If the request message has been received, the destination of the request message It is confirmed whether (URL) is the public telephone 1 (step S12). When the destination is the public telephone 1, the request message is analyzed to check whether or not the ID is included (step S13). When the ID is included, the ID is extracted from the request message, and it is confirmed whether or not it matches the ID stored in the authentication data storage unit 115 (step S14).

  If the IDs match, the source MAC (Media Access Control) address included in this request message is taken out and stored in the MAC address storage area of the authentication data storage unit 115 as a pair with the matched ID (step S15). Next, the charging processing unit is instructed to start a timer that counts the available time (step S16), and the process ends. On the other hand, when the destination (URL) of the request message is not the public telephone 1 in step S12, the request message is transferred to the terminal determination unit 113 (step S17), and the process ends. If the request message does not include an ID in step S13 and if the IDs do not match in step S14, the process ends.

  Next, the operation of the terminal determination unit 113 will be described with reference to FIG. FIG. 6 is a flowchart showing the operation of the terminal determination unit 113.

If the request message has been transferred, the terminal determination unit 113 stores the request message in the request message storage unit 117 (step S22). . Next, it is confirmed whether or not the source MAC address of the request message matches the data stored in the MAC address storage area of the authentication data storage unit 115 (step S23). If they match, a processing request is transmitted to the gate processing unit 114 (step S24), and the processing ends. If they do not match, a processing request is transmitted to the ID input screen distribution unit 115 (step S25), and the processing ends.

  Next, the operation of the gate processing unit 114 will be described with reference to FIG. FIG. 7 is a flowchart showing the operation of the gate processing unit 114. The gate processing unit 114 confirms with the billing processing unit 15 whether the available time has been exceeded (step S31). If the available time has not been exceeded, it is confirmed whether or not a processing request has been received from the terminal determination unit 113 (step S32). If a processing request has been received, it is stored in the request message storage unit 117. The requested message is transferred to the line interface 17 (step S33). When not received, the processing from step S34 is performed.

  Next, it is confirmed whether or not the content downloaded from the Internet 5 has been received by the line interface 17 (step S34). If it has not been received, the processing is terminated. If the content has been received, the content is transferred from the line interface 17 to the wireless LAN unit 20 (step S35), and the process ends after the transfer is completed. On the other hand, when the available time is exceeded in step S31, the ID and MAC address stored in the authentication data storage unit 115 as a pair are deleted (step S36), and the process is terminated.

  Next, the operation of the ID input screen distribution unit 115 will be described with reference to FIG. FIG. 8 is a flowchart showing the operation of the ID input screen distribution unit 115. The ID input screen distribution unit 115 checks whether or not a processing request has been received from the terminal determination unit 113 (step S41), and ends the processing when it has not been received. If a processing request has been received, an ID input screen is transmitted to the user terminal 6 via the wireless LAN unit 20 (step S42), and the processing ends. In this case, an HTML (HyperText Markup Language) file for displaying the ID input screen on the browser, which is stored in the memory in advance, is used as the ID input screen.

  According to this embodiment, an ID is issued to the user who has paid the usage fee, a request message including the issued ID is transmitted to the terminal device, and the source MAC address included in the request message is set as unique address information. Since it is stored, in subsequent request messages, it is possible to identify whether or not it is a connection request from the user only by confirming the match of the source MAC address. For this reason, even when there is a possibility of receiving a connection request from another terminal device, such as a connection using a wireless LAN, only the user who paid the usage fee without pre-registration is connected to the Internet.
