Data Management, IN Services and Interworking in DAWN - A Distributed Architecture for Wireless PCS Networks: An Overview

In this paper we present enhancements for a wireless PCS architecture which distributes processing from the mobile switching centers and cell sites. In a wireless environment all the call processing components need access to the subscriber data. The subscriber profile distributing scheme envisioned for this architecture provides a method to localize data in clusters and access it remotely, which leads to reduction in service profile transfers and better load sharing. Our propagation model of service profile transfers also reduces the number of times service profile updating is required. We also introduce a way to incorporate wireless intelligent network services in the call control phase and provide processing of these services in a distributed manner. The interworking needed to allow coexistence with conventional wireless networks is also presented.
