Highlevel Service Handover through a Contextual Framework

摘要

This paper presents an architecture for context driven handovers between highlevel (non-carrier) services. One of our key assumptions is that any change in context can cause a handover, and we discuss the several requirements to our architecture deriving from this assumption. We introduce a contextual extension to a general service model, which is the basis for our contextual framework. To demonstrate its applicability, our architecture is applied to a web service middleware exemplarily.
