A mobile station () that includes a transceiver () that receives an alert request () and a controller (). Responsive to the alert request, the controller can enter the mobile station into an alert active mode in which an alert signal is generated on the mobile station. Responsive to not receiving an acknowledgement to the alert signal within a defined period, the controller can enter the mobile station into an alert sleep mode in which at least one parameter of the alert signal is changed. Further, the controller can awake the mobile station from the alert sleep mode in response to detecting a user presence. The mobile station further can include an accelerometer () and/or a positioning system () that detect the user presence by detecting movement of the mobile station.
