Abstract

<P>PROBLEM TO BE SOLVED: To obtain a method of performing internet data communication with the other apparatus and equipment needing data communications after connecting them via a single hardware-like circuit, using a wireless data communication network and a wired internet data communication network. <P>SOLUTION: In an interface state formed via an arbitrary internal unit needing data communication and an internal connection unit, data reception signals are sent to a processor (200), and the processor checks whether the internal unit has received the signals over a cable network or a radio network and is connected with the cable/radio network via an external connection unit to secure a route available for the data communication. When the signal utilizes the radio network, the processor detects Baudrate for ensuring the success in radio data communication with various radio modems. After detecting the Baudrate, several authentication steps that various mobile communication service carriers require are passed to communicate at a low or high speed data transmission speed the radio network supports. <P>COPYRIGHT: (C)2005,JPO&NCIPI

  For features and advantages of the present invention, please refer to the attached drawings and the following description.

  FIG. 1 is an overall system configuration diagram according to the present invention, which is roughly divided into three. That is, an internal device connection unit (300), a processing unit (200), and an external device connection unit (100).

  The mechanism for receiving data is as follows.

  When the internal device (500) sends a data reception signal to the processing unit (200) of the present invention through TX2 via the internal connection unit, the processing unit (200) receives it and the SIGNAL of the internal device (500) is wired / wireless. It senses the network and connects to the wired / wireless network (400) through the external device connection unit (100) to secure a path for data communication.

  The external device connection unit (100) receives data by connecting with an IP conforming to the international standard. The process of receiving data from the corresponding IP is connected to the external wired / wireless network (400) through the external device connection unit (100) and sent to the processing unit (200) through RX1.

  The processing unit confirms wired or wireless processing, and processes the processing method by dividing into a wired processing unit (210) / wireless processing unit (220). The RX1 data between the connector 2 (120) and the wireless processor (220) is transmitted using the most common communication method, Serial (RS-232 standard) communication, and the processor (200) is connected to the connector 3 The data is sent to the device which is going to receive the data through (310). Interfacing with devices that are trying to receive data is also done through the most universal Serial (RS-232 standard) communication.

  Data transmission is performed in the reverse order of the data reception method described above.

Next, the overall software structure will be described with reference to FIG.
This communication apparatus uses a wired system and a wireless system as an interface, and can transmit and receive data by FTP (470a), TFTP (490a), and Socket (480a) systems.

  The wired system supports a dedicated line (210a), ADSL (210a), and Cable network (210a) using the Ethernet system (310a). A DHCP client module (441a) is built in, the host IP and gateway IP can be set dynamically when the device is called, and an ARP protocol (442a) and a mapping table module are built in. Using Ethernet, the host IP and gateway IP can be set to static / dynamic (using DHCP).

  In the wireless system, a CDMA data service can be used. Connect to a mobile terminal and use it as a modem to support PPP connection (440a). The communication layer supports both TCP (450a) and UDP (460a), and can be programmed using sockets in a manner desired by the user. Built-in FTP (470a) and TFTP (490a) client modules are available.

  A software block diagram will now be described with reference to FIG.

  When data transmission is requested, the application (800c) saves the requested transmission data in the transmission buffer of the Workspace (1000c) module and transmits it with the service module (FTP, TFTP, Socket) of the Comm module (700c) depending on the form. To do.

  The process will be described in time series with reference to FIG.

  When transmission data is generated, an App module (100d) SendData (110d) message is called to request transmission. Upon receiving the Send Data message, the App module (100d) first writes the received data to the transmission buffer in the Workspace module (200d). After copying the (CopyData (210d)) data, the App module (100d) sends an OpenDataService (310d) message to the comm module (300d), requesting to open a PPP session.

The wireless data transfer request processing stage 1 (preparation stage) will be described with reference to FIG.
A request to open a PPP session is received from the App module through the OpenDataService (110e) message. The FineInterface (610e) message is sent to the UART module (600e), and the transfer device (wireless modem) confirms the current connection status.

     The wireless data transfer request processing stage 2 (transfer stage) will be described with reference to FIG.

  The App module receives a request for communication session setting with the program of the other server through a ConnectServer (110f) message. In the case of a TCP program, the Comm module (200f) requests the TCP connection of the OpenTCP (310f) message for each port to the TCP module (300f) in the case of a TCP program.

  Wired data transmission will be described in time series with reference to FIG.

  When data to be transmitted is generated, a SendData (110g) message of the App module (100g) is called to request transmission. Upon receiving the SendData (110g) message, the App module (100g) first writes the received data to the transfer buffer in the Workspace module (200g). After that, the App module (100g) sends an OpenNetwork (310g) message to the Comm module (300g) to request initialization of the network module. If there is a setting for dynamic IP generation, the Comm module sends an InitDHCP (410g) message to the DHCP module (400g).

  The wired data transfer processing stage (one stage) will be described next with reference to FIG.

  A request for network initialization is received from the App module through the OpenNetwork (110h) message. Sends an InitDHCP (610h) message to the DHCP module (400h), searches for a DHCP server, and acquires host IP, gateway IP, and subnet mask information.

  Next, the wired data transfer request processing stage 2 (transfer stage) will be described with reference to FIG.

  The App module receives a request for the program and communication session setting of the partner server through the ConnectServer (110i) message. When the partner server program is a TCP program, the Comm module (200i) requests the TCP connection to the TCP module (300i). If the connection with the partner server is successful, the APP module sends a StartSendData (120i) message to the Comm module (200i) to request transmission start. Upon receiving the transmission request, the Comm module (200i) divides the data stored in the transmission buffer of the Workspace module (100i) according to the transmission capacity (GetData (210i)) and transmits it. When a ProcessComm (310i) message is received during or after transmission, the received data is stored in the receive buffer of the Workspace module (100i) (PutData (220i)) and notified to the App module.

  As described above, by using the development method provided by the present invention, application to a wired / wireless network or various connection environments becomes possible. As a result, the development period can be shortened and the development cost can be reduced.

  Further, as a specific form, it can be used for all wired networks (dedicated line network, ADSL network, Cable network).
