Detailed description of the invention
It should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not used to limit
Determine the present invention.
The present invention provides a kind of neighbor cell optimizing method, and with reference to Fig. 1, Fig. 1 is neighbor cell optimizing method of the present invention the
The schematic flow sheet of one embodiment, in the first embodiment, described neighbor cell optimizing method comprises the following steps:
Step S100, the data gathering soft handover and virtual switching.
Terminal is constantly to RNC (Radio Network Controller, radio network controller) reporting measurement
Report, wherein, terminal can be described as UE (User Equipment, user terminal), it is also possible to is referred to as mobile
Terminal (Mobile terminal), mobile subscriber equipment etc., terminal not only can be to the monitoring of matched adjacent zone
In collection, cell measures report, it is possible to measure the cell in the detection collection of non-configuring adjacent cell relation
With report.In the present embodiment, terminal actually occurs in foreground gathers several days switching and detection collection are sent out
Raw virtual switch data.Described soft handover refer to when the carrier frequency of pilot channel is identical cell it
Between channel switching.Described virtual switching refers to false switching, and virtual switching can cause the waste of resource.
Step S200, according to the soft handover gathering and the data of virtual switching and default handoff threshold,
Obtain the PRELIMINARY RESULTS of Neighborhood Optimization.
Terminal, according to the soft handover gathering and the data of virtual switching and default handoff threshold, obtains neighbour
The PRELIMINARY RESULTS that district optimizes.Wherein, the handoff threshold preset can be the number of times of switching, it is also possible to be to cut
The ratio changed, the PRELIMINARY RESULTS of Neighborhood Optimization can be the corresponding neighboring BS relationship adding or deleting cell pair,
Also can be that the data of adjacent area carry out filtration etc., for example, if terminal detects the virtual switching of cell pair
Number of times less than preset handoff threshold and virtual switching ratio less than preset switching proportion thresholding when,
Then determine that the data of described virtual switching, to for invalid adjacent area pair, are filtered by described cell.Wherein,
Forming cell pair between two cells, for example, main plot and adjacent cell can form cell pair.
The adjacent area parameter that step S300, basis are preset, is adjusted to the PRELIMINARY RESULTS of Neighborhood Optimization.
The PRELIMINARY RESULTS of the Neighborhood Optimization obtaining, according to the adjacent area parameter pre-setting, is adjusted by terminal,
Described default adjacent area parameter can be red-black list, adjacent area interworking, adjacent area number thresholding and scrambler multiplexing
In the synthesis of one or more, wherein the priority orders of adjacent area parameter is with red-black list as elder generation, for example,
If being not added with A-B cell in the PRELIMINARY RESULTS of Neighborhood Optimization when being neighborhood, and at red-black list
In Red List in when having A-B cell, then adding A-B cell is neighborhood.
The present embodiment provide neighbor cell optimizing method, solve authority rate of specific gravity arrange difficulty and with reality
The on-the-spot problem that there is deviation, improves Neighborhood Optimization efficiency, and accuracy rate is high.
As in figure 2 it is shown, the refinement schematic flow sheet that Fig. 2 is step S200 described in Fig. 1, described step S200
Including:
If step S210 detects the number of times of the virtual switching of cell pair less than the handoff threshold preset and void
When intending the ratio of switching less than the switching proportion thresholding preset, it is determined that described cell is to for invalid adjacent area
Right, the data of described virtual switching are filtered.
If terminal detects the number of times of the virtual switching of cell pair less than the handoff threshold preset and virtual switching
Ratio less than the switching proportion thresholding preset when, it is determined that described cell is to for invalid adjacent area pair, right
The data of described virtual switching filter.Wherein, the ratio of virtual switching is to cut with the virtual of cell pair
Change number of times summation as molecule, the virtual switching times of main plot and the number of times summation of soft handover as denominator,
The ratio calculated, default handoff threshold and the switching proportion thresholding preset can be according to the realities of user
Border needs to pre-set, it is also possible to suitably adjusts in actual motion, for example, can will switch
Threshold sets is 50 times, and switching proportion threshold sets is 2%, then if be detected that cell pair is virtual
The number of times of switching is less than the ratio of 50 times and virtual switching less than 2%, then confirm described cell to for nothing
The data of the virtual switching of described cell are filtered by the cell pair of effect.
