Specific embodiment
Purpose, technical scheme and advantage to make the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present invention
In attached drawing, the technical solution in the embodiment of the present invention is explicitly described, it is clear that described embodiment be the present invention
Part of the embodiment, instead of all the embodiments.
At present, 3GPP agreements provide the PCI codes of 504 pseudo random numbers, are that the identification of TD-LTE network cells and channel are same
The mark of step, by PSS (Primary Synchronization Signal, primary synchronization signal) and SSS (Secondary
Synchronization Signal, secondary synchronization signal) it is common determining, the PCI codes configuration such as base station in system is improper, first shadow
Loud is cell synchronous, and what is secondly generated is area interference.
For this purpose, in practical networking application, in a limited number of PCI codes configurations, necessarily occur equipped with identical PCI codes not
Same cell, in order to avoid inter-cell interference and correctly identifies each adjacent area, and the configuration of PCI codes needs to meet two following conditions：
1) do not conflict：The adjacent co-frequency cell of any two can not be used same PCI codes；
2) do not obscure：There cannot be any two co-frequency cell to use identical PCI codes in all adjacent areas of a cell.
First condition ensures that UE distinguishes different neighboring communities, because of UE (User Equipment, user equipment) nothing
Method distinguishes two neighboring communities with frequency with PCI codes.Second condition ensures that current area can correctly identify two adjacent areas, because
For UE after cell edge area is entered with regard to reporting measurement reports, measurement report is to identify different community by PCI codes, if
Current service cell possesses identical PCI codes there are two homogeneous-frequency adjacent-domain, then it is to be directed to that serving cell, which will be unable to distinguish UE measurement reports,
Which adjacent area, thus correct switch decision can not be made, UE also just can not normally switch in minizone.
Generally using centralized and distributed, centralization is unified for PCI codes self-configuration method of the prior art by OM
ENodeB issues the PCI codes of cell distribution；It is distributed first to provide a candidate PCI table by OM, it then will wherein by eNodeB
Some unsuitable PCI codes exclude, and finally randomly choose the PCI codes as oneself cell from remaining list by eNodeB.

It stands and the geographical location information of request feedback is obtained according to the geographical location.
Alternatively, the pre-stored engineering parameter table with the base station of identifier lookup of the base station can also be passed through；From the base
The geographical location information of base station is obtained in the engineering parameter table stood.The example of engineering parameter table described in following article.
102nd, check whether the geographical location of the base station belongs to a region in divided nine grids region；
If a region in the 103, belonging to divided nine grids region in step 102, choose at least three and connect
Continuous PCI codes distribute to the base station；Described three continuous PCI codes are corresponding for the geographical location affiliated area of the base station
The unallocated PCI codes used in PCI code characters.
Optionally, if the geographical location of the base station in abovementioned steps 102 is not belonging in divided nine grids region
One region is at this point, method shown in FIG. 1 further includes following steps 104：
104：Nine grids are divided according to the geographical location of the base station, are obtained one-to-one with the PCI code characters of nine piecemeals
Nine grids region；Wherein, the geographical location of the base station belongs to a region in the nine grids region after dividing.
105th, at least three continuous PCI codes are chosen and distributes to the base station；Wherein, described three continuous PCI codes are
The unallocated PCI codes used in the corresponding PCI code characters of geographical location affiliated area of the base station.
That is, the management station including PCI code configuration devices first checks whether the geographic area comprising this base station has drawn
Nine grids region is divided, if the center for not automatically selecting a geographic area divides nine grids region.
And then for PCI codes to be allocated base station in 9 palace lattice position, unused PCI code characters are searched, if do not found
Prompting waits for artificial treatment without available PCI code information；If find automatic distribution available PCI code.
It should be noted that in the present embodiment before step 103 is performed, the method further includes not to be shown in following figures
The step 103a gone out：
103a：Whether check has unallocated use in the corresponding PCI code characters of geographical location affiliated area of the base station
PCI codes；
If so, then perform aforementioned step 103；Otherwise, holding terminal transmission to operating personnel can without PCI codes for prompting
Prompt message, so that the PCI codes that spare block may be used in operating personnel are adjusted.
