Description
Technical field
The present invention relates to fields of communication technology, more particularly to a kind of neighbor cell optimizing method and dress based on network communication
It sets.
Background technology
Neighborhood Optimization is one of the main work for promoting mobile cellular network travelling performance, and user can be ensured in movement
In the process, it occupies always and arrives most suitable cell, obtain most reasonably covering and best network service.In gsm networks, adjacent
Area's optimization is the important means for reducing network call drop, improving network interferences, promoting speech quality.
In existing neighbor cell optimizing method, optimize expert with the adjacent cell list of the immediate Ericsson of this programme
（Neighboring Cell List Optimization Expert, hereinafter referred to as NOX）.The program is by collecting mobile phone pair
The measurement data of peripheral cell（Measurement Report, hereinafter referred to as MRR）, and the switching times of minizone are combined, come
It assesses whether to need to increase or delete adjacent area.
As shown in Figure 1, adjacent area deletion flow is in NOX methods：When switching number of attempt less than a threshold value Rmv,
The adjacent area is added " deleting neighboring cell list ".When total BCCH measurement frequency point lists（BCCH Allocation List, it is simple below
Claim BA tables）When length is long, the cell neighboring relation in the list is deleted successively.
As shown in Fig. 2, increasing the flow of adjacent area in NOX methods is：Measurement cell relative signal intensity in MRR reports
It when more than a certain thresholding, is added into " increasing adjacent area candidate list ".When the BA tables length of Target cell and this cell is all permitting
When within the scope of perhaps, then increase this to adjacent area；When Target cell or this cell BA tables are more than maximum allowable length, then do not increase
Add this to adjacent area.
The NOX neighbor cell optimizing methods of Ericsson, although having considered, the switching of minizone, mobile phone reports in cell
The factors such as MRR measurement data, but there is also following deficiencies：
When deleting adjacent area, the factor that NOX methods consider is excessively unilateral, and only the switching number of attempt according to statistics, right
In the low adjacent area of switching number of attempt, will be deleted.And in actual conditions, if there is such user behavior event occurs,
Although probability is relatively low, but as long as the switching occurred to Target cell is attempted, it is most likely that lead to call drop because no adjacent area is changeable.
So there is the risk for accidentally deleting adjacent area in NOX.
When increasing adjacent area, NOX methods consider merely the relative signal intensity of MRR.For present GSM network, due to
Covering is quite perfect, and mobile phone tends to receive the cell of a large amount of strong signals.Especially city, signal are higher than the frequency of -70dBm
Point can at least receive twenty or thirty.In this way to the cell in core city, just necessarily there is the adjacent area of a large amount of candidates that can increase.NOX is mono-
It is pure to determine increased neighboring BS relationship from signal relative intensity, it necessarily will appear the phenomenon that " jump " defines adjacent area, that is, define
Cell farther out is as adjacent area, although and the closest geographically cell of oneself may be not so good as a distant place by force due to signal instead
Certain cell is strong and could not be defined as adjacent area, causes " area covered ", increases the cover jamming to other cells.
When considering BA table length, due to each cell independence searching neighboring area candidate cell in NOX methods, can exist opposite
The good cell of signal, due to evening assessment, BA tables are long and can't be adjacent area, and the cell of suboptimum is due to early assessment, BA tables
Temporarily there is position and is defined as adjacent area.Such as：, to cell A and B, the relative signal of A → B is very strong for certain, the opposite letter of B → A
It is number very weak.But since B first assesses A, then since A → B is very strong, and the BA tables of A/B all do not reach maximum length also, then by A/B
It is defined as two-way adjacent area；But since B → A is very weak, A also had more preferably that C is as adjacent area originally, but since BA tables at this time have been more than most
Long length, and the adjacent area that C is A cannot be defined as.

Specific implementation mode
To keep the technical problem to be solved in the present invention, technical solution and advantage clearer, below in conjunction with attached drawing and tool
Body embodiment is described in detail.
