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 APP-C SW version: 5G_NR_**.**.abc EM SW version: 4G_LTE_**.**.xyz SW version: 4G_LTE_**.**.abc PNF PNF PNF PNF PNF

PNFD Definition in ETSI PNFD Definition in ETSI-NFV-IFA014v242 Attribute Qualifier Cardinality 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 6.6.4. 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

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.

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 attribute of PNFD … PNF Template TOSCA Model definition attribute of PNF … An enhancement of PNF SW description An example of PNF Template TOSCA model PNF NodeType definition, based on ETSI PNFrelated information and Resource declaration Software Description Attributes to describe a PNF, for identifying and orchestrating the PNF A PNF template consists of IEs relates to PNFD and IEs relates to PNF

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

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
