Method and device for preventing mobile phone from being woke-up in stand-by state

Abstract

The invention relates to a method and a device for preventing a mobile phone from being awakened for no reason in a standby state. The method comprises the following steps: a, in a presetting time when no user operation events occur, setting a turn-on key connected to a power supply management chip as an external awakening interrupt source, setting an input device connected to a baseband processor as a banned awakening interrupt source when the mobile phone is in a standby state, closing a display screen of the mobile phone and entering the standby state; b, in the standby process, the mobile phone baseband processor detecting whether awakening interrupt events caused by the turn-on key or the interior interrupt exist or not; if no, returning to the step b until that the awakening interrupt events caused by the turn-on key or the interior interrupt exist; if so, then executing the step c; c, the mobile phone baseband processor unbanning the unbanned awakening interrupt source and starting the display screen; d, returning to the step a after executing the user commands. The device comprises a preprocessing module, a detection module, an awakening module and an execution module. The method and device can prevent the user from dialing phone numbers by mistake, save energy and be widely applied to mobile communication systems.

Description

technical field [0001] The invention relates to system embedding technology, in particular to a method and device for preventing a mobile phone from being woken up without reason in a standby state. Background technique [0002] The mobile phone keyboard, touch screen or rolling ball are man-machine interface input devices. Generally, the mobile phone keyboard, touch screen, and rolling ball are connected to the baseband processor of the mobile phone and are set as the external wake-up interrupt source of the system. figure 1 It is a flow chart of waking up a mobile phone from a standby state in the prior art. Such as figure 1 As shown, when the user is not using the mobile phone, the mobile phone usually turns off the screen and other devices and enters the standby state; all wake-up interrupts generated during the standby process will trigger the wake-up mechanism of the mobile phone system and enter the wake-up process; Whether the wake-up interrupt event is an unintent...

AI Technical Summary

Problems solved by technology

A mobile phone with a touch screen, although it also has a keyboard lock function, but in the system standby state, as long as the touch screen is touched, a wake-up interrupt will be generated, the phone will be woken up from the standby state, and even the touch screen will be turned on to display that the user's keyboard is locked, etc. hint

[0004] It can be seen that in the prior art, no matter whether the mobile phone keypad has a locking function or not, when the mobile phone keypad, touch screen or rolling a ball is unintentionally touched, a wake-up interrupt will be generated, and the mobile phone will be woken up from the standby state. Higher rate, greater energy waste