As shown in figure 3, the flow chart of the neighbor cell optimizing method for an embodiment of the present invention, the neighbor cell optimizing method packet
It includes：
Step S101:Obtain the candidate adjacent of Target cell and existing adjacent area；
Step S102:By the candidate adjacent and existing adjacent area according at a distance from Target cell, antenna relative bearing
And measurement report data MRR determines priority；
Step S103:According to the current adjacent area collection of determining priority output Target cell.
Candidate adjacent and existing adjacent area are added and are deleted according to the mode with Target cell priority level by the present invention
Adjacent area, and with measurement report, geographical location, antenna directional angle, switching statistics various dimensions assess cell association, adjust the distance compared with
Closely, the cell preference of direction air exercise adds adjacent area, rationally controls adjacent area addition.
In step S101, the existing adjacent area of Target cell refers to the adjacent area in Target cell BA tables, is preset work
For the adjacent area of Target cell.The candidate adjacent of Target cell refers to the adjacent area that Target cell can search, which is
It may increase in the BA tables of Target cell.The step is the adjacent area and candidate adjacent obtained in BA tables, not to acquisition
Adjacent area carries out additions and deletions processing.
In step S102, multiple adjacent areas of acquisition are determined into the priority between Target cell, specifically according to
Distance, antenna relative bearing and the measurement report data MRR of Target cell determines priority, including：
Step S1021：Using Target cell as cell-of-origin, the candidate adjacent and existing adjacent area foundation and Target cell
Distance, antenna relative bearing and measurement report data MRR determine the first priority；
Step S1022：Using candidate adjacent and existing adjacent area as cell-of-origin, the Target cell and cell-of-origin
Distance, antenna relative bearing and measurement report data MRR determine the second priority.
Present invention determine that when the priority of the adjacent area and Target cell that obtain, using Target cell as when cell-of-origin, obtain
Adjacent area at a distance from Target cell, antenna relative bearing and measurement report data MRR determine the first priority, simultaneously
Also using the adjacent area of each acquisition as cell-of-origin, Target cell at a distance from cell-of-origin, antenna relative bearing and measure report
Data MRR is accused to determine the second priority, considers two priority.Due between cell pair, it is understood that there may be Target cell
Signal to adjacent area is very strong, but adjacent area is to the not strong situation of the signal of Target cell.For example, certain is to cell A and B, A → B's
Relative signal is very strong, but there may be the relative signal of B → A is very weak, needs to consider simultaneously thus mutual between cell pair
Signal strength.
Step S103, the current adjacent area collection of Target cell be according to the priority between Target cell and the adjacent area of acquisition come
It determines, since the present invention has considered the priority of searching neighboring area and existing adjacent area and Target cell, according to priority come really
The current neighbor for the cell that sets the goal can carry out an Integrated comparative to each adjacent area of acquisition, avoid directly determining adjacent area it
Afterwards, the problem of occurring the stronger adjacent area of new signal again to maximum length in BA expression and addition can not be continued.It is excellent when foundation
When first grade has the first priority and the second priority, current neighbor collection of the invention is to carry out synthesis according to two priority to examine
Consider, to determine the current neighbor collection of Target cell.
The distance between the cell of the present invention is determined according to the distance between place base station, utilizes cell longitude and latitude
Calculate cell station spacing.Due to taking a round within one week totally 40075.04 kilometers around the earth on terrestrial equator, and a circle is divided into 360
Degree, per once under the line on length=40075.04km/360=111.31955km.At the beginning of longitude and latitude are respectively the earth and sheet
Meridian, equator angle.Spherical formula can be utilized to calculate the distance of point-to-point transmission on spherical surface.It is assumed that the warp of two cell A/B
Latitude is respectively（λ A, Φ A and λ B, Φ B）, as shown in figure 4, then the distance calculation formula of cell A/B is d=
111.31955cos { 1/ [ten cos Φ Acos Φ Bcos (λ B-λ A) of sin Φ Asin Φ B] }.
Deflection is to determine being beaten between cell or air exercise between the cell of the present invention, for equidistant small
Area, antenna directional angle air exercise are still beaten, and are influenced on covering very big.Due to bad to shielding properties after some antennas, after causing
It is stronger to lobe power, it influences backwards to cell signal.
