The present invention relates to a method for authenticating a mobile communication terminal, and more particularly, to a method for privately authenticating the mobile communication terminal using a secret code included in a specific message provided by a specific network operator.

As the use of mobile communication terminals increases rapidly due to the convenience of portability, service providers (terminal manufacturers) are developing more convenient and special functions to secure more users. For example, the mobile communication terminal may include a phone book, a game, a scheduler, a short message, the internet, an e-mail, a morning call, a morning call, It provides various functions such as MP3 (MPEG Layer3) and digital camera.

As described above, the mobile communication terminal has rapidly increased in use due to the convenience of portability and the development of various additional functions, and has become a necessity of modern life.

As the use of the mobile communication terminal increases, problems caused by the increase of the use of the mobile communication terminal have arisen. One of the problems encountered is a pirated phone.

The counterfeit phone copies a unique serial number (hereinafter referred to as ESN) stored in a ROM of the mobile communication terminal using a device called a ROM writer to form a mobile phone network. It refers to the use of several mobile communication terminals together with a mobile identification number (hereinafter referred to as MIN) given after signing up.

As described above, due to the increase in illegal users using the pirated phones, legitimate mobile phone subscribers are suffering from congestion, confusion, etc. There was a problem that could cause big social problems.

Accordingly, an object of the present invention is to provide a method for preventing illegal duplication of a mobile communication terminal.

Another object of the present invention is to provide a method for preventing illegal copying of a mobile communication terminal using a secret code provided from a network operator.

Still another object of the present invention is to provide a method for restricting access of important information of a mobile communication terminal according to the presence or absence of a secret code provided from a network operator.

According to a first aspect of the present invention for achieving the above objects, a method for privately authenticating a mobile communication terminal, when attempting to register with a specific network operator, receives a registration permission message containing a secret code from the specific network operator; Receiving, checking and storing the secret code included in the registration permission message, when there is a request for access to incoming and outgoing and important information, the step of checking whether the secret code exists, and the secret code exists In the case, characterized in that it comprises the process of allowing access to the incoming and outgoing and important information.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, if 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 describes a technique for performing private authentication for the mobile communication terminal using a secret code included in a specific message provided by a specific network operator. In other words, a technique for restricting access to important information of the mobile communication terminal according to the presence or absence of the secret code in the mobile communication terminal will be described. In general, illegal copying of the terminal changes the important information of the terminal that is not registered in a specific network operator to be registered in the specific network operator. However, if the terminal does not have a secret code provided from a specific network operator as in the present invention, important information cannot be accessed, thereby preventing illegal duplication of the terminal.
In the following description, the message includes a short message service (SMS) message, an e-mail, a multimedia message system (MMS) message, an enhanced message service (EMS) message, and the like. In addition, in the following description, a network operator refers to an individual provider that provides a wireless mobile communication service.

1 is a block diagram of a mobile communication terminal according to the present invention. The mobile communication terminal described below includes a cellular phone, a personal communication system (PCS), a personal data assistant (PDA), and an international mobile communication-2000 (IMT2000) terminal. The following description will be described with the general configuration of the above examples.

Referring to FIG. 1, first, a microprocessor unit (MPU) 100 controls the overall operation of the mobile communication terminal. For example, it performs processing and control for voice call and data communication, and restricts the access of the incoming and outgoing and important information according to the presence or absence of secret code when accessing incoming and outgoing and important information according to the present invention in addition to the usual functions. To handle the function. Therefore, in the following description, description about the process and control of the normal control part 100 is abbreviate | omitted. Here, the secret code refers to a code provided from a network operator to which the mobile communication terminal subscribes to prevent illegal duplication of the mobile communication terminal.

The ROM 102 may store microcodes and various reference data of a program for processing and controlling the controller 100. In particular, according to the present invention stores a program for restricting access to incoming and outgoing and important information according to the presence or absence of the secret code. Random Access Memory (RAM) 104 is a working memory of the controller 100 and stores temporary data generated during execution of various programs. Flash ROM 106 stores various updatable archiving data such as phone books, outgoing messages and incoming messages.

The keypad (key pad) 108 is a numeric key buttons of 0-9, menu button (menu), cancel button (clear), confirmation button, call button (TALK), end button (END), Internet access button, A plurality of function keys such as navigation key (or direction key) buttons (▲ / ▼ / ◀ / ▶) are provided, and key input data corresponding to a key pressed by the user is provided to the controller 100. The display 110 displays status information generated during the operation of the mobile communication terminal, a limited number of characters, a large amount of video and still images, and the like. The display unit 110 may use a color liquid crystal display (LCD).

