BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that In the case of no conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The computer involved in the following embodiments includes not only a personal computer (PC), but also other mobile or fixed devices that can provide drivers, data card interfaces, and application software running functions. computer. In the following partial embodiments or preferred embodiments, a PC is taken as an example, but is not limited thereto. 1 is a flow chart of a method for communicating with a wireless network using a data card according to an embodiment of the present invention. As shown in FIG. 1, the process includes the following steps: Step S102: After the data card is connected thereto, the computer is locally Some drivers identify the data card and directly run the application software that interacts with the data card, wherein the data card provides communication with the wireless communication network; Step S104, the computer uses the application software to communicate with the wireless communication network via the data card, wherein The computer uses the application software to transmit information that the computer interacts with the wireless communication network between the computer and the data card through the driver. Through the above steps, the driver of the data card on the computer to which it is connected is no longer the driver unique to the data card, but the general driver provided by the computer, and the application software can be compiled to be directly run without the need Installed application software. Through such processing, the installation process is no longer needed when using the data card, and only the data card needs to be connected to the computer to run the application software. This can solve the problems in the related art due to the need to install software and drivers. In turn, the use of the data card is more convenient. In the implementation, because the computer itself can provide more types of drivers, the driver used by the data card can be selected according to the actual situation. The purpose of the driver is to provide data interaction between the computer and the data card, as long as this can be achieved. A variety of drivers can be used. Of course, considering that there are more or less differences in computers, it is easier to select a driver that is common to most computers. For example, you can use a Mass Storage (MS) driver, which can be large. Most operating systems and computers support it, and it is easier to implement the data card to support the driver. When using the MS driver, the computer can interact with the data card through the MS-driven buffer. For example, the computer can write information to the MS. In the driven buffer, the MS driver sends the information to the data card. Preferably, the application software is implemented by using a Small Computer System Interface (SCSI) instruction or a predefined instruction during execution. The program transfers information between the computer and the data card. It should be noted that as long as the instruction format acceptable to both parties is defined, it is of course possible to use other existing instructions. In implementation, the application software can be created as software that can be run directly without installation (this type of software can be called green free installation software). This type of application software can omit the installation process and thus avoid installation. Various problems that arise during the process. If the application software is made to run automatically, then the use will be more convenient. If it can't be run automatically, it only needs the user to run it manually, and it can solve the problems in the related technology, just one more operation. In addition, the application software can be saved in the data card, which is more convenient to use (of course, the application software can also be stored in other media, as long as the user can get the application software and copy it to the computer). For example, the computer enumerates a virtual optical drive device corresponding to the data card, wherein the virtual optical drive device stores the application software; the computer automatically invokes the virtual optical drive device and runs the application software. The above embodiments can enable the computer to perform any form of communication with the wireless communication network. Since the most important function provided by the wireless mobile communication network is voice service, the mobile terminal (for example, a mobile phone) has relatively large call radiation, and the battery power has a certain limit. This makes mobile terminals such as mobile phones have some restrictions on their use, so it is important to support voice services on fixed terminals (computers). The voice service is taken as an example for description. The computer uses the application software to perform a voice call service with the wireless communication network, wherein the computer transmits voice data and/or control information of the voice call service between the computer and the data card in accordance with an agreed format and through a driver. For example, the application provides an interface for receiving the called terminal information, and calls the called terminal according to the acquired called terminal information, wherein if the called terminal information is the number of the called terminal, the computer directly calls through the data card. The called terminal; if the called terminal information is the user name of the called terminal, the computer sends the user name to the data card, and the data card searches for the number corresponding to the user name and calls the called terminal. In this embodiment, a system for communicating with a wireless network using a data card is also provided. It should be noted that the system is used to implement the foregoing embodiments and preferred embodiments thereof, and has not been described herein. The following describes the system in sections. The system includes: a data card and a computer, wherein the data card is coupled to the computer and the data card provides communication with the wireless communication network. The computer includes: a driver for identifying the data card; the data card includes: storing the data card The application software, after the data card is recognized by the driver, the application software runs directly on the computer; the data card includes an interaction module, and the interaction module and the application software mutually transmit information of the interaction between the computer and the wireless communication network through the driver, thereby realizing the computer and Communication over a wireless communication network. Preferably, the above driver is a mass storage device MS driver; application software is used to write information into the buffer driven by the MS, and the MS driver sends the information to the data card. Preferably, the interaction module and application software transfer information between the computer and the data card through the driver using