The volume of the mobile data traffic countinouously increases and creates new challenges for network operators. Lots of offloading mechanisms have been created and being developed. In parallel the view of „All IP” enables transparent network changes among different access technics. During traffic offloads not only mobile nodes can be performed, every IP flow may be handled by separated policies. IP address preservation arriving to a new network is an additional requirement for those applications where service continuity is a must (VPN, Videoconference). However, there are several types of use case, where the constant IP address is irrelevant (web).
In my thesis I present the current state of IP based mobility protocols started with Mobile IPv6 and Proxy Mobile IPv6. Than, I move on introducing Flow Bindings, which ensures the flow-based mobility concepts. Distributed mobility management is also described and On-demand mobility management comes up.
The above mentioned protocols may be the corner stone of IP-based mobility in 4G/LTE systems with the help of Proxy Mobile IPv6. The next step is an architecture proposal for dynamic, operator-centric, flow-based mobility handling. For executing functional and performance tests, a virtual test bed has been created.