The present invention is when calculating deflection air exercise relationship, using rotational coordinates method, latitude and longitude of base station is considered as plane and is sat
Mark system coordinate（The approximation earth is a plane when station spacing is shorter）, coordinate system is rotated into it is with A (X1, Y1) B (X2, Y2) line
The X-axis of new coordinate, while it being rotated by 90 ° the Y-axis as new coordinate counterclockwise, as shown in Figure 5.In new coordinate system, A/B two
Cell is in same level, convenient for analysis air exercise relationship.In new coordinate system, if in two cells of A/B, at least one is small
Area azimuth is within the scope of ± 60 ° towards another cell, and other side's cell deflection is towards this cell ± 90 ° range
Interior, it is air exercise cell to be considered as two cells, otherwise beats cell for the back of the body, as shown in Figure 6.
Multiple adjacent areas of acquisition are determined that the priority between Target cell, priority can be as needed by the present invention
It divides, the present embodiment is that priority of adjacent domain will be divided to 6 grades：
0 grade：Cell and adjacent area neighbouring relations are " defined ", and nearby region measurement no data（BCCH＆BSIC pairs can not be found
The cell answered, or and measurement report MRR quantity<200, or measure absolute level<-90dBm）Or station spacing is 0.
1 grade：Station spacing<1KM, and measurement report MRR quantity>=200, measure absolute level>=-90dBm.
2 grades：Station spacing>=1KM, and<5KM, azimuth air exercise, measurement report MRR quantity>=200, measure absolute level>
=-90dBm。
3 grades：Station spacing>=5KM, and<10KM, azimuth air exercise, measurement report MRR quantity>=200, measure absolute level>
=-90dBm。
4 grades：Station spacing>=1KM, and<5KM, the azimuth back of the body are beaten, measurement report MRR quantity>=200, measure absolute level>
=-90dBm。
5 grades：Station spacing>=10KM or station spacing>=5KM and azimuth, which are carried on the back, to be beaten, measurement report MRR quantity>=200, it surveys
Measure absolute level>=-90dBm.
It is " undefined " for cell and adjacent area neighbouring relations, and adjacent area is sky（It is corresponding small that BCCH＆BSIC can not be found
Area, or and measurement report MRR quantity<200, or measure absolute level<-90dBm）, remove this cell portion.
When adjacent cell has equal priority, the weighted value of the average level according to adjacent cell is preferential further to divide
Grade.According to measurement report data, each average level weighted value " NAVSS weighted values " for measuring cell is calculated.Average level weights
Value reports level NAVSSi and occurrence number TIMESi according to being averaged for the cell in each report, and in the in report
Relationship strong i calculates：NAVSS weighted values=(NAVSS1*TIMES1*6+NAVSS2*TIMES2*5+NAVSS3*TIMES3*4+
NAVSS4*TIMES4*3+NAVSS5*TIMES5*2+NAVSS6*TIMES6)/(TIMES1*6+TIMES2*5+TIMES3*4+
TIMES4*3+TIMES5*2+TIMES6)。
According to priority of adjacent domain division result, since priority 0, each rank according to measuring signal electrical level weighting value
Size sorts successively.BA expression is come to the cell pair before maximum value, the neighboring cell list as exported.For not exporting
The defined adjacent area of neighboring cell list, as deletes adjacent area；For the undefined adjacent area in output listing, as newly-increased adjacent area.
It is also arranged after the cell that the present invention obtains, to remove the smaller cell of correlation, to reduce operand.
This part include arrange measurement report data, delete using the few adjacent area of point to, increase the neighboring cell list that must be added, remove and prohibit
Very few neighboring cell list is attempted in the neighboring cell list that only adds, switching.The time span that measurement report and switching statistical data take can
It is self-defined, it is proposed that take the whole network 7*24 hour datas.
