System and method of controlling vehicle communications during emergency conditions

A method of controlling vehicle communications, the method comprising:

• determining an emergency condition that hinders wireless communication from a vehicle;
• detecting occurrence of a vehicle event on the vehicle;
• determining a communications priority associated with the vehicle event;
• selectively allowing or blocking wireless communication relating to the vehicle event from the vehicle during the emergency condition based on the communications priority;
• and
• storing information concerning the vehicle event in response to blocking of a wireless communication.

A method of controlling vehicle communications, the method comprising:

• determining an emergency condition that hinders wireless communication from a vehicle;
• providing emergency condition information to the vehicle over a satellite radio broadcast;
• detecting occurrence of a vehicle event on the vehicle, wherein the vehicle event is related to a vehicle condition;
• determining a communications priority associated with the vehicle event;
• and
• selectively allowing or blocking wireless communication relating to the vehicle event from the vehicle over a mobile telephone network during the emergency condition based on the communications priority;
• wherein the step of providing emergency condition information further comprises providing a communications priority value to the vehicle via the satellite radio broadcast.

A method of controlling vehicle communications, comprising the steps of:

• (a) determining occurrence of an emergency condition;
• (b) notifying the vehicle of the emergency condition via a satellite radio broadcast;
• and
• (c) selectively allowing or blocking cellular telephone calls from a telematics unit in the vehicle to a mobile telephone system based on the emergency condition.

A method of controlling vehicle communications, comprising the steps of:

• (a) notifying a vehicle telematics unit of an emergency condition;
• (b) detecting a vehicle event for which information related to the condition of the vehicle is to be reported to the call center via wireless communication from the vehicle telematics unit;
• (c) determining a communications priority associated with the vehicle event;
• and
• (d) selectively allowing or blocking wireless communication from the vehicle telematics unit to the call center to report the information, wherein determination of whether to allow or block the wireless communication is made using the communications priority;
• wherein step (a) further comprises providing a communications priority value to the vehicle telematics unit when notifying it of the emergency condition.
