Service architectures for the wireless world

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) 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.
