Description

  The present invention relates to a computer apparatus and a computer program used in a network such as a LAN.

  In recent years, construction of network systems using LANs has become common.

Normally, IP addresses and other settings are required to connect a terminal device to a LAN. However, this setting requires specialized knowledge and is difficult for the user to set easily. There are many. For this reason, the IP protocol has a function called DHCP (Dynamic Host Configuration Protocol), which can take a method of setting an IP address and performing collective management simply by connecting a terminal device to a network. This DHCP includes a mode in which the terminal device is automatically and permanently assigned like BOOTP, and a mode in which an IP address is assigned only for a limited period or until the terminal device is released. For example, when a private network is configured by a plurality of terminal devices and a router device, the terminal device is connected to the router device by configuring the router device as a DHCP server and the plurality of terminal devices as DHCP clients. By transmitting a DHCP discovery packet from the router, the IP address, subnet mask, DNS server address, and the like can be set from the router device. (For example, refer to Patent Document 1).

  FIG. 7 is a diagram showing an operation sequence of the computer apparatus according to Embodiment 1 of the present invention. The operation of the computer device 20 will be briefly described with reference to FIG.

The computer device 20 is connected to the wired LAN interface unit 11 of the router device 10 via a wired LAN interface unit 21 by a wired cable. In this state, the computer device 20 broadcasts a wireless parameter information request as a UDP packet via the wired LAN interface unit 21 (S1). Upon receiving the broadcast wireless parameter information request, the router device 10 broadcasts the wireless setting parameter information stored in the storage unit as a UDP packet (see FIG. 6) via the wired LAN interface unit 11 (S2). . When the computer device 20 receives the broadcast wireless setting parameter information, the computer device 20 sets the wireless parameter of the wireless unit (wireless LAN card 24 or wireless unit 28) of the computer device 20 based on the received wireless parameter information. Then, as a response, the wireless setting parameter information set in the wireless unit is transmitted to the router device 10 (S3).

  After the wireless parameters of the wireless unit of the computer device 20 are set in this manner, when the wired cable of the wired LAN interface unit 21 of the computer device 20 is removed, the computer device 20 communicates wirelessly with the router device 10 and the wireless unit. Connect with. For example, when the computer device 20 accesses the web server 50, the access request is sent to the wireless means 13 of the router device 10 via the wireless unit of the computer device 20, and further via the WAN I / F 12 of the router device 10. To the web server 50 (S4). When the web server receives the access request, the web server transmits the web page of the portal site to the computer device 20, and the web page is sent to the wireless unit of the computer device 20 via the wireless means 13 of the router device 10. A web page is displayed on the display unit 23 by the operation of the control means 27 of the apparatus 20 (S5).

  Hereinafter, operations of the router device and the computer device according to the first embodiment of the present invention will be described with reference to the flowcharts of FIGS. 9 and 10. It is assumed that the router device and the computer device are in a state where the wired LAN interface unit 11 of the router device 10 and the wired LAN interface unit 21 of the computer device are connected by a wired LAN cable as shown in FIG.

  FIG. 9 is a diagram showing an operation flowchart of the router device according to the first embodiment of the present invention, and FIG. 10 is a diagram showing an operation flowchart of the computer device according to the first embodiment of the present invention.

  First, the parameter setting operation of the router device will be described with reference to the flowchart of FIG.

  When starting the operation, the control means 16 of the router device 10 determines whether or not a setting information transmission request is broadcasted via the wired LAN interface unit 11 (S11). If it is determined that the setting information transmission request has been broadcast, the control means 16 determines whether the setting information transmission request is a request for only wireless setting parameter information or a request for network setting information in addition to the wireless setting parameter information. Determine whether. As a result of the determination, if it is determined that the request is only for the wireless setting parameter information, information relating to the part (a) in the data part of FIG. 5 is taken out from the storage means 14 and used as setting information for transmission. On the other hand, if it is determined that the request is for the network setting information in addition to the wireless setting parameter information, it is determined from the network setting information table of FIG. The information is taken out from the storage means 14 and is used as setting information for transmission (parts (a) and (b) of FIG. 5). The IP address is generated by the control unit 16 referring to the network setting information table in FIG. 6 for an assignable IP address that is not used by another terminal device. Further, after assigning the IP address, the IP address and the MAC address of the assigned terminal device are associated and stored in the network setting information table of FIG.

Thereafter, the control means 16 transmits the setting information for transmission from the wired LAN interface unit 11 by unicast transmission or broadcast transmission to the network by the UDP protocol (S12). Thereafter, when the control means 16 determines that the response to the transmission in S12 has been unicast transmission or broadcast transmission to the router device 10 (S13), the setting information transmitted in S12 and the setting information transmitted in S13 are the same. If it is determined that they do not match, error processing is performed to notify the display means that there is an error (S15). On the other hand, if it is determined that they match, the fact that the automatic setting has succeeded is displayed on the display means 15 (S16), and the automatic setting ends.

  As the operation of the router device 10, only the operations of S11 and S12 may be performed and the operations of S13 to S16 may not be performed. In this way, the processing load on the router device 10 can be reduced. It becomes.

  Next, the wireless parameter setting operation of the computer apparatus will be described based on the flowchart of FIG.

