Description

Apparatus and method for transmitting a short message in portable mobile terminal}

The present invention relates to an apparatus and method for transmitting a short message of a portable mobile terminal, and more particularly, to an apparatus and method for automatically sending a short message of a long content to be transmitted from an originating portable mobile terminal to be transmitted to the receiving portable mobile terminal in reverse order. It is about.

As wireless communication technology has been put into practical use, it has developed competitively with wired communication method that began with telegraph in the middle of the 19th century. Coaxial cable carriers and analog microwave carriers, which represent wireless communications, have been at their peak.

With the rapid development of optical fiber transmission technology, in the land fixed communication field, the wired communication method by the fiber optic cable has overwhelmed the wireless communication method in terms of economy and technicality regardless of the transmission distance.

In the early 1980s, in North America, the service area was divided into hexagonal cells of several Km to several 10Km in diameter, and the same frequency channel was repeatedly used in geographically separated cells, and wireless channel switching between cells was implemented as subscribers moved. The first commercialization of cellular mobile communication systems has made mobile phones a universal service.

In addition, various wireless communication systems have been commercialized in recent years, such as the demand for mobile phones has exploded.

Mobile communication can be viewed as a form of adding mobility to an existing communication service. A type of mobility includes terminal mobility in which a terminal can be freely moved by being released from a subscriber line, and a user moves to an arbitrary terminal. There are user mobility that can communicate, and service mobility that can accommodate not only voice but also data and video by widening a wireless channel by increasing a use frequency band.

With the development of technology, the miniaturization and lightening of mobile phone terminals are rapidly spreading to personal mobile phones (cellular phones, PCS phones; mobile phones).

The phone offers the following services: If the mailbox subscriber cannot receive a call on the cell phone, the caller leaves a message in the mailbox subscriber's voice mailbox or fax mailbox and allows the mailbox subscriber to check the message. Voice Sampling Service), a voice recognition dialing service (Voice) that connects a voice recognition device to a mobile phone system to memorize / register a subscriber's voice and then make a voice call without having to dial the phone number when the subscriber makes a mobile call. Activated Dialing Service), you can receive numbers and text messages (40-50 characters in English, 80 characters in English) or various life information as texts through the screen of your mobile phone. Upon arrival, you will be notified by mobile phone. Give provide such SMS (Short Message Service).

The emergence of mobile phones has led to the emergence of various types of portable devices that perform similar functions. Among them, portable devices capable of text recognition called PDA (Personal Digital Assistant) are in the spotlight.

The PDA is a device that can perform information collection, storage, creation, retrieval and communication functions, and can easily interface various applications through the pen.

PDAs are equipped with a variety of software and peripherals based on the computer's basic CPU, memory, operating system, and operating system.

A PDA generally refers to a small computer that uses a pen to enter, but is also used in various terms. For example, Palm Computing's Palm and other similar types of personal digital devices are called PDAs. Pens without keyboards are used in products using Microsoft's Windows CE operating system. Devices that use the same Windows CE operating system as Palm-Sizes PC (PPC), but products that use a keyboard are called HPC (Handheld PC). Currently, the term "PDA" is used to encompass all of these concepts.

On the other hand, the PDA can accommodate most services provided in the mobile phone, among which the short message service belongs to the service providing category.

However, when a predetermined short message is sent to an arbitrary party using a mobile phone or PDA, if the amount of short message inputted by the caller (for example, the number of characters) is within the allowed number of characters (for example, 40 to 50 characters). The mobile phone or PDA transmits the short message at once, but if the amount of short message is larger than the allowed number of characters, the caller is required to send the short message directly due to the limitation of the application program in the mobile phone or PDA. There is a hassle to cut and send.

The present invention has been made to solve the above-mentioned problems, and provides a short message transmission apparatus of a portable mobile terminal to automatically fragment and send a short message of a long content in an outgoing portable mobile terminal without the help of a user. Has its purpose.

Another object of the present invention is to provide a method for transmitting a short message of a portable mobile terminal to automatically fragment and send a short message of a long content in an outgoing portable mobile terminal without user's help.

Hereinafter, an apparatus and a method for transmitting a short message of a portable mobile terminal according to an embodiment of the present invention will be described with reference to the accompanying drawings. In the following description of the embodiments of the present invention, the present invention is described by applying the present invention to a portable mobile terminal capable of character recognition called a PDA.

