The storage unit 210 stores a numerical value generation algorithm for generating an irregular call duration value based on the predetermined input data.

Here, the numerical value generation algorithm stored in the storage unit 210 includes a random number generation algorithm for generating an irregular random number based on predetermined input data, and a random number generation algorithm for generating a random number as a statistical distribution that generates a probability density based on the input data. Distribution algorithm, an exponential distribution algorithm, and a lognormal distribution algorithm. Accordingly, the storage unit 210 may store at least one of a random number generation algorithm, a normal distribution algorithm, an exponential distribution algorithm, and a lognormal distribution algorithm as a numerical generation algorithm.

The numeric value generating unit 220 applies predetermined input data to the numerical value generating algorithm to generate a plurality of arbitrary random call duration values according to the input data.

That is, when the random number generation algorithm is applied as the numerical value generation algorithm of the storage unit 210, the numerical value generation unit 220 generates the random number generated by the operator of the network verification apparatus 200 or in accordance with a preset selection routine To the random number generation algorithm of the storage unit 210 to generate a plurality of arbitrary random numbers according to the input data, thereby generating a plurality of call duration time values.

For example, when the operator selects input data for generating a random number between 1 sec and 100 sec, the numerical value generating unit 220 applies the random number generating algorithm to an arbitrary random number between 1 sec and 100 sec (for example, 2, 5, 30, 8, 67 ...) are randomly generated (for example, 100), and a plurality of random numbers will be generated as call duration time numbers.

When a statistical distribution (for example, a normal distribution algorithm, an exponential distribution algorithm, and a log-normal distribution algorithm) is applied as the numerical value generation algorithm of the storage unit 210, the numerical value generation unit 220 generates a numerical value ), Or when a set parameter value is selected as input data for a probability density according to a predetermined selection routine, the selected set parameter value is compared with a statistical distribution (e.g., a normal distribution algorithm, an exponential distribution algorithm, To generate a plurality of call duration time values by generating a probability density of each unit time interval (x) according to the set parameter value.

That is, when the set parameter value (e.g., average, standard deviation, variance, etc.) is selected as the input data for the probability density by the operator of the network verification apparatus 200, the numerical value generating unit 220 sets the selected set parameter value A normal distribution algorithm, an exponential distribution algorithm, and a lognormal distribution algorithm to generate a probability density of each unit time interval (x) according to the set parameter value.

More specifically, when the predetermined information acquisition event occurs, the information acquiring unit 240 acquires the billing information corresponding to each call processed through the communication network (e.g., the communication network 100) for a predetermined predetermined acquisition time . At this time, the predetermined information acquisition event may be selected by the operator of the network verifying apparatus 200, or may be selected by the operator at a specific time (for example, every day X time, every day X time Y time, Time) elapsed, etc.) may be reached. In addition, the predetermined acquisition time may mean a predetermined time (e.g., 24 hours, 30 days, etc.) by the operator of the network verification apparatus 200. [

Accordingly, the information obtaining unit 240 processes the information through the communication network (e.g., the communication network 100) for the acquisition time (e.g., 24 hours) when the information acquisition event occurs And obtains accounting information corresponding to each call. The information obtaining unit 240 preferably obtains the duration information of each call based on the start time and end time information of the call recorded in the acquired charge information of each call.

The GGSN displays the data call start time in the S-CDR and the G-CDR, which are billing information, respectively, and generates and provides the generated billing information to the billing server.

The information obtaining unit 240 obtains information on each call processed through the communication network 100 from the exchange apparatus in the communication network 100 or from the charging server (not shown) located in another communication network (not shown) It is possible to obtain the corresponding charging information and acquire the duration information of each call based on the start time and the end time information of each call recorded in the acquired charging information of each call

Then, the information obtaining unit 240 derives a set parameter value (e.g., average, standard deviation, variance, and the like for the duration information) as input data for the probability density based on the acquired duration information of each call.

When the statistical distribution (for example, the normal distribution algorithm, the exponential distribution algorithm, and the log-normal distribution algorithm) is applied as the numerical value generation algorithm of the storage unit 210, the numerical value generation unit 220 generates the numerical value (For example, a normal distribution algorithm, an exponential distribution algorithm, and a logarithmic normal distribution algorithm) obtained through the information obtaining unit 240 of each unit By generating the probability density of the time interval (x), a plurality of call duration times may be generated.

That is, when the setting parameter value derived from the duration of each call processed through the actual communication network 100 of the network verification apparatus 200 is derived from the information obtaining unit 240, The set parameter values are applied to at least one of the normal distribution algorithm, the exponential distribution algorithm and the log normal distribution algorithm to generate the probability density of each unit time interval (x) according to the set parameter value. Here, each unit time interval (x) corresponding to the random variable means the call duration time, and it will follow the predetermined unit time such as milisec or sec considering the commercial communication network.

The verification and assurance unit 230 generates a call duration table for a verification call corresponding to each of at least one virtual terminal based on the call duration time value generated by the value generator 220, And generates a verification call corresponding to at least one virtual terminal.

That is, the verification and assertiveness unit 230 generates a call duration table for a verification call corresponding to each of at least one virtual terminal based on a plurality of call duration time values generated in the numerical value generation unit 220. [ In other words, based on the plurality of call duration time values generated by the numerical value generation unit 220, the verification assurance unit 230 determines at least one of the plurality of call duration values corresponding to each of the at least one virtual terminals A call duration table configured by adopting a time value can be generated.

For example, if the random number generator 220 randomly generates a plurality of random numbers (e.g., 100) and generates the random number as a call duration value, the verification assisting unit 230 transmits the random number to each virtual terminal M1 , Random numbers (e.g., 2, 5, 30, 8, 67 ...) randomly generated in the numeric value generating unit 220 corresponding to the numbers You can create the same call duration table 1.
