As described above, a method for selectively forwarding a message including personal information when the subscriber uses the call forwarding service will be described with reference to FIGS. 2 through 3.

2 is a first flowchart illustrating a method for forwarding a message according to an embodiment of the present invention.

As shown in FIG. 2, when the subscriber uses the supplementary service, the calling terminal may transmit a message including the subscriber's personal information to the MSC (S210).

In this case, the message may include a calling party number, a called party number, a call forwarding number, message content, a call forwarding indicator, and an additional service indicator.

When the MSC receives the message, it can check the call forwarding status for the called party number to receive the message. For example, the MSC may request and receive a call forwarding status from a home location register (HLR).

In this case, the call forwarding state may mean an activation state indicating that call forwarding is possible for the called party number and an inactive state indicating that call forwarding is impossible.

The MSC may generate a delivery message that includes a call forwarding indicator indicating the call forwarding status. The MSC may transmit the generated delivery message to the server (S220).

The server may check the call forwarding indicator included in the delivery message by receiving the delivery message (S230). That is, if the call forwarding state is activated, the server may generate a query message for requesting whether to forward the message.

Accordingly, the server may transmit the generated search message to the subscriber DB (S240).

This search message can be used to know whether or not to selectively forward the message when the call forwarding state for the called party number is activated.

The subscriber DB may search for a preset service class indicator for an additional service that receives the search message and provides the message based on the search message.

The subscriber DB may generate a result message including the retrieved service class indicator. The subscriber DB may transmit the generated result message to the server (S250).

In this case, the subscriber DB may store and manage the preset service class indicators for each additional service providing a message including personal information.

Thereafter, the server may receive the result message and check the service class indicator included therein (S260). That is, the server may determine that call forwarding is possible based on the service class indicator.

The server may generate a submit message for notifying that call forwarding is possible according to the service class indicator. The server may transmit the generated submission message to the MSC (S270).

As a result, the MSC may receive the submitted message and transmit the message to the call forwarding terminal based on the received message (S280).

The call forwarding terminal may generate a report message for receiving and reporting the message. The called terminal may transmit the generated report message to the MSC (S290).

The server may generate a submission message to indicate that the call forwarding is not possible according to the service class indicator. The server may transmit the generated submission message to the MSC (S370).

As a result, the MSC may receive the submitted message and transmit the message to the called terminal based on the received message (S380).

The called terminal may receive a message and generate a report message for reporting it. The called terminal may transmit the generated report message to the MSC (S390).

In addition, the MSC may receive the report message and forward it to the server (S391).

On the other hand, the present invention is not limited to a method of forwarding an SMS (Short Message Service) message including personal information. That is, the present invention can be equally applied to a method of forwarding a long message service (LMS) message or a multimedia message (MMS) message that may include personal information.

The present invention includes a separate server for selectively informing whether or not to transfer the call according to the service class indicator. This will be described with reference to FIGS. 4 to 5.
