For reasonable speed adjust strategy.
It elaborates with reference to the accompanying drawing to the preferred embodiment of the invention.
As shown in fig.1, to the cell in similar set of cells, generating corresponding speed adjust in the embodiment of the present invention
Strategy, specific steps are as follows:
Step 100: respectively according to the service feature of each cell, rate stamps being carried out to respective cell, wherein rate
Label is for characterizing rate feature of the cell based on current business feature.
Specifically, rate stamps, method are carried out to each cell respectively are as follows:
1) it selectes a cell and this cell is counted in some time granularity according to the service feature in this cell
Rate relevant parameter, wherein in rate relevant parameter include peak rate, Mean Speed and intermediate value rate, intermediate value rate
It is that resulting rate feature, specific formula for calculation are calculated based on peak rate and Mean Speed are as follows:
Vmaxc=Σi(ki*pi*qi*Vmaxi/(Σipi*ΣiQi)) formula [1]
Vavgc=Σi(ki*pi*qi*Vavgi/(Σipi*ΣiQi)) formula [2]
Vprc=L1*Vmaxc-L2*VavgcFormula [3]
Wherein, VmaxcIndicate peak rate of the cell in some time granularity, VavgcIndicate the cell in some time
Mean Speed in granularity, VprcIt indicates according to the resulting speed of peak rate and Mean Speed and the weight calculation of both
Rate characteristic value, pi are the initiation number of certain a kind of business in the cell, and qi is the flow of such business in the cell, and ki is that this is small
The weight of such business in area, i.e. significance level of such business in the cell in all business, VmaxiTo be somebody's turn to do in the cell
The peak rate of business, VavgiFor the Mean Speed of such business in the cell, L1 and L2 are respectively the cell in some time
Both the weight of peak rate and Mean Speed in granularity, i.e., specific gravity shared in entire rate feature respectively, certainly, L1
It can be obtained based on experience value with the value of L2, and optimization can be updated at any time.
By formula [1], the service feature of all business in the cell can be integrated, calculates the cell in some time grain
Peak rate in degree；By formula [2], the service feature of all business in the cell can be integrated, calculates the cell at certain
Mean Speed in a time granularity；By formula [3], the peak value in the cell in some time granularity can be comprehensively considered
The rate feature value an of centre is calculated in rate and Mean Speed.
2) peak rate is compared with default first thresholding, intermediate value rate and default second threshold value is compared
Compared with, wherein the first thresholding is greater than the second thresholding；
If the peak rate is greater than first thresholding, and the intermediate value rate is greater than second thresholding, then by phase
The cell answered is labeled as first kind rate cellular；
If the peak rate is greater than first thresholding, and the intermediate value rate is not more than second thresholding, then will
Corresponding cell is labeled as the second class rate cellular；
If the peak rate is not more than first thresholding, and the intermediate value rate is greater than second thresholding, then will
Corresponding cell is labeled as third class rate cellular；
If the peak rate is not more than first thresholding, and the intermediate value rate is not more than second thresholding, then
Corresponding cell is labeled as the 4th class rate cellular.
For example, the first thresholding of scheduled rate characteristic value (is denoted as VTHR1) and the second thresholding (be denoted as VTHR2), each is small
The peak rate V in areamaxcWith intermediate value rate VprcRespectively with VTHR1And VTHR2It compares, four class cells is generated according to comparison result,
Assuming that the rate stamps of first kind rate cellular to the 4th class rate cellular are respectively A, B, C, D, in which:
If Vmaxc>VTHR1, and Vprc>VTHR2, then the cell is labeled as A；
If Vmaxc>VTHR1, and Vprc≤VTHR2, then the cell is labeled as B；
If Vmaxc≤VTHR1, and Vprc>VTHR2, then the cell is labeled as C；
If Vmaxc≤VTHR1, and Vprc≤VTHR2, then the cell is labeled as D；
Step 110: according to the rate stamps of each cell and the adjacent critical parameter of minizone, by all cells into
Row region division generates multiple similar set of cells, wherein the rate stamps for the cell for including in each similar set of cells
It is identical.
Specifically, all cells are traversed, whenever the rate stamps for determining two cells are identical, and according to the adjacent of minizone
When critical parameter determines that the two cells are adjacent, the two cells are divided into the same similar set of cells, until all small
Area determines to finish, and generates multiple similar set of cells, wherein the adjacent critical parameter of minizone be minizone space length,
At least one of wireless signal covering and three parameters of moving characteristic of terminal.Often the sheet of cell continuously covered is gathered around
There are similar user group and similar user habit, therefore, according to service distribution similar (i.e. rate stamps are identical) and space
Neighbouring or have the cell of practical mobility signal or terminal interaction to be sorted out, the similar set of cells of generation possesses similar use
Family group and similar service distribution.
