5.7.2 AIoT Device Permanent Identifier

Taught in 4. What the security protects, and what it leaves open on purpose (Ambient IoT — a tag with no battery, quick start).

In order to support the AIoT feature in 5G System, a globally unique AIoT Device Permanent Identifier shall be allocated to each AIoT Device. An AIoT Device Permanent Identifier is assigned either by an operator or by a third party. The AIoT Device Permanent Identifier is used to identify an AIoT Device and locate the entity where the AIoT Device related information is stored.

NOTE 1: How to configure an AIoT Device with the AIoT Device Permanent Identifier is out of scope of this specification.

The AIoT Device Permanent Identifier includes the following components:

  • The ID Type, including:
    • Information indicating whether a PLMN ID is included.
    • Information indicating whether a NID is included.
    • Information indicating whether a Third Party Identifier is included.
    • Identification Information Type, indicating whether the Identification Information contains an EPC or unstructured information.
    • Information indicating the length of Identification Information.
  • The Domain Information includes none, one or more of the following:
    • A PLMN Identifier (i.e., MCC and MNC) as specified in TS 23.003 [6] when the information in the ID type indicates it is included
    • A Network Identifier (NID) as specified in TS 23.003 [6] when the information in the ID Type indicates it is included.
    • A Third Party Identifier used to identify a third party when the information in the ID Type indicates it is included.
  • The Identification Information is used to distinguish different AIoT Devices within the scope identified by Domain Information (if available) and can contain either:
    • An EPC, as defined in clause 14 of GS1 TDS Release 2.1 [7].
    • Unstructured information, where the contents are defined by the allocator.

An operator allocated AIoT Device Permanent Identifier should include the identifier of the network for the operator. The identifier of the network is present as either a PLMN Identifier, NID or both in the AIoT Device Permanent Identifier.

A third party allocated AIoT Device Permanent Identifier may include none or any combination of at least one of the following: a PLMN Identifier, NID or Third Party Identifier.

NOTE 3: The length of ID Type, PLMN Identifier (if present), NID (if present) and the Third Party Identifier (if present) components are fixed. The length of the Identification Information is variable. The details are specified in TS 23.003 [6].

NOTE 4: When the Domain Information is empty, the AIOTF uses, e.g., Identification Information (i.e. EPC) to discover and select the ADM instance or the external server for the AIoT Device Profile Data.

The following lengths are supported for the Identification Information in an AIoT Device Permanent Identifier: 32 bits, 64 bits, 96 bits, 128 bits, 256 bits and 496 bits.

NOTE 5: The encoding for the length of the Identification Information enables additional shorter or longer fixed lengths to be supported in the future.
