In the above, the block configuration diagram of the mobile terminal 100 to which the present invention can be applied has been described as an example, and thus the overall description has been made. In the mobile terminal 100 according to an embodiment of the present invention with reference to FIGS. 3 to 7 below. Let's explain how to provide two number service.

3 to 7 are views schematically illustrating a method of providing two-number service.

First, Fig. 3 shows a two-number service performed during a telephone call. Referring to FIG. 3, when the intelligent network system 230 receives an incoming request from a counterpart terminal using an additional phone number to the mobile terminal 100 provided with the two-number service, it is mapped to the additional phone number using the mapping table. Call processing is performed by the mobile terminal 100 by confirming the original telephone number. At this time, the intelligent network system 230 transmits a message including an identifier indicating that an incoming call is requested to an additional phone number to the mobile terminal 100 when processing a call to the mobile terminal 100. For example, the intelligent network system 230 may insert a two number in a type field of a called party subaddress in a setup message. Subsequently, the mobile terminal 100 recognizes that an incoming call is requested in a secure mode by checking an identifier indicating that an incoming call is requested with an additional phone number. Subsequently, the mobile terminal 100 drives the call application, checks the current mode, and performs the incoming call of the voice call requested in the secure mode according to the current mode. For example, when the current mode is the normal mode, the mobile terminal 100 may output a text notifying that an incoming call is requested in the secure mode and a password input field for entering the secure mode. Of course, when the current mode is the secure mode, the mobile terminal 100 can immediately perform the incoming call of the requested voice call in the secure mode. At this time, the mobile terminal 100 may store communication records for telephone calls for each mode. That is, the mobile terminal 100 may allocate a specific area of the memory unit 160 as a dedicated storage for the secure mode, and store communication records generated in the secure mode in the dedicated storage. Here, access to the communication records stored in the dedicated storage may be performed after entering the security mode through authentication, such as entering a password. In addition, the mobile terminal 100 may store the communication record generated in the normal mode in the general storage of the memory unit 160.

Next, FIG. 4 shows a two-number service performed when a message is received. Referring to FIG. 4, when the intelligent network system 230 receives a message incoming request from a counterpart terminal using an additional phone number to the mobile terminal 100 receiving a two-number service, it maps to an additional phone number using a mapping table. The original phone number is checked and the message is transmitted to the mobile terminal 100. At this time, the intelligent network system 230 includes an identifier indicating that the message is transmitted to the additional phone number in the message. Subsequently, the mobile terminal 100 drives the message application according to the reception of the message transmitted to the additional phone number, checks the current mode, and outputs the message transmitted in the secure mode according to the current mode. For example, when the current mode is the normal mode, the mobile terminal 100 may display a message indicating that the message is transmitted in the secure mode and a password input field for entering the secure mode without displaying the message content. Of course, when the current mode is the secure mode, the mobile terminal 100 can directly output the message transmitted in the secure mode. At this time, the mobile terminal 100 may store communication records for the received messages for each mode. That is, the mobile terminal 100 may allocate a specific area of the memory unit 160 as a dedicated storage for the secure mode, and store communication records generated in the secure mode in the dedicated storage. Here, access to the communication records stored in the dedicated storage may be performed after entering the security mode through authentication, such as entering a password. In addition, the mobile terminal 100 may store the communication record generated in the normal mode in the general storage of the memory unit 160.

For example, when a message transmitted to the original phone number is received, the mobile terminal 100 drives the message application according to the message received to the original phone number, and checks the current mode to the normal mode according to the current mode. Outputs the transmitted message. That is, when the current mode is the secure mode, the mobile terminal 100 recognizes that the message is received in a different mode from the current mode, and outputs a message indicating that the message in the normal mode is received. Then, when the user checks the message in the normal mode in the secure mode, the mobile terminal 100 automatically switches the current mode to the normal mode to output the corresponding message, and receives the confirmation input for completing the viewing of the message, automatically You can switch to the previous mode, the security mode.