There are many kinds of the modes for specifically dividing similar set of cells, and two ways is introduced in citing below.
Mode one
To select the geographical location where cell for basic reference point, using the selected overlayable range of cell as radiation area
Domain generates a polygonal region, and each cell can generate the polygonal region that can represent its coverage area, often
The rate stamps of one polygonal region are the rate stamps of respective cell, wherein all polygonal regions form seamless
Connection, in this way, all cells can be seamless adjacent；
All cells are traversed, whenever the rate stamps for determining two polygonal regions are identical, and the two polygonal regions
When space is adjacent, the two polygonal regions are merged, form a similar area collection, i.e., similar set of cells repeats
This step generates multiple similar area collection, wherein each similar area is concentrated comprising more until the judgement of all cells finishes
A cell, and each cell is pertaining only to a similar area collection, the rate stamps of every two adjacent similar area collection are different.
Mode two
First determine whether two cells are adjacent, Rule of judgment can choose one of following condition or any group
It closes.
The distance between 1: two cell geographic location of condition is less than pre-determined distance threshold value；
2: one cells of condition another received cell signal level intensity be more than preset signal strength threshold value；
Condition 3: the switching of a cell to another cell occurs when being in connected state for terminal, alternatively, terminal is in sky
A cell occurs when not busy state to the gravity treatment between another cell.
If two cells meet at least one of three of the above Rule of judgment, it is possible to determine the two cells
It is adjacent.
Then, all cells are traversed, whenever the rate stamps for determining two cells are identical, and determine that the two cells are adjacent
When, the two cells are divided into the same similar set of cells, until the judgement of all cells finishes, generate multiple similar cells
Set, wherein include multiple cells in each similar set of cells, and each cell is pertaining only to a similar cell set
It closes, the rate stamps of every two adjacent similar set of cells are different.
Step 120: respectively according to the service feature for all cells for including in each similar set of cells, generating corresponding
Reference rate set, wherein reference rate set is for characterizing a speed of the similar set of cells based on current business feature
Rate feature.
For all similar set of cells of generation, corresponding reference rate collection is generated to each similar set of cells
It closes, specifically, respectively according to all Zone features for including in each similar set of cells, calculates separately each phase
Like the weighted average rate of set of cells, weighted median rate and weighting peak rate, generated according to the calculated result of acquisition
The reference rate set of each similar set of cells.
For example, weighted average rate indicates that weighted median rate is indicated with V2 with V1, weighting peak rate is indicated with V3,
Then specific formula for calculation are as follows:
V1=Σj(kj*pj*qj*Vavgj/(Σjpj*ΣjQj)) formula [4]
V2=Σj(kj*pj*qj*m*Vmaxj+n*Vavgj)/(m+n*Σjpj*ΣjQj) formula [5]
V3=Σj(kj*pj*qj*Vmaxj/(Σjpj*ΣjQj)) formula [6]
Wherein, pj is the initiation number of certain a kind of business in the similar set of cells, and qj is should in the similar set of cells
The flow of class business, kj are the weight of such business in the similar set of cells, i.e., such business is in the similar set of cells
Significance level in all business, VmaxjFor the peak rate of the business in the similar set of cells, VavgjFor the similar cell set
The Mean Speed of such business in closing, m and n are respectively the peak rate of the similar set of cells in some time granularity and put down
Both the weight of equal rate, i.e., specific gravity shared in entire rate feature respectively, certainly, the value of m and n can rule of thumb be worth
Out, and optimization can be updated at any time.
By formula [4], the service feature of all business in all cells in the similar set of cells can be integrated, is calculated
The Mean Speed of the similar set of cells in some time granularity；By formula [5], the similar cell set can be comprehensively considered
Peak rate and Mean Speed of all cells in some time granularity in closing, are calculated the rate feature of a centre
Value；By formula [6], the service feature of all business in all cells in the similar set of cells can be integrated, the phase is calculated
Like peak rate of the set of cells in some time granularity.
Step 130: the corresponding reference rate set of the similar set of cells according to belonging to cell generates phase for the cell
The speed adjust strategy answered.
Because possessing similar user group and similar service distribution in a similar set of cells, on this basis,
It is more accurate for the cell speed adjust strategy generated in similar set of cells by corresponding algorithm, it is more efficient.
