Description
Technical field
The present invention relates to wireless communication technology, relate in particular to the method and apparatus of a kind of telephone traffic Pre-Evaluation and the newly-built base station carrier configuration in the wireless communication technology.
Background technology
Along with the reduction of the abundant and rate of radio communication service kind, user's wireless communication needs increases fast in recent years.In this case; Only depend on the bearing capacity that has the base station can not satisfy user's demand far away; Promote network carrying ability through newly-built macrocell base stations and become the main means that cordless communication network is built; But newly-built how many carrier frequency of macrocellular configuration could both satisfy the customer service demand after opening guarantees user's perception, can make utilization rate of equipment and installations arrive the service efficiency that a reasonable level guarantees resource again, then need confirm through newly-built station telephone traffic assessment.
At present, it is following to carry out the method for newly-built station telephone traffic assessment:
The regulation portable terminal needs to comprise the wireless signal strength that portable terminal receives in the measurement report regularly to the base station reporting measurement reports in the GSM standard.Behind radio transmission model and relevant wireless parameter, certain is put the distance of base station and between the base station radio signal strength signal intensity that this point receives, can derive each other.According to this principle; Behind a newly-built macrocell base stations and the sub-district confirming to be adjacent; Two signal of base station intensity that a bit receive arbitrarily in the overlay region of newly-built base station cell and its neighbor cell can both be calculated; Relatively after the intensity of the two, can judge that through certain rule the telephone traffic of this point is to be absorbed or absorbed by former base station by newly-built base station.
In application number was 200710135017.8 Chinese patent, a kind of newly-built macrocellular telephone traffic Pre-Evaluation method based on above-mentioned principle was disclosed:
At first for each new site according to choose the adjacent base station of candidate apart from distance, then according to the adjacent base station of final definite newly-built base stations such as the distance of candidate base station and newly-built station, angle; Whether pass through the neighbor cell that cell range is confirmed newly-built base station cell through the line between adjacent base station and the newly-built base station again; Then through relatively confirming the ownership of the traffic of this point in certain signal strength signal intensity of putting the neighbor cell of base station existing, newly-built sub-district with it.
The method of wherein confirming neighbor cell is:
With the difference of distance between any two adjacent base stations and the newly-built base station than last distance between them, if this distance satisfies the adjacent base station that certain relation just is judged as newly-built base station less than given adjacent nuisance parameter and angle.That is, establish base station sequence (B1 ... Bm) satisfy condition | B1B0| | B2B0| ... | BmB0|, ((i＞j) is the base station in the sequence for 1≤j≤m), Bi to establish Bj; And ∠ Bj B0 Bi>if 90 ° of Bi for any Bj, total satisfy (| BiB0|-|BjB0|)/| BiBj|≤d (0 < d < 1), then Bi is judged as the switching adjacent base station; D is adjacent nuisance parameter, and the more little Bj of d is also more little to the influence of the switching between B0 and Bi, and condition is also harsh more; The adjacent base station quantity that obtains is also just few more; Like this, just can revise the adjacent base station set of selecting through the value of adjustment d, general d gets between 0.6 ~ 0.8.
In said method, the quantity of choosing candidate base station does not have the algorithm of science to confirm, is that the people chooses, and omits easily; When confirming final adjacent base station, adjacent nuisance parameter d also is the artificial numerical value of confirming, is easy to because the improper result of calculation that causes of value is unreasonable.
The method of calculating newly-built base station call absorption in the above-mentioned patent application does; Select a bit; Confirm that base station A arrives the signal strength signal intensity of this point and the signal strength signal intensity that base station B arrives this point, compares the back with the two then and judges that telephone traffic of this point is still absorbed by base station B by base station A.
But obtaining the identical point of base station B signal strength signal intensity has a plurality of; These points are not all to be absorbed by base station A, and during the statistics telephone traffic, measurement report can only count the shared ratio of telephone traffic of certain certain signal strength signal intensity of base station and can not count the physical points that traffic distributes under the same signal intensity situation; That is to say; Though can calculate the point that base station A absorbs telephone traffic, can not calculate the telephone traffic that is absorbed by base station A what are, and artificial estimation be easy to occur deviation.

Embodiment
The overlay area of base station can be divided into a plurality of sub-districts according to the antenna for base station number; The sub-district traverse line of each sub-district is defined as the direction of antenna in cell; All there are several neighbor cells each sub-district, and neighbor cell can be that the sub-district of same base station also can be the sub-district of adjacent base station.For newly-built sub-district, when calculating the telephone traffic that newly-built sub-district absorbs neighbor cell, do not consider the neighbouring relations between the newly-built sub-district, only consider the neighbor cell of non-newly-built adjacent base station.Each newly-built sub-district to newly-built base station; Calculate the telephone traffic that this newly-built sub-district should absorb from the neighbor cell all sub-districts of adjacent base station respectively, obtain the telephone traffic that newly-built base station should absorb from other adjacent base stations after the telephone traffic addition that again all newly-built sub-districts is absorbed from neighbor cell.
