For the embodiment of the present invention being set forth clearly clear, provide the better embodiment of the embodiment of the present invention below.
This better embodiment provides a kind of antenna for base station deflection adjustment algorithm and the system of improving the network coverage, below provides principle and illustrates:
The cell measurement reporting statistics that the network introducing magnanimity gathers automatically, simultaneously based on the real MPS process of minizone measure analog, the real antenna calculated covers channel strength.Utilize minizone measurement report, analyze the covering relation that to become more meticulous between community pair, change the impact of analysis main plot covering on peripheral cell into from analyzing single MPS process, prediction on this basis realizes the Adjusted Option of the antenna for base station deflection of optimum covering, improves the network coverage.Cover analog result positioning antenna performance issue or antenna directional angle data problem according to antenna in cell simultaneously, mend according to antenna directional angle adjustment result location the newly-built base station demand point covered.The application of this better embodiment makes antenna cover positioning problems more accurate, antenna directional angle is adjusted more reasonable, better deals with problems and customer complaint, and at utmost excavate network potential, save networking investment.Rely on the system tool of this better embodiment, engineers and technicians can carry out antenna cover analysis on a large scale and formulate deflection Adjusted Option on backstage simultaneously, can time of conservation techniques personnel 80%, significantly increase work efficiency.
With reference to Fig. 3, algorithm and overall system comprise the steps:
Step 301: minizone metrical information gathers;
Step 302: deflection initialization and antenna cover simulation;
Step 303: improve the deflection adjustment demand estimation covered;
Step 304: search condition adjacent area;
Step 305: antenna directional angle regulating calculation;
Step 306: antenna problem and new site demand point are analyzed.
Corresponding to step 301 ~ 302, this better embodiment proposes to analyze minizone coverage condition based on metrical information, particularly:
NCS metrical information is used to analyze minizone coverage condition, by definition absolute signal strengths thresholding, measure the information such as frequency, measurement duration, community can compile the measurement report that mobile phone reports automatically, obtain the initial data of certain format, mainly comprise: measure frequency and appear at the number of times (TIMESABSS) etc. that measurement report sum (REPARFCN), the neighboring area signal intensity collected in the time measured in BA-LIST were better than or equaled absolute signal strengths thresholding.
Can by the covering relation between following two indices reflection Serving cell (S) and adjacent cell (N):
ABSS s-nthe sampled point ratio of certain absolute level value that to be cell receiver to the level value of adjacent area be greater than, computing formula is:
ABSS s - n = TIMESABSS n REPARFCN n
ABSS n-sbe the sampled point ratio that level value that adjacent area receives Serving cell is greater than certain absolute level value, computing formula is:
ABSS n - s = TIMESABSS s REPARFCN s
Wherein, ABSS s-n>=sets thresholding and ABSS n-s>=sets thresholding, represents that between S-N, region overlay is good; ABSS s-n< sets thresholding and ABSS n-s< sets thresholding, represents that between S-N, region exists covering cavity; ABSS s-n>=sets thresholding and ABSS n-s< sets thresholding, represents that between S-N, the covering of adjacent area, region is better than Serving cell; ABSS s-n< sets thresholding and ABSS n-s>=sets thresholding, represents that between S-N, regional service MPS process is better than adjacent cell.
Corresponding to step 302, this better embodiment proposes by changes in coordinates, is initially made zero by the deflection analyzing community:
Namely adjust post analysis community and be positioned at reference axis center, coverage direction is X-direction, in the coordinate-system be then scattered after the conversion in adjacent area.The half-power angle of combine antenna, main lobe coverage, setting antenna main lobe effective coverage range is ∠ C.Coordinate-system can refer to shown in Fig. 4, and in Fig. 4, angular marking is that namely the covering of the fan of ∠ C can be considered antenna main lobe effective coverage range.Based on above-mentioned to ABSS n-sdefinition and computing formula, can ABSS be utilized n-scarry out the signal strength signal intensity of calculation services community within the scope of adjacent area, so analog service MPS process, ABSS n-s>=sets thresholding and represents that community covers well on this direction, adjacent area, ABSS n-s< sets thresholding and represents that community covers deficiency on this direction, adjacent area.
Corresponding to step 303, this better embodiment proposes to calculate the available region covered by the improvement of adjustment antenna in cell deflection:
Calculate s-n and cover hole region, i.e. ABSS s-n< sets thresholding and ABSS n-s< sets the s-n community pair of thresholding, and is positioned at which quadrant of coordinate-system according to this kind of adjacent area antenna of community calculation of longitude & latitude.If adjacent area n is positioned at second or three quadrants, illustrates that covering cavity between s-n does not design in coverage at Serving cell s, do not need adjustment s deflection.If n is positioned at first or fourth quadrant, adjustment s deflection may be needed.If antenna be positioned at first or the adjacent cell of fourth quadrant be n2, if n2 is positioned at fourth quadrant, and s-n2 region memory is in covering cavity, so can consider that the antenna directional angle adjusting s is clockwise to cover this region; Otherwise if n2 antenna is positioned at first quartile, and s-n2 region memory is in covering cavity, then can adjust the antenna directional angle of s counterclockwise to cover this region.In Fig. 4, n2 is positioned at fourth quadrant.
