Before the collection feedback channel data of acquisition module 301, acquisition module 303 is opened for obtaining master control Dynamic offline DTP instructions, and master control is started into offline DTP instruction be supplied to pause module 304, wherein, master control starts the configuration frequency at least including feeder line in offline DTP instructions, the tested length of feeder line, feeder line description information, feedback channel mark and receiving channel mark.

The configuration frequency of feeder line includes the initial frequency of feeder line and the termination frequency of feeder line.

Suspend module 304, it is legal for starting the information in offline DTP instructions when master control, and when testing the highest priority of the offline DTP instructions of master control startup in the business of mutual exclusion with DTP, suspend the processing of other business datums, and inform paused other business datums of processing of starting module 305, other business datums include less than DTP test prioritizations and data corresponding with the business that the DTP tests mutual exclusion, and DTP tests the position for fault inspecting.

After pause module 304 suspends the processing of other business datums, starting module 305 starts DTP tests.

It is appreciated that, starting module 305 is before DTP tests are started, whether the information that the verification master control of correction verification module 313 starts in offline DTP instructions is legal, when whether the information that master control starts in offline DTP instructions is legal, pause module 304 judges to test same priority and/or the mutual exclusion business higher than DTP test prioritizations with DTP（The business of mutual exclusion is tested with the DTP）Whether it is carrying out.I.e.：It is carrying out when there is the mutual exclusion business with DTP test same priorities and/or higher than DTP test prioritizations（The priority that i.e. master control starts offline DTP instructions is not highest）When, then completed when with DTP test same priorities within the wait scheduled time and/or higher than the business processing of DTP test prioritizations, suspend the business that mutual exclusion is tested in the pause of module 304 less than DTP test prioritizations and with the DTP, then inform that starting module 305 is paused and handle other business datums, so that starting module 305 starts the business of DTP tests；When the business with DTP test same priorities and/or higher than DTP test prioritizations within the wait scheduled time does not handle completion, starting module 305 does not start DTP tests.It is understood that the wait scheduled time is used to etc. pending to test same priority and/or the business hours higher than DTP test prioritizations with DTP.The present invention does not limit the specific time range for waiting the scheduled time, such as 5s.

When being carrying out in the absence of the mutual exclusion business with DTP test same priorities and/or higher than DTP test prioritizations, pause module 304 directly suspends the processing of other business datums, and starting module 305 starts DTP tests. Further, after starting module 305 starts DTP tests, initialization module 306 is initialized respectively to RAM modules 310 and FDR modules 302.And state-query module 307 carries out status inquiry to RAM modules 310 and FDR modules 302 respectively, and the Query Result of RAM module 310 and FDR modules 302 is sent to termination module 308.

Wherein, data generating module 309, generate at least one set of swept-frequency signal, and at least one set of swept-frequency signal is pre-stored in RAM module 310 for starting the information in offline DTP instructions according to master control.

When data generating module 309 generates at least two groups of swept-frequency signals, there is the interval of same time, i.e. data generating module 309 periodically generation swept-frequency signal between every group of swept-frequency signal.

Specifically, the tested passage feedback channel that data generating module 309 starts offline DTP instructions according to control and included identifies corresponding feedback channel, receiving channel identifies the information of corresponding receiving channel, at least one set of swept-frequency signal is produced, and every group of swept-frequency signal is delivered in RAM module 310 by local bus local bus.

RAM module 310, at least one set of swept-frequency signal produced for pre-stored data generation module 309.Module 308 is terminated, for continuous-query to be arrived in the first pre-determined number when state-query module 307

When the state of RAM module 310 and at least one module in FDR modules 302 is unavailable, terminate

DTP is tested.

The present invention do not limit the concrete numerical value of the first pre-determined number, and the priority tested according to DTP determines the concrete numerical value of the first pre-determined number.For example when the priority for setting DTP to test in a base station is higher, the value of the first pre-determined number is larger.Such as 3 times, 4 times or 5 times.When the priority for setting DTP to test in a base station is relatively low, the value of the first pre-determined number can be 1 time or 2 times.

