What does the Telco need?

• Best at connecting

everything on the planet

• Diversify offering new

products and services which

build on key competencies

• Procure companies that

strategically enhance their

offering,

• Requiring:

• Open Flexible Architecture

© 2017 TM Forum | 3

Zero point to point integration

Services are exposed through standard APIs

• Any component or service can be externalizable

with little additional effort

• Creating a dynamic flexible architecture where

new services or new business models can be

realised

• This is achieved by decoupling all functional

groupings

Component based with Open APIs

• Build from loosely coupled standardised

components with industry agreed boundaries

– Supports Multi vendor and Open Source projects

• Components expose metadata to automate

lifecycle management

– Packaging, automatic discovery etc.

• Extension of Frameworx to provide an industry

standard language to define components

API Component Suite

A highly cohesive set of APIs supporting resources (entities)

coupled with other resource entities in the API Suite enabling end to end

scenarios (execution flows)

A Component Suite Business Service IS a set of Functions exposed by

participating microservices enabling the execution of an-end goal (Functions can be operations,

notifications, …)

API component suite is focusing on the dependencies and pre-conditions for using the functions in end to end scenarios (enabling the cohesive and

consistent execution of a set of Functions)

Dependencies and pre conditions are normally satisfied by the presence of

APIs and resources providing the required information or operations for

proceeding to the next step

An API Component Suite is considered conformant if it provides all the capabilities (operation, events,

resources) required by the end–end scenarios AND if it provides the

means for accessing the supporting component services (schema registry,

security etc….)
