Abstract: This application provides a synchronization method and an apparatus, to implement synchronization with a TSN clock in a mobile network. The synchronization method is performed by a first network element in a relay network. The relay network includes a radio access network RAN device and a terminal device. The method includes: The first network element receives a clock synchronization packet. The first network element determines first duration of the relay network, where the first duration of the relay network includes a first downlink transmission delay of transmitting the clock synchronization packet between the RAN device and the terminal device. The first network element determines a time correction field of the relay network, where the time correction field includes the first downlink transmission delay.

Abstract: Embodiments of this disclosure provide a communication method and apparatus, to reduce a waiting delay during transmission of retransmitted data and out-of-order data. In this method, a user plane function network element may receive first data and second data, determines, based on first information, that the second data is retransmitted data of the first data, and sends indication information to an access network network element. The indication information herein may indicate that the second data is the retransmitted data, or indicate a sending priority of the second data. Based on this solution, the access network network element may send the first data and the second data based on the indication information, and may preferentially send the retransmitted data to reduce the waiting delay during data transmission.

Abstract: Various embodiments provide a packet transmission method and an apparatus. In those embodiments, a first device supports a first protocol layer, and replicates a packet at the first protocol layer. A second device supports a second protocol layer, and deduplicates the packet at the second protocol layer. When receiving a first packet, a first access device converts a sequence number of the first protocol layer in the first packet into a sequence number of the second protocol layer, and then sends, to the second device, a second packet that carries the sequence number of the second protocol layer and a data packet of the first packet. For example, if the first access network device receives two packets having same data packets, the first access network device separately coverts sequence numbers in the two packets without performing operations of first deduplicating and then replicating the packet.

Abstract: A paging method and apparatus are provided to simplify a prior-art paging process. The method includes: receiving, by an access device, downlink data, where the downlink data includes a first identifier of a terminal; determining a paging identifier based on the first identifier; and sending, by the access device, a paging message to the terminal, where the paging message carries the paging identifier. After the access device receives the downlink data, the access device can initiate the paging process without using a control plane network element device. The advantages of the innovative paging methods disclosed herein include reduced signaling, shortened signaling transmission, and simplified paging process.
