Device Assisted Services (DAS) for protecting network capacity is provided. In some embodiments, DAS for protecting network capacity includes monitoring a network service usage activity of the communications device in network communication; classifying the network service usage activity for differential network access control for protecting network capacity; and associating the network service usage activity with a network service usage control policy based on a classification of the network service usage activity to facilitate differential network access control for protecting network capacity.

Device-Assisted Services for Protecting Network Capacity

A method for implementing a service policy on a device by obtaining, from a user interface (UI) or a network interface, a quality of service (QoS) activity map of an application identifier to a QoS policy, wherein the QoS policy is determined at least in part by an access state qualifier, the access state qualifier characterizing an aspect of access network resources; identifying a device service usage in association with the application identifier; applying the QoS policy from the QoS activity map to the device service usage, wherein a QoS service activity, including the device service usage, falls within a class of activities associated with the application identifier and governed by the QoS policy; and processing the device service usage in accordance with the QoS policy.

Quality of service for device assisted services

A system configured to detect a requested access to an ambient service over a wireless network, the requested access being associated with a communications device communicatively coupled to the system over the wireless network, the ambient service providing sponsored access to a network destination, wherein the sponsored access comprises a usage of the wireless network associated with the ambient service that is sponsored by a sponsor entity; obtain, based on the requested access, a associated with the communications device or the wireless network; and determine, based on the traffic characteristic, whether the requested access is within an ambient service profile controlling access by the communications device to the ambient service over the wireless network. When the requested access is within the ambient service profile, the system allows the requested access, and when the requested access is not within the ambient service profile, the system prevents the requested access.

Adaptive ambient services

Systems and methods for optimizing a polling interval to capture new or changed content at an application server in a wireless network are disclosed. In one aspect, embodiments of the present disclosure include a method, which may be implemented on a system, for polling the application server using a first polling interval, monitoring responses received from the polling of the application server, adjusting the first polling interval to a second polling interval for polling the application server and/or using the second polling interval for polling another resource delivering same or similar content as the application server.

Optimization of resource polling intervals to satisfy mobile device requests

Systems and methods for aligning data transfer to optimize connections established for transmission over a wireless network are disclosed. In one aspect, embodiments of the present disclosure include a method, which may be implemented on a system, for aligning data transfer to a mobile device to optimize connections made by the mobile device in a cellular network. The method includes batching data received in multiple transactions directed to a mobile device for transmission to the mobile device over the cellular network such that a wireless connection need not be established with the mobile device every time each of the multiple transactions occurs. For example, the data received in the multiple transactions for the mobile device can be sent to the mobile device, in a single transaction over a single instantiation of wireless network connectivity at the mobile device.

Mobile network background traffic data management with optimized polling intervals

An USSD transporting method (200) and mobile computing device (410) are described The method (200) can include the steps of: providing a data pushing operation (210) over a universal supplementary services data (USSD) channel from the application server to the mobile device client; and initiating a data pulling operation (220) over an internet protocol (IP) channel by the mobile device client, in response to the pushing operation Advantageously, for short data transfers, such as application server push notifications, USSD messages require lower power drain than packet data, due to the longer time to transition to an RRC idle state after the data transfer is completed Also, push notifications can be sent over USSD without an open IP session, thereby saving the client from having to maintain a persistent IP session, while employing alternate pulling transport means such as wireless LAN which require lower power drain than a wide area network

USSD transport method and device

A method (200) and device (300) for saving energy in a wireless communication device configured to maintain a persistent communication session over a wireless network with an application server. The method (200) can include: opening (210) a persistent communication session with an application server via a cellular network; measuring (220) a round trip time (RTT) from sending a message to the application server to receiving an acknowledgement message from the application server; and automatically transitioning (230) the device from a first operating state to a second operating state after an amount of time in the absence of subsequent data traffic exceeding a predetermined threshold, wherein power consumption associated with the second operating state is less than power consumption associated with the first operating state, and the predetermined threshold is a function of the measured round trip time. Advantageously, the method (200) can measure the actual RTT and transition to a low power based on the measured RTT exceeding a predetermined threshold, before the expiration of a network configured inactivity timer and in the absence of subsequent data traffic, which helps to minimize unnecessary power drain in a wireless communication device and minimizes inefficiencies in connection with data exchanges between a network and a wireless communication device.

Method and device with dynamic dormancy

A method, system, and computer program product for generating a high dynamic range (HDR) image from a plurality of frames simultaneously captured by cameras of a portable device. The method includes detecting, by a main camera of the portable device, a current dynamic range level of a current scene. In response to detecting the current dynamic range level, a main camera exposure compensation value is applied to the main camera and an auxiliary camera exposure compensation value, which is different from the main camera exposure compensation value, is applied to at least one auxiliary camera. The method further includes simultaneously capturing a first frame by the main camera and at least one second frame by at least one auxiliary camera. The method further includes combining the first frame and the at least one second frame to create the HDR image.

Multi-camera capture of a high dynamic range image

A method, system, and computer program product for an image capturing device having at least two cameras to obtain a focus point of a current scene. The method includes in response to performing a focus procedure via at least one camera of the image capturing device, determining whether a focus point has been found. The method further includes, in response to determining the focus point has not been found: (1) adjusting a number of focus scan steps of an auxiliary focus procedure utilized by only the at least one auxiliary camera and (2) performing the auxiliary focus procedure using the adjusted number of focus scan steps. The method further includes determining whether the focus point has been found, and in response to determining the focus point has been found, automatically synchronizing, to a main lens of the main camera, a current position of the lens of the at least one auxiliary camera.
