1 is a diagram schematically showing the configuration of an entire system for controlling a called terminal located at a remote location by using a calling terminal according to an embodiment of the present invention.

Referring to FIG. 1, the entire system for controlling a called terminal located at a remote location by using a calling terminal according to an embodiment of the present invention includes a calling terminal 110, a called terminal 120, and a communication network.

According to an embodiment of the present invention, the calling terminal 110 may generate a setup message for controlling the called terminal 120 and transmit it to the called terminal 120 connected through a communication network. 120 may perform an operation of limiting some of the functions of the called terminal 120 according to the received setup message. Here, the setup message includes a control list for limiting the function of the called terminal 120, and the control list is set in the User-User field of the setup message. At this time, the control list set in the User-User field is not processed at the communication network end (for example, the exchange). That is, the user may directly control the terminating terminal 120 located at a remote location by driving the terminating terminal 120 control application set in the originating terminal 110.

The calling terminal 110 and the called terminal 120 may be applied without limitation as long as the terminal can provide a communication function. For example, the calling terminal 110 and the called terminal 120 may be provided with a personal mobile communication terminal (PCS), a personal digital terminal (PDA), a smart phone, a next generation mobile communication terminal (IMT-2000) capable of providing voice communication. , A wireless LAN terminal, or the like.

Hereinafter, the control method of the terminating terminal 120 located at a remote location will be described in detail with reference to FIGS. 2 and 3.

2 is a flowchart illustrating a method of controlling a called terminal located at a remote location performed by a calling terminal according to an embodiment of the present invention, and FIG. 3 is a view illustrating a driving screen of a terminal control application according to an embodiment of the present invention. Drawing.

Referring to FIG. 2, in step 210, a terminal control application for controlling a terminating terminal 120 located at a remote location is driven according to a command of a user of the originating terminal 110. That is, the user may allow the terminal control application to be driven on the originating terminal 110 through a key button input preset in the originating terminal 110 or a menu input implemented in the originating terminal 110.

Referring to FIG. 3, when the terminal control application is driven, the calling terminal 110 displays a screen of reference numeral 310. Of course, the configuration of the reference numeral 310 is only an embodiment for the description of the present invention, it is apparent that the present invention is not limited thereto. As shown at 310, the terminal control menu may include a called number input menu, a control list input menu, and a password input menu. In this case, the called number is a menu for receiving the number of the called terminal 120 whose function is to be restricted. In addition, the password is a menu for receiving information to be used as the authentication identifier in the destination terminal 120. In addition, the control list is a menu for selecting a function for limiting among the functions of the called terminal 120. For example, when the user selects a control list input menu, the calling terminal 110 may output a screen 320. In this case, the user may limit the function of the called terminal 120 by selecting one or more of the control list shown at 320.

As in the example described above in step 220, the calling terminal 110 may receive a control list for controlling the called terminal 120 from the user. Here, the control list may be a phone call access control, a connectionless card control, camera use control, album access control, SMS Viewer access control, outgoing control, incoming call control.

In addition, although not shown in FIG. 2, the calling terminal 110 may further receive an authentication identifier (for example, a combination of numbers or characters having a certain digit) from a user. For example, the calling terminal 110 may receive an authentication identifier in the form of a password from the user (see FIG. 3).

In step 230, the originating terminal generates a setup message including a control list. Here, the setup message may further include an authentication identifier. In addition, the setup message may be a message in the 3GPP standard. More specifically, the generation of the setup message may be setting the control list in the User-User field of the setup message. As described above, when the calling terminal 110 further receives an authentication identifier, the input authentication identifier may also be set in the User-User field. At this time, the User-User field is preferably not processed in the network terminal via the signal between the calling terminal 110 and the called terminal 120. That is, it is preferable that the information set in the User-User field is not processed in the devices constituting the network (for example, the exchange, etc.), and thus, the calling terminal 110 directly controls the called terminal 120. The effect can be generated. The setup message contents in the 3GPP standard are as follows.

In step 240, the calling terminal 110 transmits the generated setup message to the called terminal 120. In this case, the calling terminal 110 may transmit a setup message to the called terminal 120 in response to the call attempt command of the user. That is, the setup message may be transmitted to the called terminal 120 via the communication network through the voice call attempt channel.

