The mobile fax system apparatus using the MMS of the present invention is equipped with an application that provides a fax service to perform the self-authentication and secure number registration through the application and to receive the content and the incoming number to be transmitted, the safe number and the content and the called number Receiving a secure number assignment request through the mobile communication terminal 210 and the application to send a message server 230 generates a safe number corresponding to the telephone number of the mobile communication terminal 210 and transmits to the mobile communication terminal 210 Receiving the content received from the message server 230 and the message server 230 for transmitting the registered content and the assured number and called number to the fax server 240 through the MMS service to the intelligent network device 220 and the application Fax server 240 and fax for correcting to meet the standard of the fax terminal 250 on the side and sending to the called number And a fax terminal 250 for receiving content from the server 240.

2 is a block diagram of a mobile fax system using an SMS according to an embodiment of the present invention, Figure 3 is an exemplary view showing an application of a mobile fax system using an SMS service according to an embodiment of the present invention. Next, the mobile fax system and method thereof of the present invention will be described with reference to FIGS. 2 and 3. Mobile communication terminal 210 of the present invention is equipped with an application for providing a fax service. At this time, the application authenticates the user of the mobile communication terminal 210 in the mobile communication terminal 210, registers a security number corresponding to the telephone number of the mobile communication terminal 210, and registers the mobile communication terminal 210. It is a program designed to provide fax service through.

In order to perform a fax service in the mobile communication terminal 210, first, a phone number is input through an application. The mobile communication terminal 210 receiving the telephone number transmits the telephone number to the message server 230, and the message server 230 receiving the telephone number is the actual number of the mobile communication terminal 210 receiving the telephone number and the telephone number. It checks whether or not the phone number matches and transmits the authentication number to the mobile communication terminal 210 through a text message. When the authentication number received from the mobile communication terminal 210 is input into the application, the identity authentication is completed.

This process is to ensure the security by verifying that the user performing the fax service through the mobile communication terminal 210, the message server 230 through the actual phone number and the application of the mobile communication terminal 210 When the input phone numbers match, authentication may be performed through an authentication number, or when a specific character is transmitted to the mobile communication terminal 210, the authentication may be performed by inputting a specific character received by the user into the application. have. The identity authentication method is not limited to the above-mentioned embodiment as a method of commonly used.

When the authentication is completed by entering the authentication number or a specific character, the mobile communication terminal 210 requests the assured number to the intelligent network equipment 220. In this case, the security number refers to a calling number for sending a fax service, that is, a temporary number for preventing the telephone number of the mobile communication terminal 210 from being exposed to the receiving side fax terminal 250 in the present invention. For example, when the phone number of the mobile communication terminal 210 is 010-222-2222, a security number 050-4111-1111 is generated, and a security number 050-4111-1111 is used instead of the number 010-222-2222. It is to be displayed on the receiving fax terminal 250.

The security number may be generated by the intelligent network equipment 220, but may be generated by the fax server 240. When the authentication is completed, when the mobile communication terminal 210 requests the security number to the fax server 240, the fax server 240 generates a security number corresponding to the telephone number of the mobile communication terminal 210 to perform mobile communication. Transmit to terminal 210.

When the intelligent network equipment 220 receiving the security number request generates a security number for the phone number of the mobile communication terminal 210 and transmits the generated security number to the mobile communication terminal 210, the mobile communication terminal 210 attempts to deliver it through a fax service. Register the content. The content may be registered by attaching a file such as a document or a picture or by attaching a picture taken by a camera of the mobile communication terminal 210 directly.

When the content is registered, the mobile communication terminal 210 transmits the registered content, security number, and recipient number to the message server 230 through the mobile communication base station using a multimedia messaging service (MMS). The recipient number may be one or more. In order to transmit the same file to multiple receiving side fax terminals 250, when the recipient numbers of multiple receiving side fax terminals 250 are registered in an application of the mobile communication terminal 210, The registered content is transmitted to each of the fax terminals 250.

When the content, relief number, and recipient number are transmitted to the message server 230 using the MMS, the message server 230 transmits the received content, relief number, and recipient number to the fax server 240. Receiving the content, security number, and recipient number from the message server 230, the fax server 240 corrects the content in accordance with the standard of the fax terminal 250 of the receiver side to correct the contents of the recipient terminal fax terminal corresponding to the recipient number. The corrected content is transmitted at 250. When the content transmitted from the fax server 240 is received by the fax terminal 250 on the receiver side, the fax service of the present invention is completed.

The fax server 240 basically stores the contents for a preset period, and sets the contents to be deleted when a preset period passes or when a forced delete command is input from the mobile communication terminal 210. However, the content may be set to be deleted immediately after the content is received in the fax terminal 250.

