Patent number: 10820324Abstract: Collecting state information about the resources of radio access networks (RANs) and the Access Point Names (APNs) enables this information to be provided to mobile stations which employ this information to determine which radio access technology (RAT) to employ for connecting to the wireless access network, and to determine which APN to use. This decision is made relative to each application that the mobile station is executing, and these decisions are, optionally, revisited periodically, or as significant changes in the state information are recognized.Type: GrantFiled: October 31, 2018Date of Patent: October 27, 2020Assignees: AT&T INTELLECTUAL PROPERTY I, L.P., VENTURI WIRELESS, INC., APPLE INC.Inventors: Mostafa Tofighbakhsh, Vivek Gupta, Krishna Ramadas

Patent number: 9674729Abstract: A bandwidth estimation algorithm on shared links detects peaks and/or average per-user bandwidth. Estimating is performed at the transport or IP layer with no assistance from lower layer (PHY, MAC, etc.) and the techniques can be used for any of adjusting the level of video optimization to the available bandwidth; driving QoS decisions at the transmitter based on available bandwidth; improving QoS enforcement during transitions among hybrid technologies on a wireless links; and correcting estimates on devices delivering bursty payload.Type: GrantFiled: January 9, 2015Date of Patent: June 6, 2017Assignee: Venturi Wireless, Inc.Inventors: Kanapathipillai Ketheesan, David Choi

Patent number: 9338674Abstract: 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.Type: GrantFiled: December 11, 2014Date of Patent: May 10, 2016Assignee: Venturi Wireless, Inc.Inventors: Kanapathipillai Ketheesan, Krishna Ramadas, Chico Jayanathan, David Choi

Patent number: 8296353Abstract: Flow control is applied to increasing the performance of a browser while pre-fetching Web objects while operating over bandwidth constrained links to increase the level of concurrency, thus reducing contention for limited bandwidth resources with increased levels of concurrency. Using an agent or a gateway to speed up its Internet transactions over bandwidth constrained connections to source servers. Assisting a browser in the fetching of objects in such a way that an object is ready and available locally before the browser requires it, without suffering congestion on any bandwidth constrained link. Providing seemingly instantaneous availability of objects to a browser enabling it to complete processing the object to request the next object without much wait.Type: GrantFiled: December 16, 2011Date of Patent: October 23, 2012Assignee: Venturi Wireless, Inc.Inventor: Krishna Ramadas

Patent number: 8010693Abstract: 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.Type: GrantFiled: November 5, 2010Date of Patent: August 30, 2011Assignee: Venturi Wireless, Inc.Inventor: Krishna Ramadas
