If quality of service is lower than the user of third threshold value, it is determined that the user is the user of quality of service difference；
If ratio shared by the user of quality of service difference is greater than the 4th threshold value in the corresponding all users of grid, it is determined that should
Grid is the ropy grid of service coverage.
The above method is corresponding with multiple users in one grid, by user's accounting ropy in corresponding all users
Grid greater than the 4th threshold value is determined as the ropy grid of service coverage, thus this method can be by the service coverage matter of grid
The quality of service of user corresponding with grid is measured to association, the service condition based on user can reflect whole network well
Service coverage quality.
In the above method, optionally, the method for determining the quality of service of each user can be realized by following steps:
Step 1, MRO (MR Original, the measurement report sample number that each base station is obtained from measurement report server
According to) file, read the time T, user's temporary identifier MMEAPID (Mobility Management of every measurement record
Entity Application Identification, mobile management nodes functional application mark), serving cell level
SRSRP, adjacent cell level NRSRP；
Step 2, from S1-MME (S1-Mobility Management Entity, S1- mobile management nodes function) interface
Signaling obtains the time T of each user, user's temporary identifier MMEAPID and user unique identification IMSI (International
Mobile Subscriber Identification Number, international mobile subscriber identity)；And from S1-MME interface
Signaling obtains Attach (attachment) success rate of each user, InitContextSetup (default bearing foundation) success rate, PDN
(Public Data Network, public data network) success rate, TCP (Transmission Control Protocol, transmission
Control protocol) success rate, HTTP (HyperText Transfer Protocol, hypertext transfer protocol) success rate, UE
(User Equipment, user equipment) drop rate, flow and TAU (Tracking Area Update, tracing section updating) at
Power；
Step 3 passes through time T and user identifier MMEAPID, by the every measurement record and S1-MME interface signaling of MRO
The user of data matches association, obtains user's unique identification IMSI that MR reports every measurement record；
Step 4 passes through user's unique identification IMSI, can retrieve in measurement report MR corresponding to unique identification IMSI
User all measurements record, and calculate the average covering level RSRP of the useruser；
Step 5, the Attach success rate based on the acquisition in step 2, InitContextSetup success rate, PDN success
The average covering electricity obtained in rate, TCP success rate, HTTP success rate, UE drop rate, flow and TAU success rate etc. and step 4
Flat RSRPuser, pass through the quality of service Q of each user of evaluation the quality system computing the whole networkuserIf QuserLess than third
Threshold value, the user are exactly the user of a quality of service difference, and wherein the value of third threshold value is depending on actual needs.
Pass through above step 1~5, it may be determined that go out the user of quality of service difference.
After the measurement record for determining each user in above-mentioned steps 4, it can also determine the grid where each user, have
The measurement record location of each user to the method for some grid, such as can be traditional triangulation by body, can also be with
It is fingerprint positioning mode etc., this application is not specifically limited.
In above-mentioned steps 5, the quality of service Q of each user of evaluation the quality system computing the whole network can be passed throughuser, can join
The quality of service Q of user is calculated according to table 1 and meteruser, wherein table 1 is evaluation the quality system index segmentation normalization marking rule
Then, 2 evaluation the quality system index weights of table are arranged, and according to the score and weight of each index of user, calculate user
Final quality of service Quser。
1 evaluation the quality system index of table segmentation normalization marking rule
The setting of 2 evaluation the quality system index weights of table
For example the covering of user A is scored at 4 points, TAU is scored at 5 points, and Attach is scored at 5 points,
InitContextSetup is scored at 3 points, and TCP is scored at 1 point, and HTTP is scored at 2 points, and PDN is scored at 4 points, and UE goes offline score
It is 3 points, TRAF is scored at 2 points, then can determine that the final score of user A is 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 which the final of each user is obtained
Divide one be normalized in 5 points, 4 points, 3 points, 2 points, 1 point, therefore the final score of user A can be normalized to 3 points, at this time
If third threshold value value is 4 points, user A is user of poor quality.
After the measurement record location to some grid by each user, can according to the quality of service of the user in grid,
Determine the service coverage quality of grid.Specifically, it can calculate in the following manner:
Using grid as dimension, the total sampling number S of user of each grid is countedtotal-userWith the user's of quality of service difference
Total sampling number Sbad-userIf the business matter difference sampled point ratio V of a gridgrid=Sbad-user/Stotal-user> T1 (example
As T1 can value be 50%), then the grid is exactly the excessively poor grid of service coverage quality；If T1 > Vgrid> T2 (example
As T2 can value be 30%), then the grid is exactly the second-rate grid of service coverage；If Vgrid< T2, the then grid
It is exactly the grid of a service coverage requisite quality.
