NF Heartbeat Interval

The SMF NF Heartbeat feature notifies the NRF that the SMF is operational. The default heartbeat interval is once in 10 seconds. With the heartbeat interval CLI command, you can configure the interval (in seconds) between the heartbeats. If NRF returns a different heartbeat time value as part of NF registration response or heartbeat response, then the same interval is used for subsequent heartbeats. As part of the heartbeat, NRF sends the HTTP PATCH Request to the resource URI representing the NF instance. The payload body of the PATCH Request contains a "replace" operation on the "nfStatus" attribute of the NF profile of the NF instance, and configures it to the "REGISTERED" value. This release does not support parameters, such as load and capacity.

Note

SMF uses the configured heartbeat. If the heartbeat is not configured, SMF uses the locally configured heartbeat.
