4.5.6 NRF

Taught in 2. What an Ambient IoT system is made of (Ambient IoT — a tag with no battery, quick start).

In addition to the functions defined in TS 23.501 [3], the NRF performs the following functions:

  • Support of the AIOTF NF type and its corresponding NF profile. The NF profile includes the AIOTF ID, FQDN or IP address, NF type and the serving area information of the AIOTF.

NOTE: The serving area information of the AIOTF is constructed by the sum of the supported AIoT serving area of the NG-RAN nodes that are directly or indirectly connected to the AIOTF.

  • Support of AIOTF discovery based on Target Area information.
  • Support of the ADM NF type and its corresponding NF profile. The NF profile includes the ADM ID, FQDN or IP address, NF type, the supported Domain Information of AIoT Device Permanent Identifiers, the supported AIoT Device Permanent Identifier ranges, and optionally the supported AF IDs.
  • Support of ADM discovery based on parameters as specified in clause 5.3.2.

The AIOTF(s) and the ADM register or update its NF profile in the NRF by means of the method as defined in clause 4.17.2 of TS 23.502 [4].
