34、ding to a VNF instance. Main steps for MO configuration: 1) NM sends a request of configuring the attributes of the existing MO corresponding to a VNF instance to EM, this request includes relevant parameters for the MO configuration. 2) When EM receives the MO configuration request, it configures t
35、he attributes of the existing MO. 3) EM responds the result of the MO configuration to NM. Figure 4.2-1: MO configuration procedure 4.3 Procedure of updating MOI(s) after a VNF is scaled This procedure shows how to update corresponding MOI(s) after a VNF is scaled. The procedure can be triggered by
36、NM or EM. Scenario 1: Triggered by NM The use case for scenario 1 is in clause 6.4.5 of 2. In this case, the main steps of the procedure are: 1) NM receives the message indicating the VNF instance has been scaled from NFVO (refer to step 3 of procedure in clause 4.2.3.3 of TS 28.526 4). 2) NM decide
37、s the MOI(s) corresponding to the subject VNF instance need to be updated. 3) NM sends a request to EM to update the MOI(s) corresponding to the subject VNF instance. 4) EM updates the attributes of the MOI(s) corresponding to the subject VNF instance. 5) EM sends the notification to NM about the up
38、date of the MOI(s). ETSI ETSI TS 128 511 V15.0.0 (2018-07)73GPP TS 28.511 version 15.0.0 Release 15NOTE: The assumption of this scenario is that NM can know the relationship between VNF instance and corresponding MOI(s). Figure 4.3-1: Procedure of updating MOI(s) after a VNF is scaled (Triggered by
39、NM) Scenario 2: Triggered by EM The use case for scenario 2 is in clause 6.4.6 of 2. In this case, the main steps of the procedure are: 1) EM receives the message indicating the subject VNF has been scaled from VNFM. 2) EM decides the MOI(s) corresponding to the subject VNF instance need to be updat
40、ed. 3) EM updates the attributes of the MOI(s) corresponding to the subject VNF instance. 4) EM sends the notification to NM about the update of the MOI(s) plus the related information abstained in step 1.

Figure 4.4.1-1: MO creation aft

45、tributes of the created MOI(s) (i.e. VNF Instance Id) referring to the new VNF instance. 3) EM sends a notifyObjectCreation 6 to NM to indicate the result of the MO creation to NM. 4) EM may configure the attributes of the created MOI(s) if needed and send NM the attributeValueChange 6 notifications
46、 if NM has subscribed to the attributeValueChange notification. 4.4.2 MO creation for a specified VNF instance Operator wants to create MOI(s) corresponding to a specified VNF instance.
