    Apparatus and method for service in mobile terminal using computer}
    [11] The present invention relates to a service of a wireless subscriber network terminal, and more particularly, to a service apparatus and method of a wireless terminal to implement a voice service and a data service using a sound card of a PC.
    [12] 1 is a configuration diagram of a conventional terminal and a peripheral device, and as shown therein, an RJ-45 jack (type of connector) or a universal serial bus (USB) between a PC (or personal computer) and a terminal. Serial communication bus standard) port (port), and the general wired telephone line between the terminal and the normal landline phone to use the service.
    [13] FIG. 2 is a structural diagram of a conventional terminal, and as shown therein, the structure of the terminal is largely divided into three types: a radio frequency (RF) unit 10 and a mobile station modem (MSM) (or Application Specific Integrated Circuit (ASIC) modem unit 20, power supply unit 32, Subscriber Line Audio-processing Circuit (SLAC) 34, Subscriber Line Interface Circuit (SLIC) 36, SIO ( There is a baseband processing unit 30 consisting of a Serial In Output (38).
    [14] The high frequency unit 10 demodulates the signal received from the antenna, and the mobile station modem (or AI modem) 20 transmits the demodulated signal from the high frequency unit 10 to the baseband processor 30.
    [15] The signal transmitted to the baseband processing unit 30 is controlled by the mobile station modem (MSM) 20 and appropriately controlled according to the mode of the terminal, and then passed to each stage.
    [16] In the case of a voice call, it is finally connected to the user's phone via the SLAC 34 and the SLIC 36, and the SLAC 34 and the SLIC 36 are disabled when in a data service such as WAP. It is delivered to the PC via an LCD (Liquid Crystal Display) or Serial In Output (SIO) 38.
    [17] It also communicates via USB port when the data rate is 144Kbps or faster.
    [18] As described above, the voltage for driving the SLIC needs to be + 5V, -64V, and -24V, and the ring voltage specifications required by each country must be met. Due to the high cost of SLIC and SLAC, the material cost of the terminal increases. Using a PC and a phone separately causes inconvenience.
    [19] Accordingly, the present invention has been made to solve the above problems, and has an object of implementing a voice service using a sound card of a PC while implementing a data service on a PC.

    [20] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
    [21] Service device for a wireless terminal using a PC applied to the present invention,
    [22] The voice service of the terminal enters the serial port of the PC through the interface to make voice calls, and the data service of the terminal is displayed on the LCD, and the data of the terminal enters the other serial port of the PC through the connector. You can download it.
    [23] The terminal,
    [24] A high frequency part demodulating the signal received from the antenna:
    [25] A mobile station modem for transmitting the demodulated signal of the high frequency unit to a baseband processor;
    [26] Power supply unit for supplying power to the terminal,
    [27] And a baseband processor comprising a serial input / output port for transmitting and receiving demodulated signals transmitted from the mobile station modem.
    [28] The voice service uses a sound card built into the PC.
    [29] Service method of a wireless terminal using a PC applied to the present invention,
    [30] Delivering voice service data to the mobile station modem (MSM); connecting to the UART, PC serial port, and PC sound card in the case of voice service; and downloading other data other than voice service to the PC when not in voice service. If the UART, the PC is connected to the USB port order, and the data service is displayed on the liquid crystal (LCD) when not downloading to the PC.
    [31] 3 is an installation configuration diagram between a terminal and a peripheral device applied to the present invention, and FIG. 4 is a structural diagram of the terminal applied to the present invention.
    [32] The data transmitted to the mobile station modem (MSM) 20 through a radio frequency (RF) 10 is a synchronous digital signal, each of which enters the PC via RS-232C when the terminal is in a voice call mode. In Short Message Service (SMS) mode, it is delivered to the LCD of the terminal.
    [33] In addition, when downloading to the PC enters the PC through the UART (Universal Asynchronous Receiver Transmitter).
    [34] Accordingly, in the mobile station modem (MSM) 20, it is necessary to reorder the data for transmitting the data according to the operation mode of the terminal after demodulating the I / Q signal received by the radio frequency (RF) 10.
    [35] In addition, the method of transmitting the voice signal to the PC through RS-232C is 8 bits when the voice modulation method is PCM (Pulse Code Modulation) when the voice call is in progress, and the ADPCM (Adaptive Differential Pulse Code Modulation) 4 bits.
    [36] The data is transmitted to the asynchronous RS-232C.
    [37] In this case, in order to transfer the synchronous data down to the maximum 64Kbps to the PC by RS-232C method, an operation speed of 64Kbps or more is required. In this case, a high speed data RS-232C driver IC is used and the corresponding PC is used. If you use the Windows 98 or higher operating system, the serial port of the PC can be supported up to 144Kbps or more, so it can operate smoothly.
    [38] The sound card built into the PC allows the speaker and microphone to make voice calls and maintain data services.
    [39] Thus, the telephone for the voice call is unnecessary, and various circuits for supporting the landline telephone are eliminated.
    [40] At the same time, it uses data service and voice service on PC.
    [41] 5 is a flowchart illustrating a service method of a terminal applied to the present invention.
    [42] After the voice service data is transmitted to the mobile station modem (MSM) 20 via the high frequency (RF) 10, the voice service is performed in the terminal, and then connected to the UART, the PC serial port, and the PC sound card. (S10 to S18). )
    [43] If other data other than voice service is downloaded to PC when not in voice service, it is connected to UART or PC USB port. (S20 ~ S24)
    [44] When data other than a voice service is not being downloaded to the PC, that is, when a short message service (SMS) is in operation, the LCD is driven to display the short message. (S26, S28)
    [45] As described above, according to the present invention, by implementing the data service and the voice service in one PC, the user can easily use two types of services, and restore the voice signal through the sound card stored in the PC. You can make good calls and use various services built in to the sound card.
    [46] In addition, it is possible to conveniently use the function extension service by using an application program through the connection with the PC, and to eliminate the SLIC and SLAC ICs, thus reducing the cost of material costs as the supply power of the two ICs is unnecessary.
