Description

Mobile communication terminal using USB port

The present invention relates to a mobile communication terminal, and in particular, by applying a USB port to the mobile communication terminal, it is possible to give compatibility with various home appliances such as personal computers, other information devices and digital cameras, and maximize the function as a personal information terminal. The present invention relates to a mobile communication terminal employing a USB port.

In general, a mobile communication terminal is one of wireless communication devices that can be miniaturized for easy portability and can be used for communication or data exchange with a counterpart without being limited to a location and a distance within a radio wave emission distance of a base station. With the development of the Yosai industry and the pursuit of the information society, its spread as one of the important personal communication means continues to spread.

1 is a block diagram of a general mobile communication system.

As shown in Fig. 1, the mobile station (mobile communication terminal) 1 communicates with the base station 2 wirelessly, and in particular, a mobile call is possible. The base station 2 communicates with the mobile station 1 wirelessly under the control of the control station 3, and the control station 3 controls the base station 2. The exchange station 4 switches the signal transmitted from the mobile station 1 to another station or another communication network, and switches the signal transmitted from the other station or another communication network to the mobile station 1 side.

Here, the mobile communication terminal, which is the mobile station 1, is a communication system for a mobile object such as a person, a car, a ship, or an aircraft, which includes a personal communication system (PCS) and a digital cellular system (DCS; Digital). Trunked Radio System), Digital Trunked Radio System (DTRS) and IMT-2000 are used.

2 is a perspective view of a general mobile communication terminal of FIG. 1.

As shown in the figure, an LCD unit 20 for outputting data input state is provided on the front of the body 10, and a phone number and other additional functions are inputted under the LCD unit 20. The keypad 30 is provided to the upper and lower ends of the body 10, and a receiver 40 and a transmitter 50 are respectively provided, and the keypad 30 is provided at both lower sides of the body 10. One end of both sides of the flip 60 is hinged to open and close), and a torsion spring (not shown) is installed at the hinge portion of the flip 60 to elastically open and close the flip 60. have.

Therefore, when the mobile communication terminal is used, when the flip 60 is folded, the two sides of the free end of the flip are grasped and pulled outwardly of the body 10 so that the flip 60 rotates clockwise around the hinge axis to about 180 degrees. The keypad 30 is exposed while being opened by °, so that the phone number and data can be entered.

On the other hand, when the mobile communication terminal is not used, when the free end of the flip is pushed toward the body 10 while the flip 60 is unfolded, the flip 60 rotates counterclockwise around the hinge axis to the body 10. While being in close contact with the keypad 30, the portable state becomes possible.

3 is a perspective view illustrating a bottom surface of the mobile communication terminal of FIG. 2.

As shown in the figure, a car kit 70 for transmitting and receiving data through a computer (not shown) is installed on the bottom of the mobile communication terminal.

The car kit 70 is used in combination with a lighter jack (not shown) of the vehicle for battery charging.

Figure 4 is a block diagram showing a block configuration of a mobile communication terminal capable of direct wireless data transmission between the general terminal.

As shown, the mobile communication terminal 100 includes: a mobile station modem chip (MSM chip) 110 for controlling overall operations of the terminals and controlling direct wireless communication between the terminals; A speaker 120 for outputting an audio signal; A microphone 130 for inputting a voice signal; A keypad 140 for receiving a user's key manipulation for short-range wireless communication; An LCD (Liquid Crystal Display) 150 for displaying a state, data, etc. of the terminal to the user under the control of the MSM chip 110; The PCM (Pulse Code Modulation) data digitally processed by the MSM chip 110 is converted into analog data and output to the speaker 120, and the analog voice data input from the microphone 130 is digitally processed. A codec (160) for transmitting to the MSM chip (110); Memory 170 for storing information that can be stored in the terminal, such as information about the terminal user, personal address book; An RF processor 180 radiates the digital data processed by the MSM chip 110 to a base station system by radio frequency (RF) processing.

However, the conventional terminal, for example, to share all information that can be stored in the terminal, such as MP3 (MPEG Audio Layer3) files, Web data, etc. between the terminal, using the PC as an intermediate medium through the car kit or base station We had to connect to the network through the system. In this case, the terminal user is not only inconvenient to use, but also causes a lot of economic and time loss.

The car kit also allows data to be transferred to or from a computer or laptop, but it had to purchase additional hardware. This also caused expensive problems.
