SYSTEM AND METHOD FOR CONTROLLING SPAM CALLS}

The present invention relates to a spam call processing system and method, and more particularly, to a spam call processing system and method for automatically blocking in a system of a mobile communication network of a spam call to be delivered randomly to a mobile subscriber.

Spam is an e-mail message sent randomly to a large number of recipients on the Internet, or a news article published simultaneously in multiple newsgroups. In most cases, such as advertisements or junk mail sent to a large number of unspecified recipients by mail, messages that are undesired and uninterested by the recipient, or that have no bearing on the topic of discussion for each newsgroup. admit.

Unsolicited and unsolicited recipients of e-mails that are sent unilaterally or in large quantities to people with PC communications or Internet IDs are referred to as spam mails or junk mails. Read or process this

Not only does it waste a lot of time, but also causes discomfort with advertising or sensational phrases or images, and also causes unnecessary traffic and wastes resources of communication networks and mail servers.

In particular, in recent years, such spam mails are not limited to e-mails, and users may indiscriminately transmit unwanted advertising or sensational messages by using a short message service (SMS) of a mobile communication terminal, or use '060'. It is a situation that the announcement of the advertising or sensational content by using a voice call as the calling number.

In the former case, mobile carriers have developed various prevention measures and services to block spam-like short messages, but in the latter case, they immediately hang up after ringing to induce a call to missed calls or In order to avoid call forwarding service for a specific station number such as '060', it is necessary to use general phone number, modulate CID (Caller IDentification), or make subdivision serial number using ARS (Automatic Response System) equipment. There are attempts to spam voice calls in a manner such as attempting, and the complaints of subscribers due to spam call calls using wired or wireless telephones are increasing.

In addition, the subscriber checks a specific station number or phone number such as '060' and randomly terminates or rejects a call from an outgoing call that is suspected to be a spam call based on past experience. As the number of calls to the call increases, the call completion rate decreases and the profitability caused by securing the call time is reduced, and the social criticism of receiving a spam call is also a problem.

Therefore, it is time to prevent the damage of subscribers and to prepare a countermeasure for regulating spam callers by blocking spam calls to subscribers of mobile communication service, which is a social problem.

Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to provide a spam call processing system for automatically monitoring and managing a spam call call that is randomly delivered to a mobile subscriber. And a method.

Preferably, when the outgoing information is added to the spam blacklist at a predetermined level or more, the spam call processing unit classifies the outgoing information into a spam block list to block incoming and outgoing call connections.

Preferably, the spam call processing unit determines whether to include in the spam block list when the originating information is provided from a home location register of the mobile communication network, and transmits the result of the determination to the home location register to connect an incoming / outgoing call. It is characterized by blocking the.

In addition, the spam call processing server according to the second aspect of the present invention for achieving the above object, the database unit for receiving and storing the charge information (CDR; Call Detail Record) correspondingly formed according to the termination of the incoming and outgoing call call; A spam determination unit for determining whether the incoming and outgoing call calls meet a predetermined spam call condition, and if the result is a spam call, a list manager for adding and managing the outgoing information to the spam black list and the spam black list. It characterized in that it comprises a monitoring unit for monitoring the call of the origination information included.

Preferably, the spam call processing server further includes a spam blocking unit for blocking an incoming / outgoing call connection by classifying the outgoing information into a spam block list when the outgoing information is added to the spam blacklist at a predetermined level or more. It is characterized by.

Preferably, the spam determination unit determines whether the spam call condition is satisfied through at least one of an abnormal call transfer code value (CFC) and an acoustic code included in the billing information. It is characterized by.

Preferably, the spam call condition is characterized in that it includes whether the call connection between the incoming and outgoing call is normal and whether the incoming and outgoing connection time is less than or equal to a predetermined threshold time.

Preferably, the spam call condition is set for each of at least one or more incoming information corresponding to the originating information, or is set equally to at least one or more incoming information corresponding to the originating information.

Preferably, when the spam call condition is set for at least one or more incoming information corresponding to the outgoing information, the spam call condition may be changed according to a request of the terminal forming the incoming information.

In addition, the spam call processing method according to the third aspect of the present invention for achieving the above object, the switching switching step of forming a corresponding charging information according to the termination of the incoming and outgoing call, the billing information (CDR; Call Detail Record) A charging execution step of receiving and storing the received information in a database for storing the same; a spam determination step of determining whether the incoming and outgoing call call satisfies a preset spam call condition based on the database; And a monitoring step of monitoring subsequent call execution for the originating information after adding to the list.

Preferably, the spam call processing method further includes a spam blocking step of blocking an incoming / outgoing call connection by classifying the outgoing information into a spam block list when the outgoing information is added to the spam blacklist at a predetermined level or more. It is characterized by.

Therefore, in the present invention, as well as spam calls that are randomly delivered to mobile subscribers, outgoing calls with unregistered numbers as called numbers, outgoing calls that continuously attempt to connect to incoming numbers of consecutive numbers with one outgoing number, It is implemented to automatically block outgoing type spam calls, such as outgoing calls that are terminated after a short waiting time, on the system side of the mobile network, increasing traffic, complaints, and privacy caused by the handling of spam call calls. There is an advantage to reduce the time, cost and mental damage to mobile operators and subscribers by preventing infringement.

Hereinafter, a preferred embodiment of a spam call processing system according to the present invention with reference to the accompanying drawings in more detail.

