Wireless end-user device with differentiated network access for background and foreground device applications

摘要

A wireless end-user device has wireless wide-area network (WWAN) and wireless local-area network (WLAN) modems. One or more processors determine when an application is running in a background state or as a foreground application. The processors control application access for Internet service activities through an application program interface (API). At a time when Internet service activities are communicated through the WWAN modem, the processors use a differential traffic control policy to selectively block and allow network access for an application based on the determination as to whether the application is running in a background state or as a foreground application. A different policy may apply to WLAN modem usage.
