  • Patent number: 7203514
    Abstract: A method, apparatus and a computer readable record media storing instructions for executing the same method for interfacing among a hybrid type synchronous or asynchronous terminal to a core network in a next generation mobile telecommunications system. The hybrid type synchronous or asynchronous radio network determines the operating type of the core network when the core network has a connection thereto, and sends the determined core network operating type information and information related to the core network to the hybrid type synchronous or asynchronous terminal, thereby allowing the synchronous or asynchronous terminal to smoothly perform a data interfacing operation with the core network.

  • Patent number: 6992999
    Abstract: In a handover from an asynchronous radio network to a synchronous system, long code state information and activation time are transmitted. The method of transmitting long code state information and activation time includes the step of acquiring handover-related information from a neighboring synchronous system by the asynchronous radio network. In the handover, the synchronous system transmit a first message including activation time information and long code state information to the mobile station by the asynchronous radio network and after receiving the activation time information and the long code state information, makes use of the long code state information based on the activation time information by the mobile station.

  • Patent number: 6975608
    Abstract: A method for performing a handoff between an asynchronous base station and a synchronous base station. The method includes the steps of: a) setting at least one common channel between the synchronous base station and a mobile station; b) determining whether there is an asynchronous base station to be handed off in neighbor asynchronous base stations based on monitoring information of the neighbor asynchronous base stations; c) if there is no asynchronous base station, requesting a handoff to the synchronous base station and receiving a compressed mode message through the common channel; d) selecting a synchronous base station to be handed off based on the compressed mode message; and e) performing the handoff from the asynchronous base station to the synchronous base station.

  • Patent number: 6918622
    Abstract: A robot hand finger makes a hooking movement similar to that of the human fingers with less number of driving units by installing a 4-joint link. A robot hand includes several fingers and 4-joint link in order to implement a horizontal movement of the fingers. A robot hand selectively drives a hooking movement and a horizontal movement of fingers with less number of driving units by having a clutch unit. A robot hand includes fingers with a strain gage and is able to control a grasping force by using a value measured by the strain gage.
