ID mapping mechanism for controlling wireless LAN access with public authentication server

摘要

A method for improving the security of a mobile terminal in a first communications network environment by redirecting the browser request, embedding a session identification inside an HTTP request and matching two HTTP sessions using such a session identification in the authentication server. The access point processes the web request from the mobile terminal such that a session identification becomes embedded in the universal resource locator. Additionally a mapping between this session identification and the media access control address or the internet protocol address of the mobile terminal is maintained in the WLAN. When the authentication server notifies the access point about the authentication result, the session identification is used to uniquely identify the mobile terminal. All these operations are transparent to the mobile terminal.