  The input unit 26 of the computer device 20 is operated to specify activation of the wireless setting program 25 c stored in the storage unit 25. When this designation is made, the control means 27 starts the operation according to the wireless setting program 25c and causes the display unit 23 to display a screen for setting wireless parameters. On the screen for wireless parameter setting, at least two automatic setting start buttons by GUI (wireless parameter automatic setting button and wireless and network parameter automatic setting start button) are displayed. The control means 27 determines whether or not the automatic setting start button is pressed (S20). If it is determined that the automatic setting start button has not been pressed, the control means 27 next determines whether setting information is stored in the second setting storage unit 25b (S21). If it is determined that the setting information is stored in the second storage unit, it is determined whether the wireless setting parameter information stored in the second setting storage unit 25b has already been written in the wireless unit (S22). If the information setting unit 27d determines that the wireless setting parameter information stored in the second setting storage unit 25b has already been written in the wireless unit, the process proceeds to S20. On the other hand, when determining that the setting information is not stored in the second setting storage unit 25b, the information setting unit 27d proceeds to the operation of S20.

  If it is determined in S20 that the automatic setting start button has been pressed, the control unit 27 detects whether or not a local network is connected to the wired LAN interface unit 21 (S23). This detection is performed at the physical layer level, but may be performed at the physical layer level or higher.

  Next, when the control unit 27 determines that a local network is connected to the wired LAN interface unit 21, the setting information request unit 27a sends a request for transmitting parameter setting information for communication with the router device 10 to the data unit. The UDP / IP packet included in is broadcasted via the wired LAN interface unit 21 (S24). Here, the control means 27 changes parameter information for requesting transmission in accordance with the type of the automatic setting start button that has been pressed. That is, when the wireless parameter automatic setting button is pressed, only the transmission related to the wireless parameter is requested, while when the wireless parameter and wired parameter automatic setting start button is pressed, the wireless setting parameter information is transmitted. In addition, it requests transmission of network setting information such as IP address, subnet mask, DNS address and default gateway.

Thereafter, the setting information receiving unit 27b waits for a certain period of time for the setting information to be broadcast from the router device 10 to the wired LAN interface unit 21 via the local network (S25 to 27). When the setting information sent from the router device 10 is received by the wired LAN interface unit 21 during a certain period, the wireless unit determination unit 27c determines whether or not the wireless unit (wireless LAN hardware unit) exists (S28). ). For example, when the wireless LAN card 24 is connected to the I / F unit 22, it is determined that the wireless unit is present. If it is determined that the wireless unit is present or if it is determined in S22 that the setting information has not been written in the wireless unit, the wireless unit determination unit 27c determines whether the wireless unit is a predetermined one. (S29). Here, whether or not the wireless unit is a predetermined wireless unit is determined based on the manufacturer and the product identification code stored in the storage unit 24d of the wireless LAN card 24.

  If it is determined that the wireless unit is a predetermined one, the information setting unit 27d operates the wireless LAN card driver program 25c stored in the storage unit 25, and receives the setting information received in S24 via the driver program. The wireless LAN card 24 is requested to set, and the control means 24e that has received the request via the wireless LAN card interface unit 24a stores the notified setting information in the storage unit 24d (S30). On the other hand, when it is determined that the wireless unit is not the predetermined wireless unit, the information setting unit 27d determines the wireless communication method of the wireless unit, and selects the wireless communication method of the wireless unit from the setting information received in S24. Only the appropriate setting information is selected, and the setting information is stored in the first setting storage unit 25a. When the setting information is stored in the first setting storage unit 25a, the information setting unit 27d delivers the setting information to the wireless unit driver program based on the OS program, and the information setting unit based on the driver program. 27d sets the setting information in the wireless unit (S31).

  On the other hand, when the wireless unit determination unit 27c determines that the wireless unit does not exist in S25, the information setting unit 27d determines whether the setting information is stored in the second setting storage unit 25b (S32). And when it determines with the setting information not being memorize | stored in the 2nd setting memory | storage part 25b, the setting information received by S24 is memorize | stored in a 2nd setting memory | storage part (S33).

  If it is determined in S22 that the setting information has not been written to the wireless unit, a setting button indicating whether to write to the wireless unit is displayed on the display unit 23, and the setting button is pressed from the input unit 26. The operation from S28 may be started only when there is.

  As described above, the computer program and the computer apparatus according to the first embodiment of the present invention transmit setting information for setting parameters related to radio and network to a wireless access point such as a router apparatus, and transmit the setting information from the wireless access point. After the setting information is received, it is determined whether or not the wireless unit is present in the computer. If it is determined that the wireless unit is present, the setting information received by the setting information receiving unit is set in the wireless unit. Can be easily set parameters for wireless communication.

  Further, when the wireless unit is not present, the received setting information is stored in the first storage unit. Therefore, even if the wireless unit is not present, the received setting information is stored in the storage unit. When the wireless unit is connected to the computer, it is not necessary to request the setting information again.

  In addition, after the setting information is stored in the first storage unit, if the wireless unit is added, the setting information can be retrieved from the first storage unit and set in the wireless unit, so that the wireless unit is connected to the computer. In this case, there is an effect that it is not necessary to perform a request for setting information and a process for receiving it again.

  Even if a wireless unit is present, if the wireless unit does not support the wireless method included in the received setting information, the wireless parameter is not set, and thus malfunction of the wireless unit is prevented. It has the effect that it can be.

  In addition, since the setting information is requested and received via the wired LAN interface, problems such as wiretapping of wireless parameters can be prevented.

In addition, since the setting information can include network setting information, network setting can be easily performed.

  Further, based on the information of the input means, only the necessary setting information of the wireless setting information or the setting information including the network setting information can be requested from the wireless access point, and the processing is facilitated.

  The target of the setting information can be applied not only to wireless communication but also to power line communication that requires similar setting parameters. The same effect can be obtained in a computer in which a power line communication device is connected to a PC card slot, USB port, PCI slot or the like instead of a wireless communication device.

  The present invention relates to a computer device used in a network such as a LAN and a program thereof, and can be applied to a computer device that requires setting of a wireless unit.
