Embodiment
The embodiment of the present invention provides a kind of testing equipment decay switching stitching error to determine method and apparatus, carry out the power adjustment by control terminal, make terminal after carrying out testing equipment decay switching, obtain the second moment point that the first moment point terminal power value front with switching is identical, thereby the difference of the power measurement values that definite testing equipment decay switching stitching error is the second moment point and the power measurement values of the first moment point, owing to having obtained testing equipment decay switching stitching error, so can adjust terminal closed-loop power control test result according to testing equipment decay switching stitching error, when being tested, considered the testing equipment decay switching stitching error brought while carrying out testing equipment decay switching, and then improved the accuracy of test.
As shown in Figure 2, the testing equipment decay switching stitching error that the embodiment of the present invention provides determines that method comprises:
Step S201, determine performance number and the power measurement values of first moment point of terminal before testing equipment decay switching instant;
Step S202, after testing equipment decay switching, the second moment point after adjusting the power of terminal and determining testing equipment decay switching instant, make terminal identical with the performance number of the first moment point in the performance number of the second moment point;
Step S203, determine the power measurement values of the second moment point, and the difference of the power measurement values of definite testing equipment decay switching stitching error power measurement values that is the second moment point and the first moment point.
Owing to carrying out testing equipment decay switching front and back, respectively get a moment point that the terminal power value is identical, and obtain by the power measurement values of the first moment point and the second moment point the testing equipment decay switching stitching error that testing equipment decay switching brings, and then can adjust terminal closed-loop power control test result by this testing equipment decay switching stitching error, avoid the impact of testing equipment decay switching stitching error on terminal closed-loop power control test result, improve the measuring accuracy of terminal closed-loop power control test, certainly, when carrying out other test, if need to carry out testing equipment decay switching, also can obtain the testing equipment decay switching stitching error that testing equipment decay switching brings by the method, and then carry out the adjustment of test result, in embodiments of the present invention, the terminal closed-loop power control of take test describes as example.
Testing equipment in the embodiment of the present invention can be comprehensive tester, can be also that other have the testing equipment of carrying out the closed-loop power control test; The value that during power measurement values, testing equipment is measured terminal power.
In order to calculate testing equipment decay switching stitching error in test process, and revise test result, need to measure the equal-wattage value under two kinds of evanescent modes of UE at receiver before and after splice point, thereby obtain power measurement values.Due in TD-SCDMA uplink power control scheme, the operation that does not make UE power keep, the operation of only having UE power to raise or lower, therefore need by first raising afterwards and lower, or first lower the mode raised afterwards UE power is remained unchanged.
Now, in step S202, after testing equipment decay switching, adjust the power of terminal, specifically comprise:
When carrying out power decreasing, make terminal carry out after power decreasing the first step-length to carry out power and raise the second step-length, and make terminal carry out after power raises the second step-length to carry out power decreasing the second step-length, wherein, second step length is more than or equal to the first step-length;
Carrying out timing on power, make terminal carry out after power raises the first step-length and carry out power decreasing the second step-length, and after making terminal carry out power decreasing the second step-length, execution power is raising the second step-length, wherein, second step length is more than or equal to the first step-length.
Simultaneously due to the implementation difference of each terminal when carrying out the power adjustment, when upper adjusting power or lower adjusting power, its entry-into-force time point may there are differences, such as some terminal realizes the power adjustment in next subframe that receives power adjustment commands, at next the subframe power that receives power adjustment commands, be that capable of regulating is complete, some terminal realizes the power adjustment in lower two subframes that receive power adjustment commands, at the lower two subframe power that receive power adjustment commands, just adjusts complete.Therefore, the second moment point of selected the second step-length and selection can compatible these two kinds of power to adjust schemes better.
When specifically carrying out power adjustments, also need the mode of carrying out the power adjustment according to terminal to carry out issuing of power adjustment commands, concrete, when terminal when next subframe that receives power adjustment commands realizes that power is adjusted, in step S202, the power of adjusting terminal is specially: transmitted power adjustment order after the last power adjustment commands of terminal is finished;
When terminal, when lower two subframes that receive power adjustment commands realize that power is adjusted, in step S202, the power of adjusting terminal is specially: in the last subframe transmitted power adjustment order that is finished of the last power adjustment commands of terminal.
In fact, in terminal when next subframe that receives power adjustment commands realizes that power is adjusted, the second step-length equals the first step-length can obtain the moment point that performance number is identical with the performance number of the first moment point, when but terminal realizes that in lower two subframes that receive power adjustment commands power is adjusted, possible terminal is before carrying out the first step-length adjustment, it is identical with the adjustment direction of the first step-length that it adjusts direction, be all to raise or be all to lower, the second step-length must be greater than the first step-length and could obtain the moment point that performance number is identical with the performance number of the first moment point so.
