Taught in 2. What an Ambient IoT system is made of (Ambient IoT — a tag with no battery, quick start).
The AMF performs the following functions when the NG-RAN and the AIOTF communicate indirectly via an AMF:
- Relaying signalling for AIoT service (including e.g., inventory/command messages) between NG-RAN and AIOTF transparently.
- Providing transparent transport for AIoT NAS messages between AIoT Device and AIOTF.
