The method that connects anti-sub-district for the detection antenna feeder equipment that the embodiment of the invention is provided is elaborated, and sees also following embodiment:
In order to realize that automatically antenna feeder equipment connects anti-detection, reduces the drive test cost, increases work efficiency, the embodiment of the invention provides a kind of method that antenna feeder equipment connects anti-sub-district that detects, and is that example describes with the WCDMA system.
Referring to Fig. 3, for antenna feeder equipment connects normal schematic diagram, wherein, antenna AntennaA and antenna AntennaB correspond respectively to sub-district sectorA and sectorB, and Tx/Rx represents the main collection in sub-district, are used for receiving transmitting; Rx represents cell diversity, is used for received signal.Those skilled in the art can know that antenna feeder equipment connects anti-package and draws together following two types usually: main diversity connects anti-and connects instead with the sub-district, station with frequency.Referring to Fig. 4, for antenna feeder equipment master diversity connects anti-schematic diagram, wherein, misconnection has appearred in the Rx of the Rx of sub-district A and sub-district B, causes having occurred main diversity and connects instead.Referring to Fig. 5, for antenna feeder equipment sub-district connects anti-schematic diagram, wherein, misconnection appears in the Tx/Rx of the Tx/Rx of sub-district A and sub-district B, and misconnection appears in the Rx of the Rx of sub-district A and sub-district B, causes occurring the sub-district and connects instead.
For reverse problem appears in clear and definite antenna feeder equipment is to cause owing to main diversity meets anti-institute on earth, still cause owing to the sub-district meets anti-institute, carry out following step, referring to Fig. 6, the detection antenna feeder equipment that provides for the embodiment of the invention connects the schematic flow sheet of the method for anti-sub-district, and is as follows:
101: in the time period to be measured, obtain the main collection RTWP value and the diversity RTWP value of each antenna in cell of base station.
Wherein, can collect all antenna in cell masters, diversity RTWP value under this base station in the time period to be measured by the form of tracking base stations daily record; Wherein, the value of above-mentioned time period to be measured can be tested needs according to reality and be set, and is generally the time period greater than 2 hours, for example, can value be 2-3 hours, and present embodiment is not done any restriction to the concrete value of this time period to be measured.
For the method that the embodiment of the invention is provided is elaborated, present embodiment is respectively to comprise three co-frequency cells under the base station: sub-district 1, sub-district 2, sub-district 3 are that example describes, correspondingly, collect sub-district 1, sub-district 2, the master of sub-district 3, diversity RTWP value in these 2-3 hours respectively.
102: calculate the main collection RTWP value of each sub-district and the coefficient correlation of diversity RTWP value.See for details as follows:
At first, set the sampling interval, for example, to be a sampled point 1 second; Secondly, calculate the main collection of each sub-district and the coefficient correlation of two groups of data of diversity.For example, suppose that the sampled data points set of the main collection RTWP of sub-district 1 is array A, the sampled data points set of the diversity RTWP of sub-district 1 is array B, and is specifically can algorithm as follows:
P＝Cov(A，B)/σ
A*σ
B
Wherein,
Wherein, x, y be respectively array A and array B average i ∈ (1,2 ..., N)
Therefore, the computing formula that obtains coefficient correlation P is:
So calculate the main collection RTWP value of sub-district 1 and the coefficient correlation of diversity RTWP value by above-mentioned formula, in like manner, can calculate the main collection RTWP value of each sub-district, base station and the coefficient correlation of diversity RTWP value, method is similar, repeats no more.
103: the main coefficient correlation that collects RTWP value and diversity RTWP value according to aforementioned calculation obtains if coefficient correlation levels off to 0, illustrates that then this sub-district antenna feeder equipment connects instead.
104: if the coefficient correlation of the main collection RTWP value of certain sub-district and diversity RTWP value less than default relative threshold, then execution in step 105.
Wherein, this default relative threshold is set according to the test needs by the tester and is obtained.Method for the embodiment of the invention is provided is elaborated, and present embodiment is 0.5 to be example with default relative threshold, and the main coefficient correlation that collects RTWP value and diversity RTWP value of suppose sub-district 1 is 0.3 to describe for example.
105: the same frequency that obtains current area stand the altogether main collection RTWP value of sub-district and the coefficient correlation of diversity RTWP value.
Wherein, this current sub-district is the sub-district of the coefficient correlation of above-mentioned steps 104 described main collection RTWP values and diversity RTWP value less than default relative threshold, suppose that this current sub-district is sub-district 1, then by the Base Station Identification ID in the base station configuration file, descending frequency point information etc., get access to and the same frequency of this sub-district 1 sub-district of standing altogether, and then get access to and the same frequency of this sub-district 1 stand the altogether main collection RTWP value of sub-district and the coefficient correlation of diversity RTWP value, suppose and the same frequency of this sub-district 1 sub-district of standing altogether is sub-district 2, sub-district 3.
