3.1 Definitions

For the purposes of the present document, the terms and definitions given in TR 21.905 [1], TS 32.101 [5], TS 32.111-1 [7], TS 32.150 [8], TS 32.401 [6] and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905 [1].

Consumer Role: See service consumer in clause 5 of 3GPP TS 32.101 [5]. See consumer in ETSI GS NFV‑MAN 001 [3]).

LifeCycle Management (LCM): Defined in ETSI GS NFV 003 [4].

Note 1: How to define the lifecycle management of 3GPP network and entity is FFS.

Network Functions Virtualisation Infrastructure (NFVI): Defined in ETSI GS NFV 003 [4].

Network Functions Virtualisation Management and Orchestration (NFV-MANO): Defined in ETSI GS NFV 003 [4].

Network Functions Virtualisation Orchestrator (NFVO): Defined in ETSI GS NFV 003 [4].

NS: Network Service defined in ETSI GS NFV 003 [4].

NOTE 2: The NS defined by ETSI NFV documents is not equivalent to 3GPP services. The latter requires the former for network orchestration in case the network includes virtualized network functions.

Physical Network Function (PNF): Defined in ETSI GS NFV 003 [4].

Note 3: From 3GPP perspective, non-virtualized NE is a typical example of PNF.

Producer Role: See service producer in clause 5 of 3GPP TS 32.101 [5]. See producer in ETSI GS NFV-MAN 001[3]).

Scaling: Defined in ETSI GS NFV 003 [4].

Virtual Machine (VM): Defined in ETSI GS NFV 003 [4].

Virtualised Infrastructure Manager (VIM): Defined in ETSI GS NFV 003 [4].

Virtualised Network Function (VNF): Defined in ETSI GS NFV 003 [4].

Note 4: From 3GPP perspective, it corresponds to the application level function of NE, which is defined in 3GPP TS 32.101 [5].

Virtualised Network Function Manager (VNFM): Defined in ETSI GS NFV 003 [4].

Virtualised Network Function Package (VNF Package): Defined in ETSI GS NFV 003 [4].

VNF Healing: Defined in ETSI GS NFV-IFA010 [2].

3.2 Abbreviations

For the purposes of the present document, the abbreviations given in TR 21.905 [1] and the following apply. An abbreviation defined in the present document takes precedence over the definition of the same abbreviation, if any, in TR 21.905 [1].
