Embodiment
Specifically describe the preferred embodiments of the present invention below in conjunction with accompanying drawing, wherein, accompanying drawing constitutes the application's part, and is used to explain principle of the present invention with embodiments of the invention.For clear and simplification purpose, when it possibly make theme of the present invention smudgy, with specifying in detail of known function and structure in the omission device described herein.
At first, be elaborated in conjunction with 1 pair of said method of the embodiment of the invention of accompanying drawing.
As shown in Figure 1, Fig. 1 is the schematic flow sheet of the said method of the embodiment of the invention, specifically can comprise the steps:
Step 101: according to the switch data collection of main plot A, confirm the collection S of matched adjacent zone and the miss-configured neighboring cells collection X of main plot, and calculate existing matched adjacent zone number m among the matched adjacent zone collection S;
Step 102: add up this main plot A and arrive each switching times and the switching times of this main plot of matched adjacent zone, therefrom find the peak of switching times, be designated as MAX to each miss-configured neighboring cells; Wherein, the main plot to certain the switching times of matched adjacent zone comprise the summation of actual switching times and virtual switching times, possibly virtual switching times be zero also, promptly only comprise actual switching times; The main plot to the switching times of certain miss-configured neighboring cells possibly comprise border switching times and virtual switching times with, possibly actual switching times be zero also, promptly comprise virtual switching times;
Need to prove; The sub-district that does not have true switching times for having only virtual switching times; The switch data that reports is concentrated does not have the sub-district id information; This just need find the sub-district according to its scrambler, if can not find corresponding district, then is thought of as interference signal and does not handle as miss-configured neighboring cells;
Step 103: the peak MAX according to switching times calculates adjacent area increase thresholding Threshold_Add and adjacent area deletion thresholding Threshold_Delete respectively, wherein,
Increase thresholding Threshold_Add=MAX*a%;
Deletion thresholding Threshold_Delete=MAX*d%; Threshold_Add and Threshold_Delete are dynamic thresholds, and wherein, parameter a is first parameter value that presets; D is second parameter value that presets; The value user of a and d can carry out oneself definition according to the network actual conditions, and the span of general a is 0.5～2, and the span of d is 6～15;
Step 104: in the collection X of miss-configured neighboring cells, find all miss-configured neighboring cells of virtual switching times＞Threshold_Add and be increased to and intend among the newly-increased adjacent area collection Z, calculate these simultaneously and intend newly-increased miss-configured neighboring cells number n;
Step 105: all that in matched adjacent zone collection S, find virtual switching times＜Threshold_Delete have been joined the sub-district and have been increased to and intended among the deletion adjacent area collection D, calculate the number of the matched adjacent zone k that these intend deletion simultaneously;
Step 106: finally confirm the additions and deletions of adjacent area according to predetermined adjacent area additions and deletions principle; Promptly judge the adjacent area whether (adjacent area concentrate existing adjacent area number m+ intend the adjacent area number k that newly-increased adjacent area number n-intends deletion) is less than or equal to regulation limit the number (for example 31); If be less than or equal to; Then execution in step 107, otherwise execution in step 108;
Step 107: the adjacent area that (existing matched adjacent zone number m+ intends the number of the matched adjacent zone k that newly-increased miss-configured neighboring cells number n-intends deletion) is less than or equal to regulation limits the number, and then provides the user and all are intended newly-increased miss-configured neighboring cells all is increased to the suggestion among the matched adjacent zone collection S;
Step 108: (existing matched adjacent zone number m+ intends the number of the matched adjacent zone k that newly-increased miss-configured neighboring cells number n-intends deletion) is greater than predetermined adjacent area restricting data; That matched adjacent zone that needs to intend deletion is from removing the matched adjacent zone collection S, with matched adjacent zone concentrate remaining all matched adjacent zone with intend the miss-configured neighboring cells that increase newly and sort according to switching times; For intending newly-increased miss-configured neighboring cells:, otherwise do not join among the matched adjacent zone collection S if ordering preceding 31, joins matched adjacent zone as the adjacent area that increases newly and concentrates; For existing matched adjacent zone: if ordering preceding 31, continues to be retained among the matched adjacent zone collection S, preceding 31, then provide the suggestion of user with its deletion if fall;
Step 109: the matched adjacent zone that will intend whole plan deletions of deletion adjacent area collection D is deleted.