What deserves to be explained is, meet the regulation for performing DTP tests, it is necessary to be checked whether to the processing DTP correlation modules for testing corresponding business datum after starting module 305 starts DTP tests.Assuming that the first pre-determined number is three times, after state-query module 307 is inquired about RAM module 310 and FDR modules 302, it was found that the state of FDR modules 302 (or FDR modules 302 and RAM module 310) is unavailable, then state-query module 307 carries out the inquiry of state to FDR modules 302 again（Or state-query module 307 carries out the inquiry of state to RAM module 310 and FDR modules 302 again）. After state-query module 307 is inquired about three times, when the state of FDR modules 302 is still unavailable, reporting module 314 reports the first failed message of DTP test executions failure to module 308 is terminated, and the error code of first failed message fails for the application of FDR modules.Terminate module 308 and terminate DTP tests；Reporting module 314 reports resource available message to starting module 305 simultaneously, and the resource available message is used for the processing operation for indicating that starting module 305 starts other business datums, so that other business datums can proceed processing.

Similarly, when state-query module 307 inquire the state of RAM module 310 and/or FDR modules 302 for it is unavailable when, the error code of the first failed message can be that RAM module and/or the application of FDR modules fail.Explanation is needed further exist for, the configuration frequency of feeder line includes initial frequency, the termination frequency of feeder line of feeder line.

Master control is started the information in offline DTP instructions after the offline DTP instructions of master control startup are obtained, also and is supplied to enable module 311 and configuration module 312 by acquisition module 303.

Module 311 is enabled, is enabled for testing corresponding feedback channel, receiving channel, RAM module 309 to DTP.Wherein, enable module 311 to start the corresponding feedback channel of feedback channel mark selection in offline DTP instructions according to master control and enable, the receiving channel mark started in offline DTP instructions according to master control selects corresponding receiving channel and enabled.And enable module 311 is enabled to RAM module 310.

Configuration module 312, for the initial frequency according to feeder line and the termination frequency configuration local frequency of feeder line.The configuration frequency that wherein configuration module 312 starts feeder line in offline DTP instructions according to master control configures local frequency.Further, after FDR modules 302 obtain result of calculation, correction verification module 313 is needed to carry out result of calculation legitimacy verifies, and check results are supplied into reporting module 314 and module 308 is terminated.

When check results are that result of calculation is legal, reporting module 314 externally reports result of calculation；When result of calculation is illegal, reporting module 314 externally reports the delayed filing request that DTP is tested, and delayed filing request is supplied into acquisition module 301 and FDR modules 302, so that acquisition module 301 is adopted again Collect new feedback channel data and new receiving channel data, and it is supplied to FDR modules 302 to reacquire the corresponding new result of calculation of DTP tests new feedback channel data and new receiving channel data, delayed filing request handles the request of the corresponding result of calculation of DTP tests for instruction again.

It is understood that after FDR modules 302 regain new result of calculation, it is still desirable to which the new result of calculation of 313 pairs of correction verification module carries out legitimacy verifies.

Whether legitimacy verifies can meet pre-provisioning request etc. including SNR.

When it is illegal that check results, which are the new result of calculation that is continuously acquired in the second pre-determined number, reporting module 314 reports the second failed message of DTP test executions failure to module 308 is terminated, and the error code of second failed message is illegal for result of calculation.Terminate module 308 and terminate DTP tests.

It is understood that the second pre-determined number is not also limited by scope in the present invention.In this programme, the description for the second pre-determined number refers to the description to the first pre-determined number.

Explanation is needed further exist for, after configuration frequency that above-mentioned modules obtain feeder line corresponding result of calculation, if still suffering from other frequency sub-band needs to carry out the detection of trouble point（DTP is tested）When, the modules in device 30 continue to perform the associative operation of DTP tests to obtain the corresponding result of calculation of other frequency sub-band.

What deserves to be explained is, it is present in the modules that device 20 and/or device 30 include in Remote Radio Unit (Radio Remote Unit, RRU).

Pass through this programme, while the efficiency of fault inspecting is improved, it is the problem of base station, upper wire jumper, lower wire jumper and/or antenna break down that deduction is only capable of in compared with prior art, the present invention is by frequency domain point except method calculates the reflection delay time of trouble point, according to the reflection delay time of trouble point, trouble point is obtained to the distance eated dishes without rice or wine, so as to be accurately obtained the position of trouble point.With reference to the description in Fig. 3-Fig. 4, the present invention provides a kind of processing method of signal, and the executive agent of this method can be base station, and specific is the RRU in base station.As shown in fig. 6, this method is specifically included：

601, feedback channel data are gathered, pre-distortion is carried out to feedback channel data, pre-distortion data are obtained, feedback channel data are the data of the active inter-modulated signal in feedback channel coupling firing passage. Wherein, transmission channel is the passage of active inter-modulated signal outwards launched, and feedback channel is the passage of the active inter-modulated signal in coupling firing passage.

