpoints stop functioning.
-
When all the configured SBI endpoints VIP IP and N11 VIP IPs are offline.
Note | SMF can't perform NRF deregistration when all the REST endpoints abruptly stop functioning. Only the REST endpoints can perform registration or deregistration of NRF. |
