In said method, optionally, determine each user quality of service method can by following steps come
Realize：
Step 1, the MRO (MR Original, the measurement that obtain each base station from measurement report server
Report sample data) file, reads the time T, user temporary mark MMEAPID of every surveying record
(Mobility Management Entity Application Identification, mobile management nodes application of function
Program identification), Serving cell level SRSRP, adjacent cell level NRSRP；
Step 2, from S1-MME (S1-Mobility Management Entity, S1- mobile management nodes work(
Can) interface signaling obtains the time T of each user, user's temporary mark MMEAPID and user are unique
Mark IMSI (International Mobile Subscriber Identification Number, international mobile subscriber
Identification code)；And from S1-MME interface signaling obtain each user Attach (attachment) success rate,
InitContextSetup (default bearing foundation) success rate, PDN (Public Data Network, public number
According to net) success rate, TCP (Transmission Control Protocol, transmission control protocol) success rate,
HTTP (HyperText Transfer Protocol, HTML (Hypertext Markup Language)) success rate, UE (User
Equipment, user equipment) drop rate, flow and TAU (Tracking Area Update, tracking area
Update) success rate；
Step 3, by time T and ID MMEAPID, by every surveying record of MRO and
User's matching association of S1-MME interface signaling data, obtains MR and reports the user of every surveying record only
One mark IMSI；
Step 4, by user's unique mark IMSI, the unique mark in measurement report MR can be retrieved
All surveying records of the user corresponding to IMSI, and calculate the average covering level RSRP of the useruser；
Step 5, based on the Attach success rates of the acquisition in step 2, InitContextSetup success rates,
PDN success rates, TCP success rates, HTTP success rates, UE drop rates, flow and TAU success rates
Deng, and the average covering level RSRP obtained in step 4user, it is complete by evaluation the quality system computing
Net the quality of service Q of each useruserIf, QuserLess than the 3rd threshold value, the user is exactly a business matter
The user of amount difference, wherein the value of the 3rd threshold value is depending on being actually needed.
By above step 1～5, it may be determined that the user for going out quality of service difference.
After determining the surveying record of each user in above-mentioned steps 4, it may also be determined that going out what each user was located
Grid, the method that the surveying record of each user is navigated to some grid specifically can for example be traditional
Triangulation location, or fingerprint location method etc., are not specifically limited to this application.
In above-mentioned steps 5, can be by the quality of service of each user of evaluation the quality system computing the whole network
Quser, can refer to the quality of service Q that table 1 and meter calculate useruser, wherein table 1 is evaluation the quality body
Mark segmentation normalization marking rule is meant, 2 evaluation the quality system index weights of table are arranged, according to user
Each index score and weight, calculate the final quality of service Q of useruser。
1 evaluation the quality system index of table segmentation normalization marking rule
2 evaluation the quality system index weights of table are arranged
Covering for such as user A must be divided into 4 points, and TAU must be divided into 5 points, and Attach must be divided into 5 points,
InitContextSetup must be divided into 3 points, and TCP must be divided into 1 point, and HTTP must be divided into 2 points, PDN scores
For 4 points, UE goes offline and must be divided into 3 points, and TRAF must be divided into 2 points, then can determine that the final of user A is obtained
It is divided into 4*0.065+5*0.153+5*0.013+3*0.142+1*0.166+2*0.156+4*0.123+ 3*0.026
+ 2*0.156=2.876.Furthermore it is also possible to the final score of each user is normalized to into 5 points, and 4 points, 3
Point, 2 points, in 1 point, therefore the final score of user A can be normalized to 3 points, if now
3rd threshold value value is 4 points, then user A is user of poor quality.
After the surveying record of each user is navigated to certain grid, can be according to the business of the user in grid
Quality, determines the service coverage quality of grid.Specifically, can calculate in the following manner：
With grid as dimension, the total sampling number S of user of each grid is countedtotal-userIt is poor with quality of service
User's is total using points Sbad-userIf the business matter difference of a grid is using point ratio
Vgrid=Sbad-user/Stotal-user>T1 (such as T1 can value be 50%), then the grid is exactly one
The excessively poor grid of individual service coverage quality；If T1>Vgrid>T2 (such as T2 can value be 30%),
Then the grid is exactly a second-rate grid of service coverage；If Vgrid<T2, then the grid is exactly one
The grid of individual service coverage requisite quality.
