Improved Fast Location-based Handover With Integrated Security Features

摘要

Mobile communication systems of the future will be implemented as a hybrid network consisting of several former stand-alone and new networks. Therefore vertical handovers between different networks become more and more important. The existing handover procedures do not cope with the special needs of inter-network handovers in terms of latency and security issues. Location-based handovers are seen as a promising tool to provide an effective instrument for the choice of an appropriate network in a hybrid communication scenario, allowing low latency and integrated authentication. In this paper an improved location-based handover is shown. Therefore localization in hybrid networks is shortly analyzed. After that it is shown, how to integrate authentication into a handover procedure and that integrated authentication even can be realized, if the duration of the authentication takes more time than can be saved with the location-based handover preparation. This new approach leads to an increased number of successful handovers even compared with first versions of location-based handover algorithms.
