ABSTRACT:
The cellular mobile telephone and system is provided wherein the cellular telephone automatically dials one or more prescribed emergency telephone numbers in the event of an emergency. Automatic dialing of an emergency telephone number is initiated by the user pressing a dedicated push button on the cellular telephone handset, or alternatively, upon the occurrence of an accident which is detected by the cellular telephone. After the cellular telephone dials the predetermined emergency number, the cellular telephone plays a recorded message which indicates that an emergency has occurred and that the telephone user is in distress. Alteratively, the cellular telephone user is allowed to participate in the emergency call upon receiving notification that the cellular telephone has successfully completed the automatic dialing and a connection has been established.
