Patent ID: 7206318

Claim:
A method for the user-initiated connection of a user communication terminal to an IP network via a connecting communications network with an access, authentication and multiplex apparatus located in the communications network or in a Remote Access Server access node (RAS) with an authentication unit, which is connected to the ISP-specific authentication system established in the IP network, said method comprising: the access, authentication and multiplex apparatus deactivating the connection between the communications network and the IP network in the absence of traffic and storing the user-specific and session-specific connection data SAD while the connection between the user communication terminal and the communications network remains open; automatically re-activating the IP connection in question on the basis of the stored user-specific and session-specific authentication data when the user sends renewed data traffic; and overwriting the SAD during each user-initiated session and thus storing it again, where the access, authentication and multiplex apparatus automatically relies on modified ISP authentication data.
