Abstract

A portable-mobile personal security system and method for a vehicle includes establishing a telephone call (407) from a portable radiotelephone (101) through a mobile radiotelephone (109). The telephone call established from the portable radiotelephone (101) is aborted (413) when a sensing device (119) indicates an emergency condition. Then, an emergency telephone call is made to an emergency-call center (415) through the mobile radiotelephone (109). While the emergency telephone call is in progress, a geographic position of the vehicle is transmitted to the emergency-call center (417). Additionally, a display (110) on the portable radiotelephone (101) displays status information about the emergency telephone call.

Claims

1. A portable-mobile radiotelephone personal security method for a vehicle comprising the steps of:

powering-on a portable radiotelephone, and generating a portable-power-on signal responsive thereto;

powering-on a mobile radiotelephone in a hands-free mode responsive to the generated portable-power-on signal;

receiving a telephone number from the portable radiotelephone;

receiving a send-call command code from the portable radiotelephone, then sending an end-call command code from the mobile radiotelephone to the portable radiotelephone and initiating a telephone call from the mobile radiotelephone;

initiating a request for an emergency call;

aborting the initiated call when a sensing device indicates an emergency condition;

intiating an emergency telephone call to an emergency-call center from the mobile radiotelephone in response to the request for an emergency call; and

receiving an end-command code from the portable radiotelephone and terminating the telephone call initiated through the mobile radiotelephone responsive thereto.

2. A portable-mobile radiotelephone personal security method for a vehicle comprising the steps of:

powering-on a portable radiotelephone, and generating a portable-power-on signal responsive thereto;

powering-on a mobile radiotelephone in a hands-free mode responsive to the generated portable-power-on signal;

receiving a telephone number from the portable radiotelephone;

receiving a send-call command code from the portable radiotelephone, then sending an end-call command code from the mobile radiotelephone to the portable radiotelephone and initiating a telephone call from the mobile radiotelephone;

initiating a request for an emergency call;

aborting the initiated telephone call when a sensing device indicates an emergency condition;

initiating an emergency telephone call to an emergency-call center from the mobile radiotelephone in response to the request for an emergency call;

receiving an end-call command code from the emergency call center, and terminating the initiated emergency telephone call responsive thereto; and

powering-off both the mobile radiotelephone and the portable radiotelephone after displaying the end-call status on the portable radiotelephone.

3. A method in accordance with claim 2 further comprising a step of:

transmitting a position of the vehicle to the emergency-call center.

4. A method in accordance with claim 3 further comprising a step of:

displaying status information about the emergency telephone call on a display on the portable radiotelephone.

5. A portable-mobile radiotelephone personal security method for a vehicle comprising the steps of:

powering-on a portable radiotelephone, and generating a portable-power-on signal responsive thereto;

powering-on a mobile radiotelephone in a hands-free mode responsive to the generated portable-power-on signal;

receiving a telephone number from the portable radiotelephone;

receiving a send-call command code from the portable radiotelephone, then sending an end-call command code from the mobile radiotelephone to the portable radiotelephone and initiating a telephone call from the mobile radiotelephone in response to receiving a send-call command code;

detecting an off-cradle status of the portable radiotelephone and switching the mobile radiotelephone from hands-free mode to a handset mode;

receiving an end-command code from the portable radiotelephone and terminating the telephone call initiated through the mobile radiotelephone responsive thereto; and

displaying an end-call status on a display of the portable radiotelephone in response to receipt of the end-command code; and

powering-off both the mobile radiotelephone and the portable radiotelephone after displaying the end-call status on the portable radiotelephone.
