Abstract: A Machine Type Communication Inter Working Function (MTC-IWF) entity (1) includes a trigger controller (11) and a notification service controller (12). The trigger controller (11) controls a device trigger of an MTC device (3) requested from an SCS entity (2). The notification service controller (12) is configured to send, to the SCS entity (2), a subscription request for a notification service including providing a PLMN (5) with management information which is collected outside (4) the PLMN (5) regarding the MTC device (3), and receive, from the SCS entity, a message containing the management information (2) when the subscription request has been accepted. Accordingly, it is possible to contribute to, for example, improvement in collaborative and cooperative operations between the PLMN and an M2M service layer.

Abstract: A communication system according to the present invention includes an application server (10) and a relay apparatus (20) that relays a communication between the application server (10) and a communication network (40). The application server (10) comprises a communication unit (11) that transmits to the relay apparatus (20) a first message in which a first identifier has been set as a destination, the first identifier identifying a communication terminal (30) that performs communication via the communication network (40). The relay apparatus (20) includes a converter (21) that converts the first identifier into a second identifier that uniquely identifies the communication terminal (30) in the communication network (40), and a communication unit (22) that transmits a second message in which the second identifier has been set as a destination to the communication terminal (30) via the communication network (40).