a small computer system specific interface SCSI command or a predefined command. Preferably, the application software is stored in the computer to enumerate a virtual optical drive device corresponding to the data card, wherein the computer automatically invokes the virtual optical drive device and runs the application software. In this embodiment, a data card is further provided for communicating with the wireless communication network, including: a storage module, configured to store application software, where the application software directly runs after the data card is recognized by the local driver of the computer; On the computer; the interaction module, the interaction module is used for transmitting information with the application software through the driver, and realizing communication between the computer and the wireless communication network, wherein the information is information that the computer interacts with the wireless communication network. It should be noted that the above data card can be connected to the computer through the USB, and of course, it can also be connected through other connection methods. Through the above embodiments, the installation operation of the driver and the application program is bypassed, so that the data card does not need to consider various computer environments; and the switching of the optical disc to the serial port device is not required, saving time and giving the user a good experience; Furthermore, it satisfies the requirement that the user wants to use the voice service directly by means of the fixed terminal, and improves the traditional data card voice service, thereby eliminating the defects in the use method of the above data card, so that the data card is inserted and dialed. Easy to use. The following embodiments are described as an example of providing voice services on a driverless basis. Since voice services are provided, it is convenient for a user to make a call using a fixed terminal anytime and anywhere. 2 is a schematic diagram of a computer communicating with a wireless communication network in accordance with a preferred embodiment of the present invention, the figure including: a PC, a USB data card, a wireless access point (eg, a base station), and a mobile terminal.

A green free installation software runs on the PC, which mainly includes two modules: control signaling and voice stream processing module, SCSI command\USB custom request parsing module. The SCSI command \USB custom request parsing module is responsible for communicating with the MS driver on the PC, reading SCSI from the drive buffer. The data packet returned by the instruction and the custom USB request is decapsulated in the SCSI command data and the custom request data packet storing the voice stream and the control information, and sent to the above control signaling and voice stream processing module. At the same time, it is responsible for writing the compressed code stream and control information that has been compression-encoded by the control signaling and voice stream processing module into the MS driver buffer, and the MS driver sends the data stream to the data card side through the SCSI command and the custom request. The control signaling and voice stream processing module is responsible for communicating with the sound card driver of the PC, decompressing and compressing the sound data, and playing and recording the sound. For the USB data card, there are five modules, namely: MS function driver, parsing module, AT command processing module, voice function module, signaling processing module (the five modules realize the connection support with the computer and the function of the interaction module) , also realizes some functions of communication with the wireless communication network) „ MS function driver module is mainly responsible for the processing of SCSI commands and custom requests sent by the host, running on the USB protocol stack; the parsing module is responsible for sending the green free installation software. The decoupling of the call control information and the voice code stream, and the encapsulation of the control signal and the voice code stream returned by the AT command processing module and the voice function module; the AT command processing module is responsible for parsing the AT command and forwarding the call control information to the peer end, And returning the call processing result of the opposite end to the AT command processing module and returning to the PC side; the voice function module is responsible for sending and receiving the PCM voice code stream; the signaling processing module is responsible for processing the call control information. The related technology is avoided by the above embodiment. User software and drivers must be installed to use voice The disadvantages of the service greatly save the user's time waste due to the cumbersome installation steps, the problem that the voice service cannot be used normally due to the difference of the computer software environment, etc. In addition, a mode switching operation is also reduced, which is reduced to some extent. The probability of occurrence of the error shortens the time for the user to wait for the voice service. In addition, the voice data is a burst of data service, and the amount of data on the USB bus after the optical disk device is normally read is small, and the bandwidth cannot be utilized well. The voice service on the optical disc device just makes up for the lack of bandwidth utilization. The preferred implementation process of this embodiment will be described below with reference to Fig. 2. First, the USB data card is set as a virtual optical disc device, thus acting as a slave device. The data card is recognized by the PC host as a mass storage device. This aspect is due to the fact that the Windows operating system or the mainstream operating systems such as MAC and Linux integrate the large-capacity storage device driver into the operating system, eliminating the installation process of the USB device driver. On the other hand, a virtual disc device can store The green software running on the PC can be used to transfer the green software executable program to the computer through the autorun.inf file in the CD when the USB device is connected to the computer. The green software does not need to be installed and runs directly. It can be used on a PC. It is used to control PC language. Sound compression, decompression, playback, and transmission; and data interaction with the mass storage device on the host side and the CDROM driver is required. On the one hand, it is responsible for parsing the voice call control signals and voice streams in the SCSI commands and USB custom requests sent from the MS driver, and packaging the voice call control signals and voice streams into SCSI commands and custom requests for transmission to the data card. , but also responsible for communication with the PC's sound card driver, playing and recording sound. This application is used as the input interface of the called phone number. You can enter the phone number or the name in the address book to make a voice call.

