Abstract: A method for providing an IoT device with a communication service for accessing an IP network using equipment included in communication infrastructure is provided. The method includes receiving a session generation request including a subscriber identifier, transmitting, to a first instance and a second instance included in the equipment, a first provisioning call for generating a GTP-U session between the first instance and the second instance, receiving, from the first instance or the second instance, a transmission source address, transmitting, to the first instance, a second provisioning call including the transmission source address and a first credential for generating a VPN session between the IoT device and the first instance, and transmitting connection information to the IoT device, the connection information including the transmission source address and a destination address of the first instance.

Abstract: A connection management apparatus of a relay system specifies, when terminal identification information for identifying a target terminal is acquired from a client terminal, a first relay apparatus that relays communication, and specifies connecting information for the client terminal to connect to the first relay apparatus. The connection management apparatus stores the specified connecting information and the terminal identification information in a storage in association with each other, and notifies the client terminal of the specified connecting information. When the specified first relay apparatus receives access based on the connecting information from the client terminal, the specified first relay apparatus relays the communication between the client terminal and the target terminal on the basis of the terminal identification information associated with the connecting information.