602, receiving channel data are gathered, using pre-distortion data as reference data, PIM spectral lines are obtained from receiving channel data, receiving channel data are the data that receiving channel receives the signal that the passive intermodulation signal produced by trouble point and antenna are received.

Wherein, the passage for the signal that the passive intermodulation signal and antenna that receiving channel produces for reception by trouble point are received.

603, PIM spectral lines and base reference signal are subjected to frequency domain point except method calculates the position of trouble point, result of calculation is obtained, result of calculation includes trouble point to the distance eated dishes without rice or wine.

It can be the machine top opening end of transmitting swept-frequency signal wherein to eat dishes without rice or wine.

A kind of processing method of signal provided in an embodiment of the present invention, with needing artificial upper station in the prior art and being loaded by accessing low intermodulation, break down corresponding position progress downlink artificial load to base station, lower wire jumper, upper wire jumper, feeder line and antenna respectively, so as to the connection of investigation cable step by step, the problem of fault detection efficiency is relatively low is caused to be compared, the present invention obtains PIM spectral lines by gathering feedback channel data and collection receiving channel data, and according to feedback channel data and receiving channel data；Then PIM spectral lines and base reference signal are subjected to frequency domain point except method calculates the position of trouble point, result of calculation are obtained, result of calculation includes trouble point to the distance eated dishes without rice or wine, so as to improve the efficiency of detection failure.Further, pre-distortion data in step 601 are active inter-modulated signal.

In the present embodiment, the RRU of base station is generated and is periodically launched swept-frequency signal (ofdm signal to cable to be measured）.Because transmission channel has necessarily non-linear, cause active signal by the way that nonlinear active inter-modulated signal can be produced after transmission channel, in order to avoid the generation influence for the reflected signal that nonlinear active signal is produced on trouble point, cause the trouble point calculated incorrect, so needing to fall the active inter-modulated signal correction of transmission channel by feedback channel.In the delivery outlet of transmission channel（Transmitting（Transport, Tx) before duplexer）The radiofrequency signal of a part is coupled to feedback channel, the feedback channel data of collection are then subjected to pre-distortion. Further, in step 602, receiving channel data include the signal and other signals that trouble point is reflected.After transmission channel signal is by trouble point, it may occur that the broadening phenomenon of frequency spectrum, the inter-modulated signal partial frequency spectrum of broadening falls into the corresponding reception frequency range of receiving channel, drops into the signal meeting for receiving frequency range because reflexing to reception（Receive, Rx) duplexer is so as to fall into receiving channel, and after being received by receiving channel, receiving channel data are gathered, receiving channel data and pre-distortion data are then filtered frequency conversion, suppress non-intermodulation frequency signal（Namely active inter-modulated signal）, extract the PIM spectral lines needed.

That is, because passive intermodulation signal is used for the accurate location of fault inspecting, and active inter-modulated signal and passive intermodulation signal are included in receiving channel data.Therefore need the predistorting data to be obtained in step 601（Active inter-modulated signal）For reference data, frequency-conversion processing is filtered to receiving channel data, passive intermodulation signal, i.e. PIM spectral lines is obtained.

It is further to note that the feedback channel data gathered in the uniformity in order to ensure data, the present embodiment and the receiving channel data of collection are the signal in same group of swept-frequency signal.Further, in step 603, carry out the position that frequency domain point removes method trouble point, specifically including by PIM spectral lines and base reference signal：

\ _{Peak-\ N_f -\

In formula（1) in, L is trouble point in cable from eating dishes without rice or wine（Launch the machine top opening end of swept-frequency signal）Distance, Peak is the direct current signal that exports PIM spectral lines and base reference signal by frequency mixer through analog-digital converter（Analog to Digital Converter, ADC) after sampling, carry out the integer corresponding to the peak point that is obtained after FFT (Fast Fourier Transformation, FFT)； N_fftIt is the sampling number (generally 1024,2048,4096 etc. when carrying out FFT in a cycle）； _；For the initial frequency of swept-frequency signal； /₂For the termination frequency of swept-frequency signal；_PFor the wave velocity of swept-frequency signal.When swept-frequency signal frequency step for Δ/when, then ^=4； _/₂) (2) maximum fault measuring distance for being obtained using this method： 1^ = 4^ ( 3 ) Measurement accuracy is： M=~^V^L ( 4 )

^2Nffi

For example, being 21, N_fft^ 1024, the start-stop frequency of test is 1920 ~ 1980MHz, i.e. ,/;For 1920MHz ,/₂For 1980MHz.Swept-frequency signal（Ofdm signal）Frequency step be 1 Μ Η ζ.Calculated by above formula, trouble point L is 2.9 ± 0.146 meters.Current trouble point maximum measurement length ware is 120 meters, and in order to ensure the correctness of measurement, the value of system is 100 meters.So the scope of measured value normally should be within 0 ~ 100 meter.

