Next Generation Network (NGN) is envisioned to be an internetworking environment of heterogeneous networks to offer next generation services anywhere, anytime. It integrates the services of 2G/3G/4G networks by incorporating IPv4/IPv6 into a single service platform with Multi-Protocol Label Switching (MPLS). Several efforts have been carried out by researchers to integrate MPLS technology into IP networks and to access the mobile nodes connected through the NGN to provide service continuity with guaranteed quality of service. But, not much progress has been reported in recent past. Hence, in this paper, an integrated next generation IP-MPLS hybrid architecture for seamless mobility has been proposed to achieve seamless mobility with end to end quality of service. The performance of the proposed architecture has been tested by establishing a test bed in a simulated environment.