The communication between the PC and the data card is via the USB protocol based on the USB bus and the SCSI protocol. This is to meet various operating systems of Windows and Linux and MAC. The main work done on the USB data card side is to implement the MS function driver to interface with the voice function module and the AT command processing module, so as to ensure that the voice call control signal and the PCM code stream are sent to the PC through the mass storage device. Voice call control signals and PCM streams are sent to the PC via USB custom requests and SCSI commands. The IN (relative to the host) data phase can be sent to the USB bus as a USB custom request and SCSI command. And the data sent from the host to the USB device through the USB custom request and the OUT (relative to the host) data phase of the SCSI command is received from the USB bus. The implementation of voice services includes two aspects, one is the establishment and release of connections, and the other is the processing of voice streams. It is divided into a signaling processing part and a data processing part. 3 is a flow chart of a voice service according to an embodiment of the present invention. As shown in FIG. 3, the upper part is a connection establishment process, the middle part is a data processing part, and the lower part is a connection release process. The following describes the active call and hang up process of the USB data card. The main purpose is to use the SCSI command to complete the voice call function under Windows. The use of the USB custom request is similar to the use protocol, and the implementation method is similar. The request mode is briefly described. The process includes the following steps: Step S301: The application receives the telephone number input of the user interface, and transmits the dialing instruction ATD to the data card side through the OUT data phase of the SCSI command, that is, the MODEM side or the board On the side, the parsing module on the board parses the AT command and sends it to the signaling processing module. The signaling processing module sends the call signaling to the mobile network. This is the call origination process. Step S302, the peer receives the call request, rings and selects the answer, and sends a confirmation message that the signaling is connected to the network, and the information is encapsulated into the IN data phase of the SCSI command and transmitted to the PC side application after being processed by the board side. Program, the application changes state to the connected state. Step S303, the application decapsulates the voice stream from the SCSI and plays it. Step S304, the step is a process of how the voice code stream of the calling party is transmitted to the peer end. First, the PC side green software application records the user voice, and performs compression, and transmits the OUT data phase of the SCSI command to the board side via the USB bus. The board side parses the SCSI command OUT data phase, extracts the voice data and sends it to the voice function module, and the voice function module samples, quantizes and encodes the voice data, and converts the voice data into a PCM code stream and transmits it to the peer user. Step S303 is the reverse process of step S304, which is a process in which the voice signal of the opposite end is processed on the board side and the PC application, and is mainly a process of SCSI instruction encapsulation and decapsulation. Step S305 and step S306 are signaling processing procedures in which the calling party hangs up the call, and the calling party first sends an AT+CHUP command to the board through the data phase of the SCSI command, and the board side processes and forwards it to the peer end, and An OK command is issued to the PC application to inform the call that the call ends normally. Of course, this embodiment also supports the process of initiating a call by the opposite end and the active end of the call by the opposite end. The process is similar to the above, and is not mentioned here. For MAC and Linux systems, the mass storage device 0 port is used (each USB device has this 0 endpoint USB custom request to implement the voice call function based on the drive-free. Voice call control information and voice code stream are passed The data phase of the USB custom request interacts on the PC side and the board side. The protocol used by the SCSI command is different, but the process is the same, that is, the data is encapsulated and decapsulated into a USB custom request for transmission. 4 is a working flow diagram of a board side according to an embodiment of the present invention. As shown in FIG. 4, first, a data card is connected to a PC, and a large-capacity storage device driver and a CD-ROM drive are automatically loaded to perform a board-side task. After the initial ^^ initial ^ !t is completed, the MS function driver and USB request module on the board side will wait for the arrival of a specific command. If the data card is not online at this time, it will end directly, otherwise the MS function driver and the USB request module will input. The data and the output data are parsed, and the call control information is stripped out. The parsing module on the board side judges the call control information, if the name is not a phone number method Then, the SIM card address book is searched, and then found to the wireless processing module for signaling establishment process. After the signaling is sent to the peer end, the peer end hangs up and the call ends, otherwise the call connection establishment confirmation information is transmitted back to the board side. The MS function driver and the USB request module on the board side send the confirmation information as the data phase to the PC side. After that, the MS function driver and the USB request module encapsulate and decapsulate