  • Publication number: 20180124645
    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: 8687651
    Abstract: A method and apparatus for interfacing a synchronous core network with an asynchronous radio network in a next-generation mobile telecommunications system is disclosed. The method includes: a) selecting a function necessary to map a synchronous message to an asynchronous message; b) determining whether the synchronous message is to be transmitted to the mobile station or not; c) storing information necessary to map the synchronous message to the asynchronous message if the synchronous message is to transmitted to the mobile station, d) mapping parameters in the synchronous message to those in the asynchronous message, thereby generating the asynchronous message; e) discarding the message not to be transmitted to the mobile station after storing parameters included in the message not to be transmitted onto a predetermined device; and f) transmitting the asynchronous message to the radio resource controller.

  • Patent number: 8220727
    Abstract: The present invention provides a pressure-compensation drip tape, which is used in drip irrigation to continuously and evenly supply a small amount of water to plants. The drip tape of the present invention includes an outer shell 10, and overlapping sheets 21, 23 and 25, which are expandable depending on an increase of water pressure. Furthermore, the drip tape has a main passage 11, which is defined by the outer shell and the innermost overlapping sheet, such that most water supplied from a water source flows through the main passage, pressure-reducing passages 31 and 33, which are defined between the overlapping sheets, and discharge holes 21H, 23H and 25H, which are formed in the border between the main passage and one of the pressure-reducing passages and the border between the pressure-reducing passages, such that the water sequentially flows via the main passage and the pressure-reducing passages and drips outside the drip tape.