Ratio shared by user above by quality of service difference in a grid determines the service coverage of a grid
The method of quality, it is associated with the quality of service of each user, the quality of service of user class can be calculated, effectively discovery is individual uses
Family quality of service problem, thus can solve it is traditional based on cell calculate service coverage quality can not reflect individual user's industry
The problem of business quality condition.
After being determined by the above method, each grid has a service coverage qualitative attribute, to cover excessively poor, covering
It is poor and cover one of up to standard.
Wherein, the grid that service coverage quality is higher than the 4th threshold value can be determined as the ropy grid of service coverage, than
T2 value in above-mentioned example can be such as determined as to the 4th threshold value, thus it is then industry that service coverage quality, which is higher than the grid of the 4th threshold value,
The grid for covering quality difference of being engaged in is determined as service coverage quality in upper example is excessively poor with the second-rate grid of service coverage
The ropy grid of service coverage.
In addition, a user can correspond to a plurality of measurement record, due to the mobility of user, the corresponding a plurality of survey of a user
Amount record may correspond to multiple grids, such as user 123 has 5 measurements record A, B, C, D, E, wherein measurement record A, B is corresponding
Grid G rid1, measurement record C, D correspond to grid G rid2, and measurement record C corresponds to grid G rid3, then for how to determine one
Which grid user corresponds to, will be there are many kinds of mode, for example, can be equal by the corresponding grid of the measurement record of user 123
As grid corresponding to user 123, then user 123 respectively corresponds grid G rid1, Grid2, Grid3, thus in computation grid
When the service coverage quality of the grid of Grid1, Grid2, Grid3, which can be counted user 123.For
How grid each user where is determined, the embodiment of the present application gives a kind of mode.
Optionally, the grid where each user of the determination, comprising:
Determine that the grid in the measurement record of user where first measurement record is the grid where the user.
Grid where first measurement record in the measurement record of user is determined as where the user by the above method
Grid can quickly position the grid where user, and since a user only corresponds to a grid, thus can be improved and be
System efficiency, has saved system resource.
In a step 102, using the ropy grid of service coverage as grid to be assessed, wherein service coverage quality can be with
It is assessed with the 4th threshold value, for example, the embodiment of the present application will determine the T2 value of the threshold value of grid service coverage quality in step 101
It is determined as the 4th threshold value, i.e. the grid using service coverage quality higher than T2 shows as grid to be assessed by service coverage quality
Attribute is the excessively poor grid poor with covering of covering 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 n-th
The adjacent cells set of grid to be assessed is made of the K nearest apart from n-th grid to be assessed grids to be assessed, and K is
Preset positive integer.Such as m-th grid to be assessed is indicated into non-XM, it is determined that the grid to be assessed gone out is XMIt is adjacent
Grid set is XM{n1,n2,…,nK, above-mentioned K value is to be previously set, and depending on specific value can depend on actual need, the application is real
It applies example and provides a kind of preferred K value, i.e., K value is 20, i.e., the adjacent cells set of one grid to be assessed should be to by distance
Assess 20 nearest grid compositions to be assessed of grid.
In step 103, according to the adjacent cells set of m-th grid to be assessed and in addition to m-th grid to be assessed

The similarity of the adjacent cells set of grid to be assessed except the m-th grid to be assessed, determines m-th grid to be assessed
Whether be core grid, in practical applications, until then need according to the adjacent cells set of m-th grid to be assessed with except the
The similarity of the adjacent cells set of all grids to be assessed except M grids to be assessed determines m-th grid to be assessed
Whether lattice are core grid, it is desired nonetheless to according to the adjacent cells set of m-th grid to be assessed and remove m-th grid to be assessed
Except the similarity of adjacent cells set of grid to be assessed of part determine whether m-th grid to be assessed is core grid
Lattice, then can be by by m-th therein grid to be assessed for example, one shares 100 grids to be assessed depending on actual conditions
Adjacent cells set compared with the adjacent cells set of 99 other grids, determine the adjacent of m-th grid to be assessed
The similarity of the adjacent cells set of grid set and 99 other grids, so determine m-th grid to be assessed whether be
Core grid；Or be also possible to m-th grid to be assessed adjacent cells set and other 99 grids in part grid
The adjacent cells set of (such as 10) compares, determine m-th grid to be assessed adjacent cells set and other 99 grid
