Service architectures for the wireless world

In the last years, a variety of concepts for service integration and corresponding systems have gained momentum. On one hand, they aim at the inter-working and integration of classical telecommunications and data communications services. On the other hand, they are focusing on universal service access from a variety of end user systems. All these systems are driven by the concept of providing several technologies to users by keeping the peculiarity of each service. From the service point of view, the participants of WWRF Working Group 2 (Wireless World Research Forum: http://www.wireless-world-research.org/) believe that the service architectures of the Wireless World will be based on service personalization, service integration, and IP-based reachability. The paper presents the rationales the framework and the architecture proposed by WWRF-WG2 based on numerous contributions (WWRF: Book of Visions (2001)) from research and industry world wide.

Spice: A Service Platform for Future Mobile IMS Services

Todays wireless and mobile service platforms are typically monolithic and centralized in nature, and they do not support heterogeneous service access and the sharing of service usage experience. New sources of revenue for providers are expected to include tailored, personalized, and dynamically composed services that are fast to market, cost efficient, and provide compelling user experience. To meet the current market needs, the SPICE service delivery platform extends the conventional IMS by supporting advanced added-value services that are composed of more primitive services. We describe the IMS role and functions in SPICE, and the use of ontology and Semantic Web technologies for achieving a better knowledge management in mobile service platforms.
