    Personal digital assistant with built-in communication module {Personal digital assistant having a inner RF module}
    [8] The present invention relates to a personal information terminal such as a personal digital assistant (PDA), and more particularly, to a personal information terminal having a built-in communication module (RF Module) for connection connection with a mobile telephone network.
    [9] FIG. 1 schematically shows an overall configuration of a general personal information terminal. The personal information terminal 100 such as a PDA includes an audio codec 10, a CPI 11, a companion chip 12, In addition to the video controller 13, the LCD 14, and the like, various extension packs such as an RF module 15 may be connected and connected.
    [10] On the other hand, the communication module 15 is connected to a mobile telephone network such as a code division multiple access (CDMA) or a global system for mobile communication (GSM) and the like through a wireless connection through an antenna (ANT.) Thus, to perform a phone (Phone) function.
    [11] And. In the audio codec 10, after processing a user's voice signal received through a microphone (MIC) embedded in a personal information terminal as audio data, the CPI 11 and the companion chip 12 communicate with each other. The communication module 15 outputs the audio data to the module 15. The communication module 15 converts the audio data into voice data and wirelessly transmits the data through the mobile telephone network.
    [12] In addition, the communication module 15 outputs voice data received wirelessly through the mobile telephone network to the audio codec 10 through the companion chip 12 and the CPI 11, and the audio codec ( In 10), the voice data is converted into an audio signal and then output as sound through a speaker (SPK) or the like built in the personal information terminal.
    [13] Accordingly, the user can use the phone function in the mobile telephone network simply by using the above communication module as an expansion pack in the personal information terminal.
    [14] However, in the CPI 11 of the general personal information terminal, as described above, since a bus line for transmitting and receiving audio data and voice data is allocated and used, a system performance (System performance) is deteriorated. Will occur.
    [15] In addition, when the communication module is used in a personal information terminal as described above, since the overall bulkiness becomes large, it is inconvenient to carry and there is a problem in that the cost increases because an expansion pack must be purchased separately.
    [16] Therefore, the present invention was created to solve the above problems, and built-in a communication module for connection connection with a mobile telephone network in a personal information terminal such as a PDA (PDA), minimizing the degradation of the system performance of CPI. It is an object of the present invention to provide a personal information terminal with a built-in communication module for simplifying the device.
    [1] Figure 1 shows the overall configuration for a general personal information terminal,
    [2] 2 illustrates a configuration of a personal information terminal having a built-in communication module according to the present invention.
    [3] ※ Explanation of code for main part of drawing

    [5] 12: companion chip 13: video controller
    [6] 14: CD 15: Expansion Pack
    [7] 25: communication module
    [17] Personal information terminal with a built-in communication module according to the present invention for achieving the above object, the audio codec and the communication module is integrally included in the personal information terminal, the audio codec and the communication module is directly connected and connected It is characterized by directly transmitting and receiving call signal data received and signal processed through a microphone, and sign data received and signal processed through a mobile telephone network.
    [18] Hereinafter, a preferred embodiment of a personal information terminal having a built-in communication module according to the present invention will be described in detail with reference to the accompanying drawings.
    [19] FIG. 2 shows a configuration of a personal information terminal incorporating a communication module according to the present invention. In a personal information terminal such as a PDA, an audio codec 10, a CPI 11, and a companion chip 12 are illustrated. ), A video controller 13, an LCD 14, and the like, and a communication module 25 is integrally included in a personal information terminal.
    [20] As described above, the communication module 25 is wirelessly connected and connected to a mobile telephone network such as a CDA or a GSM by an antenna ANT. It will perform the function.
    [21] The audio codec 10 converts a user's voice signal received through a microphone (MIC) embedded in a personal information terminal into audio data and outputs the audio signal directly to the communication module 25.
    [22] In addition, the communication module 25 converts audio data output from the audio codec into voice data suitable for a mobile telephone network, and then performs a series of operations of wireless transmission to the mobile telephone network through the antenna.
    [23] The communication module 25 directly outputs the voice data received through the mobile telephone network to the audio codec 10. The audio codec 10 outputs the voice data output from the communication module. By converting the signal into a signal and processing the signal, a speaker (SPK) built in a personal information terminal may be output as a sound sound or an earphone jack (not shown).
    [24] On the other hand, the communication module 25 is operation controlled by the companion chip 12, the audio codec 10 is operation controlled by the CPI 11, in the companion chip 12, When a call with a mobile telephone network is established through the communication module, the fact is transmitted to the CPI 11, and the CPI 11 is connected to the audio codec 10 so that the above handset operation is performed. Perform the interface operation.
    [25] Therefore, the CPI 11 of the personal information terminal does not need to allocate a separate bus line for transmitting and receiving audio data and voice data, thereby minimizing the CPI system performance degradation due to the bus line allocation and use. I can do it.
    [26] Or more, preferred embodiments of the present invention described above, for the purpose of illustration, those skilled in the art, within the technical spirit and the technical scope of the present invention disclosed in the appended claims below, to further improve various other embodiments Changes, substitutions or additions will be possible.
    [27] A personal information terminal having a communication module according to the present invention constructed and operated as described above includes a communication module (RF Module) for connection connection with a mobile telephone network in a personal information terminal such as a PDA. By directly transmitting and receiving audio and voice data through an interface with an audio codec, it is possible to minimize the degradation of the CIF performance of a personal digital assistant, and to increase the volume and cost of using a separate expansion pack connection. It is a very useful invention that can prevent the occurrence of the source.
