Abstract: Energy consumption of cellular interfaces on multihomed mobile devices, such as smartphones, tablets and laptops can be improved by adjusting the inactivity timer of the cellular interface of the mobile devices based on the on/off status of non-cellular interface(s) on the mobile devices. Possible near-future data packets can be transmitted or received on the non-cellular interfaces that co-exist on the mobile devices and thus the inactivity timer of the cellular interface may be dynamically and more efficiently adjusted, based on the on/off status of non-cellular interface(s). If the non-cellular interface is available on the mobile device, then the inactivity timer can be set to be shorter than if only the cellular interface is available.

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: A more efficient network can be achieved by using a cost-benefit analysis determined by mobile device, wireless network, and server device functionality. The cost-benefit analysis can be used to determine whether SPTCP or MPTCP or any combination of the two is used. The mobile device can generate the cost-benefit analysis based on known and unknown device and network metrics and send the cost-benefit analysis to the server device. The server device can then comply with the cost-benefit analysis and then send requested web site data via SPTCP and/or MPTCP in accordance with the cost-benefit analysis.

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.
