Patent number: 10638499Abstract: To facilitate increasing power and resource efficiency of a mobile device, 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.Type: GrantFiled: April 18, 2019Date of Patent: April 28, 2020Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Alexandre Gerber, Zhuoqing Mao, Feng Qian, Subhabrata Sen, Oliver Spatscheck, Zhaoguang Wang

Patent number: 10244410Abstract: 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.Type: GrantFiled: June 10, 2016Date of Patent: March 26, 2019Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Alexandre Gerber, Zhuoqing Mao, Feng Qian, Subhabrata Sen, Oliver Spatscheck, Zhaoguang Wang

Patent number: 8750109Abstract: A packet trace is received. Inter-arrival times between the multiple packets in the packet trace are determined. An inter-arrival time in the inter-arrival times that is greater than a threshold is identified. An order number of the inter-arrival time is identified. A determination is made as to whether a size of each of at least a portion of the multiple packets is equal to a maximum segment size. When a determination is made that the size of each of at least a portion of the multiple packets is equal to the maximum segment size, a size of the ICW as a product of the order number and the maximum segment size is returned.Type: GrantFiled: August 17, 2012Date of Patent: June 10, 2014Assignees: AT&T Intellectual Property I, L.P., The Regents of the University of MichiganInventors: Alexandre Gerber, Zhuoqing Mao, Feng Qian, Subhabrata Sen, Oliver Spatscheck, Walter Willinger
