2 is a diagram schematically illustrating a configuration of a mobile communication terminal 100 according to a first embodiment of the present invention.

The mobile communication terminal 100 includes a receiver 110, a call determination unit 120, a call restriction selector 130, a transmitter 140, a receiver information transmitter 150, and a message storage unit 160.

The receiver 110 is wirelessly connected to the BSC 200 to receive a call transmitted through the MSC 300, and the transmitter 140 is wirelessly connected to the BSC 200 to make a call through the MSC 300. Send.

The call determiner 120 determines whether the call received by the receiver 110 is a call requesting a voice call or an SMS or multimedia message service (MMS) message.

The call restriction unit 130 provides a call restriction setting function so that the user can set or cancel the call restriction, and when the call restriction is set by the user, the call restriction unit 130 can transmit the receiver information message stored in the message storage unit 160. . In addition, the type of the specific call to be called on the basis of the user's selection of the received call is stored. For example, a call requesting a voice call may be restricted and incoming calls corresponding to SMS and MMS may be received. On the other hand, if the call restriction is set by the user, but the user wants to call when the call is received, for example, when the user checks the caller number when the call is received and presses the call button in consideration of the important call, call restriction 130 performs a function of allowing the call to be connected by temporarily canceling the call restriction setting function.

The message storage unit 160 stores a receiver information message informing the caller that the receiver cannot be called when the call restriction is set. The recipient information message stored in the message storage unit 160 may be an SMS or an MMS as a message set and edited by a user.

The receiver information transmitter 150 extracts the receiver information message stored in the message storage unit 160 and transmits it to the sender in the form of text when the call restriction is set. In addition, the receiver information transmission unit 150 further includes a calling number storage unit 151. The receiver information transmitter 150 transmits the receiver information message in text form when the caller's telephone number is a number stored in the caller ID storage unit 151 when the call restriction is set, and stores it in the caller ID storage unit 151. If the number is not assigned, the recipient information message may not be transmitted. Alternatively, if the caller's phone number is a number stored in the caller ID storage unit 151, the receiver information message may not be transmitted. For example, the sender number of the spam text message may be stored in the caller ID storage unit 151, and the receiver information message may not be transmitted with respect to the stored caller ID.

3 is a diagram illustrating a method of providing receiver information performed in the mobile communication terminal 100 according to the first embodiment of the present invention in order.

First, a call received from the caller is received through the receiver 110 of the mobile communication terminal 100 (S110).

The received call determines the call in the call determination unit 120 (S120). For example, it is determined whether the received call is a call requesting a voice call, a short message call, or an MMS call.

Next, the incoming call limiter 130 determines whether the incoming call is received or the incoming call is restricted (S130). That is, the incoming call limiter 130 determines whether the incoming call limit is set by the user, and cancels the incoming call limit function by the user's selection while the call is received even when the incoming call limit is set. Determine whether to connect.

If it is determined that the incoming call restriction unit 130 is not in the incoming call restriction state, a call is formed for a caller's call so that incoming calls are made, and the receiver information message is not transmitted (S135).

On the other hand, when the incoming call limiter 130 determines that the incoming call is restricted, the call setting of the received call is blocked. And the receiver information transmitter 150 checks whether the sender can be provided with the receiver information message (S140). That is, based on the calling number stored in the calling number storage unit 151, it is determined whether the caller is able to receive the receiver information.

When the sender can be provided with the receiver information, the receiver information transmitter 150 extracts the receiver information message stored in the message storage unit 160 and transmits it to the sender in text form (S150).

Here, the recipient information message is a short message composed of text and is transmitted to the sender by the message center 400 (see FIG. 1) through the BSC 200 and the MSC 300.

On the other hand, if the sender is not a recipient who can be provided with the recipient information, for example, the sender of the spam text is terminated without transmitting the recipient information message.

As described above, according to an embodiment of the present invention, the call can be restricted according to the type of the received call. Therefore, when the called party is in the library and the voice call is difficult but SMS or MMS can be received, the receiver sends the receiver information indicating that the called party cannot receive the voice call. And when the SMS and MMS is received from the sender can be called normally.

