Document Type and Number:
WIPO Patent Application WO/2022/042748
Kind Code:
A1
Abstract:
Embodiments of the present application provide a method and device for measuring time deviation, relating to the field of terminals and capable of saving device power consumption. The method comprises: a first device sends a first message to a second device, and acquires the virtual sending time of the first message t1, t1 being determined according to a first offset and system time, the first offset comprising a first initial value and a jump of the system time of the first device; the first device receives from the second device a response message for the first message, and acquires the virtual receiving time of the response message for the first message t2, t2 being determined according to the first offset and the system time, wherein the response message for the first message carries the virtual receiving time t1' at which the second device receives the first message and the virtual receiving time t2' at which the second device sends the response message of the first message; and the first device determines a first virtual time deviation between the first device and the second device according to t1, t2, t1' and t2', and stores the first virtual time deviation.
