When a user inputs a phone number for a voice call, a corresponding call is received. And transmit it to the exchange 106 through the mobile communication network 104.

In addition, the mobile communication terminal 102 requests, for example, an authentication service such as terminal subscriber authentication, additional service authentication, etc. to the exchange 106 via the wireless communication network 104.

Next, the mobile communication network 104 serves to ensure the mobility of the mobile communication terminal 102, includes a base station and a base station controller, and supports both synchronous and asynchronous. Here, in the case of a synchronous mobile communication network, a base station (BTS) that receives and transmits a radio communication signal of the mobile communication terminal 102, a base station controller (BSC) that controls the base station and performs communication with the switch 106, and the like. In the case of an asynchronous mobile communication network, the node B for receiving and transmitting the radio communication signal of the mobile communication terminal 102, the radio network controller for controlling the node B to perform communication with the switch 106 (RNC) ) May be included. Of course, the mobile communication network 104 includes, but is not limited to, CDMA networks, GSM networks other than W-CDMA networks, and communication networks of all mobile communication systems to be implemented in the future, including the fourth generation.

Next, the exchange 106 performs basic and additional service processing, incoming and outgoing call processing of the subscriber, location registration procedure and handover procedure processing of the mobile communication terminal 102, interworking functions with other networks, and the like. In addition, the ASS (access switching subsystem) for distributed call processing, the INS (interconnection network subsystem) for centralized call processing, the central control subsystem (CCS) for centralizing operation and maintenance, and mobile subscribers It includes a subsystem, such as a location registration subsystem (LRS) that performs the storage and management of information about the.

In addition, when the switching service 106 requests an authentication service from the mobile communication terminal 102 through the mobile communication network 104, the switch 106 interoperates with the visitor location register 108 and the home location register 110.

(HLR, 108) to take the function of temporary storage.

In addition, the home location register (HLR) 110 receives the location information of the mobile communication terminal 102 and performs functions such as registration recognition, registration deletion, and location checking, and the profile information of the mobile communication terminal 102 is stored. It is. Here, the profile information refers to subscribed additional service information such as mobile identification number (MIN), electronic serial number (ESN), international mobile subscriber identify (IMSI), and calling number service.

Meanwhile, when the authentication device 114 receives an authentication request (that is, authentication request traffic) through the gateway 112, the authentication device 114 allocates an authentication process corresponding to the authentication request to the transaction table, and then provides an authentication service for providing an authentication service. If the application traffic has a value that is relatively larger than the preset traffic threshold while performing the application, the number of transaction tables is reduced (that is, adjusted to reduce application traffic) so that authentication is assigned to the transaction table. Perform an authentication application for the process.

In addition, if there is garbage data in the transaction table while performing the authentication application, the authentication device 114 increases the number of transaction tables according to the garbage data to perform the authentication application for the authentication process assigned to the transaction table. do. For example, if the number of garbage data is five, the number of transaction tables can be increased, for example, by five, to perform the authentication application for the authentication process assigned to the transaction table. The adjustment may be performed through at least one of adjustment through comparison with a value and adjustment on whether garbage data exists.

Next, when the authentication request traffic is received in the mobile communication system having the above-described configuration, the authentication process corresponding to the authentication request traffic is allocated to the transaction table, and the preset authentication process is performed while executing the authentication application for the authentication process assigned to the transaction table. An authentication apparatus for performing an authentication application by adjusting the number of transaction tables through at least one of a comparison with a traffic threshold and a check for garbage data existence will be described.

2 is a block diagram of an authentication device suitable for performing an authentication application by adjusting the number of transaction tables according to an embodiment of the present invention, wherein the authentication device 114 includes a transaction processing unit 202, an application unit 204, and traffic. The controller 206 may be included.

Referring to FIG. 2, the transaction processing unit 202 includes, for example, a transaction capabilities application part (TCAP), and the like. When the authentication request traffic is received through the gateway 112, the transaction is performed. An authentication process corresponding to the corresponding authentication request traffic is assigned to the table, and the transaction table to which the authentication process is assigned is transferred to the application unit 204.

In addition, the transaction processing unit 202 increases or decreases the number of transaction tables when the adjustment control signal for increasing or decreasing the number of transaction tables is provided from the traffic control unit 206.

