Abstract

A telematic service procedure includes first establishing a connection with a voice call a service center, and then determining whether a digital or analog network status is to be used during the establishment of a connection.

Claims

1. A telematic service procedure comprising:

establishing a connection with a voice call a service center; and

determining whether a digital or analog network status is to be used during the establishment of a connection.

2. The telematic service procedure of claim 1, comprising:

determining available network conditions and determining how to transmit voice and/or data under the network conditions

3. The telematic service procedure of claim 1, comprising classifying available network standards.

4. The telematic service procedure of claim 3, comprising determining transmission protocols available for each classification of available network standards.

5. The telematic service procedure of claim 3, wherein the available network standards include a digital network with available data service, a digital network without data service, and an analog network.

6. The telematic service procedure of claim 5, further comprising, when a digital network status is determined, first using a telematic protocol sequence for a digital network with available data service.

7. The telematic service procedure of claim 6, further comprising making an inquiry to the digital network concerning network standards.

8. The telematic service procedure of claim 7, further comprising analyzing response from the digital network to the inquiry, and detecting whether data service is available.

9. The telematic service procedure of claim 8, further comprising, in the case of a digital network with available data service, implementing standard transmission according to the Global Automotive Telematics Standard protocol.

10. The telematic service procedure of claim 8, further comprising, in the case of a digital network without data service, after expiration of a timer on the service center side, making a data transmission request from the service center by way of a voice channel, wherein the timer is started at the service center with reception of the voice call.

11. The telematic service procedure of claim 8, further comprising, in the case of an analog network status, starting transmission to the service center via modem connection using telematic protocol MEMS.
