Multi-Protocol Profiles to Support User Mobility Across Network Technologies

This paper presents the various aspects of the UMM (Unified Mobility Manager) multiprotocol subscriber base in detail. We introduce the concept of Incoming Call Handling (ICH) profiles that are the addressable entities in the UMM. An ICH profile contains all address level service data as well as the routing rules to the actual terminating devices. We discuss the issues of standard compliance and backward compatibility, and show how the UMM subscriber base helps harmonize services across network and technology boundaries.
