Abstract: A method is provided. The method includes: receiving a handover request, from a source base station, for requesting to perform time synchronization with a target base station; and sending handover request acknowledgement information to the source base station, where the handover request acknowledgement information includes information used to indicate whether the source base station performs time synchronization with the target base station. The source base station may determine, according to the handover request acknowledgement information sent by the target base station, whether the source base station needs to perform time synchronization with the target base station.

Abstract: This application provides an isolation and recovery method and related network device for a case when one or more physical layer apparatuses (PHYs) in a flexible Ethernet group (FlexE group) are faulty. In the method, if a network device determines that a first overhead block corresponding to each current available PHY is stored in a corresponding memory, the network device determines that a FlexE group meets a PHY alignment condition, and starts to simultaneously read cached data from all memories. Therefore, there is no need to insert local fault LF code blocks to all clients, and there is no need to recreate a group. This effectively reduces the impact of a faulty PHY on client services carried by a normal PHY.

Abstract: An anti-replay method and apparatus are provided. The same maximum agreed value is set at a transmit end and a receive end. The receive end receives an Internet Protocol Security (IPSec) packet, where the IPSec packet includes a sequence number, and acquires an upper limit value of an anti-replay sliding window. If the upper limit value of the anti-replay sliding window is the maximum agreed value, the receive end sets an interval of the anti-replay sliding window to M1 to M2, where M1 is a minimum value of the packet sequence number, and M2 is a sum of M1 and a size of the anti-replay sliding window. When a sequence number of a packet sent by the transmit end reaches a maximum value, a sequence number of a next sent packet starts from the minimum value, thereby resolving a problem that a packet is falsely discarded because of anti-replay.

Abstract: In an embodiment, the application provides a flexible Ethernet (FlexE) communication method, which includes: receiving, by a first network device by using a FlexE group, n first overhead blocks sent by a second network device, the FlexE group comprising n physical layer apparatuses (PHYs); and storing, by the first network device, the n first overhead blocks in n memories in the first time period. The method further includes simultaneously reading, by the first network device, the n first overhead blocks from the n memories, after a preset duration T starting from a moment at which a first overhead block is stored in a corresponding memory. The first overhead block is a last stored first overhead block in the n first overhead blocks, the duration T is greater than or equal to one clock cycle.

Abstract: The present disclosure discloses an air-interface-based synchronization method, a base station and its control apparatus, and a wireless communications system. By taking advantage of active random access of user equipment, a time difference between base stations is acquired by detecting a random access preamble, and a time adjustment value of a non-reference base station is acquired according to the acquired time difference and reference time of a reference base station; and the non-reference base station performs time adjustment according to the acquired time adjustment value, to complete time synchronization with the reference base station. The present disclosure can easily and effectively implement air-interface-based synchronization between base stations by using an existing wireless network, thereby achieving a technical effect in a convenient and economic manner.

Abstract: An interface obtains basic page information from another interface. The basic page information includes N bits, the N bits include an FEC function indicator bit sequence including an FEC ability indicator bit and an FEC requested indicator bit. The interface determines, based on values of a plurality of bits in the N bits, an operation mode supported by the another interface. The FEC function indicator bit sequence includes a first FEC function indicator bit corresponding to m FEC abilities; or the FEC function indicator bit sequence includes a first FEC ability indicator bit corresponding to n FEC abilities, where both m and n are greater than or equal to 1. Because one FEC function indicator bit indicates more FEC abilities, N bits in a basic page can carry more information, so that a process of increasing auto-negotiation pages is slowed down, thereby avoiding impact on auto-negotiation efficiency.

Abstract: Embodiments of the present invention provide a synchronization method, a synchronization apparatus, and a base station, which can implement strict synchronization between base stations with relatively low costs and relatively high security and reliability. The method includes: determining reference user equipment UE, where the reference UE can communicate with a reference base station and a to-be-synchronized base station at the same time, and the reference base station and the to-be-synchronized base station have completed frequency synchronization relative to a same clock reference source; determining timing offset between the to-be-synchronized base station and the reference base station according to a moment at which the reference base station and the to-be-synchronized base station receive a synchronization reference signal that is sent by the reference UE; and performing calibration on the to-be-synchronized base station according to the timing offset.
