The present invention relates to a mobile communication system equipped with a virtual call signal generation function and a control method thereof. In particular, a virtual call signal generation for generating various types of virtual call signals and verifying the mobile communication system through the generated virtual call signals is provided. The present invention relates to a mobile communication system having a function and a control method thereof.

In general, a mobile wireless communication network refers to a network for the purpose of performing communication between the mobile terminals and between the mobile terminal and the outside of the mobile terminal. The communication network targets a mobile terminal such as location tracking of a mobile terminal, base station setting, and route setting. One unique feature is needed. However, such a mobile communication network processes radio calls transmitted from mobile terminals through a mobile communication system represented by a base station installed in a plurality of areas where the terminal can move. Therefore, such a mobile communication system usually needs to verify whether the mobile communication system can handle outgoing signals normally before being installed in a certain area. Thus, the mobile communication system can be stabilized and the development period can be shortened. It can also reduce the development costs.

Then, referring to FIG. 1 of the conventional mobile communication system, for example, the base station system 70, the operator setting value input unit for inputting the necessary information for generating the virtual signal. 71, a virtual signal generating unit 72 for generating and outputting a virtual signal at a predetermined time interval and the number of occurrences according to the setting value set by the operator setting value input unit 71, and the virtual signal generating unit 72 And a call processing control unit 73 for receiving a virtual call signal message of) and proceeding with call processing to test the system.

Here, the operator set value input unit 71, the virtual call signal generation unit 72, and the call processing control unit 73 are usually provided in the control board 74 of the base station 70.

Meanwhile, referring to the operation of the conventional mobile communication system, for example, the virtual signal generator of the base station system, first, the operator generates the virtual signal from the control board 74 of the mobile communication system, for example, the base station 70. If you want to test the system through the operator input value input unit 71 inputs the information of the virtual signal to be generated on the screen for inputting the terminal information. Here, the information for verifying the mobile communication system includes a protocol revision of the mobile station (MOB_P_REV) for indicating protocol information of a terminal, a SERVICE_OPTION (Requested service option for this origination) for indicating a service required by a terminal, and a terminal request. CH_IND (Channel Indicator) indicating the channel to be used, FOR_RC_PREF (Forward Radio Configuration preference) required by the terminal in the forward direction (terminal to terminal), REVR_RC_PREF (Reverse Radio Configuration preference) required by the terminal in the reverse direction (terminal to base station), terminal There is an EXT_CH_IND (Extended Channel Indicator) for indicating a channel additionally requested. On the other hand, when the operator inputs the desired number of occurrences and generation period of the virtual foot signal through the operator set value input unit 71, the input virtual foot signal information is stored in the database (DB) of the control board (74). Then, the virtual signal generating unit 72 of the control board 74 drives the timer using the generation period input by the user and then generates information on the database to generate the virtual signal when the set time is reached. A virtual call signal is generated by reading from and output to the call processing controller 73. Accordingly, the call processing controller 73 verifies the call signal function of the mobile communication system using the virtual call signal generated by the virtual call signal generation unit 72 and outputs the result.

Here, the virtual signal generation unit 72 compares whether the virtual signal generation number set by the user matches or does not match, and performs the virtual signal generation process again, while the virtual signal generation frequency set by the user is different. If it matches, the virtual signal generation process ends.

However, since the virtual signal generating apparatus of the conventional mobile communication system as described above continuously generates the virtual signal at regular time intervals at the request of the operator, the verification method of the mobile communication system by generating the virtual signal is very limited. In order to generate a variety of virtual outgoing signals, the user must continuously change the input value for generating a virtual outgoing signal. Therefore, the user's convenience is considerably degraded. There was a problem that it takes time.

Accordingly, the present invention has been invented to solve the above-mentioned problems, and the mobile communication system can be operated by precisely checking the state of the mobile communication system in various call signaling environments, thereby maximizing the operation stability of the mobile communication system. It is an object of the present invention to provide a mobile communication system having a virtual call signal generation function and a control method thereof.

