4.5.3 AIOTF
Taught in 1. What Ambient IoT is: a network that reads tags with no battery (Ambient IoT — a tag with no battery, quick start), 2. What an Ambient IoT system is made of (Ambient IoT — a tag with no battery, quick start).
The AIOTF supports the following functions:
- Termination of AIoT NAS protocol with AIoT Device.
- Connectivity with an NG-RAN via a direct interface reference point or via an AMF.
- Support of AIoT service operations towards the AIoT Devices(s):
- Providing an interface to the AF (or via NEF) for AIoT services and authorizing the trusted AF's AIoT service operation requests.
- Triggering the NG-RAN to perform AIoT service operations towards the AIoT Device(s), and optionally determining and providing assistance information to the NG-RAN.
- Report the service operation results based on the local configuration or the request.
- NG-RAN selection and optionally a list of RAN Reader selection for AIoT service operations.
- AMF selection based on target area information when AIOTF connects to NG-RAN indirectly via an AMF.
- Correlation ID allocation corresponding to the AF service operation request.
- Retrieving AIoT Device Profile Data from ADM.
- Retrieving AF subscription data from ADM.
- Optionally AIoT Device context management.
- Perform aggregation of the AIoT service responses, determine and provide assistant for the AIoT aggregation in NG-RAN.
NOTE: Authentication of AIoT Devices related to AIOTF is defined in TS 33.369 [9].
