1. A method for a mobile terminal to roam between a first network and a second network comprising the steps of:
establishing a first network connection between a first network driver of said mobile terminal and said first network, wherein the first network comprises an internal network; detecting that a signal strength for the first network connection is below a threshold; establishing, based on the detected signal strength being below the threshold, a second network connection between second network driver of said mobile terminal and said second network, wherein the second network comprises an external network; and transitioning communications from said first network to said second network.
