State equation of uniting it is derivative come, therefore, first to establish business datum that business data model is k period and K-1 period it
Between the background of corresponding relationship be illustrated.
Firstly, introducing system state equation, specific formula are as follows:
X(k)=AX(k-1)+BU(k)+W(k)... formula (1)；
If the measured value for the system of adding:
Z(k)=HX(k)+V(k)... formula (2)；
It states in two formula, X(k)Indicate the system mode at k moment, Z(k)Indicate the measured value at k moment, U(k)It is the k moment to being
The control amount of system.A and B is system parameter, and H is the parameter of measuring system, W(k)And V(k)The noise of process and measurement is respectively indicated,
Carry out the optimization output of estimating system below with reference to variance.
Later, the process model that can use system, the system for predicting NextState.If present system mode is k
If, present status is predicted according to formula (1):
X(k|k-1)=AX(k-1|k-1)+BU(k)... formula (3)；
X(k|k-1)Being is exactly to be predicted using laststate as a result, and X(k-1|k-1)It is that laststate is optimal as a result, U(k)
It is then the control amount of present status, if forecasting system does not have control amount, it can be arranged 0 by we.
This is arrived, system results have just had updated, but correspond to X(k|k-1)Covariance also do not update.It indicates to assist with P
Variance introduces formula:
P(k|k-1)=AP(k-1|k-1)A '+Q ... formula (4)；
In formula (4), P(k|k-1)It is exactly X(k|k-1)Corresponding covariance, P(k-1|k-1)It is X(k-1|k-1)Corresponding covariance, A` are
The transposed matrix of A, Q are the covariances of systematic procedure.
In conjunction with predicted value and measured value, so that it may obtain the maximum likelihood estimate X of present status (k)(k|k):
X(k|k)=X(k|k-1)+Kg(k)(Z(k)-HX(k|k-1)) ... formula (5)；

Kg(k)=P(k|k-1)H′/(HP(k|k-1)H '+Q) ... formula (6)；
According to (6) two formula of above-mentioned formula (5) and formula, we have obtained optimal estimated value X at this time(k|k).But it is intended to
It allows algorithm constantly to run, also to update X under k-state(k|k)Variance:
P(k|k)=(I-Kg(k)H)P(k|k-1)... formula (7)；
Wherein I is matrix, and I is equal to l in single measurement model.When system enters k+l state, P(k|k)Formula (4) are become
P (k-1 | k-1).In this way, algorithm can go down in recursive operation automatically.Business data model in the present embodiment be then with

Battle array；
S3, according to the business datum at business datum system k-1 moment, according to formula X(k|k-1)=AX(k-1|k-1)+BU(k), meter
It calculates and obtains the predicted state A of the business datum system at k moment(x(k))；
S4, according to formula P(k|k-1)=AP(k-1|k-1)A′+Q、A(x(k))And P(k-1|k-2)Calculate covariance matrix P(k|k-1),
In, P(k-1|k-2)According to formula P(k|k)=(I-Kg(k)H)P(k|k-1)It obtains；A ' is the transposed matrix of A；P(k|k-1)For X(k|k-1)It is corresponding
Covariance；P(k-1|k-1)For X(k-1|k-1)Corresponding covariance；Kg(k)For the gain matrix of the business datum system at k moment
Kg(k)；
S5, according to formula Kg(k)=P(k|k-1)H′/(HP(k|k-1)H '+R), calculate the gain of the business datum system at k moment
Matrix K g(k)；
S6, according to gain matrix Kg(k)With formula X(k|k)=X(k|k-1)+Kg(k)(Z(k)-HX(k|k-1)), obtain optimum prediction
Estimate value matrix
S7, judge whether the business datum at all moment has estimated completion, if so, terminating；If it is not, then repeating S3-S6.
By above-mentioned steps it is found that A in business data model(x(k))Be according to k+1 moment pervious history service data come
It determines, therefore business data model itself is time-varying system, and the variance of system noise and observation noise also real-time update, institute
It is capable of the variation of adaptive top n period business datum with this model.In addition, the H in observational equation(k)It is also according to history
Data are established using statistical method.
Wherein, value matrix is estimated in the optimum prediction of the business of calculatingWhen, mainly by gain K(k)And association
Variance P(k+1/k)Influence, in order to make optimum prediction estimation traffic value more tap into true portfolio, can be in terms of two
Start with, first is exactly that gain is maximumlly corrected to estimation predicted value, second is that being directly modified to predicted value.Traffic forecast tool
There is certain hysteresis quality, it is lower especially for the accuracy of the period that portfolio changes greatly, prediction.In response to this,
We can directly to business optimum prediction estimated valueIt is modified.A business correction factor is added in we at this time
TRA_Rate, available formula:
TRA in above formula(k+1/k)It is exactly the forecast value revision value of business datum, the main key point of the improvement of algorithm is
TRA_Rate(k+1/k)In acquisition, it will be assumed now that we have enough business datums, and know again portfolio have must week
The feature of phase property, the business datum that historical period can be used obtain to business correction factor.
S13, according to the business datum for the subsequent time of the cell being calculated, according to preset algorithm to cell classification,
Determine the power saving class of the subsequent time of the cell.
