Technical field
The present invention relates to wireless communication technology field, more particularly to a kind of neighbor cell optimizing method and device.
Background technology
In gsm networks, in order to ensure the persistent of mobile terminal call, network can be according to the MR of reporting of user（Measurement
Report）Message switches over judgement, when meeting Locationg handoff algorithms, will generate and switch, after handover success, user will
It converses on the new channel, however the premise switched needs to define a rational adjacent area, only neighboring BS relationship is reasonable,
It just can guarantee the continuation of call.
Rational neighboring BS relationship is the premise for ensureing GSM network switching.The method of existing daily Neighborhood Optimization mainly for
Redundancy adjacent area and two aspect of leakage are analyzed and optimized, and pass through the handover measurement of neighboring interval, adjacent area to the processing of redundancy adjacent area
Between distance and neighboring interval level distribution situation be used as assessment and judge whether redundancy neighboring BS relationship, for redundancy
The judgement of adjacent area usually need to consider switching whether be delayed and whether handover failure etc., while can increase need not for redundancy adjacent area
Signaling traffic load, certain loss is caused to existing net.And for miss-configured neighboring cells, it is largely used in now netting in BA2 tables（General feelings
Under condition, BA1 tables are consistent with BA2 tables, are all neighboring BS relationship, and BA1 tables are used for cell reselection, and BA2 tables are used for switching）Middle increase
Virtual measurement frequency point after the BSIC codes corresponding to increased measurement frequency point and the frequency point, can obtain the CI of respective cell
（Cell ID）, then by manually observing the cell and cell-of-origin with the presence or absence of before and after certain switching frequency, switching
Quality, level quality etc. are judged：Level, quality before and after the cell meets certain switching frequency and switching
When, it is possible to add in neighboring cell list as real adjacent area；Another mode is the location distribution based on cell, wireless
Environment traffic forecast, distance, deflection prediction, it is believed that when these conditions are met, adjacent area can be added in as actual adjacent area
Table.Often artificial factor is too many for both approaches, without very strong foundation and reliability, often results in adjacent area addition and does not conform to
Reason, work efficiency are low.
In conclusion the implementation method in existing neighbor cell optimizing method for redundancy adjacent area and miss-configured neighboring cells at least exists
Following technical problem：
The determination methods of existing redundancy adjacent area need the handoff relation for minizone to judge whether handover delay mistake occur
Situations such as length, handover failure number are more and consider minizone distance, level distribution, process cycle is slower, and imitates
Rate is relatively low.
In 2 kinds of methods of the judgement of existing miss-configured neighboring cells, possess one for the method for virtual frequency point measurement to increase adjacent area
Fixed data foundation and reliability, but there is also certain limitations：
First：The length of BA tables is limited, if newly-increased frequency point information can be brought not without very strong purpose
Necessary workload, and need to make repeated attempts, process cycle is long, and efficiency is not high.
Secondly：The increase of virtual frequency point, without it is comprehensive the considerations of real cell website distribution and wireless environment, some are small
Area may exist leakage plus, but since method is more single or can there are certain omissions.
Again：The increase of virtual frequency point, it may be necessary to which equipment vendors personnel carry out, and third party's network optimization personnel possibly can not be into
Row operation.

Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without creative efforts
Embodiment belongs to the scope of protection of the invention.Also, following embodiment is the alternative of the present invention, embodiment
It puts in order and the number of embodiment is unrelated with the order that it preferably is carried out.
Embodiment 1
The present embodiment provides a kind of neighbor cell optimizing method, this method is suitble to be deployed in one and communication interface Abis interface can
On the platform interacted or on device.As shown in Figure 1, this method includes：
Step 101, covering relation matrix is established according to the measurement report MR data got from communication interface.
Above-mentioned communication interface is specially Abis interface, since the MR data that terminal is sent are to be reported to net by Abis interface
Network side, therefore the MR data of terminal transmission need to can be only truncated in the present embodiment from the signaling by Abis interface.
Wherein, the covering relation matrix that step 101 includes establishing can be existed in a manner of covering relation matrix table,
Mainly include three parts data in the matrix table.1st, minizone relationship degree/probability of interference；2nd, main serving cell and neighbor cell
Level difference counts；3rd, the carrier/interface ratio between main serving cell and each neighbor cell（That is C/I is the useful signal received（Main clothes
Business cell）Level and all non-useful signals（Neighbor cell）In general the ratio of level exists with the generally requirement of frequency carrier/interface ratio
C/I>9db, here borrow C/I relation, establish the C/I relations between cell and cell in MR data, to weigh cell it
Between disturbed condition.）Wherein, C represents the level value of main serving cell, and I represents the level value of neighbor cell.Wherein, due to upper
Stating 1 and 2 data can directly get from MR data, and this will not be repeated here.It can be divided into two parts for the neighbor cell in 3
It obtains.A part is by reporting directly obtained neighbor cell in MR data；Another part is by meeting virtual subdistrict
The virtual neighbor cell that the mode of this virtual compensation measurement of condition is screened, virtual compensation measurement method obtains adjacent
Cell is miss-configured neighboring cells in order to prevent.
