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: A method and a system for authenticating a program are provided. A user system receives a program developed by a developer system and an authentication key, creates an additional authentication key by applying a preset authentication algorithm to the received program, and uses the received program if the received authentication key is matched to the additional authentication key.

Abstract: A method for supporting a global IP telephony system in an NAT-based private network is disclosed. The disclosed method includes: establishing a special channel for exchanging information for address translation with a NAT router and identifying the type of a dynamic NAT mode of the NAT router using the special channel. A private address contained in a signaling message forwarded to a public IP terminal is transmitted to the NAT router using the special channel, according to the type of the dynamic NAT mode. A public address is dynamically assigned for the private address by the NAT router and used to replace the private address in a regenerated signaling message. The regenerated signaling message is then transmitted to the public IP terminal. The public address assigned by the NAT router is released when a call is terminated. Since the information required in each H.
