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.

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.
