Section: 5.15.11.4 Network Slice status notifications and reports to a consumer NF
Content: A consumer NF (e.g. AF, Primary NSACF) can subscribe with the NSACF for Network Slice status notifications and reports. Upon such subscription, the corresponding NSACF in different NSAC architecture as defined in clause 5.15.11.0 can provide event based notifications and reports to the consumer NF (e.g. to AF via NEF) related to the current number of UEs registered for a network slice or the current number of UEs with at least one PDU Session/PDN Connection in the case of EPC interworking or the current number of PDU Sessions established on a network slice. NOTE: The Primary NSACF subscribes Network Slice status from all the NSACF(s) it contacts with for the update of the maximum number of UE or PDU session configured at the NSACF.
