Description
Technical field
The present invention relates to the cell phone is the mobile communication terminal field of representative, relates to a kind of mobile communication terminal that can improve the method for professional duration of mobile communication terminal and use this method in particular.
Background technology
At present, mobile communication technology from existing be that to have developed into WCDMA, TD-SCDMA and CDMA2000 be the 3-G (Generation Three mobile communication system) of standard for the second generation mobile communication system of representative with GSM and CDMA.The 3-G (Generation Three mobile communication system) network capacity is big, can satisfy the quality of service request of mass data business, and support, is with a wide range of applications to multimedia service from speech, grouped data.
Adapt with it, mobile communication terminal also will from based on provide speech and the equipment of low speed data function to the equipment development that sophisticated functionss such as speech, high-speed data and multimedia are provided.Be the large-data operation of supporting that these are complicated, that the 3G (Third Generation) Moblie terminal has generally adopted is advanced, at a high speed, high performance flush bonding processor.When mobile communication terminal adopts these high-performance processors, also brought the contradiction of the limited flying power of used battery in the high power consumption of processor and the mobile communication terminal, this becomes the problem that the professional duration faced that improves mobile communication terminal.
Improving the professional duration of mobile communication terminal can consider from " increasing income " and " throttling " two aspects." increasing income " promptly is the power supply deliverability of increase equipment, and " throttling " then is the power consumption that reduces mobile communication terminal self.
Increasing battery capacity is a kind of " increasing income " method.Though battery technology has been made significant headway, battery life prolongs to some extent, and the volume of same battery capacity reduces or the like to some extent.But these variations can not be satisfied the energy requirement that the next-generation mobile communications terminal increases rapidly.The cost and the physical size of its meeting appreciable impact mobile communication terminal are opposing to littler lighter effort trend at present with mobile communication terminal on the one hand, also do not meet the aim of environmental protection on the other hand.
Therefore, from " throttling " angle, the power consumption how research reduces mobile communication terminal self is the important channel of improving the professional duration of mobile communication terminal.
As everyone knows, energy equals power and multiply by the time.For the mobile communication terminal application scenario, under the specified situation of battery capacity (being gross energy), the power consumption during the terminal bearer service is few more, and the professional duration will be long more.And the electrical power of electronic cost, be proportional to the supply power voltage that loads its two ends square.By reducing the supply power voltage of mobile communication terminal electronic device, its power consumption is reduced by square-law, thereby will prolong the professional duration of whole terminal.
Although processor may not be a device of power consumption in the mobile communication terminal, the power consumption of processor still is appreciable in present most of mobile communication terminals.Manage the energy consumption of processor, can increase the components and parts that are used for other function () energy for example: LCD display, keyboard etc. indirectly.For example, the mobile communication terminal processor needs higher performance than 12.2kbps voice service when the 64kbps visual telephone service is provided, therefore mobile communication terminal is when providing the 12.2kbps voice service, its processor may operate in lower clock frequency, still can obtain satisfied communication effect.Operate under the lower situation in the sort processor clock frequency,, bring the prolongation of professional duration by the energy consumption that the supply power voltage that reduces processor just can be saved battery.
In the power conservation techniques of existing mobile communication terminal, people mainly realize the low-power consumption of terminal under holding state by use low-power consumption idle mode and sleep pattern, thereby prolong the stand-by time of terminal, and then prolong the professional duration of terminal.Usually, can deal with the miscellaneous service demand that it is supported in order to ensure mobile communication terminal, its processor operates on the higher clock frequency, has the high processing ability, the electric energy that corresponding consumption is more, this is a kind of great waste when it handles lower data amount business.For example, for the 12.2kbps voice service, from guaranteeing the angle of service quality, software in the mobile communication terminal only need be finished the Code And Decode of a frame voice data in 20ms, like that can just finish such computing in the time less than 5ms not reducing under the processor clock frequency situation processor.Because during mobile communication terminal call, if being changed to sleep pattern, its processor realizes that the low-power consumption of terminal is and difficulty, at this moment the high performance computation ability is provided is unnecessary to processor.And to keep the superior performance operational capability of processor, need higher clock frequency, and the peak value operating frequency of processor is proportional to its supply power voltage, thereby causes the waste of the energy content of battery.

Use the raising terminal traffic duration of the present invention method mobile communication terminal structural principle block diagram as shown in Figure 1.This mobile communication terminal is by constituting with lower unit: processor unit U1, clock generating unit U2, Power Management Unit U3, free time collecting unit U4, idleness computing unit U5 and performance synthesis control unit U6.
The concrete function of each several part is described as follows:
Processor unit U1: each task of carrying out mobile communication terminal device.
Clock generating unit U2: as input, generation and distribution normally move needed various clock signals for inner each unit of mobile communication terminal device with reference clock source C.The frequency of these clock signals (speed in other words) can be come change by the related register of software by configuration U2 inside, with clock signal that hope frequency is provided to corresponding hardware capability unit.In the present invention, utilize the inner relevant configuration register of clock generating unit U2 to come the clock frequency of processor controls.
Power Management Unit U3: by DC power supply V (being generally battery in handheld device), generation and distribution are for the needed various supply power voltages of the normal operation of mobile communication terminal device internal element.In these supply power voltages, some is fixed, and some then can come change by the related register that disposes U3 inside by software, to provide the supply power voltage of wishing voltage to corresponding hardware capability unit.In the present invention, utilize the related register of Power Management Unit U3 internal configurations to control the supply power voltage of supplying with processor.