In addition, the fax server 240 receives a signal on whether or not to receive the content from the fax terminal 250 and transmits information data on whether the content is received to the mobile communication terminal 210 so that the mobile communication terminal 210 receives the fax terminal. It may be possible to confirm whether or not the content of the 250 is received. If the reception of the content in the fax terminal 250 fails, the fax terminal 250 does not transmit a signal for receiving the content to the fax server 240, or by transmitting a content not received signal, the fax server 240 sends the fax terminal 250. Check whether the content is received. When the fax server 240 confirms that the content has not been received at the fax terminal 250, the fax server 240 transmits a transmission failure signal to the message server 230, and the message server 230 receiving the transmission fails. The message is transmitted to the mobile communication terminal 210 so that the mobile communication terminal 210 can receive the transmission failure message. Alternatively, the fax server 240 may transmit a transmission failure signal to the mobile communication terminal 210 through the Internet network so that the mobile communication terminal 210 may receive the transmission failure message.

When the content reception is successful at the fax terminal 250, when the content reception signal is transmitted from the fax terminal 250 to the fax server 240, the fax terminal 250 transmits a transmission success signal to the message server 230 and receives the content reception signal. One message server 230 transmits a transmission success message to the mobile communication terminal 210 so that the mobile communication terminal 210 can receive the transmission success message, or the fax server 240 transmits the mobile communication terminal through the Internet network. The transmission success signal is transmitted to the 210 so that the mobile communication terminal 210 receives the transmission success message.

If the content is successfully received at the fax terminal 250 and the same content is to be transmitted to the other receiving fax terminal, additional transmission is performed through the input of the additional receiving fax terminal without going through a separate identity authentication and security number assignment step. can do.

The fax server 240 is set in advance so that the application of the mobile communication terminal 210 does not correct the content so that the content is transmitted without being corrected, such as when an ID file is sent when the content is sent to the fax terminal 250 on the receiver side. This may limit the correction at the fax server 240.

The mobile fax service of the present invention is performed by a mobile communication mounted application. The mobile fax service of the present invention will be described as an application according to an embodiment of a step in an application as follows. First, in the authentication and assured number registration and assignment step (S310), when the phone number of the mobile communication terminal 210 is input and receives the authentication number, the received authentication number is input to complete the authentication. When the authentication is completed, you will receive a security number generated from the intelligent network equipment (220).

In the content registration and transmission step (S320), the content to be transmitted through the fax service is registered. The content may be attached as a file, and when the camera is clicked in the application, the picture may be immediately taken by taking a picture with the camera of the mobile communication terminal 210. Clicking "Send ID" in the registration and transmission of the fax content (S320) sets the attached file or photo to be transmitted from the fax server 240 to the receiving side fax terminal 250 without correction. When the content is registered in the application and the recipient number is input in the 'receive fax number', the content is transmitted to the receiving side fax terminal 250 by pressing 'send'. In this case, the same content may be transmitted to another receiving terminal, and the deleted content may be immediately deleted without storing the transmitted content in the fax server 240.

The application can also check whether the content is received by the receiving terminal (250). If the receiving fax terminal 250 fails to receive the fax, the application 'fax transmission failed' notification window appears in the application, the 'retransmission' in the application is the same content without the identity authentication and security number registration and assignment step (S310) It can be retransmitted to the receiving fax terminal 250.

The mobile communication terminal 210 may check the transmission history (S330). The fax server 240 of the present invention receives a signal indicating whether the content is received from the receiving side fax terminal 250 and transmits the content receiving data to the mobile communication terminal 210. When the content reception data for each fax content transmission is transmitted to the mobile communication terminal 210, the application of the mobile communication terminal 210 displays all transmission history, and stored in the fax server 240 through the transmission history. The transmitted content may be deleted, or the content stored in the fax server 240 may be retransmitted to another receiving side fax terminal without going through the authentication and security number registration and assignment step (S310).

In addition, after receiving the content, the fax terminal 250 of the present invention can send a fax service to the security number for the received content. That is, the receiving side fax terminal 250 becomes the calling side fax terminal 260, and the assured number of the mobile communication terminal 210, which was the calling side, becomes the receiving side number for receiving the content.

In this case, when the fax terminal 260 transmits the security number and the content for the fax service to the fax server 240, the fax server 240 corresponds to the mobile communication terminal 210 corresponding to the security number stored in the previous transmission history. By matching the phone number of the content for the fax service is transmitted to the message server 230 of the matched mobile communication terminal 210. The message server 230 receiving the content and the telephone number of the mobile communication terminal 210 transmits the content to the corresponding mobile communication terminal 210 using the MMS through the mobile communication network, and the mobile communication terminal 210. The fax service is completed by receiving the content at.

The content received from the mobile communication terminal 210 can be confirmed by the application of the mobile communication terminal 210 (S340). In addition to confirming the received fax history, the received content may be transmitted to a fax terminal of another destination, or may be transmitted to another mobile communication terminal by MMS, or the received content may be transmitted by e-mail.

The function of the application may be set in order to re-receive the security number or to transmit the content received through the fax service by mail (S350). In addition, if the fax reception alarm setting function is checked, the content reception status is notified through an application when the content is received from the receiving fax.