106: according to the same frequency of current area stand altogether the main collection RTWP value of sub-district and diversity RTWP value coefficient correlation, preset relative threshold, determine with current area and exist antenna feeder equipment master diversity to connect anti-sub-district.See for details as follows:
1) if with current area with the main collection RTWP value of the sub-district of frequently standing altogether and the coefficient correlation of diversity RTWP value, all be not less than default relative threshold, illustrate that then it is because other reasons causes that current area antenna feeder equipment connects counter, reason such as antenna feeder equipment fault for example, (performance, parameter as antenna can not satisfy instructions for use; Joint sealing is tight, makes steam enter feeder line, influences the signal emission; Decorating position is unreasonable, as being too near to interference source etc.; Transmitter power surpasses antenna power rating, makes the antenna overload or burns; Suffer foreign object, typhoon, thunder and lightning etc., changed antenna original structure and performance parameter, degenerate, forbidden; The cable end not prison welding is solid, and signal cuts in and out or the like); This situation is not within the scope that present embodiment is considered.
2) if with current area with in the sub-district of frequently standing altogether, have and have only the main collection RTWP value of a sub-district and the coefficient correlation of diversity RTWP value to be lower than default relative threshold, illustrate that then this sub-district and above-mentioned current area antenna feeder equipment occurred and connect instead.
For example, the same frequency of supposing sub-district 1 is stood in the sub-district altogether, only exist the main collection RTWP value of sub-district 3 and the coefficient correlation of diversity RTWP value to be lower than default relative threshold, and the main collection RTWP value of sub-district 2 and the coefficient correlation of diversity RTWP value are not less than default relative threshold, illustrate that then sub-district 3 main diversity occurs with sub-district 1 and connects instead.
3) if with current area with in the sub-district of frequently standing altogether, exist the main collection RTWP value of at least two sub-districts and the coefficient correlation of diversity RTWP value all to be lower than default relative threshold, then calculate the coefficient correlation of the diversity RTWP value of the main collection RTWP value of current area and the sub-district of frequently standing altogether together respectively, if the coefficient correlation that calculates levels off to 1, illustrate then that this coefficient correlation levels off to and 1 pairingly main diversity occurs with frequently stand altogether sub-district and above-mentioned current area and connect instead.
For example, the same frequency of supposing sub-district 1 is stood in the sub-district altogether, there is sub-district 2, the main collection RTWP value of sub-district 3 and the coefficient correlation of diversity RTWP value all are lower than default relative threshold, then further, the coefficient correlation of the main collection RTWP value of calculation plot 1 and the diversity RTWP value of sub-district 2, and the coefficient correlation of the diversity RTWP value of the main collection RTWP value of sub-district 1 and sub-district 3, suppose, the coefficient correlation of the main collection RTWP value of calculation plot 1 and the diversity RTWP value of sub-district 2 levels off to 1, the coefficient correlation that is the main collection RTWP value of sub-district 1 and sub-district 2 is the coefficient correlation maximal term, illustrates that then sub-district 1 main diversity occurs with sub-district 2 and connects instead.
So far, by above-mentioned steps 101-106,, according to the same frequency of current area stand altogether the main collection RTWP value of sub-district and diversity RTWP value coefficient correlation, preset relative threshold, determine with current area and exist antenna feeder equipment master diversity to connect anti-sub-district.
Referring to Fig. 7, by carrying out following steps, to confirm whether current area exists the sub-district reverse problem, sees for details as follows:
201: optimization data and the soft handover information of obtaining the homogeneous-frequency adjacent-domain of current area in the time period to be measured;

Above-mentioned soft handover information specifically comprises: soft handoff event number of times, soft handoff event time, Active Set cell ID ID, Target Cell Identifier ID;
Wherein, those skilled in the art can be known, above-mentioned 1A incident is meant that relative threshold increases incident, in the mobile communications network of WCDMA standard, the quality of a sub-district of expression is near best cell or Active Set quality, when UE (UserEquipment, user terminal) measurement found that the Primary Common Pilot Channel of a detected set sub-district is better than the Primary Common Pilot Channel of a sub-district in the current Active Set, UE reported the 1A event report by measurement report; Above-mentioned Active Set be meant with UE between exist soft handover to be connected the sub-district, UE can be a mobile phone; Above-mentioned detected set is meant the sub-district list that UE continuously measures, but the district pilots Ec/Io value in this sub-district list is enough not big, is not enough to add Active Set; Above-mentioned Target cell is meant a certain sub-district that UE is moved to by the Active Set sub-district, and promptly soft handover takes place for Active Set sub-district and this sub-district, and this sub-district is a Target cell; Above-mentioned Ec/Io refers to chip energy/interference power spectrum density; Ec/No refers to RSCP/RSSI (ReceivedSignal Strength Indication, received signal intensity); So-called soft handover is meant the change of UE place communication cell under the CELL-DCH state, and in the WCDMA system, soft handover carries out between shared channel;
202: according to above-mentioned 1A reporting events number of times with default obtain thresholding, obtain optimum subdistrict;
Wherein, suppose that get access to the 1A reporting events 6 times, ginseng is shown in Table 1 in the testing time section,
