Description

A kind of method moving communication network service equilibrium based on business statistics data

Technical field

The present invention relates to mobile communication business technical field.

Background technology

In mobile communication network planning process of construction, to base station distribution, every cell coverage area and every local resource Configuration quantity design, be all according to early stage business demand estimation carry out, and the important foundation of this estimation be exactly In certain area coverage, the demand of supposition business is uniform.And the mobile communication business demand of reality often has macroscopic aspect More uniform, but the feature that microcosmic point is the most uneven.Such as: averagely every square kilometre 200 Ai Er of urban area traffic density Orchid, practical business is distributed each square kilometre very close to 200 Ireland；If but the service decomposition that a square kilometre interior is arrived On each 100*100 zonule, often focus in a small amount of zonule.This allows for the planning stage and is uniformly distributed according to business The MPS process of design and resource distribution can not fully meet the needs of practical business.Therefore, runed at mobile communications network Cheng Zhong, will be adjusted by resource and business is shared means to carry out the business of whole network equal according to the change of practical business demand Weighing apparatus, this is also the important content of mobile communication network optimization work.

Existing main solution is:

1, according to congestion metric situation in traffic measurement, in conjunction with practical work experience, by " tearing not busy benefit open to hurry ", i.e. reduce low Loaded cell configures, the method increasing congested cell configuration, carries out passive type resource distribution adjustment.Self industry of Main Basis community Business load, the adjacent each cell conditions of less consideration.

2, by software approach such as activation specific function, parameter adjustments, the business sharing condition between adjacent cell is entered Row sum-equal matrix.Less adjustment base station covers, even if adjusting also is to use " according to road test, the result of test calls, with reference to user Calling information, in conjunction with practical work experience, carries out the most coarse passive type by the way of adjusting antenna azimuth and covers excellent Change ".The situation of the adjacent each community of same less consideration.

Existing passive type method has a disadvantage in that

1, " tearing not busy benefit open to hurry " method of passive type, does not increase the Serving cell number in traffic hotspots region, only increases service money Source configures, and portion of base stations carrier configuration can be caused too much, in fact it could happen that configuration is serious uneven, brings the most tired to frequency planning Difficulty, increasing considerably of network interferences, reduce network quality.Serving cell quantity in hot spot region is very few simultaneously also brings along necessarily System risk.

2, the business carried out by the means such as software function, parameter shares strategy, is essentially that to have ignored business congenital The mandatory business of lack of uniformity is shared.Usually make terminal by poor cell serves, objectively cause network quality and decline.

Summary of the invention

The guiding theory of the application method is: using mutually adjacent community as an entirety, unified consider to cover equilibrium and Traffic load equalizes.By selecting different strategies, the resource distribution realized respectively in the whole network the scope of adjacent area needs with business Seek relative equilibrium.Problem present in above-mentioned existing method can be solved.

Technical scheme is as follows:

One moves communication network service equalization methods based on business statistics data, and described method step is as follows:

Step 1: obtain network configuration and business statistics data；

Step 2: calculate each cell configuration equalizing coefficient, Ji Gai community is compared with its adjacent area, and configuration is high or low；

Cell configuration equalizing coefficient

Wherein c_iFor this cell configuration number of channel, n is this adjacent adjacent area, geographical position, community quantity, c_nEach for this community Adjacent adjacent area, geographical position quantity configurating channel number；This coefficient configures higher on the occasion of representing this community compared with its adjacent area, negative value Representing on the low side, order of magnitude represents the number of higher degree on the low side；

Step 3: calculate each cell load equalization coefficient, Ji Gai community is compared with its adjacent area, and load is high or low；

Cell load equalization coefficient

Wherein: tl_iFor this community peak value every line telephone traffic calculated in step 1, tl_nAdjacent for this geographical position, community Adjacent area peak value every line telephone traffic, n is this adjacent adjacent area, geographical position, community quantity；This coefficient is on the occasion of representing this community and its adjacent area Comparing traffic load higher, negative value represents on the low side, and order of magnitude represents the number of higher degree on the low side；

Step 4: calculate the reasonable coefficient of each cell configuration, Ji Gai community is compared with its adjacent area, and configuration resource is the most reasonable； Each cell configuration equalizing coefficient and load balancing coefficient according to calculating in step 2 and step 3 screen, and retain:

Config_Balance_Factor_i×Traffic_Balance_Factor_i< the community of 0；

Calculate and be retained the reasonable coefficient of cell configuration:

$\begin{array}{c}Config\_Feasible\_{\mathrm{Factor}}_i\\ =\frac{Config\_Balance\_{\mathrm{Factor}}_i\&times;\sqrt{Config\_Balance\_{{\mathrm{Factor}}_i}^2+Traffic\_\_Balance\_{{\mathrm{Factor}}_i}^2}}{ABS(Config\_Balance\_{\mathrm{Factor}}_i)}\end{array}$

This coefficient is on the occasion of representing this community " height is joined low negative "；Negative value represents this community " low height of joining is born ", and absolute value represents should The unreasonable degree of cell configuration；

Step 5: screening identification need to adjust configuration community, identifies that the community of relatively high configuration underload is Xu Jianpei community, Relatively low configuration high load capacity community is Xu Zengpei community；Arranging a configuration reasonability thresholding really needs adjustment to join in order to judging The community put:

Presently suggested CONFIG_FEASIBLE_THRESHOLD=0.7

Config_Feasible_Factor_i＞ CONFIG_FEASIBLE_THRESHOLD is identified as Xu Jianpei community； Config_Feasible_Factor_i＜-CONFIG_FEASIBLE_THRESHOLD is identified as Xu Zengpei community；

Each Xu Zengpei community, is also performed to repeater and zooms out station filtration, and Xu Zengpei community has hung repeater simultaneously or drawn Remote station, Ze Gai community is removed from need to increase to join cell list, is labeled as " zooming out a little newly-built " simultaneously, recorded the increasing of band repeater and join Cell list；

Step 6: calculate every community and increase and join to subtract and join scale, can be according to the whole network traffic load is average or adjacent cell is relatively flat Equal two kinds of tactful differences, calculate respectively to increase to join to subtract accordingly and join scale；

A) subtract join scale calculate:

Presetting and subtract and join elastic allowance REDUCE_MARGIN, this margin value is channel reservation number, be used for avoiding subtracting join after anti-words Business impact capacity is deteriorated, and the suggestion of this surplus takes 0-4, and preliminary advice value is 2；

The each Xu Jianpei community identifying previous step, calculates it and can subtract prestowage frequency amount；

900M or 1800M community:

$\mathrm{Re}ducable\_Trx\_{\mathrm{Number}}_i=INT\left(\frac{c_i\&times;\left(MIN\right(\stackrel{\&OverBar;}{tl},0.9)-{\mathrm{tl}}_i)-REDUCE\_MARGIN}{8*\max (\stackrel{\&OverBar;}{tl},Load\_t\arg et\_cell)}\right);$

Wherein c_iFor this cell configuration number of channel, tl_iFor this community peak value every line telephone traffic calculated in step 1,For The meansigma methods of adjacent area adjacent with its geographical position, Xu Jianpei community every line telephone traffic；MIN () is little for taking, and max () is big for taking, INT (), for rounding, Load_target_cell is parameter preset " the load desired value that this Xu Jianpei community is corresponding "；

B) increase join scale calculate:

Arrange optional " configuration equalization target strategy " parameter, option be " pursuit load is uniform ", will Zeng Pei community Every line telephone traffic adjusts to geographical position the meansigma methods of adjacent adjacent area and " reaching load target " will every line words of Zeng Pei community Business amount adjusts to load desired value, as selected " pursuing load uniform ", then:

