Embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
The fault of antenna-feedback system has a variety of, and for example minizone master diversity reception antenna reversal connection, minizone reversal connection, antenna-feedback system interface become flexible, feeder line is aging etc.To different faults different fault detection methods is arranged, below specifically describe.
Embodiment one, specify referring to Fig. 1, Fig. 1 is the method flow sketch map of the embodiment of the invention one.
Steps A 1, obtain the main diversity antenna of the same antenna and the reception total power signal of inferior diversity antenna, wherein the number of time diversity antenna is at least one.
Receive total power signal and represent in the designated bandwidth, the intensity of the total power signal that receives, usually at-112dBm to-60dBm.
DBm is the value (also can think with 1mW power to be a ratio of benchmark) of an expression power absolute value, and computing formula is: and 10log (performance number/1mw).For example power P is 1mw, converts to being 0dBm behind the dBm.
The number of inferior diversity antenna can be for one or more, when the number of inferior diversity antenna when being a plurality of, can obtain the reception total power signal of each time diversity antenna.
The reception total power signal that steps A 2, basis get access to obtains the relation that main diversity antenna receives total power signal and arbitrary diversity antenna reception total power signal.
Can represent in several ways that main diversity antenna receives the relation of total power signal and arbitrary diversity antenna reception total power signal; For example: main diversity antenna receives the strength difference value of total power signal and arbitrary diversity antenna reception total power signal, and perhaps main diversity antenna receives the misrouting probability value of total power signal and arbitrary diversity antenna reception total power signal; Perhaps said main diversity antenna receives the relevance values of total power signal and arbitrary diversity antenna reception total power signal.
When the number of inferior diversity antenna when being a plurality of, can obtain main diversity antenna and receive the relation that total power signal and each time diversity antenna receive total power signal.
Steps A 3, confirm the testing result of antenna-feedback system according to the relation that obtains.
For example, if the main diversity antenna that obtains in steps A 2 receives relation that total power signal and arbitrary diversity antenna receive total power signal when being the strength difference value, strength difference value and strength difference threshold value are compared; When the strength difference value is higher than the strength difference threshold value, judge antenna-feedback system generation physical route fault.
If the main diversity antenna that obtains in steps A 2 receives relation that total power signal and arbitrary diversity antenna receive total power signal when being the misrouting probability value, misrouting probability value and misrouting probability threshold value are compared; When main diversity antenna reception total power signal is higher than the misrouting probability threshold value with time misrouting probability value of diversity antenna reception total power signal, judge that the antenna-feedback system generation divides the collection misconnection.
If the main diversity antenna that obtains in steps A 2 receives relation that total power signal and arbitrary diversity antenna receive total power signal when being relevance values, relevance values and correlation threshold value are compared; When main diversity antenna reception total power signal is lower than the correlation threshold value with time relevance values of diversity antenna reception total power signal, judge that the antenna-feedback system generation divides the collection misconnection.
When the number of inferior diversity antenna is a plurality of, then receive the relation of total power signal and each time diversity antenna reception total power signal, confirm the testing result of antenna-feedback system according to the main diversity antenna that obtains.
The embodiment of the invention can use ordinary terminal to test, and need not to employ special terminal and bigger human resources, and testing process is simple, and accuracy rate is high.Can judge timely and accurately that through the method for present embodiment the fault of which kind of type has taken place antenna-feedback system; Then can make fast reaction targetedly; Safeguard or debug, thereby guarantee the efficient normal operation of base station, guarantee the conveying quality of network signal.
Need to prove; Can there be a main collection and a plurality of the branch collection of dividing in antenna; The embodiment of the invention can be answered with each time branch set pair respectively leading the branch collection, obtains main diversity antenna and receives total power signal and time relation of diversity antenna reception total power signal, confirms the testing result of antenna-feedback system.The situation of a main Fen Ji and one branch collection is merely and illustrates in the following embodiment of the invention, should not be regarded as limiting.
Embodiment two, specify referring to Fig. 2, Fig. 2 is the method flow sketch map of the embodiment of the invention two.
Step 101: obtain the main diversity antenna of the same antenna and the reception total power signal of arbitrary diversity antenna.
The main diversity antenna of the same antenna and the reception total power signal of arbitrary diversity antenna can be recorded in two matrixes, the corresponding matrix of the reception total power signal of a diversity antenna.
Step 102:, obtain the strength difference value that main diversity antenna receives total power signal and arbitrary diversity antenna reception total power signal according to the reception total power signal that gets access to.
Strength difference value numerical value is bigger, explains that then the intensity of main diversity antenna reception total power signal and arbitrary diversity antenna reception total power signal has big difference, and then fault possibly take place the physical circuit of some diversity antennas.
