A New Integrated Mobile Architecture for Heterogeneous Wireless Networks

In wireless heterogeneous environment, the integration of wireless access network will be accomplished by seamless handover which contains many challenges i.e. service mobility, vertical handover, common authentication, unified accounting/billing, security mechanisms, QoS and service provisioning, etc. Toward this direction, our research aims to provide a complete integration of heterogeneous network architecture and support a fit mobility management for network to seamless handover. This paper offers an HIP-based vertical handover idea in heterogeneous wireless network. We propose a mobile integrated architecture in personal communication system. Moreover, we hope to contribute our research to beyond 4G (B4G) wireless networks.
