Abstract

The invention discloses a method for the shutdown and startup of a wireless communication terminal. The method comprises the following steps of: starting the shutdown of the wireless communication terminal; cutting off power supplied to a communication processor and a radio frequency antenna; cutting off power supplied to an application processor and a central processing unit (CPU); maintaining power supplied to a random access memory; starting the startup of the wireless communication terminal; supplying power to the application processor and the CPU; and supplying power to the communication processor and the radio frequency antenna. By the technical scheme, the shutdown and startup of an intelligent wireless communication terminal can be accelerated, startup time is shorter than a second, all functions can be instantly used after the startup, the startup is quite approximate to real shutdown, and can be used on an airplane, and battery power consumption is low.

Description

A kind of wireless communication terminal closes starting-up method

Technical field

The present invention relates to the wireless communication terminal technical field, relate in particular to a kind of wireless communication terminal and close starting-up method.

Background technology

Along with the popularization of intelligent wireless communication terminal, the function at terminal becomes increasingly complex, and the thing that do is more and more, so cause the speed of starting up of terminal more and more slower.

In order to improve the starting up speed at terminal; To be start time be placed on the front to the thing of necessity to present modal way; Such as showing home at first; Search network as soon as possible,, be placed on such as the thing of media research and so on and do not carrying out when master slave system was in a hurry in one or two minute after the start then a lot of other things.But it is big that the shortcoming of this practice is a technical difficulty, and optimize codes is many, introduces problem easily, and some postpones the function of execution and will be again could use a little later the time.

It is to carry out snapshot to system that a kind of mode is arranged in addition, is kept at then among the nand flash, recovers on-the-spot when start shooting next time; When being system closedown random asccess memory (Random Access Memory; RAM) reflection is saved among the nand flash, in the time of system boot, recovers RAM.This practice also has shortcoming: 512MB RAM needs the big quantity space of nand flash, and hardware cost raises, and software change code is many, introduces problem easily; Be subject to nand flash writing rate, write the 512M content to nand flash, perhaps compressing the 512M content also needs the time, so the unused time can increase; Be subject to nand flash reading rate, reading the 512M content, to be stored among the RAM time also short, and it is obvious inadequately that starting up speed is optimized effect, needed for ten seconds at the soonest.

Also have a kind of mode, can get into sleep state when system is no at ordinary times, under this state, CPU gets into the idle state, and the frequency vanishing is in some system even can will be zero with CPU voltage; All application processors (being ancillary equipment) get into holding state, and power consumption is few; Communication processor is still in work, owing to will accept phone and short message; RAM keeps content; The different system of complete machine power consumption this moment is different, and representative value is 2-5mA; This recovering state is that the normal condition time is very fast, only need recover CPU and get final product, and the time probably is in one second.But the shortcoming of this method is that the 2-5mA power consumption is big, and battery continues power consumption, and being not really is can not take this kind state on real shutdown, the especially aircraft.

Summary of the invention

The objective of the invention is to propose a kind of wireless communication terminal and close starting-up method, can realize closing fast start, and can power saving.

For reaching this purpose, the present invention adopts following technical scheme:

A kind of wireless communication terminal closes starting-up method, may further comprise the steps:

A, wireless communication terminal start shutdown;

The power supply of B, communication close processor and radio-frequency antenna;

C, close the power supply of application processor and CPU;

D, keep to random asccess memory and supply power;

E, wireless communication terminal start start;

F, to application processor and CPU power supply;

G, to the power supply of communication processor and radio-frequency antenna.

Among the step D, supply power to random asccess memory through battery.

Said application processor further comprises WIFI equipment, bluetooth equipment, infrared equipment, serial equipment, GPS equipment, displaying screen controller and KBC.

Adopted technical scheme of the present invention, can accelerate the pass available machine time of intelligent wireless communication terminal, the available machine time was less than one second; After the start, all functions all can be used immediately, extremely near the really shutdown of meaning; Can use this state on the aircraft, the battery power consumption is minimum.

Description of drawings

Fig. 1 is the flow chart that wireless communication terminal closes start in the specific embodiment of the invention.

Embodiment

Further specify technical scheme of the present invention below in conjunction with accompanying drawing and through embodiment.

The purpose of technical scheme of the present invention is to realize that intelligent wireless communication terminal closes start fast, and three layers of meaning are arranged here, the one, and fast, fast than present pass starting up speed; The 2nd, shutdown should not reach and can exert an influence to external world, and power consumption simultaneously is extremely low; The 3rd, start, promptly all functions in start back can both be used.

Fig. 1 is the flow chart that wireless communication terminal closes start in the specific embodiment of the invention.As shown in Figure 1, this flow process may further comprise the steps:

Step 101, wireless communication terminal start shutdown, such as pressing shutdown button or timing shutdown etc.

Step 102, (perhaps be called BBP, Baseband Processor is BP) with the power supply of radio-frequency antenna to close the communication processor of wireless communication terminal.This step can be turned off the electric current about 2mA, and the time probably needs 1-2 second.

Step 103, the application processor that continues to close wireless communication terminal (are also referred to as ancillary equipment; Application Processor; AP) and the power supply of CPU, application processor further comprises WIFI equipment, bluetooth equipment, infrared equipment, serial equipment, GPS equipment, displaying screen controller and KBC.This step is consuming time to be no more than 3-5 second.

Step 104, through battery keep to random asccess memory (Random Access Memory, RAM) power supply, preserve wireless communication terminal all working state information like this among the RAM.

Under such off-mode, system's power consumption is about 500uA-1mA, and some can reach 500uA through the system power of optimizing, and is more or less the same with normal tradition shutdown 200uA.And under this off-mode, communication processor is no longer worked, and therefore can not exert an influence to external world, and is the same with the state of normal tradition shutdown.

Step 105, wireless communication terminal start start, such as pressing start button or timing start-up etc.

Step 106, at first to application processor and CPU power supply.

Step 107, then to the power supply of communication processor and radio-frequency antenna.

Because when wireless communication terminal starts start; RAM preserves the preceding wireless communication terminal all working state information of shutdown; And do not need from the beginning to move, the user can just can use all functions of wireless communication terminal soon, so the time of user's start can be less than 1 second.

The above; Be merely the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, anyly is familiar with this technological people in the technical scope that the present invention disclosed; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