Specifically, determine similar set of cells belonging to a cell, and determine the corresponding reference of the similar set of cells
Rate set, wherein include weighted average rate, weighted median rate in the corresponding reference rate set of the similar set of cells
And weighting peak rate；
First object rate is determined according to weighted average rate, and the second targeted rate, root are determined according to weighted median rate
Third targeted rate is determined according to weighting peak rate, wherein first object rate is less than the second targeted rate, and the second target is fast
Rate is less than third targeted rate, wherein targeted rate is used to indicate what the cell was adjusted in generating rate adjustable strategies
Foundation；
If the cell is first kind rate cellular, since the paroxysmal high-rate service ratio of first kind cell is higher, because
This takes fast lifting rate, the strategy of fast falling rate.It is, when meeting rate up-regulation condition, rate is direct
On be adjusted to third targeted rate, alternatively, meet rate lower condition when, by rate it is direct under be adjusted to first object rate；
If the cell is the second class rate cellular, since the second class cell duration high-rate service ratio is higher,
Take fast lifting rate, slowly reduce rate strategy, it is, meet rate up-regulation condition when, by rate it is direct on
Be adjusted to third targeted rate, alternatively, meet rate lower condition, and determine present rate be greater than the second targeted rate when, will
It is adjusted to the second targeted rate under rate, and when meeting downward condition next time, continues that first object speed will be adjusted under rate
Rate；
If the cell is third class rate cellular, since the sudden low rate traffic ratio of third class cell is higher,
It takes and slowly promotes rate, the strategy of fast falling rate, it is, meeting rate up-regulation condition, and determine present rate
When less than the second targeted rate, the second targeted rate will be adjusted in rate, and when meeting up-regulation condition next time, continue by
Third targeted rate is adjusted in rate, alternatively, first object rate will be adjusted under rate when meeting rate downward condition；
If the cell is the 4th class rate cellular, since the 4th class cell duration low rate traffic ratio is higher,
It takes and slowly promotes rate, slowly reduce the strategy of rate, it is, meeting rate up-regulation condition, and determine present rate
When less than the second targeted rate, the second targeted rate will be adjusted in rate, and when meeting up-regulation condition next time, continue by
It is adjusted to third targeted rate in rate, alternatively, lowering condition meeting rate, and determines that present rate is greater than the second targeted rate
When, it will be adjusted to the second targeted rate under rate, and when meeting downward condition next time, continues that the first mesh will be adjusted under rate
Mark rate.
For example, some cell belongs to similar set of cells Ф, the reference rate collection in similar set of cells Ф is combined into
{ V1, V2, V3 }, if first object rate is indicated with V1a, the second targeted rate is indicated with V2a, and third targeted rate is V3a table
Show, then:
V1a=min 8*h, (V1-MOD (V1/8) } } [7]
V2a=V2-MOD (V2/8) [8]
V3a=min { VMAXC,max{VEN, (V3-MOD (V3/8)) } } [9]
Wherein, MOD indicates remainder, and 8 be the basic rate of channel in wireless system, and h is positive integer, VENIndicate terminal request
Rate, VMAXCIndicate available maximum rate when cell carries out speed adjust.
For first kind rate cellular, i.e. rate stamps are the cell of A, are adjusted the speed when on some business needs under the cell

For the second class rate cellular, i.e. rate stamps are the cell of B, are adjusted the speed when on some business needs under the cell
When rate, then V3a is directly adjusted to；When some business under the cell needs lower speed change rate, if the business under the cell
Present rate is greater than V2a, then V2a is adjusted to down first, if the business under the cell needs to descend speed change rate again, under continuing
It is adjusted to V1a.
For third class rate cellular, i.e. rate stamps are the cell of C, are adjusted the speed when on some business needs under the cell
When rate, if the present rate of the business under the cell is less than V2a, first on be adjusted to V2a, if the business under the cell needs
Will again upper speed change rate when, then continue on be adjusted to V3a；When some business under the cell needs lower speed change rate, then directly under
It is adjusted to V1a.
For the 4th class rate cellular, i.e. rate stamps are the cell of D, are adjusted the speed when on some business needs under the cell
When rate, if the present rate of the business under the cell is less than V2a, first on be adjusted to V2a, if the business under the cell needs
Will again upper speed change rate when, then continue on be adjusted to V3a；When the cell needs lower speed change rate, if the cell present rate is greater than
V2a is then adjusted to V2a down first, if the business under the cell needs to descend speed change rate again, is adjusted to V1a under continuing.
