## Abstract

Provided is a traffic pattern adaptive modem (modulator-demodulator) gear control method for an electronic device. The traffic pattern adaptive modem (modulator-demodulator) gear control method includes: when a first criteria is met, on-line collecting a period of input data; executing traffic prediction; whether a second criteria is met to apply the traffic prediction is determined; when the second criteria is met, based on the traffic prediction, a modem gear is adaptively adjusted; and when the second criteria is not met, an algorithm is trained or a period is waited for continuing monitoring whether the second criteria is still met.

## Claims

determining whether a second criteria is met to apply the traffic prediction;
when the second criteria is met, based on the traffic prediction, adaptively adjusting a modem gear; and
when the second criteria is not met, training an algorithm or waiting for a period while continuing to monitor the input data for meeting the second criteria.
