The increasing demands on OSS/BSS

Greg Tilton, CEO, DGIT Systems

© 2017 TM Forum | 2

Agenda

▪ How have OSS & BSS requirements changed and how are

needs evolving with the pervasion of digital services?

▪ Moving towards next-generation OSS for a virtualized and

hybrid network

▪ OSS & BSS Standards – why the industry needs them,

where we currently stand.

NFV and NSO enablers

▪ Industry projects TMF, ONAP, MEF have concluded that the industry should use a generic interaction

model present both network and compute resources

▪ All the proposed models agree on the need for autonomous resource functions (RFs) to enable NFV

▪ The BSS/OSS is then presented with a reduced and standardized instruction set for managing resource

functions

▪ This reduced instruction set is made possible through dynamic APIs where API payloads are abstracted

and governed by meta-data

Omni Channel a basic premise of new BSS (GB994)

▪ Channel Choice based on Customer Preference

Dynamic Web Portal

TMF Open APIs

Front of House

▪ Channel Hopping

‘State’ is maintained behind the API

Stateless channels can be used interchangeably

▪ Deliver in Context

Catalogs make the correct offers available to correct parties

Recommendations for Customer and Marketplace Channels

▪ Omni-Channel models will seek out the most convenient engagements

with customers and partners in the marketplace, we need to empower

the customer experience managers within the service providers

▪ “Headless” modes from BSS/OSS with full dynamic APIs expose allow

the service provider to take full control of the customer experience.

There is a price / experience trade off to make

▪ It is foolish and unnecessary to throw away the lifecycle cost and agility

benefits of being catalog driven in the interests of short term experience

improvements

“A common set of business operations and APIs can be combined with meta-data

instantiation of services to support any service type, NFV, SDN, IaaS, SaaS, IoT, Fibre as

a Service.”

Dynamic APIs to support an Omni Channel Model

Dynamic payload in APIs governed by meta data

Common APIs to support best practice touchpoints

Meta is data data which defines data, also called:

Templates

Specifications

Model Driven

Catalog Driven

Control Plane

Lots of standard and non standard meta data formats are

available:

TMForum SID Specifications (used by NBNCo)

JSON Schema via hypermedia (MEF Sonata and preferred by

web developers)

Tosca (OASIS standard from the cloud world)

Yang/Netconf (extending templating from traditionally

networking)

NOT TO WORRY WE CAN CONVERT / ADAPT BETWEEN FORMATS !

Industry Catalog (ie MEF)

ProductOrder API

JSON schema extensions are used to

describe products

The buyer calls the

catalog entry using URL

in the message

Service Provider Catalog

Order Orchestrator

http://unitemplate1.1.mef.net

http://evctemplate1.3.mef.net

http://specialproduct2.0.acmeco.net

The B2B buyer calls the

catalog entry using

URL/hyperlink in the

message simplifying

catalog integration

Catalog’s and Wholesale Omni-Channel

Order API

Web Portal

The Dynamic Portal calls

the catalog and renders

screens from Templates

Realisations and Next Steps !

▪ New BSS/OSS needs to enable efficient customer experience management

▪ New BSS/OSS now needs to manage the intelligent network and compute presented by NFV & NSO

▪ New BSS/OSS is built to be more plastic through dynamic APIs, catalogs, dynamic inventories and meta-data management