If step S220 detects the number of times of the virtual switching of cell pair more than or equal to the switching door preset
Limit, the ratio of virtual switching more than or equal to the switching proportion thresholding preset and described cell to not configuring neighbour
During cell relation, then corresponding add described cell to for neighboring BS relationship.
The interpolation cell that terminal pre-sets is as follows to the entry criteria for neighboring BS relationship:
First, the number of times of the virtual switching of cell pair is more than or equal to the handoff threshold preset；
2nd, the ratio of virtual switching is more than or equal to the switching proportion thresholding preset；
3rd, described cell is to non-configuring adjacent cell relation.
Wherein, the ratio of virtual switching is using the virtual switching times summation of cell pair as molecule, main little
The number of times summation of the virtual switching times in district and soft handover as denominator, the ratio calculated, default
Handoff threshold and the switching proportion thresholding preset can pre-set according to being actually needed of user.If
Three above conditions are set up simultaneously, then terminal is corresponding adds described cell to for neighboring BS relationship.
As shown in table 1, cell A has filtered the data of virtual switching according to step S100 and step S200
Afterwards, count cell A soft handover and virtual switching times sum with frequency occurring is 7641, cell A
Utilization rate be 89%；List all homogeneous-frequency adjacent-domain relations with cell A or occur to switch little with frequency
The information in district.
Table 1
Need to illustrate a bit, soft handoff data directly have recorded main plot and adjacent cell (N1～N16)
Cell ID, but the simply main plot ID of virtual switch data record and adjacent area scrambler switch time
Number, therefore, for virtual switching, in addition it is also necessary to find out this scrambler cell M closest with cell A.
Assume that the virtual switching that terminal is arranged increases cell and to the thresholding for neighboring BS relationship is: switching proportion door
Limit S=1%, handoff threshold C=50, then at the beginning of the cell correspondence that in above table, last two void are cut is given
The Neighborhood Optimization suggestion begun is as shown in table 2:
Table 2
If step S230 detects the number of times of the virtual switching of cell pair less than the handoff threshold preset, void
Intend switching ratio less than preset switching proportion thresholding, cell pair utilization rate more than or equal to preset
When proportion of utilization thresholding and described cell are to configured neighboring BS relationship, then the corresponding neighbour deleting described cell pair
Cell relation.
The entry criteria of the neighboring BS relationship of the deletion cell pair that terminal pre-sets is as follows:
First, the number of times of the virtual switching of cell pair is less than the handoff threshold preset；
2nd, the ratio of virtual switching is less than the switching proportion thresholding preset；
3rd, the utilization rate of cell pair is more than or equal to the proportion of utilization thresholding preset；
4th, cell is to having been configured as neighboring BS relationship.
Wherein, the ratio of virtual switching is using the virtual switching times summation of cell pair as molecule, main little
The number of times summation of the virtual switching times in district and soft handover as denominator, the ratio calculated, default
Handoff threshold and the switching proportion thresholding preset can pre-set according to being actually needed of user.If
Four above conditions are set up simultaneously, then the corresponding neighboring BS relationship deleting described cell pair of terminal.
As shown in table 3, it is assumed that the handoff threshold N=200 that terminal is arranged, switching proportion thresholding is 0.2%,
The utilization rate thresholding 80% of main adjacent cell, then the neighboring BS relationship needs simultaneously meeting these three thresholding are deleted
Removing, therefore, initial optimization suggestion is updated to as follows:
Table 3
With further reference to Fig. 3, Fig. 3 is the refinement flow process signal of the first embodiment of step S300 described in Fig. 1
Figure, described step S300 includes:
Step S310, according to the PRELIMINARY RESULTS of Neighborhood Optimization obtaining and default red-black list, be described
Cell is to configuring adjacent cell relation.
