Telematic system with multiple network access devices in a multi-network environment

The present invention relates to a computer-implemented method for controlling a terminal system, in particular, an automotive terminal system, connectable to multiple provider networks and comprising multiple network access devices (NADs) and a computer system, comprises the steps of reading information on the physical and/or logical location of the terminal system; reading user configurations and provider service layer agreements; based on the read information, user configurations and provider service layer agreements creating associations between applications to be run on the NADs or the terminal system, the NADs and the multiple provider networks; and based on the created associations and the information on the physical and/or logical location of the terminal system selecting one of the NADs and one of the provider networks for running one of the applications on the selected NAD and connecting the selected NAD with the selected provider network.
