Step 202: utilize the signal level in the propagation model compute location zone after correcting to distribute;
Step 203: set up based on the incoming level database of predicting according to result of calculation;
According to actual needs locating area is divided into each grid, the length of side of each grid is represented actual range, above-mentioned incoming level database based on prediction is a unit with each grid, write down the positional information of each grid representative, the sub-district under the level intensity of the signal that terminal can receive in this position and the signal that terminal can receive.For example: the actual range that the length of side of each grid is represented is 100m, and then a grid represents that actual area is the square of 100m*100m.
Every record of incoming level database comprises the cell ID of positional information and this position and the corresponding relation of the signal level intensity that terminal can receive in this position.
Step 204: the MR that the base station controller receiving terminal reports;
Step 205: base station controller carries out absolute value coupling and relative value coupling according to MR to each grid of locating area;
Respectively absolute value configuration and relative value coupling are elaborated below.
(1) absolute value coupling
Each geographical position in the wireless network all has unique characteristic information, these characteristic informations comprise: geography information, cell information and level information, particularly, characteristic information comprises: the level intensity of the signal that sub-district under the signal that the longitude and latitude in this geographical position, terminal can receive in this geographical position and terminal receive in this geographical position.Owing to comprise the sub-district under the signal that terminal receives in a geographical position among the MR that receives of base station controller, so the embodiment of the invention is a benchmark with the level intensity of each sub-district among the MR, the prediction received signal level of each grid in the level intensity of each sub-district and the locating area is carried out the absolute value coupling.
The absolute value coupling is a benchmark with MR, at each grid, can comprise following step:
1, from the pairing information of grid, search the information that whether comprises the Serving cell among the MR,, enter next step 2, otherwise flow process finishes, and perhaps, directly enters step 3, relatively the next information of MR if comprise;
2, adjudicate the degree of approximation of the level intensity of the pairing Serving cell signal of this grid with the level intensity of Serving cell signal among the MR;
Judging process can be according to following principle:
(a) the prediction received signal level of grid and the received signal level among the MR are approaching more, and then the feature of this grid and measurement report information are approaching more.
Or (b) the weight maximum of the received signal level of Serving cell correspondence in the absolute value coupling among the MR, secondly be the last the first adjacent area of Serving cell among the MR, the weight of other adjacent area is successively decreased successively.
Or (c) according to the arrangement of sub-district in the measurement report, if the plot continuity of the corresponding coupling that finds is good more in the grid information, then the matching with measurement report is good more.
Realize the coupling of absolute value according to above principle.Wherein principle c compares with principle a, to matching result to influence role more obvious, so also solved the problem that becomes when the actual wireless network environment is preferably.
3, from the pairing information of this grid, search the information of the last the first adjacent area that whether comprises Serving cell among the MR,, enter next step, otherwise flow process finishes, perhaps, compare the next information among the MR if comprise;
4, utilize mentioned above principle to adjudicate the degree of approximation of the level intensity of pairing the last the first neighboring area signal of this grid with the level intensity of the last the first neighboring area signal among the MR, the judgement principle of degree of approximation is identical with step 2;
The information of all sub-districts all compares with the pairing information of this grid in MR, assess according to all sub-districts approximate situation relatively among the MR again, when all sub-districts among the MR and the pairing information of this grid are all consistent, the result that can represent the absolute value coupling with numerical value 0, when not having consistent information, can represent with numerical value 1, when the information of part sub-district in the information of all sub-districts is consistent, can be with the numeric representation between 0 to 1.
(2) relative value coupling
Because factors such as engineering parameter, propagation model are inaccurate make the absolute value coupling may have deviation.The relative value coupling can be offset the deviation that the absolute value coupling produces.This be because: because the time-varying characteristics of wireless environment, sometimes the MR that reports can not reflect truly that terminal can receive the situation of signal in the network site, such as: terminal fails to receive a signal instantaneous, but terminal constantly just might receive this signal at other.Absolute value coupling can't identify this situation, and the relative value coupling will be used simultaneously from the signal of two sub-districts and weighs, so just the inaccuracy that can avoid the wireless environment transient change to bring to a certain extent.
The embodiment of the invention is carried out relative value coupling and is comprised: at each grid, according to the received signal level of each sub-district among the MR that receives, each adjacent area received signal level of Terminal Service sub-district is obtained first group of numerical value divided by the Serving cell received signal level.Each adjacent area received signal level of prediction Serving cell is obtained second group of numerical value divided by prediction Serving cell received signal level.According to following relative value matching principle first group of numerical value and second group of numerical value are mated.
The principle of relative value coupling is:
The relative reception level ratio of grid prediction and the relative reception level ratio that measures are more near (promptly first group of numerical value and second group of numerical value are approaching more), and this grid is reasonable more as anchor point.
