1. A telematics unit for use in a vehicle, comprising:
- a cellular radio transceiver operable for placing an emergency call in a wireless access network;
a location data generating unit operable to determine and output enhanced location information about the vehicle location;
a processor;
a memory; and
an application stored in the memory that, when executed by the processor,builds an emergency call origination message, including at least some of the enhanced location information, wherein the at least some of the enhanced location information comprises an identification of a highway on which the vehicle is travelling,transmits the emergency call origination message via the cellular radio transceiver to a public safety answering point, andperiodically transmits updates of the enhanced location information to the public safety answering point while connected to the public safety answering point in the emergency call.

9. A method of conducting an emergency call, comprising:
-
determining by an enhanced location data engine enhanced location information associated with a vehicle that comprises two or more of a geographical location of the vehicle, a velocity of the vehicle, a heading of the vehicle, and a highway lane identification on which the vehicle is positioned; building an emergency call origination message by a telematics unit in the vehicle, wherein the message comprises the determined enhanced location information and wherein the telematics unit comprises a cellular radio transceiver; transmitting the emergency call origination message by the cellular radio transceiver, wherein after receiving the emergency call origination message at a public safety answering point, the determined enhanced location information is provided to first responders; automatically determining a travel route for the first responders based on the determined enhanced location information; and transmitting the travel route to a communication device associated with the first responders, wherein the communication device is operable to present a map of the travel route. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A method of handling an emergency call, comprising:
-
receiving an emergency call origination message at a public safety answering point, wherein the emergency call origination message is built by a telematics unit that comprises a cellular radio transceiver in a vehicle and comprises enhanced location information determined by an enhanced location data engine associated with the vehicle, and wherein the determined enhanced location information comprises two or more of a geographical location of the vehicle, a velocity of the vehicle, a heading of the vehicle, and a highway lane identification on which the vehicle is positioned; after receiving the emergency call origination message at the public safety answering point, providing the determined enhanced location information to first responders; automatically determining a travel route for the first responders based on the determined enhanced location information; and transmitting the travel route to a communication device associated with the first responders, wherein the communication device is operable to present a map of the travel route.