the voice code stream, and transmit it to the PC side and to the board side. The process of the voice function module until the board side receives the call end message. FIG. 5 is a flowchart of the host side green software application according to an embodiment of the present invention, as shown in the figure. As shown in Figure 5, the application can receive two inputs, the control information is the voice call information and the voice code stream. The control information is directly transmitted to the board side by the SCSI command or the package of the USB custom request. The application reads the voice stream from the sound card driver, compresses it, encapsulates it into the OUT data phase of the SCSI command or USB custom request, and sends it to the board side via the mass storage device driver. The application also detects if the USB port has data. If the incoming control information, the application directly decapsulates the received data and changes the state. If the voice stream is received, the packet is decapsulated and sent to the audio. The device plays. Figure 6 is a schematic illustration of a preferred plate side and PC side in accordance with an embodiment of the present invention, and a preferred embodiment will be described in detail below with reference to Figure 6 . The PC side application mainly consists of a SCSI command \USB custom request parsing module, control signaling, and a voice stream processing module. The SCSI command\USB custom request parsing module is responsible for encapsulating the voice call control signal and voice code stream through the SCSI command\USB custom request, and after the connection reply information of the mobile terminal and the voice code stream are released from the SCSI\USB custom request package. Return to the UI interface and the sound card. The control signaling and voice stream processing module is responsible for sampling, compressing and encoding the data transmitted from the audio device, and transmitting it to the SCSI command \USB custom request parsing module for packaging; and is also responsible for customizing from the SCSI command \USB The voice code stream parsed by the request parsing module is decompressed, decoded, and transmitted to the audio device for playback. In summary, the functions of the PC-side application include: On the one hand, listening to the buffer of the mass storage device driver, whether the voice stream data arrives, and if so, playing it after decapsulation from the SCSI command or the custom request; On the one hand, the voice information of the sound card device is compressed and encoded by the code stream, and then encapsulated into the data field in the SCSI command and the USB custom request, and sent to the data card device through the USB bus. The processing of the voice call signal is not a voice processing module on the board side, but a signaling processing module. After the analytic module is de-SCSI encapsulated, the voice call control signal is directly sent to the AT command processing module for parsing through the OUT pipeline (for the USB custom request is transmitted through the 0 pipe), and then parsed and then sent to the signaling processing module for signaling processing. The mobile core network (i.e., the wireless communication network) is then notified to the called terminal. Once the called terminal answers, an acknowledgment signal is sent back to the data card side. At this time, the IN pipeline (or 0 pipeline) of the signaling processing module passes the signaling to the AT command processing module to convert the format to the parsing module for processing, and the parsing module encapsulates the signaling into a SCSI command\USB custom request, which is sent through the USB bus. To the PC side, the PC-side application re-encapsulates the SCSI command\USB custom request and extracts the acknowledgment signaling. At this point, the signaling layer has been opened and the voice service can proceed. The module for processing the voice stream on the board side has a parsing module and a voice function module. The parsing module is responsible for decapsulating the voice stream and then sending it to the voice module, and then sending it to the called terminal through the CS domain. Still negative The voice stream received by the CS domain is sent to the IN pipe (or 0 pipe) of the parsing module through the IN pipe (or 0 pipe) of the voice function module, and is encapsulated and sent to the PC side application for processing. In some cases, the user does not remember to memorize the individual phone numbers. In order to solve this problem, the embodiment also supports the function of directly inputting a name to implement a voice call. When the user inputs not the phone number, the parsing module located on the board side will go through the address book on the SIM card. If a matching entry is found, the call is established. Otherwise, the error message is sent back to the UI through the SCSI command\USB custom request. Prompt call error. This function is more user-friendly in this embodiment and meets the actual needs of the user. In summary, the above embodiment utilizes the feature that the first enumerated optical disc device does not need to be installed with a driver, and realizes transmission of voice control signals and voice stream information in a large-capacity storage device channel by means of a large-capacity storage device, and discards the voice service. The fact that traditional third-party drivers must be applied can lead the data card to a new working model. In the above embodiment, the working mode of the original data card is not discarded. In addition to the direct use of the telephone call service, the user can also select the normal working mode, and the normal working mode can simultaneously provide data services, voice services, short message services, and the like.
