  • Publication number: 20120324041
    Abstract: Techniques for increasing power and resource efficiency of a mobile device are presented herein. In the mobile device, with regard to periodic or one-time data transfers, a communication management component can analyze information comprising data transfer parameter information, including jitter information, associated with each application of a subset of applications used by the device and can desirably schedule and/or bundle data transfers associated with the applications to reduce the number of separate data bursts to transfer that data to thereby reduce use of wireless resources and power consumption by the device. A push notification system can receive respective jitter information associated with each application from the mobile device, and the push notification system can desirably schedule and/or bundle push notifications to reduce the number of separate data bursts sent to the device to reduce use of wireless resources and power consumption by the device.

  • Publication number: 20120155319
    Abstract: A method and apparatus for characterizing an infrastructure of a wireless network are disclosed. For example, the method obtains a first data set from a server log, and obtains a second data set from a plurality of wireless endpoint device. The method characterizes a parameter of the infrastructure of the wireless network using the first data set and the second data set and optimizes a network resource of the wireless network based on the parameter.

  • Publication number: 20120151041
    Abstract: Systems and methods for analyzing mobile device applications within a wireless data network 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.

  • Publication number: 20120122405
    Abstract: A method, a computer readable medium and an apparatus for providing a dynamic inactivity timer are disclosed. For example, the method monitors a timer for a time threshold associated with a burst of a plurality of bursts of packets, and determines if the timer for the time threshold associated with the burst has expired. The method predicts an inter-burst time for the burst, if the timer for the time threshold associated with the burst has expired and sets the dynamic inactivity timer in accordance with the inter-burst time for the burst.

  • Publication number: 20120058773
    Abstract: A method, computer readable medium and apparatus for performing a demotion in a cellular communications network are disclosed. For example, the method receives a packet indicating that a batching transfer is completed, determines if a background packet was received after receiving the packet indicating that the batching transfer is completed and demotes a state of a state machine implemented by a radio network controller to a lower state if the background packet was not received.

  • Publication number: 20120057571
    Abstract: A method, computer readable medium and apparatus for normalizing cellular communications network data are disclosed. For example, the method collects a data packet from the cellular communications network, modifies a time stamp of the data packet in accordance with a promotion delay time from the time stamp of the data packet to create a normalized data packet and processes the normalized data packet to optimize state machine configurations.

  • Publication number: 20120052814
    Abstract: Systems and methods for increasing the power and resource efficiency of a mobile network device are presented herein. More particularly, described herein is a novel Tail Optimization Protocol (TOP) and/or other mechanisms, systems and methods for enabling 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.
