Description
Technical field
The present invention relates to a kind of radio terminal performance test device, particularly a kind of dut terminal can be operated under single or many network condition and reduce the radiation of test and the radio performance of terminal testing apparatus of the repeatability that raising is tested; The invention still further relates to a kind of radio terminal performance test method, particularly a kind of radio terminal performance test method that the test environment of dut terminal can be controlled, reduce the repeatability of testing radiation and raising test belongs to wireless communication technology field.
Background technology
Along with development of wireless communication devices and universal, mobile phone has become the mobile message center of daily life.Standby and air time are the technical indicators that mobile phone, operator and ordinary consumer are concerned about.General stand-by time=battery capacity/standby current; Air time=battery capacity/audio-frequency current; Video call time=battery capacity/video call electric current.Battery capacity generally is relatively more fixing; Standby current, audio-frequency current, video call electric current all belong to the power consumption index.Most energy of power consumption finally all will be transformed into heat, and along with the appearance of 3G technology, the cell-phone heating problem is universal day by day, therefore, how mobile phone are carried out effective power consumption control, reduces the important technology index that heating becomes mobile phone research and development or test.
In existing power consumption and the heat test, mainly contain following two kinds of test modes:
One, power consumption test schematic diagram as shown in Figure 1, anolog base station A is connected with mobile phone by radio frequency cable, different received signal intensity or designated mobile phone transmitting power are provided, mobile phone with false battery is connected with stabilized voltage power supply C, mobile phone is provided with shielding box B outward, stabilized voltage power supply C is by general-purpose interface bus (General Purpose Interface Bus, abbreviation GPIB) cable is connected with computer, by the computer monitor record current, by the current curve statistical value in the certain hour, in conjunction with the voltage of stabilized voltage power supply, can calculate power consumption mean value; Heat test schematic diagram as shown in Figure 2, similar with the method for testing among Fig. 1, just stabilized voltage power supply C is changed to multichannel point temperature meter D, the mobile phone of charged pool is connected with multichannel point temperature meter D by thermocouple, multichannel point temperature meter D is connected with computer by Serial Port Line/netting twine, by computer monitor record temperature, hot property is tested.
In realizing process of the present invention, the inventor finds first kind of test mode, and there are the following problems at least: first kind of test mode test environment is easy to control, but test be wired power consumption and heating index.The actual power loss and the hot property of mobile phone are wireless index, this test mode is not considered the influence of wireless indexes such as antenna efficiency, also can't assess the influence of the disturbing factor in the actual environment for use, even the wired power consumption of different mobile phones is identical with heating index, but in actual use, under the identical network signal strength signal intensity, very big difference may appear in power consumption and heating.
Two, Fig. 3 and Fig. 4 are existing second kind of test mode, the difference of this mode and first kind is: adopt anolog base station or existing now network (as the CDMA2000 of UNICOM network, China Mobile GSM global mobile communication net), with the testing mobile phone E of false battery and anolog base station/existing network A ' by wireless connections, the testing mobile phone F of charged pool links to each other with multichannel point temperature meter D, and added other mobile phone E ' as interference source, the radio power consumption of testing mobile phone and hot property, wherein, hot property comprises Temperature Distribution, temperature rise absolute value and temperature rise speed etc.
In realizing process of the present invention, the inventor finds second kind of test mode, and there are the following problems at least: though second kind of test mode overcome the deficiency of first kind of mode, can test wireless index, but still have following defective: (1) how under effects, signal strength signal intensity and transmitting power that mobile phone receives can't accurately be controlled, and the test result of different location does not have comparativity; (2) extraneous other interference (as daytime, the different time sections in evening, different weather conditions etc.) is uncontrollable, and the test that the antenna that links to each other with anolog base station is done is near-field test, and it is repeatable relatively poor that uncontrollable disturbing factor can cause testing; (3) during the high-power emission of mobile phone, big to human body radiation harm, healthy unfavorable to the tester; Owing to be subjected to the influence of external condition, bigger difference may appear to this mode in test result under identical transmitting power, and is repeatable poor, and test result only is reference, can't be as research, and test and test stone.
