ABSTRACT:
A mobile terminal is connected to both first and second base station devices when handover is performed. Each of the first and second base station devices is connected to an upper level device. The first base station device is authorized to request retransmission of data to the mobile terminal when there is a bit error in an up-link for transmitting data from the mobile terminal to the first base station device. When a bit error is detected in the up-link from the mobile terminal to the first base station device, and no bit error is detected in the up-link from the mobile terminal to the second base station device, the first base station device does not perform retransmission control, and the second base station device transfers the received data to the upper level device.
