Legend:

  • AIoT Data: It is the application data exchanged between the AIoT Device and the AF.
  • AIoT NAS: The NAS protocol between AIoT Device and the AIOTF.
  • AIoT AS: It is between the AIoT Device and the NG-RAN as specified in TS 38.300 [5].
  • NGAP: Application Layer Protocol between the AIOTF and the NG-RAN as defined in TS 38.413 [10].
  • NGAP AIoT Information: It is the subset of NGAP information and is included in the NGAP messages over AIOT2 reference point.

The AIoT NAS messages between the AIoT Device and the AIOTF are transferred via the NG-RAN transparently.