The strength difference value can be represented in several ways; For example; Be divided by after can the numerical value in the reception total power signal matrix B of the reception total power signal matrix A of main diversity antenna and arbitrary diversity antenna being averaged respectively; Merchant's absolute value is carried out arctangent cp cp operation, multiply each other with half of circumference ratio again, then obtain main diversity antenna and receive the strength difference value that total power signal and time diversity antenna receive total power signal.
Specifically can calculate the strength difference value that main diversity antenna receives total power signal and arbitrary diversity antenna reception total power signal: P=ATAN{abs [avg (A)/avg (B)] through following formula } * pi/2 * 100%; Wherein, A and B are the main diversity antenna of the same antenna and the reception total power signal matrix of arbitrary diversity antenna; Be divided by after numerical value in the reception total power signal matrix B of the reception total power signal matrix A of main diversity antenna and time diversity antenna averaged respectively; The absolute value of getting the merchant carries out arctangent cp cp operation, and multiplying each other with half of circumference ratio is scaled percentage and then obtains the strength difference value again.
For example, main collection and the inferior reception total power signal of collection that divides of dividing that gets access to differs one times, and promptly A=2B can learn that according to formula the strength difference value is 70% so.For avoiding the data network causes on average during the spare time after inaccurate, can the reception total power signal that obtain under the antenna-feedback system no-load condition be removed, obtain the reception total power signal matrix A of period outside the antenna-feedback system zero load ' and B ', corresponding formulas then is:
P＝ATAN{abs[avg(A′)/avg(B′)]}*π/2*100％。
Step 103: strength difference value and strength difference threshold value that the main diversity antenna that will obtain receives total power signal and arbitrary diversity antenna reception total power signal compare, and when being higher than the strength difference threshold value, judge antenna-feedback system generation physical circuit fault.
The strength difference threshold value can be provided with according to actual environment flexibly; Can the strength difference threshold value turned down when higher the cell data quality requirement; When the cell data quality requirement is relatively hanged down, the strength difference threshold value is heightened, do not influenced the realization of the embodiment of the invention.
For example, 70% comparing with pre-configured strength difference threshold value with what step 102 calculated, be during greater than 70% value in pre-configured strength difference threshold value, and the current operation of judgement antenna-feedback system is normal; In pre-configured strength difference threshold value is during less than 70% value, judges the current physical circuit fault that taken place of antenna-feedback system.
Need to prove; Also can represent that main diversity antenna receives total power signal and time strength difference value of diversity antenna reception total power signal through other modes; For example, main diversity antenna being received total power signal and time diversity antenna receives total power signal and subtracts each other and obtain difference, this difference table degree of expressing strong difference value; Then at this moment, also corresponding the changing of strength difference value threshold value of presetting.
In addition; When more than one of inferior diversity antenna; Can obtain the strength difference value that main diversity antenna receives total power signal and each time diversity antenna reception total power signal respectively; Compare with the strength difference threshold value respectively, when arbitrary strength difference value is higher than the strength difference threshold value, judge the current physical circuit fault that taken place of antenna-feedback system.
After the embodiment of the invention is obtained the reception total power signal of main diversity antenna and arbitrary diversity antenna of the same antenna; Calculate the strength difference value between diversity antenna; When result of calculation is higher than preset strength difference threshold value; Judge that physical circuit faults such as interface is loosening, feeder line is aging have taken place antenna-feedback system, so that the network key performance indicators worsens.
The method that the physical circuit fault has taken place the detection antenna-feedback system that the embodiment of the invention provides need not to employ special terminal and bigger human resources, and is simple, and accuracy rate is high.Can judge in time that through the method for present embodiment this type of physical circuit fault has taken place antenna-feedback system, then can make fast reaction and safeguard, thereby guarantee that the efficient of base station normally moves, and guarantees the conveying quality of network signal.
Embodiment three, specify referring to Fig. 3, Fig. 3 is the method flow sketch map of the embodiment of the invention three.
Step 201: obtain the main diversity antenna of the same antenna and the reception total power signal of arbitrary diversity antenna.
But about receiving the description refer step 101 of total power signal.
Step 202: obtain the misrouting probability value that main diversity antenna receives total power signal and arbitrary diversity antenna reception total power signal.
Covariance is calculated in the reception total power signal matrix B of the reception total power signal matrix A of main diversity antenna and arbitrary the diversity antenna back of averaging respectively; Again divided by behind A and B variance long-pending; The absolute value of getting the merchant subtracts one, the misrouting probability value that takes absolute value once more and can obtain two diversity reception total power signals.
