Abstract: An AMI management method, and an AMI management server and a recording medium applying the same are provided. According to the AMI management method, the AMI management server managing an AMI stores customer information including a customer ID and information regarding a meter corresponding to a corresponding customer, requests an AMI platform to generate a service, maps AMI platform information received from the AMI platform as a response to the request onto the customer information, and transmits mapping information including the mapped information to the AMI platform. Accordingly, remote metering can be performed by using IoT communications of various telecommunications operators by using the AMI platform.

Abstract: An IoT network management method and an IoT network server and a terminal applying the same are provided. According to the IoT network management method, when a network joining request is received from the terminal, the IoT network server determines whether to allow the corresponding terminal to join, and, when an environment configuration request is received from the terminal, the IoT network server transmits environment configuration information which is information regarding a communication environment of the corresponding terminal. Accordingly, the terminal and the IoT network server can efficiently manage a network while following the LoRaWAN standards, and also, can change a network path to an effective network path when the surrounding network environment changes or a gateway breaks down, and can achieve stable data transmission by minimizing a data collision between large-scale facilities within a predetermined distance.
