The S-NSSAI(s) supported by the AMF on a per TS basis may be changed and the change needs be updated to NSSF. The AMF may subscribe to the notification of any changes to the NSSAI availability information updated by another AMF on a per TA basis.

The up-to-date and effective S-NSSAI availability information are fundamental to support network slicing for 5G, therefore the performance of S-NSSAI availability service needs to be monitored.
