In the present embodiment, antenna feeder merges the information of each sector that device determines and can include that the antenna of the sector is showed The attribute information for going out, such as the information such as high, angle of declination and deflection of standing, these information can have previously been stored in the day by user Feedback merges in device.

Step 102, according to the information and preset strategy of the sector of at least two Internets determined in step 101, meter Calculate at least two Internets sector merge after the antenna feeder of new sector that obtains merge parameter.

Here the antenna feeder merging parameter of new sector is the new sector institute obtained after the sector merging by least two Internets Build-in attribute information for showing etc., the new sector can support this at least two Internet, can specifically include but not limit In following at least one：The deflection of the new sector that the sector of at least two Internets obtains after merging, high and angle of declination of standing Deng.Wherein deflection refers to that the antenna of sector is pointed to, such as antenna points to positive north, then the deflection of sector is 0 degree, and antenna is pointed to Southwest, then the deflection of sector is 120 degree；Height of standing refers to the vertical dimension of the antenna distance horizontal plane of sector；Angle of declination is referred to The horizontal plane that the antenna of sector is located and the angle of the vertical line of antenna plate face, mainly include mechanical tilt angle and electrical tilt Angle, described angle of declination refers to mechanical tilt angle and electrical tilt angle sum in the present embodiment.Antenna feeder merges device can also be counted The coverage of new sector is calculated, the coverage refers to the scope that the aerial signal of sector can be reached.

It is appreciated that user can operate antenna feeder to merge device to trigger the flow process of the present embodiment, such as user selects to need The sector of corresponding some Internets of certain to be merged website, it is respective that such antenna feeder merging device can first obtain these sectors Information, then in conjunction with preset policy calculation antenna feeder parameter is merged, wherein preset strategy can be user according to actual needs It is set in advance in antenna feeder to merge in device.What is merged if desired is the sector of two Internets, then antenna feeder merges device root Merge to form new sector according to the information of the sector of two networks, such as when the angle between the sector of two Internets（I.e. The difference of the deflection of two sectors）It is excessive such as be more than preset angle when, then take the deflection meansigma methodss conduct of two sectors Deflection of new sector etc. after merging；It is three sectors with upper network layers if necessary to what is merged, then antenna feeder merges device and exists Some antenna feeders for calculating new sector merge parameter（Such as deflection）When, the sector that can first determine two of which Internet is being closed And when the deflection of the first sector that obtains, then calculate again to merge the first sector with the sector of another Internet and obtain The second sector deflection, such cycle calculations complete until the sector of all-network layer all merges, and finally give all need The sector of the Internet to be merged merges the deflection for obtaining new sector.

Step 103, parameter is merged to the sector of at least two Internets in Internet according to the antenna feeder determined in step 102 Between merge, when the sector at least two Internets merges between Internet, mainly at least two The sector of Internet is adjusted so that the attribute information that the new sector obtained after merging is shown is that above-mentioned antenna feeder merges ginseng Number；And can't merge between the multiple sectors in an Internet.Such as 2 sectors of Internet a correspondence, and Internet b pair 2 sectors are answered, then when the sector of the two Internets merges between Internet, mainly by a sector in Internet a Merge with a sector in Internet b, and another sector in Internet a and another sector in Internet b Merge.

It can be seen that, in the method for the present embodiment, antenna feeder merges device can respectively determine the corresponding sector of at least two Internets Information, then according to the information and preset strategy of the sector of at least two Internets, calculate the fan of at least two Internets The antenna feeder of the new sector that area obtains after merging merges parameter, finally merges parameter at least two Internets further according to antenna feeder Sector merge between Internet.In the method for this sample embodiment antenna feeder merge device merge as needed each The precise information of sector and preset strategy are calculated automatically from the information i.e. antenna feeder of new sector after merging and merge parameter, compare existing Having in technology according to artificial experience merge completing antenna feeder, can reduce the difficulty of antenna feeder merging, and can ensure to merge as far as possible The performance of the new sector for obtaining afterwards.

With reference to shown in Fig. 2, in a specific embodiment, in order that shadow of the antenna feeder merging process to each Internet Ring minimum, antenna feeder merges device and also needed to perform following steps 104 and 105 before above-mentioned steps 103 are performed, specifically：

Step 104, obtains respectively the precedence information of at least two Internets, and precedence information here can be by user Arrange, the priority level communicated in Internet can be represented.

