The present invention relates to a mobile communication terminal system having a voice authentication data generation function and a control method thereof. In particular, the voice of a terminal user is recorded and modulated and encrypted according to a specific frequency to generate authentication data. The present invention relates to a mobile communication terminal system having a voice authentication data generation function and a control method thereof.

In general, a mobile communication terminal system such as a cellular phone or a PDA carries one small portable terminal (about 100 to 150g) for each person and uses various types of digital wireless communication using radio waves in the 2 GHz band. Refers to a service system. However, this definition of personal mobile communication refers to a concept that is independent of the technology or system used. By utilizing various technologies and network systems through liberalization and competition, the general public has a low price that does not differ from landline phones. In particular, the ultimate goal of personal mobile communication is to enable mobile communication in the city center or suburbs, and to communicate with a person's unique number rather than a number associated with a place or vehicle such as a house or office. Therefore, various technologies and systems for realizing such personal mobile communication have been researched and developed in Europe and other countries, among which, in 1988, the UK used a telepoint using a second generation codeless telephone (CT-2) technology. In 1989, the company announced the concept of 'Phones on the Move' and released the Personal Mobile Network (PCN) specification to achieve this. It is a PCS system based on the Global Mobile Communications System (GSM), the European standard for cellular technology, and the Digital European Codeless Telephone System (DECT), the European standard for Digital CT-2. In addition, by using a broadband frequency of 2.7 MHz in the 1.8 GHz band, we built a network of micro-microcells capable of accommodating 100,000 subscribers per km ² in a densely populated urban area. You can also use your PDA to receive voice communications and some additional services. Furthermore, in order to expand the concept of personal mobile communication as described above on a global scale and to provide service anywhere in the world by using a personal number independent of the network, ITU-T is promoting worldwide standardization of personal communication ( UPT).

Then, referring to the conventional mobile communication system as described above with reference to Fig. 1, the mobile communication terminal (70, 71) and the terminal 70 and 71 for transmitting and receiving a CDMA type start and receive signal or perform an Internet connection while moving. The base station system unit 72 processes the call signal transmitted from the mobile station or transmits an incoming call requested from an external system to the terminals 70 and 71 and processes channel information with the terminals 70 and 71 in the sector through a paging channel. ).

Meanwhile, referring to the operation of the conventional mobile communication system as described above, first, when power is applied to the terminal 70, the terminal 70 proceeds to an initialization state to form necessary information in the internal memory and read each parameter. In addition, the terminal 70 executes an initialization process and then receives information necessary for the system including time information through a pilot channel and a sync channel transmitted from the base station system unit 72 and proceeds to the standby state. At this time, the terminal 70 maintains a state capable of receiving a system parameter or a proper response to various messages such as a call through the sink channel in the standby state.

Here, when the user of the terminal 70 wants to access the Internet, first, an Internet access menu is called out on the LCD panel 74 through the keypad 73 and attempts to access the corresponding site. Then, the base station system unit 72 that receives the Internet access signal of the terminal 70 connects to the server 75 of the Internet site, receives the necessary information, and transmits it to the terminal 70. Then, the signal received from the Internet server 75 is displayed on the LCD panel 74 of the terminal 70.

However, such a conventional mobile communication terminal is generally provided for additional service functions such as access to the Internet or execution of other video files, but generates a specific function desired by a user, for example, voice authentication data and generates the authentication data. Since there is no function for connecting to an external system, the user of the terminal cannot use the terminal at all in a manner corresponding to his or her preference, and thus there is a problem in that the use of the terminal is inconvenient.

Accordingly, the present invention has been invented to solve the above problems, and provides a variety of authentication data that can be applied to the authentication system through the terminal, thereby providing a voice authentication data generation function that significantly improves the functionality of the terminal. The purpose is to provide a mobile communication terminal system and a control method thereof.

 Another feature of the present invention is the voice-in data generation step of generating and storing the authentication data by recording and recording the voice of the user of the mobile communication terminal to a specific frequency, and transmits the authentication data to the security equipment system after the voice-in data generation step If the mobile communication terminal wirelessly transmits the authentication data to the security equipment system, the authentication data transmission step requires authentication, and if the security equipment system performs authentication after the authentication data transmission step, the authentication data received from the terminal by the security equipment system is Provided is a control method of a mobile communication terminal system having a voice authentication data generation function comprising an authentication procedure execution step of releasing a security device and transmitting a response signal to a terminal when authentication is performed.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention is a mobile communication terminal (1) for recording the user's voice as shown in Figure 2 and modulated into a specific frequency band (frequency bands invisible to humans) to use as authentication data and to process radio calls, and When the voice authentication data transmitted from the mobile communication terminal 1 or the authentication signal storage terminal 1 are matched with the voice authentication data stored therein, security devices such as a car opening / closing system, an Internet authentication system, or a door opening / closing system It consists of a security equipment system (2) to release the flow.

