Patent number: 9654950Abstract: 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.Type: GrantFiled: January 14, 2016Date of Patent: May 16, 2017Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Subhabrata Sen, Oliver Spatscheck, Alexandre Gerber, Zhuoqing Morley Mao, Feng Qian, Zhaoguang Wang

Publication number: 20160286415Abstract: 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: ApplicationFiled: June 10, 2016Publication date: September 29, 2016Inventors: Alexandre Gerber, Zhuoqing Mao, Feng Qian, Subhabrata Sen, Oliver Spatscheck, Zhaoguang Wang

Patent number: 9220066Abstract: 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.Type: GrantFiled: June 20, 2011Date of Patent: December 22, 2015Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Alexandre Gerber, Zhuoqing Mao, Feng Qian, Subhabrata Sen, Oliver Spatscheck, Zhaoguang Wang