$Add\_Trx\_{\mathrm{Number}}_i=INT\left(\frac{c_i\&times;({\mathrm{tl}}_i-MIN(\stackrel{\&OverBar;}{tl},0.9))}{8*\stackrel{\&OverBar;}{tl}}\right)+1;$

As selected " reaching load target ", then:

$Add\_Trx\_{\mathrm{Number}}_i=INT\left(\frac{c_i\&times;({\mathrm{tl}}_i-Load\_t\arg et\_Cell)}{8*Load\_t\arg et\_Cell}\right);$

Wherein c_iFor this cell configuration number of channel, tl_iFor this community peak value every line telephone traffic calculated in step 1,For The meansigma methods of adjacent area adjacent with its geographical position, Xu Zengpei community every line telephone traffic, MIN () is little for taking, INT () for rounding, Load_target_cell is parameter preset " the load desired value that this Xu Zengpei community is corresponding "；

Step 7: the more newly configured load that recalculates: according to resource distribution situation new after adjusting, recalculate each little The traffic load in district:

(1) for each Xu Zengpei community, such as the Add_Trx_Number calculated_i＞ 0, then calculate this community newly configured The number of channel:

c_inew=c_i+7*Add_Trx_Number_i

If Zeng Pei community is CBCCH community, then compare this community tl_i900, tl_i1800；

Such as tl_i900＞ tl_i1800, then increase pairing as 900 carrier frequency:

c_i900new=c_i900+7*Add_Trx_Number_i

Such as tl_i900＜ tl_i1800, then increase pairing as 1800 carrier frequency:

c_i1800new=c_i1800+7*Add_Trx_Number_i

Wherein c_iFor this cell configuration number of channel, Add_Trx_Number_iRule are joined in the need increasing calculated for previous step

Mould, tl_i900, tl_i1800It is respectively 900M, 1800M every line telephone traffic；

(2) for each Xu Jianpei community, such as the Reducable_Trx_Number calculated_i＞ 0, then calculate this community The newly configured number of channel:

c_inew=c_i-7*Reducable_Trx_Number_i

If Jian Pei community is CBCCH community, then compare this community tl_i900, tl_i1800；

Such as tl_i900＞ tl_i1800, then pairing is subtracted as 1800 carrier frequency

c_i1800new=c_i1800-7*Reducable_Trx_Number_i

c_i900new=c_i900

Such as tl_i900＜ tl_i1800, then pairing is subtracted as 900 carrier frequency

c_i900new=c_i900-7*Reducable_Trx_Number_i

c_i1800new=c_i1800

Wherein c_iFor this cell configuration number of channel, Reducable_Trx_Number_iThe need calculated for previous step subtract

Join scale；

(3) then calculate each cell configuration change after prospective peak value every line telephone traffic:

900M community:

tl_inew=tl_i*c_i/c_inew

1800M community:

tl_inew

=(tl_i+(Load_target_Cell_1800

-Load_target_Cell_900))*c_i/c_inew

-(Load_target_Cell_1800-Load_target_Cell_900)

CBCCH community:

${\mathrm{tl}}_{inew}=\frac{{\mathrm{tl}}_{i900\_band}*c_{i900new}+({\mathrm{tl}}_{i1800\_band}-Load\_t\arg et\_Cell\_\mathrm{1800+}Load\_t\arg et\_Cell\_9\mathrm{00})*c_{i1800new}}{(c_{i900new}+c_{i1800new})}$

Wherein tl_{i900_band}, tl_{i1800_band}For 900M, 1800M at total expection telephone traffic peak hour respective every line traffic Amount；Local_target_cell_900 is " load target value that 900M community is corresponding "；Local_target_cell_1800 is " load target value that 1800M community is corresponding "；

Step 8: equilibrium object community selects, according to selected Different Strategies, analyzes business statistics Zhong Mei community and bears Lotus data or congestion data, sieves selects the object community needing outwards to share business；

User is needed to specify equalizing traffic volume algorithm policy: " alleviating congested ", " general equilibrium "；

As selected " alleviating congested ", then have only to select to there is congested community, i.e. congestion ratio more than congestion threshold value Community, as equalizing traffic volume optimization object；

As selected " general equilibrium ", then according to adjustable parameters " the unbalanced thresholding of the traffic " TRAFFIC_ set UNBALANCE_THRESHOLD filters selection:

Equalizing traffic volume coefficient T affic_Balance_Factor_iThe community of ＞ TRAFFIC_UNBALANCE_THRESHOLD As equalizing traffic volume optimization object；

Each object community, is also performed to repeater and zooms out station filtration, and object community is as hung repeater or having zoomed out the most simultaneously Standing, i.e. " cell configuration table .Repeater=Y ", Ze Gai community is removed from object cell list, recorded that " band is directly put simultaneously Stand congested cell " list；

Step 9: need to equalize telephone traffic calculate, according to selected strategy, calculate each object community need share if Business amount；

To community each in optimization object list, calculate it and need to equalize telephone traffic:

Traffic_Out_i=c_i*(tl_i-Load_target_cell_900)

Wherein: tl_iFor line telephone traffic every during busy cells, c_iFor this cell configuration number of channel；

By Traffic_Out_i< community of 0 is removed from list object, and output recorded, and " underload congested cell arranges Table " in；

Step 10: equalization target cell filtering identification, from the adjacent area that each object subdistrict position is adjacent, filters out permissible For sharing the Target cell of object Zone；

Equalization target cell filtering thresholding TRAFFIC_INCOMING_THRESHOLD need to be defined, it is proposed that value be "- 0.5 ",

From list in the adjacent adjacent area, geographical position of each object community, according to:

(1) it is adjacent adjacent area, geographical position, object community,

And meet Taffic_Balance_Factor (2)_iThe condition of ＜ TRAFFIC_INCOMING_THRESHOLD, mistake Filtering and export can be as the cell list of equalizing traffic volume target；

Step 11: equalization target ranking cells, according to Target cell with object community relative to position, band information, to all Weighing apparatus Target cell is ranked up；

Need to set a sector minimum angle threshold parameter, target cell list is arranged by MIN_ANGLE_SECTOR Sequence:

Wherein:

(1) Target cell priority Object_Antenna_Priority=1 of sector alien frequencies it is total to；

(2) the Target cell priority of adjacent adjacent area, geographical position each other

Object_Antenna_Priority=2；

(3) Target cell and object community are with the same frequency range of longitude and latitude, need to carry out number of sectors inspection, if this longitude and latitude With frequency number of sectors more than 3, then need to calculate between each same frequency sector and object community:

4sector_angle_n=MOD ((360+Direction_CoSite_Cell_n-Direction_Object_ Cell), 360)；

Wherein: Direction_CoSite_Cell_n is the azimuth of common longitude and latitude co-frequency cell；

It addition, Target cell to be calculated and object community angle:

4sector_angle_target=MOD ((360+Direction_Target_Cell Direction_ Object_Cell), 360)

Wherein: Direction_Target_Cell is Target cell azimuth；

If Target cell meets with the angle 4sector_angle_target of object community

MIN (4sector_angle_n) < 4sector_angle_target < Max (4sector_angle_n) will Target cell identification is non-adjacent with frequency longitude and latitude community altogether, and gives up, and removes from target cell list；

As being unsatisfactory for, then retain this Target cell and proceed follow-up judgement:

(1) with object community with the same frequency range of longitude and latitude, and MIN (abs (Direction_Target_Cell- Direction_Object_Cell),abs(360+Direction_Target_Cell-Direction_Object_Cell))> MIN_ANGLE_SECTOR