After first group of data and second group of Data Matching are intact, a numerical value is set at the comprehensive all matching results of each grid.
Step 206: the comprehensive absolute value coupling of base station controller is mated the grid of determining the terminal location place with relative value.
Carried out after absolute value coupling and the relative value coupling, each grid in the locating area is calculated a numerical value, the geographical position of each grid representative of this numeric representation and the degree of approximation of terminal location are represented this numerical value with cost, and the cost value of each grid is:
cost
i＝α·L
i1+β·L
i2
Wherein, cost
iBe the cost value of i grid, L
I1Be that i grid is the value that the absolute value coupling is provided with, L
I2Be that i grid is the value that the relative value coupling is provided with, α is the weight of absolute value coupling, and β is the weight of relative value coupling.If the accuracy of prediction incoming level database is very high, promptly the degree of approximation of data predicted and drive test numerical value is greater than presetting thresholding, and then the value of α is bigger with respect to β.If the precision of prediction incoming level database is not high, then the value of β is bigger with respect to α.
At last, in the cost of all grids value, the pairing geographical position of grid that the cost value is minimum is defined as the position of terminal.
In the embodiment of the invention two, the absolute value coupling has higher precision when wireless network environment is comparatively stablized, therefore, when wireless network environment is comparatively stablized, the weight of relative value coupling can be provided with less numerical value, the absolute value coupling can be provided with bigger numerical value, when wireless network environment is unstable, the weight of relative value coupling can be provided with bigger numerical value, the absolute value coupling can be provided with less numerical value, and the result of mating by relative value compensates the result that absolute value mates, thereby, when wireless network environment is unstable, still can obtain the positioning accuracy of higher definite terminal location by the embodiment of the invention.
Alternatively, can also be by setting up the higher incoming level database of precision, or utilize revised unit interval lead (TA, Time Advance) propagation distance determines that the higher locating area of precision improves positioning accuracy, utilizes TA to determine that the higher locating area of precision improves positioning accuracy when perhaps setting up the higher incoming level database of precision.
Please refer to Fig. 3, the method schematic diagram for the embodiment of the invention three definite terminal locations can may further comprise the steps:
Step 301: the engineer carries out drive test to locating area;
Step 302: the computer that specific software has been installed utilizes drive test data that propagation model is corrected, and the propagation distance of the TA of unit is revised;
Propagation model corrected comprise: drive test data is converted to continuous wave, and (CW, ContinuousWave) test data utilize the CW test data that propagation model is corrected.After the rectification, drive test data is used in the zone that drive test data is arranged, do not have the zone of drive test data to use prediction data.
TA among the MR can assist and position, and promptly comes assist location by the distance of the radio propagation in the TA duration.According to the radio transmission principle, the radio transmission of the TA of unit correspondence distance is:
The every bit duration of 1/2* * velocity of radio wave ≈ 550m
In the communication environments of reality, multipath fading makes the wireless signal of a TA time might not propagate 550m.If all to TA value 550m, certainly will influence locating accuracy in any scene.Therefore, the embodiment of the invention is revised the propagation distance of the TA of unit according to drive test data at different scenes, different locating areas.
Propagation distance correction to the TA of unit comprises: a MR comprises a TA, at each MR among a large amount of MR, utilizes the TA among the MR to calculate the time of the base station of Serving cell to drive test point; The time that calculates multiply by 550m and obtains the distance of the base station of Serving cell to drive test point; Match is carried out to the distance of drive test point in base station to a large amount of TA and the Serving cell that obtains respectively, thereby realizes the propagation distance of the TA of unit is revised.
Step 303: this computer utilizes drive test data and prediction data to set up the incoming level database according to the propagation model after correcting;
The incoming level database of setting up is at each grid, the road test data smoothing processing that disperses; Predict based on following principle then: have the grid of drive test data to use drive test data as characteristic information, the grid that does not have drive test data is by predicting that the information of coming out is as characteristic information.
Step 304: the MR that the base station controller receiving terminal reports;
Step 305: base station controller dwindles locating area according to the TA among the MR of terminal to report, and obtains the incoming level database from this computer;

For example: suppose that the TA among the MR is 2, the propagation distance of the revised TA of unit is 500m, with 401 is initial point, with 1000m (2*500m=1000m) is radius, can obtain a camber line, deduct 0.5 with 2 and obtain 1.5, with 401 is initial point, with 750m (1.5*500m=750m) is that radius can obtain a camber line, add that with 2 0.5 obtains 2.5,401 to be initial point, be that radius can obtain a camber line with 1250m (2.5*500m=1250m), after zone between two camber lines obtaining be locating area.