The codec (Coder-Decoder) 112 connected to the control unit 100 and the speaker 116 and the microphone 114 connected to the codec 112 are voice input / output blocks used for phone calls and voice recording. . The codec 112 converts the PCM data provided from the controller 100 into an analog voice signal, transmits the same through the speaker 116, and converts the voice signal received through the microphone 114 into PCM data. To the control unit 100.

In addition, the RF unit (Radio Frequency unit) (120) is the frequency of the radio frequency signal received via the antenna 118 is provided to the baseband processing unit 122 by lowering the frequency, the baseband signal from the baseband processing unit 122 The frequency is raised and transmitted through the antenna 118. The baseband processor 122 processes a baseband signal transmitted and received between the RF unit 120 and the controller 100. 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 despreading and channel decoding of the received signal is performed. To perform.

2 illustrates a procedure for registering a secret code in a mobile communication terminal according to an embodiment of the present invention.

Referring to FIG. 2, first, the terminal 200 transmits a registration request message to the network operator 202 to subscribe to the network operator 202 (step 203). The network operator 202 receiving the registration request message includes the secret code in the registration permission message of the terminal 200 and transmits the secret code to the terminal 200 (step 205).

Upon receiving the registration permission message, the terminal 200 displays only the registration permission message (for example, "congratulations of xxx's subscription!") On the display 110, and is included in the registration permission message. The secret code is not displayed on the display unit 110 but stored in the terminal 200 (step 207). Here, the secret code is set to a null value before being provided by the network operator.
In this case, the terminal 200 must include a secret code registered and provided to the network operator 202 to access the call and important information. That is, the terminal without the secret code is not registered in the network operator 202 cannot access important information. Therefore, illegal duplication of changing important information of a terminal not registered in the network operator 202 can be prevented.

3 shows a procedure for performing private authentication for a mobile communication terminal according to an embodiment of the present invention. In the following description, a case where a user of a terminal attempts to make a call with another terminal will be described.

Referring to FIG. 3, first, in step 301, the controller 100 checks whether there is a call request. That is, it is checked whether the call button is pressed by the user's key manipulation in order to attempt to connect the call to another terminal. If there is no call request, the control unit 100 proceeds to step 309 to perform a corresponding mode (eg, standby mode).

If the origination request is made, the control unit 100 proceeds to step 303 and checks whether there is a secret code provided from the network operator through the process as shown in FIG. 2. If the secret code does not exist, that is, if the secret code is a null value, the control unit 100 proceeds to step 307 and displays the reject message (eg, "register a terminal!"). The controller 100 ends the present algorithm. Here, the secret code has a null value if the secret code is not provided from the network operator.

If the secret code is present, the controller 100 proceeds to step 305 and transmits an outgoing request message to the base station in order to connect the call with the other terminal. Thereafter, the controller 100 ends the present algorithm.

Since it is not shown, the terminal receives the secret code cancellation message from the network provider that provided the secret code in order to terminate the subscription to the network provider and move to another network provider to register the secret code registered in the terminal After removal, you can move to another network operator.

The above-described example is to limit the call connection according to the presence or absence of a secret code provided from the network operator to the terminal when the originating request of the terminal. In addition to this, in another embodiment, even when there is an incoming request to the terminal, the incoming request is restricted according to the presence or absence of the secret code in the terminal. That is, if the secret code exists, the incoming request is notified to the user, but if the secret code does not exist, the incoming request is rejected.

In another embodiment, when the terminal attempts to enter the NAM editor before registering with the network operator, even if the NAM edit code is correctly input, the secret code provided from the network operator exists in the terminal. If not, the NAM editor will not be allowed to enter. That is, the secret code is used to prevent illegally changing important information of the terminal.

In addition, even when downloading the other binary code (Binary code), the secret code must exist in the terminal so that the other binary code can be downloaded.

However, in the development of the terminal, it is possible to access important information of the terminal by using a specific password (for example, a master key password) assigned to the developers.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, a network operator provides a secret code to a mobile communication terminal that wants to join the network, and authenticates the mobile communication terminal using the secret code, that is, accesses incoming and outgoing and important information from the mobile communication terminal. At the time, when the secret code exists only by allowing the incoming and outgoing and important information access, the user of the mobile communication terminal can make a safe call, and there is an advantage of preventing the use of the illegally copied mobile communication terminal.
