The present invention relates to a mobile communication terminal equipped with a SIM card, and more particularly, to an environment setting method according to a SIM card.

In general, a communication method applied to a wireless communication terminal is GSM (Global System for Mobile Communication; GSM), a time division multiple access method in Europe, and TDMA (Time Division Multiple Access), a time division multiplex method in North America. And the Code Division Multiple Access (CDMA) method, which is a code division multiplexing method.

Among the communication schemes, the GSM scheme is an international standard for ensuring compatibility among various network users, and is widely used in various countries including Europe, and includes a subscriber identity module (Subscriber Identity Module); Hereafter referred to as 'SIM' card is mounted. Here, the SIM card is a smart card that can be attached to or detached from a wireless communication terminal. The SIM card includes a microprocessor and a memory chip, and includes an IC card type and a plug-in type. . As described above, the SIM card has a microprocessor and a memory chip mounted therein, and includes almost all information necessary for operating a wireless communication terminal. In particular, the SIM card includes not only personal information of a user, but also a telephone number and a network number. Data containing information is encrypted and embedded. Therefore, a GSM terminal can make a call only after being authenticated by the SIM card and cannot make a phone call except for an emergency call without the SIM card.

The SIM card also checks whether the user is registered in the network, and in order to prevent the use of a user who is not registered in the network, a personal identification number (PIN) and a personal unblocking key (PUK). ) Is being saved. Therefore, the user must enter a four-digit password to use the wireless communication terminal. If the wrong PIN is entered more than three times, the SIM card is blocked, and in order to release it, an eight-digit PUK must be input. Due to this complementary user, his SIM card can be installed simply on his or her wireless communication terminal as well as another person's wireless communication terminal. That is, even if the user moves to the United States or far away, the user can carry only the SIM card and mount it on a wireless communication terminal using the SIM card to make a call.

Meanwhile, the wireless communication terminal equipped with the SIM card may set an environment such as a ring tone, a wallpaper, and a volume value desired by the terminal owner, and may store the set environment and continue to operate at the next power on. The terminal may be used in a desired environment. However, when another user inserts another SIM card into the terminal, in the prior art, since the terminal is powered on as the environment set by the previous person, the new user must reset the desired environment. There is a problem.

An object of the present invention is to provide a method for setting an environment of a mobile communication terminal equipped with a SIM card.

According to an embodiment of the present invention to achieve the above object, when the insertion of the SIM card is detected, the process of generating a key value with the unique number of the SIM card and the current environment value of the terminal, and the generated key value When the same as the most recently used key value, setting the environment of the terminal as it is, and when the generated key value is not the same as the most recently used key value, the unique number equal to the generated key value by searching the memory And checking whether there is another key value configured as a second key, and setting the environment of the terminal as an environment according to the found key value when another key value configured with the unique number is searched.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

Hereinafter, the present invention will be described in an environment setting method of a mobile communication terminal equipped with a SIM card.

1 illustrates a configuration of a mobile communication terminal equipped with a SIM card according to the present invention.

Referring to FIG. 1, a control unit (MPU: Micro-Processor Unit) 101 of the mobile communication terminal 100 controls the overall operation of the mobile communication terminal 100. For example, it performs processing and control for voice communication and data communication, and processes the function for setting the environment according to the SIM card in accordance with the present invention in addition to the usual functions. Therefore, in the following description, description regarding the processing and control of the normal control unit 101 is omitted.

The ROM (Read Only Memory) 103 stores the microcode of the program and various reference data for processing and control of the controller 101. In particular, according to the invention, a program for setting an environment according to the SIM card is stored. A random access memory (RAM) 105 is a working memory of the controller 101 and stores temporary data generated during execution of various programs. The flash RAM 107 stores various updatable data for storage, and in particular, a key generated according to the present invention from the unique information (IMSI) value of the SIM card, the mobile phone environment value, and a combination of the two values. Save the (KEY) value.

The keypad 109 includes numeric keys 0 to 9, a menu button, a cancel button (clear), an OK button, a call button (TALK), an end button (END), an internet access button, and a navigation key (or Direction keys), buttons (▲ / ▼ / ◀ / ▶), and a plurality of function keys, and provide key input data corresponding to a key pressed by the user to the controller 101. The display 111 displays status information generated during the operation of the portable terminal, a limited number of characters, a large amount of video and still images, and the like. The display unit 111 may use a color liquid crystal display (LCD).

