McKinney, TX (Nov 6, 2017) – Developing Solutions has added the Nu ReSTful interface application to its dsTest suite of 5G next generation core interface applications,  which now include the Open Mobile Alliance™ (OMA) specified Representational State Transfer (ReSTful) Network Application Programming Interfaces (APIs), Nt interface, and our CIoT/NB-IoT interface applications.

The Nu Interface between the Services Capability Exposure Function (SCEF) and the Packet Flow Description Function (PFDF) is used by the  SCEF to provision PFDs to the PFDF that have been received from the Service Capability Server/Application Server (SCS/AS), and for reporting the result of the PFD provisioning from the PFDF to the SCEF.
