Abstract: A whittling proxy system can receive a target web page that includes a plurality of Javascript functions and a plurality of objects needed to load the target web page. The system can determine a target Javascript function of the plurality of Javascript functions to be tested for a whittling capability. The system can generate a full version and a partial version of the target web page. The full version includes all of the plurality of Javascript functions. The partial version includes the plurality of Javascript functions excluding the target Javascript function. The system can conduct a test to determine a first page signature associated with the full version and a second page signature associated with the partial version. The system can determine if the first page signature matches the second page signature, and if so, can determine that the target Javascript function can be whittled.

Abstract: Concepts and technologies are disclosed herein for adaptive bit rate mobile video objective testing. A system can receive a plurality of screen-capture frames, where each of the plurality of screen-capture frames corresponds to a respective frame of an adaptive bit rate video stream being displayed on a screen of a test device. The system can create a screen-capture video stream and determine that the screen-capture video stream corresponds to a reference video stream that is non-annotated. The system can obtain a reference video signature package, align the screen-capture video stream with the reference video stream using the reference video signature package, generate full reference video quality performance indicators, and determine delivery quality performance indicators for the screen-capture video stream. The system can join the full reference video quality performance indicators and the delivery quality performance indicators to form an objective quality of experience data structure.

Abstract: Power and resource efficiency of a mobile network device are increased. In one aspect, a tail optimization protocol (TOP) enables cooperation between a mobile device and an associated radio access network to eliminate idle periods (e.g., tails) when possible. Various systems and methods described herein can leverage the ability of applications and/or their associated connections to accurately predict a long tail time, from which a mobile device can notify an associated cellular network on such an imminent tail in order to allow the cellular network to immediately release tail resources. Various other aspects provided herein realize TOP via fast dormancy and/or other similar notification mechanisms, which enable a handset or other device to notify a cellular network for immediate resource release.

Abstract: A method, computer-readable storage device and apparatus for closing a transmission control protocol connection in a wireless network are disclosed. For example, the method sends a first transmission control protocol option requesting a use of a silent transmission control protocol closure for the transmission control protocol connection, receives a confirmation from a recipient device that silent transmission control protocol closure is to be used for the transmission control protocol connection, sends a second transmission control protocol option that indicates a connection timeout period for the sender device, receives a connection timeout period for the recipient device, tracks the connection timeout period for the sender device and the connection timeout period for the recipient device, and closes the transmission control protocol connection when one of the connection timeout period for the sender device or the connection timeout period for the recipient device has expired.

Abstract: Techniques control traffic transmissions to manage radio resource utilization. When content is being streamed to user equipment (UE) and is at least initially intended to be streamed in real time at a constant bitrate, a communication management component can determine whether the content being transmitted to the UE can be delayed, instead of being transmitted in real time. In response to determining that the content can be delayed, the communication management component can facilitate buffering data and periodically streaming the data to the UE in data bursts to reduce use of UE power and radio resources. When transmitting a visual image to a UE, the communication management component can adjust resolution of a visual image to correspond to screen dimensions of the UE based on information indicating screen dimensions of the UE that can be received from the UE.

Abstract: Analyzing mobile device applications within a wireless data network and other related aspects are presented herein. More particularly, described herein is a novel Intelligent Mobility Application Profiling Tool (iMAP) and/or other mechanisms, systems and methods for profiling and benchmarking applications associated with mobile devices in a wireless data network. Various systems and methods described herein expose cross-layer interaction associated with a network device in order to profile an application on the network device with respect to energy efficiency, performance, and functionality. As described herein, radio resource control (RRC) analysis can be performed to infer RRC states associated with a given application, identify tail time, etc. Further, analyzers are employed for various layers, including transmission control protocol (TCP) and/or hypertext transfer protocol (HTTP), as well as to analyze communication bursts associated with a given application. Analysis results are subsequently utilized to deliver application profiling results to a user.

Abstract: Mobile device data transfer via a wireless network is disclosed. A data manager component (DMC) on a carrier-side of an air interface can receive a request for data from a device located on a client-side of the air interface. The DMC can collect data related to the data request. Data can be collected by the DMC from remotely located servers. The collected data can be parsed to facilitate determining additional data that can be collected based on the request for data. The collected data and additional data can be bundled and returned via the air interface to the device on the client-side. Bundling the collected data and additional data can be in accord with an IND scheme, an ONLD scheme, a PARCEL(X) scheme, etc. This can improve load times associate with the requested data and can also reduce power consumption associated with the data transfer over the air interface.
