Abstract: A method and an apparatus for communication between an Automatic Configuration Server (ACS) and a Customer Premise Equipment (CPE) over an Internet-based network are provided. A CPE determines in a power standby state whether an inform request message transmission period is received. If the inform request message transmission period is received, the CPE transitions from the power standby state to an active state and transmits an inform request message to an ACS. The CPE receives an inform response message from the ACS in response to the inform request message, and upon receiving the inform response message, transitions from the active state to the power standby state.

Abstract: Featured is a gripper for a tailgate; such a gripper includes a rotation pad at each regulation surface of a locator and a clamper of each clamping unit, where a swivel ball is mounted on the rotation pad. Each clamping unit is movable in a vertical direction or a horizontal direction by a movement unit of a frame so as to be adaptable to angle differences of each regulation surface of the tailgate. Such a tailgate gripper further includes a frame having a tool mounting portion to mount a tool changer of a robot in a lower portion of a rear surface thereof.

Abstract: Featured is a door gripper for a vehicle including a frame, upper clamping units and a lower clamping unit. The lower clamping unit including a rotary pad with a swivel ball in restricted surfaces of a clamper and a locator of a lower clamping unit to deal with an angle difference of restricted cross sections of the door. The lower clamping unit and upper clamping units being configured and arranged so as to be movable in the up-down direction and the width direction along a guide rail of the frame in order to deal with differences in height and width of the restricted cross section.

Abstract: A grip device for moving a front floor of a vehicle includes a front clamping member and a rear clamping member. The front claming member can clamp a flange portion around a suspension mounting hole of the front floor according to an angle of the flange portion. The rear clamping member can claim a member flange portion of the front floor according to the change of clamping position. The device can be applied to various vehicle models.

Abstract: A method and apparatus for upgrading software in a Customer Premise Equipment (CPE) that exchanges Inform messages with a server over an Internet Protocol (IP) network are provided. The software upgrade method includes, upon receiving a download request message from an Automatic Configuration Server (ACS) remotely controlling the CPE, rebooting in an upgrade mode after storing upgrade execution information included in the download request message, acquiring a software image for upgrade from an upgrade server based on the stored upgrade execution information after rebooting in the upgrade mode, updating an old software image with the acquired software image, and rebooting in a normal mode after completing the update of the old software image.

Abstract: In an apparatus and method for managing wireless resources in a wireless local area network (WLAN) system, stations in the same network are allowed to exchange random back-off information with each other, and thus the probability of data transfer collision is reduced. Therefore, it is possible to efficiently use the wireless resources of the WLAN system.

Abstract: A wireless network system includes: a plurality of wireless terminals; and wireless network access equipment for storing a plurality of phone numbers assigned to each of the wireless terminals and dynamically assigning the phone numbers and Internet Protocol (IP) addresses to each of the wireless terminals. The method of registering a phone number of a wireless terminal in a wireless network system includes: storing a plurality of phone numbers determined to be assignable with respect to each of a plurality of wireless terminals; responding to a request from a first wireless terminal gaining new access to the wireless network system and assigning a dynamic IP address to the first wireless terminal; responding to a request from the first wireless terminal and sending network information on the phone number assigned to the first wireless terminal; and registering the phone number as a phone number of the first wireless terminal.
