BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to wireless communications and data processing, and more particularly, to a portable mobile terminal and a mobile communication system for providing fax data to a user and a method of processing fax data using the same.

A facsimile (hereinafter referred to as a 'fax') is a communication method that decomposes still images such as letters, diagrams, and photographs into pixels, converts them into electrical signals, transmits them, and obtains a permanent recording image in the shape of an original picture at the receiving point. it means. In a broad sense, it refers to both simulated and photo-transfer, and in a narrow sense it refers only to simulated transmission. In simulation transfer and picture transfer, the former is the only pixel in black and white, and the latter contains all the hues. The fax terminal divides the original into several scan lines in a certain order, converts the contrast of the original into electrical energy in this scan line order, and modulates it again as necessary to transmit it to a remote output device or another fax terminal. The receiving fax terminal reproduces the original in the reverse order of the above-described procedure, and outputs it using an output device.

Such a fax system has a disadvantage in that a terminal connected to a wired telephone network is necessary despite the advantage of transmitting documents, photos, etc. to a remote terminal through a wired telephone network. Although the terminal is not necessarily a dedicated fax terminal, the terminal should be equipped with a function of receiving fax data and outputting received fax data through a wired communication network such as a multifunction device.

As methods proposed to overcome the limitations of the fax system, a method using a mobile communication system and a method using a personal computer through the Internet can be representative.

The method of sending / receiving a fax document using a personal computer is to create a document using a document writing program installed in a personal computer or a document maker for a fax, and convert the created document into data and transmit it through the Internet. The receiver receiving the transmitted document converts the received document into a form that can be printed using a program, and then outputs it through an output device such as a printer or a monitor to check.

In the case of using a mobile communication system, a method of installing a mailbox server in a wired telephone network connected to a mobile communication system or a mobile communication system and storing fax data in an installed mailbox server has been proposed. In the fax transmission method of a mobile communication system using a mailbox server, when the fax data is transmitted to the user, the user is notified of this via the mobile mobile terminal and stores the transmitted fax data in the installed mailbox server. In order to check the stored fax data, the user provided the number of the terminal that can receive the fax data to the mailbox server or directly connected. The user directly provides a method of receiving fax data by connecting to a mailbox server through a device capable of outputting fax data, a mobile communication system and a wired telephone network connected thereto, and outputting and confirming the received fax data. The method of notifying the terminal number is a method of informing the mailbox server of a terminal capable of receiving fax data so that the mailbox server transmits the fax data to the corresponding number. In this regard, a known technique for transmitting a fax message (application number 10-1999-48998) of a mobile telephone system is to designate a group to which fax data is sent from a user and send data stored on a mailbox server to designated group members. It only shows how.

On the other hand, the conventional facsimile data interface device (application number 10-1997-0054353) of the prior art is to send the fax data received by the car or mobile phone, such as AV (Audio & Video) system or navigation system mounted on the vehicle Output through the output device of the device. In the mailbox service of the above-described mobile phone system, when the fax data is received by the mailbox server, the user may know the reception of the fax data, but the user may not immediately check the fax data. In order to solve the above disadvantages, fax data is received by a mobile communication terminal such as a mobile phone, and the received fax data is provided to a processing apparatus installed in an automobile to restore the received fax data. The restored fax data can be confirmed by the user through the display device of the AV system. In this case, the mobile mobile terminal, i.e., the mobile phone or the car phone only serves to receive the fax data. Although it has the advantage of receiving the fax data, which can only be provided by wire, through wireless communication, and checking the received fax data on the move, it requires a separate interface device installed in the vehicle. Have

As such, the conventional fax system requires a fax terminal directly connected to a wired network, or receives data through a mobile communication terminal to check fax data through a separate processing and output device.

Accordingly, an object of the present invention is to provide a portable mobile terminal, a mobile communication system and a method of processing fax data using the same, which provide fax data to a user.

In order to achieve the above object, a mobile mobile terminal according to an embodiment of the present invention includes a receiving unit for receiving fax data and an identification code for identifying the fax data; An image viewer program for converting the fax data into image data; A memory capable of storing the image data; A display device capable of displaying the image data by the image viewer program; A control unit for recognizing the fax data based on the identification code and executing the image viewer program according to the result to control the memory and the display device; The image viewer program converts the fax data into image data that fits the width or length of the display device resolution.
The control unit disconnects the call channel after the reception of the fax data is completed.
The mobile terminal according to an embodiment of the present invention further includes a data transmission unit including a connection device to enable connection with an external device.
The control unit detects the free space of the memory and determines whether the detected free space is a size that can store the fax data.
The controller controls the receiving unit to store the fax data in the memory when the detected free space is larger than a size required for storing the fax data, and the detected free space is a size required for storing the fax data. If smaller, the receiver is controlled to disconnect the communication channel with the mobile communication system.
According to an aspect of the present invention, there is provided a portable mobile terminal, a mobile communication system, and a method for processing fax data using the same, including generating fax data and an identification code for identification of the fax data using a mobile communication system; Transmitting the identification code together with the fax data using the mobile communication system; Receiving the fax data and the identification code using a portable mobile terminal and storing the fax data in the portable mobile terminal; Converting the fax data into image data corresponding to the width or length of the display device resolution of the portable mobile terminal by an image viewer program in the portable mobile terminal; Displaying the image data on a display device of the portable mobile terminal.

