BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable terminal device. In particular, the Windows series or the Macintosh of MicroSoft used by a general-purpose computer (for example, a desktop, a laptop computer, etc.) rather than an operating system (OS) dedicated to the portable terminal device. The present invention relates to a portable terminal device operating in an OS such as Mac OS and Linux.

The portable terminal device is meant to include various terminals such as mobile communication terminals, personal digital assistants (PCS), personal digital assistants (PDA phones), smart phones, next generation mobile communication terminals such as IMT-2000 and 4G mobile phones.

In the related art, in order to implement a GSM or CDMA communication terminal, call processing software (SW) for the communication method is mounted in an ASIC in a mobile terminal device such as a mobile communication terminal or a PCS. A function may be implemented or a module including a mobile communication function that does not include a user interface (UI) in an expansion slot, such as a PDA, or the like.

1 is a block diagram of an embodiment of a conventional mobile communication terminal.

As shown in FIG. 1, a conventional mobile communication terminal includes about one baseband ASIC 100 dedicated to a mobile communication terminal (in the ASIC, a general CPU 102 and a DSP processor 104 dedicated to arithmetic processing are included together). And a dedicated RF / analog circuit 110, a user interface (UI) circuit 120, a power circuit 130, and the like, for a mobile communication terminal only.

The two processors embedded in the baseband ASIC 100 operate with distinct functions. That is, communication protocols (e.g., CDMA call processing SW, etc.) and general application SW (e.g., UI SW, etc.) are processed by the general CPU 102, and during voice calls, encoding and decoding, and modems Related functions and the like are mainly processed in the DSP processor 104.

In this case, the two processors 102 and 104 require a portable terminal device-specific OS (eg, a Symbian OS) in the baseband ASIC 100 due to the need for using the common memory 140, and the portable terminal device. Dedicated OS is quite different from OS used in general PC so that all HW operation and SW can be processed efficiently in mobile terminal environment (relatively small memory and small UI device compared with general PC). And it is implemented in the form having the characteristics.

2 is a block diagram of an embodiment of a conventional PDA.

As shown in FIG. 2, the conventional PDA processes all SW processing such as call processing and UI application required for a wireless call in the mobile communication module unit on the portable terminal device dedicated OS 200, and the result (voice and UI). If only data) is sent to the PDA unit, the PDA unit is driven by sending a voice to the microphone, speaker, etc. of the PDA 210, and sending UI related data to the UI 220 of the PDA.

In other words, all call processing SWs and application SWs operate independently on the OS 200 dedicated to the mobile terminal device in the mobile communication module unit, and all the necessary memories use the dedicated memory 230 in the mobile communication module unit, and the PDA company. The PDA unit and the mobile communication module are connected through an interface method agreed between the mobile communication module developers before the development progress. That is, the PDA mobile communication module and the PDA unit exchange only the final processed audio signal and data and control signal.

The commonalities of the mobile terminal devices such as the mobile communication terminal and the PDA in the above-described manner are to install the OS SW (for example, Symbian) for the mobile terminal device in the core component in the hardware (HW) board dedicated to the mobile terminal device. Call processing SW, UI SW, and various application software running on the system are installed and executed.

That is, conventionally, the mobile communication SW (eg, call processing and UI SW, etc.) required on the portable terminal device dedicated OS is implemented / operated. When the portable terminal device dedicated OS is used, this is the internal environment of the portable terminal device. Since the OS is optimized to fit the HW and SW operation, the portable terminal device can be made compact, lightweight, and low power.

However, the OS dedicated to the portable terminal device has a disadvantage in that the limited performance of the portable terminal device itself is limited due to the limited environment (for example, high cost, small memory, and small UI device).

The present invention is a Windows OS series, Mac OS series, Linux, etc., which are used by general-purpose computers (eg, desktops, notebook computers, etc.) using conventional portable terminal devices implemented by dedicated hardware and software on a portable terminal device dedicated OS. The purpose of the present invention is to provide a portable terminal device operating on a computer OS that implements the portable terminal device hardware at a lower cost and enables the user to develop / apply an application software SW for the portable terminal device. have.

