  • Data relay device and frame processing method by the same
    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.

  • Radio equipment controller, base transceiver station, and method for relaying data
    Patent number: 8391801
    Abstract: A Radio Equipment Controller connected, via a plurality of transmission paths, to a plurality of pieces of Radio Equipment for performing communication with a mobile station, and also connected to an upper-level device is provided. The Radio Equipment Controller includes a required time measurement portion that measures, for each piece of Radio Equipment, required time for the Radio Equipment and the Radio Equipment Controller to relay data that has a predetermined size and is transmitted and received between the upper-level device and the mobile station, and a relaying portion that relays target data that is data to be transmitted and received between the upper-level device and the mobile station by delaying a time to transmit the target data based on the required time for the Radio Equipment relaying the target data.
