摘要： A system and method for handing off from a first network to a second network. A determination may be made as to whether an accessible base station of the second network is located in the vicinity of a user equipment based on information on a current location of the user equipment in the first network. An activation message may be generated with a first telephone number as a caller number when an accessible base station of the second network is located in the vicinity of the user equipment based on the determination result. The activation message indicates an initiation of a search for an accessible base station of the second network, and an accessible base station of the second network may be searched for when the activation message with the first telephone number is received. A handoff from the first network to the second network may then be executed when the accessible base station of the second network is located.

摘要： Disclosed are a mobile robot and a controlling method thereof. The mobile robot comprises: a case; and a sensor unit having two or more sending portions and two or more receiving portions arranged on an outer surface of the case separately and alternately. The plurality of sending portions and receiving portions are arranged in an alternating manner, thereby having a directivity. Also, since signals received through the receiving portions are judged based on a reference value, an area unallowable to be detected for an obstacle sensing is minimized, which allows an obstacle to be detected more accurately. When the obstacle corresponds to a side wall on the basis of a moving path of the mobile robot, a distance between the side wall and the mobile robot is calculated based on signals received by the receiving portion closest to the side wall. Accordingly, the mobile robot can move with maintaining a constant distance from the side wall.
