Method, System and Apparatus for Restricting Function of Mobile Communication Terminal in Specific zone}

The present invention relates to a method, system and apparatus for limiting the function of a mobile communication terminal in a particular zone. More specifically, when the mobile communication terminal enters a specific zone and performs location registration, when it is determined that the exchange enters a specific zone of the mobile communication terminal using the updated location registration information, the function of the mobile communication terminal The present invention relates to a method, a system, and an apparatus for limiting the function of a mobile communication terminal in a specific zone for controlling to limit the control function and for releasing the restriction function of the mobile communication terminal when the mobile terminal leaves the specific zone.

Recently, as computers, electronics, and communication technologies have advanced dramatically, various wireless communication services using wireless networks have been provided. Accordingly, a service provided by a mobile communication system using a wireless communication network is developing into a multimedia communication service for transmitting data such as circuit data, packet data, and the like, as well as a voice service.

Mobile communication terminals are becoming a necessity of life due to the simplicity and convenience of portable and used by many people.

Previously, it has been used only for voice calls, but recently, many products with camera functions have been released, and the performance of the built-in camera is greatly improved compared to the initial model. In addition, PDAs and MP3 players, such as cameras are being released.

Such a mobile communication terminal has a built-in camera to take a picture, a video, and even a video call, and a user can transfer multimedia data obtained by taking a picture and a video to a counterpart to share with each other.

The user may shoot at a desired place using a camera built-in terminal, and may use the same to prevent people around him from recognizing whether or not the shooting is being performed.

In other words, if the user exploits such a function, the shooting target may not know whether or not to shoot, and thus personal privacy may be violated.

As such, as high-performance camera functions are embedded in mobile communication terminals such as mobile phones, PDAs, and MP3 players, various companies such as research institutes or factories that require various security conditions are increasing the damage of information leakage caused by visitors' mobile phones. .

On the other hand, in order to use the wireless communication through the mobile communication terminal must be connected to the mobile communication network. In a mobile communication network, an area within a predetermined radius of a cell is defined as a cell, and terminals located in a specific cell must perform location registration through a base station of the cell. This is possible.

For example, when the mobile terminal moves from cell A to cell B, there is a hand-off function to prevent the call channel from being disconnected. Location registration for a new location must be performed through the cell's base station.

 The location registration process is briefly described as follows. First, when the location of a specific mobile communication terminal is changed, that is, moving from cell A to cell B, the terminal transmits a location registration request message to the base station of cell B. The location registration request message is transmitted to the home location register via the visitor location register / exchange office, and the home location register updates the location of the terminal and causes the visitor location register to release registration of the previous location of the terminal. Through such a series of location registration process, each terminal can receive registration and authentication for its own location. The above-described location registration process must be performed by each terminal individually.

The mobile communication network provides a service to the mobile communication terminal while guaranteeing mobility. In this case, the mobile communication terminal always registers the location of the terminal at the system side by turning on the power, performing handoff, or periodically performing location registration. I know it.

That is, in the mobile communication network, the periodic location registration of the mobile communication terminal receives a preset location registration period in units of sub-cells of the base station and performs location registration at a period (for example, 90 minutes). The timer performs periodic location registration by driving a set time-based registration timer according to a preset location registration period and performing a location registration procedure when the timer expires.

Therefore, there is a need for a technology development that enables a mobile communication system to check whether a mobile communication terminal enters a specific zone and transmit a camera restriction signal or a camera restriction release signal according to a result of the mobile terminal requesting location registration. It is a situation.