It is assumed that the upper wire jumper of antenna-feedback system is 5 meters, lower wire jumper is 5 meters, a length of 90 meters of feeder line, and the connection of antenna feeder is as shown in figure 1, be then 2.9 meters according to result of calculation L above, then corresponding trouble point is on lower wire jumper.And eated dishes without rice or wine the position at 2.9 ± 0.146 meters in lower wire jumper distance.

Further desirable for explanation, PIM spectral lines include feedback channel data and receiving channel data --- the correspondence in the corresponding passive intermodulation signal of at least one set of swept-frequency signal, one group of swept-frequency signal.

Specifically in step 603：

When PIM spectral lines passive intermodulation signal corresponding including one group of swept-frequency signal, PIM spectral lines and base reference signal are subjected to frequency domain point except method calculates the position of trouble point, acquisition result of calculation.

At least one PIM spectral line is obtained after receiving channel data to be filtered to processing, RRU can therefrom extract multiple PIM spectral lines.It is preferred that, RRU extracts wherein one PIM spectral line.

When PIM spectral lines passive intermodulation signal corresponding including at least two groups swept-frequency signals, the corresponding passive intermodulation signal of every group of swept-frequency signal in PIM spectral lines is overlapped, obtain being superimposed PIM results, PIM results will be superimposed and carry out frequency domain point except method calculates the position of trouble point with base reference signal, result of calculation is obtained.As can be seen that by being overlapped to the corresponding passive intermodulation signal of at least two groups swept-frequency signals, the error rate of result of calculation can be reduced.Further, before step 601, this method can also include：

The offline DTP instructions of master control startup are obtained, at least configuration frequency including feeder line, the tested length of feeder line, feeder line description information, feedback channel is identified and receiving channel mark in the offline DTP instructions of master control startup.Information in the offline DTP of master control startup is instructed is legal, and the master control described in the business of mutual exclusion starts During the highest priority of offline DTP instructions, suspend the processing of other business datums and start DTP tests, other business datums include less than DTP test prioritizations and data corresponding with the business that DTP tests mutual exclusion, and DTP tests the position for fault inspecting.Wherein, the information that R U start to master control in offline DTP instructions, which carries out legitimacy verifies, includes the information and memory space during RRU instructs DTP（Such as RAM modules) in information be compared, when both information are consistent, illustrate that the information that master control starts during offline DTP is instructed is legal.

Wherein, it is what is issued by the BBU in base station that master control, which starts offline DTP instructions,.When BBU is received by the detection faulting instruction that the maintenance console of base station is issued, the configuration parameter included according to the detection faulting instruction starts offline DTP instructions to generate master control, and the offline DTP instructions of master control startup are passed into RRU.Detection faulting instruction is used to indicate that DTP tests are opened in base station.Detect that the configuration parameter in faulting instruction can include initial frequency, the termination frequency of feeder line, feeder line description information, the tested length of feeder line, transmission channel mark, feedback channel mark and receiving channel mark of configuration feeder line etc..

After RRU receives the offline DTP instructions of master control startup, before DTP tests are started, the legitimacy of the information in the offline DTP instructions of RRU verification master control startups.

When master control start the information in offline DTP instruction it is legal when, judge whether to have in the business handled the mutual exclusion business that service priority is tested higher than DTP.When there is the mutual exclusion business for being higher than DTP test service priority, when processing completes the mutual exclusion business that this is higher than DTP test service priority within the wait scheduled time, suspending the processing of other business datums and starting DTP and testing.When wait the scheduled time within still it is untreated complete this higher than DTP test service priority mutual exclusion business when, do not start the DTP test, that is, terminate the DTP test.When in the absence of the mutual exclusion business that service priority is tested higher than DTP, suspend the processing of other business datums and start DTP tests.

