Specific embodiment
Below in conjunction with attached drawing, embodiments of the present invention is described in detail.
With the introducing of active antenna system (Active Antenna System, AAS), we can be in vertical direction
One antenna dimension of upper increase.AAS, can be by each vertical antenna element point under conditions of existing antenna size is not changed
Multiple a period of time are cut into, so as to develop multiple-input and multiple-output (Multiple Input Multiple Output, MIMO) technology
In the Spatial Dimension of vertical direction.Using this dimension of vertical direction, vertical beam figuration, vertical sector division etc. can be realized
New technology.The introducing of AAS is but also the adjustment of base station (eNodeB) Downtilt becomes very flexibly, and Downtilt can
To influence the coverage area of the eNodeB.It therefore, can be by being adaptively adjusted eNodeB Downtilt, flexibly and easily
Load balancing between realization sector.Based on the load distribution of each sector, radio resource is carried out by combining between multiple sectors
Adaptive scheduling, so as to ensure high load sector do not occur.
Based on above-mentioned purpose, as shown in Figure 1, an embodiment of the present invention provides a kind of method of load balancing between sector, it should
Method includes the following steps：
S101：The load value of acquisition source sector；
It should be noted that for load balancing apparatus as executive agent, which can be between sector for the embodiment of the present invention
Each eNodeB establishes connection, adjusts the angle of declination of the antenna of each eNodeB.Wherein, source sector refers to load it
Share the sector of operation.As shown in Fig. 2, a kind of application scenarios for the embodiment of the present invention, a cell is divided into three sectors,
One cell eNodeB can be equivalent to three sector eNodeB, the number of the digital representation sector in figure in sector.Such as Fig. 2
It is shown, carry out load balancing if necessary to the sector to number 2, then the sector of number 2 is source sector, obtains number 2
The load value of sector.
S102：When the load value of the source sector is more than the first load-threshold, all the first of the source sector is obtained
The load value of cooperation sector；
The load-threshold specifically, the first load-threshold is attached most importance to, when the load value for the source sector that step S101 is obtained is more than weight
During load-threshold, represent that source sector beyond load, needs to carry out load balancing to it, at this point it is possible to obtain all of source sector
The load value of cooperation sector.Opposite, if the load value of source sector is not greater than heavy duty thresholding, represent that source sector is not super
It carries, then source sector need not carry out load balancing operation.It should be noted that for the sector of source, cooperation set of sectors is it
Antenna level (LOS) angular range within neighboring community sector, such as in Fig. 2 sector 0 cooperation set of sectors for 10,13,
14,17 }, the cooperation set of sectors of sector 10 is { 0,2,6,14 }；When source sector is sector 0, the first cooperation sector is sector
10th, sector 13, sector 14 and sector 17, and then the load value of all first cooperation sectors of source sector can be obtained.
S103：If the load value of all first cooperation sectors is respectively less than the second load-threshold, increase the source fan
The angle of declination of the antenna for base station in area reduces the angle of declination of the antenna for base station of all first cooperations sectors, to realize between sector
Load balancing；Wherein, first load-threshold is more than second load-threshold.
Specifically, the second load-threshold is light load-threshold, if all first cooperation sectors that step S102 is obtained is negative
Load value is respectively less than light load-threshold, then it represents that and the load value of all first cooperation sectors of source sector is smaller, thus, source sector
It is all first cooperation sectors can be used as share sector.Wherein, it shares sector and refers to the sector that participation source sector load is shared.
It shares the collection that sector forms and is combined into and share set of sectors.And then can it be subtracted by the angle of declination for the antenna for base station for increasing source sector
The coverage area of small source sector base stations antenna reduces the angle of declination of the antenna for base station of all first cooperation sectors, that is, increases first
The angle of declination of the antenna for base station of cooperation sector, realizes load balancing between sector.Wherein, the angle of angle of declination is increased or reduced every time
It can be 1 °.After the angle of declination of antenna for base station is changed every time, can repeat the above steps S1-S3 again, be fanned until realizing
Section load balancing.
As shown in figure 3, the eNodeB schematic diagrames to be equipped with AAS.Compared with the traditional eNodeB for being not equipped with AAS originally,
Both there are three the aerial array 31 of direction, so as to which a cell is divided into three sectors, so as to a cell
ENodeB can be equivalent to three sector eNodeB.Unlike the one-dimensional aerial array 33 of traditional eNodeB, it is equipped with AAS
The aerial array 31 of eNodeB be two-dimentional, as shown in figure 3, an aerial array is made of 4 row, 8 array antenna unit 32.One
A traditional antenna port is equivalent to a corresponding array antenna unit 32 here, and for AAS, each antenna element 32 can
To regard an antenna port as, so as to by different antenna elements 32 being configured different amplitude and phase, carry out
The adjustment of eNodeB antenna lower decline angles (Electrical Downtilt).Relative to the adjustment at mechanical tilt angle, lower decline angle
Adjustment will be flexible and convenient it is more, so as to which the method for adjusting antenna for base station angle of declination realization row load balancing for the present invention provides
Extraordinary basis.