In order to achieve the above object, the present invention provides an operator setting for inputting an index distribution function value or an index item value for generating the virtual outgoing signal in a mobile communication base station system for testing outgoing signal through the virtual outgoing signal. A virtual signal generator for generating and outputting a virtual signal in the form of an exponential distribution function or a value selected from an index according to a value input unit, a value set by the operator set value input unit, and virtual transmission of the virtual signal generator Provides a mobile communication system having a virtual call signal generation function including a call processing control unit for receiving a call message and proceeding with call processing to test a system.

If not, the loop return step of generating a virtual firing signal by returning to the virtual firing signal generating step; The virtual end signal generation function consisting of a test termination step of terminating the virtual outgoing signal test of the mobile communication system when the number of generated virtual outgoing signals coincides with the number of occurrences of the virtual outgoing signal set by the user as a result of checking during the occurrence frequency checking step It provides a control method of the provided mobile communication system.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention is set by the operator set value input unit 1 and the operator set value input unit 1 for inputting an index distribution function value or an index item value for generating a virtual call signal as shown in FIG. The virtual signal generating unit 2 and the virtual signal generating unit 2 for generating and outputting a virtual signal generated in the form of an exponential distribution function or a value selected from the index according to a set value are received. And a call processing control unit 3 for proceeding with call processing to test the system.

Here, the operator set value input unit 1, the virtual signal generation unit 2 and the call processing control unit 3 are usually provided in the control board 5 of the base station 4. As shown in FIG.

On the other hand, as an embodiment of the virtual signal generating unit 2 as a DB of the terminal information assigned to the index using the information input by the operator and input and output the terminal information using the index value received from the random value generator DB unit 6 to be made, a random value generation unit 7 which delivers the index generated by using a random function at a predetermined time interval input by the operator to DB unit 6, and the DB ( And a virtual signal generator 8 for generating a virtual signal using the terminal information received from the terminal 6). In addition, another embodiment of the virtual signal generating unit 2 includes a DB for storing the setting data and a timer 9 for checking the setting time.

Here, the exponential distribution function value includes an average virtual signal generation interval value ??, a maximum signal generation interval value max, a minimum signal generation interval value min, and a target signal generation frequency.

Next, a control method applied to the above apparatus will be described.

First, in the method of the present invention, as shown in FIG. 3, the process proceeds to the step S2 of inputting the virtual signal generation value in the initial state S1 and inputs an index distribution function or an index type user input value for generating the virtual signal generation. Take it and save it.

Here, in the inputting the virtual signal generation value (S2), if the user's input is an exponential distribution function, the average virtual signal generation interval value (??), the maximum signal generation interval value (max), and the minimum signal generation interval value (min), and further includes an exponential distribution function input step for receiving and storing the target occurrence signal data. In addition, in the virtual signal generation value input step (S2), if the user's input is in the form of an index, the index information, the number of occurrences, and the generation period for generating the virtual call selected by the user are input and stored in the DB. It further includes an index type input step.

On the other hand, after the virtual signal generation value input step (S2) to proceed to the virtual signal generation step (S3) to generate and move the virtual signal of various forms in accordance with the exponential distribution function type or index type setting value input by the user Verify communication system.

Here, in the virtual firing signal generating step (S3), if the input set value is an exponential distribution function type, a time value is calculated by returning the exponential distribution coded exponential value function using a value set by the user as a parameter. The apparatus further includes an exponential distribution function test step of generating a virtual signal in a maximum and minimum range at the calculated period and testing the mobile communication system.

On the other hand, the virtual firing signal generating step (S3) is a timer driving step for driving the timer by using the virtual firing signal generation period value when the input setting value is in the form of an index, and random function after the timer driving step An index selection step of selecting an index to generate a virtual firing signal by using a method, and after selecting the virtual firing signal information of the selected index after the index selection step, a virtual firing signal is generated using the selected value to test the mobile communication system. It further comprises an index type test step.

