Problems solved by technology
The opening and closing of the device is controlled by codes. Most of the current mobile terminal standby mode is to enter the standby mode only when all the codes are not running. The disadvantage is that as long as there are codes running, the entire mobile terminal will be disabled. It cannot enter the standby mode. For example, when the camera is working, the Bluetooth function of the mobile terminal is also in the working mode, but at this time there is no event that requires Bluetooth to work, that is, the current standby mode still has a part of power consumption that is wasted

Embodiment Construction
[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0020] Such as figure 1 As described, in the present embodiment, the operating system is divided into MMI module, PS module, ATC module and BT module, the standby module is located between these modules and the system power supply module and the main clock module of the mobile terminal, between the standby module and each module There is information exchange between. The standby module also includes a mode identification module, named Sleep_mode, which is used to record the standby information of each module. It is essentially a global variable, which can be Word type, half-word or byte type, mainly depending on the system. The number of modules that can be divided depends. In this embodiment, the word type is used, and the remaining bits are reserved for future expansion of system functions. Each bit of sleep_mode represents whether different modules can e...

The invention relates to a device for controlling a stand-by state in a mobile terminal and a method, the device comorises a system power supply in the mobile terminal, a main clock module, a function module of the operating system and a stand-by module which is used for collecting the stand-by information of each function module in the operating system module and notifying the operating system module into a work mode. The method divides the operating system of the mobile terminal into modules which are independent with each other, each independent module can set self-identification as the work mode or can enter into the stand-by mode, the stand-by module collects identification information of each independent module and determines that the whole system is at the stand-by state or partly independent modules which can enter into the stand-by mode enter into the stand-by mode according to the identification information. The invention can realize grading stand-by management of the mobileterminal, determine closing the power supply of stand-by modules to reduce power consumption according to the stand-by information of each module.
Description
technical field [0001] The invention relates to the field of mobile communication, in particular to a device and method for controlling standby in a mobile terminal. Background technique [0002] At present, digital mobile terminals have various standards, such as Global System for Mobile Communication (GSM) communication standard, Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) communication standards, personal handy-phone system (Personal Handy-phone System, PHS) communication standards, wideband code division multiple access (wideband CDMA, WCDMA) communication standards, etc. Among them, each standard and the communication network matching the standard have their own characteristics in terms of signal coverage, signal emission strength, construction and operation costs, communication costs, etc. Each standard mobile terminal also has its own characteristics in terms of software and hardware implementation. different. However, no matter what kind of s...