Or with longitude and latitude alien frequencies section but be not total to sector with object community, and MIN (abs (Direction_Target_Cell- Direction_CoSector_DifBand),abs(360+Direction_Target_Cell-Direction_CoSector_ DifBand)) > Target cell priority Object_Antenna_Priority=3 of MIN_ANGLE_SECTOR；

Wherein: Direction_CoSector_DifBand is with longitude and latitude alien frequencies end but not to be total to sector with object community Azimuth；

(2) other Target cell priority Object_Antenna_Priority=4；

(3) with object community with longitude and latitude with frequency range and MIN (abs (Direction_Target_Cell-Direction_ Object_Cell), abs (360+Direction_Target_Cell-Direction_Object_Cell))≤MIN_ The Target cell of ANGLE_SECTOR is removed from list；

(4) with longitude and latitude alien frequencies section but sector it is not total to object community, and MIN (abs (Direction_Target_ Cell-Direction_CoSector_DifBand),abs(360+Direction_Target_Cell-Direction_ The Target cell of CoSector_DifBand))≤MIN_ANGLE_SECTOR is removed from list；

(5) traffic bearing capacity can the Target cell of Bearing capacity of call service thresholding less than Target cell；Remove from list；

(6) each Target cell, will carry out wireless discharging-directly station/zoom out station and filter, hang such as Target cell wireless simultaneously Repeater or zoom out station, Ze Gai community is labeled as " repeater information source cell "；Priority Object_Antenna_Priority number Being worth little person, sequence is front；

Step 12: the equalization target community ability of equalization calculates, and according to selected strategy, calculates each Target cell most The telephone traffic that can share；

To target cell list after sequence, calculate each Target cell respectively can the Bearing capacity of call service:

Traffic_Incoming_Cap_in=c_in*(Load_target_cell_900-tl_in

Wherein c_in, tl_inFor i-th object community the n-th Target cell configurating channel number and expect every line traffic Amount；

According to Target cell ability of equalization inverted order, to each priority Object_Antenna_Priority community again Sequence；

Step 13: the new azimuthal angle calculation in equalization target community, according to object community and the longitude and latitude of Target cell, frequency range, Calculate Target cell and share the optimum azimuth of object Zone；

With the Target cell of object community different longitude and latitude, need to calculate its relative position relation:

Identifying that Target cell longitude and latitude is (x1, y1), object community longitude and latitude is (x2, y2)；

Calculate Target cell to line azimuth, object community Angle_Object_to_Target:

$Angle\_Object\_to\_T\arg et=\frac{180}{\mathrm{\&pi;}}*MOD\left(arctan\right(\frac{x2-x1}{y2-y1})+2\mathrm{\&pi;}+arccos(\frac{abs(y2-y1)}{y2-y1}),2\mathrm{\&pi;})$

Wherein: MOD () is for taking remainder operation, and arctan () is arctangent cp cp operation, and arccos () is anticosine computing；

Modifiable parameter is set: estimate cell serves radius ExpectCellRadius=300m；

As " Zone statistical table. average TA " be not empty, then cell serves radius CellRadius=AverageTA* 275

As " Zone statistical table. average TA " be empty, then cell serves radius CellRadius= ExpectCellRadius

Wherein: AverageTA is the data obtained in system business statistical data；

A, Target cell and object community different longitude and latitude

According to the angle Angle_Object_to_Target calculated, object community can be calculated to Target cell line Azimuth:

Angle_Target_to_Object=MOD (Angle_Object_to_Target+180,360)

Need each Target cell being checked, whether it is the sector pointing to object community:

Calculating with Target cell with longitude and latitude with all sectors of frequency range, Target cell should meet:

MIN(abs(Direction_Target_Cell-Angle_Object_to_Target),abs(360+ Direction_Target_Cell-Angle_Object_to_Target))≤MIN

(MIN(abs(Direction_Target_Other_Cell1-Angle_Object_to_Target),abs(360 + Direction_Target_Other_Cell1-Angle_Object_to_Target)),

MIN(abs(Direction_Target_Other_Cell2-Angle_Object_to_Target),abs(360+ Direction_Target_Other_Cell2-Angle_Object_to_Target)))

Wherein Direction_Target_Other_Cell1, Direction_Target_Other_Cell2 are and target Community with longitude and latitude with other communities of frequency range；

As met above-mentioned condition, continue subsequent calculations, otherwise, from target cell list, directly remove this Target cell；

Target cell optimum azimuth (1) is:

$\begin{array}{c}Direction\_T\arg et\_Best1=Angle\_Object\_to\_T\arg et-\frac{HPBW}{2}*\\ \frac{ABS(Direction\_Object\_Cell-Angle\_T\arg et\_to\_Object)}{(Direction\_Object\_Cell-Angle\_T\arg et\_to\_Object)}\end{array}$

If Direction_Object_Cell-Angle_Target_to_Object=0

Then Direction_Target_Best1=Mod (Angle_Object_to_Target+360,360)

Wherein HPBW is Target cell antenna half-power angle；

Target cell optimum azimuth (2) computational methods are:

AvgLat=(y1+y2)/2

LatDistance=110946.3

$LonDis\tan ce=111320*cos(\frac{\mathrm{\&pi;}}{180}*AvgLat)$

$\begin{array}{c}Direction\_T\arg et\_Best2\\ =\frac{\mathrm{\&pi;}}{180}*MOD(arctan\left(\frac{Lon\mathrm{Re}f-x1}{Lat\mathrm{Re}f-y1}\right)+2\mathrm{\&pi;}\\ +arccos\left(\frac{abs(Lon\mathrm{Re}f-y1}{Lat\mathrm{Re}f-y1}\right),2\mathrm{\&pi;})\end{array}$

Respectively calculate two optimum azimuth Direction_Target_Best1, Direction_Target_Best2 with The angle of Angle_Object_to_Target,

Angle calcu-lation method is:

Angle1=acos (cos ((Direction_Target_Best1-Angle_Object_to_Target) * π/ 180))*180/π

Angle2=acos (cos ((Direction_Target_Best2-Angle_Object_to_Target) * π/ 180))*180/π

Taking Direction_Target_Best1, one that in Direction_Target_Best2, corresponding angle is little is Whole Direction_Target_Best；

That is:

Such as Angle1 >=Angle2,

Then Direction_Target_Best=Direction_Target_Best1,

Otherwise Direction_Target_Best=Direction_Target_Best2

B, Target cell are identical with longitude and latitude and frequency range with object community

Such as sin (180/ π * (Direction_Target_Cell-Direction_Object_Cell) > 0 Target cell Optimum azimuth be:

Direction_Target_Best=MOD ((Direction_Object_Cell+MIN_ANGLE_SECTOR), 360)

Such as sin (180/ π * (Direction_Target_Cell-Direction_Object_Cell) < 0 Target cell Optimum azimuth be:

Direction_Target_Best=MOD ((360+Direction_Object_Cell-MIN_ANGLE_ SECTOR), 360)

Such as sin (180/ π * (Direction_Target_Cell-Direction_Object_Cell)=0

Then also need to be judged by the azimuth of another one sector again,

Such as sin (180/ π * (Direction_Cosite_Cell-Direction_Object_Cell) > 0

Then Direction_Target_Best=MOD ((360+Direction_Object_Cell-MIN_ANGLE_ SECTOR), 360)

Wherein, Direction_Cosite_Cell is with the same frequency of longitude and latitude with object community, but different from Target cell The azimuth of sector

Such as sin (180/ π * (Direction_Cosite_Cell-Direction_Object_Cell) < 0

Direction_Target_Best=MOD ((Direction_Object_Cell+MIN_ANGLE_SECTOR), 360)；

C, with sector alien frequencies section Target cell

Optimum azimuth with sector alien frequencies section Target cell should be identical with object community with optimal angle of declination:

