From an abstract perspective, the invention relates to 2 components. One component is arranged on a mobile terminal, information corresponding to the GPRS standard being embedded in IP packets in order to be transmitted to the second inventive component via an IP tunnel. The second component represents an IP serving GPRS support node (IP-SGSN) in the IP network, which receives the packets from the tunnel and unpacks the packets so as to subsequently send them on to another GSN, for example. The additional GSN is responsible for other mobile terminals or makes it possible to establish a connection to the internet (GGSN). The second component consequently has the form of a conventional SGSN towards the outside for additional GSN while being considered as the end of a tunnel in the direction of the mobile terminal.
