METHOD OF ESTABLISHING A DATA CONNECTION WITH A TELEMATICS-EQUIPPED VEHICLE
First Claim
1. A method of obtaining a network address for a telematics-equipped vehicle, the method comprising the steps of:
- (a) receiving a network address update message from a wireless carrier system that includes at least one network address and associated vehicle identifier;
(b) saving the at least one network address and associated vehicle identifier to a network address server;
(c) receiving a network address request message that includes at least one provided vehicle identifier;
(d) searching the network address server for an associated vehicle identifier that matches the provided vehicle identifier, and if such an associated vehicle identifier is found then obtaining the corresponding network address from the network address server; and
(e) sending a network address response message that is at least partially based on the results of the search in step (d).

Abstract
A method for establishing a wireless, mobile-terminated data connection with a telematics-equipped vehicle so that data can be sent to and received from the vehicle. Generally, the method involves receiving network address update information from a wireless carrier system, using the network address update information to determine if a network address currently exists for a particular telematics-equipped vehicle, and using the current network address (if one exists) to establish a wireless, mobile-terminated data connection with the telematics-equipped vehicle. This method addresses some of the challenges involved in creating a mobile-terminated data connection with a device that has a temporary or dynamic network address.

12. A method of establishing a mobile-terminated data connection with a telematics-equipped vehicle in a dormant mode, the method comprising the steps of:
-
(a) providing a vehicle identifier that identifies the telematics-equipped vehicle with which the mobile-terminated data connection is desired; (b) sending a network address request message from a first system component to a second system component, wherein the network address request message includes the provided vehicle identifier; (c) searching the second system component for a data entry that matches the provided vehicle identifier, and obtaining a corresponding network address if such a match is found; (d) sending a network address response message from the second network component that includes the corresponding network address; and (e) using the corresponding network address to initiate a mobile-terminated data connection with the telematics-equipped vehicle over a wireless network. - View Dependent Claims (13, 14, 15, 16)

17. A method of establishing a mobile-terminated data connection with a telematics-equipped vehicle in an idle mode, the method comprising the steps of:
-
(a) providing a vehicle identifier that identifies the telematics-equipped vehicle with which the mobile-terminated data connection is desired; (b) sending a network address request message from a first system component to a second system component, wherein the network address request message includes the provided vehicle identifier; (c) searching the second system component for a data entry that matches the provided vehicle identifier, and determining if such a match currently exists; (d) if such a match does not currently exist, then sending a network address response message from the second system component to a wireless network that includes the provided vehicle identifier; and (e) causing the wireless network to use the provided vehicle identifier to initiate a mobile-terminated data connection with the telematics-equipped vehicle over a wireless network. - View Dependent Claims (18, 19, 20)
