Patent number: 9935866Abstract: The present invention relates to systems and methods for last mile optimization for the transmission of real-time data. Pseudo-packets are sent to a last mile optimizer located at each of several ‘best’ servers. The last mile optimizers provide feedback regarding jitter, latency and packet loss of the pseudo-packets to determine quality of service for each of the servers. The server with the best quality of service is selected as the ‘single best’ server. A plurality of transporter algorithms may then be applied to pseudo-packets that are then sent to the single best server, and the quality of service for each transporter algorithm is subsequently measured for effectiveness. The transporter algorithms that are shown to be effective are combined together for the actual transmission of real-time data. Continuous monitoring of transmission quality allows for utilizing backup pathways upon detection of a problem, and negotiation of preferred transporter algorithms.Type: GrantFiled: February 24, 2016Date of Patent: April 3, 2018Assignee: Agora Lab, Inc.Inventors: Bin Zhao, Wei Li

Patent number: 9847863Abstract: Methods are disclosed for supporting transmission of broadcast messages using multiple types of control channels. An example method begins with receiving (1110) a message from each of several user terminals, each message indicating whether the corresponding user terminal supports the receipt of broadcast messages via the second control channel type. In some embodiments, one or more of these messages may indicate that the corresponding user terminal monitors only the second control channel type for broadcast messages. The control node subsequently initiates (1120) a transmission of a broadcast message to one of the user terminals from one or more base stations in a tracking area for the user terminal. This initiation includes indicating to the one or more base stations whether user terminal supports the receipt of broadcast messages via the second control channel type, based on information earlier received by the control node.Type: GrantFiled: January 30, 2013Date of Patent: December 19, 2017Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Daniel Larsson, Robert Baldemair, Jung-Fu Cheng, Mattias Frenne

Patent number: 9832811Abstract: Methods and apparatus to reduce power consumption in user equipment (UE) that operates in a connected discontinuous reception (C-DRX) mode while in communication with wireless network are disclosed. A C-DRX warm-up period before the UE enters an on-duration is adjusted dynamically based on one or more factors including a time division duplex (TDD) uplink/downlink (UL/DL) subframe configuration, signal-to-noise ratio (SNR) values, and Doppler shift values. The C-DRX warm-up period is adapted based on the pattern of DL subframes in the UL/DL subframe configuration by including DL subframes that best contribute to channel estimation and adaptive tracking loops based on measured SNR and Doppler shift conditions. Favorable channel conditions, such as higher SNR and lower Doppler shift, can require fewer DL subframes and consequently shorter C-DRX warm-up periods. Higher Doppler shift values indicate more rapidly varying channel conditions and require DL subframes positioned closer to the start of the on-duration.Type: GrantFiled: March 28, 2016Date of Patent: November 28, 2017Assignee: Apple Inc.Inventors: Zhu Ji, Johnson O.