In addition, the method for registering for a call of a mobile terminal device operating on a computer operating system,

A secondary active window for inputting personal usage information suitable for the designated communication method is displayed, and the personal usage information of the user is input through a user interface of the computer, and whether the user is an effective subscriber through the input personal information. Requesting confirmation of whether the base station and the system; Displaying a mobile phone function available message on a computer screen if the user is identified as a valid subscriber by the system, and awaiting further selection by the user; If it is confirmed that the user is an invalid subscriber, displaying a personal information reconfirmation message on a computer screen, requesting reentry of personal information of the user, and requesting reconfirmation from the base station and the system; If it is confirmed that the user is an invalid subscriber even if the re-entry and re-confirmation of the personal information is repeated several times, it is characterized in that it comprises the step of requesting to switch to another communication method.

In addition, a method of calling a counterpart via a mobile terminal device operating on a computer operating system,

Selecting a dialing mode through a menu of an active window displayed on a screen of a computer; A user inputting the other party's telephone number and a service option through a user interface of the computer; Call origination message, phone number and selected service by call processing program in driver software (SW) for each communication method (for example, WCDMA driver, CDMA driver, etc.) operating on the operating system (OS) of the computer Transmitting a selection or the like to the base station; When the call channel is allocated from the base station and the ring tone of the other party is received, a message connected to the call is displayed on the screen of the computer, and the ring tone is output to the speaker of the computer; A user's voice is input through a microphone of a computer, processed into digital data, and then converted into a format according to an audio codec defined by a selected communication method and transmitted to a counterpart via a base station; The voice data transmitted from the other party is input in the form of an audio codec suitable for the communication method, and the format is converted into a form suitable for the sound card of the computer, characterized in that it comprises the output to the speaker of the computer.

In addition, a method for receiving a call from the other party through a mobile terminal device operating on a computer operating system,

When a call is received from the other party, the system message channel (for example, paging channel of CDMA) transmitted from the base station is continuously received by the control of the software driver for the designated communication method, and the system message is formatted and data framed by the HW module. Transmitting; When the SW module analyzes the data frame and confirms that there is a system message indicating that the call came by comparing and checking the stored personal information, check the other party's telephone number, and display the telephone number and the other party's telephone number on the computer screen. Generating a ring tone through the speaker, and displaying an active window of call connection and call release; When the user selects a call connection, a call channel is allocated from the base station, and a speaker and a microphone connected to the computer are connected to the user to make a voice call.

In this case, when the user selects the call release, the mobile station sends a request for rejecting and releasing a call currently being received to the base station, and releases the call after sending and receiving a related message as defined in the communication method with the base station. The method further includes controlling the speaker to be used for other application software of the computer.

In the method for making and receiving a call according to the present invention,

Characterized in that it comprises a step controlled to.

That is, the main difference between the present invention and the conventional portable terminal apparatus is that the main application SW in the conventional portable terminal apparatus does not operate on the baseband asic and the memory chip in the mobile phone, but operates on the OS and memory of the general-purpose PC. .

According to the portable terminal device operating on the computer OS according to the present invention, since the stable and open OS used for the general purpose computer is used, the limitation of the performance implementation inevitably possessed by the mobile phone-specific OS and the user's own application SW It can overcome the disadvantage that can not be put in the design.

In the case of OS used for general purpose PC, a large number of application SWs have already been developed and distributed in the market, and many SW tools necessary for developing such application SWs have already been developed, and also the use of abundant memory of the PC This is because it is possible to overcome problems such as operation error of personal application SW due to insufficient memory when implementing the user's own SW.

Accordingly, the user can easily develop and use the application SW necessary for his mobile terminal device directly, and the user can directly program the application SW for the mobile terminal device for himself or herself, so that the user can customize his / her own personal preference. You may be able to configure your own UI.

For example, you can choose graphics and resolutions, configure your keyboard layout to your own, and choose from a variety of widely used pictures, videos, music, and more to suit your needs. It can be used as a video.

In addition, in terms of hardware, since the configuration of the board connected to the outside is composed of the minimum RF circuit and the minimum baseband components, the cost of the HW board is lower and the reliability is improved. This is simpler and less likely to occur.

