1 and 2, when the mobile communication terminal 10 transmits a short message, the short message is sent to the mobile switching center 30 through the base station 20. The mobile switching center 30 notifies the mobile communication terminal 10 of the reception of the short message, and transmits the received short message to the short message service center server 40 (S20). Information about the receiving terminal 90 called by the calling mobile terminal 10 is obtained from the HLR (Home Location Register) 60, and the short message is delivered.

The short message service center 40 described above is connected to the mobile switching center 30 and the other mobile switching center 70 to which the receiving terminal 90 belongs, a public switching network or a comprehensive information communication network, and the like. Is stored in the database 50 in digital form and transmitted to the other side.

At this time, when a request for canceling transmission of the short message transmitted from the calling mobile terminal 10 to the receiving mobile terminal 90 is input to the short message service center 40 (S21), the short message service center The server 40 determines whether the short message requested to be canceled from the calling mobile terminal 10 has been transmitted to the receiving mobile terminal 90 (S22), and the short message requested to be canceled has already been moved to the receiving side. If it is transmitted to the communication terminal 90, and transmits a message that can not be canceled to the calling mobile terminal 10 (S23).

On the other hand, only when the short message requested to be canceled has not yet been transmitted to the receiving mobile terminal 90, the short message stored in the database 50 is deleted (S24) to transmit to the receiving mobile terminal 90. Cancel and transmit a transmission cancellation completion message for the short message requested to cancel the transmission to the calling mobile terminal 10 (S25).

Accordingly, the user of the calling mobile terminal 10 creates a new short message and retransmits it to the receiving mobile terminal 90 (S26).

As described above, the structure of the mobile communication terminal for transmitting the short message transmission cancel signal to the short message service center is as shown in FIG. 3.

3 is a block diagram of a mobile communication terminal according to the present invention.

As illustrated in FIG. 3, the control unit 11 of the mobile communication terminal 10 for transmitting a short message transmission cancel signal includes a mobile station modem (MSM) to control general operations of the mobile communication terminal 10. Storing the transmission time of the short message transmitted from the mobile communication terminal 10 and the telephone number of the receiving mobile communication terminal 90 in the storage unit 12 and storing the received mobile communication terminal in the storage unit 12 ( 90) converts the telephone number or the short message transmission time into a short message transmission cancel request signal and transmits the short message to the short message service center 40.

The storage unit 12 stores a predetermined program that controls the overall operation of the mobile communication terminal 10, and stores data input and output during processing of the program and various data processed.

In addition, the storage unit 12 stores the transmission time of the short message stored by the control unit 11 and the telephone number of the receiving mobile communication terminal 90.

The duplexer 13 communicates with the base station through the antenna ANT to transmit a signal from the transmitting unit 15 to the base station through the antenna, and to receive a signal from the base station through the antenna to the receiving unit 14. .

The receiving unit 14 is controlled by the control unit 11 and receives a radio signal output from the duplexer 13.

The transmitter 15 transmits the modulated radio signal from the audio unit 16 to the duplexer 13.

The audio unit 16 is controlled by the control unit 11, modulates the voice signal input through the microphone (MIC) into a wireless signal, demodulates the wireless signal received through the receiver 14 to the speaker (SPK) The audio signal is sent to the camera.

In addition, when a ring signal is generated from the base station, the audio unit 16 detects the ring signal through the receiving unit 14 and transmits the ring signal through the ringer. Accordingly, the user acoustically confirms that a ring signal is generated from the base station.

The key input unit 17 generates a content input of the short message to be transmitted by the user or outputs a transmission cancel signal of the transmitted short message to the control unit 11, and the display unit 18 is controlled by the control unit 11.

The method of transmitting the short message transmission cancel request signal to the short message service center (SMSC) using the mobile communication terminal will be described in detail with reference to FIG. 3 as follows.

4 is a flowchart illustrating a process of canceling a short message transmission method according to the present invention.

As shown in FIG. 4, in a method of canceling a transmission of a short message transmitted from a mobile communication terminal, first, a user of the calling mobile terminal 10 creates a short message and receives the short message together with the receiving mobile terminal. The phone number of 90 is transmitted to the Short Message System Center (SMSC: SMSC, 40) (S100).

Then, the SMSC server 40 stores the short message transmitted from the mobile communication terminal 10 in the database 50 and retrieves the information of the receiving mobile communication terminal 90 from the HLR 60 (S110). .

Thereafter, the short message transmitted from the calling mobile terminal 10 is transmitted to the receiving mobile terminal 90 using the retrieved information of the receiving mobile terminal 90.

On the other hand, when the transmission cancellation request signal of the short message transmitted from the calling mobile terminal 10 is input to the SMSC server 40 (S120), the SMSC server 40 is a short message requested to cancel the transmission of the receiving mobile communication It is determined whether it is transmitted to the terminal 90 (S140).

Here, the control unit 11 of the originating mobile communication terminal 10 for sending a request for canceling the transmission of the short message to the SMSC server 40 is the receiving mobile terminal 90 stored in the storage unit 12 when the short message is transmitted. After converting to a specific signal value set on the protocol by using the telephone number or the short message transmission time, the converted signal is transmitted to the SMSC server 40.

Then, the SMSC server 40 recognizes the specific signal value set in the protocol as the short message transmission cancel signal and determines whether the short message requested to cancel transmission has been transmitted to the receiving mobile terminal 90.

Subsequently, when it is determined whether the short message requested to be canceled is transmitted to the receiving mobile terminal 90, the SMSC server 40 is not transmitted to the receiving mobile terminal 90. Cancels the transmission of the short message transmitted according to the specific signal value transmitted from the calling mobile terminal 10 (S160).

Thereafter, the transmission cancellation completion message of the short message requested to be transmitted is transmitted to the calling mobile terminal 10 (S170).

On the other hand, if the short message requested to cancel transmission from the calling mobile terminal 10 has already been transmitted to the receiving mobile terminal 90, the SMSC server 40 sends a message indicating that the transmission of the short message cannot be canceled. It transmits to the terminal 10 (S150).

In this way, it is possible to cancel the transmission of the short message that is incorrectly transmitted from the mobile terminal, thereby preventing a part in which misunderstanding of the recipient may occur due to the content of the incorrectly transmitted message.

Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the above-described embodiments, and the present invention is not limited to the above-described embodiments without departing from the spirit of the present invention as claimed in the claims. Various modifications may be made by those skilled in the art, and such modifications are intended to fall within the scope of the appended claims.

According to the present invention described above, by canceling the transmission of the message transmitted from the mobile communication terminal it is possible to prevent the problem of misunderstanding with the receiver due to the transmission of the wrong message.