The PCI code configuration methods of base station in the present embodiment determine to work as with reference to the geographical location of the base station of PCI codes to be allocated
Before the PCI codes to be distributed, and then the dispensing rate of PCI codes can be improved, reduce that the PCI codes being likely to occur are existing to conflict and mixed
Confuse, effectively save cost.
It will be appreciated that in method shown in Fig. 1, executive agent be management station including PCI code configuration devices or
Administrative center.For example, the base station for being assigned PCI codes detect PCI codes conflict/when obscuring event, triggerable management station holds
The above-mentioned method flow of row；Conflict/obscure detection alternatively, management station actively initiates PCI codes, if conflicting/obscuring thing there are PCI codes
During part, above-mentioned method flow is performed；It is redistributed alternatively, management station actively initiates PCI codes, performs above-mentioned method flow.
In an optional implementation manner, aforementioned method shown in FIG. 1 may also include following before step 101
Step 100, as shown in Figure 2：
100th, all PCI codes in the way of 54 one group of PCI codes are grouped, obtain 9 PCI code characters and one
Spare code character；
Wherein, the PCI codes in every PCI groups are continuous successively.
For example, the range of current PCI codes is 0-503, and the PCI codes of the range can be divided into 9 pieces of piecemeals (i.e. nine
Code character) and 1 spare block (i.e. a spare code character), 9 pieces of every piece of piecemeals, 54 sequence PCI codes, unallocated PCI codes are assigned to spare
Block.
1 piecemeal：1-54；
2 piecemeals：55-108；
3 piecemeals：109-162；
4 piecemeals：163-216；
5 piecemeals：217-270；
6 piecemeals：271-324；
7 piecemeals：325-378；
8 piecemeals：379-432；
9 piecemeals：433-486；
Spare block：0,487-503.
Above-mentioned 54 PCI codes of each piecemeal distribute 3 sequence codes by a base station, can distribute 18 base stations.It is spare
Block divides coverage base station/benefit blind use available for room.
In another optional realization method, the step 104 in aforementioned method shown in FIG. 1 may include following figures
In unshowned sub-step 1041 to sub-step 1044.
1041st, geographical regional center position, the geographic area center and the geographical location of the base station are determined
Distance is within a preset range.
In the present embodiment, geographic area center can also be a suitable base station geographic position, can also be aobvious
The marker of work or other building markers etc..
Determining geographic area center can be any one lattice in corresponding nine grids region, such as Fig. 3 A and Fig. 3 C institutes
Show, determining geographic area center can be any one in 1 to 9 digital affiliated area, and the present embodiment does not carry out it
It limits, adjusts as needed.
1042nd, determine that the covering of the part or all of base station in the geographic area is close according to the geographic area center
Degree.
In the present embodiment, determine that the coverage density of base station can be according to engineering parameter table (such as following table pre-stored in management station
One and table two) in base station information, and then calculated using following formula one, to know the coverage density of base station, such as
The distance between any two adjacent base station in the geographic area can be selected to calculate, and then can preferably be determined in the geographic area
The coverage density of all base stations.
In practical applications, management station can also send engineering parameter table to base station in advance and obtain request, so that base station will be internal
The engineering parameter table of storage obtains request according to the engineering parameter table and is sent to management, and then management station determines the geography according to engineering parameter table
The coverage density of part or all of base station in region.
1043rd, it is obtained according to the geographic area center, coverage density and determines nine piecemeal geography positions in nine grids
Range is put, obtains nine grids region.
1044th, the nine grids of acquisition and nine PCI code characters are corresponded.
In the present embodiment, put and be relatively fixed per case in two adjacent nine grids regions of arbitrary extension (such as Fig. 3 B and
Shown in Fig. 3 D), PCI codes can be not fixed relative position in same lattice.
That is, the corresponding PCI code character in each lattice region in all nine grids regions；Each nine grids region Zhong Gege areas
The PCI code characters in domain do not repeat；The PCI code characters for belonging to the lattice region of same position in any two nine grids region are identical.
The corresponding PCI code characters in each nine grids region are all identical in the nine grids region of arbitrary neighborhood.
