For preferably illustrative step S1041 to S1046, now it is explained as follows:
With use of the user to mobile network, the data volume in each block is continuously increased.For single block, when When its data volume reaches predetermined threshold value (100,000), wireless universal propagation model can be based on, intended using big data technology and recurrence Close parameter and regression fit is carried out to each block to obtain multiple block radio transmission models.
It should be noted that for block, due to density of stream of people, the accumulative speed of some block datas is fast, Some block datas add up speed it is slow, generally the block in Chongqing entirely reach 100,000 data take around one about when Between, herein refer to when most slow time, be exactly the minimum block of density of stream of people, to accumulate about one months that 100,000 records need Time., can be by the affiliated administrative region of block by block classification, because administrative region to a certain extent may be used in practical operation To characterize density of stream of people, such as main city zone is just more than the people in outer suburbs, so main city zone data are more, the setting of threshold value can it is big A bit (such as 100,000), outer suburbs data are few, a little bit smaller (such as 50,000) that threshold value is just set.
On the other hand, because administrative region area is excessive, internal environment is unduly complex, and is unfavorable for being fitted, so one Individual administrative region usually contains multiple GIS blocks.
Wherein, wireless universal propagation model is as follows:
Lmodel=K1+K2*log(d)+K3*log(HTexff)+K4*DiffractionLoss+K5*log(d)*
log(HTexff)+K6*HRxeff+Kclutter*f(clutter)
There is involved parameter in the model:K1, constant, unit dB;K2, constant;D, the distance of receiver to emitter (the relative position distance of user and base station), unit is rice;K3, constant;HTexff, transmitting antenna height equivlent (antenna for base station etc. Effect height), unit is rice;K4, constant;Diffraction loss, line penetrate consume, unit dB;K5, constant;K6, constant; HRxeff, reception antenna height equivlent (terminal antenna height equivlent), unit is rice;Kclutter, constant factor;F (clutter), Landform average loss, it is relevant with landforms.Above-mentioned parameter in model can be taking human as manually setting following initial value:K1:160.93; K2:44.90;K3:-13.82;K4:0.20;K5:-6.55;K6:0.00;Kcluter:1.00.
For any one block, there is following anticipation function:
Lmodel=F (d, HTexff, Diffraction Loss, HRxeff, f (clutter))
(1) for any one block, in each calculating cycle T, unequal number amount n (n can be obtained>=105) position The corresponding relation with comment loss is put, relevant parameter is substituted into above-mentioned anticipation function, the initial of each sampled point i can be obtained Predicted value Lpre=F (di, Htxeffi,Diffraction Lossi,HRexffi, f (clutter) i) and actual value Ltrue;Wherein, Relevant parameter refers to d, HTexff、Diffraction loss、HRxeffIt is and resulting in f (clutter) etc., i.e. step S103 Target data.The relevant parameter is resulting after MR data associate with user terminal location.
(2) the deviation d of any sampled point is calculatedL=Ltrue–Lpre+λ;λ is the regular terms for preventing over-fitting.
(3) for sampled point all in each block, total deviation value ∑ d is calculated using step (1) and the method for (2)L =∑ (wt*dL)/∑wt, wherein, according to the time gap current time (model training time) of each sampled point, assign each Sampled point difference weight wi
It should be noted that a period of time T (T typically takes 3 months) is preset, for 0.5 times of T of time between T Sampled point weights are 1,0.5 times of T sampled point are less than for the time, weights reduce and are incremented by with the time, for time T and 2 times of T Between sampled point, weights increase over time and successively decrease, sufficient in available sampling point quantity for 2 times of more than T sampled point In the case of, it is not involved in calculating.
(4) the total deviation value is the function H (K on parameters in wireless universal propagation model1, K2, K3, K4, K5, K6, Kclutter), function H is for each parameter partial derivative.
(5) Ki '=Ki+dH ' ki*dki are modified by local derviation for each parameter.
(6) for the parameters of last time amendment, new predicted value (i.e. target prediction value) can be obtained.
Step (1) to (6) is repeated, optimal parameter K can be obtained1、K2、K3、K4、K5、K6And Kclutter, can be with The radio transmission formula of the block is obtained, i.e., carrying out loop iteration according to target prediction value and actual value calculates to obtain general nothing Target component in line propagation model, target component is substituted into wireless universal propagation model to obtain block radio transmission model.
It should be noted that when repeating step (1) to (6), following two end conditions be present:Cycle-index is more than Preset times N;Average deviation ∑ dL/ n is less than preset value, and n is sampled point number.
It should also be noted that, the process described by step S104, can regard a model training as.First time model During training, the parameter K in wireless universal propagation model1、K2、K3、K4、K5、K6And KcluterInitial value be manually set, and In model training next time, the initial value of above-mentioned parameter is then the result after last model training.
S105, multiple block radio transmission models are carried out to test checking and iteration optimization.
Step S105 includes test checking and two processes of iteration optimization.Wherein, it is as follows to test verification process:
Due to system automation gathered data, using the time sampling point obtained after last time model training, that is, obtain multiple New sampled point.Then, any new sampled point is predicted by block radio transmission model formula, to obtain any new sampling The predicted value and actual value of point, and the predicted value of any new sampled point and the deviation of actual value are calculated, further, calculate The mean error of the deviation of multiple new sampled points.According to the mean error and new sampled point number, it can represent that block is wireless The accuracy of propagation model.
Iterative optimization procedure is as follows:
When the mean error of test checking is more than default error threshold, restarts above-mentioned model training program, model is entered Row re -training.

For any block, according to the initial prediction and reality of any sampled point in the target data calculating cycle T Value;
According to the predicted value and the deviation of any sampled point of calculated with actual values;
The total deviation value of all sampled points in each block is calculated according to the deviation;
Each parameter in wireless universal propagation model is modified to obtain target prediction value according to the total deviation value;
Loop iteration is carried out according to the target prediction value and actual value to calculate to obtain in the wireless universal propagation model Target component;
The target component is substituted into the wireless universal propagation model to obtain block radio transmission model.
10. the optimization device of radio transmission model as claimed in claim 9, it is characterised in that the 3rd processing module tool Body is used for:
Obtain multiple new sampled points;
Any new sampled point is predicted by the block radio transmission model to obtain any new sampled point Predicted value and actual value;
The predicted value of any new sampled point and the deviation of actual value are calculated, and calculates the deviation of multiple new sampled points The mean error of value;
If the mean error is more than default error threshold, optimization is iterated to the block radio transmission model.
