The embodiment of the present invention provides a kind of antenna feeder merging method, it is mainly the antenna-feedback system merging for heterogeneous networks layer on a website, use multifrequency antenna to replace the situation of existing a plurality of single-band antennas, its essence is exactly the merging between the sector of heterogeneous networks layer on a website, one of them antenna represents a sector, the method of the embodiment of the present invention is that antenna feeder merges the performed method of device, and flow chart as shown in Figure 1, comprising:

Step 101, determines respectively the information of the sector that at least two network layers are corresponding.

Be appreciated that, here network layer can be universal mobile telecommunications system (Universal Mobile Telecommunications System, UMTS), global system for mobile communications (Global System for Mobile Communications, GSM) or Long Term Evolution (Long Term Evolution, the network such as LTE), each network layer comprises at least one antenna, a corresponding sector of antenna, in above-mentioned at least two network layers, each network layer can corresponding a plurality of sectors.

In the present embodiment, the information that antenna feeder merges each definite sector of device can comprise the attribute information that the antenna of this sector shows, such as information such as high, the angle of declination in station and deflections, these information can be stored in advance this antenna feeder by user and merge in device.

Step 102, according to the information of the sector of at least two network layers determining in step 101 and preset strategy, the antenna feeder of the new sector obtaining after the sector of at least two network layers of calculating merges merges parameter.

Here to merge parameter be the build-in attribute information that shows of the new sector that obtains after the sector of at least two network layers is merged etc. to the antenna feeder of new sector, this at least two network layers can be supported in this new sector, specifically can include but not limited to following at least one: the deflection of the new sector that the sector of at least two network layers obtains after merging, stand high and angle of declination etc.Wherein deflection refers to the antenna direction of sector, and such as antenna direction is just northern, the deflection of sector is 0 degree, antenna direction southwest, and the deflection of sector is 120 degree; The high vertical range that refers to the antenna distance horizontal plane of sector of standing; Angle of declination refers to the horizontal plane at antenna place of sector and the angle of the vertical line of antenna plate face, mainly comprises mechanical tilt angle and electrical tilt angle, and in the present embodiment, said angle of declination refers to mechanical tilt angle and electrical tilt angle sum.Antenna feeder merges device can also calculate the coverage of new sector, and this coverage refers to the scope that the aerial signal of sector can arrive.

Be appreciated that, user can operate antenna feeder and merge device to trigger the flow process of the present embodiment, such as user selects the sector of some network layer that certain website of need merging is corresponding, antenna feeder merging device can first obtain these sectors information separately like this, then in conjunction with preset policy calculation antenna feeder, merge parameter, wherein preset strategy can be that user sets in advance according to actual needs in antenna feeder merging device.If what need merging is the sector of two network layers, antenna feeder merges device and merges the new sector of formation according to the information of the sector of two networks, such as the angle between the sector when two network layers (the deflection of two sectors is poor) is excessive when being greater than preset angle, the deflection mean value of getting two sectors is as the deflection of new sector after merging etc.; If what need merging is the sector of three above network layers, antenna feeder merges device when some antenna feeder that calculates new sector merges parameter (such as deflection), can first determine the deflection of the first sector that wherein sector of two network layers obtains when merging, and then calculating merges the sector of the first sector and another network layer the deflection of the second sector obtaining, cycle calculations, until the sector of all-network layer has all merged, finally obtains all sectors of the network layer of merging that need and merges the deflection that obtains new sector like this.

Step 103, according to antenna feeder definite in step 102, merging parameter merges between network layer the sector of at least two network layers, when the sector of at least two network layers is merged between network layer, be mainly that the sector of at least two network layers is adjusted, the attribute information that the new sector that makes to obtain after merging shows is that above-mentioned antenna feeder merges parameter; And can't merge between a plurality of sectors in a network layer.Such as corresponding 2 sectors of network layer a, and corresponding 2 sectors of network layer b, when the sector of these two network layers merges between network layer, be mainly that a sector in sector in network layer a and network layer b is merged, and another sector in network layer a and another sector in network layer b merge.

Visible, in the method for the present embodiment, antenna feeder merges the information that device can be determined respectively the sector that at least two network layers are corresponding, then according to the information of the sector of at least two network layers and preset strategy, the antenna feeder of the new sector obtaining after the sector of at least two network layers of calculating merges merges parameter, finally according to antenna feeder, merges parameter again the sector of at least two network layers is merged between network layer.After the precise information of each sector that in the method for the present embodiment, antenna feeder merging device merges as required like this and preset strategy automatically calculate and merge, the information of new sector is that antenna feeder merges parameter, compared to existing technology, according to artificial experience, completing antenna feeder merges, can reduce the difficulty that antenna feeder merges, and the performance of the new sector obtaining after can as far as possible guaranteeing to merge.

