An Integrated Authentication and Mobility Management Mechanism for Fast Handover in NGN

We propose an integrated authentication and mobility management scheme for fast handover in NGN, and verify that the proposed scheme has lower latency time than the existing one through the integration of authentication and mobility management for handover signaling.

1. Introduction

The development of next generation wireless systems, which are characterized by seamless worldwide communication and support of various multimedia services, has been accelerated along with the development of wireless internet. Then new mobility schemes have studied by a variety of related works in order to provide seamless mobility service in NGN.
