The present invention relates to a mobile communication terminal equipped with a user authentication module, and more particularly, to a mobile communication terminal having a user restriction function that is less likely to leak personal information even if another user uses the corresponding user authentication module or mobile communication terminal. It's about how.

Recently, with the development of mobile communication technology, cheaper and various functions of mobile communication terminals have been widely used.

In such a mobile communication terminal, a predetermined user authentication module is applied to enable a user to use mobile communication more conveniently.

The user authentication module used in the present invention is a kind of smart card that can be attached and detached, and the typical use of such a smart card can be used as various payment means such as electronic money (eg, transportation card) or credit card, and moving. It is used as a subscriber identification module for providing a roaming service of a communication terminal.

Such a user authentication module is, for example, a subscriber identity module (SIM) card widely used in the European Global System for Mobile Communication (GSM), a universal subscriber identity module (USIM), which is an advanced form of the SIM card. , The UIM (User Identity Module) card and the 3rd generation code division multiple access system (GSM), which can be adapted to apply the SIM of the European mobile communication technology (GSM) to the 2nd generation code division multiple access (CDMA) There is a Removable User Identity Module (RUIM) card for application to CDMA, and the smart card as the subscriber identification module basically uses a contact smart card for sharing information with the mobile communication terminal.

The user authentication module stores predetermined user information. For example, information such as International Mobile Subscriber Identity (IMSI) is stored. Here, the user information includes information such as a unique serial number for identifying the mobile communication terminal itself, subscription information of a user using the mobile communication terminal, and a user's telephone directory.

Accordingly, the user can carry the predetermined user authentication module and mount the user authentication module on another mobile communication terminal to use the mobile communication terminal as his mobile communication terminal.

For example, when a Korean user travels to Japan, the user separates his user authentication module from his mobile terminal and attaches his user authentication module to a mobile terminal available in Japan. The mobile communication terminal can be used like its own mobile communication terminal.

However, there is a problem with user authentication because one user can use another user's user authentication module in a predetermined mobile communication terminal. For example, even if one user robs another user's user authentication module by illegal means and mounts another user's authentication module to the predetermined mobile communication terminal, the mobile communication terminal authenticates the user with only the user authentication module installed. Can be used. Therefore, a security problem occurs.

Therefore, an object of the present invention is a user restriction function having a low risk of personal information leakage even if a user of the mobile communication terminal loses the user authentication module or the mobile communication terminal. The present invention provides a mobile communication terminal and a method thereof.

Accordingly, the user authentication module is composed of a Removable User Identity Module (RUIM) or Subscriber Identity Module (SIM).

In addition, the user information is composed of an International Mobile Subscriber Identity (IMSI) or an International Mobile Equipment Identity (IMEI).

According to the present invention, there is provided a user authentication method of a mobile communication terminal equipped with a user authentication module storing user information, comprising: a lock function menu selection step of searching / selecting a lock function menu by a user; A user information comparing step of comparing the user information stored in the user authentication module mounted in the mobile communication terminal with the user information of the mobile communication terminal; And an emergency call mode step of operating only an emergency call mode when the user information stored in the user authentication module installed in the mobile communication terminal does not match the user information of the mobile communication terminal. Provide a method.

Here, after the emergency call mode step, if the comparison result by the user information comparison step, it is configured to further include a non-use step to disable the use of the mobile communication terminal if the predetermined number of times do not match.

In the mobile communication terminal according to the present invention, the user information stored in the user authentication module and the user information stored in the storage unit of the mobile communication terminal are identical to each other.

However, the user information of each of the user authentication module and the mobile communication terminal may be different when the user loses either the user authentication module or the mobile communication terminal. In such a case, when another user learns and uses a lost user authentication module or a mobile communication terminal, personal information of the user may be leaked.

Hereinafter, a mobile communication terminal having a user restriction function and a method thereof will be described in detail with reference to the accompanying drawings. However, these drawings are for illustrative purposes only and the present invention is not limited thereto.
