Patent number: 9584229Abstract: A data retransmission method, apparatus, and system can improve a success ratio of data packet retransmission. A data retransmission method includes: after a source node continuously transmits at least two data packets to a destination node according to a go-back-N automatic repeat request, monitoring and decoding, by a relay node, the at least two data packets; storing a copy of a successfully decoded data packet; monitoring a response message to each data packet, where the response message is returned by the destination node to the source node; and sending a copy of a data packet that corresponds to a reception negative acknowledgment message to the destination node, when the monitored response message is the reception negative acknowledgment message.Type: GrantFiled: May 23, 2013Date of Patent: February 28, 2017Assignee: HUAWEI DEVICE CO., LTD.Inventor: Zhenwei Chen

Publication number: 20140215034Abstract: The present invention provides a processing method and processing device for automatically setting an Internet access mode. The method includes separately sending a PPPoE request message and a DHCP request message; if a DHCP response message corresponding to the DHCP request message is received first within a set time, determining that the Internet access mode is a DHCP mode; if a PPPoE response message corresponding to the PPPoE request message is received later within the set time, determining that the Internet access mode switches from the DHCP mode to a PPPoE mode. Embodiments of the present invention can improve accuracy of mode detection.Type: ApplicationFiled: December 26, 2013Publication date: July 31, 2014Inventors: Zhenwei Chen, Tao Wei

Patent number: 8094567Abstract: A method for transferring test messages includes a Network Element (NE) A and NE B negotiating and determining a logical channel type. The Link Management Protocol (LMP) entity of NE A constructs a test message packet which includes the local Ethernet data interface ID, and transfers the test message packet to the local packet control module. The packet control module of NE A encapsulates the test message packet according to the logical channel type determined through negotiation, and transfers the encapsulated packet to the local transmitting interface. The receiving interface of NE B identifies and receives the packet. The packet control module of NE B obtains the packet from the local receiving interface and then encapsulates the packet. Next the packet control module of NE B transfers the test message packet obtained after decapsulation to the local LMP entity.Type: GrantFiled: April 22, 2009Date of Patent: January 10, 2012Assignee: Huawei Technologies Co., LtdInventors: Feng Li, Fang Yin, Liusheng Xu, Zhenwei Chen
