Abstract:
1. A data relay device for relaying data transmitted between a base station device that performs radio communication with a mobile terminal and a plurality of base station control devices that controls the base station device, the data relay device comprising: 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 receiving unit that receives frames from the plurality of base station control devices, each frame independently produced by each of the plurality of base station control devices and the plurality of base station control devices are not synchronized; a frame value detecting unit that detects a predetermined frame value from received frames; and a frame transmitting unit that, when the predetermined frame value is detected, counts up an elapsed time from the detection, and transmits a frame having the same frame value as the detected frame value to the base station control device which transmits the frame of the detected predetermined frame value when the elapsed time from detection reaches the sum of a relay processing time of a data transmitted from the base station device to the base station control device in the data relay device, a relay processing time of a data transmitted from the base station control device to the base station device in the data relay, and the data transmission time.