Therefore, when the newly-built base station call amount of assessment, at first to confirm the adjacent base station of this newly-built base station, and in all sub-districts of adjacent base station, confirm the neighbor cell of each sub-district of newly-built base station respectively; Last again to each newly-built sub-district of newly-built base station, calculating this newly-built sub-district respectively should be from the telephone traffic of the absorption of the neighbor cell all sub-districts of adjacent base station.
Definite method of adjacent base station is a lot; The people who for example uses in the background technology to be mentioned is the method for choosing; For confirming the adjacent base station of newly-built base station more accurately; The present invention provides a kind of method of utilizing Thiessen polygon to confirm the adjacent base station of newly-built base station, and Thiessen polygon proposes when Dutch climatologist AHThiessen calculates average rainfall according to the rainfall of the weather station of discrete distribution first, and is concrete: that all adjacent weather stations are linked to be triangle; Make the perpendicular bisector on these each limits of triangle; So the some perpendicular bisectors around each weather station just surround a polygon, promptly Thiessen polygon is represented the rainfall intensity in this polygonal region with the rainfall intensity of a unique weather station that is comprised in this polygon.The characteristic of Thiessen polygon is: 1, only contain a discrete points data in each Thiessen polygon; 2, the point in the Thiessen polygon arrives the nearest of corresponding discrete point; 3, the point that is positioned on the Thiessen polygon limit is equal to the distance of the discrete point on its both sides.Thiessen polygon can be used for qualitative analysis, statistical analysis, contiguous analysis etc.The character in Thiessen polygon zone for example, can be described with the character of discrete point; The data of available discrete point are calculated the data in Thiessen polygon zone; Judge when a discrete point is adjacent with other which discrete point, can directly draw according to Thiessen polygon, if it is Thiessen polygon is a n limit shape, then just adjacent with n discrete point; When a certain data point fell into a certain Thiessen polygon, it was the most contiguous with corresponding discrete point, need not computed range.
In embodiments of the present invention; Confirm the adjacent base station of newly-built base station through the method for Thiessen polygon; Newly-built station and non-newly-built base station are marked on the map according to longitude and latitude, and non-newly-built base station is when the newly-built base station of planning, the existing base station in this zone; In the scope of map, do the Thiessen polygon of all base stations, comprise newly-built base station and non-newly-built base station.For any newly-built base station, the base station in the Thiessen polygon adjacent with the Thiessen polygon at its place all is the adjacent base station of this newly-built base station, and is as shown in Figure 1: the base station among Fig. 1 in the dash area all is the adjacent base station of the base station in the middle white part.
Need to prove; Because newly-built base station does not have in esse telephone traffic; So the base station in the Thiessen polygon adjacent with the Thiessen polygon at place, newly-built base station is if newly-built base station; Then do not set up the relation of adjacent base station between two newly-built base stations, promptly a newly-built base station can not be as the adjacent base station of another newly-built base station.
Further, be the neighbor cell of accurate definite newly-built base station cell, can utilize the sub-district deflection to confirm neighbor cell:
All there is traverse line each sub-district; Shown in Fig. 2 a; Confirm the sub-district traverse line of newly-built base station cell and the sub-district traverse line of neighbor cell; And the line between newly-built base station cell base station and the neighbor cell base station, can confirm the sub-district traverse line of newly-built base station cell and angle a and the sub-district traverse line of adjacent base station sub-district and the angle b of newly-built base station and adjacent base station line line segment of newly-built base station and adjacent base station line line segment; Be not more than 180 when spending when the angle of two sub-district traverse lines and two base station lines with a+b; Confirm that the adjacent base station sub-district is the neighbor cell of newly-built base station cell, and this angle and a+b are more little, the tightness degree of newly-built base station cell and its neighbor cell is big more.In general, tightness is big more, and the telephone traffic that newly-built sub-district should absorb from neighbor cell is many more, that is to say that angle and a+b are more little, and the telephone traffic that newly-built sub-district can absorb from neighbor cell is many more.
