Abstract
The invention relates to a method for transmitting data in a WLAN network (WLAN=Wireless Local Area Network) during which WLAN messages are transmitted in the L2 protocol layer between a terminal and an access node of the WLAN network, whereby the access node can be connected to one or more data networks. According to the invention, the WLAN messages contain SIP messages with SIP authentication data (SIP=Session Initiation Protocol). The SIP authentication data is extracted from WLAN messages arriving in the access node and are integrated in the form of authentication data in messages of the RADIUS protocol and/or of the diameter protocol (RADIUS=Remote Authentication Dial In User Service).
