Title:
TIME DELAY COMPENSATION METHOD AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/207636
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present application is a time delay compensation method. The method can be applied to a fine granularity service scenario, and comprises: a first communication apparatus determines a first transmission time delay, the first transmission time delay indicating a transmission time delay of a fine granularity service in the first communication apparatus; the first communication apparatus sends the first transmission time delay to a second communication apparatus. By means of the method, it is ensured that a service bit stream sent by a sink node meets the time delay compensation requirement, and thus it is ensured that a network transmission time delay from a source node to the sink node and a network transmission time delay from the sink node to the source node in a fine granularity service network are equal or fall within the expected error range, or a network transmission time delay from a source node to the sink node and a network transmission time delay from the sink node to the source node are adjusted to the expected values so as to meet the service requirement. For example, when the time delay compensation method provided by the embodiments of the present application is applied to a power grid system, it is ensured that the moments of information acquisition between any two terminal devices are consistent.
