Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
As shown in Figure 1, Fig. 1 is the applied environment schematic diagram of mobile phone transmission power rollback system of the present invention.In the present embodiment, described mobile phone 1 is connected with charging device 5, described mobile phone transmission power rollback system 11 runs in mobile phone 1, for receiving the power level that base station 4 sends to mobile phone, and the transmitting power of mobile phone 1 is return back to the corresponding transmitting power of described other next stage of mobile phone transmission power level.
Described mobile phone 1 also comprises memory 2 and processor 3.Described base station 4 is public mobile communication base station, it is a kind of form of radio station, refer in certain area of radio coverage, pass through mobile switching center, and the transceiving letter radio station of carrying out information transmission between mobile phone 1, described base station 4 is for notifying mobile phone 1 to communicate required power level in certain area of radio coverage.
The corresponding mobile phone transmission power of mobile phone transmission power rank described in each, described mobile phone transmission power is for maintaining communicating by letter of mobile phone 1 and 4 of base stations.Each mobile phone transmission power and a digital to analog converter (DAC, Digital to Analog Converter) magnitude of voltage are corresponding.Described DAC magnitude of voltage is that the digital signal Vramp being sent by CPU is converted to through digital to analog converter.Mobile phone transmission power is controlled by DAC magnitude of voltage and supply voltage, and supply voltage is constant.Therefore, the transmitting power of change mobile phone only need change DAC magnitude of voltage.The corresponding form of described mobile phone transmission power rank, mobile phone transmission power and DAC magnitude of voltage is stored in the memory 2 of mobile phone 1.In the present embodiment, as shown in Figure 4, be the mobile phone transmission power schematic diagram corresponding with DAC magnitude of voltage.
When mobile phone 1 is during in charged state, also can be to radio frequency (RF when charging device 5 provides charging voltage, Radio Frequency) RF transmitting provides voltage, the power output that can cause like this mobile phone increases, and described mobile phone power output comprises the charge power that mobile phone transmission power and charging cause.Generally, the charge power that charging causes is generally the power of 2 unit left and right.Therefore, when mobile phone 1 is when charging, for mobile phone can not increased because of the power output of mobile phone and cause that part index number is as mobile phone adjacent channel leakage ratio ACLR (Adjacent Channel Leakage Ratio), frequency spectrum, deterioration such as spuious grade, the power level of mobile phone 1 can be carried out to rollback, the interference of minimizing to other cellphone subscriber, nor can affect the proper communication between mobile phone 1 and base station 4.Concrete steps will be in subsequent detailed.
As shown in Figure 2, be the functional block diagram of mobile phone transmission power rollback system of the present invention.In the present embodiment, described mobile phone transmission power rollback system 11 comprises judge module 111, receiver module 112, searches module 113 and Executive Module 114.The alleged module of the present invention has been the program segment of a specific function, than program, is more suitable in describing the implementation of software in processor 3, about the function of each module, will in the flow chart of Fig. 3, specifically describe.
As shown in Figure 3, be mobile phone transmission power backing method of the present invention the flow chart of preferred embodiment.According to different demands, in this flow chart, the order of step can change, and some step can be omitted.
Step S11, whether judge module 111 selects " charging " option to judge that whether mobile phone 1 is in charged state in user interface according to user.When user selects " charging " option in user interface, mobile phone 1, when charged state, performs step S12; When user does not select " charging " option in user interface, mobile phone 1 is not when charged state, and this flow process finishes.
Step S12, receiver module 112 receives the power level that base station 4 sends to mobile phone.In the present embodiment, the power level sending as base station is 8, the transmitting power Wei14Ge unit of these power level 8 correspondences, DAC magnitude of voltage Wei85Ge unit.
Step S13, searches module 113 and in corresponding form, searches the corresponding DAC magnitude of voltage of described other next stage of mobile phone transmission power level.Described corresponding form is located in memory 2 for preserving the corresponding relation of mobile phone transmission power rank, mobile phone transmission power and DAC magnitude of voltage.In the present embodiment, described other next stage of mobile phone transmission power level is 9, the corresponding transmitting power of this mobile phone transmission power rank 9 Wei12Ge unit, DAC magnitude of voltage Wei69Ge unit.
Step S14, Executive Module 114 is carried out this DAC magnitude of voltage to control mobile phone transmission power according to the corresponding DAC magnitude of voltage of described other next stage of mobile phone transmission power level of searching.
By the present invention, when mobile phone 1 is during in charged state, in order to allow mobile phone can not cause because the power output of mobile phone increases that part index number, as ACLR, frequency spectrum and the deterioration such as spuious, can carry out the transmitting power of mobile phone 1 rollback, reduce the interference to other cellphone subscriber.
Finally it should be noted that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technical scheme of the present invention, and not depart from the spirit and scope of technical solution of the present invention.
