4.3 Reference points

The AIoT Architecture contains the following reference points:

AIOT1: Reference point between the AIoT Device and the AIOTF.

AIOT2: Reference point between the NG-RAN and the AIOTF.

The following reference points show the interactions that exist between the NF services in the NFs. These reference points are realized by corresponding NF service-based interfaces and by specifying the identified consumer and producer NF service as well as their interaction in order to realize a particular system procedure.

AIOT3: Reference point between the AIOTF and the AMF.

AIOT4: Reference point between the AIOTF and the NEF.

AIOT5: Reference point between the AIOTF and the NRF.

AIOT6: Reference point between the AIOTF and the ADM.

AIOT7: Reference point between the ADM and the UDR.

AIOT8: Reference point between the ADM and the NEF.

In addition to the relevant reference points defined in TS 23.501 [3], in the case of AIoT, these reference points are as follows:

N1: Reference point between the UE and the AMF.

N2: Reference point between the NG-RAN and the AMF.

N8: Reference point between the AMF and the UDM.

N33: Reference point between NEF and AF.

N52: Reference point between the NEF and the UDM.
