5. CAMARAAPIArchitecture
Abstraction from Network APIs to
Service APIs is critical:
●Hide telco complexity
●Make APIs developer (no telco
expertise) friendly
●Fulfil data privacy and regulatory
requirements
●Facilitate application to network
integration
* Camara APIs could be consumed either by
aggregators or directly enterprises

6. ● 7
CAMARA
Scope
We differentiate between 3 types of Northbound APIs:
• Service APIs: APIs intended for end consumers and
integrated by developers to invoke a certain telco
capability.
• Service Management APIs: APIs intended for end
consumers to manage or get data about offered Service
APIs in application runtime, e.g., check service availability
or performance information.
• Operate APIs: Operational and maintenance APIs provided
by a telco to channel partners for the purpose of service
fulfillment and assurance to their [channel partner]
customers. This may include service provisioning for a
mobile user, technical API performance monitoring, fault
ticketing, information exchange such as product catalog,
pricing, settlement, etc.
Service APIs and Service Management APIs
are in scope of CAMARA. Operate APIs are out of
scope of CAMARA (these are already covered by
other SDOs = Standards Development
Organizations like TM Forum).

7. ● 8
CAMARA
Scope
Hyperscalers and aggregators have the possibility to create own enriched products based on the
CAMARA APIs and expose that in addition to the CAMARA APIs.

8. ● 9
CAMARA
Scope
CAMARA project defines
CAMARA APIs.
TMForum develops the Operate
APIs.
Several SDOs cover the different
technology domains that provide
the telco capabilities.
More details can be found in the
whitepaper “The Ecosystem for
Open Gateway NaaS API
Development” (jointly published
by GSMA, CAMARA, Linux
Foundation and TMForum)
available here.

9. GSMAOpenGateway
● A GSMA-led initiative in the telco sector that
seeks to transform the communications
networks into platforms
● Open up telco capabilities in an
interoperable, intuitive and programmable
way.
● A framework of common network APIs
designed to provide universal access to
operator networks for developers
● Launched with 8 APIs and the support of 21
mobile network operators in MWC’23

13. Quality on Demand

15. Overview
● Current version: 0.9.0
● Simplify and enhance NEF AsSessionWithQos
– v0.8.0
● Parameterized
● No IP Filter Rule required
● Assigned UE IP address supported
● Only a single flow supported
● Duration is added
– v0.9.0
● QoS status and corresponding notification
● Support NATed UE IP address
● QoS profile discovery

17. CAMARAQoDAPI–QoSProfileDiscovery
● CAMARA QoD API is a developer-friendly service API for accessing 3GPP AsSessionWithQos capability
● CAMARA QoD API v0.9.0 introduces a QoS Profile Discovery endpoint
– For developers to know the characteristic of a specific QoS profile
– For developers to discover the proper QoS profile which fulfil the QoS requirements

18. CAMARAQoDAPIBenefit/Valuecomparingwith3GPPAPI
CAMARA QoD API is a developer-friendly service API to expose the QoS capability with following
main benefits comparing with 3GPP defined API,
● Simplification:
- Only IP flow
- Only single flow
- Notification endpoint is optional
●Enhancement:
- Session duration
- QoS Profile and discovery
- NATed IP
● Transformation:
- Easy to understand concepts/terminologies
- No IPFilter Rules
- QoS status
