Abstract
A wireless end-user device has a configurable wireless wide-area network (WWAN) modem capable of connection to both a home WWAN and a roaming WWAN. One or more processors classify whether an application is interacting with a user in a user interface foreground of the device. At a time when Internet service activities are communicated through the roaming WWAN, the processors use a differential traffic control policy list to determine whether or not to apply a differential traffic control policy to an application requesting Internet service access. When the policy is applicable, and the application is not classified as interacting with a user in the device user interface foreground, the Internet service access request is blocked.
