A method for authenticating a user for the purpose of establishing a connection from a mobile terminal to a WLAN network

摘要

A user in a telecommunication network wants to use a WLAN access. For this he needs a WLAN authentication token, a login and a password. The crux of the invention is that for the transmission and communication of the authentication data to the WLAN not the SMS protocol is used, but the alternative USSD protocol (Unstructured Supplementary Service Data). DOLLAR A These so-called USSD strings can be easily entered via the keyboard of the terminal by the user. The USSD string is not sent to the SMS gateway as in the already known method, but directly to the user register (HLR) of the mobile network.