If the described cell of step S320 is in default Red List and when being not added into neighboring BS relationship, then
Corresponding add described cell to for neighboring BS relationship.
If the described cell of step S330 is in default Red List and the neighboring BS relationship of described cell pair is deleted
Except when, then again add the neighboring BS relationship of described cell pair.
The PRELIMINARY RESULTS of the Neighborhood Optimization according to acquisition for the terminal and the red-black list pre-setting, enter to adjacent area
One-step optimization, for example: if A-B cell is to the preliminary Neighborhood Optimization being preset in Red List form and above
Result do not adds A-B cell to for neighboring BS relationship, then by A-B cell to being added to neighboring BS relationship；As
Really A-B cell is to the neighboring BS relationship being arranged in Red List form and deleting A-B cell pair, then again add
The neighboring BS relationship of A-B cell pair, its purpose is in order to ensure A-B cell to necessarily joining for neighboring BS relationship.Similar
If the optimum results being preset in blacklist form and above has been added A-C cell pair by ground A-B cell
For neighboring BS relationship, then just delete the neighboring BS relationship of A-C cell pair；If A-B cell is to being preset at black name
In single form and optimum results above is not added with A-C cell to for neighboring BS relationship, then just remain in that
A-C cell is not to having neighboring BS relationship.
On the basis of table 3 above optimizes example, it is assumed that default Red List has the record of A-M3, black
List has the record of A-N5, then Neighborhood Optimization result is updated to as shown in table 4:
Table 4
With further reference to Fig. 4, Fig. 4 is the refinement flow process signal of the second embodiment of step S300 described in Fig. 1
Figure, described step S300 includes:
Step S340, the PRELIMINARY RESULTS according to the Neighborhood Optimization obtaining, the neighbour to the described cell pair added
Cell relation does interworking process.
If the described cell that step S350 is added is not to existing reverse adjacent area pair, then add described reverse neighbour
District pair.
If the described reverse cell of step S360 is in default Red List and the neighbour of described reverse cell pair
When cell relation is deleted, then again add the neighboring BS relationship of described reverse cell pair.
Terminal is according to the PRELIMINARY RESULTS of the Neighborhood Optimization obtaining, the neighboring BS relationship to the described cell pair added
Doing interworking process, the treatment principle of adjacent area interworking is: on the premise of not violating red-black list restriction, add
Add the adjacent area pair of neighboring BS relationship, if there is no reverse adjacent area, then add reverse adjacent area pair；If it is described
Reverse cell in default Red List and when the neighboring BS relationship of described reverse cell pair deletes, then weighs
The neighboring BS relationship of newly added described reverse cell pair.
Continue the example of table 4, it is assumed that optimum results does not exist interpolation M1-A neighboring BS relationship or joined neighbour
Cell relation does not exist M1-A, then A-M1 will Cheng Dan join after being configured to adjacent area, it is therefore desirable to increase
The neighboring BS relationship of M1-A.Assume optimum results exists N5-A adjacent area to increase, according to interworking principle,
The A-N5 of table 4 needs to be added to neighboring BS relationship, but again owing to A-N5 is present in blacklist, with black
List is preferential, and therefore the neighboring BS relationship of A-N5 need nonetheless remain for deleting, and optimum results is as shown in table 5 further:
Table 5
As it is shown in figure 5, the schematic flow sheet that Fig. 5 is neighbor cell optimizing method the second embodiment of the present invention,
On the basis of first embodiment, the neighbor cell optimizing method of the second embodiment offer, described step S300 includes:
Step S300A, restriction adjacent area number, if the adjacent area number of described cell pair is not in default adjacent area
During the scope of number thresholding, then adjust adjacent area number in the range of the number thresholding of adjacent area.
