Description
Technical field
The present invention relates to communication technical field, particularly to the method and device of a kind of Neighborhood Optimization.
Background technology
Automatic Neighboring Relation (ANR, Automatic Neighbour Relation) refers to that network side is by end
Hold the Physical Cell Identifier (PCI, Physical Cell ID) to adjacent area around and cell ID (CGI, Cell
Global Identity) measurement and reporting functions, configuration and the optimization of neighborhood region correlation chart can be automatically performed,
Comprise automatically adding and deleting of neighbor cell.One complete ANR adjacent area adds flow process such as Fig. 1 automatically
Shown in, this process is simultaneously suitable for homogeneous-frequency adjacent-domain and the interpolation of alien frequencies adjacent area.After terminal is linked into network,
Base station configures to terminal sending measuring, the thresholding as nearby region measurement and reported and foundation.Terminal to report is adjacent
After district PCI, if base station, Serving cell place finds that the community of terminal to report is that unknown adjacent area, i.e. adjacent area are closed
It is the table information that there is not this community, then terminal can be indicated to read the CGI of this community.Base station gets terminal
After the CGI reported, i.e. learn that the essential information of this community, Hui Jianggai community join neighborhood region correlation chart.
In neighborhood region correlation chart, have recorded all neighboring BS information of certain community, comprise the mark of community and corresponding neighbour
Cell relation attribute, the management of neighborhood region correlation chart is mainly realized by arranging of neighboring BS relationship attribute.3GPP
Neighboring BS relationship attribute defined in agreement has following three kinds: the first, forbid switching (No HO): if
Certain adjacent area of one community is arranged to " No HO ", then terminal can not be switched to this adjacent area from Serving cell；
The second, forbids X2 (No X2): if certain adjacent area of a community is arranged to " No X2 ", then
Would not allow for carrying out any flow process relevant with X2 between the two community, such as switched by X2 mouth,
Interactive interference and Payload message etc.；The third, deletion disabled (No Remove): if a community
Certain adjacent area is arranged to " No Remove ", the most all can not delete this adjacent area from table
Relation.
And the length of usual neighborhood region correlation chart is limited, then be likely to out in the automatic adding procedure in adjacent area
The phenomenon that existing neighborhood region correlation chart fills up and cannot add.In order to solve this problem, carry in ANR mechanism
Having gone out the function that neighborhood region correlation chart optimizes, i.e. in the case of neighborhood region correlation chart fills up, system will be according to depositing
Neighboring BS relationship handover success rate, find that the index such as number of times carries out prioritization, and be automatically deleted low excellent
The neighboring BS relationship of first level is to ensure that the adjacent area newly reported can join in neighborhood region correlation chart, thus is not expanding
The effect that neighboring BS information is complete is reached under conditions of neighborhood region correlation chart length.But existing ANR function is in reality
Finding in internet application, after this function is opened, system can add a large amount of super remote adjacent area automatically, and wherein removes
A small amount of super remote adjacent area is the normal adjacent area needing to retain, and other super remote adjacent areas are redundancy adjacent areas, the most should not
Add neighboring BS relationship.And the success rate that the interpolation of the super remote adjacent area of redundancy may cause this area terminal to switch declines,
Increase unnecessary switching, and take the negative effects such as neighborhood region correlation chart resource.
