PURPOSE: A USN(Ubiquitous Sensor Network) system is provided to obtain mobility while connecting a USN sensor with an external communication network. CONSTITUTION: A USN(Ubiquitous Sensor Network) sensor senses information required in a USN. The USN sensor transmits the sensed information by multipoint relay communication. A first communication unit(121) of a USN gateway(120) receives the information of the USN sensor. A second communication unit(124) of the USN gateway transmits the received information to an external communication network. A control unit(126) of the USN gateway controls each unit. An input unit(127) of the USN gateway inputs a command of a user or various settings to the control unit.