The sending side fax terminal 1 is provided with an input means (not shown) for receiving fax data, and when the fax data is input by the input means, it provides the input fax data to the mobile communication system 3. At this time, the fax data inputted through the wired telephone network 4 or directly connected to the mobile communication system 3 is provided to the portable mobile terminal 5.

The mobile communication system 3 receives the fax data from the sending fax terminal 1 and transmits the fax data to the user's portable mobile terminal 5. The mobile communication system 3 may be a cellular phone-based communication network such as cellular or PCS (hereinafter referred to as "PCS"), a wireless communication network such as Bluetooth or ubiquitous.

The mobile terminal 5 receives the fax data from the mobile communication system 3 and provides the user with the fax data processed and processed by the method described later. In addition, the portable mobile terminal 5 is connected to an outputable external device (not shown) and provides the received fax data to the external device.

2 is a diagram illustrating the portable mobile terminal of FIG. 1.

Referring to FIG. 2, the mobile terminal 5 of the present invention includes a receiving unit 15 for receiving fax data, an image viewer program for converting received fax data into image data, and receiving received fax data and image data. A data memory 16a for storing, a program memory 16b for storing the image viewer program, a data transmitter 17 and a receiver 15 for transmitting image data to an external device, a data memory 16a, a program memory 16b and a control unit 19 for controlling the data transmission unit 17 and executing the image viewer program.

The receiving unit 15 receives the fax data from the mobile communication system 3 under the control of the control unit 19 and provides it to the data memory 16a.

The image viewer program is executed by the control unit 19, and converts the received fax data into image data.

The data memory 16a stores the fax data provided from the receiver 15 and the fax data converted into image data by the image viewer program.

The program memory 16b stores an image viewer program.

The data transmission unit 17 includes a connector or a slot (not shown) for connecting to an external device, forms a data communication channel with the external device, and transmits image data stored in the data memory 16a to the external device.

The controller 19 analyzes the identification code of the signal received by the receiver 15 to determine whether the received signal is fax data, controls the receiver 15 to receive the fax data, and free space in the data memory 16a. Calculates a value, executes an image viewer program, and controls the data transmission unit 17.

3 is a diagram illustrating a fax data processing method of a portable mobile terminal.

Referring to Fig. 3, fax data is input to the sending fax terminal 1. The input fax data is provided to the mobile communication system 3 via a public communication network such as a wired telephone network to which the sending side fax terminal 1 is connected. The fax data provided to the mobile communication system 3 is converted into a signal transmittable by the mobile communication system 3. The converted signal is provided to the portable mobile terminal 5 using the voice or data communication area.

The mobile terminal 5 maintains a reception waiting state for receiving fax data. (S10)

At this time, when the converted signal is provided from the mobile communication system 3 to the portable mobile terminal 5, the portable mobile terminal 5 receives the converted signal to the receiver 15 (S20).

When the converted signal is received, the control unit 19 determines whether the received signal is fax data (S30). Here, the fax data is basically a portable mobile terminal 5 using the voice call area of the mobile communication system 3. Is received in the data communication area.

If it is determined that the received signal is fax data, the control unit 19 causes the speaker of the mobile terminal 5 to be turned off so that the user does not hear a reception sound output through a speaker (not shown) when receiving the fax data. (S41) In addition, the control unit 19 detects the free space of the data memory 16a in order to store the received fax data in the data memory 16a, and the size of the detected free space that can store the fax data. In addition, the controller 19 outputs guide information such as 'receiving fax data' to the display device 18 to inform the user that the user is receiving fax data.

On the other hand, if it is determined that the received signal is not the fax data, it waits to receive the fax data.

When the free space of the data memory 16a is detected and calculated, the controller 19 determines whether the detected and calculated free space is a size capable of storing the fax data (S50).

If it is determined that the calculated free space is a size that can store the fax data, the controller controls the receiver 15 to provide the fax data to the data memory 16a.

On the other hand, if the calculated free space is smaller than the size required for storing the fax data, the control unit 19 controls the receiving unit 15 to disconnect the communication channel with the mobile communication system (S65). The control unit 19 outputs a message such as 'fax data reception impossible' to the display device 18 to inform the user that reception of the fax data has been canceled (S68).

When the reception of the fax data is canceled, the mobile terminal 5 waits to receive new fax data again or to stop receiving the received fax data.