Step 105, the sector for determining the sector of at least two Internets merges mode, and the sector merges mode and includes preferentially The sector of the relatively low Internet of level enters the mode of horizontal deflection to the sector of the higher Internet of priority, so preferentially ensure that excellent The performance of sector in the higher Internet of first level.Wherein, the angle deflected when a sector deflects can be according to above-mentioned steps 102 In the deflection of new sector that obtains determining so that angle is the deflection of new sector after deflection.And merge mode in sector In can also include that the sector of two Internets deflects certain angle to other side sector respectively.

In the present embodiment, antenna feeder merges device when above-mentioned steps 103 are performed, specifically can be with according to sector merging mode And antenna feeder merges parameter and the sector of at least two Internets is merged between Internet, specifically, merges according to sector Mode adjusts the sector of at least two Internets so that the attribute information that the new sector obtained after merging is showed is antenna feeder merging Parameter.

It should be noted that do not have absolute ordering relation between above-mentioned steps 101 and 102, with step 103 and 104, Can perform simultaneously, it is also possible to which order is performed, the simply one of which concrete implementation mode shown in Fig. 2.

It is appreciated that antenna feeder merge device specifically execution step it is above-mentioned 105 when, the following two kinds situation can be divided into and come real It is existing：

（1）With reference to shown in Fig. 3, when the quantity of the sector of each Internet is identical at least two Internets, antenna feeder merges Device can realize step 105 in accordance with the following steps：

A1：Internet is ranked up according to prior information level, wherein the highest priority of first network layer, at least two Other Internets in Internet in addition to first network layer（That is the second Internet）Priority it is relatively low.If two networks The priority level of layer is identical, then can select before any one Internet comes.

A2：Determine various deflection ways that the sector of the second Internet deflects to the sector of first network layer.Here many Plant deflection way and refer to that the sector of the second Internet enters the multiple combination mode of horizontal deflection to the sector of first network layer.Wherein One Internet and the second Internet are not offered as ordering relation, but in order to illustrate different Internets.

A3：The minimum deflection way of deflection angle is selected to merge mode as sector in various deflection ways.

For example shown in Fig. 4, under UMTS network layer corresponding sector be U1, U2 and U3, the corresponding fan under GSM network layer Area is G1, G2 and G3, and the priority of GSM network layer is higher, then need the sector under UMTS network layer under GSM network layer Sector enter horizontal deflection, and deflection way can have various, such as a kind of deflection way is that sector U1 is deflected to sector G1, sector U2 to sector G2 is deflected, and sector U3 to sector G3 is deflected, be designated as [（U1→G1）,（U2→G2）,（U3→G3）], in this deflection Deflection angle under mode for the deflection of the angular G1 in direction of U1 deflection angle, and the deflection of the angular G2 in direction of U2 Deflection angle, and the deflection angle sum of the deflection of the angular G3 in direction of U3；Another kind of deflection way for [（U2→G1）,（U3 →G2）,（U1→G3）] etc..

In order that during sector deflects, the impact of the sector for merging to needs is little, can set as far as possible Under any one deflection way, the relative ranks of the sector under same Internet are constant, such as in any deflection way Under, the order of sector is the clock-wise order of U1-U2-U3 under GSM network layer, and the order of sector is G1- under UMTS network layer The clock-wise order of G2-G3.And if it should be noted that deflection angle under various deflection ways is identical and minimum, Can be to select any of which deflection way to merge mode as sector.

（2）With reference to shown in Fig. 5, when the number of sectors at least two Internets between Internet is different, antenna feeder merges dress Putting can realize step 105 in accordance with the following steps：

B1：Determine that on the basis of the sector of the Internet of sector minimum number sector at least two Internets, then at least two The sector of other Internets is non-referenced sector in individual Internet.

B2：Select minimum with the angle of reference sector in non-referenced sector, and quantity and the non-base of reference sector identical Quasi- sector.

B3：The priority Internet whether corresponding than non-referenced sector of the corresponding Internet in judgment standard sector it is preferential Level is high, if it is, execution step B4, if it is not, then execution step B5.

B4：Determine that sector merges the reference sector that mode is that the non-base station section selected in step B2 determines in step B1 Enter horizontal deflection.

B5：Determine that sector merges the non-base station section that mode is that the reference sector determined in step B1 selects in step B2 Enter horizontal deflection.

There are 2 sectors such as in GSM network layer, there are 3 sectors in UMTS network layer, then GSM network layer is right Sector on the basis of the sector answered, and the corresponding sector of UMTS network layer is non-referenced sector, when above-mentioned steps B2 are performed, can be with 2 sectors in GSM network layer are calculated respectively（GSM_Sector0、GSM_Sector1）With 3 sectors in UMTS network layer （UMTS_Sector0、UMTS_Sector1、UMTS_Sector2）Between angle, 3 sectors that can be in a umts network It is middle to select 2 sectors minimum with 2 sector angles of GSM network layer.

