Abstract

PURPOSE: A method for controlling an origination call processing of an illegal subscriber is provided to omit an unnecessary process of performing a registration notification map operation for reckless retransmitted calls of illegal subscribers, thereby simplifying a processing function and reducing unnecessary system load. CONSTITUTION: A VLR inputs an origination subscriber information request from an MSC(S1). The VLR searches subscriber information stored in a self database(S2). The VLR decides whether origination subscriber information is registered in the self database(S3). If so, the VLR decides whether an ESN transmitted from a mobile station is equal to an ESN stored in the database(S4). If so, the VLR searches an authentication reject item of the database and decides whether the origination subscriber information is illegal(S5). If so, the VLR outputs a response rejection for the origination subscriber information request to the MSC(S6).

Description

TRANSMISSION CALL PROCESSING CONTROL METHOD OF LAWLESS SUBSCRIBER}

The present invention relates to a method for controlling an outgoing call processing of an illegal subscriber, and more particularly, to repeat an outgoing call of an illegal subscriber by storing information about an illegal subscriber in a database of a visitor location register when requesting subscriber information in an exchange. The present invention relates to a method for controlling an outgoing call processing of an illegal subscriber, which makes it possible to omit a registration notification map operation procedure between a visitor location register and a home location register during processing.

In the conventional method of controlling outgoing call processing for an illegal subscriber, a visitor location register which receives an InfoOGSetup from an exchange in the outgoing call processing process for an illegal subscriber whose location is not currently registered manages the subscriber information. In order to receive the subscriber information from the home location register, after performing the Registration Notification Map Operation procedure, the home location register is notified that the subscriber is an illegal subscriber. A method has been used that allows the exchange to reject information requests for outgoing subscribers without storing them in the database.

However, when the outgoing call processing for the illegal subscriber is controlled using the conventional method as described above, since the subscriber information request is rejected without storing the subscriber information on the illegal subscriber in the visitor location register, the same illegal If the subscriber keeps trying to redial, the unnecessary registration / notification operation between the visitor locator and the home locator is continuously performed, causing unnecessary load in the entire exchange system. There was this.

Accordingly, the present invention has been made to solve the above-mentioned problems, and an object of the present invention is to omit an unnecessary registration / notification operation (Registration Notification Map Operation) procedure for indiscriminate re-call processing of illegal subscribers. The present invention provides a method for controlling outgoing call processing of an illegal subscriber to reduce unnecessary load of a system.

In order to achieve the above object, the present invention provides a method for controlling an outgoing call processing of an illegal subscriber, comprising: a first step in which a visitor location register receives an outgoing subscriber information request (InfoOGSetup) from an exchange;

A second step of the visitor location register searching for subscriber information stored in its database (DB) using the calling party number as a key;

A third step of determining, by the visitor location register, whether caller information is registered in its database;

A fourth step of determining whether the visitor locator registers whether the ESN uploaded from the mobile station and the ESN stored in the database are the same when the subscriber subscriber information is registered in the third step;

If the ESN from the mobile station and the ESN stored in the database are the same in step 4, the visitor locator searches for an authentication rejection item (AUTH_DENIED) of the database and then determines whether the value is illegal subscriber information. 5 steps; And

When the value retrieved in the fifth step is illegal subscriber information, the visitor location register is configured to output a response to the request of the subscriber information request to the exchange.

Hereinafter, an outgoing call processing control method of an illegal subscriber according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a functional block diagram illustrating a method for controlling an outgoing call processing of an illegal subscriber according to an embodiment of the present invention. The apparatus for controlling outgoing call processing of an illegal subscriber according to an embodiment of the present invention is a mobile station 100. Referring to FIG. , Exchanger 200, visitor location register 300, and home location register 400.

The mobile station 100 is a mobile subscriber device that can be mounted on a vehicle or possessed by a user to terminate a wireless line, and serves to output an outgoing call to the exchange 200.

In addition, the switch 200 is a central part of a mobile communication network that provides exchange functions between mobile communication subscribers, fixed network subscribers such as a mobile communication subscriber and a public telephone switching network, and a comprehensive information communication network. It receives an incoming call and at the same time performs an exchange function of the corresponding call processing. Here, the exchange 200 performs a function of exchanging information with the visitor location register 300 and the home location register 400 storing subscriber information in order to perform the exchange function according to the call request of the subscriber.

In this case, a network connection is made between the mobile station 100 and the switch 200 through a base station and a control station (not shown), and the base station is a call processing and shape information management, statistics and measurement, and faults that are inherent to the existing base station. It is a system that handles functions such as error / error handling, and provides a seamless interface with the control station. A system that performs a function related to paging support and system maintenance, and outputs an outgoing call received through the base station to the switch 200.

In addition, the visitor location register 300 temporarily stores all information about mobile stations 100 existing in a region managed by the visitor location register 300 and uses the information to set up a call by the mobile subscriber. It serves to transmit subscriber information to the exchange 200 for the subscriber information request from the exchange 200.

Here, the subscriber information stored in the database of the visitor location register 300 is continuously modified according to the movement of the mobile station 100, and the data related to the home location register 400 is always kept the same.

The home location register (400) is a system for storing and managing subscriber parameters and location information for all mobile stations 100 registered in its mobile communication network. It registers important data such as additional services, performs a routing function to the called subscriber, and outputs the corresponding subscriber information to the visitor location register 300.

