Description
Technical field
The present invention relates to communication technical field, particularly relate to a kind of neighbor cell optimizing method and device of communication Network Based.
Background technology
Neighborhood Optimization is one of main work of lifting mobile cellular network travelling performance, can ensure that user is in moving process, takies most suitable community all the time, obtains the most reasonably covering and best network service.In gsm networks, Neighborhood Optimization is the important means reducing network call drop, improve network interferences, promote speech quality.
In existing neighbor cell optimizing method, optimize expert (Neighboring Cell List Optimization Expert, hereinafter referred to as NOX) with the adjacent cell list of the immediate Ericsson of this programme.The program by collecting mobile phone to the measurement data (Measurement Report, hereinafter referred to as MRR) of peripheral cell, and in conjunction with the switching times of minizone, is assessed the need of increase or deletes adjacent area.
As shown in Figure 1, in NOX method, adjacent area deletion flow process is: when switching number of attempt and being less than a threshold value Rmv, added " deletion Neighboring Cell List " this adjacent area.When total BCCH measurement frequency list (BCCH Allocation List, hereinafter referred to as BA table) length is long, the cell neighboring relation in this list is deleted successively.
As shown in Figure 2, the flow process increasing adjacent area in NOX method is: when the measurement community relative signal intensity in MRR report is greater than a certain thresholding, added " increasing adjacent area candidate list ".When the BA of Target cell and this community show length all within allowed band time, then increase this to adjacent area; When Target cell or this community BA table exceed the length of maximum permission, then do not increase this to adjacent area.
The NOX neighbor cell optimizing method of Ericsson, although considered the factors such as the MRR measurement data that in the switching of minizone, community, mobile phone reports, has also had the following disadvantages:
When deleting adjacent area, the factor that NOX method is considered is too unilateral, just according to the switching number of attempt of statistics, for switching the low adjacent area of number of attempt, and will be deleted.And in actual conditions, if there is such user behavior event to occur, although probability is lower, as long as occur to attempt the switching of Target cell, very likely cause call drop because of changeable without adjacent area.So there is the risk of deleting adjacent area in NOX by mistake.
When increasing adjacent area, NOX method considers merely the relative signal intensity of MRR.For present GSM network, quite perfect owing to covering, mobile phone often can receive the community of a large amount of strong signal.Particularly city, signal at least can receive twenty or thirty higher than the frequency of-70dBm.Like this to the community in core city, the adjacent area of a large amount of candidate just must be had to increase.NOX determines merely the neighboring BS relationship increased from signal relative intensity, the phenomenon of " jump " definition adjacent area will inevitably be there is, namely community far away is defined as adjacent area, although and geographically on the contrary may be strong but strong not as community, a distant place and adjacent area could not be defined as due to signal near the community of oneself, cause " area covered ", increase the cover jamming to other communities.
When considering that BA shows length, due to each separate searches adjacent area, community candidate cell in NOX method, can there is the good community of relative signal, due to assessment in evening, BA table is long and can not become adjacent area, and the community of suboptimum is due to early assessment, BA table temporarily also has position and is defined as adjacent area.Such as: certain is very strong to the relative signal of community A and B, A → B, and the relative signal of B → A is very weak.But because B first assesses A, then because A → B is very strong, and the BA of A/B table does not all also reach maximum length, so A/B is defined as two-way adjacent area; But because B → A is very weak, A also had more excellent C originally as adjacent area, but exceed maximum length due to now BA table, and the adjacent area that C is A can not be defined as.

Embodiment
For making the technical problem to be solved in the present invention, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 3, be the flow chart of the neighbor cell optimizing method of an embodiment of the present invention, this neighbor cell optimizing method comprises:
Step S101: obtain the candidate adjacent of Target cell and existing adjacent area;
Step S102: priority is determined according to the distance of Target cell, antenna relative bearing and measurement report data MRR in described candidate adjacent and existing adjacent area;
Step S103: export the current adjacent area collection in Target cell according to the priority determined.
Candidate adjacent and existing adjacent area foundation carry out adding and deleting adjacent area with the mode of Target cell priority level by the present invention, and with measurement report, geographical position, antenna directional angle, switching statistics various dimensions assessment cell association, cell preference that is comparatively near, direction air exercise of adjusting the distance adds adjacent area, and conservative control adjacent area is added.
In step S101, the existing adjacent area of Target cell refers to the adjacent area in Target cell BA table, is the adjacent area as Target cell preset.The candidate adjacent of Target cell refers to the adjacent area that Target cell can search, and this candidate adjacent possible be increased in the BA table of Target cell.This step be obtain BA table in adjacent area and candidate adjacent, not to obtain adjacent area carry out additions and deletions process.
