  • Patent number: 7499436
    Abstract: A mobile communication system includes a mobile communication network connected to a core network (CN) and a plurality of radio network nodes included in the mobile communication network (RAN). Network resources for a data flow between a data transmission node and a data reception node that passes through the CN and RAN are reserved on the basis of RSVP. A region for refreshing a reservation state of network resources concerning the flow is divided into a CN side and an RAN side by taking a predetermined radio network node through which the flow passes as a boundary. Refreshment on the RAN side is conducted with a frequency higher than that of refreshment on the CN side.

  • Publication number: 20090046689
    Abstract: A mobile communication system includes a radio network control apparatus having inside a function block for processing a downlink shared channel and table means for storing various setting information related to the downlink shared channel communication and the downlink shared channel multi-cast communication. According to the information, a multi-cast communication (including uni-cast communication) is realized by using the downlink shared channel for one or more mobile apparatuses. Moreover, a base station has a function to transmit the downlink shared channel data and signaling data received from a radio network control apparatus, to a mobile apparatus via a radio line. Furthermore, it is possible to multi-cast data selectively to a particular mobile apparatus being call-connected.

  • Publication number: 20090025160
    Abstract: After a liquid sample is dropped onto a sample-holding platform 11, a window plate 22 is moved closer to the sample-holding platform 11 to hold the liquid sample between them. Measurement light is delivered onto the liquid sample, and the light transmitted through the sample is measured. After the measurement is completed, a window plate holder 23 is raised, and a hear 14 is moved from a standby position into the gap between the window plate 22 and the sample-holding platform 11. Then, the window plate holder 23 is lowered so as to press the window plate 22 onto the head 14 until the head 14 touches the sample-holding platform 11 below. From this state, the head 14 is swung back to the original position, whereby a wipe material 40 fitted on the head 14 simultaneously wipes off the liquid sample from both the lower surface of the window plate 22 and the upper surface of the sample-holding platform 11.

  • Publication number: 20080317046
    Abstract: The present invention discloses a communication node including a communicating part connected to one or more communication ports, a deriving part configured to derive route candidates for transmitting a packet to a destination node with a connectionless oriented method, and a selecting part configured to select one of the communication ports to be used for transmitting the packet. The deriving part includes a user designation logic part configured to derive one or more of the route candidates with a logic designated by a user, a connection data processing part configured to select one or more of the route candidates based on connection data of each route, and a part configured to exclude at least a route passing a destination port having an unknown medium access control (MAC) address from the route candidates. The packet is transmitted from a communication port corresponding to the route that has not been excluded.

  • Publication number: 20080101295
    Abstract: A packet transferring/transmitting method is provided for use in a mobile communication system 50. In this packet transferring/transmitting method, an upper node 1 determines the implementation of handover (determination step), and a handover addressing node 2 transfers, of a plurality of packets, a non-transmitted residual packet to a handover addressed node 3, and the upper node 1 transmits a new packet to the handover addressed node 3 (transfer/transmission step). This enables maintaining the number of users to be accommodated while securing a wide bandwidth, sharing a line with high efficiency at soft handover, avoiding data residual in the case of the employment of variable communication rate, and preventing an increase in retransmission.