Shown in figure 2, in a specific embodiment, in order to make antenna feeder merging process minimum on the impact of each network layer, antenna feeder merges device and also needed to carry out following steps 104 and 105 before carrying out above-mentioned steps 103, particularly:

Step 104, obtains respectively the precedence information of at least two network layers, and the precedence information here can be arranged by user, can represent the priority level of communicating by letter in network layer.

Step 105, the sector of determining the sector of at least two network layers merges mode, this sector merging mode comprises the mode that deflection is carried out to the sector of the higher network layer of priority in the sector of the network layer that priority is lower, the preferential like this performance that has guaranteed sector in network layer that priority is higher.Wherein, during a sector deflection, the angle of deflection can be determined according to the deflection of the new sector obtaining in above-mentioned steps 102, makes the deflection that angle is new sector after deflection.And in sector merging mode, can also comprise that the sector of two network layers is respectively to the other side sector deflection certain angle.

In the present embodiment, antenna feeder merges device when carrying out above-mentioned steps 103, specifically can merge mode and antenna feeder according to sector merges parameter the sector of at least two network layers is merged between network layer, particularly, according to sector merging mode, adjust the sector of at least two network layers, the attribute information that the new sector that makes to obtain after merging shows is that antenna feeder merges parameter.

It should be noted that, above-mentioned steps 101 and 102, and do not have absolute ordinal relation between step 103 and 104 can be carried out simultaneously, also can sequentially carry out the just a kind of concrete implementation wherein shown in Fig. 2.

Be appreciated that antenna feeder merges device and specifically performing step at above-mentioned 105 o'clock, can be divided into following two kinds of situations and realize:

(1), with reference to shown in figure 3, when at least two network layers, the quantity of the sector of each network layer is identical, antenna feeder merges device can carry out performing step 105 in accordance with the following steps:

A1: according to prior information level, network layer is sorted, wherein the priority of first network layer is the highest, the priority of other network layer at least two network layers except first network layer (being second network layer) is lower.If there is the priority level of two network layers identical, can select before any network layer comes.

A2: determine that the sector of second network layer is to the multiple deflection way of the sector deflection of first network layer.The multiple deflection way here refers to that the sector of second network layer carries out the multiple combination mode of deflection to the sector of first network layer.First network layer and second network layer order of representation relation not wherein, but for different network layers is described.

A3: select the deflection way that deflection angle is minimum to merge mode as sector in multiple deflection way.

Example as shown in Figure 4, sector corresponding under UMTS network layer is U1, U2 and U3, sector corresponding under GSM network layer is G1, G2 and G3, and the priority of GSM network layer is higher, need the sector under UMTS network layer to carry out deflection to the sector under GSM network layer, and deflection way can have multiple, such as a kind of deflection way is the G1 deflection of U1Xiang sector, sector, the G2 deflection of U2Xiang sector, sector, the G3 deflection of U3Xiang sector, sector, be designated as [(U1 → G1), (U2 → G2), (U3 → G3)], deflection angle under this deflection way is that the deflection of U1 is to the deflection angle of the deflection of G1, and the deflection of U2 is to the deflection angle of the deflection of G2, and the deflection of U3 is to the deflection angle sum of the deflection of G3, another kind of deflection way is [(U2 → G1), (U3 → G2), (U1 → G3)] etc.

In order to make in the process of sector deflection, the impact of the sector as far as possible needs being merged is little, can be set under any deflection way, the relative order of the sector under same network layer is constant, for example, under any deflection way, under GSM network layer, the order of sector is the clockwise order of U1-U2-U3, and under UMTS network layer, the order of sector is the clockwise order of G1-G2-G3.And it should be noted that, if the deflection angle under multiple deflection way is identical and minimum, can select wherein any deflection way to merge mode as sector.

(2), with reference to shown in figure 5, when number of sectors at least two network layers between network layer is different, antenna feeder merges device can carry out performing step 105 in accordance with the following steps:

B1: the sector of determining the network layer of sector minimum number at least two network layers is reference sector, the Wei Fei reference sector, sector of other network layer at least two network layers.

B2: the angle of selection and reference sector is minimum in non-reference sector, and the quantity non-reference sector identical with reference sector.

B3: the priority of the network layer whether priority of the network layer that judgment standard sector is corresponding is more corresponding than non-reference sector is high, if so, performs step B4, if not, perform step B5.

B4: determine that merging mode in sector is the non-base station section selected in step B2 and carries out deflection to definite reference sector in step B1.

B5: determine that merging mode in sector is reference sector definite in step B1 and carries out deflection to the non-base station section of selecting in step B2.

