Title: SCEF ENTITY, CONTROL DEVICE, COMMUNICATION METHOD, AND NON-TRANSITORY COMPUTER-READABLE MEDIUM
Abstract:
The purpose of the present invention is to provide a SCEF entity which makes it possible to reduce the number of messages between a control device, such as a MME, and a SCEF. The SCEF entity (10) according to the present invention is provided with: a storage unit (11) in which non-IP data that has not been delivered to a communication terminal (40) via a control device (20) is buffered; and a control unit (12) which, upon reception of a control message transmitted from the control device (20) in accordance with a communication event that occurred in the communication terminal (40), transmits the non-IP data buffered in the storage unit (11) to the control device (20) without waiting for the transmission from the control device (20) of an instruction message explicitly indicating a state enabling the delivery of non-IP data to the communication terminal (40).
