Network Exposure Function
For a programmable and open 5G
Nokia Network Exposure Function provides you with a robust platform for creating new services by consolidating APIs and presenting unified access to the API framework for both your developers and 3rd party developers.
- Secure exposure of network services (voice, data connectivity, charging, subscriber data, etc.) towards 3rd party application over APIs
- Developer environment and SDK for operator and community
- Service mashup for creating end-to-end offering by combining any of the network assets into your application
- Integration layer that connects your application to operator’s network.
The API framework is realized through a plug-in concept that makes it possible to create complex API-based services. You can add additional APIs over time, according to your needs. For those operators with multi-vendor cores, Nokia’s Network Exposure Function can expose APIs from other vendors’ network functions, by enabling the use of 3rd party plugins.
Key Features:
Enables external application to communicate with the 5G core’s Service Based Architecture (SBA) via APIs.
Secure, scalable, simplified and SLA compliant service capability exposure for events, data and functionality.
Advanced application capabilities (specialized application servers in NEF PaaS).
Adapts and transforms telecom network interfaces to RESTful APIs.

Use 5G API exposure function to build new differentiated services
API exposure in 5G
In the 5G new API ecosystem operators look at their network as a platform opening it to application developers. API exposure is fundamental to 5G as it is built into the architecture natively where applications can talk back to the network, command the network to provide better experience in applications.
The value of the 5G ecosystem
The ecosystem of service providers, industrial players, application developers and API vendors must innovate jointly to create differentiating successful new services. This open ecosystem must share SDKs, descriptions to support each other in this process.
5G’s Application development
Network Exposure Function beside fulfilling 3GPP requirements abstracts the capabilities of the network creating a programmable environment. Developers can create a new service logic introducing new APIs on the top of the standard ones tailormade for the business needs.
