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.
© 3GPP 2012
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.

TS 32.107 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 28.620 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/Technologyspecific concrete classes being semantically consistent, a necessary
characteristic for FMC.

Cooperation with NGMN & TM Forum (3/6)
TS 32.156 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 32.156 in their Requirements/Analysis
methodology which is aligned with SA5.
TR 32.854 Fixed Mobile Convergence (FMC) 3GPP / TM Forum
concrete model relationships©and
use cases
3GPP 2012
• 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 28.820 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).

performance measurements (KPIs and counters). The definition enforce

measurements exchanged via management protocols and/or stored in
databases or files.

3GPP SA5 views on NFV modeling (1/3)
The following diagram extracted from NFVIFA(15)0001298r4
gives the context of 3GPP views presented in the next slides

3GPP SA5 views on NFV modeling (2/3)
Class relations regarding Vnf/Vnfc
© 3GPP 2012
ManagedFunction is a kind of Function_ of 3GPP TS 28.620 (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.

3GPP SA5 views on NFV modeling (3/3)
View on VNF
© 3GPP 2012
VNF is composed of two main parts:
• An application-related part and
• A virtualization-related part.
Use of the term ‘platform’ is under discussion.

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
© 3GPP 2012
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 SDOdefined application-specific models.
3GPP SA5 – NFV Information Modelling Workshop – January 2016

19
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 2012
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.
