Mobility control beyond 3G systems

This paper deals with the issues of mobility control in mobile networks and the consequences for future generation networks. Mobility involves the update of the location information of the mobile user, as well as the redirection of the dataflow. Especially the latter is very challenging for network developers. Answers to this problem have been proposed for connection oriented networks, but, for connectionless networks, there is still no satisfying proposal. Hence this has consequences on architectural options for future networks in general, taking the impact of mobility into consideration.
