Method for shortening wakeup time of mobile terminal through prediction of user wakeup intention

Abstract

The invention relates to a method for shortening the wakeup time of a mobile terminal through the prediction of user wakeup intention. The mobile terminal has a work state and a sleep state. The method is characterized in that the mobile terminal is further provided with a pre-wakeup state. The method comprises the following steps: 1) a sensor responds to an external operation which satisfies a triggering condition to wake up a CPU (Central Processing Unit) when the mobile terminal is under the sleep state; 2) the CPU judges a reason why the CPU is woken up, and a step 4) is executed when the CPU is woken up by the sensor's response to the external operation, and a step 3) is executed if the CPU is not woken up by the sensor's response to the external operation; 3) the CPU judges the reason why the CPU is woken up, a step 5) is executed if the CPU is woken up by a wakeup module; 4) the mobile terminal enters the pre-wakeup state, a plurality of peripheral devices work, and a screen does not work; and 5) the wakeup module responds to the external operation to wake up the mobile terminal, and the mobile terminal enters the work state. The method has the advantages of being simple in steps, convenient in implementation and favorable in user experience.

Description

Technical field: [0001] The invention relates to the field of mobile terminals, in particular to a method for shortening the wake-up time of a mobile terminal by predicting a user's wake-up intention. Background technique: [0002] In order to satisfy lower energy consumption and maintain a longer standby time, mobile terminals generally have a sleep state and a working state. When the mobile terminal is in the sleep state, the system will turn off all peripheral devices, DDR enters the self-refresh mode, and the CPU stops running. When the user needs to wake up the mobile terminal, he can control the wake-up module to wake up the mobile terminal by short pressing the power button or other methods. put it into working condition. [0003] At this stage, there are more and more peripheral devices in the mobile terminal system, such as cameras, flash lights, button lights, and microphones. During the system wake-up process, each peripheral device needs to be turned on one by o...

Problems solved by technology

Since it takes a long time to turn on each peripheral device and initialize it, when the user presses the wake-up button and other actions, it takes a long time for the system to be ready. It is impossible for the display to wake up the mobile terminal after short-pressing the power button or other Light up immediately and enter the working state, the user experience is poor

[0004] Even if the mobile terminal wakes up each peripheral device concurrently, because some peripheral devices require a long initialization time, it becomes the bottleneck of the long wake-up time of the system.

At the same time, the method of concurrent wake-up also has high requirements on the hardware configuration of the mobile terminal, and its application is relatively limited.