In step S102, by the priority that the multiple adjacent areas obtained are determined between Target cell, specifically determine priority according to the distance of Target cell, antenna relative bearing and measurement report data MRR, comprising:
Step S1021: using Target cell as cell-of-origin, the first priority is determined according to the distance of Target cell, antenna relative bearing and measurement report data MRR in described candidate adjacent and existing adjacent area;
Step S1022: using candidate adjacent and existing adjacent area as cell-of-origin, the distance of described Target cell and cell-of-origin, antenna relative bearing and measurement report data MRR determine the second priority.
When the present invention determines the priority of adjacent area and the Target cell obtained, during using Target cell as cell-of-origin, the adjacent area obtained and the distance of Target cell, antenna relative bearing and measurement report data MRR determine the first priority, simultaneously also using each obtain adjacent area as cell-of-origin, the distance of Target cell and cell-of-origin, antenna relative bearing and measurement report data MRR determine the second priority, consider two priority.Due to community between, Target cell may be there is very strong to the signal of adjacent area, but adjacent area is to the not strong situation of the signal of Target cell.Such as, certain is very strong to the relative signal of community A and B, A → B, but the relative signal that may there is B → A is very weak, need to consider for this reason simultaneously community between mutual signal strength signal intensity.
Step S103, the current adjacent area collection in Target cell determines according to the priority between Target cell and the adjacent area of acquisition, because the present invention has considered the priority of searching neighboring area and existing adjacent area and Target cell, the current neighbor of Target cell is determined according to priority, an Integrated comparative can be carried out to each adjacent area obtained, after avoiding directly determining adjacent area, BA express maximum length there is again the adjacent area that new signal is stronger and cannot continue add problem.When the priority of foundation has the first priority and the second priority, current neighbor of the present invention collection considers according to two priority, to determine the current neighbor collection of Target cell.
Distance between community of the present invention be according to distance between the base stations determine, utilize community calculation of longitude & latitude cell site spacing.Because earth on terrestrial equator takes a round totally 40075.04 kilometers for one week, and a circle is divided into 360 degree, the length=40075.04km/360=111.31955km often once gone up under the line.Longitude and latitude are the angle in the earth and the first meridian, equator respectively.Spherical formula can be utilized to calculate the distance of point-to-point transmission on sphere.Assuming that the longitude and latitude of Liang Ge community A/B is respectively (λ A, Φ A and λ B, Φ B), as shown in Figure 4, then the distance computing formula of community A/B is d=111.31955cos{1/ [sin Φ Asin Φ B ten cos Φ Acos Φ Bcos (λ B-λ A)] }.
Between community of the present invention, deflection determines being beaten or fighting each other between community, and for equidistant community, antenna directional angle air exercise or beaten, affects very large on covering.Due to bad to shielding properties after some antennas, cause backward lobe power comparatively strong, affect cell signal dorsad.
The present invention is when calculated direction angle air exercise relation, adopt rotational coordinates method, latitude and longitude of base station is considered as plane coordinate system coordinate (being similar to the earth when station spacing is shorter is a plane), coordinate system rotation is become with A (X1, Y1) B (X2, Y2) line is the X-axis of new coordinate, is rotated counterclockwise 90 degree of Y-axis as new coordinate, as shown in Figure 5 simultaneously.In new coordinate system, A/B Liang Ge community is in same level, is convenient to analyze air exercise relation.In new coordinate system, if in A/B Liang Ge community, have at least azimuth, a community towards another community ± 60 ° within the scope of, and the other side community deflection is within the scope of this community ± 90 °, be considered as two communities for air exercise community, otherwise be Bei Da community, as shown in Figure 6.
The priority between Target cell is determined in the multiple adjacent areas obtained by the present invention, and priority can divide as required, and the present embodiment is that just priority of adjacent domain divides 6 grades:
0 grade: community and adjacent area neighbouring relations are " defined ", and the countless certificate of nearby region measurement (cannot find the community that BCCH & BSIC is corresponding, or and measurement report MRR quantity <200, or measure absolute level <-90dBm), or station spacing is 0.
1 grade: station spacing <1KM, and measurement report MRR quantity >=200, measure absolute level >=-90dBm.
2 grades: station spacing >=1KM, and <5KM, fight each other in azimuth, measurement report MRR quantity >=200, measures absolute level >=-90dBm.
3 grades: station spacing >=5KM, and <10KM, fight each other in azimuth, measurement report MRR quantity >=200, measures absolute level >=-90dBm.
4 grades: station spacing >=1KM, and <5KM, the azimuth back of the body is beaten, and measurement report MRR quantity >=200 measures absolute level >=-90dBm.
5 grades: station spacing >=10KM, or station spacing >=5KM and azimuth the back of the body beat, measurement report MRR quantity >=200, measurement absolute level >=-90dBm.
Be " undefined " for community and adjacent area neighbouring relations, and adjacent area is empty (cannot find the community that BCCH & BSIC is corresponding, or and measurement report MRR quantity <200, or measure absolute level <-90dBm), remove this part community.