It should be noted that management station pre-saves the engineering parameter table of all base stations, and then the information in engineering parameter table determines
The distance between base station so using the above method to base station distribute PCI codes.If following table one and table two are preset engineering parameter table
Table structure there are various information in the engineering parameter table structure.
Table one, engineering parameter table structure：
Table two
In addition, calculate distance algorithm (formula one) between 2 base station cells：
Formula one illustrates：
A=Lat1-Lat2 are the difference of 2 latitudes；
B=Lng1-Lng2 is the difference of 2 longitudes；
Lat1/Lng1 represents A point latitudes and longitude (base station A), and Lat2/Lng2 represents B point latitudes and longitude (base station B)；
6378.137 for earth radius, unit is km；
Result of calculation S units are km.
To be better understood from the scheme of the embodiment of the present invention, with reference to Fig. 1, Fig. 2 and following Fig. 3 A to Fig. 3 D, Fig. 4, figure
5th, Fig. 6 and Fig. 7 are described in detail.
Now net base station deployment can be equivalent to Cellular Networks, and a PCI codes piecemeal can distribute 18 base stations, i.e. maximum can form
The Cellular Networks layout (as shown in Figure 4) of 4x4, minimum suggest the Cellular Networks of 3x3 layout (as shown in Figure 5).Remaining unused 6 PCI
Code (standby code) divides coverage base station/benefit blind use available for room.
Fig. 3 A and Fig. 3 C show any one nine grids region, and each lattice region can correspond to one group in the nine grids region
PCI code characters.In a particular application, the nine grids region shown in above-mentioned Fig. 3 A can on geographical location arbitrary extension, such as Fig. 3 B
It is shown, the extension in a nine grids region of Fig. 3 A is shown in Fig. 3 B, each lattice in the nine grids region in extension at this time
The corresponding PCI code characters in region be it is constant, i.e., in fig. 3b it is assumed that " 1 " it is corresponding be first PCI code character, then the nine grids
Region extends nine or nine or more, and the position of " 1 " is fixed in the nine grids region of all extensions, i.e. first PCI code character
Position is fixed, but all PCI codes can be distributed arbitrarily in a manner of three sequence codes in first PCI code character, no
Limit the position of PCI codes in PCI code characters.Correspondingly, referring to Fig. 3 C and Fig. 3 D.
That is, 9 PCI piecemeals of above-mentioned division use nine grids mode loop configuration, each PCI piecemeals are in nine palaces
The position of lattice is fixed, and affiliated PCI codes can be sequentially allocated with arbitrary disposition, each base station by three sequence codes in PCI piecemeals.
It can be seen that the base station in arbitrary piecemeal from Fig. 3 B, add new adjacent cell and identical PCI codes occur, it be at least across it
His 2 piecemeals, if the honeycomb net layout of composition 4x4 will be likely to PCI code collision problems occur more than at least 8 layers.If group
Into the honeycomb net layout of 3x3, it to be likely to occurring PCI code collision problems more than at least 6 layers.
For this purpose, in embodiments of the present invention, it is different according to different district geographic regions base stations coverage density, between selection of base stations
Distance, can calculate a PCI codes piecemeal can distribute the coverage area of base station：
Firstth, high density covers：Usual spacing 300-500 meters of base station
A) cell-of-origin is added to identical PCI codes triggering conflict and needs at least to add 8 layers, as shown in Figure 6.Between i.e. minimum base station
Away from reaching 2400 meters, already belonging to super remote adjacent area will not be added；
B) cell-of-origin, which is added to 2, identical PCI codes cell triggering alias condition, and 3 layers of calculating are at most added by adjacent area, are schemed
Mesosphere position is base station location where cell-of-origin in 6, both sides circle position adjacent area addition 3 layers of base station location of maximum distance, can be with
See that cell-of-origin will not be added to 2 closest A base station cells.
Secondth, Midst density covers:Usual spacing 500-800 meters of base station, low-density covering：Usual base station spacing 800-1200
Rice；
For Midst density and low-density, adjacent area distance be far above high density coverage base station, it more difficult to occur PCI codes conflict/
Confounding issues.
