Abstract

PURPOSE: A method for transmitting a character message in a mobile communication terminal is provided to store a character message being prepared if a telephone is called when users transmits the character message for preventing the preparing character message from being disappeared and prepare an additional character message when the calling is terminated. CONSTITUTION: A user selects a character preparation menu in a mobile communication terminal(ST11). If a telephone is called when users prepares a character message(ST13), the character message being prepared is stored in a memory(ST14), and the calling is continued(ST15). When the calling is terminated, the stored character message is called, thus the character message is prepared continuously. That is, if a signal for informing a telephone call is received in the mobile communication terminal, the mobile communication terminal recognizes the signal and instructs an automatic storing command. When the stored character message is called(ST17), the user must press a specific button for progressing the next process(ST18). If the character message is completely prepared, the character message is transmitted(ST19).

Description

Method for transmitting short message in mobile communication terminal

The present invention relates to a method of transmitting a text message in a mobile communication terminal, in particular, when a user sends a text message, a text message is stored so that the text message does not disappear when a call comes in the middle, and the text message is continued after the call ends. The present invention relates to a text message transmission method in a mobile communication terminal suitable for writing.

In general, a mobile communication system is a communication system that targets mobile devices such as people, cars, ships, trains, and airplanes, which includes key phone systems, mobile phones (mobile phones, vehicle phones), port phones, aircraft phones, and mobile phones. Trains, cruise ships, express buses), radio calling, radiotelephony, satellite mobile communication, amateur radio, and fishing service ships.

In addition, SMS (Short Message Service) enables voice or text message communication between mobile communication terminals such as Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA), and Personal Communication System (PCS). This service is mainly used when a situation where it is difficult to make a voice call between users.

Here, the situation in which a voice call is difficult means a case where a user of a sending / receiving terminal is in a place where a personal voice phone call is difficult, such as a conference hall. In this case, even if the terminal is called, it is difficult to talk to the other party in response to voice. In addition, if there is an urgent need to make a call, it is difficult to make a voice call even though the terminal has been sent to the other party. You are in trouble.

In this case, the terminal users can contact the terminal user by using a text service to send / receive a text message, but can contact each other about necessary contents.

In addition, a large number of users (teens to thirties) using mobile phones, which are mobile communication terminals, use text messages. Among them, teenagers have the most usage of text messages. The strategy was to target 400 free text messages (018). As time goes by, the utilization rate of text messages will increase.

3 is a flowchart illustrating a text message transmission method in a conventional mobile communication terminal.

As shown therein, step (ST1) of selecting a text message creation; Writing a new sentence after selecting and writing the text message, and inputting a phone number to be contacted with the other party's phone number (ST2 to ST4); A text message including the new sentence and the other party's phone number and the phone number to be contacted is transmitted to the mobile communication terminal of the other party's phone number (ST5).

So, if you choose to write a text message on the phone, write a new sentence, enter the other party's phone number and contact phone number to write a text message.

At this time, the writing of a new sentence, the input of the other party's telephone number, and the input of the telephone number to be contacted may be performed in a different order or selectively for each mobile terminal manufacturer.

However, when a mobile phone user inputs a message when sending a text message, there is a problem in that the message is deleted when the phone comes in the middle and the user must re-enter it from the beginning. In particular, if you enter a long message, you are in a very difficult situation when the phone comes in and you need to re-enter the message after it is deleted.

In order to eliminate this inconvenience, some mobile phones have a storage function that can be stored when a call comes in. However, most users are embarrassed when a call comes in. There was a problem that could not be utilized. Even if the message was saved, it was inconvenient to enter the recipient's phone number again.

Accordingly, the present invention has been proposed to solve the above conventional problems, an object of the present invention is to save the text message and write the call so that the text message does not disappear when the user comes in the middle of the call when sending a text message The present invention provides a method for transmitting a text message in a mobile communication terminal which can be subsequently written after the text message is terminated.