1 is a block diagram of an apparatus for transmitting a short message in a character recognition mobile terminal to which the present invention is applied, and includes a character input unit 10 capable of inputting various characters and a display unit for displaying characters input from the character input unit 10 ( A touch screen 5 with 12); Intrinsic feature data representing the characteristics of Hangul, for example, a character database 14 in which intrinsic coordinate data and stroke data corresponding to each character and scanning data obtained by scanning and standardizing each character are registered; Output coordinate value signal and stroke number of the touch screen 5 generated when a character is input by direct character input on the touch screen 5 using a pen or a character keypad (not shown) operation on the touch screen 5. A touch signal receiver 16 which receives a value signal (analog signal), converts the data into digital data, and outputs the digital signal; If the character input to the character input unit 10 is a character written by a pen, the feature data is generated based on the coordinate value and the stroke number value according to the movement path of the pressure points for the character, and is written to the character database 14. Search for the registered unique feature data, detect the same unique feature data within a predetermined range of error with the generated feature data, and output a corresponding character recognition signal, and the character input to the character input unit 10 A character recognition unit 18 for outputting a character recognition signal corresponding to a set of coordinate values based on a touch signal of the corresponding character when the character is input by the keypad touch; A short message processing unit 20 for short texting a character (eg, Korean) input through the text input unit 10 in a short message transmission mode; A short message output buffer 22 which is generated by the short message processing unit 20 and buffers the short message which is blocked into a form suitable for transmission; A short message output unit 22 for outputting a short message block input through the short message output buffer 20; And as the short message transmission mode selection signal is input, temporarily store the characters (characters for short message) input through the character input unit 10 in an internal memory, and calculate the number of characters of the temporarily stored short message. If the specified short message service exceeds the allowed number of characters, the input short message is divided into predetermined blocks based on the number of allowed characters, and the short message output unit inserts an identifier into each of the divided short message blocks. And a control unit 24 for transmitting the short message blocks in the reverse order of the input order.

The character input unit 10 refers to a character direct input area in which a character can be directly input by a keypad or a pen capable of selecting a character of the touch screen 5.

Unique characteristic data of each of the characters stored in the character database 14 are data determined by experimental values.

The character input unit 10 and the display unit 12 occupy a predetermined area on the touch screen 5. The touch screen 5 on which the character input unit 10 and the display unit 12 are located is a device capable of inputting character data, and a resistance plate method for outputting a coordinate value signal and a stroke value signal according to a change in resistance value is used. Or a capacitor plate method for outputting a coordinate value signal and a stroke value signal in accordance with a change in the charge amount value of the capacitor.

The touch screen 5 recognizes characters input from the user, that is, characters input through the character input unit 10 as pressing points according to pressure, and indicates X / Y coordinate value signals and stroke numbers. Outputs a stroke value signal. The coordinate value and the stroke value signal may be generated by changing the X-axis and Y-axis coordinate values of the movement state and pressure state of the pressure point generated when the user inputs text through the text input unit 10 on the touch screen. It serves as a resource of state data to be able to know which character is input based on the coordinate data and how many times a continuous pressure occurs.

In the embodiment of the present invention, the character input in the character input unit 10 has been described as being performed by the touch screen, but when the present invention is applied to a conventional mobile phone, it is a matter of course that can also be performed by a plurality of character input buttons. .

In the character recognition unit 18, the character input unit 10 performs the character recognition operation through the control unit 26 in the case of direct character input by a pen and character input by a character keypad operation. The character recognition operation is performed through the control unit 26 only when the character directly inputs the character into the character direct input area using a pen. In the case of character input by a character keypad operation, the character recognition unit 18 is performed. The controller 26 may perform the character recognition operation without transmitting the signal.

Meanwhile, the controller 26 determines the number of blocks of the short message to be transmitted by dividing the number of characters of the input short message by the number of allowed characters, and divides the input short message according to the number of blocks of the determined short message. do.

In the embodiment of the present invention, a memory is built in the controller 26. The memory may be provided externally.

2 is a flowchart illustrating a method of transmitting a short message in a text recognition mobile terminal to which the present invention is applied.

When the user selects an SMS (Short Message Service) transmission mode using a keypad and a pen provided in a text recognition portable mobile terminal, a corresponding selection signal is input to the controller 26. Accordingly, the control unit 26 converts the current operation mode into an SMS transmission mode capable of transmitting a short message (step S10).

