VPN WISH IWCM prototype

When integrated with a UE device's network protocol stack, the IWCM provides standards-compliant(3GPP, 3GPP2, WiMAX, Wi-Fi) and service providerpolicy-based functionality that enables seamless andtransparent session and service continuity on intertechnology handovers to IP-based VoIP, video, anddata applications.We introduce this section by describing the UEside procedures for seamless inter-technology handover. Next, we present an overview of the IWCMreference architecture, followed by a more detaileddescription of its components.The WISH IWCM prototype, available at BellLabs, is used for a variety of customer demonstrations,trade shows, and ongoing research work.
