If the current NF knows the old Model ID information, you can query other information associated with it through the Model ID in the query message, such as model training information, analytic ID list information, model priority information, etc. Or subscribe to subsequent updates and releases of the model, etc.

The interrogator information indicates which NF or terminal is requesting this Model ID.

The query message type identifier indicates that this is a query, subscription or unsubscription message. If it is a subscription, the subscription attribute needs to be included.

Subscription attributes include subscription type, subscription description, etc. The subscription type refers to whether the Model ID management unit is a periodic reply or an event reply. The subscription description refers to the period length of the periodic reply or the event description of the event reply. The event description refers to the event that will trigger the Model ID management unit to reply to the model information.