Here, when the message application is operated in the normal mode, after performing user authentication based on the original telephone number, a friend list in the normal mode may be generated and operated using the address book database in the normal mode. In addition, when the message application is operated in the secure mode, a separate instance is created to separate the data storage space in the secure mode from the normal mode data storage space, and user authentication is performed based on additional phone numbers. You can create and operate a friend list in secure mode using the address book database.

Next, FIG. 5 shows a two-number service performed during data communication. Referring to FIG. 5, the mobile terminal 100 requests data transmission in a secure mode. At this time, the mobile terminal 100 recognizes the state in the secure mode and requests data transmission with an additional phone number. For example, the mobile terminal 100 may transmit a message including an identifier indicating that the call originates to an additional telephone number to the intelligent network system 230. Subsequently, the intelligent network system 230 recognizes that the mobile terminal 100 is calling with an additional phone number, and routes the Internet connection of the mobile terminal 100 to the APN (Access Point Name) server for the security mode to thereby transmit the mobile terminal 100. ) Can be controlled to perform data communication through the APN server for the secure mode. At this time, the intelligent network system 230 may separately generate charging data for the data call through the APN server for the security mode. Through this, it is possible to separate charging for each normal mode and security mode. Similarly, when the mobile terminal 100 sends a voice call or message to an additional phone number, the intelligent network system 230 charges data for the voice call or message through, for example, an exchange for security mode or a message server for security mode. It can also be created separately. Through this, when the user of the mobile terminal 100 wants to use the normal mode for personal use and the security mode for business use, the personal use charges the communication charge by the individual, and the company bears the communication charge for use for the business use. Can be done.

Next, FIG. 6 shows a two-number service for a general application in the mobile terminal 100. Referring to FIG. 6, the mobile terminal 100 receives a notification message of the general application for the security mode in the normal mode. For example, when installing the general application for the security mode, the user may be registered by the user with an additional phone number in the corresponding application service server. Thus, when the application service server transmits a notification message such as an update notification or an event notification to the mobile terminal 100, the mobile terminal 100 may recognize that the application is a general application for a security mode.

Subsequently, in the normal mode, the mobile terminal 100 does not display the content of the notification message according to the occurrence of the notification message of the general application for the security mode, and outputs a phrase indicating that the notification message of the general application for the security mode is received. . For example, as illustrated in FIG. 6, the mobile terminal 100 may output a phrase informing that a notification message of a general application for security mode is received on the upper bar of the screen. Subsequently, when the mobile terminal 100 receives a selection input of a corresponding phrase from the user, the mobile terminal 100 displays a password input screen to receive a password, and when the password authentication is successful, drives a general application for security mode and outputs the content of the notification message. . At this time, the mobile terminal 100 leaves the security mode screen through a button input or the like that moves to the previous screen, and after a certain period of time has elapsed, and receives a selection input of a general application for the security mode again, displays the password input screen and restarts. Authentication can be performed.

Next, Figure 7 shows a two-number service according to the mode of the mobile terminal. Referring to FIG. 7, the mobile terminal 100 receives a driving command of a general application for a security mode in a security mode. For example, the mobile terminal 100 may display an icon indicating that the current mode is a security mode on the upper bar of the screen.

Subsequently, the mobile terminal 100 recognizes that the current mode is a security mode, and drives a general application for the security mode in a separate execution environment from the normal mode. For example, the mobile terminal 100 may execute an additional phone number-based virtual OS environment to drive a general application for the security mode. At this time, the mobile terminal 100 stores various data generated according to the driving of the general application for the security mode in the dedicated storage of the memory unit 160. Meanwhile, when driving the application for the general mode, the mobile terminal 100 stores various data generated according to the operation of the general mode general application in the general storage of the memory unit 160. Of course, when the general application for the general mode is operated in the secure mode, according to the setting, the mobile terminal 100 stores various data generated according to the operation of the general mode general mode application in a dedicated storage of the memory unit 160. It might be.

Meanwhile, the two-number service providing method according to an embodiment of the present invention may be implemented in a form of a program command that can be executed through means for processing various electronic information and recorded in a storage medium.