In addition, by using the advanced UI (eg, monitor, keyboard, speaker, microphone) of the general-purpose computer, and using the large-capacity memory of the general-purpose computer, it is possible to configure external HW at a low cost by significantly reducing expensive components.

In the conventional case, the most expensive components in the implementation of the portable terminal device are enormously integrated baseband asic, memory, color LCD, and battery. According to the present invention, since these expensive components can be used in almost all of ordinary PCs, the portable terminal apparatus can be implemented using only inexpensive components with much fewer components than those necessary for the production of portable terminal apparatus HW. .

In addition, in terms of SW, there is an advantage in that a service that is almost impossible in the conventional case, that is, a user can provide a service for developing a mobile phone SW to a mobile terminal device user.

In other words, it becomes possible to provide a differentiated service providing HW configuration and SW of a mobile terminal device having a completely different concept.

In addition, there is an advantage that a call can be simultaneously performed during a PC operation even without a separate portable terminal device from the PC.

Differences between the present invention and the conventional portable terminal device will be described in more detail with reference to the accompanying drawings.

3 is a block diagram schematically showing the configuration of a portable terminal device operating on a PC OS according to the present invention.

The difference between the portable terminal device and the conventional portable terminal device according to the present invention will be described with reference to FIGS. 3 and 1 and 2 as follows.

Baseband processing chips (100, 200) provided in conventional mobile terminal devices generally include a microprocessor, digital signal processing (DSP), and multi media processor for multi media data (MMP, for example, video recording and voice recording. For data processing, etc.) are implemented together in one chip, which is made of integrated circuit (IC) of high density.

In addition, since a dedicated circuit for communication protocol (CDMA, GSM, WCDMA, etc.) is additionally included, the baseband processing chip (100, 200) is the most complex and power consumption inside the conventional mobile terminal device Also corresponds to many parts.

On the other hand, the BBP (Basic / Simplified Baseband Processing chip) 300 shown in FIG. 3 removes the microprocessor, MMP, etc., which may be the most complicated part, and the DSP is replaced with a lower grade having a much simpler function. In addition, the size of the built-in memory for the DSP is greatly reduced.

In addition, since a dedicated circuit for processing a communication protocol is mounted together, circuit complexity can be greatly reduced, and power consumption can be greatly reduced.

This is possible because all functions handled by the microprocessor and the MMP are handled by the MMP and the co-processor part in the general PC 310.

Therefore, since only the DSP processor to handle only relatively simple tasks is embedded in the BBP 300, the size of the memory 320 required for this is small and the performance of the DSP can be used without the need for high performance.

In other words, by significantly reducing the performance requirements of the baseband processing chip as a key part of the conventional mobile phone technology and simplifying it, the circuit can be simplified and lowered in cost.

In addition, since there is no processor and a memory in which the call processing SW, the application SW, the user interface (UI) SW, and the like can be processed, the SWs are the processor and the memory 330 of the PC 310. Must be handled within

Accordingly, the call processing, the application, and the UI SW of the present invention are all changed to be operable on an OS (Window-based OS, Mac OS, Linux) such as a general PC (Desk top, Notebook), and this is the most similar to the conventional one in terms of SW. That's a big difference.

The portable terminal device operating on the PC OS according to the present invention is largely composed of a hardware (HW) module and a software (SW) module.

In this case, the HW module may be implemented by inserting a general PC (desktop or notebook PC, etc.) in the form of an internal card, or may be implemented in an external form connectable through an external interface (USB, IEEE1394, etc.) of the PC. In the case of may be implemented in the form of a module inserted into the PCMCIA slot.

In addition, the SW module is implemented in a form that operates on an OS (Linux, Windows-based OS, Mac OS, etc.) of a general PC (Personal computer).

4 is a block diagram illustrating an embodiment of a portable terminal device HW module according to the present invention.

Referring to FIG. 4, the HW module of the portable terminal device according to the present invention includes a wireless circuit unit 400, that is, an RF transmitter 402, an RF receiver 404, a frequency synthesizer 406, a power circuit 410, The analog circuit unit 420, the control circuit unit 430, and the PC interface unit 440 are included, which are coupled to the PC 450 through the interface 452.

