S205, controller are according to the distance between multiple first adjacent area and this community, and the second adjacent area is relative to the direction of other the first adjacent areas, judge whether there is middle adjacent area in other first adjacent areas.

Wherein, middle adjacent area is for exist overlapping covered with the second adjacent area, and the distance between Qie Yuzhe community is less than the first adjacent area of the distance between the second adjacent area and this community.

Optionally, in above-mentioned S205, controller can by following method, and according to the distance between multiple first adjacent area and this community, and the second adjacent area is relative to the direction of other the first adjacent areas, judges whether there is middle adjacent area in other first adjacent areas:

If at least one first adjacent area in other first adjacent areas meets first condition, then controller determines to there is middle adjacent area in other first adjacent areas; If each first adjacent area in other first adjacent areas does not all meet first condition, then controller determines there is not middle adjacent area in other first adjacent areas.

Wherein, first condition can comprise: the distance between at least one the first adjacent area and this community is less than the distance between the second adjacent area and this community, and the second adjacent area is less than or equal to the half of the half-power angle of this at least one the first adjacent area relative to the direction of at least one the first adjacent area.

In embodiments of the present invention, by judging whether there is the first adjacent area meeting first condition in other first adjacent areas, can judge whether there is middle adjacent area in other first adjacent areas.And the first adjacent area meeting first condition in other first adjacent areas is middle adjacent area.

In order to clearly state the method judging whether to there is middle adjacent area in other first adjacent areas, below in conjunction with Fig. 3, describe the method in detail.

Exemplary, as shown in Figure 3, by above-mentioned S201-S204, can determine that the second adjacent area is the second adjacent area D in figure 3, other first adjacent areas are the first adjacent area I, and the second adjacent area D is ∠ DIK relative to the direction of the first adjacent area I, the distance between the first adjacent area I and this community O is OI, and the distance between the second adjacent area D and this community O is OD.

Controller is OI and the distance between the second adjacent area D and this community O by the distance between contrast first adjacent area I and this community O is OD, and is that the half of half-power angle of ∠ DIK and the first adjacent area I (can be expressed as Δ relative to the direction of the first adjacent area I by contrast second adjacent area D ₂), can obtain as drawn a conclusion:

Distance between first adjacent area I and this community O is the OI distance be less than between the second adjacent area D and this community O is OD, can be expressed as OI < OD.

Second adjacent area D is the half that ∠ DIK is less than or equal to the half-power angle of the first adjacent area I relative to the direction of the first adjacent area I, can be expressed as ∠ DIK≤Δ ₂.

Therefore, the first adjacent area I meets above-mentioned first condition, then controller determines to there is middle adjacent area in other first adjacent areas, and the first adjacent area I is middle adjacent area.

If adjacent area in the middle of existing in other first adjacent areas of S206, then controller determines that this community exists area covered phenomenon.

Exemplary, as shown in Figure 3, by above-mentioned S201-S205, can determine in figure 3, adjacent area in the middle of existing in other first adjacent areas, and this middle adjacent area is middle adjacent area I.Illustrate that this community O crosses middle adjacent area I and the second adjacent area D and exists overlapping covered (Ji Zhe community O area covered second adjacent area D), then controller determines that this community O exists area covered phenomenon.

Optionally, after above-mentioned S206, as shown in Figure 5, the method can also comprise:

The switching times that S207, controller switch to the second adjacent area request according to this community and the switching times that this community switches to the request of middle adjacent area, calculate first switching proportion of this community to the second adjacent area request switching.

If S208 first switching proportion is more than or equal to default ratio threshold value, then controller determines that the second adjacent area is the area covered direction of this community relative to the direction of this community.

In the embodiment of the present invention, the switching times that this community switches to the second adjacent area request and the switching times that this community switches to the request of middle adjacent area, can add up for controller, also can for base station add up after send to controller.After controller gets the switching times that switching times that this community switches to the second adjacent area request and this community switch to the request of middle adjacent area, the switching times that controller can switch to the request of middle adjacent area with this community to the switching times that the second adjacent area request switches according to this community, calculates the first switching proportion (can be expressed as η) that this community switches to the second adjacent area request.

