The NRD-AF (Network-Resource-Driven Application Function) is Slicce's revolutionary application function designed to simplify the creation of complex, event-driven services on your modern telecom network. Built on our core Cloud Communication Engine architecture, NRD-AF combines the power of the 3GPP Common API Framework (CAPIF) with an intuitive low-code programming environment, enabling ultra-fast innovation and monetization.

The Single Endpoint Application Function uses a single HTTP Request/Response to implement a service logic in a mid-call trigger. It is extremely easy to add a new service to this application function but the service capabilities are limited to a single mid-call trigger per session. Some examples of services that are pre-integrated in the application function:

• Number translation service

• Whitelist/blacklisting

• Optimal call routing

These services are implemented using the mid-call triggers of the CAP-AEF, INAP-AEF or/and ISC-AEF so the AF can serve circuit switch or packet switch calls or messages on mobile or fixed line networks.

The Multi Endpoint Application Function uses the one or more entire API set to implement a service. The AF will be triggered by the initial trigger point of the interface it is subscribed to, and it will be responsible for the entire continuity of the call flow until its end. Some examples of services that are pre-integrated in the application function:

• Multi-ring

• Caller ringback tone

• Interactive call screening

• Branded calling

These services are implemented using CAP-AEF, INAP-AEF or/and ISC-AEF so the AF can serve circuit switch or packet switch calls or messages on mobile or fixed line networks.
