Patent ID: 8274984

Claim:
A communications system, comprising: a base station configured to communicate with a mobile terminal through a radio link; and a radio network controller providing, at predetermined time intervals, the base station with original data to be transmitted to the mobile terminal by the base station, wherein the radio network controller includes: a division part configured to divide the original data into a plurality of data portions of a predetermined data size; a provision part configured to provide the base station with a predetermined number of the divided data portions at a time at the predetermined time intervals; a measuring part configured to determine a transmission time of a first signal transmitted by the radio network controller for measuring a signal response period in a communication channel between the radio network controller and the mobile terminal through the base station and a reception time of a second signal transmitted by the mobile terminal in response to the first signal and received by the radio network controller, and to measure the signal response period based on a difference between the determined transmission time and the determined reception time; a determination part configured to determine whether the measured signal response period is greater than a threshold and to determine whether the measured signal response period is greater than a predetermined period in response to determining that the measured signal response period is greater than the threshold; and a changing part configured to increase a number of the divided data portions provided by the provision part to the base station at a time within each of the predetermined time intervals from the predetermined number and change an amount of communication resources allocated to the communication with the mobile terminal based on the increased number of the divided data portions to be provided to the base station at a time within each of the predetermined time intervals, in response to the determination part determining that the signal response period measured by the measuring part being greater than the predetermined period.