Such as there are 2 sectors in GSM network layer, in UMTS network layer, there are 3 sectors, sector corresponding to GSM network layer is reference sector, and Wei Fei reference sector, sector corresponding to UMTS network layer, when carrying out above-mentioned steps B2, can calculate respectively 2 sector (GSM_Sector0 in GSM network layer, GSM_Sector1) with UMTS network layer in 3 sector (UMTS_Sector0, UMTS_Sector1, UMTS_Sector2) angle between, in can 3 sectors in UMTS network, select 2 sectors with 2 sector angle minimums of GSM network layer.

Particularly, if the angle of sector GSM_Sector0 and sector UMTS_Sector1 is minimum, can be first according to above-mentioned steps B3, to B5, determine that deflection way between these two sectors is to carry out sector merging; Then judging respectively sector GSM_Sector1 and sector UMTS_Sector0, and the corner dimension of sector GSM_Sector1 and sector UMTS_Sector2, and the deflection way between two sectors of definite angle minimum is to carry out sector merging, if corner dimension is identical, can select arbitrary sector and sector GSM_Sector1 in sector (UMTS_Sector0, UMTS_Sector2) to carry out sector merging.

In another specific embodiment, when antenna feeder merges the calculating of device in carrying out above-mentioned steps 102, specifically can comprise following several situation:

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

If the angle at least two network layers between the sector of any two network layers is less than or equal to presetting angle (such as 15 degree), by the deflection of the sector of a network layer (such as the higher network layer of priority) at least two network layers as the deflection after merging, particularly, the sector angle of two network layers is to be subtracted each other and obtained by the deflection of a network layer sector and the deflection of another network layer sector; And the represented sector merging mode of deflection using the deflection of the sector of a network layer after merging is: using the sector of other network layer to deflection as the direct deflection in sector of the network layer at new sector directions angle.

If the angle at least two network layers between the sector of certain two network layer is greater than presetting angle, deflection using the deflection mean value of the sector of these two network layers after merging, the concrete sector merging mode representing is: deflection is all carried out in the sector of at least two network layers, deflect on the position of the deflection calculating.

The sector of (2) at least two network layers obtains the calculating of the coverage of new sector after merging, shown in figure 6, antenna feeder merges the coverage that device can be realized according to following step the new sector obtaining after the sector merging at least two network layers, specifically comprises:

C1: determine the adjacent collection of base stations of zero layer of the base station, place, sector of at least two network layers, there is no other base station in the presetting range between the zero adjacent base station of layer and the base station, place, sector of described at least two network layers.Here can limit the zero adjacent base station of layer and be and the base station, place, sector of at least two network layers between distance be the base station within preset distance; When determining the adjacent collection of base stations of zero layer, between arbitrary base station that specifically can be within above-mentioned preset distance and the base station, place, sector of at least two network layers, set up an ellipse, its major axis is two lines between base station, minor axis is n times of major axis, n is less than 1 positive number, if do not dispose other base station in this ellipse, this base station in preset distance belongs to the zero adjacent base station of layer.Wherein this ellipse is above-mentioned presetting range.

It should be noted that, can the adjacent base station of method considering zero layer in the present embodiment the situation that is non-indoor station, and need not consider the situation at indoor station.

C2: the zero adjacent base station of layer that does not meet the first preset strategy in the adjacent collection of base stations of zero layer that step C1 is obtained got rid of first, wherein the first preset strategy can comprise: the base station, place, sector of at least two network layers is to the vector of the zero adjacent base station of layer, and the angle (being designated as α) that the sector of at least two network layers obtains between the deflection of new sector after merging is less than preset angle, preset angle can be the horizontal half-power angle of the new sector that obtains after the sector of at least two network layers merges here.Wherein horizontal half-power angle is antenna build-in attribute, refer to the beamwidth of sector respective antenna horizontal plane, namely on antenna horizontal plane, than the main direction power of penetrating, reduce 3dB with interior region, the angle of horizontal half-power angle is larger, covering at sector intersection is better, but when improving antenna tilt, also more easily there is wave beam distortion, form area covered; The angle of horizontal half-power angle is less, it is poorer at sector intersection, to cover, improve antenna tilt and can in mobile degree, improve the covering of sector intersection, relatively be not easy to produce the area covered to other community, in city's center base station because stop spacing is little, antenna tilt is large, generally adopts the antenna that horizontal half-power angle is little, and the antenna that horizontal half-power angle is large is selected in suburb.

Wherein, D _aBfor the distance between the new sector A obtaining after the community B of selection and the merging of the sector of at least two network layers, D _aBfor the community C of selection and the distance between new sector A; The station that HB is the community B respective antenna selected is high, and the station that HC is the community C respective antenna selected is high, and the sector that HA is at least two network layers obtains the station of new sector A after merging high, and HB, HA and HC are the relative altitudes of ordering with respect to P; N and m meet the relation of following formula (2), d1=AP1 wherein, and d2=CP1:
