Abstract
A method is provided for connecting an in-vehicle communication system to a plurality of wireless communication networks, including a mobile telephony network and an internet protocol network. The in-vehicle communication system is configured to roam between the plurality of wireless communication networks, wherein the method includes the step of receiving a first wireless communication signal from one of the plurality of wireless communication networks. The method also includes the step of detecting a second wireless communication signal from a second of the plurality of wireless communication networks. The method further includes the step of determining an intensity level of the first and second wireless communication signals. The method further includes the step of switching the in-vehicle communication system to one of the plurality of wireless communication networks based on the intensity level of the first and second wireless communication signals.
