  • Patent number: 11503560
    Abstract: Embodiments of this application provide a time synchronization offset adjustment method and apparatus, a terminal, and an access layer device. The method includes: compensating, on a 1588 terminal or an access layer device based on a 1588 time offset value, for a 1588 time obtained through synchronization. This reduces an error caused by asymmetric delays on transmit and receive links, and improves precision of the 1588 time obtained through synchronization.

  • Publication number: 20210160799
    Abstract: This application provides a clock state detection method and apparatus, applied to the field of communications technologies, to detect clock states of M base stations. The method includes: receiving detection results of M base stations, where the detection result of each of the M base stations is used to indicate whether the base station receives a detection sequence sent by each of N neighboring stations of the base station, the N neighboring stations belong to the M base stations, both M and N are integers greater than or equal to 1, and N is less than M; and determining clock states of the M base stations based on the detection results of the M base stations.

  • Publication number: 20200014628
    Abstract: A method for traffic control are provided, includes: obtaining, by a control node, a delay prediction value of a service packet sent by a source node to a destination node after a current moment; and determining, by the control node, a congestion detection result of current traffic transmission based on a packet delay variation trend and the delay prediction value, and sending the congestion detection result to the source node, and the packet delay variation trend corresponds to a congestion duration change.