Direction_Target_Best=Direction_Object_Cell

Downtilt_Target_Best=Downtilt_Object_Cell

D, Target cell are from object community with longitude and latitude different sector alien frequencies section, and object community with sector alien frequencies section is simultaneously If Target cell: be Target cell with alien frequencies section community, sector simultaneously, then the tested rotating platform scheme of other alien frequencies section communities is:

Such as sin (180/ π * (Direction_Target_Cell-Direction_Object_Cell)) > 0

Then the optimum azimuth of Target cell is:

Direction_Target_Best=MOD ((Direction_Object_Cell+MIN_ANGLE_SECTOR), 360)

Such as sin (180/ π * (Direction_Target_Cell-Direction_Object_Cell) < 0

Then the optimum azimuth of Target cell is:

Direction_Target_Best=MOD ((360+Direction_Object_Cell-MIN_ANGLE_ SECTOR), 360)

Such as sin (180/ π * (Direction_Target_Cell-Direction_Object_Cell))=0

Then also need to be judged by the azimuth of another one sector again

Such as sin (180/ π * (Direction_Cosite_Cell-Direction_Object_Cell)) > 0

Then Direction_Target_Best=MOD ((360+Direction_Object_Cell-MIN_ANGLE_ SECTOR), 360)

As sin (180/ π * (Direction_Cosite_Cell-Direction_Object_Cell)) < 0Direction_Target_Best=MOD ((Direction_Object_Cell+MIN_ANGLE_SECTOR), 360)；

E, Target cell and object community, with longitude and latitude different sector alien frequencies section, are not that target is little with sector alien frequencies section simultaneously District

If: be not Target cell with alien frequencies section community, sector, then the tested rotating platform scheme of other alien frequencies section communities is:

Such as sin (180/ π * (Direction_Target_Cell-Direction_CoSector_DifBand) > 0 mesh The optimum azimuth of mark community is:

Direction_Target_Best=MOD ((Direction_CoSector_DifBand+MIN_ANGLE_ SECTOR), 360)

Such as sin (180/ π * (Direction_Target_Cell-Direction_CoSector_DifBand) < 0

Then the optimum azimuth of Target cell is:

Direction_Target_Best=MOD ((360+Direction_CoSector_DifBand-MIN_ANGLE_ SECTOR), 360)

Such as sin (180/ π * (Direction_Target_Cell-Direction_CoSector_DifBand)=0

Then also need to be judged by the azimuth of another one sector again

Such as sin (180/ π * (Direction_Cosite_DifBand_Cell-Direction_CoSector_ DifBand)>0

Then Direction_Target_Best=MOD ((360+Direction_CoSector_DifBand-MIN_ ANGLE_SECTOR), 360)

Such as sin (180/ π * (Direction_Cosite_DifBand_Cell-Direction_CoSector_ DifBand)<0

Direction_Target_Best=MOD ((Direction_CoSector_DifBand+MIN_ANGLE_ SECTOR), 360)

Wherein, Direction_Cosite_DifBand_Cell is the azimuth of another one sector；

Export the optimum apjustment azimuth Direction_Target_Best of each Target cell；

Step 14: related adjustment cell identification and azimuthal angle calculation, it is judged that be with other communities of Target cell colocation site No need to occur related adjustment, and calculate the azimuth of related adjustment community；

After calculating Target cell optimum apjustment azimuth Direction_Target_Best, also need according to its same longitude and latitude Scheme is modified by adjacent area situation:

Such as Target cell and object community different longitude and latitude, revision of option method is as follows:

If 1. (180/ π * (Direction_Target_Best-Direction_Target_Cell) > 0 is then sin Adjust clockwise

Now to Target cell with longitude and latitude with other sectors of frequency range, all need to meet one of condition A or B:

A, works as Direction_Target_Other_Cell-Direction_Target_Cell > 0

Meet (Direction_Target_Best+MIN_ANGLE_SECTOR) < Direction_Target_Other_ Cell

Target cell azimuth is then only had to need to adjust to Direction_Target_Best

Direction_Target_Other_Cell be Target cell with longitude and latitude with frequency range sector azimuth angle

Otherwise, be unsatisfactory for the same longitude and latitude sector of condition with frequency range be also required to be adjusted to

Direction_Target_Other_New=MOD ((Direction_Target_Best+360+MIN_ANGLE_ SECTOR), 360)

Direction_Target_Other_New need to adjust new azimuth for being unsatisfactory for condition with frequency range sector

B, as Direction_Target_Other_Cell-Direction_Target_Cell < 0

Meet (Direction_Target_Best+MIN_ANGLE_SECTOR) < Direction_Target_Other_ Cell+360

Target cell azimuth is then only had to need to adjust to Direction_Target_Best

Otherwise, be unsatisfactory for the same longitude and latitude of condition with frequency range sector be also required to be adjusted to

Direction_Target_Other_New=MOD ((Direction_Target_Best+360+MIN_ANGLE_ SECTOR), 360)

If 2. sin (180/ π * (Direction_Target_Best-Direction_Target_Cell) < 0,

Then Target cell is to adjust counterclockwise

Now to Target cell with longitude and latitude with other sectors of frequency range, all need to meet one of condition C or D:

C, as Direction_Target_Other_Cell-Direction_Target_Cell < 0

Meet (Direction_Target_Best-MIN_ANGLE_SECTOR) Direction_Target_Other_ Cell

Target cell azimuth is then only had to need to adjust to Direction_Target_Best

Otherwise, be unsatisfactory for the same longitude and latitude of condition with frequency range sector be also required to be adjusted to

Direction_Target_Other_New=MOD ((Direction_Target_Best+360-MIN_ANGLE_ SECTOR), 360)

D, works as Direction_Target_Other_Cell-Direction_Target_Cell > 0

Meet MOD (Direction_Target_Best+360-MIN_ANGLE_SECTOR) > Direction_Target_ Other_Cell

Target cell azimuth is then only had to need to adjust to Direction_Target_Best

Otherwise, be unsatisfactory for the same longitude and latitude of condition with frequency range sector be also required to be adjusted to

Direction_Target_Other_New=MOD ((Direction_Target_Best+360-MIN_ANGLE_ SECTOR), 360)

Step 15: tested rotating platform EFFECTIVENESS ESTIMATION, according to tested rotating platform amplitude, estimates that each Target cell adjusts possible Sharing effect, the tested rotating platform scheme obtained, if the amplitude of adjustment is too small, it is clear that effect will not be clearly；It is thus desirable to it is right Possible being predicted property of effect assessment；

Constant with the Object_Antenna_Priority of sector alien frequencies Target cell is 1.

