Abstract: The present invention relates to a method of extracting a call set-up failure probability and a premature disconnect probability, which are quality factors necessary for the quality control of a data communication network, by using network data. More particularly, the present invention relates to a method of extracting a call set-up failure probability and a premature disconnect probability by using network data which extracts the call set-up failure probability and the premature disconnect probability by using various call information which are included in communication network data. In accordance with the present invention, a method of extracting a call set-up failure probability and a premature disconnect probability which are quality factors necessary for the quality control of a data communication network is provided which comprises the steps of constructing a configuration database from which quality values are extracted and a database storing a cause for a premature disconnect which identifies whether a cause for a premature disconnect is from the communication network or from a subscriber; reading the configuration database and the database storing a cause for a premature disconnect which have been constructed; reading a billing record from communication network data; verifying whether the read billing record is a normal record; returning back to said step of reading a billing record from communication network data if it is determined that the read billing record is not a normal record, and determining whether a call originating/destination number of the billing record is equal to a number stored in the configuration database if it is determined that the read billing record is a normal record; returning back to said step of reading a billing record from communication network data if it is determined that a call originating/destination number of the billing record is not equal to a number stored in the configuration database, and updating the information content of a statistics database previously constructed for each configuration database, each originating/destination call, and each time and date if it is determined that a call originating/destination number of the billing record is equal to a number stored in the configuration database; and calculating the call set-up failure probability and the premature disconnect probability for each configuration database, each originating/destination call, and each time and date from the information content of the statistics database.