Next, the application unit 204 includes various authentication applications for providing an authentication service, and performs an authentication application for an authentication process assigned to a transaction table transferred from the transaction processing unit 202.

Meanwhile, the traffic controller 206 continuously monitors and checks (ie, the transaction utilization rate) while the authentication application is being executed in the application unit 204 according to the transaction table of the transaction processing unit 202, and thus the application traffic is preset traffic. If the value is relatively larger than the threshold value, the transaction control unit 202 provides an adjustment control signal for reducing the corresponding transaction table number according to application traffic, and checks whether there is garbage data in the transaction table, and if there is garbage data. The transaction control unit 202 provides an adjustment control signal for increasing the corresponding transaction table number according to the number of data.

Therefore, while performing the authentication application in the authentication device, the overload condition of the application is not generated by adjusting the number of transaction tables according to at least one of the comparison between the traffic of the application and a preset traffic threshold and the presence or absence of garbage data in the transaction table. It is possible to effectively provide the authentication service by preventing it.

Next, when the authentication request traffic is received in the mobile communication system as described above, the authentication process is performed by assigning an authentication process to a transaction table, and when the application traffic has a relatively larger value than the preset traffic threshold, the transaction is performed. The process of performing the authentication application by reducing the number of tables will be described.

3 is a flowchart illustrating a process of performing an authentication application by adjusting a transaction table by comparing traffic of an application with a preset traffic threshold according to an embodiment of the present invention.

Referring to FIG. 3, in the standby mode of the mobile communication system (step 302), the mobile communication terminal 102 performs an authentication service such as, for example, terminal subscriber authentication and additional service authentication through the mobile communication network 104. 106, the exchange 106 in conjunction with the visitor location register 108 and the home location register 110 in accordance with the terminal information corresponding to the corresponding mobile communication terminal 102 through the gateway 112 authentication device ( It is checked whether an authentication request (i.e., authentication request traffic) is received by the authentication apparatus 114 through a process such as requesting an authentication for the mobile communication terminal 102 at 114 (step 304).

As a result of the check in the step 304, if an authentication request is received, the transaction processing unit 202 of the authentication device 114 receives the corresponding authentication request traffic, and then executes the authentication process corresponding to the received authentication request traffic. (Step 306).

When the transaction processing unit 202 transfers the transaction table assigned with the authentication process to the application unit 204, the application unit 204 performs an authentication application for the authentication process assigned to the transaction table (step 308). .

Meanwhile, the traffic controller 206 continuously monitors and checks the transaction processing unit 202 and the application unit 204 (that is, continuously checks the transaction utilization rate) so that the application traffic according to the authentication application execution exceeds the preset traffic threshold. Is checked (ie, has a relatively larger value) (step 310).

As a result of the check in step 310, if the application traffic exceeds a predetermined traffic threshold, the traffic control unit 206 provides the transaction processing unit 202 with an adjustment control signal for reducing the number of transaction tables. The processing unit 202 decreases and adjusts the number of transaction tables (step 312).

For example, the number of transaction tables may be configured, for example, 8000. For example, if the application traffic has a relatively higher value than the preset traffic threshold, the number of transaction tables may be used to prevent the occurrence of an application overload condition. For example, by reducing the number of transaction tables delivered to the application unit 204 by adjusting the number from 8000 to 4000 and from 4000 to 2000, service overload can be prevented by preventing overload due to application traffic during the execution of the authentication application. Can be.

Subsequently, after the authentication apparatus 114 checks whether the execution of the authentication application is completed (step 314), when the authentication application is completed, the authentication information corresponding thereto is transmitted to the exchange 106 through the gateway 112, The exchange 106 stores the authentication information as authentication information corresponding to the mobile communication terminal 102 and transmits the authentication information to the mobile communication terminal 102 through the mobile communication network 104 to complete the authentication process.

Therefore, when the application traffic has a value that is relatively larger than the preset traffic threshold, the number of transaction tables is reduced to perform the authentication application, thereby effectively preventing the occurrence of an overload condition due to the application traffic, thereby effectively providing the authentication service. Can be.

Next, when the authentication request traffic is received in the mobile communication system as described above, the authentication application is performed by assigning an authentication process to the transaction table, and if there is garbage data in the transaction table, the authentication application is increased by increasing the number of transaction tables. Describe the process to be performed.

