Description

Method for transmitting short message in mobile communication terminal

The present invention relates to a text message transmission method in a mobile communication terminal, in particular, when a user sends a text message to the phone number stored in the memory of the mobile communication terminal without having to memorize or memorize the phone number of the recipient stored in the mobile communication terminal separately The present invention relates to a method of transmitting a text message in a mobile communication terminal suitable for immediate use.

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 make a voice call with the other party in response to the call. If there is an urgent need to make a call, it is difficult to make a voice call even if the call is made by the other terminal. 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.

On the other hand, as the popularity of mobile communication terminals has become popular, the functions of mobile phones have also been diversified and their performances have also been developed.

Therefore, the recent mobile communication terminal stores the phone number where the user can save the phone number by specifying the name and address, as well as the phone number that the user has recently sent, although it varies depending on the terminal model. Outgoing phone number storage function has a basic level.

In addition, in recent years, a terminal having a calling party number storage function that can store a calling party's telephone number, which is different depending on a wireless communication service provider, is being introduced.

1 is a flowchart illustrating a method of transmitting a text message using the conventional mobile communication terminal.

As shown in the drawing, a method of sending a text message using a conventional mobile communication terminal includes: selecting to write a text message (ST1); Writing a new sentence after selecting and writing the text message (ST2); Directly inputting the other party's telephone number (ST3); Inputting a telephone number to be contacted (ST4); The 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 phone number, and the input of the telephone number to be contacted may be performed in a different order or selectively by the mobile communication terminal manufacturer.

And step (ST4) of inputting the telephone number to be contacted was a system in which a terminal normally displays its own terminal number to press only a confirmation button.

However, the number of the other party to receive the message was forced to enter the number directly, which caused users a lot of inconvenience.

Most mobile phone users in their teens and twenties who are accustomed to using the various storage functions of mobile phones remember only their frequently used phone numbers, and the rest use memory functions.

In these cases, when you enter a text message and then enter the phone number of the other party, you can't remember the phone number and go back to the initial screen of the terminal to check the other's phone number in the memory of the terminal, and then memorize or write down the text message again. I've often had the inconvenience of taking steps to write.

In particular, if you enter a long message, the difficulty of writing it again from the beginning can not be said.

Although the terminal has a function of storing a written text message, the amount of memory allocated to the terminal is small and this causes a lot of attempts to send a text message without knowing that there is no more text message storage space. The problem I was having was the same.

In the case of a terminal for inputting a text message first, the phone number of the other party to receive the text message is also checked, and before the step of selecting a text message writing function (ST1), the phone number stored in the memory of the terminal is checked and memorized or memorized. After that, the inconvenience of having to enter it manually in the step of requesting the input of the other party's phone number was the same.

As such, although the conventional mobile communication terminal is equipped with various phone number storage functions, there is no method that can be utilized when transmitting a text message.

In particular, before selecting a text message writing function, there was no method of searching for a phone number by using a memory search function and immediately inputting it as a recipient's phone number to receive a text message.

Accordingly, the present invention has been proposed to solve the above-mentioned conventional problems, and an object of the present invention is that the user's phone number to be received when a user sends a text message is stored in his or her terminal memory but is not stored. If you do not need to memorize or memo the phone number by checking the memory separately, the mobile terminal provides a text message transmission method that allows you to enter the stored phone number as the recipient's phone number by calling the memory before selecting the text message writing function. It is.
