Patent number: 11005706Abstract: A method for configuring a forwarding table for user equipment, an apparatus, and a system, where an operator server receives a service access request of user equipment, establishes a correspondence for the user equipment, and sends the correspondence to an access node (AN) controller. The correspondence includes a media access control (MAC) address of the user equipment and an identifier of an operator to which the user equipment belongs. The AN controller generates a first forwarding table according to the correspondence, and sends the first forwarding table to an AN. The AN forwards, using the first forwarding table, service data of the user equipment to the operator to which the user equipment belongs.Type: GrantFiled: December 22, 2017Date of Patent: May 11, 2021Assignee: HUAWEI TECHNOLGOIES CO., LTD.Inventors: Yuanling Bai, Wenle Yang, Ruobin Zheng

Publication number: 20200274948Abstract: This application provides a service flow configuration method. In the method, a control device receives a first DHCP packet sent by a DHCP server, where the first DHCP packet includes an IP address of a server configured to provide a configuration file, an identifier of the configuration file, and an IP address of a user-side terminal. The control device replaces, with an IP address of the control device, the IP address being in the first DHCP packet and being of the server configured to provide the configuration file, and sends the IP address of the control device to the terminal by using a second DHCP packet. The control device receives a first request packet including the identifier of the configuration file. The control device obtains, based on the identifier of the configuration file from the server configured to provide the configuration file, a configuration file corresponding to the terminal.Type: ApplicationFiled: May 13, 2020Publication date: August 27, 2020Applicant: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Wenle Yang, Ruobin Zheng

Patent number: 8473997Abstract: Embodiments of the present disclosure provide a channel changing method, apparatus, and system. A network side device records in real time a timestamp of a media packet of a multicast media stream which enters a buffer, and a key frame which enters the buffer; when a terminal's channel changing request has been detected, obtains a first timestamp of a media packet which enters the buffer at a channel changing request moment, and a second timestamp of a media packet in which a key frame which is of the target channel and is the last to enter the buffer is located in the media packet; determines a timestamp difference between the first timestamp and the second timestamp; and transmits the timestamp difference and a burst media stream of the target channel to the terminal. In the embodiments of the present disclosure, a delay in playing the multicast media stream by the terminal is reduced.Type: GrantFiled: August 3, 2012Date of Patent: June 25, 2013Assignee: Huawei Technologies Co., Ltd.Inventors: Zhigang Qiu, Kai Guo, Wenle Yang, Xia Qin, Hewen Zheng
