A Performance Evaluation of Vertical Handoff Scheme between IEEE 802.16e and cdma2000 Networks

摘要

Interworking technologies in heterogeneous network environments has become a hot issue these days. This interworking technology would provide optimized services to users and also benefit service operators by reducing network construction and maintenance costs. This paper proposes network architecture for fast handoff between IEEE 802.16e and cdma2000 networks. The smoothly-coupled integration (SCI) scheme proposed in this paper adopts the advantages of both loosely-coupled integration and tightly-coupled integration schemes. Also, the proposed scheme can be implemented with minimal modification of existing IEEE 802.16e and cdma2000 networks.