The operation of the text message transmission method in the mobile communication terminal according to the present invention configured as described above will be described in detail with reference to the accompanying drawings.

First, FIG. 1 is a block diagram of a text service system in a general mobile communication system.

Thus, when the mobile communication terminal 10 transmits a text message, the text 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 that the text message has been received, and also receives the received text message from the receiving terminal (not shown in the drawing) which the mobile communication terminal 10 calls. To pass.

In addition, the short message service center 40 is connected to the mobile switching center 104, other mobile switching centers not shown, public switching networks or telecommunications networks, etc., and stores the text messages received from one of them in digital form and then to the other. Will be sent.

2 is a block diagram of a mobile communication terminal to which the present invention is applied.

Thus, the controller 11 controls the overall operation of the mobile communication terminal 10. In addition, the control unit 11 stores the text message being written in the memory 12 when a call comes in during the writing of the text message, and when the call is over, a text including a new sentence or a receiving phone number or a calling party number stored in the memory 12 is completed. Control the creation of subsequent messages.

The memory 12 stores a program required by the controller 11, stores data input and output by the controller 11, and stores text message data transmitted from the short message service center 40 in a predetermined area. Save it. When the text message is sent using the memory 12, the text message being written is stored so that the text message does not disappear when a call comes in the middle. The text message stored in the memory 12 can be subsequently written after the call is terminated.

The duplexer 13 communicates with the base station 20 through the antenna ANT, and separates the transmitted / received signals.

The receiver 14 receives a radio signal input through the duplexer 13 under the control of the controller 11. It also receives the radio signal separated by the duplexer 13, and amplifies, filters and outputs the weak signal.

Under the control of the controller 11, the transmitter 15 filters and amplifies a radio signal output from the audio unit 16 to be transmitted through the antenna ANT through the duplexer 13.

The audio unit 16 modulates the voice signal input through the microphone MIC into a wireless signal under the control of the control unit 11, and demodulates the wireless signal received through the receiver 14 to voice the speaker SP. Send by signal. In addition, when a ring signal is generated from the base station 20, the ring unit detects the ring signal and transmits the ring signal through a ringer.

The key input unit 17 is provided with a plurality of key input buttons. Thus, when the user presses a key, the corresponding key data is generated and transmitted to the control unit 11. Then, the control unit 11 can determine which key value has been pressed.

The display unit 18 includes a liquid crystal display for displaying various kinds of information. The controller 11 is controlled by the controller 11 and receives and displays key data generated by the key input unit 17 and various information signals of the controller 11.

4 is a flowchart illustrating a text message transmission method in a mobile communication terminal according to the present invention.

Therefore, in the first step, the user selects a text message writing menu in the mobile communication terminal 10.

Then, in the second step, when the text message is created, the incoming text message is stored in the memory 12 and the call can be made. When the call is terminated, the text message being written stored in the memory 12 is called to allow the text message to be continuously written. So the process you have done so far is automatically stored on your phone. That is, when the mobile communication terminal 10 receives a signal that a call has been received, the mobile communication terminal 10 recognizes the signal and issues an autosave command. This will automatically save the text message creation process you have done so far. In addition, when the text message being written in the memory is loaded, the user may press a specific button of the key input unit 17 so that the subsequent process may proceed.

In the third step, when the text message is created, the completed text message is transmitted.

In addition, a method of sending a text message is different for each type of mobile communication terminal 10. Some mobile communication terminals 10 may first write a new sentence in a text message, and then enter a receiving phone number and a sending phone number, and the other mobile communication terminal 10 may call a receiver and a sender first of the text messages. After entering a number, a new sentence is sometimes written.

FIG. 5 is a detailed flowchart illustrating the detailed operation of the second step when writing a sentence in FIG. 4 and then inputting a telephone number.

Therefore, it is determined whether a call is received while writing a new sentence among text messages.

