Patent number: 11937299Abstract: A method of setup a protection mechanism for scheduled transmissions to multiple stations is introduced. Through transmitting a control frame addressing to multiple stations for immediate simultaneous responses, the transmitter would know the stations that are ready for receiving the scheduled data frames and schedule the packet for those stations. Combining the transmission of the control frame with the power saving mechanism would allow triggering a group of power saving stations to wake up at same for receiving the control frame and scheduled user data frames. A new mechanism of simultaneous group responses to the control frame with orthogonal identifier information for individual station is provided to uniquely identify the responding stations.Type: GrantFiled: April 24, 2020Date of Patent: March 19, 2024Assignee: ZTE CorporationInventors: Kaiying Lv, Bo Sun, Kaibo Tian, Weimin Xing, Yonggang Fang

Patent number: 10075869Abstract: A data transmission method and apparatus are provided. The method comprises: receiving service data sent by a first terminal, the first terminal being a single-mode terminal or a multi-mode terminal; monitoring forwarding load traffic of a back-end egress of a first network device in a first network; when the load traffic reaches present load traffic, switching a current forwarding mode to a routing mode, and selecting a second terminal as a forwarding node of the first terminal, the second terminal being a multi-mode terminal; forwarding the service data to the second terminal, so that the second terminal coverts the service data and sends the converted service data to a second network device in a second network. According the embodiments of the present invention, the technical problem of a low utilization rate of the total bandwidth of a network egress in the prior art is solved.Type: GrantFiled: June 27, 2014Date of Patent: September 11, 2018Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Liang Yang, Ning Fei, Jiannong Cao, Huimin Zhang, Yonggang Tian

Patent number: 9479999Abstract: Embodiments of the present invention disclose a vehicular communication method, including: acquiring a current position of a vehicle; acquiring all fixed APs, the distance from each of which to the current position of the vehicle is smaller than its maximum transmission distance; scanning all the fixed APs in a scheduling period; selecting at least one fixed AP of which signal strength is greater than a preset value in all the fixed APs as a to-be-accessed fixed AP according to the scanning results; and triggering a mobile terminal in the vehicle to respectively access a vehicular AP in the vehicle and the to-be-accessed fixed AP in the scheduling period according to allocated time when an access condition is satisfied. The embodiments of the present invention further disclose a vehicular communication device and system. Through the above technical solutions, the communication bandwidth is increased and bulk data service is supported.Type: GrantFiled: June 19, 2014Date of Patent: October 25, 2016Assignee: Huawei Technologies Co., Ltd.Inventors: Jun Zhang, Jiannong Cao, Yonggang Tian

Patent number: 8730958Abstract: Embodiments of the present invention disclose Wireless Mesh Network (WMN) for notifying proxy update. By constructing the proxy update add message, where the proxy update add message includes the address of terminal, the current proxy node address after terminal switching and the destination node address of the terminal, and taking the address of the original proxy node before terminal switching as the address of the destination node, and sending the proxy update add message constructed to the original proxy node, where the proxy update add message is used for updating proxy information of the terminal in the proxy information table of the original proxy node to be the current proxy node address. It makes sure that packets received by the original proxy node which should be sent to the terminal could be received by the terminal, and packet loss rate during terminal switching could be reduced.Type: GrantFiled: October 12, 2012Date of Patent: May 20, 2014Assignee: Huawei Technologies Co., Ltd.Inventors: Dangfeng Feng, Xuming Fang, Shujie Sun, Yonggang Tian
