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

FIG. 1 is a block diagram of a mobile communication system for blocking a spam phone according to an embodiment of the present invention. Referring to FIG.

A mobile communication system for blocking a spam phone according to an embodiment of the present invention includes a subscriber registration apparatus 100 and a switching center 300.

The home location register 100 is a mobile subscriber database having a subscriber's terminal information, subscription information, location information, and authentication function in a wireless communication exchange. The subscriber registration device 100 includes a mobile switching center (MSC) and a visitor location registering device (VLR) To control the signaling network protocol SS7 and to perform transactions with the VLR to complete the incoming call and update the subscriber information.

In particular, the subscriber registration device 100 has a function of blocking the spam phone by confirming the telephone number of the caller before the caller is switched, and notifying the receiver of the fact that the spam phone is blocked when the caller using the call forwarding number makes a call can do.

More specifically, the subscriber registration device 100 includes a spem number management unit 110, a service authentication unit 130, a sender code verification unit 150, and a spam phone blocking unit 170.

The spell number management unit 110 stores the number of the spam phone by the user or system administrator of the system according to the present invention. As described later, when it is confirmed that the caller uses the call forwarding code, it is possible to confirm whether or not the call is a spam phone by using the number of the spam phone stored in the spam number managing unit 110. [

The service authentication unit 130 authenticates whether the receiver is subscribed to the call forward spam blocking service. For example, if the call forwarding spam blocking service is referred to as a service, only a user who has applied for the service and paid a fixed fee, such as a ring back tone service (coloring or peeling service) currently being served, There will be. In this case, by including the information on approval of 'a service' in the user information, the service authentication unit 130 can check whether the receiver is an approved receiver by inquiring the user information when the caller calls.

The sender code verification unit 150 can confirm whether or not the caller's service code includes the caller ID code by checking the service code of the caller. That is, when the caller uses the call forwarding service as needed, it can determine whether the caller is a call forwarding service user by checking the call forwarding code included in the caller's service code. Here, the call forwarding service refers to a service in which a call is made to a general home telephone number or a general mobile communication telephone number when a service provider makes a call to a specific telephone number used in accordance with a business need. Since the service code of the service provider using this call forwarding service will include the call forwarding code, the caller code checking unit 150 can find out whether the caller's service code has the call forwarding code. Such a call forwarding service is often used when a lender or an insurance company makes an advertisement spam call, which causes a receiver to misunderstand the call from an ordinary caller, which is a cause of wasted communication fees and excessive mental stress.

Although not shown in FIG. 1, the service authentication unit 130 and the sender code verification unit 150 are integrally implemented in a predetermined service authentication unit (not shown) to authenticate and authenticate the service to which the receiver and the sender subscribe. May be implemented.

When the caller uses the call forwarding code, the spam phone blocking unit 170 refers to the spam number management unit 110 to check whether the forwarding telephone number is the number of the spam phone. If the originating phone number of the caller is the number of the spam phone stored in the spam number managing unit 110 by the spam phone blocking unit 170, the spam phone blocking unit 170 transmits the phone number of the caller identified as the spam phone Can be blocked.

The mobile switching center 300 provides a circuit switching service to a mobile communication subscriber in cooperation with a fixed network 300. The switching center 300 is a connection point for user traffic between a mobile communication network and a general telephone network, . An additional function of the switching center 300 is to track the location of the mobile subscriber and to provide a mobile phone service at all times and to perform a hand-off function of a call channel to continue the communication service even if the location is changed It is possible.

In particular, when the calling party's phone number is confirmed as a spam phone as a result of confirming the original phone number in the above-described manner, the switching center 300 transmits the position of the mobile phone subscriber, which is an additional function of the switching center 300, Lt; RTI ID = 0.0 > information < / RTI >

When the spam phone is blocked by the spam phone blocking unit 170, the switching center 300 may include a spam phone notification unit 310 for notifying the calling party or the receiver of the fact that the spam phone is blocked. Although it is more meaningful for the recipient to notify the switching center 300 of the fact that the spam phone is blocked, it can be implemented to notify the calling party of the blocking message as needed. Here, the means for informing the switching center 300 of the interruption may be implemented by a text message or a voice message (or an alarm sound).

The spam phone notifying unit 310 is not shown in FIG. 1. However, the spam phone notifying unit 310 may be implemented by being installed in the subscriber registration apparatus 100, unlike the embodiment shown in FIG.

Although not shown in the above description, the subscriber registration apparatus 100 and the switching center 300 may be essential to both the calling party and the receiving party, but in FIG. 1, in the case of the subscriber registration apparatus 100, Those of ordinary skill in the art will recognize that only the exchange center 300 is shown for the calling party.

When a call comes from the sender, the receiver authenticates whether or not the receiver is subscribed to the call forward spam blocking service (S101). The method of authenticating by the service authentication unit 130 has been described with reference to Fig.

It is checked whether the caller's service code includes a call forwarding code (S102). A method for confirming whether or not the caller's code identifying unit 150 includes the call forwarding code among the caller's service codes is the same as that described above with reference to FIG. As a result of checking, if the caller's service code does not include the call forwarding code, normal call connection can be made, but since the order related to the spam phone blocking of FIG. 2 is not related, Respectively.

If the caller's service code includes the call forwarding code, it is checked whether the telephone number of the caller before the call forwarding is the number of the spam phone (S103). Whether or not the spam phone blocking unit 170 confirms whether or not it is the number of a spam phone number stored in a predetermined spam number DB (the spam number management unit 110 in FIG. 1), will be described with reference to FIG. And therefore, the following description will be omitted.

If the telephone number before the call forwarding is the number of the spam phone, the corresponding spam phone is blocked (S104).

When the spam phone is blocked, a message informing that the spam phone is blocked is notified to the sender or the receiver (S105). It has been described above that the form of the message can be implemented as a text message or an alarm sound.

If the telephone number before the call forwarding is the number of the spam phone, the request for location information of the caller's recipient is blocked (S106). The location information request is blocked by the additional function of the switching center 300 as described above.

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 relates to a mobile communication system for blocking a spam phone and a control method thereof, and more particularly, to a mobile communication system for blocking a spam phone when a calling number is forwarded and recognized as a general phone number by a recipient, (Or managed) spam phone, and to control the spam phone.
