Referring to the MMS service in the conventional mobile communication terminal, first, the mobile communication terminal attaches the calling subscriber number and the called subscriber number to the MMS message to be transmitted to the called terminal after connecting to a predetermined MMS server to transmit the MMS message. When transmitting to the MMS server, the MMS server stores the received MMS message in the internal memory (Disk), and then transmits the MMS message to the corresponding called party's mobile terminal by using the called party's number. Will be provided.

In addition, after the MMS service is normally provided, a charge log (Log) is generated with the calling subscriber number in order to charge the calling subscriber. In the related art, when the calling subscriber is authenticated, it is simply a SKT subscriber using the calling subscriber number included in the MMS message. Alternatively, since only the subscriber number authentication is performed to check whether the subscriber is a third party, there is a problem that it is possible to mass produce and transmit an MMS spam (SPAM) message by transmitting an MMS message by illegally stealing another subscriber's number. In addition, since the MMS server cannot know whether the MMS message is traffic coming from a real subscriber (ie, a normal service subscriber) terminal, there is a problem that it cannot control an MMS hacking message that arbitrarily steals another's subscriber number and arbitrarily sets an originating subscriber number. To the actual subscriber There was a problem in that a lot of damage occurs materially, such as incorrect charging occurs.

In the present invention, when using the MMS service using the mobile terminal simply performs authentication on the calling subscriber number included in the MMS message, by authenticating the model number of the calling subscriber terminal that actually sent the MMS message, the subscriber number of others It is possible to block MMS spam messages or MMS hacking messages in the form of illegal theft, the system configuration for this is as shown in FIG.

That is, in the MMS service authentication system of the mobile communication terminal according to the present invention, as shown in FIG. 1, the mobile communication terminal 10, the MMS server 20, and the UAPS (User Agent Profile System) server 30 interwork with each other. Has a configuration.

The mobile communication terminal 10 is an outgoing subscriber terminal for sending an MMS message, and attaches its subscriber number (calling subscriber number) and the called subscriber number to an MMS message to be transmitted to the called terminal by accessing the MMS server 20. 20, and when using a wireless Internet service for sending an MMS message, UA (User Agent) information including a terminal model number is transmitted to the MMS server 20.

Here, the UA information is identification information required for using the service such as subscriber number, terminal information, and base station information transmitted by the mobile communication terminal 10 when using a wireless Internet service such as NATE. Information, service type information, network classification information, model serial number indicating the terminal type, browser type, terminal version, screen size, maximum number of characters (English), color information, MIN number, base station information, and the like are included.

The MMS server 20 checks the MMS message format transmitted from the mobile communication terminal 10, sends the calling subscriber number included in the MMS message to the UAPS server 30, requests the subscriber number authentication, and at the same time, the terminal model. MMS message by requesting the information and checking the terminal model information (terminal type information) transmitted from the UAPS server 30 and the terminal model number included in the UA information transmitted from the mobile communication terminal 10 when the calling party number authentication is successful. Performs a series of terminal model authentication to confirm whether the service is normally transmitted from the registered subscriber terminal, and when the terminal model authentication succeeds, stores the MMS message in the internal memory (Disk), and then transmits the called party number to the UAPS server 30. Request the subscriber number authentication, and when the called party number authentication succeeds, the corresponding party's mobile communication is made using the called subscriber number. After sending the MMS message to the new terminal, a billing log is generated with the calling party number.

The UAPS server 30 performs a subscriber authentication function to provide a wireless Internet service and stores terminal information. The UAPS server 30 authenticates the calling party number and the called party number according to the subscriber authentication request of the MMS server 20. The MMS server 20 responds to the MMS server 20 and transmits the terminal model information corresponding to the calling party number to the MMS server 20 according to the request for the terminal model information of the MMS server 20.

The MMS service authentication operation of the mobile communication terminal according to the present invention having such a configuration will be described in detail with reference to FIG. 3 as follows.

First, in order to transmit an MMS message from an arbitrary mobile communication terminal 10, the mobile terminal 10 accesses a predetermined MMS server 20 based on a wireless Internet service, and then sends an outgoing subscriber number and a called party number to an MMS message to be sent to a called terminal. When sent to the MMS server 20 (for example, to the upload port of the vmms.nate.com or mms.nate.com URL), the MMS server 20 sends an MMS message transmitted from the mobile terminal 10. When received, the data format of the MMS message is checked to confirm that the format is correct. At this time, the mobile communication terminal 10 transmits the MMS message and at the same time transmits the UA information necessary for using the wireless Internet service to the MMS server 20.

When the MMS server 20 confirms that the MMS message format transmitted from the mobile communication terminal 10 matches the predetermined format, the MMS server 20 transmits the calling party number included in the MMS message to the UAPS server 30 to authenticate the subscriber number. At the same time, the terminal model information for the calling mobile terminal 10 which has transmitted the MMS message is requested.

Accordingly, the UAPS server 30 performs authentication to confirm whether the subscriber is a normal subscriber with respect to the calling party number transmitted from the MMS server 20 according to the subscriber authentication request of the MMS server 20, and the authentication result is MMS. In response to the server 20, the terminal model information requested by the MMS server 20, that is, the terminal model information corresponding to the calling subscriber number is extracted from the terminal information stored in the MMS server 20. Will be sent.

After that, when the MMS server 20 receives a response from the UAPS server 30 that the originating subscriber number authentication is successful, the MMS server 20 transmits the terminal model information, that is, the terminal type information and the MMS message transmitted together with the authentication result response. By checking the terminal model number included in the UA information transmitted from the mobile communication terminal 10, a series of terminal model authentications are performed to confirm whether the MMS message is transmitted from a subscriber station registered with a service. For example, assuming that the model number of AB 'CD123' terminal is 'AB12', the terminal type transmitted from the UAPS server 30 is 'AB-CD123' and is transmitted from the calling mobile terminal 10. The terminal model number included in the UA information is 'AB12', which corresponds to the same mobile communication terminal, so that the MMS message transmitted from the calling mobile terminal 10 is recognized as being transmitted from the subscriber station registered with the service. do.

In addition, when the MMS server 20 performs the terminal model authentication, and it is recognized that the MMS message transmitted from the calling mobile terminal 10 is transmitted from the subscriber station registered with the normal service, this means that the terminal model authentication is successful. Therefore, the MMS message transmitted from the calling mobile terminal 10 is stored in the internal memory.

Subsequently, when the MMS server 20 transmits the called party number included in the MMS message to the UAPS server 30 to request subscriber number authentication, the UAPS server 30 responds to the request for subscriber authentication from the MMS server 20. Authentication is performed to confirm whether the subscriber is a normal subscriber with respect to the called party number transmitted from the MMS server 20, and the authentication result is returned to the MMS server 20.

At this time, when the MMS server 20 receives a response from the UAPS server 30 that the called party authentication is successful, the MMS server 20 transmits an MMS message to the corresponding called party's mobile terminal by using the called party number. By generating the billing log with the subscriber number, the series of MMS services is terminated.

On the other hand, the embodiment according to the present invention is not limited to the above, it can be carried out by various alternatives, modifications and changes within the scope apparent to those skilled in the art with respect to the present invention.

As described above, the present invention performs terminal model authentication as well as subscriber number authentication of the calling mobile terminal when using the MMS service using the mobile terminal, thereby illegally stealing the subscriber's number of another person from the operator's point of view. In addition, it is possible to block abnormal MMS message transmission such as MMS hacking message, thereby preventing charging accidents such as incorrect charging occurs to the terminal user who did not actually send the MMS message.
