Abstract

Cellular networks, e.g. UMTS, provide voice and dataservices to mobile users. In hot spots where users need highspeed data services operators can deploy low-cost high-speedWLANs, e.g. 802.11, to cover hot-spots. This paper proposes apossible architecture of integrating UMTS and 802.11 WLAN.The architecture allows a mobile node to maintain data (PS)connection through WLAN and voice (CS) connection throughUMTS in parallel. This is especially attractive because WLANis currently used primarily for high-speed best-effort dataservice only.
