Device-assisted services for protecting network capacity
A wireless end-user device has a wireless wide-area network (WWAN) modem. A network element securely provisions the device with a differential traffic control policy list that distinguishes how network traffic for at least one network type should be treated on a per-application basis. A user is also allowed, through an interface, to configure one or more aspects of how a differential traffic control policy is applied to applications. One or more device agents classify whether an application is interacting with a user in a user interface foreground of the device and whether data communication for Internet service activities is provided through the WWAN modem. Based on the network- and user-configured policy information and the classifications, a network stack agent determines whether to allow or disallow a given Internet access request. Some requests that may otherwise be disallowed are allowed when the WWAN modem is already active to serve another request.
1. A wireless end-user device, comprising:
a wireless wide area network (WWAN) modem to communicate data for Internet service activities between the device and at least one WWAN, when configured for and connected to the WWAN;

a service processor to implement
a policy agent configured to securely receive, from a network element, at least a portion of a differential traffic control policy list, the differential traffic control policy list distinguishing between a first one or more applications capable of execution on the device and a second one or more applications and/or services capable of execution on the device,
an interface to allow a user to configure one or more aspects of the differential traffic control policy for one or more of the first one or more applications,
one or more device agents to classify whether a particular application associated with a first Internet service access request, and capable of both
interacting with a user in a user interface foreground of the device, and
at least some Internet service activities when not interacting with a user in the device user interface foreground,
is interacting with the user in the device user interface foreground, and to classify whether data communication for Internet service activities is provided through the WWAN modem, and
a network stack agent to, based on the classification performed by the one or more device agents and based on whether the particular application is a member of the first one or more applications, disallow the first Internet service access request for the particular application
in a first classification state wherein the request is disallowed based on a match with a disallowed state specified at least in part by a user-configured aspect of the differential traffic control policy, and
in a second classification state comprising data communication for Internet service activities provided through the WWAN modem, the particular application not interacting with the user in the device user interface foreground, and the particular application being one of the first one or more applications,
but to allow the first service access request for the particular application in the second classification state during at least one time period based on the WWAN modem being active to serve a second Internet service access request from a different application and/or service.

7. The wireless end-user device of claim 6 , wherein the one or more device agents to classify whether data communication for Internet service activities is provided through the WWAN modem do so at least in part by classifying a wireless network type providing data communications for Internet service activities from among the plurality of wireless network types, and the policy agent is further configured to select a traffic control policy from the multimode profile based at least in part on the classified wireless network type.
8. The wireless end-user device of claim 7 , wherein the plurality of wireless network types include at least one wireless local area network (WLAN) type as the wireless network type when data communication is provided via a WLAN modem on the device.
9. The wireless end-user device of claim 8 , wherein the policy agent is further configured to, when the classified wireless network type is at least one type of WLAN, select a traffic control policy from the multimode profile based at least in part on a type of network connection from the WLAN to the Internet.
10. The wireless end-user device of claim 6 , wherein the plurality of wireless network types include three or more of 2G WWAN, 3G WWAN, 4G WWAN, home WWAN, roaming WWAN, and WLAN.
11. The wireless end-user device of claim 1 , wherein the one or more device agents to classify whether data communication for Internet service activities is provided through the WWAN modem do so at least in part by classifying a wireless network type providing data communications for Internet service activities from among a plurality of wireless network types supported by the device for data communication.
12. The wireless end-user device of claim 1 , wherein the at least one WWAN comprises a home WWAN and a roaming WWAN, and wherein the second classification state comprises data communication for Internet service activities provided by the roaming WWAN, but not data communication for Internet service activities provided by the home WWAN.
13. The wireless end-user device of claim 1 , the policy agent further configured to query the network element to determine whether a given application capable of execution on the device is included in the differential traffic control policy list.
14. The wireless end-user device of claim 1 , wherein the network stack agent is further to allow the first Internet service access request for the particular application in a third classification state comprising data communication for Internet service activities provided through the WWAN modem, the particular application not interacting with a user in the device user interface foreground, and the particular application is one of the second one or more applications and/or services.
15. The wireless end-user device of claim 1 , wherein the network stack agent is further configured to dynamically change at least one policy application to allow or disallow the first Internet service access request based on a power state of the device.
16. The wireless end-user device of claim 1 , wherein the network stack agent is further configured to dynamically change at least one policy application to allow or disallow the first Internet service access request based on a device usage state.
