The present invention relates to a message retrieval method in a mobile communication terminal, and more particularly, to a message retrieval method in a mobile communication terminal capable of retrieving a message not received by a receiver from a text message transmitted by a sender.

Recently, with the rapid growth of mobile communication terminals, various functions of taking pictures with the mobile communication terminal and listening to music or watching movies have been added.

Among these various functions, the most common one is the function of sending and receiving messages. If the user is in a confined space where the user cannot make a call, the user can communicate with the other party through the function of sending and receiving messages, and most users frequently use the message to express what is difficult to express. Doing.

However, there is a problem that the sender suffers from a message sent by mistake because there is no way to recover the message sent incorrectly. Therefore, if there is a method for recovering the message when a request for recovery is sent among the messages transmitted for security, there is a problem in that the information indicating the recovery target message is weak.

The present invention has been proposed to solve the above-mentioned problems, and its purpose is to set a TI indicating that a recovery request message is requested if a recovery request is made from the transmitted messages, and transmit the message to the receiver's terminal before the message is received. If not confirmed to provide a message retrieval method in the mobile terminal to delete the message.

In order to achieve the above object, the present invention selects a message to request recovery from among the transmitted messages and sets a TI (Teleservice ID, hereinafter referred to as 'TI') indicating a recovery request message when requesting recovery. When receiving the message set the first step of transmitting and the TI has a second step of confirming that the recipient read the message before the message is received, and deletes the message if the recipient did not confirm.

 In addition, it is preferable to transmit the contents of the message requested to be retrieved when the TI is set and transmitted, and to search for the same message in the message inbox that is identical to the contents of the message transmitted when the TI is set.

On the other hand, the determination of whether or not the receiver has confirmed the message may be determined whether the message in the message receiving the message having the same content as the TI set message. If the recipient did not confirm the message, the message can be deleted and the recall successful message sent to the sender's terminal. If the recipient confirms the message, the recipient fails to send the recall failed message to the sender's terminal and the sender attempts to retrieve the message. It is also possible to display.

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

1 is a diagram illustrating an internal structure of a mobile communication terminal for explaining a message retrieval method in a mobile communication terminal of the present invention.

As shown in FIG. 1, the mobile communication terminal according to the present invention includes an input unit 101, a memory unit 103, a control unit 105, a wireless circuit unit 107, and a display unit 109.

The input unit 101 may use various elements such as a keypad, a jog shuttle, a point stick, a touch screen, etc., and is used when a user selects a desired function or inputs information.

The memory unit 103 stores programs and data necessary for the operation and status of the mobile communication terminal or the control of the controller 105, and includes various types of erasable programmable read only memory (EPROM), static random access memory (SRAM), and flash memory. The device can be used.

The controller 105 controls the overall state and operation of the mobile communication terminal and may be formed of a microprocessor or a digital signal processor (DSP). In the present invention, the control unit 105 selects a message to request recovery from among the transmitted messages, and if the request is for recovery, sets the TI indicating the recovery message and transmits the message to the receiver's terminal.

The radio circuit unit 107 is a transmission / reception circuit for transmitting and receiving voice and control information to and from the base station wirelessly. Receives a call signal sent by the caller's mobile communication terminal through the antenna and transmits it to the control unit 105 or transmits data stored in the memory unit 103 to the receiver's mobile communication terminal through the antenna. do.

The display unit 109 may be formed of a liquid crystal display (LCD) or the like, and displays the state and operation process of the mobile communication terminal.

Next, a message recovery method will be described with reference to FIG. 2.

2 is a view illustrating operations of a sender's terminal and a receiver's terminal in a message retrieval method in a mobile communication terminal of the present invention.

본 발명은 상기 TI 필드에 미리 정의된 메시지 회수요청 ID 세트(설정)하여 전송함으로써, 상대 단말기에게 해당 메시지 ID를 가진 사용자 데이터(메시지)에 대한 삭제 요청을 할 수 있다. 따라서 상기 메시지 회수 요청 ID는 고유의 ID값으로 미리 정의되어 송신/수신 이동통신단말기 모두 이러한 메시지 회수요청 ID를 알고 있어야 한다. When the sender who has sent the text message selects a message to request retrieval from the message transmitted (S201), the sender's mobile communication terminal sets a TI indicating that the retrieval request message is transmitted to the receiver's terminal ( S203). TI (Teleservice ID) is a communication service identifier through which the counterpart terminal recognizes the recovery request message. On the other hand, when setting and transmitting TI, it is desirable to also transmit the contents of the message requested to be retrieved. Alternatively, only partial contents of the message requested to be retrieved may be transmitted together.
In general, a specific application of a mobile communication terminal can provide various services such as an e-mail arrival alarm service using SMS data. As described above, in order to use the SMS data in a specific application, there should be a parameter that specifies in which application the SMS data is to be used. TI), the mobile communication terminal can recognize which application the currently received SMS data should be serviced through this TI field.
For reference, the SMS data internal field structure is shown below.
<SMS structure internal field structure>

According to the present invention, a message recovery request ID set (set) predefined in the TI field is transmitted (set), so that a request for deletion of user data (message) having the corresponding message ID can be made to the counterpart terminal. Therefore, the message retrieval request ID is previously defined as a unique ID value, so both the transmitting and receiving mobile communication terminals need to know the message retrieval request ID.

When the TI receives the set message (S205), the receiver's mobile communication terminal determines whether the receiver checks the same message as the message specified in the received retrieval request message (S207). The determination of whether or not the receiver has confirmed the message may be determined by whether the message in the message receiver has the same message as the contents of the set message. On the other hand, in the case of sending a set of TI and transmitting only the contents of a part of the requested message, whether the receiver has confirmed the message is determined whether the message including the contents of the set message is in the message receiving box. Can be.

If the receiver did not confirm the message, that is, if the message requested to be retrieved in the message inbox is deleted (S209), the message of success is sent to the sender's terminal (S211). On the other hand, the transmission fee of the recovery success message may be paid by the sender who is the person who requested the recovery.

In addition, if it is determined in step 207 that the receiver has confirmed the message, that is, if there is no message requested for retrieval in the message receiver, a recovery failure message is transmitted to the sender's terminal (S213), and the sender attempts to retrieve the message. (S215). On the other hand, the originating fee of the recovery failure message may be paid by the sender who requests the recovery.

As mentioned above, although this invention was demonstrated using the Example, these Examples are illustrative and not restrictive. Those skilled in the art will appreciate that various modifications and changes can be made without departing from the spirit of the invention.

As described above, according to the present invention, a message retrieval method in a mobile communication terminal is provided. If the receiver sets a TI indicating the recall request message and transmits the message to the receiver's terminal, if the receiver does not confirm the message before the message is received, the message may be deleted by deleting the message.

In addition, there is no additional cost because there is no special change in protocols other than setting a TI indicating a recall request message to retrieve a message.
