2) the current standing-wave ratio test of whether carrying out is detected in the base station
Enter the station as the people and to test or base station when testing automatically, the signal of standing-wave ratio test can be carried out in the base station, if carrying out the standing-wave ratio test, then return the signal of " test starts " and continue ongoing standing-wave ratio test to network management unit, if the current standing-wave ratio of not carrying out is tested, then carry out next step.
Above-mentioned steps 2) be optionally, in some cases, for example initial testing the time, the direct execution in step 3 of this step also can be crossed in the base station).
The legitimacy of 3) validation test parameter
Test parameter comprises test signal frequency, test signal power, testing time, test channel number etc., the checking content can comprise whether the test signal frequency belongs to the scope of test channel, whether the test signal performance number is in the scope that equipment allows, whether the testing time is reasonable, and whether the base station has test channel number pairing passage etc.; The scope of these parameters can be stored in the base station control unit in advance, is illegally if parameter exceeds predetermined range, can send warning or reset parameter etc. voluntarily.
Above-mentioned steps 3) be optionally, promptly can to give tacit consent to above-mentioned test parameter all be legal in the base station.
4) detect test channel whether normal talk business is being provided
Whether open by power amplifier and to judge whether test channel exists normal talk business, if power amplifier is opened, then there is normal talk business in expression, and the frequency of current talk business is removed in the base station, and is this channel arrangement test signal frequency (being generally default test frequency); If power amplifier is not opened, then direct configuration testing signal frequency point (being generally default test frequency).
Above-mentioned steps 4) be optionally, for example when initially opening the station, the base station can directly configure the test signal frequency.
Obviously, only otherwise influence the realization that standing-wave ratio is tested, above-mentioned steps 1)-4 the order) can be carried out multiple conversion, for example, can detect current whether carrying out earlier and determine test parameter again after the standing-wave ratio test, or can verify to detect again after the legitimacy of test parameter currently whether carrying out the standing-wave ratio test earlier, or can detect test channel earlier whether certificate parameter legitimacy more is being provided after the normal talk business.
5) test channel begins according to the test parameter emissioning testing signal
The test channel of base station begins according to the test parameter emissioning testing signal, and it is preferably at default test frequency and begins to launch tone signal with maximum power, and the pattern of tone signal is a single carrier.This test signal is exclusively used in test, need not specially be received.Use the test signal of this method can reduce the influence of extraneous factor and equipment to greatest extent, guarantee the accuracy of test test result.
6) send the disabled signal of channel resource state
Behind the beginning emissioning testing signal, the RF remote processing unit is to baseband processing unit (BBU, Base Band Unit) report the channel resource state unavailable, the baseband processing unit sub-district is set to unavailable, no longer accept normal talk business to guarantee the base station, can prevent each interchannel phase mutual interference like this, guarantee the accurate of test result; For Multi-Mode Base Station, the test channel resource status need be reported to whole baseband processing unit (for example, the baseband processing unit of the baseband processing unit of GMS and WCDMA).
Above-mentioned steps 6) is optionally, promptly also can not report the channel resource state unavailable, and when test, still allow other passage of base station to accept normal talk business (this moment, test accuracy was poor slightly, but littler to the influence of regular traffic).
7) start the standing-wave ratio test
Start the standing-wave ratio test, open power amplifier, relevant devices such as RF remote processing unit enter test mode; Wherein standing-wave ratio test can postpone to restart in 3 seconds after test signal begins emission, to guarantee stablizing of described test signal.
8) after starting the standing-wave ratio test, statistics backward power and forward power
Be preferably average backward power and average forward power in the statistical test time, and (just from beginning emissioning testing signal after coextensive slow 5 seconds) begins to add up performance number more preferably to postpone 2 seconds again after starting the standing-wave ratio test, further to guarantee the stable of test result; Once current backward power and the forward power of wherein every 100ms statistics, and with the statistics performance number be stored in the base station control unit, finish up to the testing time, base station control unit is obtained the mean value of the many groups power that records in the testing time afterwards, as the average backward power in the testing time and the result of forward power; For example, the testing time is 10 seconds, then obtains 101 backward power values and 101 forward power values in the testing time altogether, and the mean value of all backward power values is average backward power, and the mean value of all forward power values is average forward power; Obviously, the mode of averaging after this repeatedly statistics can improve test accuracy.
9) stop the reverse and forward power of statistics
After testing time arrived, EOT stopped the reverse and forward power of statistics, stops emissioning testing signal, made test channel recover the frequency of regular traffic (i.e. the operation frequency of the talk business before the test beginning), pass power amplifier.
Optionally, if reported the channel resource state unavailable to baseband processing unit before, then report the channel resource state to use to baseband processing unit again, the baseband processing unit sub-district is set to available, and the base station begins to continue to accept normal talk business again; If Multi-Mode Base Station, then the channel resource state need report whole baseband processing units.
10) calculate standing-wave ratio according to backward power and forward power
Standing-wave ratio can be calculated by following formula:
Standing-wave ratio=(average forward power
1/2+ average backward power
1/2Average forward power of)/(
1/2-average backward power
1/2).
Obviously, only otherwise the realization of influence test, those skilled in the art also can carry out many variations to the method for testing standing-wave ratio of the foregoing description, for example, if detect the current standing-wave ratio test carried out, also can stop current ongoing test and carry out the test of present embodiment.
