Mobility architecture for next generation networks

Ferreira Da Costa, Rui Pedro

Permanent access to mobile internet has become a feature of our daily lives. Be that through smartphones, tablets, or dongles, mobile users benefit from vast amounts of multimedia content at their fingertips.

Meanwhile, new access technologies like LTE have been deployed and keep their promises in terms of bandwidth and latency. Not only do they open the doors to a great variety of new usages and possibilities, but they also face new problems that were reserved to the fixed world until now.

To maintain the level of mobile user experience provided by the previous networks generation, new ways to deliver this huge amount of content must be found.

To meet the capacity challenge this has created for mobile operators, we believe an evolution is necessary in the architecture of mobile networks.

Therefore, in this work, we present a mobility management architecture (based on Distributed Mobility Management and IP flow mobility), that makes use of cross-layer information to enhance the mobile user's Quality of Experience. The work has been validated under a real proof-of-concept test bed. In addition, this work evaluates the mobility scheme in a new performance evaluation platform that embodies a hybrid approach, combining emulation with simulation.
