Description
[technical field]
The present invention relates to communication technical field, specifically one joins the method for problem and interference problem based on measurement and report data location worker.
[background technology]
The development that reaches its maturity along with the GSM network; It is optimized to have entered into to get into and becomes more meticulous the optimizing phase, more and more embodies its importance so its worker joins problem (longitude and latitude, deflection, angle of declination, stand high), interference problem unusual interference such as (etc.) disturb antenna electric property, repeater, band is outer.For these parameters, present method is:
1. longitude and latitude: can only verify on the spot through the scene and find;
2. deflection: connect anti-sub-district for antenna, can verify through neighboring BS relationship, but for precision problem, can only be through going each the station examine on the spot prospecting of base station problem;
3. mechanical tilt angle: climb up the base station through the engineering staff and verify its correctness;
4. the station is high: verify its correctness on the spot through the engineering staff;
5. antenna electric property: come through disconnected station, analyze the electric property of its antenna with instrument one by one;
6. unusual interference the: find to disturb sub-district bigger than normal through unusual kpi index;
7. Intermodulation Interference performance: come through disconnected station, analyze its Intermodulation Interference performance one by one with instrument;
8. whether disturb the repeater: analyze because the interference that the repeater causes through disconnected repeater.
For the problem of antenna feeder electric property, the problem in the construction, the outer interference of band, can only just can find problem through manual work generaI investigation one by one, its shortcoming comprises following several respects:
1) inefficiency, verifying does not have sense of direction, can only pinpoint the problems through a large amount of generaI investigations;
2) workload is big: each worker's ginseng all wants engineering staff's examine on the spot could find whether have problems;
3) influence existing network: for problems such as antenna electric property, intermodulation performance, the repeater index test analysis problem one by one of standing of need breaking, analyze for large-scale disconnected station, bigger to web influence.
[summary of the invention]
The objective of the invention is to design a kind of interference problem method of efficiently checking and examining that does not influence network to above-mentioned deficiency.
To achieve these goals, the present invention designs a kind of method based on measurement and report data discovery worker's ginseng and interference problem, it is characterized in that this method may further comprise the steps:
A, collection measurement and report data:
Need to open the measurement data reporting functions of base station system,
Owing to give the correct time on the mobile phone, can only report the signal in the neighbor cell, so for most equipment, need the current adjacent area of combing again once, reserve enough rooms for doing virtual adjacent area and effective measurement setup;
Gather the measurement and report data according to measurement setup;
B, set up the interference relationships matrix:
According to the measurement and report data of gathering, obtain the interference relationships between signal distributions situation, main plot and the adjacent area of main plot.Set up the interference relationships matrix;
C, judgement antenna feeder problem:
1) judge the longitude and latitude problem:
If the interference relationships that reports of current area is that to be distributed on the intermediate value be dissatisfied, analysis that interference relationships more strong nearer from sub-district distance, then the longitude and latitude of possible current area is unusual;
2) scene classification:
For the unusual sub-district of non-longitude and latitude, limited needs carry out scene classification.For different scene, the regularity of distribution of signal is not quite identical, and the sub-district that we will be under the similar communication environments is classified as one type;
3) antenna is done abstract modeling:
According to the theoretical coverage distance of antenna type that the sub-district disposed, main plot, obtain the antenna gain on each point of each sub-district, according to the antenna gain on each point, take out the antenna gain distribution situation of each sub-district;
4) pathlosss that calculates each sub-district distributes:
According to the main plot signal distributions and the antenna gain distribution situation of measurement and report, calculate the distribution situation of the pathloss of each sub-district;
5) screen unusual pathloss sub-district in each scene:
For every kind of scene, filter out the unusual sub-district of pathloss, bigger than normal or less than normal;
6) reason being done in unusual pathloss sub-district judges:
For pathloss sub-district bigger than normal, maybe be bigger than normal, high on the low side, the antenna problem of aging or do not have problems such as filling zero point of standing for angle of declination;
For pathloss sub-district less than normal, maybe be less than normal for angle of declination, stand high higher, go up lobe and suppress problems such as difference;
7) judge the strongest sub-district direction of interference signal according to reported data, with the sub-district actual towards doing contrast, judge whether whether deviation or antenna connect instead at the azimuth;
D, locate unusual interfered cell:
1),, assesses out the matter difference ratio of each sub-district through the emulation evaluator according to interference matrix;
2), obtain the matter difference ratio of each sub-district through the measurement and report data;
3) contrast simulation device assessment and matter difference ratio measurement and report find simulator to choose only poor sub-district on the low side;
4) this sub-district is the sub-district of receiving unusual interference;
E, segmentation interference problem and location interference source:
1) judge whether Intermodulation Interference:
According to the Intermodulation Interference formula, calculate the frequency after each sub-district intermodulation:
Third order intermodulation: F (IM3)=2*F1-F2 or F (IM3)=2*F1+F2
Five rank intermodulation: F (IM5)=3*F1-2*F2 or F (IM3)=3*F1+2*F2,
The frequency that produces after unusual subdistrict frequency point that disturbs of contrast and the intermodulation is if with the frequency situation, then orient because the intermodulation performance interference source sub-district that causes not up to standard;
2) judge whether the interference that the repeater causes:
For the unusual interfered cell in non-Intermodulation Interference sub-district, judge whether to be with the repeater, possibly be the interference that the repeater causes in this way;
3) judge whether the interference that high configuration causes:
Sub-district for non-Intermodulation Interference, the interference of non-repeater judges whether high configuration, possibly highly dispose the interference that causes in this way;
F, the outer judgement that reaches other interference of band:
If in above-mentioned condition, do not navigate to the interference source of intermodulation, then maybe be for being with outer or other interference.
The present invention compared with prior art, its advantage is:
Reduce the census operations amount: for the worker join problem (comprise but be not limited to longitude and latitude, azimuth, angle of declination, stand high) need not each station and all go generaI investigation, a problem generaI investigation that only needs to verify out according to software gets final product;
Minimizing is for the influence of network: for antenna electric property problem, Intermodulation Interference index problem, repeater interference problem etc., software can provide the problem cells tabulation, reduces unnecessary verification, and minimizing is for the influence of network;
Through software evaluation emulation, accurately the location interference source problem reduces the manual analysis workload.