Terminal preset adjacent area number thresholding, limits adjacent area number, if the adjacent area number of described cell pair does not exists
During the scope of adjacent area number thresholding preset, then adjust adjacent area number in the range of the number thresholding of adjacent area.
First, when adjacent area number (the adjacent area number of the adjacent area number-deletion of existing adjacent area number+increase)-
Maximum N of big adjacent area number thresholding > 0 when, then need part to delete the neighbour of the described cell pair added
Cell relation.
If the neighboring BS relationship of the described cell pair that a has added is present in Red List, then that adds is described little
The neighboring BS relationship in district pair preferentially retains.
B, consider the restriction of Red List after, by the neighboring BS relationship of the described cell pair of remaining interpolation, according to
The void of neighboring BS relationship cuts ratio descending；
If c, is positioned at after the sequence that will have added by distance ascending order secondary arrangement when void is cut and is in equal proportions
The neighboring BS relationship of rearmost N number of cell pair is deleted.
2nd, as adjacent area number (the adjacent area number of the adjacent area number-deletion of existing adjacent area number+increase)-neighbour
The minimum M of district's number thresholding < when 0, then needs part to add the deleted neighborhood of adjacent area.
If it the deleted neighboring BS relationship of a, is present in blacklist, then the preferential neighbour deleting described cell pair
Cell relation.
B, consider blacklist restriction after, by the remaining neighboring BS relationship having deleted cell pair, according to adjacent area
The soft of relation cuts the arrangement of ratio ascending order.
C, soft cut be in equal proportions when by distance descending secondary arrangement, last by being positioned at after deleted sequence
The neighboring BS relationship of M the cell pair in face adds again.
Assume maximum M=31 of adjacent area number thresholding, minimum of a value N=15 of adjacent area number thresholding.At this
Under the restriction of two thresholdings, owing to adjacent area number is inadequate, according to the rule limiting adjacent area number above, front
In the suggestion of face Neighborhood Optimization, the neighboring BS relationship of A-N3 and A-N4 is become by deletion and does not delete.Though and A-N5
Right switching proportion is bigger, but owing to, in blacklist, A-N5 need nonetheless remain for deleting, further excellent
Change result as shown in table 6:
Table 6
As shown in Figure 6, Fig. 6 is the schematic flow sheet of neighbor cell optimizing method the 3rd embodiment of the present invention,
On the basis of first embodiment, the neighbor cell optimizing method of the 3rd embodiment offer, described step S300 includes:
If the described cell that step S300B is added is to when existing scrambler multiplexing, then delete described cell pair
Neighboring BS relationship.
Terminal, on the neighboring BS relationship of additions and deletions, checks scrambler multiplexed situation further.If that adds is described little
When the neighboring BS relationship in district pair exists scrambler multiplexing, then need to delete the neighboring BS relationship of described cell pair, to reach
To the purpose eliminating scrambler multiplexed path.In the present embodiment, carry out as a example by checking two layers of scrambler multiplexing
Explanation.
Assuming that cell A is configured with B and does adjacent area, cell B is configured with C and does adjacent area, then cell C is exactly
Two layers of neighboring BS relationship of cell A.As described in Table 7, A-C has following four kinds of paths, and A--> B represents A
Being configured with B is adjacent area, A <--it is adjacent area that B represents that B is configured with A.First three is wherein only had to be effective road
Footpath, say, that in the path of first three situation, when A and C is with when frequently with scrambler, A and C can exist
Interference, i.e. there is scrambler multiplexing in A and C.
| Adjacent area chain | A--B | B--C | Attribute |
| 1 | <-- | <-- | Efficient combination |
| 2 | <-- | --> | Efficient combination |
| 3 | --> | --> | Efficient combination |
| 4 | --> | <-- | Invalid combination |
Table 7
As a example by adjacent area chain 1, when there is scrambler multiplexing in A and C, and B <--C is that Neighborhood Optimization is built
During the adjacent area pair increasing in view, then in order to eliminate scrambler multiplexing, B <--this neighboring BS relationship increasing of C should
This deletion.Check in the whole network, find all links that there are two layers of scrambler multiplexing, if in these links
Containing when advising the adjacent area increasing, then need the adjacent area increasing these suggestions to delete, reach elimination scrambler
The purpose of multiplexing.

