Description
Technical field
The present invention relates to wireless communication technique field, and drive test data track is quickly shown in map more particularly, to a kind of
Method.
Background technology
Drive test (DT) refers to, by the instrument such as instrument or testing mobile phone and test vehicle, nothing be carried out along specific circuit
The measure and collection of line network parameter and speech quality index.Test equipment can record wireless environment parameter and mobile station with
Signaling message between base station, driver test system have the analysis and playback function to test record data.The purpose of drive test is simulation
The call state of mobile subscriber, record data simultaneously analyzes these data, these data compared with original network design data
Compared with, if variant and abnormal call information, try change various parameters, to optimize network.Drive test is the network optimization
Important means, assessment of the parameter, calling connection situation and tester that drive test is gathered to speech quality, is provided for operator
More complete network coverage situation, the also analysis for network operation situation provide more sufficient data basis.Due to
Drive test can record and play back all information in test process, very big for fault location and recruitment evaluation effect, especially
It is for the effect in terms of call drop point location.
Existing drive test software is shown that the data message amount of drive test data is big according to each test sample data, is shown
Show less efficient.There is presently no effective solution.
Mobile communication drive test and the data and geography information of analysis system are closely related, need to be by the figure of GIS-Geographic Information System
Shape display capabilities, the convenient data that test is intuitively presented, check and analyze network condition, help orientation problem.Ground figure
Formula, which is presented, to provide more information than simple chart, figure, and it is simpler more fast than description tables of data to describe map.Such as
Map and drive test can be effectively combined by what, the problem of turning into mobile communication drive test and analysis system urgent need to resolve.
The content of the invention
Method problem solved by the invention is to provide a kind of method for quickly showing drive test data track in map, this hair
The coordinate value of bright drive test data test sample point is that the coordinate value gathered according to GPS device is obtained by projection coordinate's interpolation calculation
Arrive, GPS device has the characteristics of sampling time is relatively more fixed, data volume is small, quick to calculate by first traveling through raw GPS data
Go out to need the point drawn, so as to reduce the drafting number of sampled point, improve drawing efficiency.The present invention can quickly judge,
Invisible or most of overlapping point is skipped, greatly accelerates display speed.User can obtain when map window browses data
To quick response.