As shown in fig. 7, for the arrangement basic data flow chart of an embodiment of the present invention, remove ban first is defined as neighbour
The cell in area, such as part indoor cell, un-activation cell；Secondly the few cell of switching number of attempt, switching trial time are removed
Number thresholding minHO can be self-defined, it is proposed that is set as 10 times；The few cell of measurement report quantity, measurement report sample door are removed again
Limit minTimes can customize, it is proposed that be 10000 times；Then start decode measurement report data, matching geographically it is nearest with
The identical cell names of measurement report BCCH/BSIC.If nearest cell distance is more than distance threshold maxDistance, then it is assumed that
It is illegal cell, can be also removed.
It includes belonging to same frequency range with Target cell that the present invention, which exports the adjacent area that the current adjacent cell of Target cell is concentrated,
Both cell or the cell for being not belonging to same frequency range, can also have.Such as can be the cell of same frequency range with selected section,

" rule table " is by the priority of adjacent domain of cell-of-origin and Target cell, NAVSS weighted values, forward direction NAVSS rankings, anti-
To NAVSS rankings and whether it is added to homogeneous-frequency adjacent-domain.Table is with cell-of-origin ascending order, priority of adjacent domain ascending order, NAVSS weighted values
The mode of descending arranges.Wherein priority of adjacent domain, NAVSS weighted values are the output knot that first part is " arranging basic data "
Fruit；" ranking of positive NAVSS " and " reversed NAVSS rankings " is initialized as 1；" being added to homogeneous-frequency adjacent-domain " is initialized as N.
After building and initializing completion " rule table ", iteration is started the cycle over.As shown in figure 8, each loop iteration
All it is the update to " rule table ", and counts iterations.After one cycle iteration, " rule table " does not update,
It represents all neighboring BS relationship and all meets pre-defined rule, then iteration terminates." being added to homogeneous-frequency adjacent-domain " in " rule table " is Y
Cell be homogeneous-frequency adjacent-domain relation list.
For the rule table amendment during each loop iteration, using the amendment flow of such as Fig. 8.Specific modification rule
For：
" ranking of positive NAVSS " of first pair of adjacent area of each cell is 1, and " reversed NAVSS rankings " is by reversed neighbour
Cell relation corresponding " ranking of positive NAVSS " obtains.For example the positive ranking of adjacent area B → A is 8, then the reversed ranking of A → B
It is 8.Rule is arranged in " ranking of positive NAVSS " of 2nd adjacent area pair later to adjacent area：
If " being added to homogeneous-frequency adjacent-domain " of lastrow record is Y, " ranking of positive NAVSS " of one's own profession record is upper one
" ranking of positive NAVSS "+1 of row record；
If " being added to homogeneous-frequency adjacent-domain " of lastrow record is N, " ranking of positive NAVSS " of one's own profession record is upper one
" ranking of positive NAVSS " of row record.
" reversed NAVSS rankings " is obtained from reversed adjacent area pair " ranking of positive NAVSS " lookup successively.
" being added to homogeneous-frequency adjacent-domain " is that Y must simultaneously meet following condition：
The affiliated frequency range of cell-of-origin and adjacent cell is identical；
" ranking of positive NAVSS "<=10；
" ranking of reversed NAVSS "<=10.
2. rule and the rule of addition homogeneous-frequency adjacent-domain of adding alien frequencies adjacent area are almost the same, different places have：
Only add 5 in alien frequencies adjacent area；
" being added to homogeneous-frequency adjacent-domain " is that Y must simultaneously meet following condition in " rule table "：(A) cell-of-origin and neighbour
The affiliated frequency range of cell is different；(B) " ranking of positive NAVSS "<=5；(C) " ranking of reversed NAVSS "<=5.
3. the remaining adjacent area of addition
After having added 10 homogeneous-frequency adjacent-domains, 5 alien frequencies adjacent areas, if BA table length is also vacant, by remaining planned number
It is added in the way of adjacent area with frequency, alien frequencies by above-mentioned addition.Unlike, here regardless of whether same frequency alien frequencies, fully according to
Priority of adjacent domain, NAVSS weighted values come ranking, forward preferential increase, until BA expression to length limit.
