We often get questions about 5G Service Based Architecture. Luckily, we have a tutorial that we can redirect people to. It's available here and the video just crossed 50K views. One of the questions that people often want to understand, is about the Application Function (AF) and how does it fit in the Applications Architecture.
To explain this, we made a tutorial. The slides and videos are embedded below. In that we have used the examples from our XR, V2X and Private Networks tutorials. All links are available at the bottom of this post.

The slides show that the native applications use NRF and untrusted applications use NEF but that distinction does not follow 3GPP document. XR and V2X applications are native but they use NEF to get access to 5G core. please review this.
ReplyDeleteThe pictures are from 3GPP documents. TR 26.298 says, "Functions in external DNs may only communicate with 5G Core functions via the NEF using N33."
ReplyDeleteThanks for nice explanation..Can we get any call flow reference as well
ReplyDeleteI can not find any document "TR 26.298"
ReplyDeleteSorry, TR 26.928
