This document discusses how communication service providers (CSPs) are leveraging open APIs. It outlines several open API initiatives led by organizations like the Linux Foundation and TM Forum. The TM Forum has defined 54 APIs for CSP operational functions. Initiatives like ONAP and MEF are aligning on external APIs. The document suggests CSPs could expose APIs for infrastructure, core communications services, IT services, and identity management. Open APIs may help CSPs adopt a platform business model and remain relevant to enterprise and consumer customers. It poses questions about adoption of open APIs by traditional OSS/BSS systems and vendors.

• Linux Foundation’s Open API Initiative
• Led by SmartBear, Apigee, Google, IBM, Microsoft, PayPal and
others
• Based on Swagger, an API approach based on Representational
State Transfer (REST) , Simple Object Access Protocol (SOAP), Web
Services and Remote Procedure Calls (RPC).
• TMForum’s Open API Manifesto
• Led by Axiata, BT, China Mobile, China Unicom, MTN, NTT, Orange,
Telefonica, Telstra, Vodafone, plus many vendors.
• 54 APIs for CSP operational functions e.g. creating a trouble ticket,
collecting service usage data, service ordering.
• Uses Swagger for modelling along with other tools e.g. JSON
schema.
Open API Initiatives

@LIGHT_READING #CNGEUROPE
• ONAP
• ONAP project has collaborated with TM Forum on external APIs,
ensuring they can communicate seamlessly with the ONAP
platform.
• Other TM Forum Open APIs that were incorporated in ONAP’s
Beijing Release were Service Catalog and Service Inventory.
• MEF
• MEF and TM Forum are collaborating on APIs for the Lifecycle
Services Orchestration (LSO) interface between operators (Sonata)
• 8 API definitions are planned: address validation, service
availability, ordering, quoting, billing, assurance, testing and
change management
• AT&T, Orange, Colt and CableLabs will make API contributions
Who Is Aligned?

Customer Management: Managing Commercial relationship with Customers
Masters Products, CRM, Billing, Commercial Orders
Service Management: Manages end-to-end Customer-Facing Services built by
service-chaining multiple Technical Components (Resource-Facing Services) together.
Resource Management: Management and Orchestration of component services
(Resource-Facing Services) from each technology domain.
Technology Management: Management of the physical and virtual application and
Infrastructure technologies
Application & Transmission: physical and virtual application and Infrastructure
technologies

• Infrastructure control: expose bandwidth on demand,
cloud provisioning and application optimization
capabilities.
• Core communications services: WebRTC, RCS, streaming
video and combinations e.g. video conferencing + IPTV, or
PBX/IVR + unified communications.
• IT services: BSS and OSS functions, e.g. carrier billing,
charging and in-app payment, authentication, subscriber
profiles.
• Identity Management: provide access & security to users’
accounts & safely enable app to access & use subscriber
resources (contact lists, location, etc.).

What Should CSPs Expose Via APIs?

7. P R E S E N T E D B Y :
@LIGHT_READING #CNGEUROPE
• Open API concept provides lingua franca for
industry collaborative initiatives like ONAP.
• Tapping into community of global application and
cloud providers and exposing their own
capabilities, APIs will also allow CSPs to adopt the
platform business model.
• Platform model is arguably key to remaining
relevant to enterprise and consumer customer
bases.
Can APIs Boost Business Transformation?

8. P R E S E N T E D B Y :
@LIGHT_READING #CNGEUROPE
• Do traditional OSS systems (e.g. fulfilment,
assurance) need to use the same Open API
frameworks as ONAP and MEF?
• Do BSS systems need to use the same API
frameworks as OSS?
• Why hasn’t all of the vendor community signed up
to the TMF’s Open API manifesto?
• Why haven’t more CSPs signed up?
More Food For Thought