The codec 113 connected to the control unit 101, the speaker 117 and the microphone 115 connected to the codec 113 are voice input / output blocks used for telephony communication and voice recording. The codec 113 converts the digital data provided from the control unit 101 into an analog voice signal and transmits it through the speaker 117, and converts the voice signal received through the microphone 115 into digital data. Provided to the controller 101.

In addition, the RF module 121 lowers the frequency of the radio frequency signal received through the antenna 123 to the baseband processor 119 and provides the baseband signal from the baseband processor 119. The frequency is increased and transmitted through the antenna 123. The baseband processor 119 processes a baseband signal transmitted and received between the RF module 121 and the controller 101. For example, in the case of transmission, the channel coding and spreading of data to be transmitted are performed, and in the case of reception, the function of de-spreading and channel decoding of the received signal is performed. To perform.

The SIM card 125 is a smart card detachable to a mobile communication terminal using a Global System for Mobile Communication (GSM) communication method, and registers subscriber information such as a user password and data and network registration for operating the mobile communication terminal. Data is stored. Here, the SIM 125 card stores an International Mobile Subscriber Identity (IMSI), which is a unique number, and the IMSI is used for authentication when accessing the system.

2 is a diagram illustrating a method of generating a key value using an environment combination of a mobile communication terminal according to an exemplary embodiment of the present invention.

Referring to FIG. 2, in step 201, the controller 101 stores IMSI, which is unique information of the SIM card 125, and an environment value according to a user's phone environment setting in the memory 107. Here, the environment value may be defined as a predetermined bit, for example, the environment value '0135' sets the first sound as the ringtone of the terminal, sets the third picture as the wallpaper, and sets the fifth level as the above. It may mean a value set to the size of the ringtone.

In step 203, the controller 101 checks whether there is a key input for setting the environment of the current terminal. If a key input for setting a current environment of the terminal is not detected, the controller 101 proceeds to step 205 to recompose the user's phone environment, that is, to change and store an environment such as a ringtone and a background screen. Check for this. Here, the key for environmental recombination may be, for example, a key for changing the ringtone of the terminal to another ringtone or changing the background screen of the terminal to another picture.

When a key input for changing the mobile phone environment is detected, the controller 101 proceeds to step 207 to generate a new environment value according to the environment change and update a previous environment value with the newly generated environment value. After that, the process returns to step 203 to check whether there is a key input for environment setting. When a key input for changing the mobile phone environment is not detected, the controller 101 performs a corresponding function.

When a key input for setting the current environment of the terminal is detected in step 203, the controller 101 proceeds to step 209 and the environment value of the terminal stored in the memory 107 and the current SIM card ( A key value is generated using a unique number, i.e., an IMSI value of 125, and the generated key value is stored in the memory 107. For example, when the IMSI value is '1234' and the changed environment value is '135', a key value of '12340135' may be stored in the memory. Thereafter, the controller 101 ends the algorithm according to the present invention.

3 is a diagram illustrating an environment setting method according to a SIM card of a mobile communication terminal according to an embodiment of the present invention.

Referring to FIG. 3, the controller 101 checks whether the SIM card 125 is inserted in step 301. When the insertion of the SIM card 125 is detected, the controller 101 proceeds to step 303 and the IMSI (unique number) value of the SIM card 125 and the current environment of the terminal stored in the memory 107. Create a key value using the value. For example, when the IMSI value is '1234' and the current environment value is '135', a key value of '12340135' may be generated.

In step 305, the controller 101 checks whether the generated key value is the same as a key value recently used as a terminal environment. When the generated key value is the same as the latest key value, the controller 101 may set the terminal as it was previously used by setting the latest terminal environment according to the recent key value as it is.

When the generated key value is different from the latest key value, the controller 101 checks whether there is a key value configured as the IMSI value in the memory (307). When the key value composed of the IMSI value is not retrieved, the controller 101 sets the environment of the terminal as the default environment. When the key value composed of the IMSI value is found, the controller 101 proceeds to step 309 and sets the environment of the terminal to an environment according to the found key value.

 For example, when the newly generated key value is '15550135' and the previous key value is '12340135', since the IMSI values of the two key values are different, the environment of the terminal is not set as it is. Therefore, the controller 101 determines whether there is a key value (eg, '15550246') having an IMSI value of the newly generated key value, that is, '1555' among other key values stored in the memory 107. Search and set the environment of the terminal according to the found key value. If there is no key value having the same IMSI value, the controller 101 sets the environment of the terminal as the default environment. Thereafter, the controller 101 ends the algorithm according to the present invention.