The industry of a grid is determined above by the ratio shared by the user of quality of service difference in a grid
The method of business covering quality, is associated with the quality of service of each user, can calculate the business matter of user class
Amount, is effectively found individual user's quality of service problem, thus can solve traditional industry calculated based on cell
Business covering quality cannot reflect the problem of individual user's quality of service situation.
After said method determines, each grid has a service coverage qualitative attribute, is to cover very
Difference, the one kind covered during poor and covering is up to standard.
Wherein, grid that can be by service coverage quality higher than the 4th threshold value is defined as the ropy grid of service coverage
T2 values in above-mentioned example such as can be defined as the 4th threshold value by lattice, thus service coverage quality is higher than the
The grid of four threshold values is then the ropy grid of service coverage, will go up service coverage quality in example it is excessively poor and
The second-rate grid of service coverage is defined as the ropy grid of service coverage.
In addition, a user can correspond to a plurality of surveying record, due to the mobility of user, user's correspondence
A plurality of surveying record may correspond to multiple grids, such as user 123 has 5 surveying records A, B, C,
D, E, wherein surveying record A, B correspondence grid Gs rid1, surveying record C, D correspondence grid G rid2,
Surveying record C correspondence grid Gs rid3, then for corresponding which grid of a user how determined, will have
A variety of modes, for example, can be using the grid corresponding to the surveying record of user 123 as user 123
Corresponding grid, then user 123 respectively correspond to grid G rid1, Grid2, Grid3, thus calculate grid
During the service coverage quality of the grid of lattice Grid1, Grid2, Grid3, three grids can be by user 123
Count.For the grid for how determining that each user is located, the embodiment of the present application gives a kind of mode.
Optionally, the grid for determining that each user is located, including：
Determine in the surveying record of user that grid that first surveying record is located is the grid that the user is located.
The grid at first surveying record place in the surveying record of user is defined as the user by said method
The grid at place, can quickly position the grid at user place, and as a user only corresponds to grid
Lattice, thus system effectiveness can be improved, save system resource.
In a step 102, using service coverage ropy grid as grid to be assessed, wherein service coverage
Quality can be assessed with the 4th threshold value, and for example, the embodiment of the present application will determine grid business in step 101
The T2 values of the threshold value of covering quality are defined as the 4th threshold value, will service coverage quality higher than T2 grid make
For grid to be assessed, show using service coverage qualitative attribute be cover it is excessively poor and cover poor grid as
Grid to be assessed.
After determining grid to be assessed, and then determine the adjacent cells set of each grid to be assessed, wherein,
The adjacent cells set of n-th grid to be assessed is by apart from the nearest K of n-th grid to be assessed
Grid composition to be assessed, K is positive integer set in advance.For example grid m-th to be assessed is represented not
XM, it is determined that the grid to be assessed for going out is XMAdjacent cells collection be combined into XM{n1,n2,…,nK, above-mentioned K
It is worth for being previously set, depending on concrete value can depend on actual need, the embodiment of the present application provides a kind of preferred K
Value, i.e. K values are the adjacent cells set of the grid to be assessed of 20, i.e., by apart from the grid to be assessed
20 nearest grid compositions to be assessed of lattice.
In step 103, according to the adjacent cells set of m-th grid to be assessed with except m-th it is to be evaluated
Estimate the similarity of the adjacent cells set of grid to be assessed outside grid, it is then, to be evaluated according to m-th
The adjacent cells set for estimating grid is adjacent with the grid to be assessed in addition to m-th grid to be assessed
The similarity of grid set, determines whether m-th grid to be assessed is core grid, in actual applications,
To then need according to the adjacent cells set of m-th grid to be assessed with except m-th grid to be assessed it
The similarity of the adjacent cells set of outer grid all of to be assessed determining m-th grid to be assessed is
It is no for core grid, it is desired nonetheless to according to the adjacent cells set of m-th grid to be assessed with remove m-th
