Table 4-31 Default Notification Subscriptions

Attribute name	Description
Callback Uri	This attribute contains a default notification endpoint to be used by a NF service producer towards an NF service consumer that has not explicitly registered a callback URI with the NF service producer, for example, as a result of an implicit subscription.
Notification Type	Type of notification for which the corresponding callback URI is provided.
Versions	API versions, for example, v1, are supported for the default notification type.
N1 Message Class	If the notification type is N1_MESSAGES, this IE must be present to identify the class of N1 messages to be notified.
N2 Information Class	If the notification type is N2_INFORMATION, this IE must be present to identify the class of N2 information to be notified.
Binding	When present, this IE contains the value of the binding indication for the default subscription notification, which is the value part of the 3gpp-Sbi-Binding header. See the note for details.

Note:

When delivering a notification for a default subscription to a specific NF consumer but the latter is not reachable, a NF service producer uses the binding indication for default subscription to reselect an alternative NF service consumer instance. For example, an AMF notifies corresponding uplink LPP or NRPPa messages through a default subscription to the LMF instance that previously sent downlink LPP or NRPPa messages during a location procedure. If the original LMF instance is not reachable, the AMF selects an alternative LMF instance using the binding indication and delivers the notification to the selected LMF instance.

By default, SCP considers 24 as the priority for the ingress message request if the message does not have the "3gpp-Sbi-Message-Priority" header. If the priority of the ingress message request is less than the value of SBI Message Priority Discard From, then the message is considered as high priority message.
- SCP discards all the 5G SBI messages whose "3gpp-Sbi-Message-Priority" header value is equal to or greater than this configuration.

If the user has changed the 'Admin State' from ENABLED to DISABLED, this state means the feature is successfully disabled. IN_PROGRESS: This indicates the enabling or disabling of the feature is currently is in progress when the 'Admin State' is set to ENABLED or DISABLED. For example, in the nrf_bootstrap_info feature, when the 'Admin State' is ENABLED, the migration from static to DNS SRV based NRF topology is in progress. In the nrf_bootstrap_info feature, when the 'Admin State' is DISABLED, the migration from a DNS SRV based NRF topology to static NRF topology is in progress. FAILED_RETRY: This indicates that the process of enabling or disabling the feature (as indicated by the 'Admin State') has encountered failure and is undergoing retries. For example, in the nrf_bootstrap_info feature, this state means either of the migration tasks has failed and going through retries. ENABLED: This indicates the feature is successfully enabled. For example, in the nrf_bootstrap_info feature, this state means the migration from static to a DNS SRV based NRF topology is successful.
