Machine to machine communication system and method using social network service, and machine to machine communication server thereof

The present invention relates to a machine-to-machine communication system using a social network service (SNS), a machine-to-machine communication method, and a machine-to-machine communication server, wherein when the machine-to-machine communication server receives a control information from a second machine-to-machine communication device which has received the control information of a first machine-to-machine communication device through an SNS interface, the machine-to-machine communication server converts the control information into a command recognizable by the first machine-to-machine communication device and transmits the command to the first machine-to-machine communication server such that the second machine-to-machine communication device can receive information corresponding to the command, thereby enabling a user, which is a person, to communicate with a machine-to-machine communication device using an interface of an SNS familiar to the user and to easily control the machine-to-machine communication device or acquire information.
