Zusammenfassung:Rapid development has equipped mobile devices with heterogeneous wireless access capabilities. A lot of work has been done on WLAN-3G integration to support seamless connectivity and global roaming. Most recent research trends focus on interwork gateway or intersystem roaming framework. In this paper, we introduce an application framework providing seamless connectivity for mobile devices across heterogeneous networks to support Voice-over-IP (VoIP) applications with high Quality-of-Service (QoS) requirements. The experimental results showed that the proposed system is able to support seamless connectivity for VoIP applications on multihomed Symbian devices.