To remaining each Target cell calculating adjustment amplitude:

Adjust_Angle=MIN (ABS (Direction_Target_Best-Direction_Target_Cell), ABS(Direction_Target_Best-Direction_Target_Cell+360))

Effect is set and judges threshold parameter: ADJUST_RESULT_THRESHOLD=10

Such as Target cell Adjust_Angle < ADJUST_RESULT_THRESHOLD,

Then judging " expected effects is the least ", this Target cell priority Object_Antenna_Priority is reduced 4；

Such as Target cell ADJUST_RESULT_THRESHOLD=< Adjust_Angle < 2*ADJUST_RESULT_ THRESHOLD,

Then judge " expected effects is the most notable ", this Target cell priority Object_Antenna_Priority=max (Object_Antenna_Priority+1,6)；

Such as Target cell 2*ADJUST_RESULT_THRESHOLD≤Adjust_Angle

Then judge " expected effects is notable ", this Target cell priority Object_Antenna_Priority= (Object_Antenna_Priority-1,1)；

Step 16: tested rotating platform collision detection and coordination, after the calculating of the whole network all objects community completes, identifies same Time be the Target cell of multiple object community, according to adjusting priority, it is carried out preferentially by the ability of equalization, EFFECTIVENESS ESTIMATION result Level adjusts；

Target cell in the final output listing of tested rotating platform of output, carries out collision detection；Tested rotating platform punching need to be set Prominent mark Conflict_Flag；

When there is multiple object community, to each Target cell of output in step 10, add up it little at whole objects The number of times Target_Cell_Count occurred in district's output object listing；

Such as Target_Cell_Count > 1, revise the Conflict_Flag of this Target cell corresponding record all the most simultaneously =1；

Relatively this Target cell priority Object_Antenna_Priority in its each list occurred, excellent The priority of first value of series minimum keeps constant, by this Target cell Object_Antenna_Priority=in other lists max(Object_Antenna_Priority+2,6)；

As this Target cell is identical at multiple list medium priorities, then compare and these lists remove outside this Target cell, Minimum priority MIN (Object_Antenna_Priority_n) of other Target cells, keeps the priority that this numerical value is maximum Constant, by this Target cell Object_Antenna_Priority=max (Object_Antenna_ in other lists Priority+2,6)；

As above-mentioned minima there is also multiple identical, the telephone traffic to be equalized of object community corresponding to the most each list TRAFFIC_OUT, the priority keeping this numerical value maximum is constant, by this Target cell Object_Antenna_ in other lists Priority=max (Object_Antenna_Priority+1,6)；

Step 17: equilibrium community is compared with Target cell parameter is little with target to every pair of equilibrium community according to preset rules The parameters such as switching between district, adjacent area, community access compare, and provide tendency and adjust suggestion；

Parameter comparable situation between each Target cell and object community in sorted lists, and become according to preset rules Gesture is analyzed；It is presently contemplated that two class parameters:

(1) adjacent area level parameter

Such as: the two-way adjacent area level parameter of HOmargin, HO priority etc；

Need unified predefined regular:

A, two-way equal (or difference is less than certain pre-determined threshold): be judged as " currently without substantially tendency, having certain adjustment remaining Ground "；Priority Object_ADJPar_Priority=2

B, forward big (difference is more than thresholding): be judged as " current existing substantially tendency, adjust leeway the least "；Priority Object_ADJPar_Priority=3

C, forward little (difference is more than thresholding): be judged as " currently having obvious phase countertendency, adjust leeway the biggest "；Priority Object_ADJPar_Priority=1

Above-mentioned three kinds of comparative results, and three kinds of conclusions are the most predeterminable good, user select to be combined；I.e. some parameter can Can be " forward is big, without adjusting leeway ", other parameter can also be " forward is little, without adjusting leeway "；

(2) cell-level parameter

Cell-level parameter does not has directivity, itself can only analyze from community but it also may sum up similar conclusion:

A, Target cell parameter arranges height (greatly): be judged as " Target cell absorbs traffic trend, consistent with equalization requirement, Adjust leeway the least " priority Object_CellPar_Priority=3；

B, Target cell parameter is arranged low (little): be judged as that " Target cell releases traffic trend, differs with equalization requirement Cause, adjust leeway the biggest " priority Object_CellPar_Priority=1；

C, Target cell parameter arranges identical: be judged as " currently without substantially tendency, have and necessarily adjust leeway " priority Object_CellPar_Priority=2；

Each Target cell is calculated its equalization parameter priority

Object_Parameter_Priority=Object_CellPar_Priority+Object _ ADJPar_ Priority

Output: the target cell list after sorting according to equalization parameter priority Object_Parameter_Priority； The little person of numerical value sorts front；

Comparison procedure

1, " cell parameter table " and " adjacent area parameter list " the statistical parameter quantity to input, is designated as " cell parameter number "

" adjacent area number of parameters "；

2, " number of parameters is compared "=" cell parameter number "+" adjacent area number of parameters "；

3, according to above-mentioned predefined rule, perform to compare to each parameter respectively, according to " Rule of judgment " result, export phase " Object_CELLPar_Priority " answered, and recorded " parameter compares detailed results " respectively and " parameter compares conclusion Table " respective column；

Each Target cell is calculated its " equalization parameter priority ": Object_Parameter

_ Priority=(Object_CellPar_Priority+Object_ADJPar_Priority)/compare parameter Number

And recorded the respective column of " parameter compares conclusion table "；

4, according to the Object_Parameter_Priority numerical value calculated, generating conclusion, rule is as follows:

Object_Parameter_Priority >=2.5, conclusion is that " Target cell absorbs traffic trend, needs with Jun Heng Ask consistent, adjust leeway the least "；

2.5 > Object_ADJPar_Priority >=1.5, conclusion is " currently without substantially tendency, to have more than certain adjustment Ground "

1.5 > Object_ADJPar_Priority, conclusion is that " Target cell releases traffic trend, differs with equalization requirement Cause, adjust leeway the biggest "；And conclusion be recorded " conclusion " row of " parameter compares conclusion table "；

5, such as Object_Parameter_Priority >=2.5, then this Target cell is met with object cell combination Field name corresponding to Object_CellPar_Priority=3, Object_ADJPar_Priority=3 (RXP, PMRG；；；) read, after being merged into character string, recorded in " suggestion the adjusts parameter " field in " parameter compares conclusion table "；

Step 18: collect output equalization scheme, according to tested rotating platform, configuration adjustment, parameter adjustment proposed projects, collects defeated Go out overall equalization scheme；According to above steps result of calculation, the adjacent neighbour in all geographical position to each object community respectively District carries out overall sequence, generates integrated ordered list；And according to being output as overall equalization scheme suggestion after prioritization.

Step 8: equilibrium object community selects, according to selected Different Strategies, analyzes the every cell load number in business statistics According to or congestion data, sieves is selected needs outwards to share the object community of business；

User is needed to specify equalizing traffic volume algorithm policy: " alleviating congested ", " general equilibrium "；

As selected " alleviating congested ", then have only to the community selecting to there is congested community, i.e. congestion ratio more than congestion threshold value, As equalizing traffic volume optimization object；

As selected " general equilibrium ", then according to adjustable parameters " the unbalanced thresholding of the traffic " TRAFFIC_UNBALANCE_ set THRESHOLD filters selection:

Equalizing traffic volume coefficient T affic_Balance_Factor_iThe community conduct of ＞ TRAFFIC_UNBALANCE_THRESHOLD Equalizing traffic volume optimization object；

Each object community, is also performed to repeater and zooms out station filtration, and object community is as hung repeater or having zoomed out station, i.e. the most simultaneously " cell configuration table .Repeater=Y ", Ze Gai community is removed from object cell list, recorded that " band repeater is congested simultaneously Community " list；

Step 9: need to equalize telephone traffic and calculate, according to selected strategy, calculates the telephone traffic that each object community needs to share；

To community each in optimization object list, calculate it and need to equalize telephone traffic:

Traffic_Out_i=c_i*(tl_i-Load_target_cell_900)

Wherein: tl_iFor line telephone traffic every during busy cells, c_iFor this cell configuration number of channel；

By Traffic_Out_i< community of 0 is removed from list object, and output recorded in " list of underload congested cell "；

Step 10: equalization target cell filtering identification, from the adjacent area that each object subdistrict position is adjacent, filters out and may be used for Share the Target cell of object Zone；

Equalization target cell filtering thresholding TRAFFIC_INCOMING_THRESHOLD need to be defined, it is proposed that value is "-0.5 ",

