Managing wireless voice and data communications
First Claim
1. A method of controlling wireless voice and data communications, comprising the steps of:
- (a) identifying a radio access technology (RAT) in use at a vehicle telematics unit;
(b) establishing a wireless connection between the vehicle telematics unit and a central facility;
(c) wirelessly transmitting the identity of the RAT from the vehicle telematics unit to the central facility;
(d) receiving a message at the vehicle telematics unit from the central facility based on the identity of the RAT causing the vehicle telematics unit to;
(d1) carry out simultaneous voice and data communications over a single wireless connection with the central facility when the identified RAT supports simultaneous voice and data communications; and
(d2) establish a voice call with the central facility and receive data via short message service (SMS) messages when the identified RAT does not support simultaneous voice and data communications.

Abstract
A method of controlling wireless voice and data communications includes identifying a radio access technology (RAT) in use at a vehicle telematics unit; establishing a wireless connection between the vehicle telematics unit and a central facility; wirelessly transmitting the identity of the RAT from the vehicle telematics unit to the central facility; receiving a message at the vehicle telematics unit from the central facility based on the identity of the RAT causing the vehicle telematics unit to: carry out simultaneous voice and data communications over a single wireless connection with the central facility when the identified RAT supports simultaneous voice and data communications; and establish a voice call with the central facility and receive data via short message service (SMS) messages when the identified RAT does not support simultaneous voice and data communications.

8. A method of controlling wireless voice and data communications, comprising the steps of:
-
(a) receiving at a central facility the identity of a radio access technology (RAT) in use at a vehicle telematics unit; (b) determining whether the received RAT identity supports simultaneous voice and data communications over a single wireless connection; (c) transmitting a message to the vehicle telematics unit that causes the vehicle telematics unit to; (c1) carry out simultaneous voice and data communications over a single wireless connection when the RAT identity supports simultaneous voice and data communications; (c2) establish a voice call with the central facility and receive data communications via short message service (SMS) messages when the identified RAT does not support simultaneous voice and data communications. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A method of controlling wireless voice and data communications, comprising the steps of:
-
(a) wirelessly receiving at a central facility the identity of a radio access technology (RAT) in use at a vehicle telematics unit and a vehicle location; (b) searching a database that includes a plurality of geographic locations and RATs available at each of the geographic locations for the vehicle location; (c) determining, when the received vehicle location matches a geographic location in the database, that the RAT available at the matched geographic location is the same as the received identity of the RAT in use at the vehicle telematics unit; and (d) transmitting a message to a vehicle owner when the RAT available at the matched geographic location does not match the identity of the RAT in use at the vehicle telematics unit. - View Dependent Claims (17, 18, 19, 20)
