Abstract
A communications system having an ATM transmission line and an IP transmission line is disclosed that includes a base station capable of communicating with a mobile terminal through a radio link; and a radio network controller capable of communicating with the base station through the ATM or IP transmission line. The radio network controller includes a division part dividing transmission data into signals of a predetermined data size; a transmission part transmitting the divided signals to the base station at predetermined time intervals; a retransmission part retransmitting the signals transmitted to the base station when a response signal from the mobile terminal is not received within a predetermined period; a measuring part measuring a signal response period in a communications channel between the radio network controller and the mobile terminal through the base station; and a determination part determining the predetermined data size based on the measured response period.
