Carry out the cost of adjacent section planning, improve planning speed.
Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.
As it is shown in figure 1, the method that the embodiment of the present invention determines adjacent area comprises the following steps:
Step 101, for one planning community, according to the aerial angle of each Target cell, from all mesh
Mark community determines the candidate adjacent of this planning community；
Step 102, determine the covering subregion of this planning community belonging to each candidate adjacent；
Step 103, according to the base station number covered in subregion between candidate adjacent and planning community, to this
The candidate adjacent of planning community is updated processing；
Step 104, this planning community after renewal processes candidate adjacent determine the neighbour of this planning community
District.
It is preferred that in step 101, according to the aerial angle of each Target cell, determine each Target cell
The first angle, wherein the first angle be for judge Target cell whether be positioned at planning MPS process direction
Angle；
If the first angle of Target cell is not more than set angle, it is determined that this Target cell is this planning community
Candidate adjacent.
It is preferred that the first angle is Target cell and line and the Target cell antenna normal direction of planning community
Angle.
As illustrated in fig. 2, it is assumed that planning community is Cell B, Target cell is Cell A, then D is Cell B
Line with Cell A；E is Cell A antenna normal；MaxD is the maximum distance that Cell B covers；Angle
Degree a is set angle；The line of angle c Cell A and Cell B and the antenna normal angular separation of Cell A.
Wherein, set angle can be set as required.It is preferred that determine also according to following equation and set
Determine angle:
Set angle=Target cell antenna beamwidth × (1+ proportionality coefficient).
Target cell antenna beamwidth determines according to antenna type, and the beam angle of such as certain antenna type is
