A usage restriction request process (S100), a function usage restriction request approval process (S200) for receiving a function usage restriction request from a terminal user according to a function usage restriction request, and a mobile communication terminal (2) which has received a function usage restriction request from a terminal user ( In step 10), the process of limiting the use of some functions of the mobile communication terminal (S300), and when the mobile communication terminal 10 leaves the measurement place, the function use restriction release process (S400) of releasing the function use restriction It is made to include.

The above-described function use restriction request process S100 will be described with reference to FIG. 3.

First, a terminal user having a mobile communication terminal 10 having a digital camera embedded in a place where privacy is essential, such as a public bath, a toilet, a swimming pool, or a place where corporate secret security is required, such as a corporate research institute or a factory. When coming, the administrator in charge of the place checks the number of the mobile communication terminal from the terminal user who enters the place to register in the function use restriction request server 60.

As described above, when the number of the mobile communication terminal entering the specific place where the function usage restriction request server 60 is installed from the administrator is registered (S102), the function usage restriction request server 60 receives the corresponding mobile communication terminal ( In order to limit the use of the camera and camcorder functions provided in (10), use of a function requesting restrictions on the use of mobile communication terminal numbers registered by the administrator and the use of some functions such as cameras and camcorders provided in the mobile communication terminals. The restriction request message is transmitted to the SMS server 40 (S104).

The SMS server 40 which has received the mobile communication terminal number and the function use restriction request message from the function use restriction request server 60 through the process S104 may transmit the received mobile communication terminal number and the function use restriction request message to the SMC ( 50) (S106), the SMC 50, which has received the mobile terminal number and the function usage restriction request message from the SMS server 40, generates an SMS message using the received function usage restriction message (S108). Based on the received mobile communication terminal number, the position information of the mobile communication terminal is obtained from the HLR 30 (S110).

The base station 20 that has received the SMS message and the mobile communication terminal number through the process S112 transmits the received SMS message and the mobile communication terminal number to a data burst message of the paging channel to the corresponding mobile communication terminal 10 ( S114).

As described above, the mobile communication terminal 10 that has received a function usage restriction request from the function usage restriction request server 60 through the function usage restriction request process S100, as shown in FIG. In step S200, the function usage restriction request approval process for receiving the function usage restriction request from the terminal user is performed.

First, the mobile communication terminal 10 receiving the SMS message through the process S114 analyzes the received SMS message (S202) and determines whether user approval is required (S204).

When the user's approval is required as a result of the determination of step S204, the terminal user is asked whether or not to accept the use restriction for a specific function such as a camera and a camcorder function based on the received SMS message content (S206). It is determined whether the terminal user accepts the restriction on the use of the function (S208), and if the terminal user does not accept the restriction on the use of the function, an alarm sounds until the mobile terminal leaves the place or requests the restriction on the use of the function to the corresponding mobile terminal. Resend the message (S210).

Accordingly, the terminal should approve the function use restriction request when the user enters a place to limit the use of the function.

On the other hand, if the terminal user accepts the restriction on the use of the function as a result of the determination in step S208, the function is stored in the nonvolatile memory to limit the use of some functions of the mobile communication terminal such as a camera and a camcorder based on the contents of the SMS message The usage restriction table is updated (S212).

As a result of the determination of step S208, when the terminal user accepts the restriction on the use of the function, the mobile communication terminal 10 transmits an acceptance message to the function use limit request server 60 through the mobile communication system, so that the terminal user uses the function. The function usage restriction request server 60 knows whether the restriction has been accepted. Accordingly, when the function usage restriction request server 60 does not receive the acceptance message from the mobile communication terminal 10 within a preset time, it is determined that the terminal user does not accept the function usage restriction request, and the function usage restriction request message Will be resent.

Table 1 is a function usage restriction table applied to the method of limiting the use of a function of a mobile terminal according to the present invention. The function use restriction table includes one-to-one matching of a use restriction state and a use limiter for each function provided by the mobile terminal. Stored. Here, the function use restriction may be set by the terminal system and may be set by the terminal user, but the terminal user cannot change the function use restriction state set by the system.

Camera) Usage restriction system Function 4 (ex. Phone number search) Allow use · Function 5 (ex. Send a message) Allow use · Function 6 (ex. Camcorder) Usage restriction user Function 7 Allow use · Function 8 Allow use · : : :

As described above, after receiving the request for limiting the use of a function from the terminal user, if there is a request for performing a predetermined function from the terminal user, as shown in FIG. 5, the process of limiting the use of some functions of the mobile communication terminal ( In step S300, first, when a terminal user is requested to perform a function included in the mobile communication terminal 10 (S302), the function usage limit table is searched to determine whether the function requested to be performed is in a restricted state. It is determined (S304).

If the function requested to perform the determination result of step S304 is in the restricted use state, the terminal user is notified that the function cannot be performed because it is in the restricted use state, and the operation of the corresponding function is not performed (S306).

On the other hand, if the function that is requested to perform the determination result of step S304 is in the allowed state of use, by performing the operation of the corresponding function so that the terminal user can be provided with the desired function (S308).

As described above, when the mobile communication terminal leaves a specific place while allowing / restricting an operation for a function requested by the terminal user according to the usage restriction state, as shown in FIG. S400) is performed.

First, when a terminal user having a mobile communication terminal 10 with a digital camera is removed from a place where privacy is essential or a place where corporate secret security is required, the administrator in charge of the place may request a function usage restriction request server ( 60) request that the terminal user deregister the mobile communication terminal number of the terminal user outside the place.

As described above, when a registration release request for a mobile communication terminal number out of a specific place is requested by the administrator (S402), the function use restriction request server 60 restricts use of camera and camcorder functions provided in the mobile communication terminal. In order to release the message, the mobile communication terminal number requested to release registration from the administrator and a function use restriction release message for releasing the function use restriction are transmitted to the SMS server 40 (S404).

The function use restriction release message transmitted to the SMS server 40 through the process S404 is transferred to the mobile communication terminal 10 through the same process as the function use restriction message (S406), and receives the function use restriction release message. The mobile communication terminal 10 releases the usage restriction on a specific function based on the content usage restriction release message content (S408).

In addition, as another method of releasing the restriction on the use of the function, the mobile communication terminal checks the pseudo number (PN) of the base station receiving the service, and automatically exits the serviced base station at the time when the mobile communication terminal is requested to restrict the use of the function. There is a way to lift the feature usage restriction.

7 is a road, a mobile communication terminal 10, a base station 20, a BSC / MSC 25, showing a configuration of a mobile communication system in which a method of limiting function use of a mobile communication terminal is implemented according to another embodiment of the present invention.
