Using the technology provided, the weak covering matter of location repeater analyzed using the special MR of differentiation is poor, passes through difference
Alienation MR statistical analyses, the weak covering repeater hung under intelligent discrimination cell and non-weak covering repeater, it is straight to be accurately positioned
Matter is poor caused by putting the weak covering in station.It is weak covering matter difference repeater, this table that correlation coefficient r, which meets the repeater corresponding to threshold value,
Bright, which is since matter caused by weak covering is poor, rather than it is poor that matter is resulted in due to other.
Relationship between cell and repeater is, BTS management several cells, in each cell, in order to make
The range for obtaining the MPS process is big as far as possible, and the signal provided is clear enough, mounts several repeaters in the cell.
During user carries out wireless communication, mobile terminal (mobile phone) can carry out data according to intervals automatically
It includes many information, such as matter difference information, signal strength information, TA information etc. to sample and report MR, each sampled point to base station.
User is once conversed, and a number of MR sampled points are will produce, and the duration of call is longer, and data sampling point is more, Zhi Houke
To be distributed according to the TA of base station (being also applied for cell) total sampled point, the traffic distribution feelings of this base station (cell) are confirmed
Condition.
Such as about in the relationship of sampled point TA and repeater position：If normal condition, cell is not lower to hang repeater,
The traffic majority of so cell concentrates on nearby 1000 meters or so of cell, then the TA majorities of sampled point are TA=0 and TA=1,
One TA=550 meters；But when hanging repeater under cell, situation can become different, if apart from cell 3000 meters have
A repeater, this repeater is also that can absorb traffic, at this point, the TA distributions of cell can be in TA=0, TA=1, TA=5, TA
All there is sampled point in=6 position.
Therefore, the use matter difference sampled point in embodiment and using weak covering sampled point refer to, using qualified spy
Different MR.Specifically, it in matter difference analytical procedure, is sampled using uplink matter difference, the specific spy acquired under the conditions of uplink Rxqual5~7
Different MR.In a preferred embodiment, the matter difference repeater for point location (matter is poor) cell being sampled using matter difference includes：
By Conjoint Analysis general measure report pledge difference repeater and non-matter difference repeater are distinguished with special measurement report；
It identifies domain time ahead account TA maximum values, repeater is estimated at a distance from information source cell by TA maximum values, with
This location repeater；
It is inquired under the proximal end digital fiber remote radio (GRRU, GSM Digital Remote RF Units) different remote
The time delay of end-repeater is arranged, and size is arranged by time delay is matched with the domain time ahead account TA values at wave crest, is positioned
The specific geographical location in matter difference repeater.A usual proximal end is with several distal ends, and proximal end can be regarded as control network element, and distal end is then
It is radiation network element.
Due to may be inaccurate about putting on record for repeater, needs to test according to actual conditions, be determined by testing
The repeater position of position out is newest most accurate.
In an application scenarios, in the matter difference analytical procedure of repeater, it is accurately positioned the matter difference repeater of matter difference cell
Including：
The first step using the method for Conjoint Analysis routine MR and special MR, is distinguished and is isolated as shown in Figure 2 A and 2 B
Matter difference network element and non-matter difference network element.
As shown in Figure 2 A, the TA distributions that conventional MR is measured find that, there are four wave crest, each wave crest indicates that a traffic is close
Collect point, primary peak is information source cell, second and third and four wave crests are the repeater hung under information source cell.
In the embodiment of the present invention, weak covering repeater is positioned based on differentiation MR analyses.As shown in Figure 2 B, it is special MR
Obtained TA distributions are measured, acquisition is the MR from matter difference network element under the conditions of Rxqual5~7, and comparison diagram 2A and Fig. 2 B can
To find, Fig. 2 B medium wave peaks one and wave crest two disappear, this explanation：Wave crest one, that two sampled point of wave crest belongs to non-matter difference information source is small
Area and non-matter difference repeater, Rxqual is mainly 0-4；Wave crest three and the matter difference network element that wave crest four fundamental rules are mainly Rxqual5-7, this
In refer to repeater, it is achieved that matter difference network element and the discrimination of non-matter difference network element with detach.