Specifically can calculate the main diversity antenna of the same antenna and the misrouting probability of arbitrary diversity antenna reception total power signal: P=ABS (ABS (Cov (avg (A), avg (B))/σ through following formula
Avg (A)* σ
Avg (B))-1) * 100%; Wherein, A and B are the main diversity antenna of the same antenna and the reception total power signal matrix of arbitrary diversity antenna, and covariance is calculated in the back of averaging respectively of the numerical value in matrix A and the matrix B, divided by after the amassing of matrix A digital average value and matrix B digital average value variance; The absolute value of getting the merchant subtracts one, takes absolute value once more to be scaled the probability of happening that percentage then obtains branch collection misconnection.
For example, obtained 1254 sample datas that receive total power signal in certain base station, the correlation that obtains through the covariance computing is 0.904, and the probability of the branch collection misconnection that the substitution formula draws is 10%, explains that this base station has taken place to divide the probability of collection misconnection very little.
When using this formula, can the bad point in the sample data not got rid of, make formula easy to use.Bad point is meant owing to some unknown cause, an emergent unusual value, and numerical value recovers normal again afterwards.
Need to prove, also can obtain branch collection misrouting probability value, for example, can realize preserving the mapping relations of relevance values and misrouting probability value, after obtaining relevance values, obtain the misrouting probability value through searching mapping relations through other modes.
Step 203: misrouting probability value that obtains and misrouting probability threshold value are compared, when being higher than the misrouting probability threshold value, judge that the collection misconnection takes place to divide antenna-feedback system.
The misrouting probability threshold value can be provided with according to actual environment flexibly; Can the misrouting probability threshold value turned down when higher the cell data quality requirement; When the cell data quality requirement is relatively hanged down, the misrouting probability threshold value is heightened, do not influenced the realization of the embodiment of the invention.
After the embodiment of the invention is obtained the reception total power signal of main diversity antenna and arbitrary diversity antenna of the same antenna; Calculate the misrouting probability of main diversity antenna and arbitrary diversity antenna; When result of calculation is higher than preset misrouting probability threshold value, judge that the collection misconnection has taken place to divide antenna-feedback system; Branch collection misconnection can be referring to Fig. 4, and Fig. 4 is the branch collection misconnection sketch map of embodiment three, and Fig. 4 (a) is for correctly connecing method, and Fig. 4 (b) connects method for mistake.From Fig. 3, can know, divide to collect the inferior inferior Fen Ji position of dividing collection to receive antenna b that misconnection is antenna a, and time branch of antenna b collect the inferior Fen Ji position of having received antenna a.Because that the main diversity antenna of antenna a and time diversity antenna receive is signal a, be signal b and the main diversity antenna of antenna b and time diversity antenna receive, the degree of correlation of signal a and signal b is little.So; Under minute situation of collection reversal connection; Calculate antenna a main diversity antenna (this main diversity reception be signal a) with the reception total power signal of time diversity antenna (this time branch collection actual reception be signal b) between misrouting probability, know then whether the connection error that branch collects reversal connection takes place.When both misrouting probabilities are higher than threshold value, can judge the collection misconnection has taken place to divide.
In addition; The embodiment of the invention also can directly obtain to receive the relevance values of total power signal through the covariance computing, concrete formula can be: P=Cov (avg (A), avg (B)); Wherein, A and B are the main diversity antenna of the same antenna and the reception total power signal matrix of arbitrary diversity antenna, calculate covariance after the numerical value in matrix A and the matrix B is averaged respectively, obtain the main diversity antenna of the same antenna and the relevance values of arbitrary diversity antenna reception total power signal; Relevance values that obtains and preset correlation threshold value are compared, when the relevance values that obtains is lower than the correlation threshold value, judge that the collection misconnection takes place to divide antenna-feedback system.
The detection antenna-feedback system that the embodiment of the invention provides has taken place to divide the method for collection misconnection to need not to employ special terminal and bigger human resources, and simple, accuracy rate is high.Can judge in time that through the method for present embodiment branch collection misconnection has taken place antenna-feedback system, then can make fast reaction and safeguard, thereby guarantee that the efficient of base station normally moves, and guarantees the conveying quality of network signal.
Equally; When antenna exists a main diversity antenna and a plurality of diversity antennas; Can obtain misrouting probability value or relevance values that main diversity antenna receives total power signal and each time diversity antenna reception total power signal respectively; Respectively with the respective doors limit value relatively, when arbitrary misrouting probability value was higher than misrouting probability threshold value or arbitrary relevance values and is lower than the correlation threshold value, judging that antenna-feedback system is current, the collection misconnection taken place to divide.
