Abstract

The embodiment of the invention provides a fingerprint module sleep wake-up method and device. The method comprises the steps as follows: judging if a sleep notice exists in a kernel layer; enabling apreregistered fingerprint module to sleep if the sleep notice exists in the kernel layer; judging if a preset wake-up event is triggered in the kernel layer; and waking up the sleeping fingerprint module if the preset wake-up event is triggered in the kernel layer. According to the fingerprint module sleep wake-up method provided by the embodiment of the invention, the preregistered fingerprint module goes to sleep if the sleep notice exists in the kernel layer of an intelligent terminal and the sleeping fingerprint module is waken up when the wake-up event is triggered, so as to wake up thesleeping fingerprint module while the intelligent terminal system is waken up from sleep; therefore, the power consumption of the intelligent terminal is reduced and the duration of the intelligent terminal is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a method and device for waking up a fingerprint module from sleep. Background technique [0002] In recent years, with the strong support of national policies and the continuous efforts of enterprises in the industry, my country's smart terminal industry has developed rapidly, and the use of smart terminals is showing an upward trend year by year. The popularity of smart terminals has brought earth-shaking changes to people's production and life. The introduction of fingerprint modules in smart terminals makes the use of smart terminals more convenient and safer. For example, a fingerprint module is introduced into an Internet of Things terminal to realize functions such as fingerprint unlocking and fingerprint verification, and a fingerprint module is introduced into a mobile terminal to realize functions such as fast unlocking, fast login, and...