It is less than the ratio of 50 times and virtual switching less than 2% to the number of times of virtual switching of cell pair, then confirm
The data of the virtual switching of described cell, to for invalid cell pair, are filtered by described cell.
The interpolation cell that the adding device 22 of terminal pre-sets is to the following institute of entry criteria for neighboring BS relationship
Show:
First, the number of times of the virtual switching of cell pair is more than or equal to the handoff threshold preset；
2nd, the ratio of virtual switching is more than or equal to the switching proportion thresholding preset；
3rd, described cell is to non-configuring adjacent cell relation.
Wherein, the ratio of virtual switching is using the virtual switching times summation of cell pair as molecule, main little
The number of times summation of the virtual switching times in district and soft handover as denominator, the ratio calculated, default
Handoff threshold and the switching proportion thresholding preset can pre-set according to being actually needed of user.If
Three above conditions are set up simultaneously, then terminal is corresponding adds described cell to for neighboring BS relationship.
As shown in table 1, cell A has filtered the data of virtual switching according to step S100 and step S200
Afterwards, count cell A soft handover and virtual switching times sum with frequency occurring is 7641, cell A
Utilization rate be 89%；List all homogeneous-frequency adjacent-domain relations with cell A or occur to switch little with frequency
The information in district.
Need to illustrate a bit, soft handoff data directly have recorded main plot and adjacent cell (N1～N16)
Cell ID, but the simply main plot ID of virtual switch data record and adjacent area scrambler switch time
Number, therefore, for virtual switching, in addition it is also necessary to find out this scrambler cell M closest with cell A.
Assume that the virtual switching that terminal is arranged increases cell and to the thresholding for neighboring BS relationship is: switching proportion door
Limit S=1%, handoff threshold C=50, then at the beginning of the cell correspondence that in above table, last two void are cut is given
The Neighborhood Optimization suggestion begun is as shown in table 2.
The following institute of entry criteria of the neighboring BS relationship deleting the deletion cell pair that unit 23 pre-sets of terminal
Show:
First, the number of times of the virtual switching of cell pair is less than the handoff threshold preset；
2nd, the ratio of virtual switching is less than the switching proportion thresholding preset；
3rd, the utilization rate of cell pair is more than or equal to the proportion of utilization thresholding preset；
4th, cell is to having been configured as neighboring BS relationship.
Wherein, the ratio of virtual switching is using the virtual switching times summation of cell pair as molecule, main little
The number of times summation of the virtual switching times in district and soft handover as denominator, the ratio calculated, default
Handoff threshold and the switching proportion thresholding preset can pre-set according to being actually needed of user.If
Four above conditions are set up simultaneously, then the corresponding neighboring BS relationship deleting described cell pair of terminal.
As shown in table 3, it is assumed that the handoff threshold N=200 that terminal is arranged, switching proportion thresholding is 0.2%,
The utilization rate thresholding 80% of main adjacent cell, then the neighboring BS relationship needs simultaneously meeting these three thresholding are deleted
Removing, therefore, initial optimization suggestion is updated to shown in table 3.
