METHOD FOR VERSION MANAGEMENT AND UPDATE OF PUBLIC WIRELESS LAN SERVICE ACCESS PROGRAM BY USING EAP-TLV MESSAGE

摘要

The invention EAP-TLV message to versioning and updating method of using a public wireless LAN service access program relates. Commonly, the air used for the WLAN service, and service authentication, or equipped with a built-in wireless LAN card terminal, the WLAN access point (AP), EAP-MD5 authentication system providing authentication (AAA server), DHCP server, and The connection management server, the program is necessary. In the present invention, in the version management and to update the program of the connection method of the terminal for receiving the public wireless LAN service authentication in association with the above system, the terminal ID to the public wireless LAN service to the authentication system via an access point (AP) Steps to perform EAP-MD5 authentication, depending on / Passwd; EAP-MD5 in the authentication process, device and receive EAP-TLV / Version Request message with EAP-TLV / Version Response messages between authentication systems via AP steps to check the version of the public wireless LAN service access program; And then check the version, and if the authentication is confirmed by the AP from the authentication system comprises transmitting the EAP-Success message indicating an authentication success to the device. Therefore, when applying the method of the present invention, DHCP IP address assignment at the same time as the Internet, by transmitting and receiving the EAP-TLV messages for checking the version of the program in connection with EAP-MD5 authentication procedure using a public wireless LAN connecting service program in the terminal connection is available, so it is possible to shorten a user waiting time.
