<p>A personal safety alarm implemented within a wireless phone (200) emits a loud shrill sound using the phone ringer (258) and simultaneously initiates a connection to a predefined emergency phone number (244) when activated. If the wireless phone (200) is inactive when the user activates the alarm the phone will automatically activate, emit the audible alarm and initiate the emergency call. If the wireless phone (200) is within an established call at the time the user activates the alarm, the wireless phone (200) will activate the audible alarm, disconnect the present phone connection, and initiate the emergency call. The user is provided an indication once the connection to the emergency number is completed. The user is then able to silence the audible alarm with the knowledge that there is a connection to the emergency number. If desired, the user is able to reactivate the audible alarm while the link to the emergency number is active without disconnecting the call.</p> |
