Abstract: A method executed by a mobile communication device is provided. The method includes at least the following steps: connecting to a non-cellular network for communicating data traffic in a first channel; determining an idle timeslot ratio of the first channel used by the non-cellular network in a first period of time; and in response to the idle timeslot ratio in the first period of time being lower than a first threshold, switching the data traffic communication from the non-cellular network to a cellular network or another non-cellular network, or switching the data traffic communication from the first channel to a second channel used by the non-cellular network, or providing a notification to a user of the mobile communication device.