For the ease of understanding the present invention, below will further specify with a concrete example.
1) like following table one; Switch data collection according to main plot A; Can confirm the adjacent area collection S (S1 is matched adjacent zone to S31) of A; Existing adjacent area number m among the NEIGHBOR SET S is 31, and miss-configured neighboring cells collection X (X1 is miss-configured neighboring cells to X7) is so be not counted in miss-configured neighboring cells collection X because scrambler is 77 the sub-district that in database, do not match.
Table one:
2) in the switching times of the switching times of each adjacent area and A each adjacent area in the X, find the peak of switching times in from A to S, be designated as MAX (A-X);
For example: MAX in the table one (A-X)=1786.
3) calculating the adjacent area respectively according to MAX (A-X) increases thresholding Threshold_Add and adjacent area deletion thresholding Threshold_Delete, wherein,
Increase thresholding: Threshold_Add=MAX (A-X) * a%;
Deletion thresholding: Threshold_Delete=MAX (A-X) * d%,
Here, if the parameter value that is provided with is a=10 and d=1; Then
Increase thresholding: Threshold_Add=MAX (A-X) * 10%=178.6;
Deletion thresholding: Threshold_Delete=MAX (A-X) * 1%=17.86,
4) in the collection X of miss-configured neighboring cells, find virtual switching times greater than all sub-districts that increase thresholding Threshold_Add and join and intend among the newly-increased adjacent area collection Z, calculate its number n simultaneously, these sub-districts are as intending newly-increased adjacent area;
Here, can confirm to intend newly-increased adjacent area is X1, X2, and X3, X4, X5 intends increase adjacent area number n=5;
5) in matched adjacent zone collection S, find switching times less than all sub-districts of deletion thresholding Threshold_Delete and join and intend among the deletion adjacent area collection D, calculate its number k simultaneously, these sub-districts are as intending the deletion adjacent area;
Here, confirmable plan deletion adjacent area is S29, S30, and S31 intends deletion adjacent area number k=3;
6) calculating " the newly-increased adjacent area of existing matched adjacent zone number+plans number-plans deleted the adjacent area number " is the value of m+n-k, judges that it is whether above adjacent area limit the number (for example 32):
If m+n-k≤31 then all provide the suggestion of newly-increased adjacent area with the newly-increased adjacent area of the plan among all adjacent area collection Z;
If m+n-k＞31; Then remove the adjacent area collection D that will delete among the collection S of adjacent area; Sort their switching times (switching times+virtual switching times) with the adjacent area of intending among the newly-increased adjacent area collection Z together in all remaining adjacent areas; Ordering provides the suggestion of newly-increased adjacent area among the set Z in preceding 31 adjacent area; Ordering keeps as the adjacent area in preceding 31 adjacent area in the S set, and ordering provides the suggestion of deletion adjacent area 31 later adjacent areas;
Here, m+n-k=31+5-3=33
Because 33 greater than 32, therefore need be with sub-district S1～S28 and X1, X2, X3, X4, the switching times of X5 sorts, because S27 and S28 come at last, therefore need S27 and S28 be provided the suggestion of deletion adjacent area.
7) intend the adjacent area of deleting among all adjacent area collection D and all provide the deletion suggestion.
Need to prove that the adjacent area increases thresholding and adjacent area deletion thresholding only plays partial action, also having a very important restriction is exactly to guarantee that adjacent area quantity all the time can not be above 31.
The result who obtains at last is shown in table two:
Next combine 2 pairs of said devices of the embodiment of the invention of accompanying drawing to be elaborated.
