Embodiment Construction

[0100] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0101] The terminology used in the present disclosure is for the purpose of describing particular embodiments only, and is not intended to limit the present disclosure. As used in this disclosure and the appended claims, the singular forms "a", "the", and "the" are intended to include the plural forms as well, unless the context clearly dictates otherwise. It should also be understood...

Abstract

The disclosure relates to a system time correction method and device, a terminal and a router. The method comprises the steps that current time information is acquired by a mode except for reading system time when waking up from the dormant state; and current system time is corrected on the basis of the current time information. With application of the disclosed embodiment, the current time information can be acquired by the terminal or the router when waking up from the dormant state, and current system time can be corrected on the basis of the acquired time information. A system clock stops working under the dormant state, and control logic errors are caused by inaccurate time when waking up from the dormant state. Therefore, current time is acquired by the mode except for reading system time when the terminal or the router wakes up from the dormant state, and system time is corrected so that system time accuracy and control logic precision can be guaranteed.

Description

technical field [0001] The present disclosure relates to the technical field of network communication, and in particular to a system time correction method, device, terminal and router. Background technique [0002] In order to reduce the power consumption of the system, a common practice at present is to make the MCU (Microcontroller Unit, micro control unit) of the device enter the dormant state when there is no business to be processed, and wake up from the dormant state when there is a business to be processed. [0003] In related technologies, the time of many embedded systems depends on the system systick (heartbeat timer), that is, the system timing clock. But when MCU enters dormancy state, the clock of CPU (Central Processing Unit, central processing unit) and peripheral controller all can stop, that is to say, heartbeat timer also can stop working, so when MCU wakes up from dormancy state, The clock at this time is wrong, which will lead to some control logic erro...