As it is shown in figure 9, the functional module signal of the first embodiment that Fig. 9 is adjusting module described in Fig. 7
Figure, the adjusting module 30 that first embodiment provides includes:
Dispensing unit 31, for the PRELIMINARY RESULTS according to the Neighborhood Optimization obtaining and the red-black list preset,
For described cell to configuring adjacent cell relation；
Red List unit 32, if for described cell in default Red List and be not added into adjacent area close
When being, then corresponding add described cell to for neighboring BS relationship；If described cell in default Red List and
When the neighboring BS relationship of described cell pair is deleted, then again add the neighboring BS relationship of described cell pair.
The PRELIMINARY RESULTS of the Neighborhood Optimization according to acquisition for the dispensing unit 31 of terminal and the red-black name pre-setting
Single, adjacent area is optimized further, for example: if the Red List unit 32 A-B cell of terminal is red to being preset at
Preliminary Neighborhood Optimization result in list form and above do not adds A-B cell to for neighboring BS relationship, then
By A-B cell to being added to neighboring BS relationship；If A-B cell is to being arranged in Red List form and delete
The neighboring BS relationship of A-B cell pair, then add the neighboring BS relationship of A-B cell pair again, and its purpose is in order to ensure
A-B cell is to necessarily joining for neighboring BS relationship.If similarly A-B cell to being preset in blacklist form and
Optimum results above has added A-C cell to for neighboring BS relationship, then just delete the adjacent area of A-C cell pair
Relation；If A-B cell is not added with A-C cell to the optimum results being preset in blacklist form and above
To for neighboring BS relationship, then just remain in that A-C cell to there is no neighboring BS relationship.
On the basis of table 3 above optimizes example, it is assumed that default Red List has the record of A-M3, black
List has the record of A-N5, then Neighborhood Optimization result is updated to as shown in table 4.
As shown in Figure 10, Figure 10 is that the functional module of the second embodiment of adjusting module described in Fig. 7 is shown
Being intended to, institute's mould preparation block 30 that the second embodiment provides includes:
Interworking unit 33, for the PRELIMINARY RESULTS according to the Neighborhood Optimization obtaining, to the described cell added
To neighboring BS relationship do interworking process；
Reverse adjacent area is to adding device 34, if for the described cell added to there is not reverse adjacent area pair,
Then add described reverse adjacent area pair；
Reverse adjacent area counterweight adding device 35, if for described reverse cell in default Red List and
When the neighboring BS relationship of described reverse cell pair is deleted, then the adjacent area again adding described reverse cell pair is closed
System.
The interworking unit 33 of terminal is according to the PRELIMINARY RESULTS of the Neighborhood Optimization obtaining, to the described cell added
To neighboring BS relationship do interworking process, the treatment principle of adjacent area interworking is: limit not violating red-black list
On the premise of, add the adjacent area pair of neighboring BS relationship；Reverse adjacent area to adding device 34 if be detected that do not deposit
In reverse adjacent area, then add reverse adjacent area pair；Reverse adjacent area counterweight adding device 35 is if be detected that described
Reverse cell in default Red List and when the neighboring BS relationship of described reverse cell pair deletes, then weighs
The neighboring BS relationship of newly added described reverse cell pair.
Continue the example of table 4, it is assumed that optimum results does not exist interpolation M1-A neighboring BS relationship or joined neighbour
Cell relation does not exist M1-A, then A-M1 will Cheng Dan join after being configured to adjacent area, it is therefore desirable to increase
The neighboring BS relationship of M1-A.Assume optimum results exists N5-A adjacent area to increase, according to interworking principle,
The A-N5 of table 4 needs to be added to neighboring BS relationship, but again owing to A-N5 is present in blacklist, with black
List is preferential, and therefore the neighboring BS relationship of A-N5 need nonetheless remain for deleting, and optimum results is as shown in table 5 further.
The adjusting module 30 providing with further reference to Fig. 7, the present embodiment, described adjusting module 30 is additionally operable to
Limit adjacent area number, if the adjacent area number of described cell pair is not when the scope of default adjacent area number thresholding,
Then adjust adjacent area number in the range of the number thresholding of adjacent area.
