Intelligent connection manager for seamless interworking of multi-technology mobile devices

Abstract

IMS). This paper discusses the Intelligent Wireless Connection Manager (IWCM), a critical component of a mobile device platform that enables seamless and transparent intertechnology mobility for user applications through IP session continuity, make-before-break handoff algorithms, and uniform quality of service (QoS) and policy management APIs. © 2011 Alcatel-Lucent.expand inexpensive Wi-Fi* hotspots and 3G/4G femtocell and picocell alternatives to Wi-Fi. One hundred percent wireless service coverage with overlapping areas of different access is becoming a reality.User equipment (UE) vendors are responding with a variety of multi-technology 3G, 4G, and Wi-Fi mobile devices such as laptops/netbooks with built-in or external USB-based modem cards, smartphones, and iPADs*. Still, users expect not only to always stay connected, but also to seamlessly maintain application sessions while crossing the invisible boundaries of different radio access technology (RAT) coverage