Above-mentioned steps 101 can be realized in the following way as a result,：
The main serving cell reported in MR data and the level value of its neighbor cell are obtained from communication interface, main service is small
Area and the respective level value in its neighbor cell are arranged according to the size of carrier/interface ratio, and record and formed covering relation matrix.
Further, which further includes：The level value of all cells reported in MR data is obtained from communication interface, such as
The carrier/interface ratio of the level value of wherein arbitrary two cell of fruit meets virtual subdistrict condition, then using arbitrary two cell as virtual main
In serving cell and its neighbor cell record all covering relation matrixes.
Specifically, MS can report the neighbor cell of 6 peak signals measured in communication process, and main service is small
The level of area and corresponding 6 neighbor cells measured directly carries out sampled point according to the magnitude relationship of C/I and records in detail, and
Such C/I relations are summarized into storage, form a covering relation matrix table（This is simply a part of）；On the other hand, definition is worked as
Main serving cell adjacent area adjacent with any one meets in MR data【S_Rxlev_sub_down（Main serving cell）-N_Rxlev_
Sub_down (neighbor cell)】>-6DB】I.e.：C/I>Virtual to build measurement relation during -6DB, relation in this way can obtain
Go out such conclusion：It gives one example to illustrate：If A cells and B cells possess measurement relation, B cells and C cells
Possesses measurement relation, but beginning A cells and C cells do not measure relation, pass through such a (C/I described above>-
6DB) the virtually formation of structure measurement relation, when meeting main serving cell and adjacent cell difference in -6DB, it is possible to it is small to establish A
Area and the virtual measurement relation of C cells, i.e., using A cells and C cells as virtual main serving cell and its neighbor cell, with such
It pushes away and such mode is expanded into the whole network, it becomes possible to obtain a complete virtual compensation measurement cell（It is subsequently adjacent as leakage
The sampled point reference in area）, by the part summarize storage and it is above-mentioned according to C/I relations size storage covering relation matrix table into
Row merges, and is formed a complete covering relation matrix table.
Step 102, the carrier/interface ratio in covering relation matrix（That is main serving cell and the C/I of each neighbor cell）It calculates
Main serving cell and the neighboring BS relationship degree coefficient of a wherein neighbor cell.
The step can be realized in the following way：
Carrier/interface ratio in covering relation matrix calculates main serving cell and is weighed respectively with the co-channel interference of each neighbor cell
Weight；Using the co-channel interference weight as the main serving cell and the first neighboring BS relationship degree coefficient of each neighbor cell.Specifically
It can refer to following formula one
Co-channel interference weight：Q=FER（C/I）=1/(1+e-0.357+0.248C/I) （One）
Wherein, Q is the co-channel interference weight of a certain adjacent area；
C/I is main serving cell and the carrier/interface ratio of a certain adjacent area；
FER:Frame error rate；With C/I there are certain correspondence, under normal circumstances, frame error rate is big, and C/I is poor.Physical relationship is such as
Described by above-mentioned formula one.
Further, specifically further include：Believed according to the frequency range of the main serving cell and each neighbor cell provided in MR data
Breath and cell type information, according to default frequency range weight coefficient table and cell type weight coefficient table search to main serving cell
Respectively with the second neighboring BS relationship degree coefficient of each neighbor cell；According to the first neighboring BS relationship degree coefficient and the second neighboring BS relationship
It spends coefficient and calculates the main serving cell neighboring BS relationship degree coefficient with each neighbor cell respectively.
The neighboring BS relationship degree coefficient of a certain cell in this step can also be calculated from the aspect of two.On the one hand consider
The weight of C/I and the cell frame error rate of main serving cell（FER）Between the obtained co-channel interference weight of relation（That is the first adjacent area
Relationship degree coefficient）, on the other hand consider frequency range weight coefficient and cell type weight coefficient（That is the second neighboring BS relationship degree coefficient）,
The neighboring BS relationship degree coefficient of first neighboring BS relationship degree coefficient * the second neighboring BS relationship degree coefficient=neighbor cell.
Specifically, the first neighboring BS relationship degree coefficient is according to the relation of C/I and combination in covering relation matrix table before
Cell frame error rate（FER）Relation be determined.Specific reason, as shown in Fig. 2, by the study found that FER and C/I, exists
Certain weight relationship.With reference to the weight relationship of FER and C/I, can summarize to obtain the weight of the C/I between arbitrary two cell,
So as to combine between cell the quantity of the sampled point that C/I is formed between cell and cell in covering relation matrix table, it is accurate to obtain
The first neighboring BS relationship degree coefficient（Circular is with reference to above-mentioned formula one）.There is the first neighboring BS relationship degree coefficient, it can
Using tentatively as the correlation basis for estimation of adjacent area between cell, reference following table one.
Table one
Wherein, certain cell in table one may be considered main serving cell, and more than section 1-12 may be considered adjacent small
Area.Weight Q can refer to above-mentioned formula one and be calculated.