The adjusting module 30 preset adjacent area number thresholding of terminal, limits adjacent area number, if described cell pair
Adjacent area number not when the scope of default adjacent area number thresholding, then adjusts adjacent area number in adjacent area number
In the range of thresholding.
First, when adjacent area number (the adjacent area number of the adjacent area number-deletion of existing adjacent area number+increase)-
Maximum N of big adjacent area number thresholding > 0 when, then need part to delete the neighbour of the described cell pair added
Cell relation.
If the neighboring BS relationship of the described cell pair that a has added is present in Red List, then that adds is described little
The neighboring BS relationship in district pair preferentially retains.
B, consider the restriction of Red List after, by the neighboring BS relationship of the described cell pair of remaining interpolation, according to
The void of neighboring BS relationship cuts ratio descending；
If c, is positioned at after the sequence that will have added by distance ascending order secondary arrangement when void is cut and is in equal proportions
The neighboring BS relationship of rearmost N number of cell pair is deleted.
2nd, as adjacent area number (the adjacent area number of the adjacent area number-deletion of existing adjacent area number+increase)-neighbour
The minimum M of district's number thresholding < when 0, then needs part to add the deleted neighborhood of adjacent area.
If it the deleted neighboring BS relationship of a, is present in blacklist, then the preferential neighbour deleting described cell pair
Cell relation.
B, consider blacklist restriction after, by the remaining neighboring BS relationship having deleted cell pair, according to adjacent area
The soft of relation cuts the arrangement of ratio ascending order.
C, soft cut be in equal proportions when by distance descending secondary arrangement, last by being positioned at after deleted sequence
The neighboring BS relationship of M the cell pair in face adds again.
Assume maximum M=31 of adjacent area number thresholding, minimum of a value N=15 of adjacent area number thresholding.At this
Under the restriction of two thresholdings, owing to adjacent area number is inadequate, according to the rule limiting adjacent area number above, front
In the suggestion of face Neighborhood Optimization, the neighboring BS relationship of A-N3 and A-N4 is become by deletion and does not delete.Though and A-N5
Right switching proportion is bigger, but owing to, in blacklist, A-N5 need nonetheless remain for deleting, further excellent
Change result as shown in table 6.
The adjusting module providing with further reference to Fig. 7, the present embodiment, if described adjusting module 30 is additionally operable to
The described cell added to when there is scrambler multiplexing, then deletes the neighboring BS relationship of described cell pair.
The adjusting module 30 of terminal, on the neighboring BS relationship of additions and deletions, checks scrambler multiplexed situation further.If
When the neighboring BS relationship of the described cell pair added exists scrambler multiplexing, then need to delete the neighbour of described cell pair
Cell relation, to reach to eliminate the purpose of scrambler multiplexed path.In the present embodiment, to check two layers of scrambler
Illustrate as a example by multiplexing.
Assuming that cell A is configured with B and does adjacent area, cell B is configured with C and does adjacent area, then cell C is exactly
Two layers of neighboring BS relationship of cell A.As described in Table 7, A-C has following four kinds of paths, and A--> B represents A
Being configured with B is adjacent area, A <--it is adjacent area that B represents that B is configured with A.First three is wherein only had to be effective road
Footpath, say, that in the path of first three situation, when A and C is with when frequently with scrambler, A and C can exist
Interference, i.e. there is scrambler multiplexing in A and C.
As a example by adjacent area chain 1, when there is scrambler multiplexing in A and C, and B <--C is that Neighborhood Optimization is built
During the adjacent area pair increasing in view, then in order to eliminate scrambler multiplexing, B <--this neighboring BS relationship increasing of C should
This deletion.Check in the whole network, find all links that there are two layers of scrambler multiplexing, if in these links
Containing when advising the adjacent area increasing, then need the adjacent area increasing these suggestions to delete, reach elimination scrambler
The purpose of multiplexing.