The HW module is mainly responsible for part of the first and second layers (Layers 1 and 2) of the communication protocol, and in some cases under the control of the SW module, the form of the output frame sent from the HW module to the SW module is Can be changed.

That is, in the case of the voice signal, data such as demodulation, error detection and restoration, and voice decoding are basically outputted to the HW module and transmitted to the SW module, but if necessary, the SW module sends control commands to the HW module. When sent, output that is not performed for voice decoding may be framed and transferred to the SW module.

Hereinafter, the functions of the main parts of the HW module will be described.

First, the RF transmitter 402 in the wireless circuit unit 400 transitions the baseband analog signal input from the analog unit 420 to a desired radio frequency band to enable long-distance transmission. The receiver 404 serves to convert the radio information received from the desired radio frequency band into the base band and input the analog information to the analog unit 420.

In addition, the frequency synthesizing unit 406 functions to precisely synthesize (synthesis) the frequency required by each of the RF transmitter 402 and the RF receiver 404 to the required portion.

In addition, the analog unit 420 converts the digital signal input from the control circuit unit 430 into an analog signal and inputs the RF signal to the RF transmitter 402, and converts the analog signal input from the RF receiver 404 into a digital signal. It performs a function to change the control circuit unit 430 to enable processing. In addition, it works with RF unit to adjust the overall gain of the circuit (automatic gain control) and to perform its own performance compensation and compensation (Compensation & Calibration) of each circuit.

In addition, the power supply circuit unit 410 functions to supply power of various standards required by each part in the HW module.

The control circuit unit 430 performs arithmetic processing and control necessary for performing automatic gain control, calibration, and compensation of the analog circuit unit 420 and the RF circuit units 402 and 404. It transmits the function to give the command to each part and the frequency information necessary for the frequency synthesizing unit 406, and processes according to the communication standard (Common Air Interface) for each communication method (GSM, WCDMA, CDMA2000, etc.) designated by the SW module ( Modem, Error correcting codec, Voice Codec, etc.)

That is, the control circuit unit 430 processes the digital signal input from the analog unit 420 by a predetermined communication method program downloaded from the SW module (demodulation and error detection and correction of an RF received signal, and restoration of voice information). And other data information to be framed into processed data and then transmitted to the SW module, and analyzes the data frame received from the SW module to extract the data to be transmitted and processes necessary (Voice encoding, modulation and Error Encoding for Error Correction, etc.) and then transmits the data through the RF transmitter 402. Such a control circuit unit 430 may be generally implemented by a DSP (Digital Signal Processor) processor.

In addition, the interface unit 440 includes a circuit for connecting the HW module to the general PC 450 and has a function of transmitting information of the HW module to the general PC 450, and the information of the general PC 450 is HW. It connects so that it can be delivered to the module.

At this time, when the HW module is in the form of an internal card, it functions to connect with a bus inside the PC, and when it has a form of PCMCIA, it satisfies the PCMCIA connection standard. The same applies to.

Next, the SW module of the mobile terminal device according to the present invention will be described.

The SW module operates on the OS of the general PC 450 and is responsible for processing a part of the second layer (Layer2) and the third to seventh layers (Layer3-7) of the communication protocol, and manages its own menu by the UI of the PC. It receives and processes the user's requirements.

The SW module functions to control the HW module according to the present invention according to a user's request input using a UI (User interface: Mouse, Keyboard, Display, touch screen, Mic, Speaker etc) of the PC 450 for this purpose. And a function of storing personal information of a user input by the user, a function of downloading information necessary for the HW module (a communication program and a personal information supporting a specified communication method), and a counterpart inputted from the HW module. Upload and process the information and provide it to the user through the UI of the PC, and send the user's various information input from the PC's UI (keyboard, etc.), microphone, PC camera, etc. to the other party using the HW module. It has a function to make.

5 is a diagram showing the structure of data transmitted and received between the HW module and the SW module of the present invention.

The HW module and the SW module exchange data in a frame structure as shown in FIG. 5 for efficient data transmission and processing.