1 is a block diagram of a spam call processing system according to an embodiment of the present invention. As shown in FIG. 1, a spam call processing system includes a source terminal device of a spam execution target that attempts a telephone connection to a mobile subscriber at random, at least one or more destination terminal devices suffering spam damage, and connection or termination of an incoming / outgoing call call. When the incoming and outgoing call is terminated, the exchange unit 100 stores the charge information (CDR; Call Detail Record) from the exchange unit 100 and the exchange unit 100 to form corresponding charge information, and executes the charge. During this process, after determining whether an incoming / outgoing call meets a predetermined spam call condition based on the database, and if the determination result is determined to be a spam call, the outgoing information requesting the incoming / outgoing call is added to the spam blacklist and managed. It includes a spam call processing unit 200 for.

Here, the spam call processing unit 200 not only manages the spam black list, but also repeatedly adds the spam black list to the spam black list at a predetermined level or more, and blocks the outgoing call connection by classifying the outgoing information again into the spam block list. Or, it is preferable to process to go through a separate process, such as going through the authentication process when the incoming and outgoing call connection.

Or, if it is determined that the spam call processing unit 200 is a spam call, the spam call list is not classified as a spam block list according to the result of monitoring the subsequent call connection process, and is immediately classified as a spam block list to execute blocking. It can also be implemented.

In detail, the process of blocking the incoming / outgoing call connection by the spam call processing unit 200 may include a spam black list in which the outgoing information provided when the spam call processing unit 200 is provided from the home location register of the mobile communication network. It is possible to determine whether or not included in the spam block list, and to deliver the result to the home location register to allow the home location register to block incoming and outgoing calls.

2 is a block diagram of the spam call processing unit 200 shown in FIG. As shown in FIG. 2, the spam call processing unit 200 receives a billing information (CDR; Call Detail Record) correspondingly formed according to the termination of an incoming / outgoing call from the exchange of the mobile communication network and stores a database unit for storing the received call detail record (CDR). 210), whether the incoming or outgoing call is a spam or not determining unit 220 for determining whether or not a predetermined spam call condition is met; and if the determined result is a spam call, the outgoing call outgoing call is added to the spam blacklist. And a list manager 230 for managing the data, and a monitoring unit 240 for monitoring whether the execution call for the subsequent call origination information included in the spam black list forms a spam call.

Furthermore, the spam call processing unit 200 blocks the incoming and outgoing call connection by reclassifying the outgoing information corresponding to the spam blacklist when the outgoing information is added to the spam blacklist as a result of the monitoring as a result of the monitoring. It is preferable to further include a portion (250).

Here, the determining of the spam call determines whether one or more of an abnormal call transfer code value (CFC; Call Final Class) and a call code (Acoustic code) included in the billing information transmitted from the exchange meet the spam call condition. It means to set by the parameter to do.

In addition, the spam call condition may be set in various ways, but it may be desirable to include whether the call connection between the incoming and outgoing calls is normally made and whether the incoming and outgoing connection time is less than or equal to a preset threshold time.

For example, the spam call processing unit 200 is provided with the corresponding billing information from the exchange according to the termination of the incoming and outgoing call, and the incoming and outgoing call is made abnormally among the provided billing information. An abnormal call origination call is generated by determining an abnormal call forwarding code value (CFC; Call Final Class) or a call code (e.g., when the call is terminated before the called party answers the incoming call request). You will be checked.

Subsequently, when the spam call processor 200 confirms that an abnormal incoming / outgoing call has been generated, adds outgoing information included in the incoming / outgoing call to the spam blacklist, or when the outgoing information is already added to the spam blacklist. It will additionally count the details that indicate spam calls have occurred.

If the counting count for the spam call occurrence corresponding to the originating information in the spam black list is equal to or greater than the predetermined level (ie, the number accumulated above the threshold for a predetermined period), the outgoing information is reclassified to the spam blocking list. As it proceeds to block the incoming and outgoing call connection executed through the outgoing information.

3 is a flowchart illustrating an operation of the spam call processing system of FIG. 1. As shown in FIG. 3, in the spam call processing method, the first communication terminal that is the spam execution target executes an incoming / outgoing call call (S100).

Subsequently, the exchange unit 100 transmits the incoming call to the second communication terminal device which is the corresponding called terminal in response to the incoming call request (S102), and receives a response to the incoming call from the second communication terminal device. A process for establishing an incoming / outgoing call is executed (S104 and S106).

Here, when the first communication terminal terminates the call immediately in response to the incoming call of the second communication terminal (for example, when the call is terminated within the threshold time of the spam call condition), according to the present invention to be classified as a spam call There is a possibility to be.

Even in this case, the exchange unit 100 forms the charging information due to the call connection (S110), and transfers the charging information thus formed to the spam call processing unit 200 which is the charging server (S112).

Accordingly, the spam call processing unit 200 determines whether or not a predetermined spam call condition is satisfied by determining information such as an abnormal call transfer code value (CFC; Call Final Class) and a call code included in the received billing information. In step S114, the spam call is added to the spam black list to monitor the subsequent call connection of the first communication terminal device (S116).

Furthermore, when the first communication terminal device is added to the spam black list at a predetermined level or more, a process for blocking an incoming / outgoing call connection is performed by classifying the outgoing information for the first communication terminal device into a spam block list.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the present invention as defined by the following claims It can be understood that

The present invention also provides an outgoing call that continuously attempts to connect to incoming calls of consecutive numbers as one outgoing call, as well as spam calls that are randomly delivered to mobile subscribers. It is intended to automatically block outgoing types of spam calls, such as outgoing calls that are terminated after a short outgoing wait time, on the system side of the mobile network. It is an invention with industrial applicability as much as it can be.