Specifically, if the angle of sector GSM_Sector0 and sector UMTS_Sector1 is minimum, can first according to upper Deflection way that step B3 to B5 determined between the two sectors is stated to carry out sector merging；Then sector GSM_ is being judged respectively Sector1 and sector UMTS_Sector0, and the corner dimension of sector GSM_Sector1 and sector UMTS_Sector2, and really Deflection way between two minimum sectors of clamp angle, if corner dimension is identical, can be selected with carrying out sector merging Sector（UMTS_Sector0, UMTS_Sector2）In arbitrary sector carry out sector with sector GSM_Sector1 and merge.

In another specific embodiment, antenna feeder merges device in the calculating in performing above-mentioned steps 102, specifically may be used With including following several situations：

（1）The sector of at least two Internets obtains the calculating of the deflection of new sector after merging

If the angle at least two Internets between the sector of any two Internet is less than or equal to presetting angle （Such as 15 degree）, by an Internet at least two Internets（The higher Internet of such as priority）Sector deflection As the deflection after merging, specifically, the sector angle of two Internets be by the deflection of an Internet sector with The deflection of another Internet sector subtracts each other and obtains；And using the deflection of the sector of an Internet as the deflection after merging Represented sector merges mode：Using fan of the sector of other Internets to deflection as the Internet at new sector directions angle Area directly deflects.

If the angle at least two Internets between the sector of certain two Internet is more than presetting angle, by the two Used as the deflection after merging, the concrete sector for representing merges mode and is the deflection meansigma methodss of the sector of Internet：Will at least Horizontal deflection is all entered in the sector of two Internets, deflects on the position of calculated deflection.

（2）The sector of at least two Internets obtains the calculating of the coverage of new sector after merging, with reference to shown in Fig. 6, Antenna feeder merges the new fan that device can be realized being obtained after merging for the sector of at least two Internets according to the steps The coverage in area, specifically includes：

C1：The zero layer adjacent base station set of the sector place base station of at least two Internets is determined, in zero layer adjacent base station and institute State at least two Internets sector in presetting range between the base stations without other base stations.Here zero layer can be limited adjacent Base station be with the sector of at least two Internets between the base stations distance be base station within preset distance；It is determined that zero layer is adjacent During collection of base stations, the sector place base station of arbitrary base station that specifically can be within above-mentioned preset distance and at least two Internets Between set up an ellipse, its major axis is the line between two base stations, and short axle is n times of major axis, and n is the positive number less than 1, if Other base stations are not disposed in the ellipse, the base station in preset distance then belongs to zero layer adjacent base station.Wherein the ellipse is then For above-mentioned presetting range.

It should be noted that the situation that zero layer adjacent base station is non-indoor station can be only considered in the present embodiment, and without examining Consider the situation at indoor station.

C2：The zero layer adjacent base station of the first preset strategy is not met in the zero layer adjacent base station set that step C1 is obtained to be carried out Exclude first, wherein the first preset strategy can include：The sector place base station of at least two Internets is to zero layer adjacent base station Vector, obtain the angle between the deflection of new sector after merging with the sector of at least two Internets（It is designated as α）It is less than Preset angle, here preset angle can be at least two Internets sector merge after the level half of new sector that obtains Power angle.Wherein horizontal half-power angle is antenna build-in attribute, refers to the beam angle of sector respective antenna horizontal plane, also It is the region penetrated within the power reduction 3dB of direction than master on antenna horizontal plane, the angle of horizontal half-power angle is bigger, hands in sector Covering at boundary is better, but when antenna tilt is improved, is also more susceptible to wave beam distortion, forms area covered；The work(of level half The angle at rate angle is less, and in sector, intersection covers poorer, and improving antenna tilt can improve sector boundary in mobile degree The covering at place, it is relative not allow to be also easy to produce the area covered to other cells, in downtown base station because stop spacing is little, antenna tilt Greatly, typically using the antenna that horizontal half-power angle is little, suburb is from the big antenna of horizontal half-power angle.

For example shown in Fig. 7 a, it is assumed that the new sector that the sector of at least two Internets obtains after merging is A, and one A cell in zero layer adjacent base station is B, then above-mentioned angle α=Abs（Direction after the sector merging of at least two Internets Angle-ABTONorth）, wherein ABTONorth is the vectorial D of the sector place base station of at least two Internets to zero layer adjacent base station With the angle of positive north orientation.Wherein, if the angle α is more than 180 degree, need to deduct the angle α with 360, folder is then determined again Whether angle α is less than preset angle, if it is greater, then the zero layer adjacent base station is excluded from zero layer adjacent base station set.
