  • Publication number: 20110170412
    Abstract: Fine grained RAN aware traffic prioritization in spectrum constrained modern wireless networks which support differentiated service plans uses cell load metrics supplied to a Fine grained Traffic flow Prioritization Engine (FTPE) with and without the assistance from a client side collection module, Peer Agent (PA), at the mobile. Knowledge about a mobile's subscription plan is derived from a Subscription Profiles Repository (SPR). Dynamic control on traffic prioritization is applied through operator policy control engines, Policy and Charging Rules Function (PCRF) module. The FTPE works with flexible flow aggregation rules to simplify and scale prioritizing, blocking, and deferring decisions. The FPTE may apply Deep Packet Inspection (DPI) techniques to identify application flows, and uses hierarchical queue disciplines to achieve the necessary flow control. The FPTE may also instead use an adjunct DPI to perform the flow identifications.

  • Patent number: 7945692
    Abstract: The invention increases performance of HTTP over long-latency links by pre-fetching objects concurrently via aggregated and flow-controlled channels. An agent and gateway together assist a Web browser in fetching HTTP contents faster from Internet Web sites over long-latency data links. The gateway and the agent coordinate the fetching of selective embedded objects in such a way that an object is ready and available on a host platform before the resident browser requires it. The seemingly instantaneous availability of objects to a browser enables it to complete processing the object to request the next object without much wait. Without this instantaneous availability of an embedded object, a browser waits for its request and the corresponding response to traverse a long delay link.

  • Publication number: 20110047243
    Abstract: The invention increases performance of a browser over long-latency links by smart pre-fetching of selective objects to increasing the level of concurrency in subsequent operations. A Web browser with a pre-fetch agent can speed up Internet transactions from the browser over long-latency data links. This agent can help determine the order of fetching objects in such a way that an object is ready and available locally before the resident browser requires it. The seemingly instantaneous availability of objects to a browser enables it to complete processing the object to request the next object without much wait. Without this instantaneous availability of an embedded object, a browser waits for its request and the corresponding response to traverse a long delay link.

  • Publication number: 20100302957
    Abstract: A system for optimizing communications on a radio network by altering transitions between different link states that includes several modules. The activity, environment, and load module monitor monitors the link layer based on spectral-load metrics and radio-link metrics. The state transition control module determines when user equipment transitions between different states based on the type of user equipment, user equipment battery life, whether the user equipment is connected to an alternating current outlet, a spectral cost, and a backhaul cost. The channel state influencer module uses any of direct messages, ping messages, and keep-alive messages to influence the link state. The policy and preference handler enables or disables transitions based on the bearer technology type, the type of user equipment, the user's subscription plan, and the load level on the network.
