Abstract
A wireless user terminal operates in a mode that is selected based on an indication of the orientation of the wireless user terminal from a gravitational sensor in the wireless user terminal. When the wireless user terminal is in a first orientation, the wireless user terminal operates in a speakerphone mode. When the wireless user terminal is in a second orientation, the wireless user terminal operates in a handset mode. The mode of operation of the wireless user terminal transitions based on movement of the wireless user terminal from the first orientation to the second orientation. For example, when the wireless user terminal placed in a horizontal orientation, one of the speakerphone modes is selected. When the user picks up the wireless user terminal, the wireless user terminal transitions to handset mode. In a personal speakerphone mode, the volume to a handset speaker in the wireless user terminal is increased so that a call may be carried on without holding the wireless user terminal near the user'"'"'s ear and mouth. In a conference speakerphone mode, the wireless user terminal transmits/receives audio signals to/from an external speaker and external microphone.
