Step 7) empties tranining database.
The detailed step that communication data is put into sample database in the step 2), step 6) is as follows:
Step A), communication data is stored in sample database；
Step B), all data in sample database are ranked up from big to small according to its posterior probability；
Step C), if the quantity of the data in sample database is less than or equal to preset max-thresholds, retain sample
All data in database；
Step D), if the quantity of the data in sample database is greater than preset max-thresholds, n item number before retaining
According to, delete remaining data, n is equal to preset max-thresholds.
