CAPIF Integration with OAI Network Exposure Function

This demo will demonstrate the integration of CAPIF (Common API Framework for 3GPP Northbound APIs) with EURECOM's OAI Network Exposure Function (NEF), validated through a practical use case. EURECOM has developed a cloud-native, containerized architecture for its NEF, which integrates seamlessly with CAPIF. This CAPIF API Provider microservice embedded in the NEF fully supports the key functionalities defined by 3GPP, including the API Management Function (AMF), API Exposure Function (AEF), and the API Publishing Function (APF). The CAPIF-enabled NEF will be deployed within a 5G network, along with vertical applications (API Invokers) and the OpenCAPIF framework. During the demo: • The NEF will register with an OpenCAPIF instance and publish its APIs. • A vertical application, operating outside the PLMN trust domain, will request user location dat. It will discover and consume NEF APIs via OpenCAPIF. • Simultaneously, the network operator will use another application to retrieve logging and auditing data, facilitated by OpenCAPIF. This information will enable the operator to accurately charge the vertical for API usage, based on the volume and type of calls made. This demo will highlight the seamless interaction between CAPIF, NEF, and external application functions, showcasing the value of standardized API management and exposure in 5G networks.