Divide the collection misconnection also can be inferior branch collection misconnection for the main collection misconnection of dividing.For example; Misrouting probability value at main branch collection and whole diversity antenna reception total power signals is higher than the misrouting probability threshold value; Or the main relevance values that divides collection and whole time diversity antennas to receive total power signals can be judged as the main collection misconnection of dividing when being lower than the correlation threshold value.Be higher than the misrouting probability threshold value in main collection and the misrouting probability value that part time diversity antenna receives total power signal of dividing, or the main relevance values that divides collection and part time diversity antenna to receive total power signal is when being lower than the correlation threshold value, can be judged as and time divides the collection misconnection.
Also can receive the misrouting probability value or the relevance values of total power signal and each time diversity antenna reception total power signal according to main diversity antenna, accurately judging is that the collection misconnection takes place to divide which time diversity antenna, and it is more careful to detect.
Embodiment four, specify referring to Fig. 5, Fig. 5 is the method flow sketch map of the embodiment of the invention four.
Step 301: obtain the corresponding forward adjacent area collection in each sub-district.
The forward adjacent area be the antenna main lobe direction over against several adjacent areas; The terminal switches to the forward adjacent area from this sub-district, need not change frequency, but conserve system resources; Therefore under normal circumstances, the terminal switch to the number of times of forward adjacent area should be than switching to other any sub-districts often.Referring to Fig. 6, Fig. 6 is embodiment four sub-district distribution schematic diagrams.From Fig. 6, can know, the forward adjacent area collection a of sub-district 1 be the sub-district 2,3,4,10,11,12, and 13}, the forward adjacent area collection c of sub-district 3 then be the sub-district 1,2,4,5,6,7,8}.
And under the situation of sub-district 1 and sub-district 3 misconnection, in fact the forward adjacent area collection of sub-district 1 has become forward adjacent area collection c, and in fact the forward adjacent area collection of sub-district 3 has become forward adjacent area collection a.Referring to Fig. 7, Fig. 7 is embodiment four sub-district misconnection sketch mapes, and Fig. 7 (a) is for correctly connecing method, and Fig. 7 (b) connects method for mistake.The sub-district misconnection is that antenna a main divides collection and time divide collection to receive the main of antenna b to divide collection and time Fen Ji position, and antenna b main divides collection and time divide collection to receive main collection and time Fen Ji position divided of antenna a.Because; The main diversity antenna of antenna a is the signal of sub-district 1 with time diversity antenna reception/transmission; And the main diversity antenna of antenna b and time diversity antenna reception/transmission is the signal of sub-district 3; So the misconnection of antenna a and antenna b also just makes the actual coverage area territory of sub-district 1 and sub-district 3 put upside down.
During the sub-district misconnection, business can normally be initiated in each sub-district, therefore in the manual detection process, is difficult to find this type mistake; Can only aware the KPI Key Performance Indicator step-down of sub-district.
Step 302: the terminal that statistics is in this sub-district switches to the number of times except that concentrated sub-district, each corresponding forward adjacent area of this sub-district sub-district from this sub-district, obtain statistical value.
For example; The terminal is positioned at sub-district 1 at present; Then counting the terminal respectively is X from the number of times that sub-district 1 switches to the sub-district the corresponding forward adjacent area collection a in sub-district 1, and the number of times that switches to the sub-district the corresponding forward adjacent area collection b in sub-district 2 from sub-district 1 is Y, switch to the sub-district the corresponding forward adjacent area collection c in sub-district 3 from sub-district 1 number of times is Z.
In like manner, can count the terminal from the sub-district 2 and sub-district 3 switch to the number of times of each forward adjacent area collection.
Step 303:, judge that then the sub-district misconnection takes place in this sub-district if the terminal switches to the number of times of the sub-district of concentrating corresponding forward adjacent area, this sub-district less than any value the statistical value from this sub-district.
For example, if in X, Y, Z, X is less than any value among Y or the Z, and promptly X is not a maximum, judges that then the sub-district misconnection has taken place in sub-district 1.In like manner, judge sub-district 3 the sub-district misconnection has also taken place.
Embodiment of the invention statistics terminal switches to the number of times of the sub-district of concentrating each forward adjacent area from this sub-district, the number of times that switches to corresponding forward adjacent area, this sub-district at the terminal from this sub-district judges that the sub-district misconnection takes place in this sub-district during greater than its residual value the statistical value.
The method of the detected cells misconnection that the embodiment of the invention provides need not to employ special terminal and bigger human resources, and is simple, and accuracy rate is high.
