Wherein, one Serving cell of each sampled point correspondence and multiple adjacent areas.Each sampled point is being moved The signal intensity of the Serving cell of its service and adjacent with its Serving cell can be sampled as in the dynamic time Cell signal intensity.

For the concrete mode of the effective sampling number of covering of target area in statistics S1042, this hair Bright embodiment is not defined to this, exemplary, can be in the following manner：

Due to, the identification information of each cell in drive test region can be obtained from drive test data, lead to The identification information for crossing the cell may determine that whether the cell is cell in target area, and be The cell of structuring base station covering, structuring is filtered out from the drive test data according to identification information The cell of base station covering, for example, as shown in table 2, any one sampled point is obtained from table 2 The PCI of Serving cell, in judging the PCI with the presence or absence of the station list described in table 1, if in the presence of Then illustrate the Serving cell sampled as sampled point with the cell under the covering of structuring base station Cell, signal intensity is more than or equal to default letter in counting the sampling number with the cell as Serving cell The sampling number S of number intensity_erv, and it is cell and signal under structuring base station to be unsatisfactory for Serving cell Intensity more than or equal to preset signal strength but exist at least one adjacent area be structuring base station under cell and Sampling number S of the signal intensity more than or equal to preset signal strength_nbr, all listed by table 2 are belonged to The effective sampling number of covering of the cell of structuring base station is added S_{effectivecoverage}=S_serv+S_nbr, as Cover effective sampling number.

Wherein, the preset signal strength of the embodiment of the present invention is -105dBm.

It is exemplary, longitude of the drive test data resolution table also including each Serving cell and The sampling time of latitude and each sampled point, as shown in Fig. 2 the drive test data after the parsing Also include sampling time, the sampling geographical location information, the geographical location information of each sampled point Including longitude and latitude, the effective sampling number of covering of the acquisition target area can pass through Following steps realize S10421A-S10421D：