From list in the adjacent adjacent area, geographical position of each object community, according to:

(1) it is adjacent adjacent area, geographical position, object community,

And meet Taffic_Balance_Factor (2)_iThe condition of ＜ TRAFFIC_INCOMING_THRESHOLD, filters and defeated Going out can be as the cell list of equalizing traffic volume target；

Step 11: equalization target ranking cells, according to Target cell with object community relative to position, band information, to equilibrium mesh Mark community is ranked up；

Need to set a sector minimum angle threshold parameter, target cell list is ranked up by MIN_ANGLE_SECTOR:

Wherein:

(1) Target cell priority Object_Antenna_Priority=1 of sector alien frequencies it is total to；

(2) the Target cell priority of adjacent adjacent area, geographical position each other

Object_Antenna_Priority=2；

(3) Target cell and object community are with the same frequency range of longitude and latitude, need to carry out number of sectors inspection, if this longitude and latitude is with frequency Number of sectors more than 3, then needs to calculate between each same frequency sector and object community:

4sector_angle_n=MOD ((360+Direction_CoSite_Cell_n-Direction_Object_Cell), 360)；

Wherein: Direction_CoSite_Cell_n is the azimuth of common longitude and latitude co-frequency cell；

It addition, Target cell to be calculated and object community angle:

4sector_angle_target=MOD ((360+Direction_Target_Cell Direction_Object_ Cell), 360)

If Target cell meets with the angle 4sector_angle_target of object community

MIN (4sector_angle_n) < 4sector_angle_target < Max (4sector_angle_n) will this target Cell identification is non-adjacent with frequency longitude and latitude community altogether, and gives up, and removes from target cell list；

As being unsatisfactory for, then retain this Target cell and proceed follow-up judgement:

(1) with object community with the same frequency range of longitude and latitude, and MIN (abs (Direction_Target_Cell-Direction_ Object_Cell),abs(360+Direction_Target_Cell-Direction_Object_Cell))>MIN_ANGLE_ SECTOR

Or with longitude and latitude alien frequencies section but be not total to sector with object community, and MIN (abs (Direction_Target_Cell- Direction_CoSector_DifBand),abs(360+Direction_Target_Cell-Direction_CoSector_ DifBand)) > Target cell priority Object_Antenna_Priority=3 of MIN_ANGLE_SECTOR；

Wherein: Direction_CoSector_DifBand is with longitude and latitude alien frequencies end but not to be total to the orientation of sector with object community Angle；

(2) other Target cell priority Object_Antenna_Priority=4；

(3) with object community with longitude and latitude with frequency range and MIN (abs (Direction_Target_Cell-Direction_ Object_Cell), abs (360+Direction_Target_Cell-Direction_Object_Cell))≤MIN_ The Target cell of ANGLE_SECTOR is removed from list；

(4) with longitude and latitude alien frequencies section but sector it is not total to object community, and MIN (abs (Direction_Target_Cell- Direction_CoSector_DifBand),abs(360+Direction_Target_Cell-Direction_CoSector_ The Target cell of DifBand))≤MIN_ANGLE_SECTOR is removed from list；

(5) traffic bearing capacity can the Target cell of Bearing capacity of call service thresholding less than Target cell；Remove from list；

(6) each Target cell, will carry out wireless discharging-directly station/zoom out station and filter, and has hung such as Target cell simultaneously and wireless has directly put Standing or zoom out station, Ze Gai community is labeled as " repeater information source cell "；Priority Object_Antenna_Priority numerical value is little Person, sequence is front；

Step 12: the equalization target community ability of equalization calculates, and according to selected strategy, calculates each Target cell the most permissible The telephone traffic shared；

To target cell list after sequence, calculate each Target cell respectively can the Bearing capacity of call service:

Traffic_Incoming_Cap_in=c_in*(Load_target_cell_900-tl_in

Wherein c_in, tl_inFor i-th object community the n-th Target cell configurating channel number and expect every line telephone traffic；

According to Target cell ability of equalization inverted order, is resequenced in each priority Object_Antenna_Priority community；

Step 13: the new azimuthal angle calculation in equalization target community, according to object community and the longitude and latitude of Target cell, frequency range, calculates Go out Target cell and share the optimum azimuth of object Zone；

With the Target cell of object community different longitude and latitude, need to calculate its relative position relation:

Identifying that Target cell longitude and latitude is (x1, y1), object community longitude and latitude is (x2, y2)；

Calculate Target cell to line azimuth, object community Angle_Object_to_Target:

$Angle\_Object\_to\_T\arg et=\frac{180}{\mathrm{\&pi;}}*MOD\left(\arctan \right(\frac{x2-x1}{y2-y1})+2\mathrm{\&pi;}+\arccos (\frac{abs(y2-y1)}{y2-y1}),2\mathrm{\&pi;})$

Wherein: MOD () is for taking remainder operation, and arctan () is arctangent cp cp operation, and arccos () is anticosine computing；

Modifiable parameter is set: estimate cell serves radius ExpectCellRadius=300m；

As " Zone statistical table. average TA " be not empty, then cell serves radius CellRadius=AverageTA*275

As " Zone statistical table. average TA " be empty, then cell serves radius CellRadius=ExpectCellRadius

Wherein: AverageTA is the data obtained in system business statistical data；

A, Target cell and object community different longitude and latitude

According to the angle Angle_Object_to_Target calculated, the orientation to Target cell line, the object community can be calculated Angle:

Angle_Target_to_Object=MOD (Angle_Object_to_Target+180,360)

Need each Target cell being checked, whether it is the sector pointing to object community:

Calculating with Target cell with longitude and latitude with all sectors of frequency range, Target cell should meet:

MIN(abs(Direction_Target_Cell-Angle_Object_to_Target),abs(360+Direction_ Target_Cell-Angle_Object_to_Target))≤MIN (MIN (abs (Direction_Target_Other_ Cell 1-Angle_Object_to_Target),abs(360+Direction_Target_Other_Cell 1-Angle_ Object_to_Target)), MIN (abs (Direction_Target_Other_Cell2-Angle_Object_to_ Target),abs(360+Direction_Target_Other_Cell2-Angle_Object_to_Target)))

Wherein Direction_Target_Other_Cell1, Direction_Target_Other_Cell2 are and Target cell With longitude and latitude with other communities of frequency range；

As met above-mentioned condition, continue subsequent calculations, otherwise, from target cell list, directly remove this Target cell；

Target cell optimum azimuth (1) is:

$\begin{array}{c}Direction\_T\arg et\_Best1=Angle\_Object\_to\_T\arg et-\frac{HPBW}{2}*\\ \frac{ABS(Direction\_Object\_Cell-Angle\_T\arg et\_to\_Object)}{(Direction\_Object\_Cell-Angle\_T\arg et\_to\_Object)}\end{array}$

If Direction_Object_Cell-Angle_Target_to_Object=0

Then Direction_Target_Best1=Mod (Angle_Object_to_Target+360,360)

Wherein HPBW is Target cell antenna half-power angle；

Target cell optimum azimuth (2) computational methods are:

AvgLat=(y1+y2)/2

LatDistance=110946.3

$LonDis\tan ce=111320*cos(\frac{\mathrm{\&pi;}}{180}*AvgLat)$

$\begin{array}{c}Direction\_T\arg et\_Best2\\ =\frac{\mathrm{\&pi;}}{180}*MOD(\arctan \left(\frac{Lon\mathrm{Re}f-x1}{Lat\mathrm{Re}f-y1}\right)+2\mathrm{\&pi;}\\ +\arccos (\frac{abs(Lat\mathrm{Re}f-y1)}{Lat\mathrm{Re}f-y1},2\mathrm{\&pi;})\end{array}$

