    Abstract: An information processing device includes: a memory and, at least one processor coupled to the memory. The processor performs operations. The operations includes: applying inference target data in which at least part of data includes a first target object to a first learned model to infer the first target object as primary inference; generating aggregated data that is data having a smaller quantity than the inference target data by using the first target object inferred in the primary inference; generating a correspondence relation between a position of the first target object in the inference target data and a position of the first target object in the aggregated data; applying the aggregated data to a second learned model to infer the first target object as secondary inference; and inferring the first target object by using the first target object in a result of the secondary inference and the correspondence relation.

  • Publication number: 20220303741
    Abstract: A root key (K_iwf) is derived at a network and sent to MTC UE (10). The K_iwf is used for deriving subkeys for protecting communication between MTC UE (10) and MTC-IWF (20). In a case where HSS (30) derives the K_iwf, HSS (30) send to MTC-IWF (20) the K_iwf in a new message (Update Subscriber Information). In a case where MME (40) derives the K_iwf, MME (40) sends the K_iwf through HSS (30) or directly to MTC-IWF (20). MTC-IWF (20) can derive the K_iwf itself. The K_iwf is sent through MME (40) to MTC UE (10) by use of a NAS SMC or Attach Accept message, or sent from MTC-IWF (20) directly to MTC UE (10). In a case where the K_iwf is sent from MME (40), MME (40) receives the K_iwf from HSS (30) in an Authentication Data Response message, or from MTC-IWF (20) directly.