When a user writes a predetermined character (for example, a character) using a pen or a character keypad, the character currently input on the display unit 12 is displayed under the control of the controller 26.

Here, in case of direct letter input by the pen, the output X / Y coordinate value signal and stroke value signal (analog signal) according to the movement path on the touch screen 18 are transmitted to the touch signal receiving unit 16, and the touch signal The receiving unit 16 converts the input analog X / Y coordinate value signal and stroke value signal into a digital form and transmits it to the control unit 26, and the control unit 26 transmits the digital X / Y coordinate value signal. And a stroke value signal to the character recognition unit 18.

The character recognition unit 18 controls the character recognition signal for the currently input character based on the unique characteristic data for each character previously registered in the character database 14 under the control of the control unit 26. 26). As a result, the control unit 26 can recognize what character is currently input. If the character is input by the character keypad, the controller 26 determines which character is the character currently input by the digital X / Y coordinate value signal input through the touch signal receiver 16.

The control unit 26 determines which letter is the currently input character using this method, and calculates the number of the identified character (step S12).

Thereafter, the controller 26 determines whether the calculated number of characters exceeds the allowable number of characters (eg, 50 characters) of the predetermined short message service (step S14).

As a result of the determination, when the calculated number of characters is smaller than the allowed number of characters (“No” in step S14), the controller 26 controls the short message processing unit 20 to make the currently input letters into a short message. The short message is transmitted to the outside by the short message output unit 24 through the short message output buffer 22 (step S16).

On the contrary, when the number of the calculated characters is larger than the allowed characters (“Yes” in step S14), the control unit 26 divides the calculated number of short message characters by the allowed characters and transmits the message block. The number is determined (step S18). For example, if the calculated number of short message characters is 60, the number of blocks of the message to be transmitted is determined to be two.

The control unit 26 divides the input short message letter into blocks according to the determined number of blocks of the transmission message, and transmits the short message character to the short message processing unit 20. For example, when the number of characters allowed for the short message service is 50 and the number of characters for the input short message is 60, the input short message characters may be divided into blocks of two character areas of 1 to 50 and 51 to 60. . Of course, it may alternatively be divided into two parts of letters 1-30, 31-60, or two parts of different shapes.

The short message processing unit 20 creates the content in the short message block to be transmitted using the input short message for each block. The number of short message blocks to be transmitted (i.e., transmission frames) generated by the short message processing unit 20 is two in all of the above cases. Then, the control unit 26 includes an identifier (for example, numbers such as 2-1 and 2-2 or letters such as full speed and subsequent characters) in a predetermined portion of the divided transmission message block (step S20). This is to say that the short message to be transmitted is continuously transmitted. The identifier indicates that the receiving terminal receives several short messages. For example, as illustrated in FIG. 3, the number of blocks of short messages transmitted is three, and in the case of the second short message block transmission, the receiving terminal places the contents of the second short message block at the center of the screen, Full speed ", and" low speed "identifiers are displayed at the bottom of the screen. If there are no more short message blocks to be received subsequently, the last received short message block is displayed at the center of the screen of the receiving terminal, and an identifier such as "full speed", "end" and "end" is displayed at the top of the screen. do.

Several short message blocks to be transmitted by the short message processing unit 20 are stored in the short message output buffer 22 in the reverse order under the control of the control unit 26. For example, suppose that there are three short message blocks to be transmitted, for example, 3-1, 3-2, and 3-3 short message blocks. The short message output buffer 22 stores the short message output buffer 22 in order.

Then, the short message output block to be transmitted is output by the short message output unit 24 outputted in the reverse order (ie, 3-3, 3-2, 3-1) through the short message output buffer 22. (Step S22).

The control unit 26 checks whether all the short messages to be transmitted have been sent and if it is determined that all have been sent ("Yes" in step S24), the operation of the present invention ends.

As described in detail above, according to the present invention, the short message of the long content is automatically fragmented and transmitted in the reverse order in the outgoing portable mobile terminal, so that the user does not need to worry about the number of short messages to be transmitted and the receiving portable mobile terminal. Will be able to identify multiple consecutive short messages more quickly.

On the other hand, the present invention is not limited only to the above-described embodiment, but can be modified and modified within the scope not departing from the gist of the present invention, the technical idea to which such modifications and variations are also applied to the claims Must see
