Description
Technical field
The invention belongs to wireless communication field, relate in particular to the method, system and device that base station performance detects in a kind of TDS-CDMA system.
Background technology
Perfect day by day along with base station functions in TD SDMA (TD-SCDMA) system, the performance of base station improves the emphasis that more and more becomes concern.On indoor test, need often every performance index of base station are detected, so that obtain the performance test results of base station and contrast, thereby reach detection, improve the purpose of the performance index of base station with simulation result under the reciprocity condition.
To make test condition as far as is humanly possible in the test, otherwise just may obtain performance test results not accurate enough even that difference is very big near simulated conditions.In order to make test condition near simulated conditions, need measure the test signal that signal source sends, if measurement result does not meet simulated conditions, then regulate test signal and continue and measure this signal, meet simulated conditions up to measurement result.
When detecting, base station performance sends test massage with signal source, the measurement of its time-domain position, generally can select frequency spectrograph class instrument to measure, the channel impulse response figure that is aided with base station general-utility test platform (GTS) observation signal in case of necessity is so that finely tuned position input signal; For the power measurement of signal, mostly adopt frequency spectrograph class instrument to carry out frequency domain measurement at present, to obtain input signal power value comparatively accurately.
The some signal source class instrument that need during the Performance Detection of base station, through linking to each other with the coupling disc inlet (generally selecting the single antenna inlet) of base station behind power splitter, the adjustable attenuator, test environment is built roughly can be as shown in Figure 1 usually.Why selecting single antenna inlet to connect and do not adopt power splitter to carry out many antennas to connect, is because signal has deviation through causing behind the power splitter between actual input value and the measurement input value.
Detect connection for base station performance shown in Figure 1, before testing, must measure at the signal value of coupling disc single antenna porch each instrument, during measurement coupling disc single antenna arrival line introduced frequency spectrograph class instrument, as shown in Figure 2, the test signal that then each signal source is sent is measured respectively.
Say in the strictness, if the input signal values of signal source has change, with regard to this signal is remeasured, but just need tear down and build link repeatedly and carry out the deletion sub-district owing to all measure at every turn, the deletion Radio Link, and set up the sub-district, set up Radio Link, send out multistep operations such as test post, and every Performance Detection comprises a plurality of measuring conditions, consider the complexity and the operability of practical operation, the general measuring process of simplifying that all adopts, be that each Performance Detection is only carried out signal measurement one time: the input show value of selected signal source (as-20dBm), measure its performance number with frequency spectrograph, this value is as the reference of other input signal values of signal calculated source, carries out addition calculation with the relative demonstration difference of signal source (promptly with-20dBm difference) and obtains signal input value.
After above-mentioned signal measurement work is finished, just can enter the performance detection-phase.Earlier test environment is built during Performance Detection to as shown in Figure 1, with corresponding signal source switch opens, send the analog signal of known power output, with test platform GTS login base station, issue corresponding test post, grasp the log file with main foundation as Performance Detection; The input value of regulating each signal source afterwards makes it to satisfy different test conditions, further repeats to grasp the operation of log file; At last each log file is carried out analytic statistics and obtain the result that base station performance detects.Here, preserve the interface message of inside of base station in the log file, comprise every performance index, be the interface message of inside of base station to be exported out, and be kept in the log file by testing tool.
Existing base station performance detection method adopts frequency spectrograph to carry out the signal subsidiary, and testing efficiency and test accuracy are low, mainly show the following aspects:
The undue frequency spectrograph that relies on when 1) base station performance detects, each test must wait frequency spectrograph to put in place, under the situation of p-wire frequency spectrum class instrument anxiety, be very limited, in addition,, the Performance Detection process tests repeatedly owing to often need contrasting simulation result, and general consuming time longer, taking frequency spectrograph class instrument in test process can't discharge, and can influence other test to a certain extent;
2) when signal source class instrument input signal values is measured, adopted and measured a certain reference point signal value and calculate the method for other input signal power value with this, make signal measurement have certain deviation, because even also can there be certain deviation in the signal measurement of single, adopt the mode of accumulation calculating can make this error reach (0.5dB, 0.5dB) scope sometimes.Add that signal value can have certain drift in time, this deviation influences the performance test results of base station sometimes to a great extent;
3) need split and to measure each signal source input signal values owing to the Performance Detection environment, unnecessary operation link when this has just increased Performance Detection, such as in the Performance Detection process, if desired signal input value being carried out to measuring, just need carry out the deletion sub-district earlier, remove operations such as link, connection frequency spectrograph, after measurement is finished, need to recover test environment again, set up the sub-district, send out test post etc. all kinds of, this artificial operation destroys original test environment sometimes to a certain extent, thereby influences the accuracy that base station performance detects;
4) in the Performance Detection to input signal values check and correction difficulty, can't the real-time monitored input signal values, lack and regulate flexibility.

Embodiment
In order to improve the efficient and the accuracy of the test of base station performance in the TD-SCDMA system, the embodiment of the invention provides the method that base station performance detects in a kind of TD-SCDMA system, and in this method, base station performance detects and is no longer dependent on frequency spectrograph and carries out signal measurement.
