5.11 AIoT Device Context in AIOTF
The AIOTF supports management of the AIoT Device context information locally. The AIoT Device context includes e.g. the AIoT Device Permanent Identifier, the last known RAN Reader information, the last known UE Reader information, RAN AIoT Device NGAP ID, Event Subscription Information, AIoT Device Type, DO-A Capable AIoT Device Temporary Identifier, etc. The last known RAN Reader information can be used to support the AIOTF to perform RAN Reader selection as defined in clause 5.3.3. The last known UE Reader information can be used to support the AIOTF to perform UE Reader selection as defined in clause 5.3.3a.
Table 5.11-1 below describes information storage structures for AIoT Device context.
Table 5.11-1: AIoT Device Context in AIOTF
| Field | Description |
|---|---|
| AIoT Device Permanent Identifier | Uniquely identifies the AIoT Device. |
| Last known RAN Reader information | Indicate the last known RAN Reader that serves the AIoT Device. |
| Last known UE Reader information | Indicate the last known UE Reader that serves the AIoT Device. |
| RAN AIoT Device NGAP ID | Indicate the RAN AIoT Device NGAP ID used to transfer the NGAP AIoT Command messages towards the AIoT Device between AIOTF and NG-RAN. |
| Event Subscription Information | Single or a list of event subscription information, each of which includes subscription requester ID (i.e., NEF ID or AF ID), the subscribed event ID (i.e., Uplink Application Container Transfer event, DO-A capable AIoT Device Reachability notification), Notification Endpoint and subscription correlation ID. |
| AIoT Device Type | Indicate the type of the AIoT Device, i.e., indicating AIoT Device is a DO-A Capable AIoT Device or not. |
| DO-A Capable AIoT Device Temporary Identifier | DO-A Capable AIoT Device Temporary Identifier allocated by the AIOTF. |
NOTE 1: When to erase the stored AIoT Device context is up to implementation and local configuration.
NOTE 2: Event Subscription Information, DO-A Capable AIoT Device Temporary Identifier are only applicable to DO-A Capable AIoT Devices.
NOTE 3: The last reader that serves the AIoT Device is reflected either in Last known RAN Reader information or Last known UE Reader information.
