A CM procedure for PNFs ,
PNFID, Target SW version, …
SDC SO
Operator
(e.g. VID, Timer)
Portal
Scenarios of PNF SW management:
Regular NE software version upgrade. Operator could upgrade the SW to the specific version for several PNFs
To satisfy the radio interface coverage in some area for the specific RAT , operators could change PNF SW between different RATs at some PNFs
To increase the RAN capacity for the specific RAT, operators could change PNF SW between different RATs at some PNFs
BTW: Orchestrator could verify the SW is valid or not

Content
Description
pnfdId M 1
Identifier
Identifier of this Pnfd information element. It uniquely identifies the PNFD.
functionDescription
String
Describes the PNF function
provider
Identifies the provider of the PNFD.
version
Version
Identifies the version of the PNFD.
pnfdInvariantId
Identifies a PNFD in a version independent manner. This attribute is invariant across versions of PNFD.
name
Provides the human readable name of the PNFD.
pnfExtCp
1..N
PnfExtCpd
Specifies the characteristics of one or more connection points where to connect the PNF to a VL. See clause
security
0..1
SecurityParameters
Provides a signature to prevent tampering.
geographicalLocationInfo
Not specified
It provides information about the geographical location (e.g. geographic
coordinates or address of the building,
etc.) of the PNF. The cardinality 0 is used when the location is unknown.
Descriptor related information
PNF related information

6. PNF Resource definition in PnP Description
PnP step 1&4 Description
RESOURCE DECLARATION –A user on the VID performs a Resource Declaration. This uses the Service definition created in SDC. The user on the VID can define known information about the PNF. The user can (optional) provide the following information
PNF RESOURCE Definition
Resource Type –Type of Resource. NEW type: PNF (pre-defined in SDC)
NAME–Name of the PNF type
CATEGORY–e.g. Infrastructure
TAGS–User-definable tags (default name of the PNF)
DESCRIPTION–Textual description
CONTACT ID –Designer (user of ONAP)
VENDOR–PNF Vendor (e.g. Nokia)
VENDOR RELEASE –Vendor release
VENDOR MODEL NUMBER–PNF Model value (link to A&AI)
EVENTS–Monitoring Event definitions. Define design-time templates. CLAMP (runtime monitoring), DCAD (design time design template attach to VNF). Define templates & attach them.
Note: The user may provide whatever information in the above fields they know.
Note: Consumer vs Enterprise deployments. Consumer systems pre-registered, distributed throughout a region. For a consumer deployment you might not know the MAC address/Serial number (PND IF) until the PNF connects to ONAP.

7. A Potential PNF template for PNF CM&SW management in Casablanca
In order to enhance the feasibility and flexibly of PNF orchestration by using SDC and SO, a potential PNF template is introduced
Attributes of a PNF Descriptor, for identifying and maintaining the PNF Template
PNFD Properties definition, based on ETSI PNFD related information
PNF Template

10. Potential PNF template Onboarding workflow in ONAP
Description of a Potential PNF template Onboarding workflow in ONAP:
Step1: User onboards the PNF template through VID. The parameters carried in the message could consist with the Resource Declaration, and a software list would be complemented
Step2: SDC distributes the PNF template to SO. SDC could do a PNF template verification to prevent tampering
Step3: SO registers the PNF information in A&AI

11. Potential PNF SW CM workflow in ONAP
Description of a Potential PNF SW CM workflow in ONAP:
Step1: User request SO to upgrade/change a PNF software. The target software version has been carried in the message
Step2: SO verifies if the target software is valid, the verification could be done in A&AI
Step3: A&AI replies the result of the software version verification
Step4: SO continue to complete the rest of the upgrading workflow
