Universal Inbox: Providing Extensible Personal Mobility and Service Mobility in an Integrated Communication Network

By Bhaskaran Raman, Randy H. Katz and Anthony D. Joseph


Communication technology has been seeing rapid growth, characterized by new access networks (e.g., cellular, pager, wireless-IP) and end-devices (e.g., PDAs, twoway pagers, multi-model access devices). There have been several efforts at integrating services across such heterogeneity. However, little work has been done on identifying an underlying architecture for such an integration. We identify the requirements for this in the context of an integrated network with heterogeneous end-points. The Universal Inbox provides (a) generic data type transformation, (b) customizable redirection of incoming communication based on user preference profiles, and (c) device name mapping and translation. We present an architecture mapping these functionalities to reusable infrastructure components realized as Internet services. The unique feature of the architecture is its extensibility -- it allows not only the integration of existing end-points, but also extension in terms of the enddevices and nov..