Next, a method for controlling an outgoing call processing of an illegal subscriber according to an embodiment of the present invention using an outgoing call processing control device for an illegal subscriber having the above configuration will be described.

FIG. 2 is an operation flowchart illustrating a method for controlling an outgoing call processing of an illegal subscriber according to an embodiment of the present invention, and FIG. 3 is an ESN and a visitor location register from a mobile station in the method for controlling an outgoing call processing of an illegal subscriber according to FIG. Fig. 4 is a flowchart illustrating a method for controlling outgoing call processing when ESNs are not the same, and Fig. 4 is an outgoing call when outgoing subscriber information is not stored in a database in the outgoing call processing control method for an illegal subscriber according to Fig. An operation flowchart showing a call processing control method.

First, the visitor location register 300 receives a caller information request (InfoOGSetup) from the switch 200 (S1).

Subsequently, the visitor location register 300 searches for subscriber information stored in its database DB using the calling party number as a key (S2).

Then, the visitor location register 300 determines whether or not the subscriber information is registered in its database (S3).

In this case, when the subscriber information is registered in the third step (S3), the visitor location register 300 is stored in the ESN (Electronic Serial Number; It is determined whether the stored ESN is the same (S4).

Subsequently, when the ESN raised from the mobile station 100 and the ESN stored in the database are the same in the fourth step S4, the visitor location register 300 searches for an authentication denial (AUTH_DENIED) item of its database. Then, it is determined whether the value is illegal subscriber information (S5).

If the value retrieved in the fifth step S5 is illegal subscriber information, the visitor location register 300 outputs a response to the caller information request rejection to the exchange 200 (S6).

The operation up to the sixth step (S6) described above is an operation process when the illegal subscriber requests the subscriber information in the state of registering the illegal subscriber, and in this case, an unnecessary registration / notification operation (Registration Notification Map Operation) procedure is performed. It can be seen that it is not performed.

On the other hand, if the value retrieved in the fifth step (S5) is not the illegal subscriber information, the visitor location register 300 recognizes that the calling party subscriber information request is made by the normal subscriber and corresponding subscribers Information is output to the exchanger 200 (S7).

The operation of the seventh step (S7) is an operation process when the normal subscriber requests the subscriber information in the location registration state of the normal subscriber, and even in this case, the registration notification notification operation is not performed. It can be seen.

As shown in FIG. 3, when the ESN raised from the mobile station 100 and the ESN stored in the database are not the same in the fourth step S4, the visitor location register 300 performs an operation at the mobile station 100. After performing the operation procedure of registration / notification to the ESN, the corresponding response signal is received from the home location register (400) (S8).

Subsequently, the visitor location register 300 determines whether the result of the response signal received through the operation procedure of registration / notification with the home location register 400 is a normal subscriber signal (S9).

If the response signal is a normal subscriber signal in the ninth step (S9), the visitor location register 300 updates the ESN to the value raised from the mobile station 100 in the subscriber information of its database and at the same time the corresponding subscriber. After updating to the normal subscriber, the corresponding subscriber information is output to the switch 200 (S10).

At this time, the operations from the eighth step (S8) to the tenth step (S10) shows the operation process when the normal subscriber requests the subscriber information in the position registration state of the illegal subscriber.

On the other hand, if the response signal is not a normal subscriber signal in the ninth step S9, the visitor location register 300 updates the ESN to the value raised from the mobile station 100 in the subscriber information of its database. At the same time, after storing the illegal subscriber information in the authentication rejection item (AUTH_DENIED) of the database, it outputs the rejection of the request for the subscriber information request to the exchange 200 (S11).

The operation of the eleventh step S11 shows an operation process when the illegal subscriber requests the subscriber information in the state of registration of the normal subscriber.

As shown in FIG. 4, when the subscriber information is not registered in the third step S3, the visitor location register 300 performs an operation procedure of registering / notifying the ESN uploaded from the mobile station 100. After performing the corresponding response signal is received from the home location register 400 (S12).

Subsequently, the visitor location register 300 determines whether the result of the response signal received through the operation procedure of registration / notification with the home location register 400 is a normal subscriber signal (S13).

At this time, when the response signal is a normal subscriber signal in the thirteenth step (S13), the visitor location register 300 is the subscriber information received from the mobile station 100 and the subscriber information received from the home location register 400 The subscriber information of the database is stored and the corresponding subscriber information is output to the switch 200 (S14).

Herein, the operations from the twelfth step S12 to the fourteenth step S14 indicate an operation process for an information request when a normal subscriber first registers a location.

On the other hand, if the response signal is not a normal subscriber signal in the thirteenth step (S13), the visitor location register 300 stores the ESN from the mobile station 100 in the database and at the same time deny authentication of the database ( After storing the illegal subscriber information in the AUTH_DENIED) item, it outputs the rejection of the response to the calling party subscriber information request to the switch 200 (S15).

The operation of the fifteenth step S15 illustrates an operation process for an information request when an illegal subscriber first registers a location.

As described above, according to the method for controlling an outgoing call processing of an illegal subscriber according to the present invention, when an outgoing subscriber information request in an exchange is performed, information about an illegal subscriber is stored in a database of a visitor location register, and the repeated outgoing call of an illegal subscriber is repeated. Request for subscriber information from visitor locator generated during indiscriminate re-call processing of illegal subscribers by enabling the user to omit the registration notification map operation procedure between visitor locator and home locator during processing. This not only simplifies the processing function, but also reduces the unnecessary load in the entire exchange system.