On the other hand, after the virtual firing signal generating step (S3) proceeds to the occurrence frequency check step (S4) to check whether the number of the virtual firing signal currently generated coincides with the number of generation of the virtual firing signal set by the user. At this time, if the number of occurrences of the virtual firing signal currently generated does not match the number of occurrences of the virtual firing signal set by the user, as a result of checking the occurrence frequency checking step (S4), the process returns to the previous step (S3) and repeats the loop. However, if the number of occurrences of the virtual generated signal currently generated coincides with the number of occurrences of the virtual generated signal set by the user as a result of checking during the occurrence number checking step (S4), the virtual issued signal test of the mobile communication system is terminated.

In other words, when the operator wants to test the system by generating a virtual signal from the control board 5 of the mobile communication system, for example, the base station 4, the operator inputs the terminal information through the operator set value input unit 1. Input the information of the virtual signal to be generated.

In this case, when the input value is an exponential distribution function, the operator sets an average virtual signal generation interval value (??), a maximum signal generation interval value (Max), and a minimum signal generation interval through the operator setting value input unit 1. The value Min and the number of target signal generations are input to the virtual signal generation unit 2. In addition, the virtual signal generating unit 2 is a parameter for the average virtual signal generation interval value (??), the maximum signal generation interval value (Max), the minimum signal generation interval value (Min) input by the operator as a parameter By assigning the returned value to Time, the Expo_value routine coded by the exponential distribution function is assigned. In addition, the virtual firing signal generating unit 2 is a value in which the general exponential distribution function is returned from the minimum value 0 to the maximum value 6 times the average, so that the value is returned within the operator's desired area in FIG. As shown, Min and Max values are set. At this time, the virtual signal generating unit 2 calls the system call of sleep with the set variable Time as a parameter, and as shown in FIG. 4 by a process executed by the operating system after the time time has elapsed. An outgoing signal is generated in the form of an exponential derivation function and output to the call processing controller 3. Therefore, the call processing controller 3 verifies the call signal function of the mobile communication system using the virtual call signal generated by the virtual call signal generation unit 2 and outputs the result.

Here, the virtual signal generator 2 increases the generated signal count, and then compares the generated number of generated signal input signals with the operator's input signal value, and if the value is different, sets the time parameter again. The system call of sleep is called. If the value is the same, virtual signal generation ends.

On the other hand, when the value input through the operator setting value input unit 1 is an index type, the operator reports the table output as shown in FIG. 5 on the virtual signal selection input screen through the operator setting value input unit 1. Select the Index for the virtual call you want. At this time, in the virtual call signal selection input screen, the user may select only one index to verify the mobile communication system, or select a plurality of indexes to perform the mobile communication system verification. In addition, the user inputs the number and generation period of generating the virtual signal through the operator setting value input unit 1 to the virtual signal generating unit (2). Then, the virtual signal generator 2 stores the index information selected by the user to generate the virtual signal in the DB unit (database 6). The virtual signal generating unit 2 drives the timer 9 by using the generation period input by the user. At this time, the virtual firing signal generating unit 8 of the virtual firing signal generating unit 2 receives the virtual firing signal selected by the user using a random function of the random value generating unit 7 when the operation of the timer 9 stops. The index to be generated is selected by the DB unit 6, and then a virtual call signal is generated using this index information and output to the call processing controller 3. Therefore, the call processing controller 3 verifies the call signal function of the mobile communication system by using the virtual call signal generated by the virtual call signal generator 2 and outputs the result.

On the other hand, the virtual signal generating unit 8 compares the target number of occurrences of the input signal generated by the operator with the generated signal signal count value is not matched if the value is different if the value is different, continues to perform the signal generation process, If the value is the same, virtual signal generation ends.

As described above, the present invention generates various types of virtual call signals and verifies the mobile communication system based on the generated virtual call signals, thereby precisely checking the state of the mobile communication system in various call signaling environments to provide a mobile communication system. It can be operated accordingly has the advantage of maximizing the operational stability of the mobile communication system.

In addition, according to the present invention, since the generation of the virtual call signal is generated by using a random function value or an exponential distribution function, the mobile communication system is tested in a virtual situation similar to the various usage environments that the mobile communication system may face. It also has the effect of significantly improving the test functionality of the communication system.
