Patent number: 10506313Abstract: Embodiments relate to the field of PON technologies, and provide a method, apparatus, and system. The method includes: receiving capability information that is sent by an ONU by using a first preamble; calculating a tap coefficient based on the received first preamble if the capability information indicates that the ONU has an equalization capability; sending the tap coefficient to the ONU, where the ONU updates a tap coefficient of a first equalizer in the ONU based on the received tap coefficient, and when subsequently sending upstream data, sends, by using a second preamble, the upstream data equalized by using the first equalizer, and a length of the second preamble is less than a length of the first preamble; receiving the upstream data; and equalizing the received upstream data based on the second preamble by using a second equalizer in an OLT. In this way, upstream overheads can be reduced.Type: GrantFiled: December 13, 2018Date of Patent: December 10, 2019Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Jianyu Zheng, Shengping Li, Xuming Wu

Publication number: 20060105713Abstract: A Wireless Connection Utility (WCU) provides a unified user experience for managing various types of wireless connections, including Wireless WANs, Wireless LANs, and Bluetooth networks. The WCU functions as a gateway for a user of a computer to monitor the computer's wireless network status, to switch wireless connections, to configure wireless connection settings, and to diagnose wireless connection problems through a Wireless Helper Utility (WHU). The WCU thus provides a unified U/I layer on the top of the existing operating system components for ease of use.Type: ApplicationFiled: January 24, 2005Publication date: May 18, 2006Inventors: Jianyu Zheng, Mark Hanson, Djung Nguyen

Publication number: 20050102537Abstract: A method is disclosed for communicating using a device having a Palm OS. SMB is preferentially used to communicate with a node, and if use of SMB is not possible, FTP is used, and if use of FTP is not possible, Bluetooth is used. If FTP or Bluetooth is selected as the protocol, file sharing between the device and node that entails a read or write is executed by temporarily copying a file to an internal Palm OS memory of the device, performing the read or write on the file, and then copying the file back to the node to overwrite a previous version of the file at the node. For non-Palm OS file transfer to the internal memory, the file is wrapped in a Palm OS stream in the internal memory for executing reads or writes. For file transfer to an expansion Palm OS memory card, byte-to-byte copying of the file is executed using the FAT of the expansion memory, with the file being transferred through an internal Palm OS memory of the device.Type: ApplicationFiled: October 12, 2004Publication date: May 12, 2005Inventor: Jianyu Zheng