Respectively calculate two optimum azimuth Direction_Target_Best1, Direction_Target_Best2 with The angle of Angle_Object_to_Target,

Angle calcu-lation method is:

Angle1=acos (cos ((Direction_Target_Best1-Angle_Object_to_Target) * π/180)) * 180/π

Angle2=acos (cos ((Direction_Target_Best2-Angle_Object_to_Target) * π/180)) * 180/π

Taking Direction_Target_Best1, one that in Direction_Target_Best2, corresponding angle is little is final Direction_Target_Best；

That is:

Such as Angle1 >=Angle2,

Then Direction_Target_Best=Direction_Target_Best1,

Otherwise Direction_Target_Best=Direction_Target_Best2

B, Target cell are identical with longitude and latitude and frequency range with object community

Such as sin, (180/ π * (Direction_Target_Cell-Direction_Object_Cell) > 0 Target cell is Good azimuth is:

Direction_Target_Best=MOD ((360+Direction_Object_Cell-MIN_ANGLE_SECTOR), 360)

Such as sin, (180/ π * (Direction_Target_Cell-Direction_Object_Cell)=0 item also needs to lead to again The azimuth crossing another one sector judges,

Such as sin (180/ π * (Direction_Cosite_Cell-Direction_Object_Cell) > 0

Then Direction_Target_Best=MOD ((360+Direction_Object_Cell-MIN_ANGLE_ SECTOR), 360)

Wherein, Direction_Cosite_Cell is with the same frequency of longitude and latitude with object community, but the sector different from Target cell Azimuth

Such as sin (180/ π * (Direction_Cosite_Cell-Direction_Object_Cell) < 0

Direction_Target_Best=MOD ((Direction_Object_Cell+MIN_ANGLE_SECTOR), 360)；

C, with sector alien frequencies section Target cell

Optimum azimuth with sector alien frequencies section Target cell should be identical with object community with optimal angle of declination:

Direction_Target_Best=Direction_Object_Cell

Downtilt_Target_Best=Downtilt_Object_Cell

D, Target cell are from object community with longitude and latitude different sector alien frequencies section, and object community is target with sector alien frequencies section simultaneously If community: be Target cell with alien frequencies section community, sector simultaneously, then the tested rotating platform scheme of other alien frequencies section communities is:

Such as sin (180/ π * (Direction_Target_Cell-Direction_Object_Cell)) > 0 item Target cell Optimum azimuth is:

Direction_Target_Best=MOD ((Direction_Object_Cell+MIN_ANGLE_SECTOR), 360)

Such as sin, (180/ π * (Direction_Target_Cell-Direction_Object_Cell) < 0 Target cell is Good azimuth is:

Direction_Target_Best=MOD ((360+Direction_Object_Cell-MIN_ANGLE_SECTOR), 360)

Such as sin (180/ π * (Direction_Target_Cell-Direction_Object_Cell))=0

Then also need to be judged by the azimuth of another one sector again

Such as sin (180/ π * (Direction_Cosite_Cell-Direction_Object_Cell)) > 0

Then Direction_Target_Best=MOD ((360+Direction_Object_Cell-MIN_ANGLE_ SECTOR), 360)

Such as sin (180/ π * (Direction_Cosite_Cell-Direction_Object_Cell)) < 0Direction_ Target_Best=MOD ((Direction_Object_Cell+MIN_ANGLE_SECTOR), 360)；

E, Target cell and object community, with longitude and latitude different sector alien frequencies section, are not Target cells with sector alien frequencies section simultaneously

If: be not Target cell with alien frequencies section community, sector, then the tested rotating platform scheme of other alien frequencies section communities is:

Such as sin (180/ π * (Direction_Target_Cell-Direction_CoSector_DifBand) > 0

Then the optimum azimuth of Target cell is:

Direction_Target_Best=MOD ((Direction_CoSector_DifBand+MIN_ANGLE_SECTOR), 360)

Such as sin (180/ π * (Direction_Target_Cell-Direction_CoSector_DifBand) < 0

Then the optimum azimuth of Target cell is:

Direction_Target_Best=MOD ((360+Direction_CoSector_DifBand-MIN_ANGLE_ SECTOR), 360)

Such as sin (180/ π * (Direction_Target_Cell-Direction_CoSector_DifBand)=0

Then also need to be judged by the azimuth of another one sector again

Such as sin (180/ π * (Direction_Cosite_DifBand_Cell-Direction_CoSector_DifBand) > 0

Then Direction_Target_Best=MOD ((360+Direction_CoSector_DifBand-MIN_ANGLE_ SECTOR), 360)

Such as sin (180/ π * (Direction_Cosite_DifBand_Cell-Direction_CoSector_DifBand) < 0

Direction_Target_Best=MOD ((Direction_CoSector_DifBand+MIN_ANGLE_SECTOR), 360)

Wherein, Direction_Cosite_DifBand_Cell is the azimuth of another one sector；

Export the optimum apjustment azimuth Direction_Target_Best of each Target cell；

Step 14: related adjustment cell identification and azimuthal angle calculation, it is judged that whether need with other communities of Target cell colocation site There is related adjustment, and calculate the azimuth of related adjustment community；

After calculating Target cell optimum apjustment azimuth Direction_Target_Best, also need according to it with longitude and latitude adjacent area Scheme is modified by situation:

Such as Target cell and object community different longitude and latitude, revision of option method is as follows:

If 1. (180/ π * (Direction_Target_Best-Direction_Target_Cell) > 0 is then up time to sin Pin adjusts

Now to Target cell with longitude and latitude with other sectors of frequency range, all need to meet one of condition A or B: A, when Direction_Target_Other_Cell-Direction_Target_Cell>0

Meet (Direction_Target_Best+MIN_ANGLE_SECTOR) < Direction_Target_Other_Cell

Target cell azimuth is then only had to need to adjust to Direction_Target_Best

Direction_Target_Other_Cell be Target cell with longitude and latitude with frequency range sector azimuth angle

Otherwise, be unsatisfactory for the same longitude and latitude sector of condition with frequency range be also required to be adjusted to

Direction_Target_Other_New=MOD ((Direction_Target_Best+360+MIN_ANGLE_ SECTOR), 360)

Direction_Target_Other_New need to adjust new azimuth for being unsatisfactory for condition with frequency range sector

B, as Direction_Target_Other_Cell-Direction_Target_Cell < 0

Meet (Direction_Target_Best+MIN_ANGLE_SECTOR)

<Direction_Target_Other_Cell+360

Target cell azimuth is then only had to need to adjust to Direction_Target_Best

Otherwise, be unsatisfactory for the same longitude and latitude of condition with frequency range sector be also required to be adjusted to

Direction_Target_Other_New=MOD ((Direction_Target_Best+360+MIN_ANGLE_ SECTOR), 360)

If 2. (< 0, then target is little for 180/ π * (Direction_Target_Best-Direction_Target_Cell) for sin District is to adjust counterclockwise

Now to Target cell with longitude and latitude with other sectors of frequency range, all need to meet one of condition C or D: C, when Direction_Target_Other_Cell-Direction_Target_Cell<0

Meet (Direction_Target_Best-MIN_ANGLE_SECTOR) Direction_Target_Other_Cell

Target cell azimuth is then only had to need to adjust to Direction_Target_Best

Otherwise, be unsatisfactory for the same longitude and latitude of condition with frequency range sector be also required to be adjusted to

Direction_Target_Other_New=MOD ((Direction_Target_Best+360-MIN_ANGLE_ SECTOR), 360)

D, works as Direction_Target_Other_Cell-Direction_Target_Cell > 0

Meet MOD (Direction_Target_Best+360-MIN_ANGLE_SECTOR) > Direction_Target_ Other_Cell

Target cell azimuth is then only had to need to adjust to Direction_Target_Best

Otherwise, be unsatisfactory for the same longitude and latitude of condition with frequency range sector be also required to be adjusted to

Direction_Target_Other_New=MOD ((Direction_Target_Best+360-MIN_ANGLE_ SECTOR), 360)

Step 15: tested rotating platform EFFECTIVENESS ESTIMATION, according to tested rotating platform amplitude, estimates that each Target cell adjusts possible sharing Effect, the tested rotating platform scheme obtained, if the amplitude of adjustment is too small, it is clear that effect will not be clearly；It is thus desirable to possible Being predicted property of effect assessment；

Constant with the Object_Antenna_Priority of sector alien frequencies Target cell is 1.