When the framed data is received, the frame number 510 is first checked to determine whether the frame is continuously received without losing the frame, and at this time, the frame is requested to be retransmitted.

Also, by analyzing the type of the frame currently received through the type field 520 of the main data, it is determined whether there is valid data in the main data field, and when the presence of the valid data is recognized, the nature of the data (for example, an image). Data, voice data, etc.) and their lengths are processed. Since the control command has to be urgently processed, the control command and status report data field 530 are analyzed immediately.

The control command and status report data field 530 may also include a main data field processing method, and various call processing-related messages that the SW module exchanges with a base station or a system in connection with call setup, call termination, call release, etc .; Internal status report (self-diagnosis result, calibration & compensation result, base station related information, etc.) information of HW module may be included or information such as BER and FER.

Since the control command and status report data field 530 includes main information, a CRC field 540 is added to overcome the error, and the main data field 550 thereafter contains a large amount of data (hundreds of thousands of bytes or more). There is no check of CRC as it is exchanged. EOF 560 serves to signal the end of the frame.

The SW module is composed of a basic operating program and a library program for each communication method, and the basic operating program has a function of managing a main active window, a related menu, an auxiliary window, and a related menu displayed on a screen.

By activating the basic operating program of the SW module on the OS of the PC, the user determines the communication method to be used by the active window presented by the basic operating program. After reading the driver SW for each communication method and downloading the necessary parts of the HW module from the read driver SW, after the self-check of the HW module is completed, the user can operate the mobile phone function on the OS of the general PC. , display, key board, etc.) can be used.

Here, the library program for each communication method includes a separate call processing program (CDMA call processing, WCDMA call processing, GSM call processing program, etc.) for each communication method (GSM, CDMA, WCDMA, etc.), UI SW (CDMA, WCDMA, etc.), Application SW (for GSM, WCDMA, etc.), encryption programs, and interface programs, the five types of programs are read together for each communication method when reading from the library. Programs do not differ by communication method, so they can be shared.

That is, when the user decides the communication method to be used in the activated window, the relevant operation program (call processing, UI, interface, encryption, various application SW, etc.) for the selected communication method is read from the library of the communication method program and operated. do.

At this time, since the program contents required for call processing are different for each communication method, the call processing SW program for each communication method is read, and in addition, UI SW program, application SW program, external interface SW program, and user's personal information. And an encryption program for encrypting information requiring security, and the like, are libraryed for each communication method. In addition, when the communication method is determined by the user, corresponding and necessary programs are read from the library, and all these operations are run on the OS of the PC.

In addition, the program downloaded by the SW module to the HW module, the program responsible for the control and status management and resource management of the entire HW module, and the self-diagnostic function and analysis SW and RF control program (for example, automatic gain It is a program that manages functions such as AGC / Calibration / Compensation and other control necessary for RF circuit during normal operation) and the frequency information necessary for RF frequency synthesizer. And a program including SW for a searcher, an audio codec, a modem, and an error correcting codec.

Fig. 6 is a diagram showing that a communication method is designated in the mobile terminal device of the present invention.

In the case of the present invention, since most wireless connection standards are processed in SW in a DSP chip in the control circuit unit 430 of the HW module, if an RF transmission circuit of an IF method or a direct conversion method is used, the DSP chip is used. By downloading SW, user can decide and use communication method (eg GSM, CDMA, WCDMA, etc.).

However, this is only one embodiment of the present invention, and the present invention is not limited thereto.

When the user activates the SW module of the present invention through the UI of the PC, the main active window is displayed on the screen, and menus necessary for the user are presented. (ST 501)

When the user selects a communication method from the menu, the communication methods available through the auxiliary active window are displayed with a check box so that the user can select a desired communication method (eg, GSM, WCDMA, CDMA2000, 4G, etc.). Selects a specific communication method and stores the selected information (ST 502)

In this case, the driver SW instructs only the self-analysis test of the HW module without performing downloading of the communication method program for the HW module if the communication method designated by the user is the same as before, and the test result of the self-analysis test is transmitted to the HW module. Receives a message from the user and displays the result on the screen. (ST 503, 504)

