Personal Mobility in the ICEBERG Integrated Communication Network

Communication technology is currently seeing rapid growth, characterized by new access networks, end-devices and an ever growing user-community. However, there is a lack of integration between the di erent services: a user may have a cell-phone, a pager, a regular phone, a laptop, an e-mail account, and so on. But she has little control over managing communication services in a personalized, uni ed, and clean fashion across these devices. The Iceberg Project ([10, 23]) proposes an Internet-Core based approach for integration of telephony and data services across heterogeneous access networks. Personal mobility and personalized communication management as de ned by Iceberg are much richer than the corresponding concepts in traditional telephony. In this report, we present the design of the architectural components that provide personal mobility in the Iceberg integrated communication network. We present our model for a clean, extensible integration of end-devices and networks. We also discuss our mechanism for providing a high degree of personalization of communication. We have a prototype implementation of the integration components in a testbed consisting of four di erent communication services: GSM cell-phones, Voice-over-IP end-points, Voice-mail, and E-mail.
