Abstract

A method of identifying telematics calls includes the steps of receiving at a vehicle telematics unit a paging message used to connect a call over a wireless carrier system; determining at the vehicle telematics unit if the paging message used to connect the call includes a Mobile Identification Number (MIN) or a Mobile Equipment Identifier (MEID); and establishing the call and, if the vehicle telematics unit determines that the paging message includes the MEID, entering into a mode in which the vehicle telematics unit uses a modem for receipt and transmission of data

Claims

1. A method of identifying telematics calls, comprising the steps of:

(a) receiving at a vehicle telematics unit a paging message used to connect a call over a wireless carrier system;

(b) determining at the vehicle telematics unit if the paging message used to connect the call includes a Mobile Identification Number (MIN) or a Mobile Equipment Identifier (MEID); and

(c) establishing the call and, if the vehicle telematics unit determines that the paging message includes the MEID, entering into a mode in which the vehicle telematics unit uses a modem for receipt and transmission of data.

2. The method of claim 1, wherein step (c) further comprises establishing the call as a voice channel connection.

3. The method of claim 1, wherein the mode step (c) further comprises using the modem over a voice channel.

4. The method of claim 1, wherein the vehicle telematics unit permits the receipt and transmission of data based on the receipt of the MEID included in the paging message.

5. The method of claim 1, further comprising the steps of determining that the paging message includes a MIN, and placing the vehicle telematics unit in a voice mode.

6. The method of claim 5, further comprising the step of preventing modem data communications for the duration of the call.

7. The method of claim 1, further comprising the step of determining that the paging message includes a MIN;

determining an amount of prepaid cellular minutes associated with the vehicle telematics unit; and

allowing or denying voice calling based on the amount of prepaid cellular minutes.

8. The method of claim 1, wherein the call is placed by a call center and the MEID in the paging message is associated with the call center and stored at the wireless carrier system.

9. A method of identifying telematics calls, comprising the steps of:

(a) receiving a call placed to a vehicle telematics unit;

(b) determining that the call originated from a call center based on a trunk group associated with the call; and

(c) paging the vehicle telematics unit using a Mobile Equipment Identifier (MEID) associated with the vehicle telematics unit in response to the determination.

10. The method of claim 9, wherein the call is established as a voice channel connection.

11. The method of claim 9, further comprising the step of communicating data between the call center and the vehicle telematics unit after the vehicle telematics unit receives a paging message that includes the MEID.

12. The method of claim 11, further comprising communicating the data over a voice channel.

13. The method of claim 9, wherein the MEID is associated with the call center and stored at the wireless carrier system.

14. A method of identifying telematics calls, comprising the steps of:

(a) linking the identity of a call center with the Mobile Equipment Identifier (MEID) of a vehicle telematics unit;

(b) storing the linked identity at a wireless carrier system;

(c) receiving a request to place a call at the wireless carrier system from the call center to the vehicle telematics unit;

(d) detecting the identity of the call center based on the received call;

(e) accessing the MEID of the vehicle telematics unit linked with the identity of the call center;

(f) paging the vehicle telematics unit with a page that includes the accessed MEID; and

(g) establishing the call and allowing the receipt of data at the vehicle telematics unit based on the receipt of the page that includes the accessed MEID.

15. The method of claim 14, wherein the call is established as a voice channel connection.

16. The method of claim 14, wherein allowing the receipt of data further comprises using a modem over a voice channel.
