Network support for personal information services to PCS users

Future personal communications services (PCS) networks will provide mobile users with integrated personal information services and applications (PISA), such as personalized news and financial information, banking and file access. The authors propose a system architecture for delivery of PISA based on distributed servers, and discuss the connection-oriented support services it may require from the PCS network. In this architecture real mobility on the part of the user may result in virtual mobility of the server, which the authors propose be handled by a service handoff procedure broadly analogous to a PCS call handoff. They describe components of the service handoff procedure and the PCS network support they entail. They also discuss how users´ service profiles can be maintained in this architecture