Referring to Fig. 3, the embodiment of the invention provides the method that base station performance detects in a kind of TD-SCDMA system, and its idiographic flow is as follows:
Step 301: when surveying the test signal that receives the signal source transmission, the test signal that receives is measured in the base station;
Step 302: measurement result and the test condition that sets in advance are compared, judge whether measurement result satisfies test condition,, then arrive step 304 if satisfy; Otherwise, to step 303;
Here, the simulated conditions that test condition is generally the base station when carrying out performance test also can be other conditions that set in advance.
Step 303: the test signal of sending is regulated according to test condition in the index signal source, returns step 301;
Here, the concrete grammar that the test signal of sending is regulated according to test condition in the index signal source can be: the index signal that will comprise amplitude of accommodation value sends to signal source, when signal source receives index signal, regulate according to the amplitude of accommodation value in this signal, for example, if amplitude of accommodation value be+5dBm, then signal source is with the power rise 5dBm of the test signal sent, if amplitude of accommodation value is-5dBm, then signal source is with the power decreasing 5dBm of the test signal sent.Can also be: the index signal that will comprise measurement result and test condition sends to signal source, when signal source receives index signal, measurement result in this signal and test condition are compared, how to determine conditioning signal, for example, if measurement result is 10dBm, and test condition is 15dbm, and then signal source is determined and the power of the test signal sent need be raised 15-10=5dBm.
Step 304:, obtain the base station performance testing result by the performance index of base station output are carried out analytic statistics.
In the step 304, can obtain the base station performance testing result by grasping the log file and the log file that grasps being carried out analytic statistics, can also adopt measuring instrument directly to measure, observe methods such as measurement reports from the IUB mouth, IUB is the interface between base station and the base station controller.These different modes are often at different performance tests.
Concrete, the base station is divided into two kinds of situations to the test signal measurement that receives in the step 301: the measurement when measurement when test signal is the full time slot signal and non-full time slot signal.
Wherein, for test signal is the situation of full time slot signal, can adopt the method for time slot received bandwidth total power (RTWP) measurement to the power measurement of full time slot signal, RTWP is the summation of the power of interior noise of the interior received pulse formed filter bandwidth of certain time slot and useful signal, public-measurement can be initiated in base station in the TD-SCDMA system after setting up the sub-district, utilize the training sequence code (MIDAMBILE) of receiving slot to come the RTWP value of signal calculated.For changes in distribution in time slot comparatively uniformly useful signal or noise it can measure comparatively accurately.For the TD-SCDMA system, even have only a user in the time slot, the useful upward signal that signal source simulation sends also takies whole time slot, utilizes the public-measurement of base station self to report RTWP can accurately measure and need not frequency spectrograph it fully; Equally, the simulating the white noise signal that sends for signal source also can utilize RTWP accurately to measure.Though the method that adopts RTWP to measure is simple, but because it is to utilize the MIDAMBILE sign indicating number of time slot partly to go to estimate the integral body of time slot, therefore be not that all signals can accurately be measured, when the part that just takies certain time slot in measured signal is non-full time slot signal, when especially haveing nothing to do with the MIDAMBILE sign indicating number, measured value has very large deviation, such as, for uplink synchronous (sync_ul) signal of reprovision to time slot 1 or time slot 2, owing to a part that just takies time slot and uncorrelated mutually, can't accurately measure with RTWP with MIDAMBILE sign indicating number part.
Because the time-domain position width of full time slot signal is known (the white noise bandwidth guarantees enough can need not greatly to measure), so the channel impulse response figure that only need utilize the GTS observation signal is to observe adjusting get final product to position input signal.
For test signal is the situation of non-full time slot signal, non-full time slot signal enters from the radio frequency mouth of base station, become the digital processing unit (DDP) that baseband signal enters baseband processing unit (BBU) through processing such as radio frequency unit (RFU) frequency band transformation, modulus (A/D) conversion, digital signal to DDP output is utilized related operation, detects and obtains the starting and ending position of signal on time slot.Range value for useful signal in initial, the end position of the signal window of determining test signal and the signal window, take bigger time domain measurement scope, time domain measurement scope before the signal window original position is referred to as (signal) front window, time domain measurement scope after the signal window end position is referred to as (signal) rear window, as shown in Figure 4.The position probing concrete grammar of test signal is: the power that calculates each power points in the time domain scope of test signal place, determine the position of front window, signal window and the rear window of test signal in its time domain scope according to the power of each power points, such as, the power points that performance number is undergone mutation for the first time is as the original position of signal window, this original position is the original position of test signal, the power points that performance number is undergone mutation for the last time is as the end position of signal window, and this end position is the end position of test signal.Time domain scope before the signal window is the front window of signal, and the time domain scope after the signal window is the rear window of signal.Then, calculate the average power of the power points of test signal in its front window and rear window, obtain noise or interference power; Calculate the average power of the power points of test signal in its signal window, this power deducts described noise or interference power, obtains the power of test signal.
After measuring the position or performance number of test signal, can adopt numerical value to report or the form of drawing is come out the position display of signal, so that carry out position adjustments; Or adopt numerical value to report or the form of drawing shows performance number, so that carry out power adjustments.Adopt this simple mode just can measure the position and the power of test signal, this measurement can the form with issuing message open or close in needs.The realization of this measurement need not existing hardware is done any change, on software is realized also is simple possible, only need certain algorithm and report trigger mechanism just can realize fully, its realization on base station testing instrument GTS also is simple, does not relate to more change.
