  • Publication number: 20150066931
    Abstract: According to one embodiment, an information processing apparatus includes a collection unit, a storage and a retrieval unit. The collection unit collects first metadata from information sources, the first metadata relating to information that has no common standard between the information sources and including first attributes and first attribute values. The storage stores each of the first attributes and first attribute values corresponding to each of the first metadata. The retrieval unit retrieves the first metadata, based on corresponding relations of the first attributes and the first attribute values with second attributes and second attribute values in second metadata newly obtained, to extract corresponding metadata that is one of the first metadata and corresponds to the second metadata.

  • Patent number: 8582494
    Abstract: A data relay device relays data between a base station device and a base station control device. The data relay device includes a data transmission time acquiring unit that acquires a data transmission time from when data is transmitted from the data relay device to when the data is received by the data relay device via the base station device, a frame value detecting unit that detects a predetermined frame value from a frame transmitted from the base station control device and stores the data, and a frame transmitting unit that, when the predetermined frame value is detected, after a predetermined time elapses in addition to the data transmission time acquired by the data transmission time acquiring unit after detection, transmits a frame having the same frame value as the detected one to a transmission source of the frame from which the predetermined frame value is detected.

  • Patent number: 8385816
    Abstract: A relay device that monitors and controls common public radio interface (CPRI) links that are links using CPRIs functioning as interfaces for connecting multiple relay devices included in a radio base station detects a disconnected CPRI link by monitoring, via the CPRI links, relay information containing communication data and control data. The relay device distributes a control content, such as a forced link disconnection that forcibly disconnect a CPRI link or no-transmission that stops the transmission of the communication data, with respect to each CPRI link in accordance with a connecting location of the CPRI link in which a link disconnection is detected. The relay device monitors and controls each CPRI link.