When a call comes in while writing a new sentence, the sentence being written is stored in the memory 12 and then the call is made. When the call ends, the written sentence stored in the memory 12 is retrieved from the memory 12 so that the sentence can be continuously written. It also allows you to continue writing sentences if you do not receive a call.

For example, if the perfect sentence you want to send as a text message is "How are you doing?", When the call comes in while entering the incomplete sentence "How are you doing well?" Store in And when the call is over, press the button or automatically to recall the phrase "how are you" stored in the memory (12). Then, in addition to the sentence "how are you" in the text message input menu of the mobile communication terminal 10, the user can complete the contents to be sent by inputting the sentence from thereafter.

When the new sentence is completed, the telephone number is input from the text message, and the telephone is input while the telephone number is input.

When a call comes in during the phone number entry, the completed new sentence and the phone number being entered are stored in the memory 12 and then the call is made. When the call is terminated, the newly completed sentence stored in the memory 12 and the telephone number being input are retrieved from the memory 12 so that the telephone number can be subsequently entered. It also allows you to continue entering a phone number if you do not receive a call.

For example, if you enter a text message and then receive a call while entering the recipient's or sender's phone number, let's say the perfect number you want to enter is "017-123-4567". By the way, when a call comes while inputting up to "017-12", the telephone number "017-12" is stored in the memory 12 together with the new sentence previously entered. When the call is ended, the input sentence and the telephone number " 017-12 " stored in the memory 12 are automatically retrieved from the memory 12 by pressing a specific button or automatically. The user will then be able to enter from thereafter in addition to "017-12".

FIG. 6 is a detailed flowchart illustrating the detailed operation of the second step in the case of writing a sentence after inputting a telephone number in FIG. 4.

Therefore, it is determined whether a call comes while entering a phone number from a text message.

When a phone call is input during the phone number input, the phone number being input is stored in the memory 12 and then the call is performed. When the call ends, the incoming telephone number stored in the memory 12 is retrieved from the memory 12 so that the telephone number can be subsequently entered. It also allows you to continue entering a phone number if you do not receive a call.

For example, if a call comes in while entering the recipient's or sender's phone number, let's say the perfect number you want to enter is "017-123-4567". By the way, when a call comes in while inputting up to "017-12", the telephone number "017-12" is stored in the memory 12. When the call is ended, the telephone number " 017-12 " stored in the memory 12 is automatically retrieved from the memory 12 by pressing a specific button. The user will then be able to enter from thereafter in addition to "017-12".

Also, when the phone number input is completed, new sentence writing is performed in the text message.

And it determines whether a call comes in while writing a new sentence.

When a call comes during writing, the phone number and the sentence being written are stored in the memory 12, and then the call is made. When the call is terminated, the phone number stored in the memory 12 and the sentence being written are retrieved from the memory 12 so that the sentence can be continuously written. If you do not receive a call, continue writing the sentence.

For example, if the perfect sentence you want to send as a text message is "How are you?" Along with the phrase "have a good time" is stored in the memory 12. Then, when the call is finished, the sentence "How are you" with the input or receiving phone number stored in the memory 12 is automatically recalled by pressing a specific button. Then, in addition to the sentence "how are you" in the text message input menu of the mobile communication terminal 10, the user can complete the contents to be sent by inputting the sentence from thereafter.

As described above, the present invention stores the text message that is being written so that the text message does not disappear when a call comes in during the user sends a text message, and then writes the text message after the call ends.

Although the preferred embodiment of the present invention has been described above, the present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. Accordingly, the above description does not limit the scope of the invention as defined by the limitations of the following claims.

As described above, the text message transmission method in the mobile communication terminal according to the present invention stores the text message being written so that the text message does not disappear when the user comes in the middle of the phone when sending a text message and the text after the call is terminated Since the message can be written in succession, a large number of customers no longer have to worry about a call coming in when sending a text message, and the mobile terminal can take advantage of the service.
