Option 1: To unsubscribe for a specific event for a group of UE(s) or any UE accessing a combination of (DNN, S-NSSAI).
Option 2: To subscribe for a specific event for a group of UE(s) or any UE accessing a combination of (DNN, S-NSSAI).
Option 3: To update the subscription correlation ID for a group of UE(s) or any UE accessing a combination of (DNN, S-NSSAI).
Option 4: To retrieve the operation execution result indication for a group of UE(s) or any UE accessing a combination of (DNN, S-NSSAI).
Explanation: The Npcf_EventExposure_Unsubscribe service operation is used by the NF consumer to unsubscribe for a specific event for a group of UE(s) or any UE accessing a combination of (DNN, S-NSSAI), as indicated in the description of the service operation.