Here, the mobile communication terminal 1 is a voice recording unit 3 for recording the user's voice, and the voice recorded by the voice recording unit 3 to a specific frequency band (frequency band that can not be heard by people) A key word for controlling the modulation and authentication function of the voice modulation unit 4 for modulating and converting the authentication data into authentication data and the authentication data generated by the voice modulation unit 4 and for controlling the overall functions of the mobile communication terminal 1. A memory unit 6 for storing the authentication data generated according to the storage control signal of the main controller 5 and a variety of information of the mobile communication terminal 1, and the terminal 1 Installed in some body of the display 7 to display the various information signals therein, including the authentication procedure screen to the outside, and wirelessly connected to the security equipment system through the authentication data in accordance with the control signal of the main controller 5 Run the authentication process and An analog voice signal input through the handset 9 according to a call connection control signal of the radio module unit 8 and the main control unit 5 that process a radio call signal transmitted and received in the same communication terminal 1. A key panel for converting a digital signal or a digital voice signal into an analog signal, outputting the coded signal 10 to reproduce the authentication data, and inputting a user's function setting signal to the main control unit 5; And a part 11.

In addition, the authentication data of the voice modulator 4 may be configured in a constant frequency form or a digital signal form.

The security equipment system 2 extracts and outputs only the authentication data by demodulating the data transmitted from the terminal 1 and the authentication data storage unit 12 storing the authentication data generated by the terminal 1. An authentication data extracting unit 13 and an authentication processing unit 14 for determining whether to authenticate by comparing the authentication data extracted by the authentication data extracting unit 13 with the authentication data stored in the authentication data storage unit, and the authentication processing unit. When the authentication is determined by (14), it includes an actuator 15 for releasing the inflow and outflow of a security device, such as a car opening and closing system, an Internet authentication system, or a door opening and closing system.

Then, after the voice in data generation step (S2) proceeds to the authentication request confirmation step (S3) to check whether the signal for authentication to the security equipment system is set using the authentication data of the current mobile communication terminal. At this time, when the authentication request confirmation step (S3) is confirmed as a result of the authentication request signal to the security equipment system using the authentication data of the current mobile communication terminal is not set to the general call processing step (S4) proceeds to the general call processing function Run

That is, when power is applied to the terminal 1 of the present invention, the main controller 5 of the terminal 1 proceeds to an initialization state, forms necessary information from the internal memory unit 6, executes an initialization process, and then waits. Proceed to state.

At this time, the main control unit 5 of the terminal 1 recognizes when the user inputs a telephone number through the key panel unit 11 and presses a call button, and the user inputs the telephone number into the memory unit 6. In addition to the storage, the system accesses the base station system unit 16 using the access channel through the wireless module unit 8, and then transmits an outgoing signal to the corresponding telephone number.

Then, the voice recording unit 3 modulates the voice recorded by the voice modulator 4 into a specific frequency band (a frequency band invisible to human being) in accordance with the function control signal of the main controller 5. Is converted into the memory unit 6 and then stored in the memory unit 6.

In this case, the authentication data stored in the terminal 1 is also stored in the authentication data storage unit 12 of the security equipment system 2 to be secured.

On the other hand, when the terminal user performs the flow of the security equipment system (2), for example, vehicle opening and closing system, Internet authentication system or door opening and closing system using the terminal after the above process, the main control unit 5 of the terminal 1 The authentication data stored in the memory unit 6 is called out and wirelessly transmitted to the security equipment system 2 through the wireless module unit 8.

At this time, the authentication data transmitted from the terminal 1 is transmitted in the form of a constant frequency or digital signal.

Here, the authentication data extraction unit 13 of the security equipment system 2 demodulates the data sent from the terminal 1 to extract only the authentication data and then outputs the authentication data to the authentication processing unit 14. Then, the authentication processing unit 14 compares the authentication data extracted by the authentication data extraction unit 13 with the authentication data stored in the authentication data storage unit 12 to determine whether to authenticate. At this time, if the authentication data transmitted from the terminal 1 in the process is authenticated, the security equipment system 2 drives the actuator 15 to open the door of the security device, for example, the car opening and closing system or the Internet authentication system or the door opening and closing system. Open it.
