ABSTRACT:
In a communication system which has a base station, a mobile station and an object device controllable by the mobile station, the mobile station monitors status of the object device to detect whether or not the object device is ready to receive a data signal sequence sent through the mobile station. Such a data signal sequence may be either a voice data signal or an image data signal. The mobile station can transmit, towards the base station, a response determined by the status of the object device. A reception state of the object device may be switched from one to another to selectively receive the voice and the image data signals.
