Abstract: This application provides a communication method and apparatus. The method includes: A first device determines information about service flow arrival time, where the information about the service flow arrival time includes the service flow arrival time or an offset of the service flow arrival time relative to reference time, the service flow arrival time is time at which a first service flow arrives at a second device, and the first service flow is a periodic service flow to be transmitted between an access network device and a user plane network element. The first device determines information about service flow sending time based on the information about the service flow arrival time. The first device indicates the second device to wait, after receiving the first service flow, until the service flow sending time to send the first service flow. If the first service flow is an uplink service flow, the second device is the access network device or a translator corresponding to the access network device; or if the first service flow is a downlink service flow, the second device is the user plane network element. According to the foregoing method, a deterministic latency requirement of the first service flow can be met, and overall network performance can be improved.

Abstract: Embodiments of this application disclose a data transmission method and a device therefor, applied to a scenario of Ethernet packet transmission. The method in embodiments of this application includes: A first device receives a first packet. Load data in the first packet includes padding redundant data. The first device deletes the padding redundant data. The first device generates a second packet. Load data in the second packet is payload data obtained after the padding redundant data is deleted from the first packet. The first device sends the second packet to a second device. In embodiments of this application, the first device deletes the padding redundant data from the first packet, so that the padding redundant data does not need to be transmitted during air interface transmission, thereby saving air interface resources and improving an air interface capacity.

Abstract: This application provides a communication method and a communications apparatus. In the communication method, an SMF network element determines, according to a PCC rule of a flow, a third latency of transmitting the flow from a UPF network element to UE, so that a second latency of transmitting the flow from a flow service provider in a TSN to the UE can be determined based on the third latency and a first latency of transmitting the flow from the flow service provider in the TSN to the UPF network element. The communication method and the communications apparatus provided in this application use a relatively simple implementation to determine an accumulated latency of transmitting the flow from the UPF network element to the UE, that is, use a relatively simple manner to determine an accumulated latency of transmitting the flow from the flow service provider in the TSN to the UE.

Abstract: This application provides a downlink transmission method and a communication apparatus. A session management network element obtains duration, namely, a first delay, between an expected moment at which a downlink service packet arrives at an access network element and an estimated moment at which the downlink service packet arrives at the access network element, where the expected moment at which the downlink service packet arrives at the access network element is within a first scheduling window, and a next scheduling window adjacent to the first scheduling window is a downlink scheduling window. Then, the session management network element sends time adjustment information related to the first delay to a user plane network element or an application network element, where the time adjustment information is used by the user plane network element to determine a first moment at which the downlink service packet is sent or used by an application server to determine a second moment at which the downlink service packet is sent, and a moment at which the downlink service packet sent by the user plane network element at the first moment or sent by the application server at the second moment arrives at the access network element is within the first scheduling window. This solution can reduce a scheduling delay on an access network element side.

Abstract: This application provides a method for configuring assistance information and a communications apparatus. The method includes the following steps: A first network device sends a path switch request message to an access and mobility management function AMF, where the path switch request message is used to request for switching least one radio bearer RB of a terminal device from a second network device to the first network device. The first network device receives a path switch request response message from the AMF. The first network device determines, based on the path switch request response message, first burst arrival time at which a downlink quality of service QoS flow arrives at an ingress of the first network device within a first periodicity, where the first burst arrival time is used for downlink scheduling. According to the method, signaling overheads can be reduced, and a delay generated in obtaining burst arrival time can be reduced, thereby further saving a system function and improving system performance.

Abstract: This application provides a time synchronization packet processing method and apparatus. The method includes: A terminal device receives first indication information, where the first indication information indicates the terminal device to enter an activation state of time synchronization for a first clock source, or the first indication information indicates the terminal device to enter a deactivation state of time synchronization; and processes a time synchronization packet of the first clock source based on the first indication information. The clock synchronization packet is processed in different manners when the time synchronization of the first clock source is in the activation state and the deactivation state, so that the terminal device can perform processing in different manners when signaling indicates that the clock source is activated or deactivated. For example, when the first clock source is in the deactivation state, the terminal device does not need to perform processing that needs to be performed when the first clock source is in the activation state. Therefore, power consumption of a communication device is reduced, and performance of the communication device is improved.

Abstract: This application provides a service packet transmission method and apparatus. The method includes: A target user plane network element receives a first uplink service packet from a source user plane, where the first uplink service packet is an uplink service packet received by the source user plane after the source user plane receives a second uplink service packet, and the second uplink service packet is the last uplink service packet sent by the source user plane to a source application server; the target user plane network element receives first indication information from the source user plane network element, where the first indication information is used to indicate that sending of the first uplink service packet by the source user plane network element ends; and after the target user plane network element receives the first indication information, the target user plane network element sends, to a target AS after the first uplink service packet is sent, an uplink service packet that is sent by an access network device to the target user plane network element, so that out-of-order of uplink service packets can be avoided. This helps improve transmission performance.