If the previously used method and the current communication method selected by the user are different, the communication method program for the HW module is downloaded to the HW module and the HW module is commanded to detail the analog circuit part and the RF part in the HW module. Instruct them to carry out their own calibration and compensation of the parameters, perform their own performance tests, and notify the SW module of the results. (ST 505)

Therefore, the HW module notifies the SW module that there is no abnormality if the test result is not abnormal after executing the command, and if the abnormality is notified to the SW part of the abnormal part, then waits for the control of the SW. (ST 506, 507, 508)

The SW unit displays an error history to the user when there is an error, and displays an active window for recommending the use of another mode or requesting termination of use.If there is no error, the SW unit displays an error on the screen. Wait for the next choice. (ST 509, 510, 511)

In addition, when there is no error, the HW module prepares an operation by sending information (for example, frequency or information) necessary for the analog circuit unit and the RF unit in the HW module. (ST 512)

7 is a diagram illustrating a registration process in the mobile terminal device of the present invention.

However, this is only one embodiment of the present invention, and the present invention is not limited thereto.

When the user activates the SW module of the present invention through the UI of the PC, the main active window is displayed on the screen and the menus necessary for the user are presented in the main active window.

When the user selects terminal registration from the menu, a sub-activation window for entering personal information is displayed and the user inputs personal information (eg, electronic serial number, such as ESN). The received personal information is messaged as required by the user-specified communication method and sent to the system, that is, the base station, through the control unit of the HW module, and requests confirmation of valid subscribers. (ST 701)

When the base station checks the valid subscriber through its DB (VLR, HLR) and transmits the result in the form of a message, the HW module restores the data through the RF receiver, the analog circuit, and the control circuit and frames the SW module. To send. (ST 702)

The SW module analyzes the received message from the base station and displays the mobile phone function available on the screen when receiving the valid subscriber notification and receives the user's confirmation through the UI.If the user confirms, the driver of the selected communication method with the HW module The SW switches to the idle state and waits for the next selection of the user. (ST 703, 704)

If you receive notification from the system that you are an invalid subscriber, you are an unregistered subscriber, request reconfirmation of personal information, activate the window to re-enter personal information, and re-enter personal information after re-entering personal information. Requests the system to send and confirm (ST 705)

 When the base station and the system transmit the confirmation result for the personal information to the SW module through the RF receiver, analog unit, and control unit of the HW module, the driver SW in the SW module analyzes it. If the same result is found again, repeat the above process several times, activate the auxiliary window requesting the switch to another mode (e.g. GSM-> CDMA), and when the user selects another mode through the check box, SW library Read the call processing program and related application SW of the relevant mode from the mode and prepare for the next operation.

After that, the process is repeated again. That is, after receiving the personal information input in the selected mode and the subsequent process is the same as above, if the base station notifies that the valid subscriber, the mobile phone function available on the screen and the user's confirmation is input through the UI of the PC, When the user enters it, it switches to the idle state and waits for the user's next choice. (ST 706)

The present invention can be repeated from time to time according to the type and procedure of registration prescribed by the selected base station or in accordance with the occasional registration request of the system.

8 is a diagram illustrating a procedure for making a call through the mobile terminal device of the present invention.

However, this is only one embodiment of the present invention, and the present invention is not limited thereto. The dialing process operates in the communication method selected by the user (eg, WCDMA, etc.) after the driver SW of the selected communication method operating on the OS of the PC confirms that there is no problem in the registration process.

Referring to FIG. 8, first, when a user selects a call through the main menu provided by the selected communication method driver SW of the SW module, the auxiliary window is activated.

In other words, the user is provided with an auxiliary active window and a check box for inputting a phone number and selecting a related service using the PC's UI, and receives the user's input and options through the UI of the PC. (ST 801)

When the user selects and inputs the phone number and service option, the call processing program in the selected communication method driver SW operating on the OS of the general PC displays the call origination message, the phone number, and the selected service option. Through the HW module, it transmits to the system, that is, the base station, and then sends and receives messages related to the system and the call setup. (ST 802)

Through this, when a call channel is allocated from the base station and a ring tone of the other party is received, a message connected to the call is displayed to the user through the UI of the PC, and the ring tone received through the speaker connected to the PC is output. (ST 803)

