Request Body Parameters

Table 9-17 Type NnwdafEventsSubscription

Parameter Data Type Presence Description
eventSubscriptions array(EventSubscription) M Subscribed events. The event parameter within event subscriptions is "NETWORK PERFORMANCE"
evtReq ReportingInformation O Represents the reporting requirements of the event subscription. If this parameter is not given then the default values for ReportingInformation is used. The notification method "notifMethod" within ReportingInformation takes precedence over notificationMethod within EventSubscription.
notificationURI URI C URI to which the NWDAF sends the reports.
eventNotifications array(EventNotification) C

Notifications about Individual Events.

Present only if the immediate reporting indication in the "immRep" attribute within the "evtReq" attribute is set to true in the event subscription, and the reports are available.

Present in the response to NWDAF subscription if "immRep" is true and the reports are the available.
failEventReports array(FailureEventInfo) O Supplied by the NWDAF. When this parameter is available,it contains the event(s) for which the subscription is not successful including the failure reason(s). This parameter is populated and returned in response to the error case.
consNfInfo ConsumerNfInformation O Represents the analytics consumer NF information.
notifCorrId String M Notification correlation ID. It is generated after successful subscription and is returned back in the response.
supportedFeatures SupportedFeatures C

This parameter is supplied by NF service consumer in the POST request for creation of an NWDAF Event Subscriptions resource, and supplied by the NWDAF in the reply of corresponding request.

Value is "080" for Network Performance ID.

Table 9-18 Type EventSubscription

Parameter Data Type Presence Description
event NwdafEvent M

Event that is subscribed. The value for network performance ID is "NETWORK PERFORMANCE"
extraReportReq EventReportingRequirement O The extra event reporting requirement information.
loadLevelThreshold Integer C Indicates that the NWDAF shall report the corresponding network slice load level to the NF service consumer where the load level of the network slice identified by snssais is reached.
matchingDir MatchingDirection O A matching direction may be provided alongside a threshold. If omitted, the default value is CROSSED.
networkArea NetworkAreaInfo C

Identification of network area to which the subscription applies.

The absence of this parameter means the subscription is applicable to all the network areas.
notificationMethod NotificationMethod O Indicates the notification method.
repetitionPeriod DurationSec C Shall be supplied for notification method "PERIODIC" by the "notificationMethod" attribute.
tgtUe TargetUeInformation O Identifies target UE information.
nwPerfRequs array(NetworkPerfRequirement)  

Represents the network performance requirements. This attribute shall be included when subscribed event is "NETWORK_PERFORMANCE".

It may only be present if "appIds" attribute is provided.

Table 9-19 Type NnwdafEventsSubscriptionNotification

Parameter Data Type Presence Description
eventNotifications array (EventNotification) C Notifications about individual events.
subscriptionId String M String identifying a subscription to the Nnwdaf_EventsSubscription service.

Table 9-20 Type EventNotification

Parameter Data Type Presence Description
event NwdafEvent M Subscribed events. The event parameter within event Subscriptions has to be "NETWORK PERFORMANCE"
start DateTime O It defines the start time from when the analytics information becomes valid.
expiry DateTime O It defines the expiration time after which the analytics information will become invalid.
timeStampGen DateTime C It defines the timestamp of analytics generation.
duration Duration C It defines the time period for which the threshold was in the target state.
nwPerfs array(NetworkPerfInfo) C The network performance information.

Table 9-21 Supported Response Codes

Code Description
201 The subscription is created successfully.
400

Bad Request.

The request is incorrect and subscription is not created.
500 Indicates a internal server processing error.

Examples

The following example shows how an NF creates a subscription for Network Performance analytics by submitting a POST request on the REST resource using cURL.

QoS Sustainability Analytics Rest API Parameters

Note:

The data types supported by OCNWDAF comply with the 3GPP specifications. For more information about the 3GPP data types, see 3GPP Technical Specification 29.520, Release 17, Network Data Analytics Services.

Request Parameters

Listed below are the QoS sustainability analytics request parameters:

Table 9-33 Request Parameters

Parameter Data Type Presence Description
eventSubscriptions Table 9-34 M Specifies the subscribed event. The event parameter within the subscription is set to "QOS SUSTAINABILITY".
evtReq ReportingInformation O Represents the reporting requirements of the event subscription. If this parameter is not provided, the default values for ReportingInformation is used. The notification method "notifMethod" within ReportingInformation takes precedence over the notificationMethod within EventSubscription.
notificationURI Uri C The URI to which OCNWDAF sends the reports
eventNotifications array C

Notifications about individual events

This parameter is present if the immediate reporting indication in the "immRep" attribute within the "evtReq" attribute is set to true in the event subscription and the reports are available.

This parameter is provided in response to the OCNWDAF subscription if immediatereport is true and the reports are available.

failEventReports array O This parameter is provided by the OCNWDAF. When this parameter is available, it contains the event(s) for which the subscription is not successful, it also includes the failure reason(s). This parameter is populated and returned in the response for the error case.
consNfInfo ConsumerNfInformation O Represents the analytics consumer NF information
notifCorrId String M Notification correlation identifier. It is generated after a successful subscription and is returned in the response.
supportedFeatures SupportedFeatures C This parameter is provided by the NF service consumer in the POST request for creating an OCNWDAF Event Subscription resource, and it is also provided in response to the corresponding request.

Table 9-34 EventSubscription

Parameter Data Type Presence Description
anySlice AnySlice M Represents the any slice. Default is FALSE.
appIds array C Note: This parameter is not applicable for QoS sustainability analytics.
dnns array C Note: This parameter is not applicable for QoS sustainability analytics.
dnais array C Note: This parameter is not applicable for QoS sustainability analytics.
event NwdafEvent M Indicates the subscribed event. The value for QoS sustainability analytics is "QOS Sustainability".
extraReportReq EventReportingRequirement O The additional event reporting requirements information.
ladnDnns array M Note: This parameter is not applicable for QoS sustainability analytics.
loadLevelThreshold Integer C Note: This parameter is not applicable for QoS sustainability analytics.
