  • Publication number: 20100158029
    Abstract: A method of operating an Internet protocol (IP) address allocates, creates, and processes an interface identifier (ID) of an IP address area. In the allocation, the IP address area includes a subnet prefix area and an Interface ID area, and certain bits of the Interface ID area are used as an index area of a subnet gateway. The allocation is implemented in order from the higher layer to the lower layer so that the Interface ID area is sequentially allocated from the higher bits for the index areas of the respective layers. The combination of the certain bits of the allocated Interface ID and the subnet prefix area of the IP address area is used as the subnet ID of the subnet layers. The lowest subnet gateway allocates the Interface ID to terminating equipment to access the IP network based on a format of the IP address.

  • Patent number: 7693163
    Abstract: A method of operating an Internet protocol (IP) address that effectively allocates, creates, and processes an interface identifier (ID) of an IP address area, and a subnet system using the same are provided. Allocation is done such that in the IP address area including a subnet prefix area and an Interface ID area, certain bits of the Interface ID area are used as an index area of a subnet gateway. In this case, the allocation is implemented in order from the higher layer to the lower layer so that the Interface ID area is sequentially allocated from the higher bits thereof for the index areas of the respective layers. The combination of the certain bits of the allocated Interface ID and the subnet prefix area of the IP address area is used as the subnet ID of the respective subnet layers. The lowest subnet gateway allocates the Interface ID to terminating equipment trying to access to the IP network based on a format of the IP address.

  • Publication number: 20090279510
    Abstract: A system and a method for releasing quality of service (QoS) resources in a mobile communication network enable QoS resources allocated to a mobile terminal to be released, if, after the mobile terminal is allocated with resources for QoS through an Evolution-Data Optimized (EVDO) Revision A (rA) network to receive data serves, the mobile terminal escapes from the EVDO rA network without first performing a resource release request to the EVDO rA network. The system and method may be implemented in the mobile terminal, the access network, the text message server, or any combination thereof, for releasing the allocated QoS resources without requiring the mobile terminal to re-connect to the EVDO rA network.

  • Publication number: 20080083698
    Abstract: The present invention relates to a method for forming fine wiring comprising: preparing a substrate for a printed circuit board; forming a metal thin sacrificial layer on the substrate using a first metal ink; forming a wiring on the metal thin sacrificial layer by inkjet printing using a second metal ink; and removing a portion of the metal thin sacrificial layer to form a wiring pattern. The method for forming fine wiring according to the invention can improve adhesiveness by using metal thin sacrificial layer and prevent spreading of ink in forming fine wiring.

  • Patent number: 7268238
    Abstract: The method of producing 4-fluoroethylene carbonate (FEC), in which ethylene carbonate (EC) reacts with a mixture of fluorine and nitrogen gases, includes feeding a mixture gas of fluorine gas and nitrogen gas into a reactor having ethylene carbonate charged therein, so as to react the ethylene carbonate with the mixture gas of the fluorine gas and the nitrogen gas. The mixture gas fed in the reactor is regulated to have a desired bubble size while passing through a gas bubble regulating column, in which a packing for a packed column is packed. In the method, EC directly reacts with F2/N2 mixture gas to produce FEC, thus a purification process is simple and it is possible to produce FEC at high conversion efficiency and selectivity.

  • Publication number: 20050089008
    Abstract: A method for performing packet data communication between a mobile station (MS) and a packet data serving node (PDSN) in the next generation mobile communication network. In accordance with the packet data communication method, a traffic channel is set up between the MS and a radio network (RN), and a packet connection is set up between the RN and the PDSN. The MS and the PDSN exchange a data packet by means of an Internet protocol (IP) session without setting up a point-to-point protocol (PPP) layer connection. Therefore, unnecessary bytes of a PPP packet can be removed, and a negotiation process for setting up a PPP layer connection and time delay due to the negotiation process can be removed. An operation of transmitting IP information for the MS that is conventionally performed in the PPP layer connection setup process is performed using a broadcast/multicast Internet protocol (IP) packet, in a packet data service method in the mobile communication network.
