Software agents for enhancing messaging in a universal personal numbering service

This paper introduces the Universal Personal Numbering System (UPN), an application that works with a Personal Agent Mobility Management System (PAMMS) to manage multiple communications devices. It allows messages to reach the user on different phones or messaging devices using one single number. This paper includes details on the design of the UPN application and how it works with a UPN service adapter agent to notify non-telephone devices of incoming calls and await instructions from the user. Additionally, there is a description of the interface between the UPN application and a PC-based switch using the TAPI protocol.