When adjacent cell has equal priority, the weighted value according to the average level of adjacent cell carrys out Further Division priority.According to measurement report data, calculate the average level weighted value " NAVSS weighted value " of each measurement community.Average level weighted value on average reports level NAVSSi and occurrence number TIMESi according to each report Zhong Gai community, and the relation being in the last the i-th in report calculates: NAVSS weighted value=(NAVSS1*TIMES1*6+NAVSS2*TIMES2*5+NAVSS3*TIMES3*4+NAVSS4*T IMES4*3+NAVSS5*TIMES5*2+NAVSS6*TIMES6)/(TIMES1*6+TIMES2*5+TIMES3*4+TIMES4*3+TIMES5*2+TIMES6).
According to priority of adjacent domain division result, from priority 0, each rank, according to the electrical level weighting value size of measuring-signal, sorts successively.Come the community pair before BA expresses maximum, be the Neighboring Cell List of output.For not in the defined adjacent area exporting Neighboring Cell List, be and delete adjacent area; For the undefined adjacent area in output listing, be newly-increased adjacent area.
Also arrange after the community that the present invention obtains, to remove the less community of correlation, thus reduce operand.This part comprise arrange measurement report data, delete adopt the few adjacent area of point to, increase must add Neighboring Cell List, remove forbid adding Neighboring Cell List, switch and attempt very few Neighboring Cell List.The time span that measurement report and switching statistics are got can customize, and the whole network 7*24 hour data is got in suggestion.
As shown in Figure 7, be the arrangement basic data flow chart of an embodiment of the present invention, first remove ban is defined as the community of adjacent area, as part indoor cell, un-activation community etc.; Next removes and switches the few community of number of attempt, and switching number of attempt thresholding minHO can be self-defined, and suggestion is set to 10 times; Remove the community that measurement report quantity is few again, measurement report sample thresholding minTimes can customize, and suggestion is 10000 times; Then start measurement report data of decoding, mate the geographically nearest cell name identical with measurement report BCCH/BSIC.If nearest community distance is greater than distance threshold maxDistance, then think illegal community, also can be removed.
The present invention exports the adjacent area that the current adjacent cell in Target cell concentrates and comprises the community belonging to same frequency range with Target cell or the community not belonging to same frequency range, can also both have.Part such as can be selected to be the community of same frequency range, and part is the community of alien frequencies section.Be described in detail below in conjunction with specific embodiment:

After also initialization completes " rule table " to structure, start loop iteration.As shown in Figure 8, each loop iteration is all the renewal to " rule table ", and adds up iterations.After a loop iteration, " rule table " does not upgrade, and represent all neighboring BS relationship and all meet pre-defined rule, then iteration terminates.Ji Shi homogeneous-frequency adjacent-domain, the community relation list that " being added to homogeneous-frequency adjacent-domain " in " rule table " is Y.
For the rule table correction in each loop iteration process, adopt the correction flow process as Fig. 8.Concrete modification rule is:
" rank of forward NAVSS " of first pair of adjacent area of each community is 1, and " reverse NAVSS rank " is drawn by " rank of forward NAVSS " that reverse neighboring BS relationship is corresponding.The forward rank of such as adjacent area B → A is 8, then the reverse rank of A → B is 8.Right " rank of forward NAVSS " in the 2nd pair of adjacent area that adjacent area is later arranges rule and is:
If lastrow record " being added to homogeneous-frequency adjacent-domain " is Y, then " rank of forward NAVSS " of this line item " rank of forward NAVSS "+1 that be lastrow record;
If lastrow record " being added to homogeneous-frequency adjacent-domain " is N, then " rank of forward NAVSS " of this line item be lastrow record " rank of forward NAVSS ".
" reverse NAVSS rank " successively right from reverse adjacent area " rank of forward NAVSS " is searched and is drawn.
" be added to homogeneous-frequency adjacent-domain " for Y must meet following condition simultaneously:
Belonging to cell-of-origin and adjacent cell, frequency range is identical;
" rank of forward NAVSS " <=10;
" rank of reverse NAVSS " <=10.
2. the rule of adding alien frequencies adjacent area is basically identical with the rule of adding homogeneous-frequency adjacent-domain, and different places has:
Alien frequencies adjacent area only adds 5;
" homogeneous-frequency adjacent-domain is added to " for Y must meet following condition simultaneously: belonging to (A) cell-of-origin and adjacent cell, frequency range is different in " rule table "; (B) " rank of forward NAVSS " <=5; (C) " rank of reverse NAVSS " <=5.
3. add residue adjacent area
After having added 10 homogeneous-frequency adjacent-domains, 5 alien frequencies adjacent areas, if BA table length is vacant in addition, then remaining planned number is added according to the mode of above-mentioned interpolation with frequency, alien frequencies adjacent area.Unlike, do not consider whether same alien frequencies frequently here, carry out rank according to priority of adjacent domain, NAVSS weighted value completely, forward preferential increase, until BA expresses length limit.