Wherein, above-mentioned first switching proportion is for characterizing the degree of this community area covered second adjacent area.

Further, when the first switching proportion is more than or equal to default ratio threshold value, then determine that the second adjacent area is the area covered direction of this community relative to the direction of this community.

Concrete, when the first switching proportion is more than or equal to default ratio threshold value, illustrate that the degree of this community area covered second adjacent area is comparatively serious, the negative effect that area covered second adjacent area, Ji Zhe community is caused is comparatively serious, therefore needs investigate and solve.Then controller determines that the second adjacent area is the area covered direction of this community relative to the direction of this community, for the area covered direction of network engineers according to this community, the covering resource of this community of reasonable disposition, effectively to reduce the negative effect of this community area covered.Thus after avoiding in prior art and detecting community area covered, accurately can not locate the problem in the area covered direction of this community.

For example, suppose that the switching times that this community switches to the second adjacent area request is α, the switching times that this community switches to the request of middle adjacent area is β, then above-mentioned first switching proportion η=α/β.

Suppose, the ratio threshold value preset is η _thresholdingif, η>=η _thresholding, then determine that the second adjacent area is the area covered direction of this community relative to the direction of this community.

Further, provide in the embodiment of the present invention in the method for detected cells area covered, in each adjacent area of this community, first select to there are overlapping covered multiple first adjacent areas with this community.Then successively using each first adjacent area in multiple first adjacent area as the second adjacent area, whether this second adjacent area of area covered, this community is judged.Therefore, in multiple first adjacent areas of this community, may exist multiple by the second adjacent area of this community area covered.

If η determined by controller ₁>=η _thresholding, η ₂>=η _thresholding, then controller judges η further ₁with η ₂size, suppose that controller judges η>=η _thresholding, then η determined by controller ₁for η ₁and η ₂in maximum.

Further, controller is determined and η ₁the second corresponding adjacent area 1 is the area covered direction of this community relative to the direction of this community.

It should be noted that, if η determined by controller ₁>=η _thresholding, η ₂>=η _thresholding, then illustrate that the degree of this community area covered second adjacent area 1 is all relatively more serious with the degree of this community area covered second adjacent area 2, the negative effect that Ji Zhe community area covered causes is comparatively serious, therefore needs investigate and solve.Further, in order to enable the covering resource of this community of network engineers' reasonable disposition, effectively to reduce the negative effect of this community area covered, controller need determine the area covered direction of this community.If η determined by controller ₁for η ₁and η ₂in maximum, then controller can be determined and η ₁the second corresponding adjacent area 1 is the area covered direction of this community relative to the direction of this community.

S208a1, controller calculate the mean value of multiple first switching proportion.

If this mean value of S208a2 is more than or equal to ratio threshold value, then the maximum in multiple first switching proportion determined by controller.

Concrete, when controller defines the second adjacent area of p (p>=2) Ge Beizhe community area covered, then according to above-mentioned S207, the p calculated first switching proportion is respectively: this community asks the first switching proportion switched to be η to the second adjacent area 1 ₁, this community asks the first switching proportion switched to be η to the second adjacent area 2 ₂..., this community asks the first switching proportion switched to be η to the second adjacent area p _p.

Controller calculates η ₁, η ₂..., η _pmean value η _{mean value}if controller judges η _{mean value}>=η _thresholding, then controller is from η ₁, η ₂..., η _pin determine maximum.Suppose that this maximum that controller is determined is η ₁, then controller is determined and η ₁the second corresponding adjacent area 1 is the area covered direction of this community relative to the direction of this community.

Wherein, η _{mean value}the average degree of this community area covered can be characterized, work as η _{mean value}>=η _thresholdingtime, illustrate that the average degree of this community area covered is comparatively serious, the negative effect that Ji Zhe community area covered causes is comparatively serious, therefore needs investigate and solve.If η determined by controller ₁for η ₁, η ₂..., η _pin maximum, then controller is determined and η ₁the second corresponding adjacent area 1 is the area covered direction of this community relative to the direction of this community, and for the area covered direction of network engineers according to this community, the covering resource of this community of reasonable disposition, effectively to reduce the negative effect of this community area covered.
