TIMELINESS GUARANTEE METHOD, APPARATUS AND SYSTEM

WIPO Patent Application WO/2023/231864

A1

Embodiments of the present application provide a timeliness guarantee method, apparatus and system, applied to the communication technology. The method comprises: a network device receiving a data frame, the data frame comprising timeliness information; obtaining a transmission delay on the basis of a start moment of a link layer of the network device receiving the data frame and a termination moment of the link layer receiving the data frame; obtaining an overall forwarding delay on the basis of the time required by a protocol stack or an application layer of the network device to process the data frame; updating the timeliness information on the basis of the transmission delay and the overall forwarding delay; and sending the updated data frame. According to the present application, the network device and/or a receiving terminal can update the timeliness information of the data frame, such that the receiving terminal can determine whether the data frame is valid or not on the basis of the updated timeliness information. The method does not need to keep the time synchronization of a sending terminal, the receiving terminal, and the network device.