4 is a flowchart illustrating a process of performing an authentication application by adjusting a transaction table according to the presence of garbage data in a transaction table according to another embodiment of the present invention.

Referring to FIG. 4, in the standby mode of the mobile communication system (step 402), the mobile communication terminal 102 performs, for example, authentication services such as terminal subscriber authentication and additional service authentication through the mobile communication network 104. 106, the exchange 106 in conjunction with the visitor location register 108 and the home location register 110 in accordance with the terminal information corresponding to the corresponding mobile communication terminal 102 through the gateway 112 authentication device ( It is checked whether an authentication request (i.e., authentication request traffic) is received by the authentication apparatus 114 through a process such as requesting an authentication for the mobile communication terminal 102 at 114 (step 404).

As a result of the check in step 404, if an authentication request is received, the transaction processing unit 202 of the authentication device 114 receives the corresponding authentication request traffic, and then executes an authentication process corresponding to the received authentication request traffic. (Step 406).

When the transaction processing unit 202 transfers the transaction table assigned with the authentication process to the application unit 204, the application unit 204 performs an authentication application for the authentication process assigned to the transaction table (step 408). .

Meanwhile, the traffic controller 206 continuously monitors and checks the transaction processing unit 202 and the application unit 204 (that is, continuously checks the transaction utilization rate) to check whether or not garbage data exists in the transaction table (step). 410).

As a result of the check in step 310, if there is garbage data in the transaction table, the traffic controller 206 provides the transaction processor 202 with an adjustment control signal for increasing the number of transaction tables according to the garbage data. The transaction processing unit 202 increases and adjusts the number of transaction tables (step 412).

For example, the number of transaction tables may be configured, for example, 8000. Since there is garbage data in the transaction table in performing the authentication process, authentication is performed because it always occupies the resources allocated to perform the authentication process. In order to prevent the application from running effectively, if there are 1055 garbage data, the number of transaction tables is increased to 9055, for example, by the number of garbage data. By preventing overload, service down can be prevented in advance.

Subsequently, after the authentication apparatus 114 checks whether the execution of the authentication application is completed (step 414), when the authentication application is completed, the authentication information corresponding thereto is transmitted to the exchange 106 through the gateway 112, The exchange 106 stores the authentication information as authentication information corresponding to the mobile communication terminal 102 and transmits the authentication information to the mobile communication terminal 102 through the mobile communication network 104 to complete the authentication process.

Therefore, when there is garbage data in the transaction table, by increasing the number of transaction tables to perform the authentication application, it is possible to effectively prevent the occurrence of an overload condition due to application traffic, thereby effectively providing the authentication service.

Meanwhile, as described above, in an embodiment of the present invention and another embodiment of the present invention, an authentication application is performed by increasing or decreasing the number of transaction tables according to the comparison between the traffic of the application and a preset traffic threshold value and the presence or absence of garbage data in the transaction table. Although the description has been made as to perform the transaction, the authentication is performed by adjusting the number of transaction tables according to at least one of the comparison between the traffic of the application and the preset traffic threshold and the presence or absence of garbage data in the transaction table, that is, considering both conditions. Of course, you can run the application.

For example, the number of transaction tables may be configured, for example, 8000. For example, if the application traffic has a relatively higher value than the preset traffic threshold, the number of transaction tables may be used to prevent the occurrence of an application overload condition. For example, if the number of garbage tables is reduced from 8000 to 4000, and 5055 garbage data exists, for example, the number of transaction tables is increased by 5055, for example, the number of transaction tables is increased. By adjusting the number, the service down can be prevented by preventing the overload caused by the application traffic during the execution of the authentication application.

In the foregoing description, various embodiments of the present invention have been described and described. However, the present invention is not necessarily limited thereto, and a person having ordinary skill in the art to which the present invention pertains can make various changes without departing from the technical spirit of the present invention. It will be readily appreciated that branch substitutions, modifications and variations are possible.

The present invention provides an authentication service by preventing the occurrence of an overload of an application when performing an authentication application, thereby preventing authentication errors, service delays, etc. due to the down of the authentication service. It is possible to reduce the human and human costs, thereby providing a smooth authentication service to the user.
