Sleep/wake-up timing deviation compensation method and electronic equipment

Abstract

The invention discloses a sleep / wake-up timing deviation compensation method and electronic equipment. The method comprises the following steps of obtaining the sleep duration of a first timer needing to enter a sleep state; according to a time point T1 when the first timer enters the sleep state and the sleep duration, calculating a wake-up time of the first timer; obtaining a time point T2 recorded when a second timer which does not enter the sleep state wakes up the first timer; and according to an error between the T2 and the calculated wake-time time point, adjusting the timing deviation of the first timer. Based on the second timer which does not go through the sleep state, timing compensation of sleep timing errors at the wake-up time of the first timer which goes through the sleep state is achieved, so that the problem that the timing deviation is caused by switching from sleep to slow clock after the first timer is waken up is solved, and the problem of sleep / wake-up timing deviation compensation of a system minor mode timer is effectively solved.

Description

technical field [0001] The invention relates to the communication field, in particular to a compensation method and electronic equipment for sleep and wake-up timing deviations in the communication field. Background technique [0002] In the current communication system, in order to reduce the power consumption of the chip, the chip is usually in a sleep state when not working. When the chip switches from the sleep state to the working state, the terminal needs to synchronize time with the base station. For this reason, the timer provides two working modes, normal counting mode and slow timer mode. In the normal counting mode, the timer counts with the sampling clock of this mode (generated by the frequency division of the fast clock). For the GSM mode, the counting frequency is 1.08MHz. For the TD mode, the counting frequency is 1 / 8 chip, that is, 10.24MHz , for TD-LTE and LTE FDD modes, the counting frequency is 30.72MHz. In the slow timer mode, the slow timer counts wi...
