Patent number: 11811591Abstract: Embodiments of the present disclosure provide methods and apparatuses for network communication. A method comprises determining a link between an edge device of a second network and the first edge device of the first network is failed or the edge device of the second network is failed or an identifier of an Ethernet segment corresponding to the edge device of the second network has been changed; and advertising a first message including withdrawal of the Ethernet segment corresponding to the edge device of the second network and a corresponding substitution Ethernet segment of the second network, wherein the corresponding substitution Ethernet segment of the second network can be used by one or more other edge devices of the first network receiving the first message to switch routes associated with the Ethernet segment corresponding to the edge device of the second network to the corresponding substitution Ethernet segment of the second network.Type: GrantFiled: May 31, 2019Date of Patent: November 7, 2023Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Jiang He, Zhenning Zhao, Bolin Nie

Patent number: 11444798Abstract: Methods and apparatus are provided for processing communications. In one aspect, a method of processing Flex Ethernet (FlexE) data comprises receiving a plurality of data blocks over at least one physical layer connection, each data block corresponding to one of at least one FlexE client flow, wherein data blocks corresponding to a first client flow of the at least one FlexE client flow have a destination over at least one further physical layer connection and contain Ethernet packets and Operation, Administration & Management (OAM) blocks, forming at least one further Ethernet packet containing at least one of the OAM blocks, the at least one further Ethernet packet specifying the destination, and providing the at least one further Ethernet packet to a switching node for forwarding to the destination.Type: GrantFiled: December 22, 2017Date of Patent: September 13, 2022Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (publ)Inventors: Jun Deng, Zhenning Zhao

Publication number: 20220264372Abstract: Methods and apparatuses for communication between a radio equipment and a radio equipment controller are disclosed. According to an embodiment, a first transport equipment detects a bit rate of one of a radio equipment and a radio equipment controller. The one of the radio equipment and the radio equipment controller is connected with the first transport equipment through a first common public radio interface (CPRI) link. The first transport equipment locks a working bit rate of a first CPRI port of the first transport equipment to the detected bit rate. The first transport equipment generates a message indicating the detected bit rate and sends the message to a second transport equipment that is connected with the other of the radio equipment and the radio equipment controller through a second CPRI link.Type: ApplicationFiled: July 19, 2019Publication date: August 18, 2022Inventors: Jun Deng, Shujie Yang, Zhenning Zhao

Patent number: 9523628Abstract: The present invention provides a method and an apparatus for determining separation efficiency of a cyclone separator. The method comprises: collecting solid particles separated by a cyclone separator; performing a particle size analysis for the collected solid particles; calculating feature parameters of the collected solid particles according to a result of the particle size analysis, wherein the feature parameters are values representing particle size and particle size uniformity of the solid particles; and determining a separation efficiency corresponding to the feature parameters of the collected solid particles as a separation efficiency of the cyclone separator, according to a predetermined correspondence between feature parameter and separation efficiency. The present invention avoids the difficulty in directly measuring the material concentrations at the inlet and the outlet of the cyclone separator and has a small interference with the apparatus.Type: GrantFiled: October 30, 2013Date of Patent: December 20, 2016Assignees: North China Electric Power Research Institute Co., Ltd., State Grid Corporation of ChinaInventors: Jinjing Li, Zhanguo Li, Zhenning Zhao, Shuo Yang