What deserves to be explained is, when RRU starts DTP tests, RRU deletes carried service district information, and externally reports resource unavailable.Here resource refers to the resource required for RRU processing business.

Same, the scope of the scheduled time is not limited in the present invention, the validity that usual scheduled time embodiment DTP is tested, under the premise of DTP tests are effective, RRU is just tested after can waiting the mutual exclusion business processing completion that service priority is tested higher than DTP to start DTP. Further, after RRU starts DTP tests, this method also includes：

RAM module and FDR modules are initialized and status inquiry respectively.When in the first pre-determined number continuous-query at least one module in RAM module and FDR modules state for it is unavailable when, terminate DTP test.Wherein, R U inquire about RAM module and the state of FDR modules is specifically included：RRU obtains the corresponding parameter for being used to detect of the corresponding parameter and FDR modules for being used to detect of RAM module, then the parameter for being used to detect of acquisition is contrasted with the predetermined standard value of corresponding RAM module and FDR modules, the corresponding parameter for being used to detect of parameter and FDR modules for being used to detect when RAM module is corresponding is consistent with corresponding predetermined standard value respectively, the state for illustrating RAM module and FDR modules is available, and vice versa.

RAM module is used at least one set of swept-frequency signal that prestores.FDR modules are used to obtain the position that the DTP tests corresponding trouble point.It is understood that RAM module and FDR modules are present in RRU.

The present invention do not limit the concrete numerical value of the first pre-determined number equally yet, and the priority tested according to DTP determines the concrete numerical value of the first pre-determined number.For example when the priority for setting DTP to test in a base station is higher, the value of the first pre-determined number is larger.Such as 3 times, 4 times or 5 times.When the priority for setting DTP to test in a base station is relatively low, the value of the first pre-determined number can be 1 time or 2 times.

Further, when R U in the first pre-determined number continuous-query to the state of RAM module and FDR modules be available when, corresponding feedback channel, receiving channel, RAM module are tested to DTP and enabled.According to the initial frequency of feeder line and the termination frequency configuration local frequency of feeder line.

After RRU configuration local frequencies, start to perform step 601.It is understood that the concrete operations that the operation that step 601- steps 603 are performed is tested for DTP.Further, after step 603, this method also includes：

Legitimacy verifies are carried out to result of calculation.When result of calculation is legal, result of calculation is externally reported.Externally the result of calculation is reported to be specially：RRU reports result of calculation to BBU, and BBU is reported in the equipment such as terminal again. What deserves to be explained is, when there are multiple frequency sub-band and need to carry out DTP tests, RRU can repeat to test corresponding result of calculation according to the DTP that above-mentioned steps obtain other frequency sub-band.

When result of calculation is illegal, the delayed filing request for externally reporting DTP to test, and the corresponding new result of calculation of DTP tests is reacquired, delayed filing request is the request for indicating the corresponding result of calculation of processing DTP tests again.

Specifically, delayed filing asks to be used to indicate that R U reacquire DTP and test corresponding new result of calculation.

When result of calculation is illegal, R U can repeat step 601- steps 603 in the second pre-determined number, and then obtain new result of calculation.

When the corresponding new result of calculation of DTP tests obtained in the second pre-determined number is legal, new result of calculation is externally reported.When the new result of calculation continuously acquired in the second pre-determined number is illegal, DTP tests are terminated.After RRU terminates DTP tests or terminates DTP tests, R U externally report resource can use, and recover the processing of other business datums.With reference to Fig. 6 and foregoing description, the present invention can also provide the processing method of another signal, as shown in fig. 7, this method includes：

701, BBU send master control to RRU starts offline DTP instructions.

Master control starts the configuration frequency at least including feeder line in offline DTP instructions, the tested length of feeder line, feeder line description information, feedback channel mark and receiving channel mark.

702, R U obtain master control and start offline DTP instructions.

703, R U detect that the master control starts the legitimacy of offline DTP instructions.

When the master control, which starts offline DTP, instructs legal, step 704 is continued executing with.When the master control, which starts offline DTP, instructs illegal, DTP tests are not started.

Optionally, RRU reports carrying master control to start offline DTP and instructs illegal message to BBU.

704, R U judge whether to have in the business handled the mutual exclusion business that service priority is tested higher than DTP.

When there is the mutual exclusion business higher than DTP test service priority, step 705 is continued executing with. When in the absence of the mutual exclusion business that service priority is tested higher than DTP, step 706 is continued executing with.
