32、sibilities, are not exhaustive. 4.2 MO configuration procedure This procedure shows how to configure the attributes of the existing MO corresponding 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 insta

33、nce to EM, this request includes relevant parameters for the MO configuration. 2) When EM receives the MO configuration request, it configures the attributes of the existing MO. 3) EM responds the result of the MO configuration to NM.

34、g 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 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

35、 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 decides 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

36、 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 update of the MOI(s). ETSI ETSI TS 128 511 V14.0.0 (2017-07)73GPP TS 28.511 version 14.0.0 Release 14NOTE: The assumption of this scenario is that NM can know

37、 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 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 m

38、essage indicating the subject VNF has been scaled from VNFM. 2) EM decides the MOI(s) corresponding to the subject VNF instance need to be updated. 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)

41、e 4.4.1-1 illustrates the procedure of creating MO after the corresponding VNF instantiation is triggered by EM. Figure 4.4.1-1: MO creation after VNF instantiation (triggered by EM) 1) When the new VNF instance is allocated with virtualized resources and configured with non-application parameters s

42、uccessfully, VNFM sends a Notify (see clause 7.3.3 3), carrying VnfLifecycleChangeNotification information element to EM with attributes vnfInstanceId, status = “result“, operation = “instantiation“, lifeycleOperationOccurrenceId, affectedVnfc, affectedVl, and affectedVirtualStorage (see clause 9.5.

43、2 3) to indicate the end and the successful result of VNF instantiation, the parameter see clause 4.5 of 4. 2) EM creates the MOI(s) and sets attributes 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 o

44、f 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 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

45、 to a specified VNF instance. Operator, via NM, knows the identifier of the specific VNF instance via NM reception of the VNF instance instantiated notification. The figure 4.4.2-1 illustrates the procedure of creating MOI(s) for a specified VNF instance. NM EM 3. notifyObjectCreation VNFM 1. EM rec

The other configuration parameters are also included in the request if needed. 2) EM creates the MOI(s) and sets the relevant MOI(s) attribute with the VNF Instance identifier referring to the specified VNF instance.

It is assumed that a MO has been created to represent a VNF instance, and EM has subscribed to receive the VNF lifecycle change notification from VNFM: 1) VNFM sends a Notify (see clause 7.3.3 3), carrying VnfLifecycleChangeNotificati
