  • Publication number: 20130067144
    Abstract: According to one embodiment, a controller for a storage apparatus is disclosed having interfaces connectable to a host system, a first storage apparatus and a second storage apparatus. A data in the first storage apparatus and a data in the second storage apparatus are duplicates. A status table stores the operating state regarding the first storage apparatus and the second storage apparatus, wherein the operating state indicates among writing, reading, or standing by. A monitor monitors the interfaces and set up the operating state into the status table. A buffer memory buffers the data for writing in the first storage apparatus and the second storage apparatus. A command response unit receives the data for writing and write-in request from a host system, and directs the writing of the data to the first storage apparatus and the second storage apparatus while making the buffer memory buffer the received data.

  • Patent number: 8223684
    Abstract: According to this invention, there is provided a method applicable to the system which comprises a plurality of base stations each forming radio zones and storing a mobile terminal, and a gateway being connected to a packet communication network and relaying packet communication between the packet communication network and the mobile terminal. The method comprises buffering packets transmitted by a downlink to the mobile terminal in a packet buffer, requiring retransmission of unarrived packets in handover accompanied by movement among the radio zones, reading the packet required from the mobile terminal to retransmit the packet to the mobile terminal that is a request source, and assigning serial identification numbers to packets at least in a start to an end of the handover. When the identification numbers of the reached packets are discontinuous, the mobile terminal requires retransmission of packets needed to eliminate the discontinuity.

  • Patent number: 8218504
    Abstract: According to one embodiment, a mobile communication system includes base stations each forming a wireless zone for wirelessly accommodating mobile terminals, and a control device accommodating the base stations. The control device includes a construction module, a prediction module and an instruction module. The construction module constructs a database regarding a history of handovers by the mobile terminals. The prediction module predicts a base station of the next connection destination of a mobile terminal being in communication and timing of a handover to the base station of the next connection destination on the basis of the database. The instruction module instructs the handover to the predicted base station to the mobile terminal being in communication before the timing comes.