Shown in Fig. 2 a; When the sub-district of the sub-district of newly-built base station cell traverse line and neighbor cell traverse line in the base station during line homonymy; An angle adopts and calculates angle clockwise, and another angle adopts and calculates angle counterclockwise, and the angle of the sub-district traverse line of newly-built base station cell and newly-built base station and adjacent base station line line segment is a; With the sub-district traverse line of adjacent base station sub-district and the angle of newly-built base station and adjacent base station line line segment be b, the angle of two sub-district traverse lines and two base station lines and be a+b;
Shown in Fig. 2 b; When the sub-district of the sub-district of newly-built base station cell traverse line and neighbor cell traverse line in the base station during line homonymy; If the angle that the sub-district traverse line of newly-built base station cell and newly-built base station and adjacent base station line line segment are got is the supplementary angle of angle a; The angle that the sub-district traverse line of while adjacent base station sub-district and newly-built base station and adjacent base station line line segment are got is the supplementary angle of angle b; When then calculating, the angle of two sub-district traverse lines and two base station lines and be 360-(360-a)+[360-(360-b)]=720-[(360-a)+(360-b)]=a+b;
Shown in Fig. 2 c; When the sub-district of the sub-district of newly-built base station cell traverse line and neighbor cell traverse line in the base station during line heteropleural; Two angles all adopt clockwise calculating angle; The angle of the sub-district traverse line of newly-built base station cell and newly-built base station and adjacent base station line line segment is that the sub-district traverse line of a and adjacent base station sub-district and the angle of newly-built base station and adjacent base station line line segment are b, the angle of two sub-district traverse lines and two base station lines and be a+b;
Shown in Fig. 2 d; When the sub-district of the sub-district of newly-built base station cell traverse line and neighbor cell traverse line in the base station during line heteropleural; If the angle that the sub-district traverse line of newly-built base station cell and newly-built base station and adjacent base station line line segment are got is the supplementary angle of angle a; The angle that the sub-district traverse line of while adjacent base station sub-district and newly-built base station and adjacent base station line line segment are got is the supplementary angle of angle b; When then calculating, the angle of two sub-district traverse lines and two base station lines and be 360-(360-a)+[360-(360-b)]=720-[(360-a)+(360-b)]=a+b.
In sum, the angle between sub-district traverse line and the base station line is two angles that are less than or equal to 180 degree that line became.
The telephone traffic that can absorb from neighbor cell at most for the newly-built base station cell of clear statement; The embodiment of the invention has defined angle traffic coefficient; Angle traffic coefficient is that the field intensity value in newly-built base station is when being higher than the field intensity value of non-newly-built base station; Newly-built sub-district A can absorb the ratio of the telephone traffic of neighbor cell B; This ratio value can represent that according to aforementioned theory analysis, the telephone traffic that can absorb neighbor cell B owing to newly-built sub-district A at most is relevant with a+b with aforesaid angle through portable terminal divided by total amount of switched of one of them sub-district and its all neighbor cells in the number of handovers of two minizones; Then this ratio also should be relevant with a+b, therefore is called angle traffic coefficient.A+b is more little, and angle traffic coefficient should be big more, and the result of statistics and emulation has proved above-mentioned analysis, the approximate inversely prroportional relationship that is of angle traffic coefficient and a+b.
When two sub-districts have the cell relation of facing; Usually angle traffic coefficient can be summarized as: m+ (1-m) (180-a-b)/180, wherein m is the statistical value of a+b=180 angle traffic coefficient when spending, and is relevant with the number of cells that the base station is divided usually; When a+b is 180 when spending; Can to draw angle traffic coefficient be m through calculating, and when a+b is 0 when spending, can to draw angle traffic coefficient be 1 through calculating.
Below with base station, three cracks; Be each base station be divided into 3 sub-districts situation for example; Utilize statistics under the different situations confirm between a newly-built sub-district and the one of which neighbor cell angle traffic coefficient and angle and the relation between the a+b; And provide angle and the method for calculating angle traffic coefficient utilized, and wherein p1 identifies angle traffic coefficient, and c is angle and a+b:
When the sub-district traverse line of the sub-district traverse line of a sub-district of newly-built base station and its neighbor cell during at two base station line homonymies, the relation between angle traffic coefficient p1 and the c is shown in Fig. 3 a, and wherein transverse axis is angle and c; The longitudinal axis is angle traffic coefficient p1, among the figure, when c=180 spends; P1 is 0.09, and when c=0 spent, p1 was 1; And the straight line from figure can significantly be found out inversely prroportional relationship, and figure cathetus corresponding formula is:
p1=m+（1-m）*（180-c）/180
When the number of cells of wherein dividing when existing base station is 3; M=0.09 is two sub-district angles and c=180 when spending, and the newly-built base station cell that counts can absorb the telephone traffic ratio of neighbor cell; In practical operation; M in the formula can be according to the corresponding adjustment of actual count value, and when the number of cells of especially dividing when the base station was not 3, the m in the formula need adjust accordingly according to the actual count value;
When two sub-district traverse lines during at two base station line heteropleurals; The relation of angle traffic coefficient p1 and c is shown in Fig. 3 b, and when c=180 spent, angle traffic coefficient was 0; When c=0 spends; Angle traffic coefficient is 1, and from figure curve can significantly find out inversely prroportional relationship, the curve corresponding formula is among the figure:
p1=n+（1-n）*（180-c）/180
When the number of cells of wherein dividing when existing base station was 3, n=0 was two sub-district angles and c=180 when spending, and the newly-built base station cell that counts can absorb the telephone traffic ratio of neighbor cell; In practical operation, when the number of cells of especially dividing when the base station is not 3, can be according to statistical value and the curve of making; The adjustment formula, according to the statistics of reality, n wherein also can be negative value; Computational methods are n=1-180/c ', wherein c ' for p1 equal 0 o'clock corresponding minimum angles with, at c during more than or equal to c '; P1 is 0, and during less than c ', p1 and c have inversely prroportional relationship at c.
