Referring to Fig. 3, algorithm and system generally include following steps:
Step 301: the acquisition of minizone metrical information；
Step 302: deflection initialization and antenna covering simulation；
Step 303: improving the deflection adjustment demand estimation of covering；
Step 304: search condition adjacent area；
Step 305: antenna directional angle regulating calculation；
Step 306: antenna problem and new site demand point analysis.
Corresponding to step 301~302, this better embodiment proposes to analyze minizone coverage condition based on metrical information,
Specifically:
Minizone coverage condition is analyzed using NCS metrical information, by defining absolute signal strengths thresholding, measurement frequency
Information, the cells such as point, measurement duration can compile the measurement report that mobile phone reports automatically, obtain the original number of certain format
According to, specifically include that measurement frequency point appear in BA-LIST be measured time in be collected into measurement report sum
(REPARFCN), neighboring area signal intensity be better than or equal to absolute signal strengths thresholding number (TIMESABSS) etc..
It can reflect the covering relation between serving cell (S) and adjacent cell (N) by following two index:
ABSSs-nIt is sampled point ratio of the level value greater than some absolute level value that serving cell receives adjacent area, calculates
Formula are as follows:
ABSSn-sIt is sampled point ratio of the level value greater than some absolute level value that adjacent area receives serving cell, calculates
Formula are as follows:
Wherein, ABSSs-n>=setting thresholding and ABSSn-s>=setting thresholding indicates that region overlay is good between S-N；
ABSSs-n< setting thresholding and ABSSn-s< setting thresholding indicates that region has covering cavity between S-N；ABSSs-n>=setting thresholding
And ABSSn-s< setting thresholding indicates that the covering of region adjacent area is better than serving cell between S-N；ABSSs-n< setting thresholding and ABSSn-s
>=setting thresholding indicates that regional service MPS process is better than adjacent cell between S-N.
Corresponding to step 302, this better embodiment proposes initially to return the deflection for analyzing cell by changes in coordinates
Zero:
That is adjustment post analysis cell is located at coordinate axis center, and coverage direction is X-direction, and adjacent area is then scattered in transformed
In coordinate-system.The half-power angle of combine antenna, main lobe coverage area, set antenna main lobe effective coverage range as
∠C.Coordinate-system can refer to shown in Fig. 4, and the covering of the fan that angular marking is ∠ C in Fig. 4 can be considered that antenna main lobe effectively covers model
It encloses.Based on above-mentioned to ABSSn-sDefinition and calculation formula, can use ABSSn-sTo calculate serving cell within the scope of adjacent area
Signal strength, and then analog service MPS process, ABSSn-sIt is good that >=setting thresholding indicates that cell covers on the adjacent area direction
It is good, ABSSn-s< setting thresholding indicates that cell covers deficiency on the adjacent area direction.
Corresponding to step 303, this better embodiment proposes that calculating available improve by adjusting antenna in cell deflection covers
The region of lid:
Calculate s-n covering hole region, i.e. ABSSs-n< setting thresholding and ABSSn-sThe s-n cell pair of < setting thresholding,
And which quadrant of coordinate-system be located at according to this kind of adjacent area antenna of cell calculation of longitude & latitude.If adjacent area n is located at second or three
Quadrant illustrates to cover cavity not in serving cell s design coverage area between s-n, does not need adjustment s deflection.If n is located at
First or fourth quadrant may then need to adjust s deflection.If antenna is n2 positioned at the adjacent cell of first or fourth quadrant, if
N2 is located at fourth quadrant, and there is covering cavity in the region s-n2, then it is contemplated that adjusting the antenna directional angle of s clockwise
To cover the region；, whereas if n2 antenna is located at first quartile, and has covering cavity in the region s-n2, then it can be inverse
Hour hands adjust the antenna directional angle of s to cover the region.In Fig. 4, n2 is located at fourth quadrant.
Corresponding to step 303, this better embodiment also proposes judge whether s-n covering hole region is effective in antenna
In overlay area, specifically:
The angle ∠ F of s-n2 aerial position line and abscissa is calculated, ifSo it is considered that this is covered
Lid hole region is within s effective coverage range, then the antenna directional angle of s is without adjustment.
Corresponding to step 304, this better embodiment proposes that search meets the adjacent area of condition, specifically:
Assuming that there are adjacent area n1, and meet following four condition:
Condition one: ABSSn1-s>=thresholding；
Two: n1 cell of condition is only positioned at quadrant one or quadrant four；
Three: n1 cell of condition is located at another quadrant different from n2 cell；
The angle ∠ E of four: s-n1 position line of condition and abscissa meets: | ∠ E | in all conditions one to three that meet
It is maximum in adjacent area.
Corresponding to step 305, this better embodiment proposes to carry out antenna directional angle adjustment according to condition adjacent area and calculate,
Specifically:
IfSo illustrate that s cell once adjusts antenna directional angle and will appear the case where attending to one thing and lose sight of another,
Antenna directional angle is adjusted without s cell at this time.It is on the contrary, it is believed that some direction of s cell except theoretical coverage is also
A degree of effective covering can be provided, it is possible to be that the space attenuation is less, then going to increase it is contemplated that adjusting deflection
Strong and weak overlay area comprehensively considers the distance factor of s-n1, that is, guarantees the covering in 1.5 times of ideal coverage distances, deflection tune
Save calculation formula are as follows:
Corresponding to step 304, this better embodiment proposes positioning antenna problem and newly-built station demand point, specifically:
Analog result positioning antenna performance problem or antenna directional angle data problem are covered according to antenna in cell, i.e. n1 meets
Condition one and cell is located at second or third quadrant, illustrates that s antenna in cell secondary lobe or back lobe gain are excessive, needs to check antenna
Performance, or illustrate s antenna in cell deflection error in data.
The newly-built base station demand point that covering is mended in analysis result positioning is adjusted according to the antenna directional angle of s and n, i.e., if service
The antenna directional angle of cell and adjacent cell, which is all not necessarily to adjust, illustrates that the covering hole region cannot be by adjusting antenna directional angle solution
Certainly, new site is needed to mend covering.
By above-mentioned algorithm and system, the network coverage can be improved by antenna for base station deflection adjustment:
Using minizone measurement report, covering relation is refined between analysis cell pair, from the covering transformation of analysis single subdistrict
The influence to peripheral cell is covered for analysis main plot, the antenna for base station deflection of optimal covering is realized in prediction on this basis
Adjusted Option improves the network coverage.Based on application of the invention, so that the positioning of antenna covering problem is more accurate, so that antenna side
It is more reasonable to adjust to angle, preferably solves the problems, such as and customer complaint, utmostly excavates network potential, saves network construction throwing
Money.System tool of the invention is relied on simultaneously, and engineers and technicians can carry out antenna covering analyzing and system on backstage on a large scale
Determine deflection Adjusted Option, the time of technical staff 80% can be saved, greatly improve working efficiency.
Further, since the analysis applicable surface based on minizone measurement is wider, the difference for having collection measurement report condition is set
Standby or standard system can acquire data or carry out data conversion progress antenna for base station deflection adjustment analysis, therefore above-mentioned algorithm
It can be equally used for having in the system for collecting measurement report condition with system.
Technology emphasis is mainly determined current area antenna directional angle at present, or progress is currently covered to cell
Simulation only considers the coverage condition of single subdistrict itself.So can only determine that cell currently covers and antenna directional angle, and cannot
The reasonable setting adjusted according to the quality prediction cell deflection currently covered.The simulation of current area covering simultaneously and antenna direction
Angle determines that technology relies primarily on road test or free space propagation model, and wherein there are heavy workloads and low efficiency for road test
