The invention relates to a method for the improved exploitation of resources between telecommunications networks and IP networks (for example, corporate LANs or the public Internet), for reducing the costs of permanent connections (always-on connections) and for optimsing IP address economy. According to said method an access, authentication and multiplex device ("RAMSES-client") replaces the usual RADIUS client. Said RC has an authentication device (RAC) which is connected to the ISP-specific authentication device and authenticates the ISP access of the subscriber. During the periods when there is no traffic, the RC deactivates the connection between the telecommunications network and the IP network, while the subscriber-side connection is maintained. When the subscriber has new data traffic, the RC automatically activates the IP connection concerned to the ISP with reversion to the stored authentication data. This makes a static use of the limited resources between the telecommunications and IP networks, such as dynamic IP addresses, PVCs, transmission channels, lines etc, possible. Additional RAMSES protocol elements allow the ISP-side activation of the partial connection for ISP-initiated e-mail delivery.