Second step is directly put by identifying domain time ahead account TA maximum value location repeaters by the estimation of TA maximum values
It stands at a distance from information source cell with this location repeater.Mainly realize the positioning of the poor repeater of confrontation.
Maximum time lead TA refers to that mobile station signal reaches the real time of base station and assumes the mobile station and base station
Mobile station signal reaches the difference of the time of base station when distance is 0.Here for convenience of understanding and calculate, to the physical significance of TA into
Simplification is gone, therefore, TA can be regarded as the wireless transmission time delay between distal end repeater and information source cell, domain time ahead account
The measurement of TA is there are quantization error, and TA=0 corresponds to mobile terminal user and is distributed as 0~550 meter, and TA=1 corresponds to user distribution and is
550~1100 meters ..., thus with TA values calculate apart from when, need correct TA, usually take correction amount delta ta=0.5, then estimate matter
The distance between poor repeater and information source cell are * 550 meters of d=(TA+ Δ ta).
In this way, then having obtained the distance between each matter difference repeater and information source cell, this distance is in subsequent third
It can be applied to specifically position the geographical location of matter difference repeater in step.
Third walks, and the time delay setting of different distal ends-repeater R1/R2/R3 is inquired under the proximal ends GRRU, is arranged by time delay
Size is matched with TA values at second step medium wave peak, the geographical location of positioning matter difference repeater.If the processing delay of repeater
It is T, every km the propagation delay time T0, TA of optical fiber are the wireless transmission time delays between distal end repeater and mobile terminal.Such as Fig. 4 institutes
Show, the optical fiber transmission delay Tg of distal end R1/R2/R3 is：
Tg (R1)=L1*T0+T；
Tg (R2)=(L1+L2) * T0+2*T；
Tg (R3)=(L1+L2+L3) * T0+3*T；
Therefore：
Tg(R1)<Tg(R2)<Tg(R3)；
Tg from big to small, is just mutually matched with the TA of conventional MR distributions.According to the TA of matter difference traffic distributions (in second step
Obtain) and information source cell under each distal end repeater matched to the optical fiber transmission delay size of proximal end, then can orient letter
Which repeater hung under cell-of-origin occurs that matter is poor, then this repeater is matter difference repeater.Theoretically, it distally arrives close
Terminal delay time is maximum, that is, represents distance farthest, correspondingly, TA numerical value should be the largest, this principle is applied to matching process
In, then it can obtain the particular geographic location of matter difference repeater.
In weak covering analyzing step, sampled using the weak covering of uplink, the specific acquisition weak covering signal strength of uplink is less than etc.
In the sampled point of signal strength threshold；Signal strength threshold can be specifically 100, i.e. the weak covering signal strength RxlevUL< of uplink;
=-100.
It further include description step before positioning step：Matter difference is described respectively according to matter difference sampled point and weak covering sampled point
It can curve and weak covering performance curve；
Therefore, positioning step specifically includes：On description matter difference performance curve and weak covering performance curve, to weak covering
RxlevUL<The TA of=- 100 sampled point and the sampled point of matter difference RxqualUL5~7 is fitted analysis and obtains related coefficient
R positions weak covering matter difference repeater.
The process for analyzing the weak covering in repeater and analysis repeater matter difference is almost the same, difference lies in：
Analysis repeater matter difference is the uplink matter difference sampling during the special MR of analysis is measured；It is then point to analyze the weak covering in repeater
Analyse the uplink weak signal RxlevUL< during special MR is measured;=-100 weak covering sampled point is directly put with this to position weak covering
It stands.
In a preferred embodiment, analysis uplink weak signal RxlevUL<=-100 weak covering sampled point, positioning are weak

RAMDC:RID=MRRID00, CELL=ALL；
RAMDC:RID=MRRID00, MEASTYPE=RXLEVUL, MEASINT=LTOE, MEA SLIM=9；

Therefore, by analyzing uplink weak signal RxlevUL, weak covering repeater is positioned, directly with the weak covering of this discrimination analysis
Put station and non-weak covering repeater.