Corresponding to step 303, this better embodiment also proposes to judge that s-n covers hole region whether in the effective overlay area of antenna, particularly:
Calculate the angle ∠ F of s-n2 aerial position line and abscissa, if so can think that this covering hole region is within s effective coverage range, so the antenna directional angle of s is without the need to adjustment.
Corresponding to step 304, this better embodiment proposes to search for the adjacent area satisfied condition, particularly:
Suppose to there is adjacent area n1, and meet following four conditions:
Condition one: ABSS n1-s>=thresholding;
Condition two: n1 community is only positioned at quadrant one or quadrant four;
Condition three: n1 community is positioned at the another one quadrant being different from n2 community;
The angle ∠ E of condition four: s-n1 position line and abscissa meets: | ∠ E| all satisfy condition one to three adjacent area in maximum.
Corresponding to step 305, this better embodiment is given chapter and verse condition adjacent area, carries out antenna directional angle Adjustable calculation, particularly:
If so s community is described once regulate antenna directional angle to there will be the situation of attending to one thing and lose sight of another, now regulates antenna directional angle without the need to s community.Otherwise, can think that certain direction outside theoretical coverage, s community can also provide effective covering to a certain degree, namely may be that this space attenuation is less, so can consider to regulate deflection to go to strengthen weak overlay area, consider the distance factor of s-n1, namely ensure the covering in 1.5 times of desirable coverage distances, deflection regulating calculation formula is:
&Delta; &angle; D = ( &angle; E - 1 2 &angle; C ) L s - n 1 &theta; * L desire if &angle; E > 0 ( &angle; E + 1 2 &angle; C ) L s - n 1 &theta; * L desire if &angle; E < 0
Corresponding to step 304, this better embodiment proposes positioning antenna problem and newly-built station demand point, particularly:
Analog result positioning antenna performance issue or antenna directional angle data problem is covered according to antenna in cell, namely n1 satisfies condition one and community is positioned at second or third quadrant, illustrate s antenna in cell secondary lobe or back lobe gain excessive, need to check antenna performance, or s antenna in cell deflection error in data is described.
The newly-built base station demand point covered is mended in antenna directional angle adjustment analysis result location according to s and n, if namely the antenna directional angle of Serving cell and adjacent cell all illustrating this covering hole region not by regulating antenna directional angle to solve without the need to regulating, needing new site to mend and covering.
By above-mentioned algorithm and system, the network coverage can be improved by antenna for base station deflection adjustment:
Utilize minizone measurement report, analyze the covering relation that to become more meticulous between community pair, change the impact of analysis main plot covering on peripheral cell into from analyzing single MPS process, prediction on this basis realizes the Adjusted Option of the antenna for base station deflection of optimum covering, improves the network coverage.Based on application of the present invention, make antenna cover positioning problems more accurate, antenna directional angle is adjusted more reasonable, better deal with problems and customer complaint, at utmost excavate network potential, save networking investment.Rely on system tool of the present invention, engineers and technicians can carry out antenna cover analysis on a large scale and formulate deflection Adjusted Option on backstage simultaneously, can time of conservation techniques personnel 80%, significantly increase work efficiency.
In addition, wider owing to surveying quantitative analysis applicable surface based on minizone, the system possessing distinct device or the standard of collecting measurement report condition all can image data or carry out data transaction and carry out the adjustment of antenna for base station deflection and analyze, therefore above-mentioned algorithm and system may be used for possessing in the system of collecting measurement report condition equally.
Current technology emphasis is mainly determined current area antenna directional angle, or simulates the current covering in community, only considers the coverage condition of single subdistrict self.So the current covering in community and antenna directional angle can only be determined, and the reasonable setting that can not regulate according to the quality prediction community deflection of current covering.The simulation of current area covering simultaneously and antenna directional angle determination technology mainly rely on road test or free space propagation model, wherein there is the large and inefficient problem of workload in road test, and operate comparatively Important Relations with technical staff, conclusion accuracy is not high, free space propagation model then needs to implement to correct according to actual environment, also exists and produces the low and inaccurate problem of effect.
The present invention efficiently solves the problems referred to above:
The cell measurement reporting statistics that the network introducing magnanimity gathers automatically, reduces manual operation error;
Measure based on minizone, MPS process that is virtually reality like reality, the real antenna calculated covers channel strength, without the need to using propagation model, avoiding propagation model complexity and inaccuracy problem, obtaining result more accurate;
Utilize minizone measurement report, analyze the covering relation that to become more meticulous between community pair, change the impact of analysis main plot covering on peripheral cell into from analyzing single MPS process, prediction on this basis realizes the Adjusted Option of the antenna for base station deflection of optimum covering, improves the network coverage.Based on the antenna for base station deflection adjustment algorithm and the systematic difference that improve the network coverage, make antenna cover positioning problems more accurate, antenna directional angle is adjusted more reasonable, better deal with problems and customer complaint.Rely on system tool of the present invention, engineers and technicians can carry out antenna cover analysis on a large scale and formulate deflection Adjusted Option on backstage simultaneously, can time of conservation techniques personnel 80%, significantly increase work efficiency.
