That is, the randomization performing unit 320 receives input data for generating a random call (e.g., a type of a call to be applied (for example, A location registration call, an SMS attempt call, etc.), an editing policy to be applied, etc.) to the randomization algorithm to determine at least one parameter for at least one communication call according to the input data, a call origination interval, The call rate between silence, and the order of call combination.

More specifically, when an algorithm for randomizing predetermined parameters (for example, bearer capability parameters) of a communication call is used as the randomization algorithm, the randomization performing unit 320 according to the randomization algorithm, Selects a communication call at random for at least one communication call (e.g., each virtual terminal-corresponding location registration call, SMS attempt call, etc.) according to input data, and creates an abnormal state among the parameters constituting each selected communication call (Eg, bearer capability parameter) that can be used to change the data rate. For example, the randomization performing unit 320 according to the randomization algorithm sets 0 to 16 bytes of a main parameter (e.g., a bearer capability parameter) constituting a selected communication call (e.g., a setup message) The value can be changed at random.

On the other hand, when the random number generation algorithm or the statistical distribution algorithm for changing the call occurrence interval for the communication call is used as the randomization algorithm, the randomization execution unit 320 according to the randomization algorithm (e.g., the random number generation algorithm) Random random numbers corresponding to the number of at least one communication call (e.g., virtual terminal-corresponding location registration call, SMS attempt call, etc.) based on the data. For example, if there are 100 numbers in at least one communication call (e.g., virtual terminal-corresponding location registration call, SMS attempt call, etc.) based on input data, the randomization performing unit 320 adds (E.g., 100) random random numbers (e.g., 2, 5, 30, 8, 67 ...) between a predetermined range (e.g., 1 milisec to 100 milisec). Then, the randomization unit 320 randomly or sequentially generates the generated random number as a call occurrence interval of each of at least one communication call (e.g., each virtual terminal-corresponding location registration call, SMS attempt call, etc.) It is possible to change the call occurrence interval for each communication call corresponding to each virtual terminal.

In addition, when a statistical distribution algorithm for changing a call occurrence interval for a communication call is used as a randomization algorithm, a randomization algorithm (for example, a statistical distribution algorithm - a normal distribution algorithm, an exponential distribution algorithm, The randomization performing unit 320 according to the present embodiment performs a statistical distribution algorithm (e.g., a normal distribution algorithm, an exponential distribution algorithm, and a lognormal distribution algorithm) on the set parameter values for the probability density included in the input data, To generate a probability density of each unit time interval (x) according to the set parameter value, thereby generating a predetermined number of call generation intervals based on the probability density.

That is, when the set parameter value is determined as the input data of the network verification apparatus 300 is selected, the randomization performing unit 320 sets the set parameter value to a normal distribution algorithm, an exponential distribution algorithm, and a log normal distribution algorithm And generates a probability density of each unit time interval (x) according to the set parameter value.

For example, when a normal distribution algorithm is applied as a statistical distribution algorithm corresponding to a randomization algorithm, when the operator selects the input data, the average (μ) is set to 13.3, the variance ({σ} } Is 5, the randomization performing unit 320 calculates the following probability density function f (x) by applying the normal distribution N (13.3, 5) to the normal distribution algorithm to obtain the normal distribution N (X) is a unit time interval (for example, 1 milisec interval) in consideration of a commercial communication network, and a probability density of each unit time interval Yes.)

The randomization unit 320 applies the set parameter values selected by the operator (for example, average (μ) = 13.3 and variance ({σ} ^ {2}) = 5) to the normal distribution algorithm, (13.3, 5) for each unit time interval (x). The randomization performing unit 320 calculates the number of the corresponding unit time intervals x corresponding to the probability density of each unit time interval x based on the probability density of each generated unit time interval x Generating interval. For example, if the probability density of the unit time interval (3 milisec) is 0.005, the randomization performing unit 320 sets the call occurrence interval according to the unit time interval (3 milisec) to the probability density 0.005 (or 0.005 * 500 = 2.5) (e.g., 2 - decimal point discarding).

Accordingly, the randomization performing unit 320 may divide the call occurrence interval, which is generated based on the probability density of each unit time interval (x), with at least one communication call based on the input data (e.g., And the like), the call interval of each communication call corresponding to each virtual terminal can be changed.

Of course, when the operator selects the setting parameter value according to the statistical distribution algorithm, the randomization performing unit 320 also sets the corresponding setting parameter value to the corresponding exponential distribution algorithm or log normal distribution algorithm The probability density of each unit time interval (x) is generated and the call generation interval for each communication call corresponding to each virtual terminal can be changed based on the probability density. Since the exponential distribution and the lognormal distribution are mathematically known statistical distributions, a detailed description will be omitted.

On the other hand, when the random number generation algorithm or the statistical distribution algorithm for changing the call duration to the communication call is used as the randomization algorithm, the randomization performing unit 320 according to the randomization algorithm (e.g., random number generation algorithm) Random random numbers corresponding to the number of at least one communication call (e.g., virtual terminal-corresponding location registration call, SMS attempt call, etc.) based on the data can be generated. For example, if there are 100 numbers in at least one communication call (e.g., virtual terminal-corresponding location registration call, SMS attempt call, etc.) based on input data, the randomization performing unit 320 adds (E.g., 100) random random numbers (e.g., 2, 5, 30, 8, 67 ...) between a predetermined range (e.g., 1 milisec to 100 milisec). The randomization unit 320 randomly or sequentially generates the generated random number as the call duration of each of at least one communication call (e.g., virtual terminal-corresponding location registration call, SMS attempt call, etc.) according to the input data So that the call duration time for each communication call corresponding to each virtual terminal can be changed.

In addition, when a statistical distribution algorithm for changing a call occurrence interval for a communication call is used as a randomization algorithm, a randomization algorithm (for example, a statistical distribution algorithm - a normal distribution algorithm, an exponential distribution algorithm, The randomization performing unit 320 according to the present embodiment performs a statistical distribution algorithm (e.g., a normal distribution algorithm, an exponential distribution algorithm, and a lognormal distribution algorithm) on the set parameter values for the probability density included in the input data, To generate a probability density of each unit time interval (x) according to the set parameter value, thereby generating a predetermined number of call duration times based on the probability density.

That is, when the set parameter value is determined as the input data of the network verification apparatus 300 is selected, the randomization performing unit 320 sets the set parameter value to a normal distribution algorithm, an exponential distribution algorithm, and a log normal distribution algorithm And generates a probability density of each unit time interval (x) according to the set parameter value.

On the other hand, a statistical distribution algorithm (for example, a statistical distribution algorithm - a normal distribution algorithm, an exponential distribution algorithm, and a lognormal distribution algorithm) for changing the call ratio between voice and silence in a call to a communication call is called a randomization algorithm The randomization performing unit 320 according to the randomization algorithm calculates a set parameter value for the probability density included in the input data by using a statistical distribution algorithm (e.g., a normal distribution algorithm, an exponential distribution algorithm, Algorithm) to generate a probability density of each unit time interval (x) according to the set parameter value, thereby generating a call ratio between a predetermined number of voice and silence based on the probability density.
