    Abstract: A controller in a wireless communication device automatically generates and sends presence updates when a detector in the device senses user motion or other parameters related to the user's current activity. The presence updates may indicate that the user is performing the sensed activity. When the detector no longer senses the user motion or other parameters, the controller automatically generates and sends another presence update to indicate that the user is finished performing the activity.