In addition, the auxiliary active window displays a check box for selecting an additional call termination and waits for user selection. Then, the speaker and the microphone connected to the PC to control the driver SW of the present invention until the end of the call to continuously make the call. (ST 804, 806)

When the user selects a check box in the active window, the call duration time, connected number, and related service options are displayed on the screen, and the call termination message is transmitted to the base station. Send through the module and complete the call termination procedure with the base station and system. (ST 805)

In this series of processes, the HW module performs the same functions as the modem for user information (voice or image information) and messages that the driver SW sends and receives to and from the system (i.e., in a manner that satisfies the Air Interface specification according to the specified communication method). All messages sent to and received from the base station are analyzed by the driver SW running on the OS of the PC and then responded to the system through the HW module.

In this case, the user's voice is input through a microphone connected to a PC, processed into digital data by the sound card, and if necessary, the format of the audio codec (encoder / decoder) specified by the communication method selected by the driver SW is required. (E.g., QCELP in the case of CDMA), the frame is converted and sent to the HW module as shown in FIG.

The audio information transmitted from the other party is RF received by the HW module, demodulated and corrected by the control circuit, and after calculating the bit error rate or frame error rate, the audio codec type suitable for the current communication method (eg QCELP). 5) and then framed in the form shown in FIG. 5 and transmitted to the driver SW of the SW module in the PC, and if the driver SW is needed, the speaker after the form conversion (codec format translation) suitable for the sound card of the PC Tell the user via

In this regard, an exemplary embodiment of a call answering process through the mobile terminal device according to the present invention will be described below.

9 is a diagram illustrating a call receiving process through the mobile terminal device of the present invention. However, this is only one embodiment of the present invention, and the present invention is not limited thereto.

When a call is received from the other party, the HW module continuously controls a channel through which a base station sends a system message by controlling a communication driver SW driver (eg, CDMA Driver, WCDMA Driver, etc.) selected by the SW module. The message is received, formatted, framed, and sent to the driver SW (ST 901).

 When the driver SW analyzes the received data format and confirms that the base station is calling the phone number in the personal information that is already stored, that is, the user's phone number, the driver SW additionally activates the active window to the user in the window. The UI shows the caller's call, the caller's phone number, and shows two check boxes of call connection and call release. (ST 902, 903)

In addition, the driver SW generates a user-specified ringtone through a speaker connected to the PC through a sound card of the PC so that the user can recognize the call. When the user selects a call connection, the driver SW sends a call connection message. Sending to the base station is assigned a call channel, and the speaker and microphone connected to the PC to the user to enable the call. The control of the speaker and microphone after (ST 903, 904) is the same as in the above-described dialing.

In addition, when the call is connected, the secondary active window displaying the call connection is closed, and the secondary active window showing a new call termination check box is newly activated, waiting for the user's selection. (ST 905)

Here, if the user does not select the end of the call, the call is maintained (ST 906), and when the user selects the end call check box to terminate the call, a message for ending the call is sent to the base station and the call is made with the base station and the system. All procedures for termination shall be carried out as specified in the communication method.

At this time, upon receiving the final notification of the end of the call from the base station, close the current auxiliary active window, activate the auxiliary active window displaying the usage time, the counterpart phone number, etc. do. (ST 908)

If the user selects a call release, the user sends a request for rejection and release of a call currently being received to the base station, and releases the call after transmitting and receiving a related message as defined in the communication method with the base station. (ST 907)

When the base station receives the message 'Disabled call', the microphone and speaker are re-controlled so that other application software on the PC can use it. (ST 908)

According to the portable terminal device operating on the computer OS according to the present invention, a portion of the HW module corresponding to the portable terminal device can be manufactured more cheaply and more reliably than the conventional method, and the memory in the PC is richer than the conventional portable terminal device. By utilizing UI elements, a more user-friendly and convenient UI can be realized, and mobile phone users can devise and implement their own application SW.

This is because most of the important SWs operate in the OS of general PCs, and through this, the user can modify and improve some of the UI and application SW of the mobile terminal device according to his / her personality. By using the mobile phone function according to each communication method can be implemented and used in a general PC.
