1. 3GPP SA5 Inputs for NFV Information Modelling Workshop
January 13-14, 2016
Louisville, CO

2. 3GPP SA5 Telecom Management ToR
SA WG5 will specify the requirements, architecture and solutions for provisioning and management of the network (RAN, CN, IMS) and its services. The WG will define charging solutions in alignment with the related charging requirements developed by the relevant WGs, and will specify the architecture and protocols for charging of the network and its services.
The WG will ensure its work is also applicable to the management and charging of converged networks, and potentially applicable to fixed networks. The WG will coordinate with other 3GPP WGs and all relevant SDOs to achieve the specification work pertinent to the provisioning, charging and management of the network and its services.

11. Cooperation with NGMN & TM Forum (2/6)
TS Fixed Mobile Convergence (FMC) Federated Network Information Model (FNIM)
The Federated Network Information Model allows a number of standards and specifications generated by different organizations to function together to bring greater coherence to the management of converged networks and hence reduce operations costs.
TS Fixed Mobile Convergence (FMC) Federated Network Information Model (FNIM) Umbrella Information Model (UIM)
The UIM is the part of the FNIM that represents the agreed model structures that 3GPP SA5 and TM Forum use (via “specific linkages” including inheritance, mappings and other derivations) for the definition of their respective Domain/Technology-specific concrete classes.
The use of UIM maximizes the probability of the Domain/Technology-specific concrete classes being semantically consistent, a necessary characteristic for FMC.

12. Cooperation with NGMN & TM Forum (3/6)
TS Fixed Mobile Convergence (FMC) model repertoire
This document defines how UML should be used to specify technology neutral Information Models (i.e. object classes, attributes, associations, association classes, stereotypes, data types) for Fixed Mobile Converged (FMC) management interfaces.
ITU-T SG2 have decided to include in their Requirements/Analysis methodology which is aligned with SA5.
TR Fixed Mobile Convergence (FMC) 3GPP / TM Forum concrete model relationships and use cases
This document describes operator use cases and requirements requiring some harmonization between 3GPP and TM Forum models. Overlaps and gaps of the 3GPP and TM Forum models are highlighted.
TR Fixed Mobile Convergence (FMC) Federated Network Operation Model (FNOM) Umbrella Operation Model (UOM)
The Umbrella Information Model (UIM) define the common model artifacts that will be used by the SDOs as a basis for their specific Fixed Mobile Converged (FMC) model instances. In addition to the UIM containing common “super classes” (incl. their attributes and associations), this document contains the common “interface super classes” (incl. their operations and notifications).

13. Cooperation with NGMN & TM Forum (4/6)
Output of Multi-SDO JWG on Converged Management PM Interface definitions
TR Fixed Mobile Convergence (FMC) Metadefinitions for Measurements and KPIs
This document defines the metadata for Performance Management (PM) performance measurements (KPIs and counters). The definition enforce consistency in description of all standardized performance measurements by various SDOs and organizations involved in the Management of Converged Networks.
This consistency facilitates encoding and decoding of performance measurements exchanged via management protocols and/or stored in databases or files.

16. 3GPP SA5 views on NFV modeling (1/3)
The following diagram extracted from NFVIFA(15) r4 gives the context of 3GPP views presented in the next slides
Application View
Outside of ETSI NFV scope
Logical View

17. 3GPP SA5 views on NFV modeling (2/3)
Class relations regarding Vnf/Vnfc
ManagedFunction is a kind of Function_ of 3GPP TS (see slide 14). Vnf/Vnfc are standard terms in ETSI NFV specifications.
The specifications of the bilateral relation-1 & relation-2 are subjects of investigation by the model harmonization activities. For example:
The synchronization of ManagedFunction attribute(s), including identifiers (or Distinguished Names), with the corresponding attribute(s) of Vnf for Relation-1 or Vnfc for Relation-2.
Dependencies of the life cycle states of ManagedFunction and Vnf/Vnfc instances.

18. 3GPP SA5 views on NFV modeling (3/3)
View on VNF
VNF is composed of two main parts:
An application-related part and
A virtualization-related part.
Use of the term ‘platform’ is under discussion.

19. 3GPP SA5 recommendations (1/2)
ETSI NFV is responsible for modeling the ETSI logical view.
3GPP SA5 is responsible for modeling the “application-specific aspects” of all 3GPP defined VNFs. 3GPP SA5 will use the current 3GPP SA5 methodology for the production and maintenance of 3GPP SA5 specifications for management of mobile networks that includes VNFs.
3GPP SA5 does not recommend to conduct model harmonization work between 3GPP SA5 defined managed function (e.g. VNF) application-specific model and all other SDO-defined application-specific models.

20. 3GPP SA5 recommendations (2/2)
3GPP SA5 recommends to harmonize views on the following aspects among ETSI ISG NFV, 3GPP SA5 and all other related SDOs:
Relation-1 (relation between ManagedFunction and Vnf)
Relation-2 (relation between ManagedFunction and Vnfc)
3GPP SA5 recommends to have a clear separation of the management protocols and the information that the protocols carry (as done in 3GPP SA5 IRP methodology).
3GPP SA5 recommends SDOs to use the 3GPP-TM Forum Umbrella Information Model as the base for SDOs’ model harmonization work.
