## Abstract

A wireless end-user device has wireless wide-area network (WWAN) and wireless local-area network (WLAN) modems. A WWAN-specific differential traffic control policy includes aspects that are user-configurable for specific applications, including a background/foreground operation-based policy. One or more processors implement an application program interface that allows an application to access one or more aspects of the policy that are applicable to that application, including one or more user-configurable aspects of the policy.