In addition, it is possible to send a recipient information message that already stores the calling party's calling number and optionally informs the caller of the call restriction, so that the recipient information message may not be sent to, for example, spam text senders who do not need to provide the recipient information. have. Therefore, it is possible to reduce the number of messages sent without meaning.

Next, a message center and receiver information providing method according to a second embodiment of the present invention will be described in detail with reference to FIGS. 4 to 5.

Therefore, the receiver 710, the call decision unit 720, the call restriction unit 730, the transmitter 740 and the call number storage unit 751 is the receiver 110, the call decision unit 120, the incoming call of the first embodiment Since the limiting unit 130, the transmitting unit 140, and the calling number storage unit 151 are the same, detailed description thereof will be omitted.

The call restriction signal transmission unit 750 transmits a signal and a calling number indicating that the call currently received is in the call restriction state, not the receiver information message indicating that the receiver cannot receive the call through the transmission unit 740.

The incoming call restriction signal is transmitted to the message center 800 through the MSC 300 by the BSC 200 wirelessly connected to the mobile communication terminal 700.

5 is a diagram schematically showing the configuration of a message center 800 according to a second embodiment of the present invention.

The message center 800 includes an incoming call restriction signal receiver 820 for receiving a call restriction signal and a calling number transmitted from the mobile communication terminal 700 and a receiver information message manager 810 for managing a receiver information message.

When the message center 800 receives the incoming call restriction signal and the calling number from the mobile communication terminal 700 in the incoming call restriction signal receiving unit 820, the caller information message stored in the recipient information message management unit 810 is called using the calling party number. Send to.

The receiver information message stored in the receiver information message manager 810 may be randomly created and stored by the user. The user may create and store the message in the receiver information message management unit 810 of the message center 800 by using the mobile communication terminal 700, or write the data using a terminal such as a computer and access the specific web server 600 to access the IWF. It may be stored in the receiver information message management unit 810 of the message center 800 through the 500.

6 is a diagram illustrating a method of providing receiver information performed in a message center 800 according to a second embodiment of the present invention in order.

First, the incoming call restriction signal receiving unit 820 of the message center 800 receives the incoming call restriction signal and the calling number transmitted from the mobile communication terminal 700 through the MSC 300. In addition, it acquires the information of the mobile communication terminal 700 that transmitted the incoming call restriction signal (S210).

Next, the mobile communication terminal 700 which transmits the incoming call restriction signal is checked based on the information of the mobile communication terminal 700 which has transmitted the incoming call restriction signal (S220).

Then, the receiver information message management unit 810 is searched for and extracted by the receiver information message registered by the user of the mobile communication terminal 700 which has transmitted the incoming call restriction signal (S230).

The extracted receiver information message is transmitted to the caller based on the calling number received from the mobile communication terminal 700 (S240).

As described above, according to the second exemplary embodiment of the present invention, since the receiver information message can be written using a terminal such as a computer, more various types of receiver information messages including not only SMS but also video, still images, music, etc. can be easily created. have. In addition, since such various types of recipient information messages are not stored in the mobile communication terminal 700 but stored in the receiver information message management unit 810 of the message center 800, the user of the mobile communication terminal 700 may use a mobile communication terminal ( The memory of 700 can be used more efficiently.

Although the preferred embodiment of the present invention has been described in detail above, the present invention is not limited thereto, and various other changes and modifications are possible.

According to the present invention, the receiver can remove the incoming call according to his or her status, and even if the receiver has set the call restriction, the receiver and the sender can connect the receiver information message indicating that the call is restricted. For this reason, unnecessary connection effort can be avoided, thereby reducing the occupancy of the communication channel due to unnecessary use of the mobile communication system.

In addition, the receiver information message may be prepared as a text message or a multimedia message and stored in the mobile communication terminal. Therefore, the receiver information message stored in the mobile communication terminal can be provided to the caller in a simple and inexpensive manner without forming a separate call channel for providing the receiver information.

In addition, according to the present invention, it is possible to selectively set the call restriction according to the type of call, it is possible to use the call restriction more conveniently according to the status of the receiver.

In addition, for a caller who does not need to inform the receiver of the receiver, it is possible not to selectively transmit the receiver information informing the receiver of the receiver, thereby effectively reducing unnecessary message transmission.