Subsequently, although not shown in FIG. 2, the receiving terminal 120 receiving the setup message may perform a function control operation according to the control list. In this case, when the originating terminal 110 further receives an authentication identifier from the user, the setup message further includes an authentication identifier, and the called terminal 120 matches the authentication identifier preset in the called terminal 120. Function control operation according to the control list can be performed. This will be described in detail with reference to FIG. 4.

4 is a flowchart illustrating a function control method performed in a called terminal according to an embodiment of the present invention.

Referring to FIG. 4, in step 410, the called terminal 120 receives a setup message including a control list from the calling terminal 110. As described above, the setup message may be a message according to the 3GPP standard. Here, the setup message may further include an authentication identifier. As described above, the control list and the authentication identifier may be set in the User-User field of the setup message.

In operation 420, the called terminal 120 may determine whether the User-User field of the setup message is set. That is, the called terminal 120 may determine whether any information is included in the User-User field of the setup message. As a result of determination, when the User-User field is set, the called terminal 120 proceeds to step 430. If the User-User field is not set, the called terminal 120 does not perform an operation related to controlling the function of the called terminal 120.

In operation 430, the called terminal 120 may perform an authentication process for controlling the terminal. That is, for example, the called terminal 120 may determine whether the authentication identifier included in the setup message and the authentication identifier preset in the called terminal 120 match. As a result of the determination, when the authentication identifiers match, the called terminal 120 performs step 440.

In operation 440, the called terminal 120 may extract the control list included in the setup message to limit the function of the called terminal 120 included in the control list. For example, when the control list includes outgoing control, the called terminal 120 limits the calling function of the called terminal 120.

In step 450, the destination terminal 120 may record the extracted control list in the element-file (EF) of the USIM or SIM. In addition, the called terminal 120 may store the extracted control list in a non-volatile memory. In this case, the recorded or stored control list may be used as information for controlling the called terminal 120 when the third party tries to use the called terminal 120. For example, the terminating terminal 120 receives the recorded or stored control list (for example, phonebook access control information, etc.) when the terminating terminal 120 is set up (for example, power-on of the terminal). After loading in the memory, some of the functions of the called terminal 120 may be restricted according to the control list.

In addition, the control list recorded in the element-file (EF) of the USIM or SIM may be used to control another terminal. For example, if a USIM or SIM on which a control list is recorded is mounted on a third terminal, the third terminal may perform a USIM initialization process (that is, when the third terminal is powered on, the third terminal is connected to the USIM). The process of reading data) may limit some of the functions of the third terminal according to the control list.

Hereinafter, a method of releasing a function control of a terminal in which some functions are limited will be described.

5 is a flowchart illustrating a method of releasing a function control of a called terminal with some limited functions according to an embodiment of the present invention.

Referring to FIG. 5, in step 510, the called terminal 120 receives a setup message including a function release identifier from the calling terminal 110. Here, the setup message may be a message according to the 3GPP standard. In addition, the deactivation identifier may be set in the User-User field of the setup message.

In operation 520, the called terminal 120 may determine whether the User-User field of the setup message is set. That is, the called terminal 120 may determine whether any information is included in the User-User field of the setup message. As a result of determination, when the User-User field is set, the called terminal 120 proceeds to step 530. If the User-User field is not set, the called terminal 120 does not perform an operation related to controlling the function of the called terminal 120.

In operation 530, the called terminal 120 may perform a process for releasing the restricted function. That is, for example, the called terminal 120 may determine whether or not the function release identifier included in the setup message and the preset function release identifier set in the called terminal 120 match. As a result, when the deactivation identifiers match, the called terminal 120 performs step 540.

After activating the restricted function in step 540, the called terminal 120 may proceed to step 550 to delete the control list stored in the nonvolatile memory. In addition, the called terminal 120 may delete the control list recorded in the record in the element-file (EF) of the USIM or SIM.

According to a method for releasing a function control according to another embodiment of the present invention, the called terminal 120 may receive a function release identifier directly from a user other than the calling terminal 110, and subsequent steps 530 to 550 are performed. Can be applied.

The terminal control method according to the present invention described above may be embodied as computer readable codes on a computer readable recording medium. Computer-readable recording media include all types of recording devices that store data that can be read by a computer system. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and also include those implemented in the form of carrier waves such as transmission over the Internet. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion.

Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art to which the present invention pertains without departing from the spirit and scope of the present invention as set forth in the claims below It will be appreciated that modifications and variations can be made.
