28.5453GPPFault Supervision (FS)Management and orchestrationRelease 17TS

The authorized MnS consumer request VNF application alarms and VNF instance alarms related to virtualized resource from MnS producer by consuming the fault supervision MnS. MnS producer obtain the VNF application alarms (including affected VNF/VNFC instance identifier and detailed VNF alarm information) from the VNF, and the VNF instance alarms related to virtualized resource (including affected VNF/VNFC instance identifier and detailed NFVI/VM alarm information) received from the VNFM. Based on the above obtained alarms, MnS producer can correlate the VNF application alarms and the VNF and/or VNFC alarms related to virtualized resource according to affected VNF instance identifier and/or VNFC instance identifiers. The detailed procedure for virtualized resource alarm correlation procedure see corresponding procedure of NE alarm correlation made by EM in the context of NFV described in TS 28.516[4] and the MnS producer act as the role of EM.

The authorized MnS consumer requests NSSI alarms including alarm reports related to virtualized resource by consuming the fault supervision MnS. The MnS producer should collect alarm report related to virtualized resource according to affected VNF instance identifier corresponding to the NF instance in the NSSI.
