name: PNF
full_form: Physical Network Function
context: NM needs to be able to add the non-virtualized part of gNB as PNF to a NS instance (see clause 4.2.4), remove the non-virtualized part of gNB as PNF from a NS instance (see clause 4.2.5) and replace the non-virtualized part of gNB as PNF in a NS instance (see clause 4.2.5) by using Update NS operation (see clause 7.3.5 of ETSI GS NFV-IFA 013 [3]) towards NFVO. However, the current Update NS operation does not support adding or removing PNF(s). So this is a gap between the 3GPP and ETSI ISG NFV. To support the 3GPP requirements above-mentioned and as described in clause 7.3.1, the Update NS operation needs to be extended to support adding PNF or removing PNF with parameters shown below: - Add PNF The pnfdId (see clause 6.6.2.2 of ETSI GS NFV-IFA 014 [5]) to identify the PNFD of the PNF (non-virtualized part of gNB) to be added. - Remove PNF The pnfdId to identify the PNFD of the PNF (non-virtualized part of gNB) to be removed.
description: A Physical Network Function (PNF) refers to a non-virtualized part of a network element, such as the non-virtualized part of a gNB. It is a component that provides specific network functions and can be added or removed from a Network Slice (NS) instance.
explanation: The context explicitly mentions PNF in relation to adding and removing non-virtualized parts of a gNB, indicating its role as a Network Function within the 3GPP specification.
