CATS: Context-Aware Triggering System for Next Generation Networks

Considering context information, namely location, in order to create new services has become a commercial trend. The innovative approaches that context-aware mechanisms make possible are being targeted by service providers of diverse areas. On the other hand, Service Oriented Architectures play a central role in allowing component reuse and low cost service creation. Together with IP Multimedia Subsystem enable the convergence of telecommunications and web services, allowing the network transport technologies to be abstracted from the services above. By integrating these three technologies, a number of synergies can be explored. Existing services can be easily enriched with context information, made available on a variety of networks and new services can be composed using previously existing building blocks. This paper explains how this integration can be achieved, and demonstrates the potentialities of this architectural paradigm with a prototype service.