When the fax data is provided to the data memory 16a, the control unit 19 executes an image viewer program stored in the program memory 16b in order to convert the fax data into image data (S70). 19 confirms the resolution of the display device 18 to convert the fax data into image data, and provides the confirmed resolution to the image viewer program (S71). In addition, the control unit 19 returns to the data memory 16a. The provided fax data is converted into a bit string having a predetermined size for processing by the image viewer program or the control unit 19. (S72)

 When the fax data is converted into a bit string, a buffer area (not shown) for temporarily storing the fax data is set in the data memory 16a, and the fax data converted into the bit string is stored in the buffer area. S80)

The fax data stored in the buffer area is converted into image data that can be displayed on the display device 18 by the image viewer program. (S90) At this time, the image data is converted to the width or length of the resolution of the display device 18 during conversion. do. Here, the format of the image data may be a Bit Map Image (BMP), a Joint Photographic Experts Group (JPEG), a Graphic Interchange Format (GIF), a Tag Image File Format (TIF), or the like. In addition, any data format that can be processed by a computer can be applied in the form of image data.

The converted image data is stored in another area of the data memory 16a. (S100)

When reception of the fax data is finished, the controller 19 controls the receiver 15 to terminate communication with the mobile communication system 3 (S110).

When conversion to the image data ends and communication with the mobile communication system 3 ends, the fax data stored in the buffer area is deleted and the buffer area is released. In addition, the speaker is turned on (Turn On). (S120)

When the storage of the image data is finished, the portable mobile terminal 5 waits for user confirmation of the image data or transmission to the external device (S130).

When the user's command is input, the controller 19 determines whether the user's command is an external device transmission of image data (S140).

If the user's command is to transmit the image data to the external device, the controller 19 determines whether the slot or the connector of the data transmitter 17 is connected to the external device (S160).

On the other hand, if the user's command is not an external device transmission of the image data, the controller 19 outputs the image data of the data memory 16a to the display device 18 (S155). The resolution is determined by the horizontal component x the vertical component, and the image data is output to the display device 18 in accordance with any one of the horizontal and vertical components. Here, the size of the transmitted fax data is determined by the width x length, and the size of the fax data and the resolution of the display device 18 are different. As described above, when the size of the fax data and the resolution of the display device 18 are different, when the horizontal component of the resolution, the horizontal length of the fax data, and the vertical component and the vertical length are respectively matched and output to the display device 18, the received fax data is received. It is difficult to check such as distortion and is deformed and output. For this reason, only the horizontal component of the display device 18 and the horizontal length of the fax data are matched, or only the vertical component and vertical length are output to the display device 18. For this reason, the image data is output in accordance with either the horizontal direction or the vertical direction of the display device 18. When outputting in accordance with the resolution in either direction, a portion may not be displayed on the screen, or the portion of the image may not be identified because the display is small. In this case, an undisplayed portion or a portion displayed small by a zooming process or scrolling may be generated. It can be checked by the user.

When the image data is output to the display device 18, the portable mobile terminal 5 waits for reception of new fax data. (S10)

If it is determined that the external device is connected, the controller 19 requests the user to approve the transmission of the image data, and when the user approves the transmission, the controller 19 controls the data transmitter 17 to transmit the image data to the external device. Here, the slot or connector of the data transmission unit 17 is only an example, and the data transmission unit may include a cable and a terminal capable of transmitting image data, a wireless communication port, an optical terminal, and the like.

When the transmission of the image data to the external device is terminated, the portable mobile terminal 5 waits to receive new fax data (S10).

On the other hand, if it is determined that the external device is connected and the external device is not connected to the slot or the connector, the mobile terminal 5 waits until the external device is connected or provides guide information for requesting reconnection to the user. It outputs to the display device 18. (S170)

4A is a diagram illustrating an example of a fax data transmitted to a portable mobile terminal, and FIG. 4B is an example of outputting the fax data of FIG. 4A to the display device 18 when the ratio between the display device and the image data resolution does not match. The figure shown. As shown in FIG. 4, when the resolution ratio between the display device 18 and the image data does not match, it may be difficult for the user to confirm when outputting the image data to the display device 18.

FIG. 4B is an example in which image data having different resolution ratios is output in accordance with the horizontal resolution of the display device 18, and FIG. 4C is an example in which it is output in accordance with the vertical resolution. When outputting in accordance with either the horizontal or vertical resolution as shown in FIGS. 4B and 4C, the image is output without distortion or distortion so that the user can check the image data. In this case, as described above, the non-display portion and the portion displayed small can be confirmed by enlarging or scrolling using the input device of the portable mobile terminal 5.

As described above, the fax combined mobile terminal and the data processing method according to the present invention receive the fax data through wireless communication of the mobile communication system, and store the received fax data directly in the portable mobile terminal. In addition, the stored fax data is converted into an image viewer program stored in the mobile terminal so that the user can check it through the display device of the mobile terminal. As a result, the mobile user can immediately check the received fax data through the portable mobile terminal, and can connect to an external device for output or processing.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the technical spirit of the present invention.