Further, in order to being more accurately obtained the neighboring BS relationship degree coefficient of minizone, it is also necessary to reference to cell
The second neighboring BS relationship degree coefficient is weighed and then obtained to itself attribute and relation.Normal conditions cell have be divided into 900M and
The cell of 1800M types, and the cell of indoor and outdoors type is also divided into, therefore a cell can possess two types simultaneously
（I.e.：Frequency range type and cell type）.Due between existing net cell each other adjacent area when, for 900 cells and 1800 cells, interior
With outdoor cell in combination and during neighboring BS relationship each other, there are certain priority, therefore we are based between cell
Type of relationship further distributes certain cell type weight.This part is on the one hand frequency range weight system from the aspect of two
Number, is on the other hand cell type weight coefficient.
It is the definition of frequency range weight coefficient as shown in following table two：
Table two
It is the definition of cell type weight coefficient as shown in following table three：
Table three
The content of above-mentioned table two and table three can be pre-defined on platform, investigate certain neighbor cell and main serving cell
The second neighboring BS relationship degree coefficient when being, the above-mentioned type, the frequency of main serving cell and neighbor cell can be obtained from MR data
Section etc., by searching for above-mentioned table two and three, by the adjacent area of the cell frequency range coefficient * cell types weight coefficient of lookup result=second
Relationship degree coefficient, it is possible thereby to the neighboring BS relationship degree coefficient between being accurately obtained cell.Therefore both the above factor is considered
The influence of first neighboring BS relationship degree coefficient and the second neighboring BS relationship degree coefficient just establishes minizone accurately neighboring BS relationship degree system
Number, convenient for making a decision in next step.In preferred embodiment, the neighboring BS relationship degree coefficient calculated can be recorded in set covering theory table
Corresponding cell, with the cell association, set covering theory table as shown in Figure 5.
Step 103, according to the neighboring BS relationship degree coefficient and optimizing cells coefficient determine to delete or add the optimization of cell
Scheme.
Wherein, neighboring BS relationship degree coefficient will take the data of its absolute value.Optimizing cells coefficient includes：Website distance（Cell
The distance between, the distance between arbitrary two cell can be pre-stored on platform, lift analog value when calculating）And/or cell
Switching times（The number of certain adjacent area is switched to, which can count or take pre- according to the switching times reported in MR data
The mode of definition）.
Prioritization scheme in the present embodiment includes determining whether to add the optimization of the miss-configured neighboring cells when detecting miss-configured neighboring cells
Scheme and while detecting redundancy adjacent area, determine whether to delete the prioritization scheme of the redundancy adjacent area.
The step 103 can be outdoor macro station type or the difference of indoor room classifying type according to neighbor cell, pass through respectively
Following manner realization, including：
When dividing cell in neighbor cell for room, the neighboring BS relationship degree coefficient of neighbor cell is arranged according to order from small to large
Row, and divide cell neighboring BS relationship degree thresholding with room（Such as 25）For boundary, neighbor cell is divided into addition adjacent area group（Mainly it would be possible to
The cell being added in neighboring cell list is arranged to addition adjacent area group）With deletion adjacent area group（Mainly it would be possible to from neighboring cell list
The cell of deletion is arranged to addition adjacent area group）；Website distance will be met in addition adjacent area group（Such as whether less than 0.5KM）And adjacent area
Relationship degree coefficient condition（As whether neighboring BS relationship degree coefficient is more than 0.005）Neighbor cell be added to the neighboring cell list of base station
In；Meet website distance by deleting in the group of adjacent area（Such as whether more than 0.5KM）, cell switching times（Such as whether less than 200
It is secondary）With neighboring BS relationship degree coefficient condition（As whether neighboring BS relationship degree coefficient is less than 0.002）Neighbor cell from the adjacent area of base station
List is deleted.
Neighbor cell be macro station cell when, by the neighboring BS relationship degree coefficient of neighbor cell according to from small to large order arrange
Row, and using macro station cell neighboring BS relationship degree thresholding as boundary（Such as 31）, neighbor cell is divided into addition adjacent area group and deletes adjacent area group；
Website distance will be met in addition adjacent area group（Such as whether less than 1.0KM）With neighboring BS relationship degree coefficient condition（Such as neighboring BS relationship degree
Whether coefficient is more than 0.01）Neighbor cell be added in the neighboring cell list of base station；Meet website distance by deleting in the group of adjacent area
（Such as whether more than 1.0KM）, cell switching times（Such as whether less than 200 times）With neighboring BS relationship degree coefficient condition（Such as adjacent area
Whether relationship degree coefficient is less than 0.003）Neighbor cell deleted from the neighboring cell list of base station.
Specifically, there are the complete set covering theory table in minizone and neighboring BS relationship degree coefficient, it is possible to start to judge
Rationality relationship between adjacent area.In gsm networks, agreement provides, for arbitrary cells BA2 tables BCCH channel of broadcast control frequency
The addition of point does not exceed 31, therefore for outdoor cell, for the neighboring BS relationship degree coefficient in set covering theory table（Inverted order is arranged
Row）And delimited according to the threshold value of 31 positions, before 31（Non-existing adjacent area）Carry out the increase of miss-configured neighboring cells；
For the adjacent area after 31（Existing adjacent area）It is deleted.Certainly, in the judgement for increasing and deleting, we also need to consider
