Patent ID: 7620015

Claim:
A method for seamless handover of mobile devices in heterogeneous networks in which method a mobile device or the mobile network to which it belongs is moved between different topological locations and transmits and/or receives data by means of one or more network access technologies without the data transfer between at least one OSI Layer 7 Client IP application, running on the mobile device, and at least one OSI Layer 7 Server IP application, running on an Internet server, being interrupted, the method comprising the steps of: requesting, by the at least one Client IP application, the sending of one or more first data units to an OSI Layer 7 client-service module, the one or more first data units containing a client payload and a first set of headers and/or footers for each OSI Layer traversed to reach the client-service module; creating, by the client-service module, one or more second data units and sending it or them to at least one OSI Layer 7 server-service module, the one or more second data units containing the client payload of the first data units and a second set of headers and/or footers for each OSI Layer traversed to reach the at least one server-service module; and creating, by the at least one server-service module, one or more third data units and sending it or them to the at least one Server IP application, the one or more third data units containing only the client payload and a third set of headers and/or footers for each OSI Layer traversed to reach the at least one Server IP application.
