Mobile communication systems experienced high technical revolution. Nowadays, smart mobile devices have advanced computing aspects. In addition, they are provided with multiple network interfaces, wifi and 3G. Traffic redirection between these networks is addressed by the vertical handover process. Recently, vertical handover enhanced by the IEEE802.21 standards whichenables seamless mobility and interworking between most of the heterogeneous wireless access networks . A comparative performance study is done in this paper for the integration between WiFi and UMTS networks by taking advantage of the IEEE802.21 standard. The factors that affect the vertical handover process in this integration were studied such as the mobilespeed, and the application bitrate. Selecting five mobile node speeds 5,10,25,50,60 km/h whereas application bitrate is 64 kb/s and 3840 kb/s.