To remaining each Target cell calculating adjustment amplitude:

Adjust_Angle=MIN (ABS (Direction_Target_Best-Direction_Target_Cell), ABS (Direction_Target_Best-Direction_Target_Cell+360))

Effect is set and judges threshold parameter: ADJUST_RESULT_THRESHOLD=10

Such as Target cell Adjust_Angle < ADJUST_RESULT_THRESHOLD,

Then judging " expected effects is the least ", this Target cell priority Object_Antenna_Priority is reduced 4；

Such as Target cell ADJUST_RESULT_THRESHOLD=< Adjust_Angle < 2*ADJUST_RESULT_ THRESHOLD,

Then judge " expected effects is the most notable ", this Target cell priority Object_Antenna_Priority=max (Object_Antenna_Priority+1,6)；

Such as Target cell 2*ADJUST_RESULT_THRESHOLD≤Adjust_Angle

Then judge " expected effects is notable ", this Target cell priority Object_Antenna_Priority=(Object_ Antenna_Priority-1,1)；

Step 16: tested rotating platform collision detection and coordination, after the calculating of the whole network all objects community completes, identifies and is simultaneously The Target cell of multiple object communities, carries out priority tune according to adjustment priority, the ability of equalization, EFFECTIVENESS ESTIMATION result to it Whole；

Target cell in the final output listing of tested rotating platform of output, carries out collision detection；Tested rotating platform conflict mark need to be set Will Conflict_Flag；

When there is multiple object community, to each Target cell of output in step 10, add up it defeated in whole object communities Go out the number of times Target_Cell_Count occurred in object listing；

Such as Target_Cell_Count > 1, revise the Conflict_Flag=1 of this Target cell corresponding record all the most simultaneously；

Relatively this Target cell priority Object_Antenna_Priority in its each list occurred, priority The priority of numerical value minimum keeps constant, by this Target cell Object_Antenna_Priority=max in other lists (Object_Antenna_Priority+2,6)；

As this Target cell is identical at multiple list medium priorities, then compare and these lists remove outside this Target cell, other Minimum priority MIN (Object_Antenna_Priority_n) of Target cell, keeps the priority of this numerical value maximum not Become, by this Target cell Object_Antenna_Priority=max (Object_Antenna_Priority in other lists +2,6)；

As above-mentioned minima there is also multiple identical, the telephone traffic to be equalized of object community corresponding to the most each list TRAFFIC_OUT, the priority keeping this numerical value maximum is constant, by this Target cell Object_Antenna_ in other lists Priority=max (Object_Antenna_Priority+1,6)；

Step 17: equilibrium community compare with Target cell parameter, according to preset rules to every pair equilibrium community and Target cell it Between switching, adjacent area, the parameter such as community access compare, and provide tendency and adjust suggestion；

Parameter comparable situation between each Target cell and object community in sorted lists, and carry out tendency according to preset rules Analyze；It is presently contemplated that two class parameters:

(1) adjacent area level parameter

Such as: the two-way adjacent area level parameter of HOmargin, HO priority etc；

Need unified predefined regular:

A, two-way equal (or difference is less than certain pre-determined threshold): be judged as " currently without substantially tendency, have and necessarily adjust leeway "；Excellent First level Object_ADJPar_Priority=2

B, forward big (difference is more than thresholding): be judged as " current existing substantially tendency, adjust leeway the least "；Priority Object_ADJPar_Priority=3

C, forward little (difference is more than thresholding): be judged as " currently having obvious phase countertendency, adjust leeway the biggest "；Priority Object_ADJPar_Priority=1

Above-mentioned three kinds of comparative results, and three kinds of conclusions are the most predeterminable good, user select to be combined；Some parameter i.e. is probably " forward is big, without adjusting leeway ", other parameter can also be " forward is little, without adjusting leeway "；(2) cell-level parameter

Cell-level parameter does not has directivity, itself can only analyze from community but it also may sum up similar conclusion:

A, Target cell parameter arranges height (greatly): be judged as that " Target cell absorbs traffic trend, consistent with equalization requirement, adjusts Leeway is the least " priority Object_CellPar_Priority=3；

B, Target cell parameter is arranged low (little): be judged as that " Target cell releases traffic trend, inconsistent with equalization requirement, adjusts Whole leeway is the biggest " priority Object_CellPar_Priority=1；

C, Target cell parameter arranges identical: be judged as " currently without substantially tendency, have and necessarily adjust leeway " priority Object_ CellPar_Priority=2；

Each Target cell is calculated its equalization parameter priority

Object_Parameter_Priority=Object_CellPar_Priority+Object _ ADJPar_Priority

Output: the target cell list after sorting according to equalization parameter priority Object_Parameter_Priority；Numerical value Little person sorts front；

Comparison procedure

1, " cell parameter table " and " adjacent area parameter list " statistical parameter quantity to input, is designated as " cell parameter number " and " neighbour District's number of parameters "；

2, " number of parameters is compared "=" cell parameter number "+" adjacent area number of parameters "；

3, according to above-mentioned predefined rule, performing to compare to each parameter respectively, according to " Rule of judgment " result, output is corresponding " Object_CELLPar_Priority ", and recorded " parameter compares detailed results " and " parameter compares conclusion table " respectively Respective column；

Each Target cell is calculated its " equalization parameter priority ": Object_Parameter

_ Priority=(Object_CellPar_Priority+Object_ADJPar_Priority)/compare number of parameters

And recorded the respective column of " parameter compares conclusion table "；

4, according to the Object_Parameter_Priority numerical value calculated, generating conclusion, rule is as follows: Object_ Parameter_Priority >=2.5, conclusion is that " Target cell absorbs traffic trend, consistent with equalization requirement, adjusts leeway The least "；

2.5 > Object_ADJPar_Priority >=1.5, conclusion is " currently without substantially tendency, have and necessarily adjust leeway "

1.5 > Object_ADJPar_Priority, conclusion be " Target cell release traffic trend, inconsistent with equalization requirement, Adjust leeway the biggest "；And conclusion be recorded " conclusion " row of " parameter compares conclusion table "；

5, such as Object_Parameter_Priority >=2.5, then this Target cell is met with object cell combination Field name corresponding to Object_CellPar_Priority=3, Object_ADJPar_Priority=3 (RXP, PMRG；；；) read, after being merged into character string, recorded in " suggestion the adjusts parameter " field in " parameter compares conclusion table "；

Step 18: collect output equalization scheme, according to tested rotating platform, configuration adjustment, parameter adjustment proposed projects, collects output whole Body equalization scheme；According to above steps result of calculation, respectively the adjacent adjacent area, all geographical position of each object community is entered Row entirety sequence, generates integrated ordered list；And according to being output as overall equalization scheme suggestion after prioritization.
