Perhaps.
Step S103 obtains mobile terminal and becomes at any time according to the longitude and latitude and corresponding time of origin of adjacent position point
The longitude and latitude of change.
Wherein, the mobile terminal that obtained mobile terminal switches or the location point of gravity treatment records in test file
It switches or the time of origin of gravity treatment is corresponding.This can obtain the longitude and latitude that mobile terminal changes over time to a certain extent
Degree, obtains the corresponding relationship of mobile terminal longitude and latitude and time, but the density of location point is small, can only obtain mobile terminal minority
Longitude and latitude.In a kind of possible embodiment, according to the longitude and latitude and corresponding time of origin of adjacent position point, moved
The longitude and latitude that terminal changes over time may include:
(b1) difference of the longitude and latitude of adjacent position point and the difference of corresponding time of origin are pressed into identical numerical value equal part,

It is bright.If the longitude and latitude of two adjacent position points is respectively (100.0 °, 80.0 °) and (101.0 °, 81.0 °), when corresponding generation
Between be respectively 2014/1/113:30:00 and 2014/1/113:31:00, then the difference of longitude be 1 (by degree as unit of), latitude
Difference be also 1 (as unit of degree), the difference of corresponding time of origin is 60s.Usual mobile network's testing time unit can
To reach Millisecond, the present embodiment is to make to illustrate briefly conveniently, using the second as the minimum unit of time.It then can be by time of origin
Difference carries out equal part as unit of 1s, i.e., is 60 parts, time step 1s by 60s point, correspondingly, the difference of latitude and longitude
Difference is also all divided into 60 parts, then longitude step-length and the step-length of latitude are all 1/60 °, and taking approximation is 0.017 °.
After obtaining longitude and latitude step-length and time step, just can obtain range (100.0 °, 80.0 °) to (101.0 °,
81.0 °) longitude and latitude degree series, i.e., started with (100.0 °, 80.0 °), longitude and latitude is gradually incremented by by longitude and latitude step-length, obtains longitude and latitude
Degree series be [(100.0 °, 80.0 °), (100.017 °, 80.017 °), (100.034 °, 80.034 °), (100.051 °,
80.051°)……].Time of origin sequence is then [13:30:00,13:30:01,13:30:02 ...].
It is after obtaining longitude and latitude degree series and time of origin sequence, longitude and latitude degree series and time of origin sequence are corresponding, i.e.,
(100.017 °, 80.017 °) corresponding time 13:30:01, (100.034 °, 80.034 °) corresponding time 13:30:02, with such
It pushes away, to obtain the longitude and latitude that more detailed mobile terminal changes over time, obtains the latitude and longitude information of more mobile terminals.
In railway mobile network test, according to the longitude and latitude and corresponding time of origin of adjacent position point, moved
The longitude and latitude that terminal changes over time, can also be corresponding by length of the railroad track between the point of adjacent position and adjacent position point

In the mapping point of railroad track.Wherein, if mobile terminal is to be moved to Z from X, mobile terminal can occurs between X and Y-1 and cut
It changes or gravity treatment, after mobile terminal switching or gravity treatment occurs, it is that mobile terminal switching occurs that mobile terminal is corresponding in Y-1 ' point
Or after gravity treatment level waveforms first wave crest, the peak time of first wave crest can be from waveform or the record of test file
It obtains, the longitude and latitude of the peak time of first wave crest and Y-1 ' is corresponding to get to the one of mobile terminal longitude and latitude and time
A corresponding relationship, and so on available mobile terminal at Y-2 ', Y-3 ' respectively at second peak time and third
