Description

Method and apparatus for message division transmission of mobile terminal {Method and apparatus for division and transmission of messages in mobile-terminal}

The present invention relates to a method and apparatus for dividing an input content in 79 or 80 byte units when the user inputs more than 80 bytes in transmitting a short message.

Currently, mobile phone service companies set the limit for sending a single short message to 40 characters or less in Korean and 80 characters or less in English.

At present, with the rapid development of communication technology, individuals can send and receive simple messages as well as voice calls with others while moving from any place or from one place to another.

FIG. 3 is a block diagram schematically showing the configuration of a general short message transmission system. In the drawings, reference numerals 1 and 2 denote mobile terminals to be communicated by a person, and 3 denotes positions of a plurality of mobile terminals 1 and 2. Is a base station (BTS) and an exchange that performs transmission and reception of wireless signals to the mobile terminals (1, 2), conversion and encryption / decryption of communication protocols, and 4 and 5 are SMS (Short) to a plurality of base stations. Short Message Service Center (SMSC) and Short Message Application Platform (SMAP) to provide Message Service.

That is, in the short message transmission system having the above configuration, when an arbitrary mobile terminal 1 is in a specific area, the base station 3 having jurisdiction over the area checks for the existence of the corresponding mobile terminal 1, and transmits and receives voice and data. Allows texting. For reference, the present specification does not describe the voice call function because it is not a description of the voice call function of the mobile terminal but a description of the text message transmission function.

When a user of the mobile terminal 1 inputs a text message to send a text message from the mobile terminal 1 to another mobile terminal 2, the mobile terminal 1 transmits each parameter necessary for sending the text message to the mobile communication. To the system 3.

The parameter elements include a recipient address, a teleservice ID, user data, and a callback number.

The mobile communication system 3 receiving the parameter sends data to the SMSC 4 and the SMSC 4 sends data back to the mobile communication system 3 through a series of procedures. The mobile communication system 3 completes the transmission of the complete text message by providing a parameter to the mobile terminal 2 on the receiving side. For reference, SMAP 5 is not described because it is a means for interworking with a web server.

On the other hand, by establishing a communication system such as the above-mentioned text transmission system, the mobile phone service company provides the SMS (Short Message Service) to the user, and limits the amount of transmission to 80 bytes.

Therefore, due to the limited amount, the user is forced to repeat the transmission procedure many times when transmitting a relatively long sentence larger than 80 bytes.

Accordingly, the present invention has been made in view of the above circumstances, and in a mobile terminal capable of transmitting a relatively long text message of more than 80 bytes in a single transmission procedure even when the user inputs a limit exceeding the amount of text. An object of the present invention is to provide a message splitting transmission method and an apparatus thereof.

The text message data is divided / stored / deleted by the microprocessor 25, which will be described later.

Reference numeral 22 is a counter that counts the number of bytes of the message capacity stored in the data storage 21. 23 and 24 are the transmission call storage section 23 and the reception call storage section 24 which store the audio transmission information and the audio reception information, respectively.

Reference numeral 25 denotes a microprocessor for controlling the entire apparatus of the mobile terminal 10, which is a control means necessary for text message transmission, voice call or data transmission and reception.

Next, the operation of the mobile terminal 50 incorporating the message splitting transmission apparatus having the above-described configuration will be described with reference to the flowchart shown in FIG.

First, a user inputs a message content to the mobile terminal 10 to send a text message to the counterpart by the key input of the keypad 19 (ST1). Upon completion of the content input, the character input content is stored in the data storage unit 21 (ST2), and the counter 22 counts the number of bytes of data stored in the data storage unit 21 (ST3).

According to the counting result of the counter 22, the microprocessor 25 issues another execution instruction (ST4). If the counting result is not more than 80 bytes, the transfer procedure is immediately performed (ST). The transmission procedure is described below. When more than 80 bytes are found as a result of counting, the microprocessor 25 determines whether the 80th byte and the 80 + 1th byte of the text message input data form a single character (Hangul is 1 byte for 2 bytes). In addition, different execution commands are issued (ST5).

When the data content of the 80th byte and the data content of the 80 + 1th byte become a pair of characters, the microprocessor 25 drops an instruction to transmit the contents of 1 to 79 bytes (ST6), If the data content and the data content of the 80 + 1th byte are not a pair of characters from each other, a command is sent to transfer data from 1 to 80 bytes (ST6-1).

The message transmission procedure is as follows. Based on the user input, the microprocessor 25 collects each parameter necessary for transmitting the message, and converts and modulates the parameters through the DSP 16 through the baseband converter 13 and the RF signal processor 12. Finally, the antenna 11 is transmitted to the mobile communication system 3 in the form of radio waves.

Parameters required for message transmission are a recipient's number (Destination Address), a service number (Teleservice ID), user data, and a call back number.

ST6, ST6-1 Procedure In the next step, the transmitted data is deleted from the data storage 21 by the microprocessor 25 (ST7). After the step ST7, the counter 22 is cleared to erase the contents counted in the step ST3. Subsequently, the process returns to the step ST3 of counting the number of bytes of data remaining in the data storage unit 21. As can be seen from FIG. 2, the process loops from ST3 to ST8 until the entire message input by the user is transmitted. Will form.

Finally, if there are less than 80 bytes of data left in the data storage unit 21 after looping from ST3 to ST8, all message splitting transmission procedures are completed by immediately performing step ST5-1 in step ST4.

As an embodiment of the method and apparatus for splitting a message, suppose that a user of terminal 1 (1) wants to send a national annunciation clause 1 to a user of terminal 2 (2) by text message.

National Anthem 1 reads: "God bows _ our _ country_ hurray _ Munghwa _ Samcheon-ri _ colorful Gangsan_ Daehan_ people_ Daehan_ length_ preservation of the East Sea and Baekdusan _ dry and worn out. 120 bytes in total. When the user enters the national anthem 1 by using the keypad 19, it is stored in the data storage unit 21, and the counter 22 counts that the input content is 120 bytes. Subsequently, the microprocessor 25 receives a signal from the counter 22 that the input contents exceed 80 bytes, and determines whether the 80th byte and the 81th byte of data constitute one character. In the anthem 1, the two bytes of data of the "hwa" of "Gangganggangsan" are the 80th and 81th bytes, respectively, and the microprocessor 25 issues a command to transmit data from 1 to 79 bytes.

Subsequently, when data from 1 to 79 bytes are transmitted, the transferred data is deleted from the data storage unit 21 and the counter 22 is cleared. Returning to step ST3 again, the data remaining in the data storage unit 21 is counted. Since the 79th byte of the first part of the national anthem is completed, only the existing 80-120th byte data remains in the data storage unit 21. Accordingly, the counter 22 sends the result that the number of bytes of data remaining in the data storage 21 is 41 bytes, that is, 80 bytes or less. As a result, all data remaining in the data storage unit 21 is transmitted.

As described above, the existing mobile terminal requires n operations to transmit a text message of 80 times n bytes, but according to the present invention, all the messages can be transmitted in one operation.
