Method and system for supporting service continuity for mobile communication over different access networks

process for switching between at least two different access network technologies at a mobile terminal (1) during a packet-oriented data connection to a destination address of a destination network (6) without interrupting an active network application or a Service, which furnished by means of a in the terminal (1) access control application (3) the location of the terminal available Access networks (4; 5) to the destination network (6) are determined and the compound under consideration of predetermined criteria through the respective available Access network (4; 5) and an access control application (8) the target network to the desired Destination address is routed and vice versa, wherein the access control applications (3; 8) the availability the access networks (4; 5) continuously monitor, characterized in that the access control applications (3; 8) with each other constantly information about the availability existing access networks (4; 5) exchange and automatically and without interrupting an active network application (2) or a service as needed between the available access networks (4; 5) switch, wherein the access control applications (3; 8) with each other constantly about their in force in the respective access networks ...
